Space law is an area of the law that encompasses national and international law governing activities in outer space. International lawyers have been unable to agree on a uniform definition of the term "outer space," although most lawyers agree that outer space generally begins at the lowest altitude above sea level at which objects can orbit the Earth, approximately 100 km (62 mi).

The inception of the field of space law began with the launch of the world's first artificial satellite by the Soviet Union in October 1957. Named Sputnik 1, the satellite was launched as part of the International Geophysical Year. Since that time, space law has evolved and assumed more importance as mankind has increasingly come to use and rely on space-based resources.

Early developments[link]

Beginning in 1957, nations began discussing systems to ensure the peaceful use of outer space.^[1][2] Bilateral discussions between the United States and USSR in 1958 resulted in the presentation of issues to the UN for debate.^[1][3][4] In 1959, the UN created the Committee on the Peaceful Uses of Outer Space (COPUOS).^[5] COPUOS in turn created two subcommittees, the Scientific and Technical Subcommittee and the Legal Subcommittee. The COPUOS Legal Subcommittee has been a primary forum for discussion and negotiation of international agreements relating to outer space.

International treaties[link]

Five international treaties have been negotiated and drafted in the COPUOS:

• The 1967 Treaty on Principles Governing the Activities of States in the Exploration and Use of Outer Space, including the Moon and Other Celestial Bodies (the "Outer Space Treaty").
• The 1968 Agreement on the Rescue of Astronauts, the Return of Astronauts and the Return of Objects Launched into Outer Space (the "Rescue Agreement").
• The 1972 Convention on International Liability for Damage Caused by Space Objects (the "Liability Convention").
• The 1975 Convention on Registration of Objects Launched into Outer Space (the "Registration Convention").
• The 1979 Agreement Governing the Activities of States on the Moon and Other Celestial Bodies (the "Moon Treaty").

The outer space treaty is the most widely-adopted treaty, with 100 parties. ^[6] The rescue agreement, the liability convention and the registration convention all elaborate on provisions of the outer space treaty. UN delegates apparently intended^{[according to whom?]} that the moon treaty serve as a new comprehensive treaty which would supersede or supplement the outer space treaty, most notably by elaborating upon the outer space treaty's provisions regarding resource appropriation and prohibition of territorial sovereignty. ^[7] The moon treaty has only 13 parties, and many consider it to be a failed treaty due to its limited acceptance. ^[8] India is the only nation that has both signed the moon treaty and declared itself interested in going to the moon. India has not ratified the treaty; an analysis of India's treaty law is required to understand how this affects India legally. ^[9]

In addition, the 1963 Treaty Banning Nuclear Weapon Tests in the Atmosphere, in Outer Space, and Under Water ("Partial Test Ban Treaty") banned the testing of nuclear weapons in outer space.

International principles and declarations[link]

The five treaties and agreements of international space law cover "non-appropriation of outer space by any one country, arms control, the freedom of exploration, liability for damage caused by space objects, the safety and rescue of spacecraft and astronauts, the prevention of harmful interference with space activities and the environment, the notification and registration of space activities, scientific investigation and the exploitation of natural resources in outer space and the settlement of disputes." ^[10]

The United Nations General Assembly adopted five declarations and legal principles which encourage exercising the international laws, as well as unified communication between countries. The five declarations and principles are:

• The Declaration of Legal Principles Governing the Activities of States in the Exploration and Uses of Outer Space (1963)

All space exploration will be done with good intentions and is equally open to all States that comply with international law. No one nation may claim ownership of outer space or any celestial body. Activities carried out in space must abide by the international law and the nations undergoing these said activities must accept responsibility for the governmental or non-governmental agency involved. Objects launched into space are subject to their nation of belonging, including people. Objects, parts, and components discovered outside the jurisdiction of a nation will be returned upon identification. If a nation launches an object into space, they are responsible for any damages that occur internationally.

• The Principles Governing the Use by States of Artificial Earth Satellites for International Direct Television Broadcasting (1982)

Activities of this nature must be transpire in accordance with the sovereign rights of States. Said activities should "promote the free dissemination and mutual exchange of information and knowledge in cultural and scientific fields, assist in educational, social and economic development, particularly in the developing countries, enhance the qualities of life of all peoples and provide recreation with due respect to the political and cultural integrity of States." All States have equal rights to pursue these activities and must maintain responsibility for anything carried out under their boundaries of authority. States planning activities need to contact the Secretary-General of the United Nations with details of the undergoing activities.

• The Principles Relating to Remote Sensing of the Earth from Outer Space (1986)

Fifteen principles are stated under this category. The basic understanding comes from these descriptions given by the United Nations Office for Outer Space Affairs:

(a) The term "remote sensing" means the sensing of the Earth's surface from space by making use of the properties of electromagnetic waves emitted, reflected or :diffracted by the sensed objects, for the purpose of improving natural resources management, land use and the protection of the environment;

(b) The term "primary data" means those raw data that are acquired by remote sensors borne by a space object and that are transmitted or delivered to the ground :from space by telemetry in the form of electromagnetic signals, by photographic film, magnetic tape or any other means;

(c) The term "processed data" means the products resulting from the processing of the primary data, needed to make such data usable;

(d) The term "analysed information" means the information resulting from the interpretation of processed data, inputs of data and knowledge from other sources;

(e) The term "remote sensing activities" means the operation of remote sensing space systems, primary data collection and storage stations, and activities in :processing, interpreting and disseminating the processed data.^[11]

• The Principles Relevant to the Use of Nuclear Power Sources in Outer Space (1992)

"States launching space objects with nuclear power sources on board shall endeavour to protect individuals, populations and the biosphere against radiological hazards. The design and use of space objects with nuclear power sources on board shall ensure, with a high degree of confidence, that the hazards, in foreseeable operational or accidental circumstances, are kept below acceptable levels..."

• The Declaration on International Cooperation in the Exploration and Use of Outer Space for the Benefit and in the Interest of All States, Taking into Particular Account the Needs of Developing Countries (1996)

"States are free to determine all aspects of their participation in international cooperation in the exploration and use of outer space on an equitable and mutually acceptable basis. All States, particularly those with relevant space capabilities and with programmes for the exploration and use of outer space, should contribute to promoting and fostering international cooperation on an equitable and mutually acceptable basis. In this context, particular attention should be given to the benefit for and the interests of developing countries and countries with incipient space programmes stemming from such international cooperation conducted with countries with more advanced space capabilities.International cooperation should be conducted in the modes that are considered most effective and appropriate by the countries concerned, including, inter alia, governmental and non-governmental; commercial and non-commercial; global, multilateral, regional or bilateral; and international cooperation among countries in all levels of development."

Consensus[link]

The COPUOS operates on the basis of consensus, i.e. all committee and subcommittee delegates must agree on treaty language before it can be included in the final version of a treaty, and the committees cannot place new items on their agendas unless all member nations agree. One reason that the U.N. space treaties lack definitions and are unclear in other respects, is because it is easier to achieve consensus when language and terms are vague. In recent years, the COPUOS Legal Subcommittee has been unable to achieve consensus on discussion of a new comprehensive space agreement. It is also unlikely that the Subcommittee will be able to agree to amend the Outer Space Treaty in the foreseeable future. Many space faring nations seem to believe that discussing a new space agreement or amendment of the Outer Space Treaty would be futile and time consuming, because entrenched differences regarding resource appropriation, property rights and other issues relating to commercial activity make consensus unlikely.

1998 ISS agreement[link]

In addition to the international treaties that have been negotiated at the United Nations, the nations participating in the International Space Station have entered into the 1998 Agreement among the governments of Canada, Member States of the European Space Agency, Japan, Russian Federation, and the United States of America concerning cooperation on the Civil International Space Station (the "Space Station Agreement"). This Agreement provides, among other things, that NASA is the lead agency in coordinating the member states' contributions to and activities on the space station, and that each nation has jurisdiction over its own module(s). The Agreement also provides for protection of intellectual property and procedures for criminal prosecution. This Agreement may very well serve as a model for future agreements regarding international cooperation in facilities on the Moon and Mars, where the first off-world colonies and scientific/industrial bases are likely to be established. ^[12]

National law[link]

Space law also encompasses national laws, and many countries have passed national space legislation in recent years. The Outer Space Treaty requires parties to authorize and supervise national space activities, including the activities of non-governmental entities such as commercial and non-profit organizations. The Outer Space Treaty also incorporates the UN Charter by reference, and requires parties to ensure that activities are conducted in accordance with other forms of international law such as customary international law (the custom and practice of states).

The advent of commercial space activities beyond the scope of the satellite communications industry, and the development of many commercial spaceports, is leading many countries^[which?] to consider how to regulate private space activities. ^[13] The challenge is to regulate these activities in a manner that does not hinder or preclude investment, while still ensuring that commercial activities comply with international law. The developing nations are concerned that the space faring nations will monopolize space resources. ^[14]

Geostationary orbit allocation[link]

Satellites in geostationary orbit must all occupy a single ring above the equator, approximately 35,800 km into space. The requirement to space these satellites apart means that there is a limited number of orbital "slots" available, thus only a limited number of satellites can be placed in geostationary orbit. This has led to conflict between different countries wishing access to the same orbital slots (countries at the same longitude but differing latitudes). These disputes are addressed through the ITU allocation mechanism.^[15] Countries located at the Earth's equator have also asserted their legal claim to control the use of space above their territory,^[16] notably in 1976, when many countries located at the Earth's equator created the Bogota Declaration, in which they asserted their legal claim to control the use of space above their territory.^[17]

The future of space law[link]

While this field of the law is still in its infancy, it is in an era of rapid change and development. Arguably the resources of space are infinite. If commercial space transportation becomes widely available, with substantially lower launch costs, then all countries will be able to directly reap the benefits of space resources. In that situation, it seems likely that consensus will be much easier to achieve with respect to commercial development and human settlement of outer space. High costs are not the only factor preventing the economic exploitation of space: it is argued that space should be considered as a pristine environment worthy of protection and conservation, and that the legal regime for space should further protect it from being used as a resource for Earth's needs.^[18][19] Debate is also focused on whether space should continue to be legally defined as part of the “common heritage of man,” and therefore unavailable for national claims, or whether its legal definition should be changed to allow private property in space.^[20][18][21]

Michael Dodge, of Long Beach, Mississippi, is the first law school graduate to receive a space law certificate in the United States.^[22][23] Dodge graduated from the National Center for Remote Sensing, Air and Space Law at the University of Mississippi School of Law in 2008.^[24][25]

The University of Sunderland is the first UK University to offer a space law module as part of its LLB programme.^{[citation needed] [26]}

The University of Nebraska College of Law offers the U.S.’s first and only LL.M. in space and telecommunications law.^[27] Professor Frans von der Dunk, former Director of space law research at Leiden University joined the program in 2007. In addition to the LL.M., students can earn a J.D. at Nebraska Law with an emphasis in space and telecommunications law. The program also hosts three space and telecommunications conferences each year ^{[28][Full citation needed]}

From more than 10 years, the University Paris-Sud with the Institute of Space and Telecommunications Law offer a Master's degree in Space Activities and Telecommunications Law. This Master is supported by numerous companies of space and telecommunications sectors.^[29]

Space is the boundless, three-dimensional extent in which objects and events occur and have relative position and direction.^[1] Physical space is often conceived in three linear dimensions, although modern physicists usually consider it, with time, to be part of a boundless four-dimensional continuum known as spacetime. In mathematics,"spaces" are examined with different numbers of dimensions and with different underlying structures. The concept of space is considered to be of fundamental importance to an understanding of the physical universe. However, disagreement continues between philosophers over whether it is itself an entity, a relationship between entities, or part of a conceptual framework.

Debates concerning the nature, essence and the mode of existence of space date back to antiquity; namely, to treatises like the Timaeus of Plato, or Socrates in his reflections on what the Greeks called khora (i.e. "space"), or in the Physics of Aristotle (Book IV, Delta) in the definition of topos (i.e. place), or even in the later "geometrical conception of place" as "space qua extension" in the Discourse on Place (Qawl fi al-Makan) of the 11th century Arab polymath Alhazen.^[2] Many of these classical philosophical questions were discussed in the Renaissance and then reformulated in the 17th century, particularly during the early development of classical mechanics. In Isaac Newton's view, space was absolute - in the sense that it existed permanently and independently of whether there were any matter in the space.^[3] Other natural philosophers, notably Gottfried Leibniz, thought instead that space was a collection of relations between objects, given by their distance and direction from one another. In the 18th century, the philosopher and theologian George Berkeley attempted to refute the "visibility of spatial depth" in his Essay Towards a New Theory of Vision. Later, the metaphysician Immanuel Kant said neither space nor time can be empirically perceived, they are elements of a systematic framework that humans use to structure all experiences. Kant referred to "space" in his Critique of Pure Reason as being: a subjective "pure a priori form of intuition", hence it is an unavoidable contribution of our human faculties.

In the 19th and 20th centuries mathematicians began to examine non-Euclidean geometries, in which space can be said to be curved, rather than flat. According to Albert Einstein's theory of general relativity, space around gravitational fields deviates from Euclidean space.^[4] Experimental tests of general relativity have confirmed that non-Euclidean space provides a better model for the shape of space.

Philosophy of space[link]

Leibniz and Newton[link]

Gottfried Leibniz

In the seventeenth century, the philosophy of space and time emerged as a central issue in epistemology and metaphysics. At its heart, Gottfried Leibniz, the German philosopher-mathematician, and Isaac Newton, the English physicist-mathematician, set out two opposing theories of what space is. Rather than being an entity that independently exists over and above other matter, Leibniz held that space is no more than the collection of spatial relations between objects in the world: "space is that which results from places taken together".^[5] Unoccupied regions are those that could have objects in them, and thus spatial relations with other places. For Leibniz, then, space was an idealised abstraction from the relations between individual entities or their possible locations and therefore could not be continuous but must be discrete.^[6] Space could be thought of in a similar way to the relations between family members. Although people in the family are related to one another, the relations do not exist independently of the people.^[7] Leibniz argued that space could not exist independently of objects in the world because that implies a difference between two universes exactly alike except for the location of the material world in each universe. But since there would be no observational way of telling these universes apart then, according to the identity of indiscernibles, there would be no real difference between them. According to the principle of sufficient reason, any theory of space that implied that there could be these two possible universes, must therefore be wrong.^[8]

Isaac Newton

Newton took space to be more than relations between material objects and based his position on observation and experimentation. For a relationist there can be no real difference between inertial motion, in which the object travels with constant velocity, and non-inertial motion, in which the velocity changes with time, since all spatial measurements are relative to other objects and their motions. But Newton argued that since non-inertial motion generates forces, it must be absolute.^[9] He used the example of water in a spinning bucket to demonstrate his argument. Water in a bucket is hung from a rope and set to spin, starts with a flat surface. After a while, as the bucket continues to spin, the surface of the water becomes concave. If the bucket's spinning is stopped then the surface of the water remains concave as it continues to spin. The concave surface is therefore apparently not the result of relative motion between the bucket and the water.^[10] Instead, Newton argued, it must be a result of non-inertial motion relative to space itself. For several centuries the bucket argument was decisive in showing that space must exist independently of matter.

Kant[link]

Immanuel Kant

In the eighteenth century the German philosopher Immanuel Kant developed a theory of knowledge in which knowledge about space can be both a priori and synthetic.^[11] According to Kant, knowledge about space is synthetic, in that statements about space are not simply true by virtue of the meaning of the words in the statement. In his work, Kant rejected the view that space must be either a substance or relation. Instead he came to the conclusion that space and time are not discovered by humans to be objective features of the world, but are part of an unavoidable systematic framework for organizing our experiences.^[12]

Non-Euclidean geometry[link]

Spherical geometry is similar to elliptical geometry. On the surface of a sphere there are no parallel lines.

Euclid's Elements contained five postulates that form the basis for Euclidean geometry. One of these, the parallel postulate has been the subject of debate among mathematicians for many centuries. It states that on any plane on which there is a straight line L₁ and a point P not on L₁, there is only one straight line L₂ on the plane that passes through the point P and is parallel to the straight line L₁. Until the 19th century, few doubted the truth of the postulate; instead debate centered over whether it was necessary as an axiom, or whether it was a theory that could be derived from the other axioms.^[13] Around 1830 though, the Hungarian János Bolyai and the Russian Nikolai Ivanovich Lobachevsky separately published treatises on a type of geometry that does not include the parallel postulate, called hyperbolic geometry. In this geometry, an infinite number of parallel lines pass through the point P. Consequently the sum of angles in a triangle is less than 180° and the ratio of a circle's circumference to its diameter is greater than pi. In the 1850s, Bernhard Riemann developed an equivalent theory of elliptical geometry, in which no parallel lines pass through P. In this geometry, triangles have more than 180° and circles have a ratio of circumference-to-diameter that is less than pi.

Gauss and Poincaré[link]

Carl Friedrich Gauss

Henri Poincaré

Although there was a prevailing Kantian consensus at the time, once non-Euclidean geometries had been formalised, some began to wonder whether or not physical space is curved. Carl Friedrich Gauss, a German mathematician, was the first to consider an empirical investigation of the geometrical structure of space. He thought of making a test of the sum of the angles of an enormous stellar triangle and there are reports he actually carried out a test, on a small scale, by triangulating mountain tops in Germany.^[14]

Henri Poincaré, a French mathematician and physicist of the late 19th century introduced an important insight in which he attempted to demonstrate the futility of any attempt to discover which geometry applies to space by experiment.^[15] He considered the predicament that would face scientists if they were confined to the surface of an imaginary large sphere with particular properties, known as a sphere-world. In this world, the temperature is taken to vary in such a way that all objects expand and contract in similar proportions in different places on the sphere. With a suitable falloff in temperature, if the scientists try to use measuring rods to determine the sum of the angles in a triangle, they can be deceived into thinking that they inhabit a plane, rather than a spherical surface.^[16] In fact, the scientists cannot in principle determine whether they inhabit a plane or sphere and, Poincaré argued, the same is true for the debate over whether real space is Euclidean or not. For him, which geometry was used to describe space, was a matter of convention.^[17] Since Euclidean geometry is simpler than non-Euclidean geometry, he assumed the former would always be used to describe the 'true' geometry of the world.^[18]

Einstein[link]

Albert Einstein

In 1905, Albert Einstein published a paper on a special theory of relativity, in which he proposed that space and time be combined into a single construct known as spacetime. In this theory, the speed of light in a vacuum is the same for all observers—which has the result that two events that appear simultaneous to one particular observer will not be simultaneous to another observer if the observers are moving with respect to one another. Moreover, an observer will measure a moving clock to tick more slowly than one that is stationary with respect to them; and objects are measured to be shortened in the direction that they are moving with respect to the observer.

Over the following ten years Einstein worked on a general theory of relativity, which is a theory of how gravity interacts with spacetime. Instead of viewing gravity as a force field acting in spacetime, Einstein suggested that it modifies the geometric structure of spacetime itself.^[19] According to the general theory, time goes more slowly at places with lower gravitational potentials and rays of light bend in the presence of a gravitational field. Scientists have studied the behaviour of binary pulsars, confirming the predictions of Einstein's theories and non-Euclidean geometry is usually used to describe spacetime.

Mathematics[link]

In modern mathematics spaces are defined as sets with some added structure. They are frequently described as different types of manifolds, which are spaces that locally approximate to Euclidean space, and where the properties are defined largely on local connectedness of points that lie on the manifold. There are however, many diverse mathematical objects that are called spaces. For example, vector spaces such as function spaces may have infinite numbers of independent dimensions and a notion of distance very different to Euclidean space, and topological spaces replace the concept of distance with a more abstract idea of nearness.

Physics[link]

Classical mechanics[link]

Space is one of the few fundamental quantities in physics, meaning that it cannot be defined via other quantities because nothing more fundamental is known at the present. On the other hand, it can be related to other fundamental quantities. Thus, similar to other fundamental quantities (like time and mass), space can be explored via measurement and experiment.

Relativity[link]

Before Einstein's work on relativistic physics, time and space were viewed as independent dimensions. Einstein's discoveries showed that due to relativity of motion our space and time can be mathematically combined into one object — spacetime. It turns out that distances in space or in time separately are not invariant with respect to Lorentz coordinate transformations, but distances in Minkowski space-time along space-time intervals are—which justifies the name.

In addition, time and space dimensions should not be viewed as exactly equivalent in Minkowski space-time. One can freely move in space but not in time. Thus, time and space coordinates are treated differently both in special relativity (where time is sometimes considered an imaginary coordinate) and in general relativity (where different signs are assigned to time and space components of spacetime metric).

Furthermore, in Einstein's general theory of relativity, it is postulated that space-time is geometrically distorted- curved -near to gravitationally significant masses.^[20]

Experiments are ongoing to attempt to directly measure gravitational waves. This is essentially solutions to the equations of general relativity, which describe moving ripples of spacetime. Indirect evidence for this has been found in the motions of the Hulse-Taylor binary system.

Cosmology[link]

Relativity theory leads to the cosmological question of what shape the universe is, and where space came from. It appears that space was created in the Big Bang, 13.7 billion years ago and has been expanding ever since. The overall shape of space is not known, but space is known to be expanding very rapidly due to the Cosmic Inflation.

Spatial measurement[link]

The measurement of physical space has long been important. Although earlier societies had developed measuring systems, the International System of Units, (SI), is now the most common system of units used in the measuring of space, and is almost universally used.

Currently, the standard space interval, called a standard meter or simply meter, is defined as the distance traveled by light in a vacuum during a time interval of exactly 1/299,792,458 of a second. This definition coupled with present definition of the second is based on the special theory of relativity in which the speed of light plays the role of a fundamental constant of nature.

Geographical space[link]

Geography is the branch of science concerned with identifying and describing the Earth, utilizing spatial awareness to try to understand why things exist in specific locations. Cartography is the mapping of spaces to allow better navigation, for visualization purposes and to act as a locational device. Geostatistics apply statistical concepts to collected spatial data to create an estimate for unobserved phenomena.

Geographical space is often considered as land, and can have a relation to ownership usage (in which space is seen as property or territory). While some cultures assert the rights of the individual in terms of ownership, other cultures will identify with a communal approach to land ownership, while still other cultures such as Australian Aboriginals, rather than asserting ownership rights to land, invert the relationship and consider that they are in fact owned by the land. Spatial planning is a method of regulating the use of space at land-level, with decisions made at regional, national and international levels. Space can also impact on human and cultural behavior, being an important factor in architecture, where it will impact on the design of buildings and structures, and on farming.

Ownership of space is not restricted to land. Ownership of airspace and of waters is decided internationally. Other forms of ownership have been recently asserted to other spaces—for example to the radio bands of the electromagnetic spectrum or to cyberspace.

Public space is a term used to define areas of land as collectively owned by the community, and managed in their name by delegated bodies; such spaces are open to all, while private property is the land culturally owned by an individual or company, for their own use and pleasure.

Abstract space is a term used in geography to refer to a hypothetical space characterized by complete homogeneity. When modeling activity or behavior, it is a conceptual tool used to limit extraneous variables such as terrain.

In psychology[link]

Psychologists first began to study the way space is perceived in the middle of the 19th century. Those now concerned with such studies regard it as a distinct branch of psychology. Psychologists analyzing the perception of space are concerned with how recognition of an object's physical appearance or its interactions are perceived, see, for example, visual space.

Other, more specialized topics studied include amodal perception and object permanence. The perception of surroundings is important due to its necessary relevance to survival, especially with regards to hunting and self preservation as well as simply one's idea of personal space.

Several space-related phobias have been identified, including agoraphobia (the fear of open spaces), astrophobia (the fear of celestial space) and claustrophobia (the fear of enclosed spaces).

Lady Justice is the symbol of justice. Lady Justice is depicted as a goddess equipped with three symbols of justice: a sword symbolising the court's coercive power; scales representing an objective standard by which competing claims are weighed; and a blindfold indicating that justice is (or should be) meted out objectively, without fear or favor, regardless of identity, money, power, or weakness.^[1]

The Law^[2] is a system of rules and guidelines which are enforced through social institutions to govern behavior.^[3] Laws are made by governments, specifically by their legislatures. The formation of laws themselves may be influenced by a constitution (written or unwritten) and the rights encoded therein. The law shapes politics, economics and society in countless ways and serves as a social mediator of relations between people.

A general distinction can be made between civil law jurisdictions (including Canon and Socialist law), in which the legislature or other central body codifies and consolidates their laws and common law systems (including Sharia), where judge-made binding precedents are accepted. In some countries, religion may inform the law; for example, in jurisdictions that practice Islamic law, Jewish law or Canon law.

The adjudication of the law is generally divided into two main areas. Criminal law deals with conduct that is designated dishonest by the government and in which the guilty party may be imprisioned or fined. Civil law (not to be confused with civil law jurisdictions above) deals with disputes between individuals or organizations, in which compensation may be awarded to the wronged litigant.

Under civil law, the following specialties, among others, exist: Contract law regulates everything from buying a bus ticket to trading on derivatives markets. Property law regulates the transfer and title of personal property and real property. Trust law applies to assets held for investment and financial security. Tort law allows claims for compensation if a person's property are harmed. Constitutional law provides a framework for the creation of law, the protection of human rights and the election of political representatives. Administrative law is used to review the decisions of government agencies. International law governs affairs between sovereign states in activities ranging from trade to military action.

To implement and enforce the law and provide services to the public, a government's bureaucracy, the military and police are vital. While all these organs of the state are creatures created and bound by law, an independent legal profession and a vibrant civil society inform and support their progress^{[citation needed]}.

Law provides a rich source of scholarly inquiry into legal history, philosophy, economic analysis and sociology. Law also raises important and complex issues concerning equality, fairness, and justice. "In its majestic equality", said the author Anatole France in 1894, "the law forbids rich and poor alike to sleep under bridges, beg in the streets and steal loaves of bread."^[4] Writing in 350 BCE, the Greek philosopher Aristotle declared, "The rule of law is better than the rule of any individual."^[5]

In a presidential democracy, the constitution is sovereign and the central institutions for interpreting and creating law are the three main branches of government, namely an impartial judiciary, a democratic legislature, and an accountable executive. In parliamentary systems, the legislature is sovereign and appoints one of its members as the executive (often called the prime minister). The judicial branch is under the parliament.

Legal subjects[link]

All legal systems deal with the same basic issues, but jurisdictions categorise and identify its legal subjects in different ways. A common distinction is that between "public law" (a term related closely to the state, and including constitutional, administrative and criminal law), and "private law" (which covers contract, tort and property).^[6] In civil law systems, contract and tort fall under a general law of obligations, while trusts law is dealt with under statutory regimes or international conventions. International, constitutional and administrative law, criminal law, contract, tort, property law and trusts are regarded as the "traditional core subjects",^[7] although there are many further disciplines .

International law[link]

Providing a constitution for public international law, the United Nations system was agreed during World War II

International law can refer to three things: public international law, private international law or conflict of laws and the law of supranational organisations.

• Public international law concerns relationships between sovereign nations. The sources for public international law development are custom, practice and treaties between sovereign nations, such as the Geneva Conventions. Public international law can be formed by international organisations, such as the United Nations (which was established after the failure of the League of Nations to prevent the Second World War),^[8] the International Labour Organisation, the World Trade Organisation, or the International Monetary Fund. Public international law has a special status as law because there is no international police force, and courts (e.g. the International Court of Justice as the primary UN judicial organ) lack the capacity to penalise disobedience.^[9] However, a few bodies, such as the WTO, have effective systems of binding arbitration and dispute resolution backed up by trade sanctions.^[10]

• Conflict of laws (or "private international law" in civil law countries) concerns which jurisdiction a legal dispute between private parties should be heard in and which jurisdiction's law should be applied. Today, businesses are increasingly capable of shifting capital and labour supply chains across borders, as well as trading with overseas businesses, making the question of which country has jurisdiction even more pressing. Increasing numbers of businesses opt for commercial arbitration under the New York Convention 1958.^[11]

• European Union law is the first and, so far, only example of a internationally accepted legal system other than the UN and the World Trade Organisation. Given the trend of increasing global economic integration, many regional agreements—especially the Union of South American Nations—are on track to follow the same model. In the EU, sovereign nations have gathered their authority in a system of courts and political institutions. These institutions are allowed the ability to enforce legal norms both against or for member states and citizens in a manner which is not possible through public international law.^[12] As the European Court of Justice said in the 1960s, European Union law constitutes "a new legal order of international law" for the mutual social and economic benefit of the member states.^[13]

Constitutional and administrative law[link]

The French Declaration of the Rights of Man and of the Citizen, whose principles still have constitutional value

Constitutional and administrative law govern the affairs of the state. Constitutional law concerns both the relationships between the executive, legislature and judiciary and the human rights or civil liberties of individuals against the state. Most jurisdictions, like the United States and France, have a single codified constitution with a bill of rights. A few, like the United Kingdom, have no such document. A "constitution" is simply those laws which constitute the body politic, from statute, case law and convention. A case named Entick v Carrington^[14] illustrates a constitutional principle deriving from the common law. Mr Entick's house was searched and ransacked by Sheriff Carrington. When Mr Entick complained in court, Sheriff Carrington argued that a warrant from a Government minister, the Earl of Halifax, was valid authority. However, there was no written statutory provision or court authority. The leading judge, Lord Camden, stated that,

The great end, for which men entered into society, was to secure their property. That right is preserved sacred and incommunicable in all instances, where it has not been taken away or abridged by some public law for the good of the whole ... If no excuse can be found or produced, the silence of the books is an authority against the defendant, and the plaintiff must have judgment.^[15]

The fundamental constitutional principle, inspired by John Locke, holds that the individual can do anything but that which is forbidden by law, and the state may do nothing but that which is authorised by law.^[16][17] Administrative law is the chief method for people to hold state bodies to account. People can apply for judicial review of actions or decisions by local councils, public services or government ministries, to ensure that they comply with the law. The first specialist administrative court was the Conseil d'État set up in 1799, as Napoleon assumed power in France.^[18]

Criminal law[link]

Criminal law, also known as penal law, pertains to crimes and punishment.^[19] It thus regulates the definition of and penalties for offences found to have a sufficiently deleterious social impact but, in itself, makes no moral judgment on an offender nor imposes restrictions on society that physically prevents people from committing a crime in the first place.^[20] Investigating, apprehending, charging, and trying suspected offenders is regulated by the law of criminal procedure.^[21] The paradigm case of a crime lies in the proof, beyond reasonable doubt, that a person is guilty of two things. First, the accused must commit an act which is deemed by society to be criminal, or actus reus (guilty act).^[22] Second, the accused must have the requisite malicious intent to do a criminal act, or mens rea (guilty mind). However for so called "strict liability" crimes, an actus reus is enough.^[23] Criminal systems of the civil law tradition distinguish between intention in the broad sense (dolus directus and dolus eventualis), and negligence. Negligence does not carry criminal responsibility unless a particular crime provides for its punishment.^[24][25]

A depiction of a 1600s criminal trial, for witchcraft in Salem

Examples of crimes include murder, assault, fraud and theft. In exceptional circumstances defences can apply to specific acts, such as killing in self defence, or pleading insanity. Another example is in the 19th century English case of R v Dudley and Stephens, which tested a defence of "necessity". The Mignonette, sailing from Southampton to Sydney, sank. Three crew members and Richard Parker, a 17 year old cabin boy, were stranded on a raft. They were starving and the cabin boy was close to death. Driven to extreme hunger, the crew killed and ate the cabin boy. The crew survived and were rescued, but put on trial for murder. They argued it was necessary to kill the cabin boy to preserve their own lives. Lord Coleridge, expressing immense disapproval, ruled, "to preserve one's life is generally speaking a duty, but it may be the plainest and the highest duty to sacrifice it." The men were sentenced to hang, but public opinion was overwhelmingly supportive of the crew's right to preserve their own lives. In the end, the Crown commuted their sentences to six months in jail.^[26]

Criminal law offences are viewed as offences against not just individual victims, but the community as well.^[20] The state, usually with the help of police, takes the lead in prosecution, which is why in common law countries cases are cited as "The People v ..." or "R (for Rex or Regina) v ..." Also, lay juries are often used to determine the guilt of defendants on points of fact: juries cannot change legal rules. Some developed countries still condone capital punishment for criminal activity, but the normal punishment for a crime will be imprisonment, fines, state supervision (such as probation), or community service. Modern criminal law has been affected considerably by the social sciences, especially with respect to sentencing, legal research, legislation, and rehabilitation.^[27] On the international field, 111 countries are members of the International Criminal Court, which was established to try people for crimes against humanity.^[28]

Contract law[link]

The famous Carbolic Smoke Ball advertisement to cure influenza was held to be a unilateral contract

Contract law concerns enforceable promises, and can be summed up in the Latin phrase pacta sunt servanda (agreements must be kept).^[29] In common law jurisdictions, three key elements to the creation of a contract are necessary: offer and acceptance, consideration and the intention to create legal relations. In Carlill v Carbolic Smoke Ball Company a medical firm advertised that its new wonder drug, the smokeball, would cure people's flu, and if it did not, the buyers would get £100. Many people sued for their £100 when the drug did not work. Fearing bankruptcy, Carbolic argued the advert was not to be taken as a serious, legally binding offer. It was an invitation to treat, mere puff, a gimmick. But the court of appeal held that to a reasonable man Carbolic had made a serious offer. People had given good consideration for it by going to the "distinct inconvenience" of using a faulty product. "Read the advertisement how you will, and twist it about as you will", said Lord Justice Lindley, "here is a distinct promise expressed in language which is perfectly unmistakable".^[30]

"Consideration" indicates the fact that all parties to a contract have exchanged something of value. Some common law systems, including Australia, are moving away from the idea of consideration as a requirement. The idea of estoppel or culpa in contrahendo, can be used to create obligations during pre-contractual negotiations.^[31] In civil law jurisdictions, consideration is not required for a contract to be binding.^[32] In France, an ordinary contract is said to form simply on the basis of a "meeting of the minds" or a "concurrence of wills". Germany has a special approach to contracts, which ties into property law. Their 'abstraction principle' (Abstraktionsprinzip) means that the personal obligation of contract forms separately from the title of property being conferred. When contracts are invalidated for some reason (e.g. a car buyer is so drunk that he lacks legal capacity to contract)^[33] the contractual obligation to pay can be invalidated separately from the proprietary title of the car. Unjust enrichment law, rather than contract law, is then used to restore title to the rightful owner.^[34]

Tort law[link]

The "McLibel" two were involved in the longest running case in UK history for publishing a pamphlet criticising McDonald's restaurants.

Torts, sometimes called delicts, are civil wrongs. To have acted tortiously, one must have breached a duty to another person, or infringed some pre-existing legal right. A simple example might be accidentally hitting someone with a cricket ball.^[35] Under the law of negligence, the most common form of tort, the injured party could potentially claim compensation for his injuries from the party responsible. The principles of negligence are illustrated by Donoghue v Stevenson.^[36] A friend of Mrs Donoghue ordered an opaque bottle of ginger beer (intended for the consumption of Mrs Donoghue) in a café in Paisley. Having consumed half of it, Mrs Donoghue poured the remainder into a tumbler. The decomposing remains of a snail floated out. She claimed to have suffered from shock, fell ill with gastroenteritis and sued the manufacturer for carelessly allowing the drink to be contaminated. The House of Lords decided that the manufacturer was liable for Mrs Donoghue's illness. Lord Atkin took a distinctly moral approach, and said,

The liability for negligence ... is no doubt based upon a general public sentiment of moral wrongdoing for which the offender must pay ... The rule that you are to love your neighbour becomes in law, you must not injure your neighbour; and the lawyer's question, Who is my neighbour? receives a restricted reply. You must take reasonable care to avoid acts or omissions which you can reasonably foresee would be likely to injure your neighbour.^[37]

This became the basis for the four principles of negligence; (1) Mr Stevenson owed Mrs Donoghue a duty of care to provide safe drinks (2) he breached his duty of care (3) the harm would not have occurred but for his breach and (4) his act was the proximate cause, or not too remote a consequence, of her harm.^[36] Another example of tort might be a neighbour making excessively loud noises with machinery on his property.^[38] Under a nuisance claim the noise could be stopped. Torts can also involve intentional acts, such as assault, battery or trespass. A better known tort is defamation, which occurs, for example, when a newspaper makes unsupportable allegations that damage a politician's reputation.^[39] More infamous are economic torts, which form the basis of labour law in some countries by making trade unions liable for strikes,^[40] when statute does not provide immunity.^[41]

Property law[link]

A painting of the South Sea Bubble, one of the world's first ever speculations and crashes, led to strict regulation on share trading.^[42]

Property law governs valuable things that people call 'theirs'. Real property, sometimes called 'real estate' refers to ownership of land and things attached to it.^[43] Personal property, refers to everything else; movable objects, such as computers, cars, jewelry or intangible rights, such as stocks and shares. A right in rem is a right to a specific piece of property, contrasting to a right in personam which allows compensation for a loss, but not a particular thing back. Land law forms the basis for most kinds of property law, and is the most complex. It concerns mortgages, rental agreements, licences, covenants, easements and the statutory systems for land registration. Regulations on the use of personal property fall under intellectual property, company law, trusts and commercial law. An example of a basic case of most property law is Armory v Delamirie [1722].^[44] A chimney sweep's boy found a jewel encrusted with precious stones. He took it to a goldsmith to have it valued. The goldsmith's apprentice looked at it, sneakily removed the stones, told the boy it was worth three halfpence and that he would buy it. The boy said he would prefer the jewel back, so the apprentice gave it to him, but without the stones. The boy sued the goldsmith for his apprentice's attempt to cheat him. Lord Chief Justice Pratt ruled that even though the boy could not be said to own the jewel, he should be considered the rightful keeper ("finders keeper") until the original owner is found. In fact the apprentice and the boy both had a right of possession in the jewel (a technical concept, meaning evidence that something could belong to someone), but the boy's possessory interest was considered better, because it could be shown to be first in time. Possession may be nine tenths of the law, but not all.

This case is used to support the view of property in common law jurisdictions, that the person who can show the best claim to a piece of property, against any contesting party, is the owner.^[45] By contrast, the classic civil law approach to property, propounded by Friedrich Carl von Savigny, is that it is a right good against the world. Obligations, like contracts and torts are conceptualised as rights good between individuals.^[46] The idea of property raises many further philosophical and political issues. Locke argued that our "lives, liberties and estates" are our property because we own our bodies and mix our labour with our surroundings.^[47]

Equity and trusts[link]

The Court of Chancery, London, early 19th century

Equity is a body of rules that developed in England separately from the "common law". The common law was administered by judges. The Lord Chancellor on the other hand, as the King's keeper of conscience, could overrule the judge made law if he thought it equitable to do so.^[48] This meant equity came to operate more through principles than rigid rules. For instance, whereas neither the common law nor civil law systems allow people to split the ownership from the control of one piece of property, equity allows this through an arrangement known as a 'trust'. 'Trustees' control property, whereas the 'beneficial' (or 'equitable') ownership of trust property is held by people known as 'beneficiaries'. Trustees owe duties to their beneficiaries to take good care of the entrusted property.^[49] In the early case of Keech v Sandford [1722]^[50] a child had inherited the lease on a market in Romford, London. Mr Sandford was entrusted to look after this property until the child matured. But before then, the lease expired. The landlord had (apparently) told Mr Sandford that he did not want the child to have the renewed lease. Yet the landlord was happy (apparently) to give Mr Sandford the opportunity of the lease instead. Mr Sandford took it. When the child (now Mr Keech) grew up, he sued Mr Sandford for the profit that he had been making by getting the market's lease. Mr Sandford was meant to be trusted, but he put himself in a position of conflict of interest. The Lord Chancellor, Lord King, agreed and ordered Mr Sandford should disgorge his profits. He wrote,

I very well see, if a trustee, on the refusal to renew, might have a lease to himself few trust-estates would be renewed ... This may seem very hard, that the trustee is the only person of all mankind who might not have the lease; but it is very proper that the rule should be strictly pursued and not at all relaxed.

Of course, Lord King LC was worried that trustees might exploit opportunities to use trust property for themselves instead of looking after it. Business speculators using trusts had just recently caused a stock market crash. Strict duties for trustees made their way into company law and were applied to directors and chief executive officers. Another example of a trustee's duty might be to invest property wisely or sell it.^[51] This is especially the case for pension funds, the most important form of trust, where investors are trustees for people's savings until retirement. But trusts can also be set up for charitable purposes, famous examples being the British Museum or the Rockefeller Foundation.

Further disciplines[link]

Law spreads far beyond the core subjects into virtually every area of life. Three categories are presented for convenience, though the subjects intertwine and overlap.

Law and society

A trade union protest by UNISON while on strike

• Labour law is the study of a tripartite industrial relationship between worker, employer and trade union. This involves collective bargaining regulation, and the right to strike. Individual employment law refers to workplace rights, such as job securiy, health and safety or a minimum wage.
• Human rights, civil rights and human rights law are important fields to guarantee everyone basic freedoms and entitlements. These are laid down in codes such as the Universal Declaration of Human Rights, the European Convention on Human Rights (which founded the European Court of Human Rights) and the U.S. Bill of Rights. The Treaty of Lisbon makes the Charter of Fundamental Rights of the European Union legally binding in allmember states except Charter of Fundamental Rights of the European Union – Poland and the United Kingdom.^[52]
• Civil procedure and criminal procedure concern the rules that courts must follow as a trial and appeals proceed. Both concern a citizen's right to a fair trial or hearing.
• Evidence law involves which materials are admissible in courts for a case to be built.
• Immigration law and nationality law concern the rights of foreigners to live and work in a nation-state that is not their own and to acquire or lose citizenship. Both also involve the right of asylum and the problem of stateless individuals.
• Social security law refers to the rights people have to social insurance, such as jobseekers' allowances or housing benefits.
• Family law covers marriage and divorce proceedings, the rights of children and rights to property and money in the event of separation.

Law and commerce

• Company law sprang from the law of trusts, on the principle of separating ownership of property and control.^[53] The law of the modern company began with the Joint Stock Companies Act 1856, passed in the United Kingdom, which provided investors with a simple registration procedure to gain limited liability under the separate legal personality of the corporation.
• Commercial law covers complex contract and property law. The law of agency, insurance law, bills of exchange, insolvency and bankruptcy law and sales law are all important, and trace back to the mediæval Lex Mercatoria. The UK Sale of Goods Act 1979 and the US Uniform Commercial Code are examples of codified common law commercial principles.
• Admiralty law and the Law of the Sea lay a basic framework for free trade and commerce across the world's oceans and seas, where outside of a country's zone of control. Shipping companies operate through ordinary principles of commercial law, generalised for a global market. Admiralty law also encompasses specialised issues such as salvage, maritime liens, and injuries to passengers.
• Intellectual property law aims at safeguarding creators and other producers of intellectual goods and services. These are legal rights (copyrights, trademarks, patents, and related rights) which result from intellectual activity in the industrial, literary and artistic fields.^[54]
• Restitution deals with the recovery of someone else's gain, rather than compensation for one's own loss.
• Unjust enrichment When someone has been unjustly enriched (or there is an "absence of basis" for a transaction) at another's expense, this event generates the right to restitution to reverse that gain.

Law and regulation

The New York Stock Exchange trading floor after the Wall Street Crash of 1929, before tougher banking regulation was introduced

• Tax law involves regulations that concern value added tax, corporate tax, income tax.
• Banking law and financial regulation set minimum standards on the amounts of capital banks must hold, and rules about best practice for investment. This is to insure against the risk of economic crises, such as the Wall Street Crash of 1929.
• Regulation deals with the provision of public services and utilities. Water law is one example. Especially since privatisation became popular and took management of services away from public law, private companies doing the jobs previously controlled by government have been bound by varying degrees of social responsibility. Energy, gas, telecomms and water are regulated industries in most OECD countries.
• Competition law, known in the U.S. as antitrust law, is an evolving field that traces as far back as Roman decrees against price fixing and the English restraint of trade doctrine. Modern competition law derives from the U.S. anti-cartel and anti-monopoly statutes (the Sherman Act and Clayton Act) of the turn of the 20th century. It is used to control businesses who attempt to use their economic influence to distort market prices at the expense of consumer welfare.
• Consumer law could include anything from regulations on unfair contractual terms and clauses to directives on airline baggage insurance.
• Environmental law is increasingly important, especially in light of the Kyoto Protocol and the potential danger of climate change. Environmental protection also serves to penalise polluters within domestic legal systems.

Legal systems[link]

In general, legal systems can be split between civil law and common law systems.^[55] The term "civil law" referring to a legal system should not be confused with "civil law" as a group of legal subjects distinct from criminal or public law. A third type of legal system—accepted by some countries without separation of church and state—is religious law, based on scriptures. The specific system that a country is ruled by is often determined by its history, connections with other countries, or its adherence to international standards. The sources that jurisdictions adopt as authoritatively binding are the defining features of any legal system. Yet classification is a matter of form rather than substance, since similar rules often prevail.

Civil law[link]

First page of the 1804 edition of the Napoleonic Code

Civil law is the legal system used in most countries around the world today. In civil law the sources recognised as authoritative are, primarily, legislation—especially codifications in constitutions or statutes passed by government—and custom.^[56] Codifications date back millennia, with one early example being the Babylonian Codex Hammurabi. Modern civil law systems essentially derive from the legal practice of the 6th-century Eastern Roman Empire whose texts were rediscovered by late medieval Western Europe. Roman law in the days of the Roman Republic and Empire was heavily procedural, and lacked a professional legal class.^[57] Instead a lay magistrate, iudex, was chosen to adjudicate. Precedents were not reported, so any case law that developed was disguised and almost unrecognised.^[58] Each case was to be decided afresh from the laws of the State, which mirrors the (theoretical) unimportance of judges' decisions for future cases in civil law systems today. From 529–534 AD the Byzantine Emperor Justinian I codified and consolidated Roman law up until that point, so that what remained was one-twentieth of the mass of legal texts from before.^[59] This became known as the Corpus Juris Civilis. As one legal historian wrote, "Justinian consciously looked back to the golden age of Roman law and aimed to restore it to the peak it had reached three centuries before."^[60] The Justinian Code remained in force in the East until the fall of the Byzantine Empire. Western Europe, meanwhile, relied on a mix of the Theodosian Code and Germanic customary law until the Justinian Code was rediscovered in the 11th century, and scholars at the University of Bologna used it to interpret their own laws.^[61] Civil law codifications based closely on Roman law, alongside some influences from religious laws such as Canon law, continued to spread throughout Europe until the Enlightenment; then, in the 19th century, both France, with the Code Civil, and Germany, with the Bürgerliches Gesetzbuch, modernised their legal codes. Both these codes influenced heavily not only the law systems of the countries in continental Europe (e.g. Greece), but also the Japanese and Korean legal traditions.^[62][63] Today, countries that have civil law systems range from Russia and China to most of Central and Latin America.^[64] The United States follows the common law system described below.

Common law and equity[link]

King John of England signs Magna Carta

Common law and equity are legal systems where decisions by courts are explicitly acknowledged to be legal sources. The "doctrine of precedent", or stare decisis (Latin for "to stand by decisions") means that decisions by higher courts bind lower courts. Common law systems also rely on statutes, passed by the legislature, but may make less of a systematic attempt to codify their laws than in a "civil law" system. Common law originated from England and has been inherited by almost every country once tied to the British Empire (except Malta, Scotland, the U.S. state of Louisiana, and the Canadian province of Quebec). In medieval England, the Norman conquest led to a unification of various tribal customs and hence a law "common" to the whole country. The common law developed when the English monarchy had been weakened by the enormous cost of fighting for control over large parts of France. King John had been forced by his barons to sign a document limiting his authority to pass laws. This "great charter" or Magna Carta of 1215 also required that the King's entourage of judges hold their courts and judgments at "a certain place" rather than dispensing autocratic justice in unpredictable places about the country.^[65] A concentrated and elite group of judges acquired a dominant role in law-making under this system, and compared to its European counterparts the English judiciary became highly centralised. In 1297, for instance, while the highest court in France had fifty-one judges, the English Court of Common Pleas had five.^[66] This powerful and tight-knit judiciary gave rise to a rigid and inflexible system of common law.^[67] As a result, as time went on, increasing numbers of citizens petitioned the King to override the common law, and on the King's behalf the Lord Chancellor gave judgment to do what was equitable in a case. From the time of Sir Thomas More, the first lawyer to be appointed as Lord Chancellor, a systematic body of equity grew up alongside the rigid common law, and developed its own Court of Chancery. At first, equity was often criticised as erratic, that it varied according to the length of the Chancellor's foot.^[68] But over time it developed solid principles, especially under Lord Eldon.^[69] In the 19th century the two systems were fused into one another. In developing the common law and equity, academic authors have always played an important part. William Blackstone, from around 1760, was the first scholar to describe and teach it.^[70] But merely in describing, scholars who sought explanations and underlying structures slowly changed the way the law actually worked.^[71]

Religious law[link]

Religious law is explicitly based on religious precepts. Examples include the Jewish Halakha and Islamic Sharia—both of which translate as the "path to follow"—while Christian canon law also survives in some church communities. Often the implication of religion for law is unalterability, because the word of God cannot be amended or legislated against by judges or governments. However a thorough and detailed legal system generally requires human elaboration. For instance, the Quran has some law, and it acts as a source of further law through interpretation,^[72] Qiyas (reasoning by analogy), Ijma (consensus) and precedent. This is mainly contained in a body of law and jurisprudence known as Sharia and Fiqh respectively. Another example is the Torah or Old Testament, in the Pentateuch or Five Books of Moses. This contains the basic code of Jewish law, which some Israeli communities choose to use. The Halakha is a code of Jewish law which summarises some of the Talmud's interpretations. Nevertheless, Israeli law allows litigants to use religious laws only if they choose. Canon law is only in use by members of the Catholic Church, the Eastern Orthodox Church and the Anglican Communion.

A trial in the Ottoman Empire, 1879, when religious law applied under the Mecelle

Until the 18th century, Sharia law was practiced throughout the Muslim world in a non-codified form, with the Ottoman Empire's Mecelle code in the 19th century being first attempt at codifying elements of Sharia law. Since the mid-1940s, efforts have been made, in country after country, to bring Sharia law more into line with modern conditions and conceptions.^[73][74] In modern times, the legal systems of many Muslim countries draw upon both civil and common law traditions as well as Islamic law and custom. The constitutions of certain Muslim states, such as Egypt and Afghanistan, recognise Islam as the religion of the state, obliging legislature to adhere to Sharia.^[75] Saudi Arabia recognises Quran as its constitution, and is governed on the basis of Islamic law.^[76] Iran has also witnessed a reiteration of Islamic law into its legal system after 1979.^[77] During the last few decades, one of the fundamental features of the movement of Islamic resurgence has been the call to restore the Sharia, which has generated a vast amount of literature and affected world politics.^[78]

Legal theory[link]

History of law[link]

King Hammurabi is revealed the code of laws by the Mesopotamian sun god Shamash, also revered as the god of justice

The history of law is closely connected to the development of civilization. Ancient Egyptian law, dating as far back as 3000 BC, contained a civil code that was probably broken into twelve books. It was based on the concept of Ma'at, characterised by tradition, rhetorical speech, social equality and impartiality.^[79][80] By the 22nd century BC, the ancient Sumerian ruler Ur-Nammu had formulated the first law code, which consisted of casuistic statements ("if ... then ..."). Around 1760 BC, King Hammurabi further developed Babylonian law, by codifying and inscribing it in stone. Hammurabi placed several copies of his law code throughout the kingdom of Babylon as stelae, for the entire public to see; this became known as the Codex Hammurabi. The most intact copy of these stelae was discovered in the 19th century by British Assyriologists, and has since been fully transliterated and translated into various languages, including English, German, and French.^[81]

The Old Testament dates back to 1280 BC and takes the form of moral imperatives as recommendations for a good society. The small Greek city-state, ancient Athens, from about the 8th century BC was the first society to be based on broad inclusion of its citizenry, excluding women and the slave class. However, Athens had no legal science or single word for "law",^[82] relying instead on the three-way distinction between divine law (thémis), human decree (nomos) and custom (díkē).^[83] Yet Ancient Greek law contained major constitutional innovations in the development of democracy.^[84]

Roman law was heavily influenced by Greek philosophy, but its detailed rules were developed by professional jurists and were highly sophisticated.^[85][86] Over the centuries between the rise and decline of the Roman Empire, law was adapted to cope with the changing social situations and underwent major codification under Theodosius II and Justinian I.^[87] Although codes were replaced by custom and case law during the Dark Ages, Roman law was rediscovered around the 11th century when mediæval legal scholars began to research Roman codes and adapt their concepts. In mediæval England, royal courts developed a body of precedent which later became the common law. A Europe-wide Law Merchant was formed so that merchants could trade with common standards of practice rather than with the many splintered facets of local laws. The Law Merchant, a precursor to modern commercial law, emphasised the freedom to contract and alienability of property.^[88] As nationalism grew in the 18th and 19th centuries, the Law Merchant was incorporated into countries' local law under new civil codes. The Napoleonic and German Codes became the most influential. In contrast to English common law, which consists of enormous tomes of case law, codes in small books are easy to export and easy for judges to apply. However, today there are signs that civil and common law are converging.^[89] EU law is codified in treaties, but develops through the precedent laid down by the European Court of Justice.

The Constitution of India is the longest written constitution for a country, containing 444 articles, 12 schedules, numerous amendments and 117,369 words

Ancient India and China represent distinct traditions of law, and have historically had independent schools of legal theory and practice. The Arthashastra, probably compiled around 100 AD (although it contains older material), and the Manusmriti (c. 100–300 AD) were foundational treatises in India, and comprise texts considered authoritative legal guidance.^[90] Manu's central philosophy was tolerance and Pluralism, and was cited across Southeast Asia.^[91] This Hindu tradition, along with Islamic law, was supplanted by the common law when India became part of the British Empire.^[92] Malaysia, Brunei, Singapore and Hong Kong also adopted the common law. The eastern Asia legal tradition reflects a unique blend of secular and religious influences.^[93] Japan was the first country to begin modernising its legal system along western lines, by importing bits of the French, but mostly the German Civil Code.^[94] This partly reflected Germany's status as a rising power in the late 19th century. Similarly, traditional Chinese law gave way to westernisation towards the final years of the Ch'ing dynasty in the form of six private law codes based mainly on the Japanese model of German law.^[95] Today Taiwanese law retains the closest affinity to the codifications from that period, because of the split between Chiang Kai-shek's nationalists, who fled there, and Mao Zedong's communists who won control of the mainland in 1949. The current legal infrastructure in the People's Republic of China was heavily influenced by Soviet Socialist law, which essentially inflates administrative law at the expense of private law rights.^[96] Due to rapid industrialisation, today China is undergoing a process of reform, at least in terms of economic, if not social and political, rights. A new contract code in 1999 represented a move away from administrative domination.^[97] Furthermore, after negotiations lasting fifteen years, in 2001 China joined the World Trade Organisation.^[98]

Philosophy of law[link]

The philosophy of law is commonly known as jurisprudence. Normative jurisprudence is essentially political philosophy, and asks "what should law be?", while analytic jurisprudence asks "what is law?". John Austin's utilitarian answer was that law is "commands, backed by threat of sanctions, from a sovereign, to whom people have a habit of obedience".^[100] Natural lawyers on the other side, such as Jean-Jacques Rousseau, argue that law reflects essentially moral and unchangeable laws of nature. The concept of "natural law" emerged in ancient Greek philosophy concurrently and in entanglement with the notion of justice, and re-entered the mainstream of Western culture through the writings of Thomas Aquinas.

Hugo Grotius, the founder of a purely rationalistic system of natural law, argued that law arises from both a social impulse—as Aristotle had indicated—and reason.^[101] Immanuel Kant believed a moral imperative requires laws "be chosen as though they should hold as universal laws of nature".^[102] Jeremy Bentham and his student Austin, following David Hume, believed that this conflated the "is" and what "ought to be" problem. Bentham and Austin argued for law's positivism; that real law is entirely separate from "morality".^[103] Kant was also criticised by Friedrich Nietzsche, who rejected the principle of equality, and believed that law emanates from the will to power, and cannot be labelled as "moral" or "immoral".^{[104][105][106]}

In 1934, the Austrian philosopher Hans Kelsen continued the positivist tradition in his book the Pure Theory of Law.^[107] Kelsen believed that although law is separate from morality, it is endowed with "normativity"; meaning we ought to obey it. While laws are positive "is" statements (e.g. the fine for reversing on a highway is €500); law tells us what we "should" do. Thus, each legal system can be hypothesised to have a basic norm (Grundnorm) instructing us to obey. Kelsen's major opponent, Carl Schmitt, rejected both positivism and the idea of the rule of law because he did not accept the primacy of abstract normative principles over concrete political positions and decisions.^[108] Therefore, Schmitt advocated a jurisprudence of the exception (state of emergency), which denied that legal norms could encompass of all political experience.^[109]

Bentham's utilitarian theories remained dominant in law until the 20th century

Later in the 20th century, H. L. A. Hart attacked Austin for his simplifications and Kelsen for his fictions in The Concept of Law.^[110] Hart argued law is a system of rules, divided into primary (rules of conduct) and secondary ones (rules addressed to officials to administer primary rules). Secondary rules are further divided into rules of adjudication (to resolve legal disputes), rules of change (allowing laws to be varied) and the rule of recognition (allowing laws to be identified as valid). Two of Hart's students continued the debate: In his book Law's Empire, Ronald Dworkin attacked Hart and the positivists for their refusal to treat law as a moral issue. Dworkin argues that law is an "interpretive concept",^[111] that requires judges to find the best fitting and most just solution to a legal dispute, given their constitutional traditions. Joseph Raz, on the other hand, defended the positivist outlook and criticised Hart's "soft social thesis" approach in The Authority of Law.^[112] Raz argues that law is authority, identifiable purely through social sources and without reference to moral reasoning. In his view, any categorisation of rules beyond their role as authoritative instruments in mediation are best left to sociology, rather than jurisprudence.^[113]

Economic analysis of law[link]

In the 18th century Adam Smith presented a philosophical foundation for explaining the relationship between law and economics.^[114] The discipline arose partly out of a critique of trade unions and U.S. antitrust law. The most influential proponents, such as Richard Posner and Oliver Williamson and the so-called Chicago School of economists and lawyers including Milton Friedman and Gary Becker, are generally advocates of deregulation and privatisation, and are hostile to state regulation or what they see as restrictions on the operation of free markets.^[115]

Richard Posner, one of the Chicago School, runs a blog with Bank of Sweden Prize winning economist Gary Becker.^[116]

The most prominent economic analyst of law is 1991 Nobel Prize winner Ronald Coase, whose first major article, The Nature of the Firm (1937), argued that the reason for the existence of firms (companies, partnerships, etc.) is the existence of transaction costs.^[117] Rational individuals trade through bilateral contracts on open markets until the costs of transactions mean that using corporations to produce things is more cost-effective. His second major article, The Problem of Social Cost (1960), argued that if we lived in a world without transaction costs, people would bargain with one another to create the same allocation of resources, regardless of the way a court might rule in property disputes.^[118] Coase used the example of a nuisance case named Sturges v Bridgman, where a noisy sweetmaker and a quiet doctor were neighbours and went to court to see who should have to move.^[38] Coase said that regardless of whether the judge ruled that the sweetmaker had to stop using his machinery, or that the doctor had to put up with it, they could strike a mutually beneficial bargain about who moves house that reaches the same outcome of resource distribution. Only the existence of transaction costs may prevent this.^[119] So the law ought to pre-empt what would happen, and be guided by the most efficient solution. The idea is that law and regulation are not as important or effective at helping people as lawyers and government planners believe.^[120] Coase and others like him wanted a change of approach, to put the burden of proof for positive effects on a government that was intervening in the market, by analysing the costs of action.^[121]

Sociology of law[link]

Sociology of law is a diverse field of study that examines the interaction of law with society and overlaps with jurisprudence, economic analysis of law and more specialised subjects such as criminology.^[122] The institutions of social construction and legal frameworks are the relevant areas for the discipline's inquiry. At first, legal theorists were suspicious of the discipline. Kelsen attacked one of its founders, Eugen Ehrlich, who sought to make distinct the differences between positive law, which lawyers learn and apply, and other forms of 'law' or social norms that regulate everyday life, generally preventing conflicts from reaching lawyers and courts.^[123][124]

Max Weber in 1917, Weber began his career as a lawyer, and is regarded as one of the founders of sociology and sociology of law

Around 1900 Max Weber defined his "scientific" approach to law, identifying the "legal rational form" as a type of domination, not attributable to people but to abstract norms.^[125] Legal rationalism was his term for a body of coherent and calculable law which formed a precondition for modern political developments and the modern bureaucratic state and developed in parallel with the growth of capitalism.^[122] Another sociologist, Émile Durkheim, wrote in The Division of Labour in Society that as society becomes more complex, the body of civil law concerned primarily with restitution and compensation grows at the expense of criminal laws and penal sanctions.^[126] Other notable early legal sociologists included Hugo Sinzheimer, Theodor Geiger, Georges Gurvitch and Leon Petrażycki in Europe, and William Graham Sumner in the U.S.^[127][128]

Legal institutions[link]

The main institutions of law in industrialised countries are independent courts, representative parliaments, an accountable executive, the military and police, bureaucratic organisation, the legal profession and civil society itself. John Locke, in his Two Treatises of Government, and Baron de Montesquieu in The Spirit of the Laws, advocated for a separation of powers between the political, legislature and executive bodies.^[129] Their principle was that no person should be able to usurp all powers of the state, in contrast to the absolutist theory of Thomas Hobbes' Leviathan.^[130]

Max Weber and others reshaped thinking on the extension of state. Modern military, policing and bureaucratic power over ordinary citizens' daily lives pose special problems for accountability that earlier writers such as Locke or Montesquieu could not have foreseen. The custom and practice of the legal profession is an important part of people's access to justice, whilst civil society is a term used to refer to the social institutions, communities and partnerships that form law's political basis.

Judiciary[link]

A judiciary is a number of judges mediating disputes to determine outcome. Most countries have systems of appeal courts, answering up to a supreme legal authority. In the United States, this is the Supreme Court;^[131] in Australia, the High Court; in the UK, the Supreme Court;^[132] in Germany, the Bundesverfassungsgericht; in France, the Cour de Cassation.^[133][134] For most European countries the European Court of Justice in Luxembourg can overrule national law, when EU law is relevant. The European Court of Human Rights in Strasbourg allows citizens of the Council of Europe member states to bring cases relating to human rights issues before it.^[135]

Some countries allow their highest judicial authority to overrule legislation they determine to be unconstitutional. For example, in Brown v. Board of Education, the United States Supreme Court nullified many state statutes that had established racially segregated schools, finding such statutes to be incompatible with the Fourteenth Amendment to the United States Constitution.^[136]

A judiciary is theoretically bound by the constitution, just as all other government bodies are. In most countries judges may only interpret the constitution and all other laws. But in common law countries, where matters are not constitutional, the judiciary may also create law under the doctrine of precedent. The UK, Finland and New Zealand assert the ideal of parliamentary sovereignty, whereby the unelected judiciary may not overturn law passed by a democratic legislature.^[137]

In communist states, such as China, the courts are often regarded as parts of the executive, or subservient to the legislature; governmental institutions and actors exert thus various forms of influence on the judiciary.^[138] In Muslim countries, courts often examine whether state laws adhere to the Sharia: the Supreme Constitutional Court of Egypt may invalidate such laws,^[139] and in Iran the Guardian Council ensures the compatibility of the legislation with the "criteria of Islam".^[139][140]

Legislature[link]

The debating chamber of the European Parliament

Prominent examples of legislatures are the Houses of Parliament in London, the Congress in Washington D.C., the Bundestag in Berlin, the Duma in Moscow, the Parlamento Italiano in Rome and the Assemblée nationale in Paris. By the principle of representative government people vote for politicians to carry out their wishes. Although countries like Israel, Greece, Sweden and China are unicameral, most countries are bicameral, meaning they have two separately appointed legislative houses.^[141]

In the 'lower house' politicians are elected to represent smaller constituencies. The 'upper house' is usually elected to represent states in a federal system (as in Australia, Germany or the United States) or different voting configuration in a unitary system (as in France). In the UK the upper house is appointed by the government as a house of review. One criticism of bicameral systems with two elected chambers is that the upper and lower houses may simply mirror one another. The traditional justification of bicameralism is that an upper chamber acts as a house of review. This can minimise arbitrariness and injustice in governmental action.^[142]

To pass legislation, a majority of the members of a legislature must vote for a bill (proposed law) in each house. Normally there will be several readings and amendments proposed by the different political factions. If a country has an entrenched constitution, a special majority for changes to the constitution may be required, making changes to the law more difficult. A government usually leads the process, which can be formed from Members of Parliament (e.g. the UK or Germany). However, in a presidential system, the government is usually formed by an executive and his or her appointed cabinet officials (e.g. the United States or Brazil).^[143]

Executive[link]

The G20 meetings are composed of representatives of each country's executive branch

The executive in a legal system serves as a government's centre of political authority. In a parliamentary system, as with Britain, Italy, Germany, India, and Japan, the executive is known as the cabinet, and composed of members of the legislature. The executive is chosen by the Prime Minister or Chancellor, whose office holds power under the confidence of the legislature. Because popular elections appoint political parties to govern, the leader of a party can change in between elections.^[144]

The head of state is apart from the executive, and symbolically enacts laws and acts as representative of the nation. Examples include the German president (appointed by members of federal and state Parliaments) the Queen of the United Kingdom (a hereditary title), and the Austrian president (elected by popular vote). The other important model is the presidential system, found in France, the U.S. and Russia. In presidential systems, the executive acts as both head of state and head of government, and has power to appoint an unelected cabinet. Under a presidential system, the executive branch is separate from the legislature to which it is not accountable.^[145][146]

Although the role of the executive varies from country to country, usually it will propose the majority of legislation, and propose government agenda. In presidential systems, the executive often has the power to veto legislation. Most executives in both systems are responsible for foreign relations, the military and police, and the bureaucracy. Ministers or other officials head a country's public offices, such as a foreign ministry or interior ministry. The election of a different executive is therefore capable of revolutionising an entire country's approach to government.

Military and police[link]

U.S. Customs and Border Protection officers

While military organizations have existed as long as government itself, the idea of a standing police force is relatively modern concept. For example, Mediæval England's system of traveling criminal courts, or assizes, used show trials and public executions to instill communities with fear to maintain control.^[147] The first modern police were probably those in 17th-century Paris, in the court of Louis XIV,^[148] although the Paris Prefecture of Police claim they were the world's first uniformed policemen.^[149]

Max Weber famously argued that the state is that which controls the monopoly on the legitimate use of force.^[150][151] The military and police carry out enforcement at the request of the government or the courts. The term failed state refers to states that cannot implement or enforce policies; their police and military no longer control security and order and society moves into anarchy, the absence of government.^[152]

Bureaucracy[link]

The United Nations' New York headquarters houses civil servants that serve its 192 member states.

The etymology of "bureaucracy" derives from the French word for "office" (bureau) and the Ancient Greek for word "power" (kratos).^[153] Like the military and police, a legal system's government servants and bodies that make up its bureaucracy carry out the directives of the executive. One of the earliest references to the concept was made by Baron de Grimm, a German author who lived in France. In 1765 he wrote,

The real spirit of the laws in France is that bureaucracy of which the late Monsieur de Gournay used to complain so greatly; here the offices, clerks, secretaries, inspectors and intendants are not appointed to benefit the public interest, indeed the public interest appears to have been established so that offices might exist.^[154]

Cynicism over "officialdom" is still common, and the workings of public servants is typically contrasted to private enterprise motivated by profit.^[155] In fact private companies, especially large ones, also have bureaucracies.^[156] Negative perceptions of "red tape" aside, public services such as schooling, health care, policing or public transport are a crucial state function making public bureaucratic action the locus of government power.^[156]

Writing in the early 20th century, Max Weber believed that a definitive feature of a developed state had come to be its bureaucratic support.^[157] Weber wrote that the typical characteristics of modern bureaucracy are that officials define its mission, the scope of work is bound by rules, management is composed of career experts, who manage top down, communicating through writing and binding public servants' discretion with rules.^[158]

Legal profession[link]

In civil law systems such as those of France, Germany, Italy, Spain and Greece, there is a distinct category of notary, a legally trained public official, compensated by the parties to a transaction.^[159] This is a 16th-century painting of such a notary by Flemish painter Quentin Massys.

A corollary of the rule of law is the existence of a legal profession sufficiently autonomous to be able to invoke the authority of the independent judiciary; the right to assistance of an advocate in a court proceeding emanates from this corollary—in England the function of barrister or advocate is distinguished from legal counselor (solicitor).^[160] As the European Court of Human Rights has stated, the law should be adequately accessible to everyone and people should be able to foresee how the law affects them.^[161]

In order to maintain professionalism, the practice of law is typically overseen by either a government or independent regulating body such as a bar association, bar council or law society. Modern lawyers achieve distinct professional identity through specified legal procedures (e.g. successfully passing a qualifying examination), are required by law to have a special qualification (a legal education earning the student a Bachelor of Laws, a Bachelor of Civil Law or a Juris Doctor degree^[162]), and are constituted in office by legal forms of appointment (being admitted to the bar). Most Muslim countries have developed similar rules about legal education and the legal profession, but some still allow lawyers with training in traditional Islamic law to practice law before personal status law courts.^[163] In China and other developing countries there are not sufficient professionally-trained people to staff the existing judicial systems, and, accordingly, formal standards are more relaxed.^[164]

Once accredited, a lawyer will often work in a law firm, in a chambers as a sole practitioner, in a government post or in a private corporation as an internal counsel. In addition a lawyer may become a legal researcher who provides on-demand legal research through a library, a commercial service or through freelance work. Many people trained in law put their skills to use outside the legal field entirely.^[165]

Significant to the practice of law in the common law tradition is the legal research to determine the current state of the law. This usually entails exploring case-law reports, legal periodicals and legislation. Law practice also involves drafting documents such as court pleadings, persuasive briefs, contracts, or wills and trusts. Negotiation and dispute resolution skills (including ADR techniques) are also important to legal practice, depending on the field.^[166]

Civil society[link]

A march in Washington D.C. during the U.S. Civil Rights Movement in 1963

Classical republican concept of "civil society" dates back to Hobbes and Locke.^[167] Locke saw civil society as people who have "a common established law and judicature to appeal to, with authority to decide controversies between them."^[168] German philosopher Georg Wilhelm Friedrich Hegel distinguished the "state" from "civil society" (burgerliche Gesellschaft) in Elements of the Philosophy of Right.^[169]

Hegel believed that civil society and the state were polar opposites, within the scheme of his dialectic theory of history. The modern dipole state–civil society was reproduced in the theories of Alexis de Tocqueville and Karl Marx.^[170][171] Nowadays in post-modern theory civil society is necessarily a source of law, by being the basis from which people form opinions and lobby for what they believe law should be. As Australian barrister and author Geoffrey Robertson QC wrote of international law,

... one of its primary modern sources is found in the responses of ordinary men and women, and of the non-governmental organizations which many of them support, to the human rights abuses they see on the television screen in their living rooms.^[172]

Freedom of speech, freedom of association and many other individual rights allow people to gather, discuss, criticise and hold to account their governments, from which the basis of a deliberative democracy is formed. The more people are involved with, concerned by and capable of changing how political power is exercised over their lives, the more acceptable and legitimate the law becomes to the people. The most familiar institutions of civil society include economic markets, profit-oriented firms, families, trade unions, hospitals, universities, schools, charities, debating clubs, non-governmental organisations, neighbourhoods, churches, and religious associations.^[173]
