Su'a Rimoni Ah Chong is a Samoan politician and former Controller and Chief Auditor of Samoa. He currently served as the leader of Samoa Party. As the Controller and Chief Auditor, Su'a Rimoni's efforts against government corruption in Samoa earned him international notability.
From 1992 to 1995 he refused to authorise illegal payments to Cabinet Ministers as Controller and Chief Auditor. In 1994 he tabled an Annual Report to Parliament which revealed wide scale corruption in the HRPP government under Tofilau Eti Alesana. The report implicated six out of 13 ministers in improper activities and payments. The government's response was to set up a Commission of Inquiry to discredit the Report.
The Commission looked not into the irregularities, but into the Chief Auditor himself. Included among the committee's members were several individuals criticised in his report.
In July 1995 The government suspended Sua. He then sued the government stating that under the constitution the Controller and Chief Auditor is only answerable to Parliament. As such the HRPP changed the Constitution making the position a Cabinet appointment and sacking Su'a in the process.
