The Commission Against Corruption (CCAC; Chinese: 廉政公署; Portuguese: Comissariado contra a Corrupção) is the statutory independent anti-corruption body of Macau with the primary objective of combating corruption, bribery, and other illicit activities in both the public and private sectors. Established in 1999 under the Article 59 of the Macau Basic Law, the CCAC is headed by the Commissioner, who reports directly to the Chief Executive of Macau.
The establishment of the CCAC came as a response to growing concerns over corruption and maladministration in Macau during the late 1990s, as the region transitioned from Portugal to China. The commission was created with the aim of ensuring transparency, accountability, and the rule of law, in line with Macau's Basic Law and the principle of "one country, two systems." Since its inception, the CCAC has played a critical role in Macau's fight against corruption and has contributed significantly to the region's reputation for good governance and adherence to the rule of law.
