Based on Audit Council Act 1933, Thailand establishes Audit Council as an institution accountable for financial government audit. On March 1, 1979, State Audit Act 1979 that revises the Law on Audit Council was enacted. The law changed the name Thailand Finance Audit Agency, which was preciously known as Audit Council into Office of The Auditor General of Thailand (OAG ).
Audit Council is an independent agency from other executive power and it’s fully responsible for setting its own direction and scope of audit without interference. The highest leader of Thailand Finance Audit Board is called Auditor General. It authorized OAG to extend its scope of its financial audit.
The task of Thailand’s OAG, as stated in Section 7 of the State Audit Act, is as follows:
