Supreme Council for National Reconstruction
The business of consolidating a new government began soon after the coup had been completed. Martial law was immediately put into force. On May 20, the Military Revolutionary Committee was renamed the Supreme Council for National Reconstruction (SCNR), and the following day a new cabinet was instituted. General Chang, the chairman of the committee, remained Army Chief of Staff, but also took on the additional offices of Prime Minister and Defense Minister, becoming formal head of the administration. The SCNR was formalized as a junta of the thirty highest-ranking military officers initially arranged in fourteen subcommittees, and assumed a wide-ranging responsibility that included the powers to promulgate laws, appoint cabinet posts, and oversee the functioning of the administration as a whole.
