On 2 February 1971, one week after the coup, Amin declared himself President of Uganda, Commander-in-Chief of the Armed Forces, Uganda Army Chief of Staff, and Chief of Air Staff. He announced that he was suspending certain provisions of the Ugandan constitution, and soon instituted an Advisory Defence Council composed of military officers with himself as the chairman. Amin placed military tribunals above the system of civil law, appointed soldiers to top government posts and parastatal agencies, and informed the newly inducted civilian cabinet ministers that they would be subject to military discipline. Amin ruled by decree, and over the course of his rule he issued approximately 30 decrees.
