Abstract
In the Indonesian Government System, the president is the supreme authority of the government under the 1945 Constitution of the State of the Republic of Indonesia. After 4 (four) amendments to the 1945 Constitution, the presidential power experienced a shift in function and role as a result of the magnitude of the flow of political interests, so that almost all the power of the president on the authority of legislation in the 1945 Constitution of the 1945 Constitution largely lacked a permanent legal power and formal juridical. We know that the substance of the authority of presidential legislation if based on the presidential system of government does not exist and is not given real space. Consequently, the president as the mandate of the people's sovereignty must be able to control the system of government even though the fact that there is dominance of the legislative institution to the presidential institution together with the cabinet that is the authority of presidential legislation in the constitution of the state 1945 Constitution has no law forces so that the wheel of development does not run normally -target is planned. The hope is that our country's constitution must be able to guarantee the principle of balance of authority and mutual supervision that governs the legislation of the president against the product of the law.
