The research method used is normative research with a qualitative approach, through literature studies and analysis of constitutional documents and relevant laws and regulations. Data were obtained from various sources, including the text of the 1945 Constitution before and after the amendment, academic literature, and the results of interviews with constitutional law experts. The results of the study indicate that the amendment to the 1945 Constitution has brought significant changes in the limitation of executive and legislative powers.
