The main focus of the study is to analyze the authority of the Constitutional Court in adding new norms related to age requirements, which are part of the open legal policy of the legislature. The research method used is normative legal research with a legislative, conceptual, and case-based approach. The results of the study indicate that the Constitutional Court has the authority to review laws against the 1945 Constitution, including in assessing age requirements as an open legal policy that can be reviewed if it violates constitutional rights. However, the addition of new requirements/norms and inconsistent rulings create contradictions because they are inconsistent with the authority of the Constitutional Court and also lead to legal uncertainty. The conclusion of this research emphasizes the importance of the Constitutional Court's consistency in reviewing norms in laws that constitute open legal policies and the importance of clear boundaries between legislative and judicial authority to uphold the principles of constitutionality and the supremacy of law in a democratic state. %Z Dr. M.
