The Constitutional Court has the authority to review laws against the 1945 Constitution in order to uphold constitutional supremacy and protect citizens’ constitutional rights. This study aims to analyze the importance of formal requirements in judicial review applications and the legal considerations of the Constitutional Court in Decision Number 7/PUU-XXIV/2026. This research uses a normative legal method with statutory and case approaches. The results show that compliance with formal requirements is essential to maintain legal certainty, orderly judicial proceedings, and the principle of due process of law. In the a quo decision, the Court declared the application inadmissible because the applicants failed to fulfill administrative requirements, namely signatures and supporting evidence. Therefore, formal requirements serve as an important basis for maintaining the legitimacy and effectiveness of constitutional adjudication. The decision also demonstrates that procedural compliance is an integral component of constitutional justice. Proper fulfillment of procedural requirements ensures equal treatment before the law, prevents procedural abuse, and enables the Court to examine substantive constitutional issues effectively. These findings strengthen public confidence in the judicial system and reinforce the rule.
