Constitutional courts serve as guardians of constitutional supremacy through judicial review mechanisms. This study examines the authority and practices of Indonesia's Constitutional Court in comparative perspective with international best practices. Using comparative legal analysis, this research evaluates judicial review systems in Germany, South Korea, South Africa, and the United States to identify effective governance models. The study reveals that while Indonesia's Constitutional Court possesses comprehensive constitutional review authority, challenges remain in enforcement mechanisms, case backlog management, and institutional independence. International best practices demonstrate the importance of clear jurisdictional boundaries, efficient case processing, and robust enforcement powers. The research concludes that Indonesia can strengthen its constitutional court system by adopting selective best practices including streamlined procedures, enhanced enforcement mechanisms, and improved institutional safeguards while maintaining its unique constitutional framework.
