This study aims to analyze the strengthening of the Religious Courts' role in resolving Islamic economic disputes through a juridical examination of the dynamics of authority and absolute jurisdiction within the Indonesian legal system. The research employs a normative legal method using statutory, conceptual, and case approaches. The data sources consist of primary legal materials in the form of legislation and court decisions, as well as secondary legal materials derived from books and relevant scholarly journal articles. The findings reveal that the authority of the Religious Courts in resolving Islamic economic disputes has been firmly established through Law Number 3 of 2006 and further reinforced by the Constitutional Court Decision Number 93/PUU-X/2012, which confirms the absolute jurisdiction of the Religious Courts over Islamic economic disputes through litigation mechanisms. Nevertheless, the implementation of such authority continues to face various challenges, including the increasing complexity of modern Islamic financial transactions, the rapid development of financial technology, limitations in human resources, and the need for harmonization of substantive and procedural laws. Therefore, strengthening institutional capacity, updating regulations, developing jurisprudence, and optimizing judicial technology are strategic measures to enhance the effectiveness of Islamic economic dispute resolution. This study concludes that strengthening the role of the Religious Courts is essential for ensuring legal certainty and supporting the sustainable development of the Islamic economic sector in Indonesia.
