<![CDATA[Abstract: Implementation of constitutional principles in Religious Court decisions in Indonesia involves several complex aspects. Religious courts play an important role in resolving family disputes and Islamic law issues, but are often influenced by various external factors that can undermine their independence. Research method used is a qualitative approach that analyzes legal documents, laws and regulations, and related court decisions. This analysis aims to identify and analyze the challenges faced in the application of constitutional principles in Religious Court decisions in Indonesia. Results from this study show that there are administrative interventions, lack of public understanding of constitutional principles and lack of human resources in the judiciary. In addition, there is the problem of harmonization of positive law and Islamic law which often causes confusion in law enforcement. Our study suggests the need to increase the capacity of judicial institutions, improve public legal education, and strengthen the principle of judicial independence. This research is expected to contribute to the development of a fairer and more transparent legal system in Indonesia.Keywords: Constitutional Law, Islamic Family Law, Religious Courts & Legal Harmonization.
