Interfaith marriage is a family law issue that continues to generate debate in Indonesia because it lies at the intersection of the protection of citizens' constitutional rights, religious values, and human rights principles. This debate has become increasingly prominent after the Constitutional Court, through Decision Number 24/PUU-XX/2022, affirmed the constitutionality of Article 2 paragraph (1) of Law Number 1 of 1974 concerning Marriage. This study aims to analyze the constitutionality of the prohibition on interfaith marriage from the perspective of Islamic law and human rights and to examine the relevance of the Constitutional Court's decision to the principles of the Indonesian constitution. This research is a normative legal research with a statutory approach, a conceptual approach, a case approach, and a comparative approach. The legal materials are analyzed qualitatively through a descriptive-analytical method by reviewing laws and regulations, Constitutional Court decisions, international human rights instruments, and Islamic legal literature. The results of the study indicate that the prohibition on interfaith marriage is a constitutional legal policy because it is in line with the principle of Belief in One Almighty God as Indonesia's constitutional identity and is a form of open legal policy of lawmakers. From an Islamic legal perspective, this prohibition has a strong normative basis in the Qur'an, the Hadith, and the objectives of the maqāṣid al-syarī'ah (the principles of Islamic law), particularly the protection of religion, lineage, and the well-being of the family. Meanwhile, from a human rights perspective, this regulation cannot be classified as a human rights violation, but rather as a justifiable constitutional limitation as long as it meets the principles of legality, legitimate purpose, necessity, and proportionality. This research proposes the concept of constitutional fiqh as an integrative framework that harmonizes Islamic law, the constitution, and human rights in the formation of family law in Indonesia.
