Jakarta — Indonesia’s Constitutional Court is weighing whether to allow interfaith marriages, a debate that’s stirring up questions about religious freedom and national identity. A judge cautioned against directly comparing Indonesia’s marriage laws to those of other countries, like England or Canada, during a preliminary hearing on January 9, 2026.
Marriage Law Debate: Indonesia’s Court Considers Interfaith Unions
The case centers on a challenge to a 1974 law amended in 2019, with petitioners arguing it violates their constitutional rights.
- Three civil society members filed a petition challenging Article 2, paragraph (1) of Law Number 16 of 2019.
- Constitutional Judge Arsul Sani warned against equating Indonesian law with international standards.
- Petitioners argue the current law infringes on their right to have interfaith marriages legally recognized.
- The court could potentially open the door to same-sex marriage if it rules broadly in favor of the petitioners, the judge warned.
What’s the core of this legal challenge? The petitioners are arguing that a key phrase in Indonesian marriage law – “according to the laws of their respective religions and beliefs” – is too vague and prevents legally recognizing interfaith marriages where both partners follow their own religious guidelines.
Judge Arsul Sani emphasized that marriage laws aren’t simply legal codes; they’re deeply intertwined with a nation’s social contracts and core beliefs. “Marriage laws are products of a country’s legislation and constitution, so they inevitably differ,” he said during the hearing for case number 265/PUU-XXIII/2025.
National Philosophy vs. International Norms
Sani pointed out that Indonesia’s legal framework is rooted in Pancasila, the country’s foundational philosophy emphasizing belief in one God. This differs from nations where marriage might be viewed as a universal human right. He argued that a direct comparison isn’t “balanced,” as some legal matters are tied to ideology and societal norms.
The judge also raised concerns that a ruling based solely on human rights arguments and international comparisons could have unintended consequences, potentially extending to same-sex marriage. “This is not limited to Muslims; it affects social life and state affairs,” Sani cautioned.
However, Sani clarified he wasn’t judging the merits of different legal systems. He urged the petitioners to bolster their case with robust legal, sociological, and comparative studies. He believes relying solely on foreign laws is a weak argument.
Uswatun Hasanah, one of the petitioners hoping to marry a partner of a different faith, explained that the current provision prevents them from legally registering their marriage. The petitioners are seeking a court declaration that Article 2, paragraph (1) should not be interpreted to prohibit interfaith marriages conducted in accordance with each partner’s religious laws.
The disputed article reads: “Marriage is lawful if it is conducted according to the laws of their respective religions and beliefs.”
