A nine-member panel at the Federal Court of Malaysia led by Chief Justice Tengku Maimun ruled in a unanimous decision that Section 66A of the Administration of the Religion of Islam (State of Selangor) Enactment of 2003 was unconstitutional and void as the power of judicial review that it conferred was not a power that the Selangor state legislative assembly was authorized to give. The petition arose out of the High Court consideration of an application for judicial review wherein an organizational petitioner, the SIS Forum (of Malaysia), sought to challenge the validity of a fatwā [advisory Islamic law opinion].The Court stated that it is not concerned with the procedural or substantive validity of the fatwā, and was not asked to determine the courts are authorized to undertake such evaluations in the first place under clause (1A) of Article 121 of Malaysia’s Federal Constitution. The petition concerns only the question whether the Selangor State Legislative Assembly (SSLA) was authorized to enact section 66A of the ARIE 2003, conferring powers of judicial review on syariah (Islamic law) courts. The Court concluded that Selangor, a Malaysian state, cannot grant syariah courts the power to review the rulings of Islamic authorities, which is a power retained exclusively by civil courts.
