Abstract: Law, including Islamic law, will evolve with the changes of time, place, situation and tradition. New social problems grow gradually and pose challenges to Islamic law. Reconstruction and reform are inevitable for Islamic law to respond to the current issues. The Islamic law reforms in Indonesia performed through legal enactment, legal opinion (fatwa), and the Religious Courts decisions. New formula for Islamic law in addressing contemporary issues can be built through three processes: conservation, innovation process, and creation. The Supreme Court of the Republic of Indonesia fully supports the development of Islamic law in Indonesia. The reform of Islamic law by the Supreme Court has been carried out through several instruments, such as the issuance of Perma and SEMA, agreement among justices within the Chamber of the Religious Courts, and creation of jurisprudence.Abstrak: Hukum, termasuk hukum Islam, akan berubah seiring dengan perubahan waktu, tempat, situasi dan tradisi.
