Article 2 of Bahrain's 2002 Constitution as originally adopted, as well as after February 2012 amendment, declares Islamic Sharia is a chief source of legislation.[1][96] Four tiers of ordinary courts have jurisdiction over cases related to civil, administrative and criminal matters, with Court of Cassation the highest civil court in Bahrain; in all matters, the judges are required to resort to Sharia in case legislation is silent or unclear.[96] Sharia courts handle personal status laws.[97][98]
