This first issue of Harvard Law School’s Journal in Islamic Law Forum focuses on a new development in Islamic legislation that has generated much international media attention but little close analysis: Brunei’s new Islamic criminal code. The two main parts of the code are the Syariah Penal Code Order (SPCO) of 2013, which took effect in 2014, and the Syariah Courts Criminal Procedure Code Order (SCCPCO) of 2018, which took effect in 2019. With a foreword by Intisar A. Rabb, the Forum features contributions from three scholars and practitioners with expertise in Islamic criminal law, Southeast Asian history and society, and international law and foreign affairs from within Brunei: Mansurah Izzul Mohamed, Dominik M. Müller, and Adnan A. Zulfiqar. These three essays assess the history, workings, and critiques of Brunei’s new Code. This Online Companion provides the text of the series of laws forming the new Code, as well as its antecedents from British law.
