There are two parallel justice systems: the common law system, presided over by the Supreme Court; and the Islamic system, presided over by the Syariah courts.
Common Law System
The Brunei Judiciary Department was established in 2002. It is responsible for the administration of Brunei's judicial matters.
The Supreme Court of Brunei is guided by the Constitution and Statutes in executing their responsibility. However, where there are no written laws on a particular matter, the courts turn to principles of law found in case law or judicial precedent. The decisions of higher courts are binding on the lower courts. Decisions from superior courts in comparable jurisdictions are persuasive but not binding on Brunei courts.
The Court Hierarchy - lowest to highest is:
Judges are appointed by the Sultan for three-year terms.
More information on each of the Courts is available from the Judiciary website under the About Judiciary heading. This website also provides information and guides for litigants and practitioners, practice directions, cause lists, hearing dates, case status, statistics, speeches, and judgments.
The Privy Council
In civil matters, final recourse is available through the Judicial Committee of Privy Council (JCPC) in the UK. The right to appeal to the Privy Council in Criminal matters was abolished in 1995.
The Judicial Committee of the Privy Council Practice Direction 1 notes that:
The legislation governing appeals to the JCPC is:
Syariah courts have jurisdiction over civil matters such as Islamic family, property and inheritance, as well as criminal law. The Syariah Courts in Brunei consist of the Syariah Subordinate Courts, the Syariah High Court and the Syariah Appeal Court. The jurisdiction, powers, duties and authority of these courts is conferred by the Syariah Courts Act (Chapter 184).
