The Brunei Darussalam Supreme Court was established in 1963, replacing The Supreme Court of Sarawak, North Borneo and Brunei. The new Supreme Court consists of High Court and Court of Appeal with the same jurisdiction as the old Supreme Court. Since its establishment, the Supreme Court Building has been sited at various places including Kuala Belait. It has occupied a portion of old Secretariat Building and the old Lapau Building.
In 1978 the Government organized an architectural competition to design the new Supreme Court Building. The site selected for the building is bordered by Sungai Kedayan to the east and Jalan Tutong to the north. The construction of the building commenced in February 1981 and was completed in 1983. The building has a floor area of 96,500 square foot and was built at a cost of BND20 million. The opening ceremony of the Supreme Court Building was on 15th March 1984.
