Formally established on the 3rd March 2003, Judge Advocate General’s Office began its journey in the Royal Brunei Armed Forces as a small unit formerly known as the ‘Military Legal Unit’ (MLU) under the purview of the Directorate of Personnel.   On 1 January 2021, as part of the review of its structure, JAG was effectively transferred under the Commander RBAF Secretariat Office.

As the principal legal advisor to the RBAF and Ministry of Defence, JAG plays a crucial role in providing guidance and legal advice in relation to discipline, administration, operation, training and policy to all RBAF Commanders and command holders as to allow them to make just and rational decisions and actions based on the Principles of Justice and due process in accordance with RBAF and National Laws.

JAG currently comprises 4 main divisions: Prosecution, Operations, Policy & Legislation, and General Advisory.  Whilst JAG as a whole, acts as the principal legal advisor to the RBAF and the Ministry of Defence (MINDEF) on all matters pertaining to law, each of these 4 divisions has distinct legal roles and responsibilities in the overall execution of JAG’s functions.   JAG is also the national legal Subject Matter Expert (SME) on Operational Law and Military Disciplinary Law matters.
