The mandate of the International Affairs Division is premised on the general powers of the Attorney General as provided by Article 81 (2) of the Constitution, which states:

“The Attorney General shall advise on all legal matters connected with the affairs of Brunei Darussalam referred to him by His Majesty the Sultan and Yang Di-Pertuan or by the Government of Brunei Darussalam”


The Mission Statement of the International Affairs Division is:

To deliver the highest quality legal service through the effective interpretation and application of international law


The International Law Division, as it was known then, was established in 1996 with only 6 officers. Before 1996, international legal advisory matters were generally delegated to a few identified officers of the Attorney General's Chambers. YM Pengiran Hajah Zabaidah binti Pengiran Haji Kamaludin was instrumental in the establishment of the Division and was the first Head of the Division. In 2001, YM Pengiran Kasmirhan Bin Pengiran Haji Tahir was appointed as Head of the Division and was later followed by YM Hjh Dayang Nor Hashimah Binti Haji Mohd. Taib in 2006 as the Head of the Division and in 2011 she also became the Assistant-Solicitor General for the Division. In 2013, YM Dayang Elma Darlini Binti Haji Sulaiman was appointed as the Deputy Head of the Division in order to assist the Head of the Division on administering matters relating to international law as well as the management of the Division.

As of 1st February 2018, YM Datin Hajah Hasnah Binti Haji Ibrahim was appointed as Assistant-Solicitor General for the Division and Dayang Elma Darlini was appointed the Head of the Division.

Since its establishment, the work and, simultaneously, the specialisation of the Division in the areas of international law have grown. To reflect this, the name of the Division was changed to the International Affairs Division (or IAD) from 1st May 2007.
