The office of the Chief Judge of Sabah and Sarawak (formerly Borneo) is situated in the Kuching Courts Complex at Petra Jaya Kuching. It is the regional headquarters of the High Court of the two Borneo States.

The Chief Judge is in charge of all the Judges of the High Court in the 2 Malaysian Borneon States of Sabah and Sarawak, as well as of all Judicial and Legal Officers in the High Court, Sessions Courts and Magistrates Courts.

Like his counterpart in High Court in Malaya, the Chief Judge is also a senior member of the highest Court, the Federal Court which sits throughout the country to hear cases in that Court.

He also performs certain constitutional functions and ceremonies like the witnessing of the appointments of the Governors in the two States.

In Sarawak, the role of admitting new advocates to the Local Bar and the granting of ad hoc licences to non-Sarawakian lawyers to practise in the State is usually reserved for the Chief Judge. In Sabah this function is usually exercised by the most senior High Court Judge in that State.

Administratively, the Chief Judge, like his counterpart in Malaya, answers directly to the Chief Justice of the Federal Court in Putrajaya.

The current Chief Judge of Sabah and Sarawak is The Right Honourable Dato' Richard Malanjum, S.P.S.K.,S.I.M.P.,P.G.D.K (Profile)
