After the death of Sultan Jamalul Kiram II in 1936, who was childless, his brother Datu Mawallil Wasit succeeded him to the throne. Prior to his assumption, he was the Crown Prince or Raja Muda of Sultan Jamalul Kiram II. However, his succession has only lasted for six months.

When the Official of the British North Borneo Company held pending its release of agreed yearly rental, the legal heirs filed a petition to the High Court of North Borneo in the Form of Interpleader Suite. On October 11, 1939, the High Court of North Borneo issued a Grant of Letter of Administration to Datu Punjungan Kiram, appointing him as the Administrator of the State of North Borneo; copy of which hereto attached and made as an integral part of this Progress of the Sultanate Movement. Likewise, on December 11, 1939, a decision was promulgated naming the Nine (9) Rightful Principal Heirs, namely:

1. Dayang-Dayang Hadji Piandao Kiram
2. Dayang-Dayang Tarhata Kiram
3. Dayang-Dayang Sakinul In Kiram
4. Dayang-Dayang Sitti Rada Kiram
5. Dayang-Dayang Putli Jahara Kiram
6. Dayang-Dayang Sitti Mariam Kiram

8. Datu Punjungan Kiram - Administrator of the State of the North Borneo and father of the present Sultan
9. NAPSA MORA or NAPSA LAGAYAN, Mother of Datu Punjungan Kiram and wife of Datu Raja Muda Mawallil Wasit

Said decision, popularly known as Maskaskie Judgment, clearly emphasized on the government of the State of North Borneo's recognition and respect of the proprietary rights of the Sultan of Sulu over the State of North Borneo and the resumption of the continuing yearly rental to the heirs and would be heirs up to the present date.
