Over the years, Sultan Sulu`s heirs finally met with President Corazon Aquino, who advised them to organize themselves. In 1966, she wrote to the Malaysian Prime Minister asking him to increase the rent. However, Malaysia argues that in 1989, Sultan Sulu`s heirs withdrew their authorization granted to the Philippine government as a representative. In 2001, another heir sent another letter of debt for an increase in rents. In 1759, a Scottish sailor – Alexander Dalrymple – reached the Sea of Sulu. In 1877, a private union or private company received fomented subsidies from the sultans of Brunei and Sulu. In 1878, Sultan Sulu committed an act of pajak with an Austrian named Gustavus Baron of Overbeck and an Englishman named Alfred Dent as a representative of a British society. The act – that is, a written instrument that arouses some interest in property – was written in Arabic. In 1946, Professor Harold Conklin translated the term pajak into “lease.” The 1878 deed provided for an annual lease.
This contract of Pajak was signed by Sultan Sulu and the Consul General of Great Saxony. This contract is the main basis for the territorial dispute between the Philippines and Malaysia over Sabah. The 1878 agreement was written in Malay with Jawi`s writing, in which the contentious formulations are: a state may acquire sovereignty over a particular territory if sovereignty is transferred or ceded from the sovereign to another. If the British version of the 1878 treaty is adopted, it is clear that sovereignty over Sabah was transferred in 1878 from the Sultanate of Sulu to the British, who then transferred sovereignty over Sabah to Malaysia. However, since the creation of the Malaysian Federation in 1963, the Philippines has refused to recognize Malaysia`s possession of Sabah. The Philippines maintains its assertion that Overbeck and Dent transferred the rights only to the lease and not to Sabah`s sovereignty, as it was a private transaction. The dispute over northern Borneo, also known as the Sabah dispute, is the territorial dispute between Malaysia and the Philippines over much of the eastern part of Sabah state. Sabah was known as North Borneo before the creation of the Malaysian association. The Philippines, which presents itself as the successor state of the Sultanate of Sulu, retains a “sleeping right” east of the Absah on the basis that the territory was not leased to the British North Borneo Company until 1878, as the sovereignty of the sultanate (and later the Republic) over the territory was never abandoned.  However, Malaysia regards this dispute as a “non-subject” since it interprets the 1878 convention as the 1878 convention as the surrender agreement and considers that the inhabitants of Sabah (including eastern Abah) exercised their right to self-determination when they joined the Malaysian Federation in 1963.  On 22 January 1878, the Sultanate of Sulu and a British trade union consisting of Alfred Dent and Baron of Overbeck signed an agreement which, according to the translation used, provided that the North-Borneo be transferred to the British Union, or for a payment of 5,000 Malaysian dollars per year to the British Union.  On 15 July 1946, the North Borneo Cession Order in Council in 1946 declared borneo State to be attached to the British crown, becoming a British colony.
