government continued to make the annual "cession money" payment to the sultan and his heirs, and these payments were expressly shown in the receipts as "cession money". In a 1961 conference in London, during which a Philippine and British panel met to discuss the Philippine claim of North Borneo, the British panel informed the Philippine congressman, Jovito Salonga, that the wording of the receipts had not been challenged by the sultan or his heirs. During a meeting of Maphilindo between the Philippine, Malayan and Indonesian governments in 1963, the Philippine government said the sultan of Sulu wanted the payment of 5,000 from the Malaysian government. The first Malaysian prime minister at the time, Tunku Abdul Rahman, said he would go back to Kuala Lumpur and get on the request. Malaysia considers the amount an annual "cession" payment for the land, while the sultan's descendants consider it "rent". The foregoing Sulu claim rests on the treaty signed by Sultan Jamalul Alam of Sulu appointing Baron de Overbeck as Dato Bendahara and Raja Sandakan on 22 January 1878. However, a further, earlier treaty signed by Sultan Abdul Momin of Brunei appointed Baron de Overbeck as the Maharaja Sabah, Rajah Gaya and Sandakan. This was signed on 29 December 1877, and granted the territories of Paitan as far as the Sibuco River, which overlaps the Sulu Sultanate's claim of their dominion in Sabah. 1885 Madrid Protocol As attested to by the International Court of Justice in 2002, the Sultan of Sulu relinquished the sovereign rights over all his possessions in favour of Spain, based on the "Bases of Peace and Capitulation" signed by the Sultan of Sulu and the crown of Spain in Jolo on 22 July 1878. The Sultan declared beyond discussion the sovereignty of Spain over all the Archipelago of Sulu and the dependencies thereof. In 1885, the United Kingdom, Germany and Spain signed the Madrid Protocol to cement Spanish influence over the islands of the Philippines. In the same agreement, Spain relinquished all claims to North Borneo which had belonged to the sultanate in the past in favour of the United Kingdom. 1903 Confirmation of cession of certain islands On 22 April 1903, the successor of Sultan Jamalul Alam, Sultan Jamalul Kiram II, signed a document known as the "Confirmation of cession of certain islands", under which he grant and ceded additional islands, in addition to the land agreed upon
