This restriction is contained in Section 66 of the Immigration Act 1959/63 and was included for MA63. Under the Malaysian agreement signed between Great Britain and the Federation of Malaya, Britain would adopt an act to abandon sovereign control of Singapore, Sarawak and North Borneo (now Sabah). This objective was achieved by the passage of the Malaysia Act of 1963, Article 1 (1) stipulates that, on the day of Malaysia, “Her Majesty`s sovereignty and jurisdiction over the new States must be abandoned in order to exist in the agreed manner.”  On 11 September 1963, just four days before the creation of the new Malaysian Federation, the Kelantan State Government requested a declaration that the Malaysian agreements and the Malaysia Act were null and void or that they would not engage the State of Kelantan, even if they were valid. [after whom?] [Citation required] Kelantan`s government argued that both the Malaysian agreement and the Malaysian Act were not binding on Kelantan, given that Malaysian law had in fact abolished the Malaya Federation and that this was at odds with the Malaya Federation of 1957, that the proposed amendments required the agreement of each of the constituent states of the Malaya Federation, including Kelantan, and that this had not been done. [Citation required] This agreement is the Malaysian agreement of 1963 (MA63), which sets out the conditions under which the three states agreed to merge the Malaya Federation in Malaysia: Sabah and Sarawak were not included. Indeed, this accession took place later, when another agreement was signed, which led to the merger between Sabah, Sarawak and, in short, Singapore and the Malaya Federation, with the current malaysian federation. Section 66 (1), Immigration Act 1959/1963 (partly): signatory to the Malaysian Agreement, which arrived in London on 12 July 1963. Image of the Borneo Office. The Malaysian agreement or the Agreement on Malaysia between the United Kingdom of Great Britain and Northern Ireland, the Federation of Malaya, North Borneo, Sarawak and Singapore was the agreement that linked Borneo, Sarawak and Singapore to the existing states of the Malaya Federation, the resulting Union and the name of Malaysia.
  Singapore was subsequently expelled from Malaysia and became an independent state on 9 August 1965.  This step is likely the result of Sarawak`s request to postpone implementation until July to a later date, which was rejected. It is interesting to note, however, that sarawak`s Minister of State for Tourism, Datuk Abdul Karim Rahman Hamzah, said that tourism was an issue that needed to be discussed under the 1963 Malaysian Agreement: the Malayan Union was founded by British Malaya and included the Federated Malay States, Perak, Selangor, Neger Sembilan, Pahang; the unfederated Malay states of Kedah, Perlis, Kelantan, Terengganu, Johor; and the streets of Penang and Malacca.
