Administration

The Borneo States of Sabah and Sarawak joined the Federation of Malaysia as equal partners with Malaya and Singapore. Sabah and Sarawak retained their rights covered under the Malaysia Agreement of 1963 and their degree of autonomy compared to the other states in Peninsular Malaysia. For example, the Malaysian Borneo States have separate laws regulating the entry of citizens from other states in Malaysia (including the other East Malaysian state), whereas, in Peninsular Malaysia, there are no restrictions on interstate travel or migration, including visitors from East Malaysia. There are also separate

Apart from restoring Article 1(2) to its pre-1976 wording, the bill defines

With regard to the administration of justice, the courts in East Malaysia are part of the federal court system in Malaysia.

Politics

Compared to West Malaysia, political parties in Sarawak and Sabah started relatively late. This first political party in Sarawak emerged in 1959 while the first political party in Sabah emerged in August 1961.

. Sabah only held its first district council election in December 1962 and first direct election in April 1967. Both the states were new and had little experience in organised, competitive politics. Therefore, there had been the appearance and rapid disappearance of political parties in Sarawak and Sabah within a short period of time, with some parties took opportunistic moves to form alliances without a definite loyalty to a certain political alignment. The ethnic composition of East Malaysia is also different from West Malaysia. The indigenous people in both Sarawak and Sabah do not form an absolute majority, while the non-native population in East Malaysia mainly consisting of entirely Chinese. Political parties in Sarawak and Sabah were formed largely based on communal lines and can be categorised roughly into native non-Muslim, native Muslim, and non-native parties. With the support of the Malaysia federal government, native Muslim parties in Sabah and Sarawak were strengthened. In Sabah, the native Muslim party

In Sarawak, native Muslim party named Parti Bumiputera (which later regrouped into Parti Pesaka Bumiputera Bersatu (PBB) held the chief minister post since 1970. In 1976, all the Sabah and Sarawak MPs (except 4 absentees) supported the Malaysian parliament bill which downgraded both the states from being equal partners to Malaya as a whole, to one of the 13 states in the federation. Since 2008, East Malaysia played a more significant role in the national political landscape. The loss of two-thirds majority of

After the conclusion of 2013 Malaysian general election, there was an increase in ministers and deputy ministers allocation for East Malaysia in the Malaysian Cabinet from 11 out of 57 portfolios in 2008 election to 20 out of 61 portfolios. There had been no prime minister or deputy prime minister coming from East Malaysia until 2022, when Fadillah Yusof became the first deputy prime minister from East Malaysia.
