The short answer
Sabah’s rotation system was a BN coalition agreement, not a constitutional requirement. After the 1994 change of government, the chief-ministership was meant to move every two years among Muslim-bumiputera, Chinese and non-Muslim-bumiputera leaders. Six officeholders served before Musa Aman’s 2003 appointment ended the scheduled sequence.

A timeline of the turning points
PBS wins the Sabah election 25–23
Joseph Pairin Kitingan formed a government with the narrowest possible elected majority.
Defections install a BN government
Pairin resigned after losing assembly support and Sakaran Dandai became chief minister.
Salleh Said Keruak begins the first full phase
Sakaran moved to the state headship and Salleh represented the Muslim-bumiputera category.
Yong Teck Lee takes the Chinese-community phase
The SAPP president served for two years before the next scheduled transfer.
Bernard Dompok represents non-Muslim bumiputeras
The PDS president took office, but the coming state election cut his phase short.
BN wins the state election
Dompok lost his state seat as PDS won only two constituencies, ending his term after about ten months.
Osu Sukam returns the office to UMNO
The Kawang assemblyman began another Muslim-bumiputera phase and served for two years.
Chong Kah Kiat begins the final rotation phase
The LDP president became chief minister under Article 6(3) of the Sabah Constitution.
Musa Aman succeeds Chong
Musa’s appointment ended the sequence of planned two-year community transfers.
Musa remains after the election
His retention confirmed that BN had replaced rotation with continuing leadership based on coalition and assembly support.
What was Sabah’s chief minister rotation system?
The rotation system was a Barisan Nasional power-sharing arrangement used after the coalition took control of Sabah in March 1994. The chief-ministership was intended to move every two years among leaders identified with three broad categories: Muslim bumiputeras, Chinese Sabahans and non-Muslim bumiputeras, especially Kadazandusun-Murut communities.
It was a coalition formula rather than a rule requiring every Sabah government to rotate its leader. The state constitution continued to provide for the Yang di-Pertua Negeri to appoint the assembly member likely to command majority confidence. Rotation determined whom BN would support for appointment while it held that majority.
The practical sequence ran from Sakaran Dandai’s short transitional administration through Salleh Said Keruak, Yong Teck Lee, Bernard Dompok, Osu Sukam and Chong Kah Kiat. Musa Aman’s appointment in March 2003 ended the scheduled transfers, and his retention after the 2004 election confirmed the system’s abandonment.
Why was the system introduced after the 1994 crisis?
PBS won the February 1994 state election by 25 seats to BN’s 23. Pairin formed a government, but elected members crossed to BN-aligned parties within weeks and removed his majority. Sakaran then became chief minister at the head of a coalition assembled after polling.
BN needed to hold together UMNO and smaller parties representing communities that had previously supported PBS. Academic accounts describe rotation as a way to promise access to the top office while UMNO consolidated its new position as Sabah’s largest governing party.
The formula also answered a long-running problem in Sabah coalition politics: no single party could easily claim to represent the state’s religious, ethnic and regional diversity. A scheduled transfer offered symbolic inclusion without requiring BN to surrender overall control of government.
How did the two-year rotation work?
Each designated leader was expected to serve about two years before resigning so that the governor could appoint the next BN choice. The cabinet and assembly did not dissolve at every transfer; the coalition majority continued while the person at its head changed.
Sakaran’s March–December 1994 administration came before the first full two-year phase. Salleh then represented the Muslim-bumiputera category, Yong the Chinese category and Dompok the non-Muslim-bumiputera category. Osu and Chong began a second cycle for the first two categories.
This structure differed from an election mandate. Voters elected assembly members, not a chief minister for a fixed popular term, and the constitutional appointment still depended on confidence in the assembly. BN’s internal agreement supplied the timetable that the constitution itself did not specify.
Why did Bernard Dompok serve only ten months?
Dompok became chief minister on 28 May 1998 and was expected to represent the non-Muslim-bumiputera phase. Sabah then held a state election in March 1999, before his intended two years had elapsed.
PDS won only two seats and Dompok lost his own state constituency. Osu Sukam, an UMNO leader who retained Kawang, became chief minister after BN returned to government. Electoral performance therefore interrupted the rotation timetable.
The unequal result became a central criticism of the arrangement. The Muslim-bumiputera and Chinese categories received repeated or complete two-year phases, while Dompok’s roughly ten months were the only period led by the designated non-Muslim-bumiputera representative.
Did rotation create equal power among the communities?
Rotation distributed the title of chief minister, but it did not distribute every source of political power equally. UMNO remained the largest party within the BN government and retained substantial influence over coalition support, cabinet formation and relations with the federal leadership.
Smaller parties gained visibility and access to the premiership, yet their leaders served within a coalition whose legislative centre of gravity remained with UMNO. James Chin’s analysis argues that the formula helped secure non-Muslim participation while UMNO consolidated control of the state government.
The shortened Dompok term also showed that equal two-year blocks were not guaranteed. Rotation was therefore a negotiated mechanism of inclusion, not evidence that the three community categories exercised identical authority or received identical time in office.
Why did Sabah end the rotation system?
By 2003 the repeated transfers had produced six chief ministers in nine years. Supporters saw community representation; critics argued that a two-year horizon was too short for consistent administration and made succession depend heavily on bargaining inside BN.
Chong completed the final scheduled phase in March 2003 and Musa Aman was appointed chief minister. BN did not transfer the office to another community leader two years later. Instead, Musa remained after the 2004 election and ultimately served for fifteen years.
It is therefore clearest to distinguish the operational endpoint from later descriptions of formal abolition: the planned sequence ended with Musa’s appointment in 2003, while his continuation after the 2004 election made the policy change unmistakable.
What is the rotation system’s legacy?
The arrangement remains one of the most distinctive experiments in Malaysian state government. It acknowledged that Sabah’s coalition had to cross several community and party lines, but it did so by assigning the top office through broad identity categories.
Its history also connects two debates that still shape Sabah: whether regional parties or national parties should lead the state, and how power-sharing can reflect diversity without reducing political representation to a fixed communal formula.
Later administrations did not restore scheduled rotation. Sabah instead returned to the normal confidence principle: the governor appoints the assembly member judged likely to command a majority, and that leader continues while political and legislative support holds.
