Warisan vice-president Terrence Siambun said Malanjum was a distinguished Sabahan with an exceptional track record which displayed his commitment to justice and unity.
In a statement, Siambun said the retired judge was the first East Malaysian to ever become the nation’s top judge.
“His highest achievement thus far is as Ombudsman of the United Nations Security Council.
“With his unparalleled legal expertise, commitment to justice and dedication to the wellbeing of all Sabahans, he is an exemplary candidate for this esteemed role.
“His tenure (as chief justice) was marked by respect for Malaysia’s constitutional framework, including the recognition of Islam as the religion of the federation, while safeguarding the rights of all communities.
“This proposal does not in any way jeopardise the position of Islam in Sabah. As guaranteed by the Federal Constitution, Islam’s status as the religion of the federation remains intact and respected,” he said in a statement.
He added that having Malanjum as governor would reflect Sabah’s identity as a harmoniously diverse state and would further foster unity.
The tenure of the current Sabah governor Juhar Mahiruddin expires at the end of the year. A former Kinabatangan MP from Umno, Juhar has been the Bornean state’s governor since 2011.
Last week, chief minister Hajiji Noor said he will submit the names of potential Sabah governor candidates to the Yang di-Pertuan Agong soon.
Malanjum was the first East Malaysian to be named as head of the Malaysian judiciary after Pakatan Harapan took control of the federal government in 2018. He retired in April 2019.
During the 2020 Sabah state election, Malanjum campaigned for the Warisan Plus coalition, which at the time comprised Warisan and Pakatan Harapan.
His name had also appeared on a purported list of state election candidates to be fielded by Warisan. The list was widely circulated on social media, giving rise to talk that he might contest a state assembly seat as a Warisan candidate at the time.
From 2006 to 2018, Malanjum served as Chief Judge of Sabah and Sarawak. Prior to that he was a judicial commissioner, a judge at the High Court of Sabah and Sarawak, in the Court of Appeal, and subsequently in the Federal Court.
