The Council is made up of its Chairman (as of 6 November 2012 the Chief Justice of Singapore, Sundaresh Menon), up to ten permanent members who are appointed for life, and up to ten ordinary members who are appointed for a period of three years and may be re-appointed. Appointments are made by the President on the advice of the Cabinet. If the President does not concur with Cabinet's advice, he may veto appointments. However, he is required to consult the Council of Presidential Advisers ("CPA"), and if the CPA does not concur with his view, Parliament may override his decision with a resolution passed with a two-thirds majority vote. The President has no power to remove current PCMR members.
The Constitution only requires members of the Council to be Singapore citizens residing in Singapore who are at least 35 years old. There is no restriction on Cabinet ministers and members of political parties. Moreover, the Prime Minister may authorize any Minister, Minister of State or Parliamentary Secretary to attend Council meetings. It has been noted that this may have a chilling effect on the Council's deliberations as such a guest might be the author or a vocal proponent of the legislation under scrutiny. On the other hand, it has been suggested that members with political affiliations can often make the biggest contribution towards the Council's discussions. Another criticism of the PCMR's composition is that having judges on the Council may lead to a conflict of interest as they may have to exercise judicial review over Acts of Parliament they have either endorsed or rejected previously.
All proceedings of the Council are conducted in private, and the Council is prohibited from hearing objectors or examining witnesses regarding any bill or law under consideration. Since its establishment, the PCMR has not found any legislation to contain differentiating measures.
The Presidential Council for Minority Rights (PCMR) is a non-elected body established in 1970 under Part VII of the Constitution of the Republic of Singapore to fulfil the roles of safeguarding minority rights and advising the Government and the Parliament of Singapore. Its general function, as articulated in the Constitution, is "to consider and report on such matters affecting persons of any racial or religious community in Singapore as may be referred to the Council by Parliament or the Government". To fulfil its role as a safeguard against any parliamentary or executive propensity to majoritarian or sectarian politics, it may constrict the Government's freedom to discriminate against racial and religious communities by obstructing the passage of new laws and regulations that it deems to contain such "differentiating measures".
As a legislative review mechanism, it plays a "limited quasi Second Chamber" role. It has also been called "the closest body to a Second Chamber for many years". However, the Council has been criticized for lacking teeth to act as a real check on potential legislative abuses. As of 2009, the PCMR had not issued an adverse report regarding any piece of legislation referred to it. Nevertheless, it forms part of the statutory framework for the People's Action Party government's internationally lauded efforts in managing minority issues in multiethnic Singapore. Former Deputy Prime Minister S. Jayakumar, formerly a member of the Council, has noted that the PCMR is also a symbol of the paramount importance placed on racial harmony in a world still rife with racial and communal conflict.
