Constitutional Review of Dual Office Holding by Party Chairpersons: MK 257/PUU-XXIV/2026

The Constitutional Court of the Republic of Indonesia registered case 257/PUU-XXIV/2026 as a material review of Law Number 2 of 2011, which amended Law Number 2 of 2008 on Political Parties. The applicants, Adi Haryanto and Muhammad Rizki, challenged Pasal 2 ayat (1b) of that law, the provision that governs which positions the founders and administrators of a political party may hold at the same time. The decision record carries a date of 30 July 2026 and lists the applicants as law students appearing in their own name as citizens.

Legal Reasoning

The constitutional argument recorded in the decision turns on an omission rather than on the wording of an existing rule. Pasal 2 ayat (1b) bars the founders and administrators of a political party from holding concurrent membership in another political party. According to the record, it says nothing about whether the chairperson of a political party may at the same time occupy a strategic public office. The applicants characterised that silence as a gap in the norm, one that in their submission leaves no legal limit on the concentration of party power and governmental power in the same individual, and no safeguard against the conflict of interest they said follows from it.

The petition names Pasal 27 ayat (1) and Pasal 28D ayat (3) of the 1945 Constitution as its formal benchmarks, and its argument rests on two provisions. The first is Pasal 28D ayat (3) of the 1945 Constitution, which states that every citizen has the right to equal opportunity in government. The applicants read the absence of a dual office rule as narrowing that opportunity, because offices are said to accumulate in the hands of those who already lead parties. The second is Pasal 1 ayat (3), the provision declaring Indonesia a state based on law, from which the petition derives a requirement that every form of concentrated power be regulated and limited by law.

The record also sets out the institutional premise behind the claim. Political parties are described as occupying a strategic position in the Indonesian constitutional system because they serve as instruments of political participation, political education, political recruitment, and the filling of public offices. On that footing the petition argued that party governance cannot be separated from the principles of a law based state and constitutional democracy, both of which are said to require limits on power in order to prevent conflicts of interest and the misuse of authority.

On standing, the applicants asserted a constitutional loss that was actual or at least potential according to reasonable reasoning, and argued a causal link, described in the record by the term causal verband, between the operation of Pasal 2 ayat (1b) and that loss. They supported the claim with an annex listing sitting chairpersons of national political parties who concurrently hold executive office, offered as evidence that the provision does not regulate concurrent public office at all. The remedy sought was not annulment. The petition asked the Court for a conditionally unconstitutional reading under which the provision would be construed to bar the founders and administrators of a political party from concurrent membership in another party and to bar a party chairperson from concurrently serving as President, Vice President, Minister, Governor, Deputy Governor, Regent, Deputy Regent, Mayor, Deputy Mayor, or in other public offices determined under legislation.

The Ruling

The operative part of the decision states: Menyatakan permohonan para Pemohon tidak dapat diterima. The application of the applicants is declared inadmissible.

The Court held that the applicants, who did not show that they were founders, administrators or members of any political party, had not established a causal link between Pasal 2 ayat (1b) and any actual or potential constitutional loss, and so lacked legal standing. A ruling in that form disposes of the case without the Court reaching the constitutionality of the provision that was tested. The record contains no order altering, annulling, or reinterpreting Pasal 2 ayat (1b), and no conditional construction of the kind the petition requested. The provision therefore continues to operate as enacted, limited to the prohibition on concurrent membership in another political party, and the question of concurrent public office remains unaddressed by that text. The decision record carries no dissenting opinion.
