On polling day, the entire system narrows down to one simple act: a voter marks a single ballot paper inside a quiet room. Everything around that act — the electoral roll, the constituency boundaries, the body that counts the votes — is the constitutional framework that determines who may mark that paper, where, and how one pencil mark becomes a seat.

This page describes that framework descriptively and according to the constitutional text: how votes are counted, who is eligible, who administers elections, and the procedural sequence from dissolution to the result. It does not refer to any particular party, candidate or outcome.

One seat, one member, most votes wins

The starting point is not the number of voters, but the shape of the constituency. Article 116(2) provides that “the number of constituencies shall be equal to the number of members so that one member is elected for each constituency.” Each constituency returns one representative — no more.

Because each constituency elects only one person, the method of choosing becomes simple: the candidate who wins the most votes in that constituency wins. No absolute majority of fifty per cent is required, and there is no second round. This single-member plurality system is commonly called first-past-the-post (FPTP). The Constitution sets out its structure; the method of counting the highest number of votes itself is set out in election law such as Akta Pilihan Raya 1958, which is referred to in the official notes to Article 113.

Article 117 copies the same form to the state level. For the election of members of a State Legislative Assembly, the state is divided into “as many constituencies according to the number of members to be elected so that one member is elected for each constituency.” The federal and state structures are the same; only the chamber being filled differs.

Two chambers elected on the same day

Malaysia elects two levels of representative through a similar plurality vote.

• Dewan Rakyat. The lower house of the federal Parliament, with 222 seats set out in Article 46. Each seat is one federal constituency under Article 116.
• State Legislative Assembly (DUN). Each state has its own legislative assembly, with a number of seats fixed by its own state constitution and divided under Article 117.

In most states, the state election is held at the same time as the federal general election. Article 113(2) reinforces this alignment by requiring that the boundary review for state constituencies be conducted “at the same time” as the review for the Dewan Rakyat. A voter in such a state typically receives two separate ballot papers on the same day: one for Parliament, one for the DUN.

Some Peninsula states choose to dissolve their DUN at a different time, producing a state election separate from the general election. This lies within the jurisdiction of the respective state.

Who may vote

Article 119(1) sets three conditions that must all be met at once. A citizen is entitled to vote if he or she:

1. has reached the age of 18 on the qualifying date;
2. is resident in a constituency on that date, or is registered as an absent voter; and
3. is registered on the electoral roll for the constituency in which he or she is resident.

The age of 18 is the current position following the constitutional amendment commonly known as Undi18 — Akta Perlembagaan (Pindaan) 2019, which lowered the voting age from 21 to 18. The same amendment introduced automatic voter registration, under which eligible citizens are entered on the electoral roll by the Election Commission without needing to apply separately.

Article 119(1) also sets one important limit: “no person shall vote in the same election in more than one constituency” — one person, one vote for each chamber.

Article 119(3) lists the grounds for disqualification as a voter: being detained as a person of unsound mind or serving a sentence of imprisonment on the qualifying date; or having been convicted of an offence and sentenced to death or to imprisonment exceeding twelve months and still liable to serve that sentence.

The Election Commission: the body that runs elections

Elections do not run themselves. Article 113(1) establishes the Election Commission (Suruhanjaya Pilihan Raya, SPR) and gives it two core tasks: conducting elections to the Dewan Rakyat and the State Legislative Assemblies, and preparing and reviewing the electoral roll.

Article 114 sets out the body’s composition and independence.

Feature	Provision
Membership	A chairman, a deputy chairman and five other members — seven persons (Article 114(1))
Appointment	By the Yang di-Pertuan Agong after consulting the Conference of Rulers (Article 114(1))
Consideration	The Agong shall have regard to the importance of securing an Election Commission that enjoys public confidence (Article 114(2))
Retirement age	66 (Article 114(3))
Removal	Only on the like grounds and in the like manner as a judge of the Federal Court (Article 114(3))
Remuneration	Charged to the Consolidated Fund; may not be altered to a member’s disadvantage after appointment (Article 114(5), (6))

This design gives the Election Commission some of the same shields of independence as the judiciary: an appointment process that involves the Conference of Rulers, security of tenure through strict removal conditions, and a salary protected from the Consolidated Fund so that it does not depend on an annual vote.

Delimitation: how constituency boundaries are set

Because each constituency returns one member, where the boundary lines are drawn determines which voters are grouped together. Article 113(2) gives the Election Commission the task of reviewing the division of the Federation and the States into constituencies, and recommending changes so that the provisions of the Thirteenth Schedule to the Constitution, which contains the principles that must be followed, are complied with.

Two time limits govern this cycle:

• Minimum interval of eight years. Article 113(2)(ii) sets an interval of not less than eight years between the date a review is completed and the date the next review begins.
• Completed within two years. Article 113(2)(iii) requires each review to be completed within a period not exceeding two years from the date it begins.

Article 113(6) requires separate reviews for the States of Malaya, for Sabah, and for Sarawak — each treated as its own distinct “review unit.” The Election Commission’s report of recommendations is submitted to the Prime Minister, and boundary amendments must be approved by the Dewan Rakyat before taking effect.

When an election is called

A general election does not occur on a fixed date. It is triggered by a dissolution. Article 55(3) provides that Parliament runs for five years from its first sitting and then stands dissolved of itself, unless dissolved earlier by the Yang di-Pertuan Agong under Article 55(2).

As soon as Parliament is dissolved, the constitutional clock starts. Article 55(4) sets two limits:

Event	Time limit after dissolution
General election held	Within 60 days
Parliament summoned to meet again	Not later than 120 days

For an unscheduled vacancy of a seat between general elections, a by-election may be held under Article 54 — although a proviso to Article 54 exempts a vacancy arising within two years before Parliament is due to be dissolved, in certain circumstances.

The course of an election

After a dissolution, the Election Commission sets the same procedural sequence for every election. The Election Commission’s official portal describes its stages as follows.

1. Issue of writ. The Election Commission issues a writ — an instrument of authority — to the Returning Officer for each constituency to conduct the election, and fixes the date of nomination and the date of polling.
2. Nomination day. On the fixed date, the Returning Officer receives nomination papers from candidates together with a proposer and a seconder.
3. Campaign period. Once nomination is complete, candidates and their representatives may campaign. Campaigning must stop exactly at midnight before polling day.
4. Polling day. Registered voters mark their ballot papers at the polling stations fixed for their constituency.
5. Counting of votes. Ballot papers are counted after polling closes.
6. Declaration of result. The candidate who wins the most votes in each constituency is declared the winner by the Returning Officer.

The exact details — nomination hours, campaign period and candidate deposit — are governed by Akta Pilihan Raya 1958 and the regulations made under it, and may change; current figures should be checked against the Election Commission’s official announcements for each election.

From seats to government

Votes elect members; those members then determine the government. Article 43(2)(a) provides that the Yang di-Pertuan Agong shall appoint as Prime Minister a member of the Dewan Rakyat who, in his judgment, is likely to command the confidence of the majority of the members of that House. The plurality voting system determines the composition of the Dewan Rakyat; Article 43 then determines who governs based on that House’s confidence. The detail of this path is described in Dewan Rakyat and Parliament of Malaysia.

Common mistakes

“A candidate must win with a 50 per cent majority.” No. Under the plurality voting system shaped by Article 116(2), the candidate with the highest number of votes wins even if this is less than half of the total votes, and there is no second round.

“A vote directly elects the Prime Minister.” Voters elect only the member for their own constituency. Article 43(2)(a) leaves the appointment of the Prime Minister to the Yang di-Pertuan Agong, based on the confidence of the majority of the Dewan Rakyat.

“The voting age is 21.” Article 119(1) now sets it at 18, following the amendment through Akta Perlembagaan (Pindaan) 2019.

“The Election Commission is part of the ordinary government.” Article 114 gives its members security of tenure like judges, remuneration from the Consolidated Fund, and an appointment process involving the Conference of Rulers.

“Boundaries can be changed at any time.” Article 113(2) sets an interval of not less than eight years between one delimitation review and the next.

What’s next

To understand the chamber filled by this election and how seats become law, read Dewan Rakyat and Parliament of Malaysia. The role of the Yang di-Pertuan Agong in the dissolution of Parliament and the appointment of the Election Commission is described in Yang di-Pertuan Agong and Conference of Rulers. For the structural document that sets out all the provisions above, read Federal Constitution.
