How does an idea become a law in Cambodia, and who takes part? In short, a ministry usually writes it, the cabinet approves it, and both houses of parliament vote on it. The Constitutional Council may check it, and the King signs it.
What happened
Cambodia's Constitution says 3 groups can start a law: senators, members of the National Assembly, and the Prime Minister (Constitution, Article 91, OHCHR English translation). In practice, most new laws come from the government. The government's version is called a "draft law". A version started by lawmakers is called a "proposed law" (Open Development Cambodia, 2021).
- Step 1, drafting. The ministry in charge writes the text. Since 2013, Circular No. 03, an official government instruction, sets one common drafting method (Open Development Cambodia). Open Development Cambodia describes 2 rounds of consultation here, with ministries, local officials, civil society and businesses.
- Step 2, review inside the government. The Council of Jurists, a body of legal experts set up in 2020, checks the legal quality of the draft. Then the Council of Ministers, the cabinet, approves it in a full meeting (Law on the Council of Ministers, 1994).
- Step 3, the National Assembly. Members of the elected lower house debate the draft, can change it, and vote.
- Step 4, the Senate. The upper house has up to 1 month to examine the law, less if it is urgent. It can approve the law, suggest changes, or reject it. Suggested changes go back to the National Assembly, which decides whether to accept them (Constitution).
- Step 5, an optional check. For most laws this step is optional. The Constitutional Council may check if the law fits the Constitution. It must answer within 30 days (Constitution).
- Step 6, the King's signature. The King signs a Royal Kram, a royal act officially announcing the law. When the King is abroad, the Senate President signs as Acting Head of State. The law is published in the Royal Gazette, the official record of laws (Hap, 2022). It takes effect in Phnom Penh after 10 days and nationwide after 20 days. A law marked urgent takes effect at once (Constitution).
In a real example, on 13 March 2026, the cabinet approved a draft law against online scams (CamboJA News, 2026). On 30 March, the National Assembly passed it, 112 votes to 0 (Asia News Network, 2026). The Senate approved it on 3 April. On 6 April, the Acting Head of State signed it, and it took effect at once (Fresh News, 2026). That is 24 days from cabinet to law (our calculation).
Why it matters
Tax rates, traffic fines and business licences often come from rules below laws. Think of a pyramid (Council of ASEAN Chief Justices; Hap, 2022):
- Constitution.
- Law (chbab): passed by parliament, signed by the King.
- Royal decree (preah reach kret): signed by the King when the government asks.
- Sub-decree (anukret): adopted by the cabinet, signed by the Prime Minister.
- Prakas: issued by a minister, for that ministry's area.
- Decisions, circulars and deika: narrower instructions. Deika are local rules.
Each lower rule must follow the rules above it (Hap, 2022; Council of ASEAN Chief Justices).
Who is involved
- The National Assembly has 125 members, for the term that began in 2023. 17 are women, or 13.6% (IPU Parline, 2023). Each member speaks for about 139,392 people (estimate, our calculation: 17.424 million people divided by 125, IPU Parline 2023 data).
- The Senate has 62 members, for the term that began in 2024. 60 are chosen by indirect election, not directly by voters. 2 are appointed by the King. 12 are women, or 19.4% (IPU Parline, 2024).
- The Constitutional Council has 9 members. The King, the National Assembly and the Supreme Council of the Magistracy each name 3, for 9 years. The King, the Prime Minister, or the president of either house can send a law to it. So can 1/10 of Assembly members, or 1/4 of senators (Constitution).
Risks and open questions
Speed can help the state respond to urgent problems, like online scams. But it also leaves less time for the public to read a draft. In July 2025, the Constitution itself was changed, on citizenship. The Assembly voted on 11 July 2025, with 125 votes (Office of the Council of Ministers Press Unit, 2025). The Senate voted 3 days later, with 58 votes (AKP, 2025). It was signed the next day (Open Development Cambodia, 2025). That is 4 days from Assembly vote to signature (our calculation).
What it means for you
Knowing who signs a rule helps you know whom to ask. Citizens can also ask whether a law fits the Constitution. They do this through their representatives, senators, or the president of either house (Constitution).
Different views
On speed. Both recent examples passed with no votes against (Asia News Network, 2026; Office of the Council of Ministers Press Unit, 2025; AKP, 2025). Some see this as broad agreement on urgent issues. Others may ask if short timelines leave enough time for public reading.
On consultation, the government view. In October 2025, Cambodia's envoy spoke at the UN Human Rights Council. On the environment, he said Cambodia meets challenges "through law, consultation and reform". He said civil society joins "open forums twice a year" (Cambodianess, 2025). Businesses can raise problems through the Government–Private Sector Forum, running since 1999. Its latest report counts issues raised since November 2023. By the end of 2024, 115 issues had been raised and 79 were resolved, about 69%. These are the government's own figures (Council for the Development of Cambodia, 2025).
On consultation, other views. The UN Special Rapporteur, an independent expert, issued a report in 2025. On natural resources, it calls for more "localized participation and inclusivity". It also asks for "people-led checks and balances" (OHCHR, 2025). The legal group ICNL (International Center for Not-for-Profit Law) tracks draft laws that affect civil society. A draft Access to Information law has been discussed for years. As of August 2025, it had not been formally introduced (ICNL, 2025; CamboJA News, 2024).
About the data
- Legal rules come from one English translation of the Constitution, as amended in 1999 and hosted by OHCHR. Translations of the Khmer original differ slightly, so we do not give the Senate's urgent deadline.
- Membership counts come only from IPU Parline. People per member is our own estimate.
- The 24-day and 4-day timelines are our calculations from reported dates.
- The forum figures (115 raised, 79 resolved) are government-reported, not an independent audit. They cover issues raised from November 2023 to the end of 2024, not totals since 1999.
