Law, Sub-decree, Prakas: The Hierarchy of Cambodian Legal Documents Explained

When you read a Cambodian document, the first question is what kind of document it is. A law, a sub-decree and a prakas can all look official, yet they come from different authorities and carry different weight. This guide explains the main types in plain English, who issues them, and how they fit together.

The basic idea: each level rests on the one above

A fact sheet on the hierarchy of laws, published by the Cambodian Center for Human Rights, puts it simply: each legal instrument draws its validity from the instrument above it. A lower instrument must conform to the higher one, or it can be changed or invalidated. A Konrad Adenauer Foundation study says the same for sub-decrees and prakas, which must comply with the Constitution and with the law that authorises them.

Scholars arrange the details slightly differently, especially for treaties and for royal decrees versus sub-decrees, so treat the order below as a practical map rather than a legal ruling.

The levels, from top to bottom

Level	Issued by	Typical purpose
Constitution	–	Supreme law
Law (Chbab)	National Assembly and Senate, promulgated by the King	Main rules on a subject
Royal decree (Preah Reach Kret)	The King, on request of the Council of Ministers	Appointments; organising state bodies
Sub-decree (Anukret)	Prime Minister, after Council of Ministers approval	Detail for implementing laws
Prakas	A minister (or several jointly)	Ministry-level rules and procedures
Decision, circular	Prime Minister or ministers	Temporary measures; instructions
Local regulation (Deika)	Local councils	Rules within their own territory

Constitution

Article 150 of the Constitution calls it the supreme law and says laws and decisions of state institutions must strictly conform to it. Before a law is promulgated, designated officials can send it to the Constitutional Council for review, and a provision found unconstitutional cannot be promulgated or implemented.

International treaties

This is the least settled part of the map. The Konrad Adenauer study places treaties approved by the National Assembly and Senate above ordinary laws. The Cambodian Center for Human Rights notes that the Constitution recognises human rights treaties but does not clearly state where treaties sit in the hierarchy. If a treaty matters to your question, ask a qualified Cambodian lawyer.

Law

A law is passed by the National Assembly, reviewed by the Senate and signed by the King. The Constitution gives the King the role of signing the royal acts that promulgate laws. A law takes effect ten days after signing in Phnom Penh and twenty days after signing across the country, unless it is declared urgent. In citations, a law often appears together with the number of the Royal Kram that promulgates it, such as the Labour Law cited as Royal Kram CS/RKM/0397/01.

Royal decree

Royal decrees are signed by the King after the Council of Ministers submits them. An introduction to Cambodian law by Phalthy Hap describes two kinds: decrees that appoint or dismiss personnel, and executive decrees that enforce specific laws.

Sub-decree

Sub-decrees are the everyday tool of the Royal Government. They are drafted in ministries, approved by the Council of Ministers and endorsed by the Prime Minister. They typically clarify how a law works in practice or set the functions of government bodies. The same overview divides them into appointing sub-decrees and executive sub-decrees. A real example is Sub-Decree No. 182 ANK.BK of 2 December 2019 on municipal administrations. Its opening lines cite the Constitution, royal decrees, royal krams and earlier sub-decrees as its legal basis, which shows the chain of authority in action.

Prakas

A prakas is a ministerial proclamation. It implements higher rules within the issuing ministry’s own subject area and cannot go beyond that authority. Some are joint instruments signed by more than one ministry. Prakas are usually cited with a number, a ministry abbreviation and a subject, for example a Ministry of Commerce prakas on price tagging.

Circulars, decisions and local rules

Decisions are generally temporary measures. Circulars give instructions or explain how to read higher rules, and one source states that they are not legally binding. Local regulations bind only inside the territory of the council that approved them.

Common confusions

A royal decree and a sub-decree sound alike, but the first comes from the King and the second from the Prime Minister.
Ministries issue several kinds of paper, including prakas, circulars, decisions and notices. The type named in the title tells you how seriously to treat it.
English renderings vary. Prakas is also translated as proclamation or ministerial order, so rely on the Khmer title and the number.

Publication matters

Government norms of general effect must be published in the Royal Gazette, according to the study quoted above, and another overview says publication is needed for them to take effect. See our guide on finding official documents for where to look.

Practical tips for readers

Read the preamble. It names the legal basis, so you can trace the chain upward.
Check the title and number. The type is part of the citation.
Do not assume that a prakas or circular can override a law.
Check whether a newer instrument has amended or replaced the one you are reading.
