The legal frameworks and judiciaries of the Lower Mekong have been shaped by various historical influences in the region: internal and external conflicts, revolutions, and colonialism. Built around constitutions of varying age, the five countries have a similar structure of national through to local courts, and laws.
Along with political authority, each of the Lower Mekong states derives its legal authority from a national constitution. Several of the region’s constitutions were adopted or modified in recent years, reflecting fundamental changes in institutional structure, or in their systems of government. Thailand has had the most recent change (in 2014), and the most revisions to its constitution (13 including its original 1932 constitution and two interim constitutions in 2006 and 2014).
For each of the Lower Mekong states, the process of introducing, debating and passing laws follows three broad steps.
- Legislation can be introduced by members of the legislature. In Cambodia and Myanmar, this can include members of either the Senate or House of Representatives.
- Legislation must be approved by winning a majority vote in the legislative house, and in the senate where one exists, as is the case for Cambodia and Myanmar.
- Laws that have passed through the legislative branch of government are promulgated with the endorsement of the head of state. In Laos and Vietnam, this is the president; in Myanmar, the prime minister; and in Cambodia and Thailand, the king.1 2 3 4 5
Each of the five Lower Mekong countries have a similar hierarchical structure of legal forms, with a constitution as the supreme law, down to a limited administrative directive. Regional and local laws are then enacted at provincial and (in some cases) village levels for their jurisdictions. In 2007 Cambodia’s Constitutional Council stated that international treaties and conventions—once ratified—have the force of domestic law and may be the basis for judicial decisions.6 Generally, international treaties sit between a state’s constitution and laws in the legal hierarchy, but implementing legislation is generally deemed necessary to make the provisions of such agreements effective and enforceable.

The constitutions of all Lower Mekong countries call for judiciaries to be independent and impartial.8 In Laos, all judicial appointments (except the President of the People’s Supreme Court) are made on the recommendation of the President of the People’s Supreme Court. One notable exception is that Thailand’s interim constitution places the Constitutional Court subject to the Leader of the ruling National Council for Peace and Order.9
The heads of state of all countries are involved in appointing the chief justice of the country, and some are involved in the appointment of all judges. Generally speaking, these nominations must be approved by the national assembly.
Justice systems are relied on to adjudicate criminal charges and resolve disputes. With this in mind, essential judicial characteristics include integrity, independence (not being subject to external influences) and efficiency, reaching a decision in a reasonable time, without undue cost to the parties. Judicial systems are also key components of a state’s rule of law. Using a set of indicators from international index-based reports provides some opportunity to examine, and compare, the strength of the judicial systems of the five Lower Mekong states. However data on Laos were not available through two of the three reports we use here.
The four remaining Lower Mekong countries received scores ranking them in the bottom 50 percent globally for adherence to the rule of law, in the World Justice Project’s 2015 Rule of Law Index. They also ranked in the bottom five countries for the Asia Pacific region, as shown in the chart below. All four countries’ best scores came for “Order and Security” indicators. While Cambodia’s lowest scores were for indicators under “Absence of Corruption”, Vietnam’s lowest scores were for “Regulatory Enforcement”, and both Myanmar and Thailand scored lowest for “Criminal Justice”.10
Transparency International’s 2013 Global Corruption Barometer includes one indicator dealing with the reported frequency of bribes paid, and another for the percentage of respondents viewing the judiciary as corrupt or extremely corrupt. High numbers of respondents in both Vietnam (53 percent) and Cambodia (60 percent) viewed their judiciary as corrupt or extremely corrupt, however only 14 percent of people in Vietnam reported paying bribes to the judiciary, as opposed to 65 percent in Cambodia. Of Thailand’s respondents (the only other Lower Mekong country included in the report) 18 percent viewed the judiciary as corrupt or extremely corrupt, and 14 percent reported paying bribes to judiciary members.11
While the Doing Business Report is not about judicial institutions, it is about business activities and the regulatory and practical burdens placed on them by government. One activity is the enforcement of a claim under a contract. The efficiency of a state’s courts in resolving the case is measured in two ways:
- the time between filing and enforcement; and
- the cost of the process, in terms of the percentage of the claim being litigated.
As can be seen in the case of Cambodia’s data shown in the chart below, it is possible for the cost to exceed the value of the claim.12
While all countries now have the equivalent of a bar association that registers and oversees the practice of the legal profession in their country, some are not independent and accordingly exercise less oversight or control of the profession. In Cambodia and Laos, the bar associations administer, regulate and monitor conduct of lawyers.13 14 The Independent Lawyers’ Association of Myanmar, launched in 2016, is the first stage of establishing an independent bar association in the country.15 In Thailand, the Lawyers Council oversees the profession and is separate from the Thai Bar Association, which oversees legal education standards and legal aid.16 While Lawyers in Vietnam answer to their local bar associations, these are affiliated with the national Vietnam Lawyers’ Association, which is part of the Communist Party’s Vietnam Fatherland Front.17
There are 286 prisons in the Lower Mekong, housing more than 500,000 inmates. Prisons in Cambodia, Myanmar and Thailand—the only lower Mekong countries with statistics available on official prison capacity—all suffer from overcrowding. While Thailand had more than 100,000 prisoners over its official capacity in 2016, both Cambodia’s and Myanmar’s prison numbers were at more than double their capacities.
Cambodia had by far the highest percentage of pre-trial and remand detainees in the Lower Mekong, at 69.1 percent of their prison population in 2016. Myanmar (10.8 percent), Vietnam (17.5 percent) and Thailand (18.1 percent) all had similar levels of pre-trial/remand detainees, while data for Laos were only available from 2004, at 1 percent.18
All Lower Mekong countries support the concept of legal aid for their citizens, and all—with the exception of Myanmar—have established legal aid resources operating through government and donor funds.19 Myanmar adopted a law in 2016 creating an institutional, conceptual and legal framework for the provision of legal aid services, however with no budget allocation for any such services as of April 2016.20
