Government of Thailand

This article is part of a series on the
politics and government of

The Government of Thailand, or formally the Royal Thai Government (RTG) (Thai: รัฐบาลไทย; RTGS: Ratthaban Thai), is the unitary government of the Kingdom of Thailand. Thailand has been a constitutional monarchy under a parliamentary democracy system since 1932. The country has existed in some form since the 13th century, but the country emerged as a modern nation state after the foundation of the Chakri Dynasty and the city of Bangkok in 1782. The Revolution of 1932 brought an end to absolute monarchy and replaced it with a system of constitutional monarchy.

From then on the democratic system has been weak and the country was ruled by a succession of military leaders installed after coups d’etat, the most recent in May 2014. Under the 2007 Constitution (drafted by a military appointed council, but approved by a referendum) the present structure of the Government of Thailand was established.

Thailand has so far had seventeen Constitutions; however the basic structure of government has remained the same. The Government of Thailand is made up of three branches: the executive, the legislative, and the judiciary, the system of government is modelled after the Westminster system. All branches of the government are located within Bangkok, the capital city of Thailand.

As of December 2014 Thailand is ruled by a military junta, the National Council for Peace and Order, which has partially repealed the 2007 constitution, declared martial law and nationwide curfew, banned political gatherings, arrested and detained politicians and anti-coup activists, imposed internet censorship and taken control of the media.

The Monarchy

King Bhumibol Adulyadej has been on the throne since 1946.

The King of Thailand, King Bhumibol Adulyadej (or Rama IX), is the world’s longest reigning monarch, and has reigned since 1946. The Constitution stipulates that although the sovereignty of the state is vested in the people, the King will exercise such powers through the three branches of the Thai government. Under the constitution the King is given very little power, but remains a figurehead and symbol of the Thai nation. As the Head of State however he is given some powers and has a role to play in the machinations of government. According to the Constitution, the King is the Head of the Armed forces, required to be Buddhist as well as the defender of all faiths in the country. The King also retained some traditional powers such as the power to appoint his heirs, power to grant pardons and the royal assent. The King is aided in his duties by the Privy Council of Thailand.

The King is head of the House of Chakri, the ruling house of Thailand founded by King Buddha Yodfa Chulaloke (or Rama I) in 1782. The Monarchy and the Royal family commands huge respect in Thailand. The present monarch has a great deal of popular respect and moral authority, which has been used at times to resolve political crises. The monarch’s official home is the Grand Palace, however the present King lives primarily in the Chitralada Palace in Bangkok or the Klai Kangwon Villa, in Hua Hin. The Monarch's household is managed by the Bureau of the Royal Household and his finances by the Crown Property Bureau.

The heir to the throne is the Crown Prince of Thailand: Prince Maha Vajiralongkorn. The succession of the Throne is governed by the 1924 Palace Law of Succession, promulgated by King Vajiravudh. The Palace Law follows the male Agnatic Primogeniture, where males are only allowed to succeed and inheritance is passed only from father to son and through male line only.

Prime minister

Since 1932 the Head of Government of Thailand has been the "Prime Minister of Thailand": usually the leader of the largest party or the largest coalition party in the lower house of Parliament. The Prime Minister is, in accordance with the constitution, selected; first by an election in the lower house then officially appointed by the King.

The Prime Minister, as head of the executive branch, is also the leader of the Cabinet of Thailand. The Prime Minister therefore retains the prerogative to appoint or remove any Minister he or she so chooses. As the most visible member of the government the Prime Minister represent the country abroad and is as well the main spokesperson for the government at home. The Prime Minister’s official residence is Baan Phitsanulok a mansion located in the Dusit district of Bangkok.

The most recent Prime Minister was: Yingluck Shinawatra of the Pheu Thai Party, the first female prime minister of Thailand. She was removed from office by the Constitutional Court of Thailand on 7 May 2014, on charges of abuse of power. She was replaced by an interim prime minister, Niwatthamrong Boonsongpaisan, who is expected to hold the position until general elections occur in July. However there has been a military coup on May 22, 2014.


The Cabinet of Thailand or the Council of Ministers of Thailand is a council composed of 35: Ministers of State and Deputy Ministers, who run the cabinet ministries of the Kingdom. There are currently 20 cabinet ministries, which comprises the main portion of state employees. The Cabinet is also responsible for the formulation and execution of policies of the government. Members of the Cabinet do not necessarily need to be a member of the lower house, as in other countries but most often are. The Office of the Prime Minister and the Cabinet offices are located in a building complex called the Government House of Thailand.

The present Cabinet is not yet been appointed as the military junta which is led by Army General Prayuth Chan-ocha has seized the power from interim Prime Minister of Thailand Niwatthamrong Boonsongpaisan. He had replaced the Cabinet with the core members of the National Council for Peace and Order of Thailand to put in charge on country's affair.


Parliament House of Thailand the meeting place for both the House and the Senate since 1974.

National Assembly

The legislative branch (also called the Parliament of Thailand) of the Thai government was first established in the ‘Temporary’ Constitution of 1932. The assembly first met on 28 June 1932 in the Ananda Samakhom Throne Hall. The National Assembly of Thailand is a bi-cameral legislature and comprises two houses: the Senate and the House of Representatives. The legislative branch took its current form in 2007. The National Assembly has 630 members. Both houses of the National Assembly meet at the Parliament House of Thailand.

The Senate

The upper house of the legislative branch was first established in 1946. However for most of its history the Senate has been the stronghold of the military and the elite. The current Senate has 150 members. 76 members are elected, one per province from the 75 provinces of Thailand (Bueng Kan does not have an elected senator yet) and 1 from the Bangkok Metropolitan Area. The other 74 are selected by the Senate Selection Commission, made up of both elected and appointed officials.

The chamber is strictly a non-partisan chamber, and members may not be a member of a partisan organization, House of Representatives, judiciary and the Cabinet for five years. The Senate has little power legislative -wise, but retain considerable powers of scrutiny and appointment. As the Senate is vested with the power to ‘advise’ on the appointment of several members of the Judiciary and independent government agencies. The Senate sits for a set six years non renewable term, the Senate cannot be dissolved. The Senate is presided by a President of the Senate, who is also the Vice President of the National Assembly. He is assisted by two Vice Presidents of the Senate. The last election to the Senate was in 2008.

The Senate and the House of Representatives were abolished after the 22 May 2014 Coup by the " National Council for Peace and Order" (NCPO). Currently, according to the interim Constitution of Thailand imposed by NCPO, there is no Senate.

The House of Representatives

The lower house of the legislative branch has been in existence in some form since 1932. The House of Representatives is the primary legislative house of the government of Thailand. The House comprises 500 members. 375 of the MPs are elected directly from single-seat constituencies around the country. The other 125 members are selected using ‘proportional representation’ through party-lists. There are 8 electoral areas from which the proportionally representative votes are taken and 375 constituencies. This system is called the ‘Mixed Member Majoritarian’ in which a voter has two votes one for the constituency MP and the other for a party in the voter’s electoral area.

The House is a partisan chamber with seven political parties. The House is the primary legislative chamber and the more powerful of the two houses. The House has the power to remove both the Prime Minister and Cabinet Ministers through a vote of no confidence. The House sits for a term of four years however a dissolution of the House can happen anytime before the expiration of the term. The House is led by the Speaker of the House of Representatives, who is also the President of the National Assembly. He is assisted by two Deputy Speakers.

The leader of the largest party or largest coalition party will most likely become Prime Minister, while the leader of the largest party with no members holding any ministerial positions will become the Leader of the Opposition. The Leader of the Opposition is a powerful position with considerable influence, he is assisted by a Shadow Cabinet. The last general election for the House was in 2007.

After the 2007 election the People’s Power party won the most seats with the Democrats and Chart Thai party trailing behind. However after the 2008 political crisis and the ruling of the Constitutional court on 2 December 2008, in which the PPP plus the Chart Thai and Neutral Democratic Parties (coalition partners), the Prime Minister and several party executives were banned from politics for five years, the composition of the House changed. The successor of the PPP still retained the most seats, however the remainder of the coalition partners defected and joined a Democrat led government which was inaugurated on 17 December. Leaving the For Thais Party (successor of the PPP) and the Pracharaj Party in the opposition.

The House of Representatives and the Senate were abolished after the 22 May 2014 Coup by the " National Council for Peace and Order" (NCPO). Currently, according to the interim Constitution of Thailand imposed by NCPO, there is no House of Representatives. The legislative power is vested in the National Legislative Council, appointed by the NCPO.

The judiciary of Thailand is composed of three distinct systems: the Court of Justice system, the Administrative Court system and the Constitutional Court.

Courts of Justice

The Courts of Justice of Thailand is the largest of the court system and makes up the majority of courts in the Kingdom. The Courts as mandated in the Constitution is made up of three tiers: the Court of First Instance, the Court of Appeals and the Supreme Court of Justice of Thailand.

There are no stenographic records kept by the trial court and the record is composed of what the judges decide.

Research judges assist the sitting judges. Judges must take an examination and two different examinations are given: one exam is for judges trained in Thailand and a different examination is given for judges who graduate from foreign law schools. All Judges are formally appointed by the King.

The Asian Human Rights Commission called the Thai legal system a "mess" and called for a drastic overhaul of Thailand's criminal procedures. It cited the rampant use of forced confessions, and the fact that even a senior justice ministry official admitted that 30% of cases went to court with no evidence. It also criticized the judiciary for failing to ensure that trials are conducted speedily, citing the case of four Thai men accused of plotting to kill Supreme Court President Praman Chansue (Thai: ประมาณ ชันซื่อ). The accused were present in court 461 times before 91 different judges since proceedings began in 1993 and ended in 2008. While these proceedings continued, Mr. Praman peacefully died of intrapulmonary infection in 2007.[1]

Administrative Courts

The Administrative Court system is made up of two tiers: The Administrative Courts of First Instance and the Supreme Administrative Court. The court system was first created in 1997, the court’s main jurisdiction is to settle litigation between the State or an organ of state (government ministries, departments and independent agencies) and private citizens.

Constitutional Court

First set up in 1997, the Constitutional Court of Thailand was created solely as a high court to settle matters pertaining to the constitution. The court has since accumulated huge amounts of power and influence; gaining many controversies on the way. This has become especially clear during the 2006 and 2008 political crises, settling political deadlocks and social unrest.

The Legal system

Thailand's legal system blends principles of traditional Thai and Western laws; the western sourced laws are often misused and corrupted. The traditional 'Thai' laws are the product of Hindu-Brahmin laws used by the Khmer Empire. There is no discovery in the Thai legal system. Slander and libel are not civil torts in Thailand but criminal offenses.

Thailand’s legal system has been often criticized by other countries for having penalties of life in prison or even death for crimes such as drug possession or smuggling, while having lenient penalties for crimes such as terrorism and marital abuse resulting in spousal death.

The criminally accused are entitled to have a court-appointed certified translator present in court if they cannot afford one. Appeals must be filed with the trial court within thirty (30) days of the judge reading, signing and issuing the verdict. There are no juries in trials. Only Thai citizens can be admitted to the Bar and can practice before the courts. Attorneys must carry their current, yellow, bar card when in court and may be required to produce it on challenge.

In Thailand's southern border provinces, where Muslims constitute the majority of the population, Provincial Islamic Committees have limited jurisdiction over probate, family, marriage, and divorce cases.

Local government

Thailand is divided into seventy-six provinces (changwat, singular and plural). The Ministry of the Interior appoints governors for all provinces. The metropolis of greater Bangkok is a special administrative area at same level as a province, but the governor is popularly elected. Thailand's provinces are listed below. Note that each provincial capital takes the same name as the province.
