Origin and early developments In the feudal era, monarchs, royal officials, royal symbols, and wrongdoings in the palace were protected from many kinds of "violation". removing the right to express opinions which might be insulting to the monarchy if said within the spirit of the constitution. Court decisions shortly after the change still took context into consideration. In December 1957, a case against a politician was dismissed because a political campaign was underway. In Order No.41, the penalty for
lèse-majesté was increased from a maximum of seven years imprisonment to three to fifteen years per count. Other than the
Empire of Japan during World WarII, Thailand is the only
constitutional monarchy that strengthened
lèse-majesté in the 20th century. In March 2007, Oliver Jufer, a Swiss man, was sentenced to 10 years in prison for spray-painting graffiti over five posters of King Bhumibol while drunk in
Chiang Mai, although he received a royal
pardon the following month.
Political weaponisation Between 1990 and 2005, there was an average of five new
lèse-majesté cases per year. Since then, however, there have been at least 400 cases—an estimated 1,500 per cent increase. In 2005, cases registered in the Attorney General's office rose sharply from 12 new cases in 2000–2004 to 17. After the coup, dozens of radio stations were shut down because of alleged
lèse-majesté. Academics have been investigated, imprisoned and forced into exile over accusations of
lèse-majesté. Prominent historian
Somsak Jeamteerasakul was arrested for proposing an eight-point plan to reform of the monarchy.
Giles Ji Ungpakorn went into exile in 2007 after his book,
A Coup for the Rich, questioned Bhumibol's role in the 2006 coup. In March 2011,
Worachet Pakeerat, a law lecturer, banded together with same-minded lecturers and formed the
Nitirat Group, aiming to amend the
lèse-majesté law. He proposed reducing the maximum jail term to three years, a circumstance for pardoning, and that only the Office of His Majesty's Principal Private Secretary could file a complaint. His actions angered many people. In February 2012, he was assaulted in broad daylight in Bangkok. During the government of
Yingluck Shinawatra, the number of arrests and convictions for
lèse-majesté offences declined significantly. There were 478 cases in 2010. In May 2014, the
National Council for Peace and Order (NCPO), the
military junta, granted authority to a military tribunal to prosecute
lèse-majesté in Thailand. Military courts routinely imposed harsher sentences than civilian courts would. In August 2015, the Bangkok Military Court sentenced Pongsak Sriboonpeng to 60 years in prison for his six Facebook postings (later reduced to 30 years, when he pleaded guilty). This was Thailand's longest recorded sentence for
lèse-majesté. The courts were dubbed "
kangaroo courts." iLaw, a Thai non-profit organisation, reported that the junta hold persons in custody for seven days without charges.
Secret trials were held. Officials seized personal communication devices to search for incriminating evidence. In December 2014, the parents of
Srirasmi Suwadee, formerly a Thai princess, were sentenced for "insulting the royal family and lodging a malicious claim". In 2015,
Prachatai published an infographic showing that bathroom
graffiti, a hand gesture, a hearsay report of a taxi conversation, and not standing during the playing of the
royal anthem, among other things, could be punished as acts of
lèse-majesté. A nurse wearing black on
Bhumibol Adulyadej's birthday was charged with
lèse-majesté. The last formal attempt to amend the law occurred in May 2012 when more than 10,000 people signed a petition to parliament, but Speaker of the House of Representatives, Somsak Kiatsuranont, dismissed it citing that amendment of the law concerning the monarchy was not a
constitutional right.
Enforcement under King Vajiralongkorn Following the ascension of
King Vajiralongkorn to the throne in 2016, the enforcement of Thailand’s
lèse-majesté law intensified under the military junta government, the
National Council for Peace and Order (NCPO). In December 2016, activist
Jatupat Boonpattararaksa, a member of the rights group Dao Din, was arrested and charged with
lèse-majesté after sharing a
BBC Thai biography of the new monarch on
Facebook. Despite over 2,600 others having shared the same article, Jatupat was the only individual prosecuted. Neither the publisher, BBC Thai, nor other sharers faced legal action. In May 2017, the NCPO further expanded the law's scope, declaring that even viewing royal-related content deemed offensive could constitute
lèse-majesté and be subject to prosecution. As of November 2018, at least 127 people had been charged with
lèse-majesté since the 2014 coup. In 2017, Thai authorities charged a 14-year-old boy with
lèse-majesté for allegedly burning a royal arch in
Khon Kaen, marking the first known prosecution of a minor under the law. A lawyer in the case argued that the court lacked impartiality, as proceedings were carried out in the name of the King, who was a party with a vested interest. A directive from the Attorney General's Office, dated 21 February 2018, stipulated that only the Attorney General himself could authorize
lèse-majesté prosecutions. In June 2018, new regulations permitted prosecutors to dismiss cases not deemed to serve the public interest. Subsequently, several cases were dismissed even when defendants had pleaded guilty, and bail was granted in some
lèse-majesté trials—an unprecedented development. Nevertheless, authorities increasingly substituted the use of Section 112 with other statutes such as the Computer Crime Act or
sedition law. Following the forced disappearance of exiled activist
Wanchalearm Satsaksit in June 2020—himself accused of
lèse-majesté—the
hashtag #ยกเลิก112 (“Repeal 112”) trended nationwide on
Twitter with over 500,000 retweets, as many believed the charges against him were a factor in his abduction. By August 2020, during the height of the
anti-government demonstrations, calls to reform the monarchy and abolish Article 112 became central among protest demands. ,
Arnon Nampa, and
Somyot Prueksakasemsuk received bail on 2 November 2020. In January 2021, Anchan Preelerd received the harshest
lèse-majesté sentence in Thai history—87 years in prison—for uploading and sharing online talk show videos. After pleading guilty, her sentence was reduced by half to 43.5 years. The
United Nations Human Rights Committee later declared that "imprisonment is never an appropriate penalty" for such cases. In the same year, opposition leader
Thanathorn Juangroongruangkit was charged with
lèse-majesté after he criticized the government's
COVID-19 vaccine procurement strategy for relying heavily on
Siam Bioscience, a company owned by the King, despite its lack of prior vaccine experience. The
Royal Thai Police charged him following his 18 January 2021 Facebook Live broadcast. The
Technology Crime Suppression Division ordered the removal of the video. In August 2021, Thanathorn faced two additional
lèse-majesté charges for the same incident. By late 2021, Prime Minister Prayut had revived active enforcement of the
lèse-majesté law in response to the ongoing protests. Since November 2020, at least 173 people have been charged under the law. On 14 May 2024, activist
Netiporn Sanesangkhom, died in custody following a prolonged
hunger strike protesting political imprisonment and judicial injustice. After the
2023 Thai general election, the
Move Forward Party, led by
Pita Limjaroenrat—which won the most parliamentary seats—was barred from forming a
coalition government due to its platform advocating the amendment of Section 112. In January 2024, the
Constitutional Court ordered the party to cease any effort to reform the law. Subsequently, in August 2024, the Court ordered the dissolution of the Move Forward Party. == Statistics ==
