Lawyers for Lawyers (L4L), the International Bar Association Human Rights Institute (IBAHRI), The Law Society of England and Wales (LSEW) and the International Observatory for Lawyers at Risk (OIAD) condemn the latest conviction of Thai human rights lawyer Arnon Nampa under Section 112 (lèse-majesté) of the Thai Criminal Code. On 30 October 2026, Mr. Nampa was sentenced to four years in prison, subsequently reduced to two years and eight months, for speeches delivered during a peaceful assembly. This marks his twelfth conviction under the controversial lèse-majesté law, bringing his cumulative prison sentence to 34 years, five months and 20 days. Mr. Nampa has been detained since 26 September 2023.
Background: Arnon Nampa and the prosecutions against him
Arnon Nampa is a prominent Thai human rights lawyer and a founding member of Thai Lawyers for Human Rights (TLHR) who has dedicated himself to defending individuals charged under the lèse-majesté law, despite facing sustained harassment by state authorities as a result of his work. In addition to his legal practice, Mr. Nampa has participated in public discussions concerning constitutional reform, democracy, and the role of the monarchy. He received the Front Line Defenders Award for Human Rights Defenders at Risk in 2025, and the Gwangju Prize for Human Rights in 2021 in recognition of his efforts to challenge the violent crackdown on protesters during Thailand’s political unrest. His public advocacy during Thailand’s 2020–2021 pro-democracy movement has resulted in numerous criminal proceedings, primarily under the controversial lèse-majesté law, which makes criticism of the monarchy punishable by up to 15 years in prison, equivalent to the penalty for manslaughter.
Between 2020 and 2022, authorities arrested and detained Mr. Nampa several times in different cases. He has faced 14 separate lèse-majesté cases and has been convicted in 12 of them. In addition to the criminal proceedings, Mr. Nampa has also been subjected to disbarment proceedings before the Lawyer Council of Thailand under the Royal Patronage, which seek the revocation of his license to practice law in connection with a speech delivered during the protest on 3 August 2020. The proceedings, arising from Mr. Nampa’s exercise of freedom of expression and peaceful assembly, have remained pending for more than five years and are currently under consideration by the Lawyer Council’s Professional Etiquette Committee.
Judgment by the Court of First Instance on 30 October 2026
The present case concerns speeches delivered at a public assembly on 25 November 2020. Mr. Nampa’s speech addressed the King’s alleged interference in the constitutional amendment process, the allocation of public funds to the monarchy, and amendments to the Crown Property Act.
On 30 October 2026, the Criminal Court found Mr. Nampa and four colleagues guilty under Section 112 and sentenced them to four years’ imprisonment. It reduced the sentence by one-third in light of their testimony, resulting in a final sentence of two years and eight months. The Court found that Mr. Nampa’s speech defamed the King and undermined the inviolable status the Constitution grants him.
Judicial harassment and misuse of Section 112
Mr. Nampa’s prosecution forms part of a broader pattern of judicial harassment and criminal proceedings against lawyers, human rights defenders, journalists and pro-democracy activists under Section 112 of the Thai Criminal Code. The broad interpretation and application of this provision have enabled the criminalisation of peaceful expression concerning the monarchy, severely restricting freedom of expression and public debate while exposing individuals to lengthy prison sentences for exercising their fundamental rights. UN human rights experts have repeatedly called on Thailand to repeal its lèse-majesté laws, raising serious concerns about their incompatibility with international human rights standards.
The repeated prosecutions of Mr. Nampa, the accumulation of lengthy prison sentences and the persistent denial of bail raise serious concerns that criminal proceedings are being used to punish and deter legitimate human rights advocacy and peaceful political expression. The prosecution and imprisonment of a human rights lawyer for participating in public debate not only violate his fundamental rights but also undermine the independence of the legal profession. Such measures risk creating a chilling effect on other lawyers, discouraging them from engaging in human rights advocacy, representing individuals in politically sensitive cases or speaking out on matters of public interest.
These concerns are further reinforced by the findings of the United Nations Working Group on Arbitrary Detention (WGAD). In its Opinion No. 28/2024 concerning Arnon Nampa, adopted during its 100th session in August 2024, the Working Group concluded that his deprivation of liberty was arbitrary and in violation of Thailand’s obligations under international human rights law. Notably, the Working Group found that Mr. Nampa had been “deprived of his liberty on discriminatory grounds on the basis of his political or other opinion regarding the lèse-majesté law”. It therefore called on the Thai authorities to release him immediately and grant him an enforceable right to compensation and other reparations, in accordance with international law. Despite these findings and recommendations, Mr. Nampa remains imprisoned and continues to face further convictions under Section 112.
Exclusion of Section 112 in Thailand’s recently enacted amnesty law
In August 2026, Thailand enacted a law that provides amnesty to individuals charged, prosecuted, and convicted in connection with political expression and/or public assemblies between 2005 and 2025. However, the law explicitly excludes offenses under Section 112. Since November 2020, close to 300 people have been charged and/or prosecuted under Section 112, including 20 children. Among them are Mr. Nampa and at least 32 other political prisoners who are currently detained in prison.
Thailand’s international human rights obligations
Thailand is a State Party to the International Covenant on Civil and Political Rights (ICCPR) and has obligations to guarantee the rights to liberty, a fair trial, freedom of expression, peaceful assembly and participation in public affairs under Articles 9, 14, 19, 21 and 25. Furthermore, the UN Basic Principles on the Role of Lawyers recognise the essential role lawyers play in upholding the rule of law and protecting human rights. Principle 23 provides that lawyers, like other citizens, are entitled to freedom of expression, belief, association and assembly. In particular, they have the right to take part in public discussion of matters concerning the law, the administration of justice, and the promotion and protection of human rights, without suffering professional restrictions or other reprisals because of their lawful actions or membership in a lawful organisation. The continued prosecution and detention of Mr. Nampa are inconsistent with these internationally recognised standards.
Thailand also serves on the UN Human Rights Council for the 2025-2027 term. Under UN General Assembly resolution 60/251, members of the Council must uphold the highest standards in the promotion and protection of human rights. While campaigning for its seat, Thailand pledged to “take steps towards developing and revising legislation, policies and regulations to be in line with international human rights treaties to which Thailand is party and ensure effectiveness of the national implementation thereof.” Thailand is also scheduled to undergo its fourth Universal Periodic Review on 9 November 2026. In the previous cycle, Member States made at least 12 recommendations to Thailand concerning Section 112. The undersigned organisations consider that the conviction of Mr Nampa under Section 112, nine days before the review, is difficult to reconcile with these commitments.

The OIAD denounces in the strongest possible terms the arrest of lawyer Arnon Nampa after he attended a rally calling for reform of monarchy.
Mr Arnon Nampa is an eminent human right lawyer and member of the human rights award winner Thai Lawyers for Human Rights -TLHR. This award was presented to the organization by the French Embassy in Bangkok on the occasion of the International Human Rights Day on December 10th, 2014. Already arrested earlier this month before being released on bail, Arnon Nampa has been arrested again for a third time on August 25th, and prosecuted for sedition over his role in a political rally where calls were made for reforms to the country’s monarchy.
Mr. Arnon Nampa calls for the withdrawal of Thailand’s lese majeste law, which punishes criticism of the monarchy with up to 15 years of prison.
This arrest comes in a context where police has arrested student leaders, rappers and activists for participating in demonstrations against the military junta.
Such harassment and prosecution committed to the detriment of a lawyer is a breach of international standards.
The OIAD urges the Thai authorities to respect the Basic Principles on the Role of Lawyers, adopted by the United Nations in Havana in 1990, which provide that:
“ Lawyers like other citizens are entitled to freedom of expression, belief, association and assembly. In particular, they shall have the right to take part in public discussion of matters concerning the law, the administration of justice and the promotion and protection of human rights and to join or form local, national or international organizations and attend their meetings, without suffering professional restrictions by reason of their lawful action or their membership in a lawful organization.“ (Principle No. 23).
The OIAD is concerned about the charges against him and the risk of serious and disproportionate punishment and lawyers and calls for the immediate release of Mr Arnon Nampa and the abandonment of prosecutions.
The OIAD will follow with attention the follow-up given to this serious violation of the rights of lawyer.
