The Royal Gazette on Sunday (August 23, 2026) published the Act on Promoting a Peaceful Society B.E. 2569 (2026), creating an amnesty for qualifying offences arising from political demonstrations or political expression over a period of more than 20 years.
The law was published in Volume 143, Part 50 Kor, beginning on page 1, and will take effect on Monday, the day after its publication.
Promulgated with the advice and consent of Parliament, the Act is intended to address prolonged political conflict by granting amnesty to people whose participation in political gatherings or political expression arose from political conflict or political motivation.
It covers eligible acts committed from January 1, 2005, to July 16, 2025.
The law applies to qualifying offences listed in an annex to the Act, together with related offences, where the conduct arose from participation in political demonstrations or political expression motivated by political conflict.
Qualifying acts are treated as no longer constituting offences. Those covered are relieved of criminal and regulatory-penalty liability, provided this does not conflict with Thailand’s obligations under international law.
Related civil proceedings brought by state agencies or state enterprises are also terminated. However, the law does not extinguish liabilities owed directly to private individuals or specific private groups.
The legislation is intended to ease the effects of political prosecutions accumulated over more than two decades and support national reconciliation.
The Act expressly excludes several categories of conduct from the amnesty:
These exclusions are set out in Section 3 of the final text.
Section 112 cases are excluded in all circumstances. A provision allowing rehabilitative measures for people who were under 18 when an offence was committed also does not apply to Section 112.
The law establishes a nine-member Committee on Promoting a Peaceful Society to determine who qualifies for amnesty and exemption from liability.
The committee will comprise:
The four appointed experts must not have an interest in any matter covered by the Act.
The committee must hold its first meeting within 30 days of the law taking effect.
It will have the authority to decide eligibility for amnesty, receive applications from interested parties, request documents or testimony, appoint subcommittees and issue recommendations concerning the promotion of a peaceful society.
Its rulings will be final and binding on state agencies involved in the justice system.
The committee must complete its work within 180 days of its first meeting. The deadline may be extended no more than twice, with each extension limited to 90 days.
