The Peaceful Society Promotion Act has been published in the Royal Gazette and will take effect on Monday, granting amnesty for a wide range of political offences committed over the past two decades, but excluding lese majeste cases.

The law covers people who took part in political demonstrations or political expression stemming from political conflict or political motivations between Jan 1, 2005 and July 16, 2025.

However, the legislation does not extend amnesty to offences under Section 112 of the Criminal Code, the lese majeste law. Corruption offences, crimes resulting in death or serious injury or offences involving personal liability to private individuals or non-state entities are also excluded.

Often referred to as the political amnesty law, the legislation aims to resolve legal disputes arising from years of political unrest, from the yellow-shirt and red-shirt movements to more recent political protests.

The law's exclusion of Section 112 offences has been one of its most controversial provisions, as many defendants charged under the law are young activists involved in youth-led protests after 2020. Critics have argued that the omission limits the legislation's ability to fully heal political divisions.

Under the law, eligible offences include a broad range of crimes commonly associated with political demonstrations, such as sedition, violations of emergency regulations, public assembly offences and certain computer crime offences.

The legislation allows investigations and prosecutions involving eligible offences to be terminated, pending court cases to be dismissed, prison sentences to end, and criminal records relating to those offences to be cleared.

A nine-member Peaceful Society Promotion Committee, chaired by the prime minister, will determine who qualifies for amnesty. Its decisions will be final and binding on state agencies involved in the justice process.

The law was approved by parliament and received royal endorsement on Tuesday before being published in the Royal Gazette on Sunday. It takes effect a day after publication.
