The Senate has approved the Peaceful Society Promotion Bill, paving the way for an amnesty for a wide range of political offences committed over the past two decades while excluding cases under the lese majeste law.

The legislation, often referred to as the "political amnesty bill", aims to resolve legal disputes stemming from years of political unrest, from the yellow-shirt and red-shirt movements to more recent youth-led protests.

Yet the exclusion of offences under Section 112 of the Criminal Code, known as the lese majeste law, has fuelled debate over whether it can fully address the country's political divisions.

The bill was approved by the Senate on June 30 by 103 votes to 3, with 22 abstentions.

Senators retained the original principle that offences under Section 112 will not qualify for an amnesty. The legislation also excludes corruption offences and crimes resulting in death or serious harm.

If enacted, the law would erase criminal liability for political actions committed between Jan 1, 2005 and July 16, 2025, provided they fall within offences listed in the bill. It would apply to people who participated in political demonstrations or political expression motivated by political conflict.

Investigations and prosecutions involving eligible suspects would be halted. Pending court cases would be dismissed, convictions would be deemed never to have occurred, prison sentences would end immediately, and criminal records relating to eligible offences would be removed.

As senators made changes to the version previously approved by the House of Representatives, it will now be returned to the Lower House for further consideration.

If approved, it will be submitted to the prime minister for royal endorsement before becoming law. If the House disagrees with the Senate's amendments, a joint parliamentary committee will seek a compromise.

Amnesty for past movements

The bill arrives at a time when the political landscape has changed considerably from the period dominated by street protests, and the intense rivalry between political camps has gradually diminished.

As a result, some observers believe the bill's role in easing political tensions may be more limited than it would have been several years ago.

However, the legislation could still benefit senior political figures, protest leaders and state officials whose actions during earlier periods remain subject to legal proceedings.

It could also resolve cases involving security personnel who carried out official duties during political crackdowns, preventing the reopening of past prosecutions.

But because the bill excludes Section 112 offences, many participants in more recent youth protests would not qualify for amnesty if their cases involve the lese majeste law.

Many lese majeste defendants are young activists involved in protests after 2020. The exclusion has raised doubts about whether the legislation can genuinely resolve political divisions across generations.

Some observers also say lengthy legal proceedings have effectively limited political mobilisation among younger activists by keeping many cases unresolved.

Stithorn Thananithichot, a political scientist at Chulalongkorn University, said the legislation combines two issues that are difficult to reconcile.

He said excluding Section 112 from the amnesty is broadly consistent with discussions during the earlier yellow-shirt and red-shirt conflicts, when relatively few such cases were involved.

The situation has changed after the emergence of youth-led protests, with many young activists facing prosecution under Section 112. Excluding those cases means the amnesty cannot fully resolve political divisions, he said.

If Section 112 cases remain outside the amnesty process, the justice system should instead move forward without delay, he said, arguing prolonged legal uncertainty should not continue indefinitely.

"I understand there are concerns that including Section 112 cases in the amnesty could send the wrong message to the youth groups who were engaged in violent activities. An immediate pardon could be seen as encouraging repeat offences.

"If those cases are not covered by the amnesty, the ordinary justice process should proceed instead. That is the trade-off that needs to be made if this issue is to be resolved rather than left dragging on.

"At present, the cases appear to be kept pending to discourage young people from returning to political activism. Even so, I believe the youth movement no longer has the momentum it once did, and many of those involved have already learned from the experience."

Mr Stithorn also said he expected the House of Representatives to reaffirm the bill's current approach when it returns for consideration.

Limits of reconciliation

Olarn Thinbangtieo, a political scientist at the Faculty of Political Science and Law at Burapha University, said the bill reflects a degree of reconciliation among leaders from earlier conflicts.

He questioned whether the legislation adequately addresses today's political realities.

Mr Olarn said the country's most significant unresolved political dispute now involve young people prosecuted under Section 112 rather than the conflicts associated with the yellow-shirt and red-shirt era.

He said the legislation largely resolves disputes among political leaders while offering little certainty for younger defendants whose cases remain outside its scope.

Any future attempt to extend amnesty to Section 112 cases would be unlikely unless the People's Party (PP) is able to form a government. Until then, he expects prosecutions under the law to continue.

He also urged parties to pay greater attention to the situation facing younger defendants.

"While political leaders are being granted an amnesty despite the divisions that affected the country for more than a decade, the actions of young people have had far less impact on the overall political structure. They deserve an opportunity to move on.

"In many cases, their age, maturity and intentions did not cause lasting damage to the country. They have also learned important lessons from their experiences and have come to understand the realities of politics, including that the people and parties they placed their hopes in eventually left them behind," he said.

Inside the bill

The Peaceful Society Promotion Bill would be the country's 24th political amnesty law since the first amnesty decree following the 1932 change of government.

The House of Representatives approved the legislation in October 2025 before forwarding it to the Senate. Consideration was suspended after parliament was dissolved in December that year before the government sought to revive the bill in the new parliamentary session.

The Senate committee completed its review without altering the bill's core principles before the chamber approved it.

The legislation excludes three categories of offences from amnesty: corruption, offences under Section 112, and crimes resulting in death or serious injury.

Eligible offences cover 42 criminal provisions contained in 29 laws, including sedition, emergency decree violations, public assembly offences, computer crime offences and several other offences commonly associated with political demonstrations.

Under the bill, a nine-member Peaceful Society Promotion Committee, chaired by the prime minister, would determine eligibility for amnesty. Its decisions would be final and binding on all state agencies involved in the justice system.

The committee would include the Justice Ministry, the National Human Rights Commission, legal and human rights experts nominated by both government and opposition parties, an academic representative, a civil society expert in conflict resolution and the permanent secretary to the Prime Minister's Office.

The committee would be required to carry out its responsibilities within 180 days of its first meeting. Under the Senate's version, committee members acting in good faith would be protected from liability while on duty.
