Thai Opposition Leader Faces Court Pressure Over Attempt to Reform Lèse-Majesté Law
Thailand’s Supreme Court has agreed to hear an ethics case against the leader of the main opposition party and dozens of MPs over a failed bid to amend the country’s strict monarchy defamation law.
Thailand’s Supreme Court has agreed to proceed with an ethics case against the leader of the country’s main opposition party and 43 other current and former lawmakers over their attempt to reform the kingdom’s strict lèse-majesté law, a move that could end their political careers if they are found guilty.
The case centres on a 2021 legislative proposal to amend Section 112 of Thailand’s Criminal Code, which criminalises criticism of the monarchy and carries penalties of up to 15 years in prison per offence.
The opposition figure at the centre of the case is Natthaphong Ruengpanyawut, leader of the progressive People’s Party, which emerged as the successor to the dissolved Move Forward Party.
That earlier party had pushed for reform of the lèse-majesté law as part of its broader democratic platform before being disbanded by the Constitutional Court in 2024, which ruled its reform agenda undermined the constitutional order.
The National Anti-Corruption Commission referred the lawmakers to the Supreme Court, alleging their actions in co-sponsoring the reform bill constituted a breach of political ethics.
On Friday, the court accepted the case for consideration but declined to suspend the 10 sitting MPs from their parliamentary duties while proceedings continue.
If ultimately convicted, the lawmakers could face lifetime bans from holding political office.
What remains unclear is how quickly the case will proceed and how broadly the court will interpret political ethics standards in relation to legislative activity.
The outcome is likely to be closely watched in Thailand’s volatile political landscape, where legal action against reformist parties has repeatedly reshaped the opposition.
The People’s Party, despite finishing second in the most recent general election, now faces renewed legal pressure tied directly to policies it previously championed.
The lèse-majesté law itself remains one of Thailand’s most sensitive political instruments, shielding the monarchy from criticism and frequently used in prosecutions against activists and dissidents.
Human rights groups have long argued that its broad application has had a chilling effect on free expression, while supporters of the law describe it as essential to protecting national stability and the monarchy’s constitutional role.
