The president of Thailand’s Supreme Court has issued new recommendations providing courts with criminal jurisdiction with a comprehensive framework for identifying and dismissing criminal cases brought in bad faith. Published in the Government Gazette on May 29, 2026, after being signed on May 25, the Recommendations of the President of the Supreme Court Concerning Bad-Faith Litigation in Criminal Cases B.E. 2569 were issued under Section 5 of the Act on the Organization of Courts of Justice. The recommendations took effect upon publication and represent a significant step in Thailand’s efforts to curb abusive criminal litigation, including strategic lawsuits against public participation (SLAPP). Background Section 161/1 of Thailand’s Criminal Procedure Code empowers courts to dismiss criminal cases filed dishonestly or with the intent to harass or take unfair advantage of a defendant. The new recommendations provide detailed guidance that courts previously lacked on identifying and handling such prosecutions. Definition of Bad-Faith Litigation Under recommendation 1, filing a criminal case in bad faith is defined broadly to encompass three categories: Harassment-type filings involving intimidation, threats, or creating unreasonable hardship for the defendant; Coercive filings designed to pressure the defendant into acting or refraining from acting for illegitimate benefit; and False or misleading filings that deliberately assert incorrect material facts or conceal such facts. Circumstances Indicating Bad Faith Recommendation 2 sets out specific circumstances that should raise a court’s suspicion that a filing may violate section 161/1. These include: Filing in a distant court far from the defendant’s domicile without benefiting the adjudication; Retaliation against the defendant’s advocacy for human rights, environmental protection, consumer rights, labor rights, or other public interests—effectively establishing an express anti-SLAPP framework; Retaliation against whistleblowers who disclosed corruption or unlawful conduct; Retaliation against individuals responsible for investigating the plaintiff’s wrongdoing or who concluded such an investigation; Filing multiple

On September 15, 2025, Thailand’s Senate approved a draft amendment to the Labor Protection Act (LPA), which is currently awaiting publication in the Government Gazette. The amendment, which will take effect 30 days after publication, extends labor protections to certain service contractors working for state entities, enhances maternity and spousal support leave, and updates employer reporting obligations. Expanded Protections for State-Contracted Service Providers The amendment adds a section to the LPA that extends core labor protections to individuals engaged by government bodies under service contracts. This provision covers workers hired by central, regional, and local government agencies; state enterprises governed by the State Enterprise Labor Relations Act; public organizations; and other state agencies when these entities retain individuals under service procurement contracts (or similar arrangements) and exercise supervision, direction, and control over their work. In such cases, the hiring agencies must provide terms no less favorable than those required under the LPA for remuneration, weekly holidays, traditional holidays, annual leave, sick leave, maternity leave, working days and hours, and rest periods. Ministerial regulations will establish specific criteria for implementation. Disputes regarding rights and duties under this provision will fall under Labor Court jurisdiction. This change aligns the treatment of controlled service contractors with that of regular employees, addressing a longstanding coverage gap in the public sector. Enhanced Maternity Leave and New Caregiving Provisions The amendment includes a maternity leave entitlement of up to 120 days per pregnancy (an increase from the previous 98 days), unless otherwise prescribed by royal decree, and also introduces a new postnatal caregiving leave for mothers in complex medical situations who have used their childbirth leave, granting up to 15 additional days to care for children who are at risk of complications, have abnormalities, or have disabilities. This supplemental leave requires support from a medical
