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 cases from the same facts without reasonable cause; and
Penalizing a defendant who merely exercised
