Thailand has enacted comprehensive sexual harassment legislation that significantly expands criminal penalties and creates new compliance obligations for online platform operators. The Act Amending the Penal Code (No. 30) B.E. 2568 (2025), enacted on December 29, 2025, and taking effect the following day, introduces a comprehensive definition of sexual harassment, establishes new criminal offenses with graduated penalties, and imposes content removal obligations on social media platforms and computer system service providers. The amendment, which establishes a comprehensive framework for addressing sexual harassment in both physical and digital environments, significantly expands legal exposure for online service operators. It also grants courts authority to order takedowns of violating data accessible to the public. Definition of Sexual Harassment The law introduces “sexual harassment” as a distinct statutory concept covering physical conduct, verbal conduct, sounds, gestures, expressions, postures, communications, surveillance, stalking, and acts committed through computer systems or electronic devices. Conduct qualifies as sexual harassment when it is sexual in nature and likely to cause the victim distress, annoyance, embarrassment, humiliation, fear, or a sense of sexual insecurity. Criminal Offenses and Penalties The amended Penal Code establishes graduated penalties based on the severity and context of the harassment—including enhanced penalties for public or online conduct. For instance: Basic sexual harassment is punishable by imprisonment for up to one year, a fine of up to THB 20,000, or both. Continuous or repeated harassment that prevents normal life escalates penalties to imprisonment for up to two years, a fine of up to THB 40,000, or both. Critically for online operators, harassment committed in public places, in the presence of the public, or through computer systems accessible to the general public triggers imprisonment for up to three years, a fine of up to THB 60,000, or both. Acts of harassment committed by supervisors, employers, or others
