Section 112 of Thailand's Criminal Code, enacted in 1956 (last edited 1976), criminalizes acts of defamation, insult, or threats against the monarchy, including the King, Queen, Heir-Apparent, or Regent. Violations carry a prison sentence ranging from 3 to 15 years. This provision falls under "Crimes Against the Security of the Kingdom" and is categorized within offenses specifically related to the monarchy.

The law permits any individual to file a complaint, leading to police investigations. Authorities often proceed with such cases to avoid accusations of neglecting their duties.

Currently, Section 112 remains controversial, with divided opinions:

1. Proponents support maintaining the law as it stands, citing the need for strong protection of the monarchy.

2. Critics advocate for amendments, suggesting:

  • Limiting the right to file complaints.
  • Distinguishing between good-faith criticism, defamation, insults, and threats by creating subcategories.
  • Reducing the severity of penalties.
