The Appeal Court has found Mongkhon Thirakot, a Chiang Rai-based activist and online clothes vendor, guilty of royal defamation and violation of the Computer Crimes Act and sentenced him to 4 years and 6 months in prison for two Facebook posts made in July 2022.

The ruling upholds a 30 October 2023 verdict by the Chiang Rai Provincial Court which found that Mongkhon was guilty of royal defamation and violation of the Computer Crimes Act. He was initially sentenced to 4 years in prison and given an additional 6 months in prison on a trespassing charge.

Thai Lawyers for Human Rights (TLHR) reports that the Appeal Court ruled to uphold the verdict on the grounds that Mongkhon admitted that he made the posts and that they referred to King Vajiralongkorn. The Court found that the two posts, which appeared to refer to ordinary people, were rude and inappropriate. Written with the intent of insulting the King, they were deemed to constitute an offence under the royal defamation law. The court noted that the defendant’s discontent with the current political situation was not a valid excuse for the offence.

Mongkhon was charged with royal defamation and violation of the Computer Crimes Act for two Facebook posts made on 28 and 30 July 2022. One contains a picture of King Vajiralongkorn and a message about wearing black while in mourning. The other contains an edited picture of Mongkhon holding a picture frame.

He was arrested at his family home in Chiang Rai on 11 August 2022 by a unit of 21 police officers. He was later released on bail. The public prosecutor indicted him on the grounds that the posts insulted the King and damaged his reputation.

Mongkhon was previously sentenced to 50 years in prison on 25 counts of royal defamation for Facebook posts made between 2 – 11 March 2021. He is now facing a cumulative prison sentence of 54 years and 6 months, currently the longest prison sentence ever given for a royal defamation. Since January 2024, he has been detained pending appeal at the Chiang Rai Central Prison after the Supreme Court denied him bail on the grounds that his lengthy sentence makes him a flight risk.
