Thailand's constitutional court has ruled that the Move Forward party's campaign promise to amend the strict royal insult law during the 2023 election amounted to an attempt to overthrow the monarchy. The case was initiated by a conservative activist lawyer, who argued that the party's pledge to amend the lèse-majesté law violated Section 49 of the constitution. The nine judges unanimously ruled against Move Forward, stating that its efforts to change the law undermined and weakened the monarchy, posing a significant danger to the state's security. Move Forward was ordered to cease any activities violating Section 49. The party is not being disbanded, but the lawyer has said he might make a new petition asking the election commission to do so. Move Forward's leader warned that the ruling could further make the royal institution increasingly ‘a factor behind conflicts in Thai politics’.
