A top court in Thailand ordered the country¡¯s main opposition Move Forward Party to cease all attempts to amend the country¡¯s stringent royal insult law, a centerpiece of its reformist agenda that helped it win last year¡¯s election.

The Constitutional Court on Wednesday ruled that the party¡¯s campaign to loosen Article 112, known as lese majeste law, violated the charter. The nine-member court said in a unanimous ruling that Move Forward¡¯s push for changes amounted to an attempt to overthrow the constitutional monarchy.

The reformist party and its prime minister candidate Pita Limjaroenrat covertly pushed an agenda to ¡°destroy¡± the form of government with the king as head of state, under the guise of a proposal to amend the controversial law, the court said.
