A group of red-shirt community radio operators who led a protest against the Constitution Court yesterday petitioned the same court to consider if three of its judges have violated the constitution.
They filed the petition after ending 17 days of protest against the judges on Wednesday.
The group is led by Pongpisit Kongsena, Charn Chaiya and Sornrak Malaithong. Nuengdin Wimutthinant, the group's lawyer, submitted the petition on their behalf.
The petition asked six of the court judges to look into whether three of their fellow judges had violated Section 68 of the constitution by accepting a petition submitted by Senator Somchai Sawaengkarn.
Section 68 pertains to acts that could undermine the constitutional monarchy or grab power through unconstitutional means.
On April 3, the court voted three to two to accept the complaint. The three judges are Jarun Pukditanakul, Jaroon Intharajarn and Supoj Khaimuk. The charter court has nine judges.
The senator had asked the court to rule on the legality of an attempt by 312 MPs and senators to amend Section 68 of the constitution.
The group also accused the three judges of violating Section 3 of the constitution which deals with the separation of legislative, executive and judicial powers.
They argued that by accepting the petition, the charter court was trying to interfere with the government's attempts to amend Section 68. They said law changes are the duty of parliamentarians and the court should not interfere.
The group also filed complaints with Thung Song Hong police accusing the three judges of committing treason. Mr Nuengdin said similar complaints will also be filed with stations nationwide.
Meanwhile, Amnuay Klangpha, a Pheu Thai MP for Lop Buri and government chief whip, yesterday said the three charter amendment bills were unlikely to be on the House agenda when the extraordinary session opens on May 29.
He said the special session would focus on the 2014 budget bill debate and there would be insufficient time to deliberate charter amendment bills.
