COALITION hopes that the Craig Thomson affair will bring down the Gillard government have been set back with the independent MP Bob Katter saying the courts, not Parliament, should judge the former Labor MP.

Mr Katter told the Sydney Morning Herald he would not support any vote suspending Mr Thomson from the Parliament, or forcing his resignation, until the matters against the MP had been heard by the court.

He accused the Coalition of double standards for pursuing Mr Thomson's alleged misdeeds of past years when it turned a blind eye for more than a decade to the alleged indiscretions of Peter Slipper when he was a Coalition MP.

''There's no qualitative difference in the actions of the Liberal Party and the Labor Party here,'' he said.
