Senator Pamela Wallin is threatening legal action against a move to suspend her without pay – something her lawyer calls  “an affront to Canadian democracy.”

Senate motions are set to be debated next week that would suspend Wallin, Mike Duffy and Patrick Brazeau  for the rest of the parliamentary session – for gross negligence.

Wallin’s lawyer says there is nothing in the audits or the resulting Senate reports  that make any mention of gross negligence.

He says if the motion against Wallin is passed Saskatchewan will be denied its constitutional right to one of its senators.

The three former members of the Conservative caucus were found by the Senate to have filed improper expense claims.
