Senator Michael Duffy sued the Senate of Canada for over $7 million in damages, alleging his suspension and denial of expenses were politically motivated, unconstitutional, and violated his Charter rights, despite his acquittal on criminal charges.
The Senate moved to dismiss the action, asserting parliamentary privilege.
The court granted the Senate's motion, finding that the Senate's decisions regarding member discipline, internal affairs, proceedings, and freedom of speech were protected by parliamentary privilege and thus immune from judicial review.
