The applicant, Senator Michael Dennis Duffy, sought an order requiring the Clerk of the Senate to produce an internal audit report prepared by Jill Anne Joseph regarding Senate expense policies and Senator Duffy's expense claims.
The Senate claimed parliamentary privilege over the document.
The court upheld the Senate's claim of privilege, finding that the internal audit report, prepared by a Senate employee and presented to a Senate subcommittee in camera, fell within recognized categories of parliamentary privilege including freedom of speech, exclusive cognizance over parliamentary proceedings, control over internal affairs, and disciplinary authority over members.
The court rejected arguments that the privilege had been waived and distinguished the case from R. v. Chaytor, which addressed expense claims themselves rather than internal audit reports.
