The applicant challenged the constitutional validity of s. 12 of the National Security and Intelligence Committee of Parliamentarians Act, which disentitles committee members from claiming parliamentary privilege in proceedings arising from the disclosure of protected information.
The applicant argued that parliamentary privilege is constitutionally entrenched and cannot be abrogated by ordinary legislation without a constitutional amendment.
The court agreed, finding that s. 12 exceeds Parliament's authority to define privilege under s. 18 of the Constitution Act, 1867 and its amending powers under s. 44 of the Constitution Act, 1982.
Section 12 was declared ultra vires.
