evidence: If a member genuinely missed something after turning their mind to the interests they hold, that would not be a contempt. However, if a member knew of an interest and decided not to declare it, and if the interest were subsequently established to be definitively declarable, then the member would have knowingly failed to declare an interest.[99] [...] However, before participating in parliamentary business in which a member has a financial interest, they must declare that interest to the House or committee.[126] Failing to do so may be treated as a contempt of the House.[127] But the validity of the business transacted by the House or committee (for example, a question asked by the member) is not affected by the member’s failure to declare a financial interest.[128] [...] The obligation to declare a financial interest lies with the member who holds it; other members cannot impose an obligation on the member to take any action by alleging that a financial interest is held.[144] If a member holds a financial interest and fails to declare it, the issue may be raised as a matter of privilege. If there is a dispute as to whether there is a financial interest, the Speaker decides the matter, and the Speaker’s decision is final.[145] In any subsequent consideration of the matter by the Privileges Committee, the committee would be bound by the Speaker’s finding on whether a financial interest existed.
