I'm not sure I fully appreciate your question. If you are asking whether proceedings of a committee would be adversely affected by provisions in the Conflict of Interest Act, it's only to the extent that parliamentary secretaries might not be able to participate in the debate or vote at committee where they would be in conflict. Secondly, an individual member might be concerned about their position, depending on the matter before the committee, and because of a possible process that could go on out there affecting that member, the member might prefer to withdraw from the committee just to avoid it.
So it's that avoidance strategy that starts to develop amongst people who feel they might be at the wrong end of some process. The avoidance strategy is to just not attend, and find someone else to attend instead. So that fear can give rise to an intrusion, if you like, into the proceedings of the House or a committee.
