I'm happy to answer that. The nature of the requirements that would be associated with receiving that briefing is that he could not use that information in any way to do anything. If a person is briefed, and they are required as a condition of that briefing to tell no one, to action the information in no way, what possible action could be taken?
We have a law that applies to every party, although I'm not sure it is being used. The Reform Act requires every caucus to take a vote at the beginning of Parliament on a mechanism whereby caucus members could be involved in a decision about caucus membership. Let's suppose that a leader becomes aware that there's a concern. They cannot bring that issue to their caucus. They can't bring that issue to the national campaign director. They can't bring it anywhere.
What we need is a process for accountability, not a secret briefing with the condition that you can do nothing with the information. It's not effective.
