It all depends on the level of authority. Again, we've had these debates in the drafting of the other policy. I think the whips are key to a certain extent, because they're already responsible for the discipline within their party. It does raise the question of what to do when it's an independent member or an unrecognized party.
I think the key is to have a figure of authority who actually can take sanctions. We know that the party can exclude members from the caucus, so that is a sanction. The bigger piece is if it's bigger than the party. What if it's between members of different parties? Then you get into a bigger debate.
I think the key is who will be the person who will make the decision and have the power to make a sanction against a member.
