What Mr. Kenney is bringing up is the issue raised in Standing Order 115, that when a legislative committee is sitting on a certain subject matter—in this case it's Bill C-2, the bill on accountability—any other committee that has similar subjects that it is mandated to deal with shall step down, in the sense that they shall not sit at the same time.
How you interpret that is up for discussion with members. If we take the strict interpretation, this committee cannot meet when Mr. Tilson's committee is sitting. We can find an alternate time for this committee to sit when Mr. Tilson's committee is not sitting, but that would be jumping out of our block that is agreed to by the whips of the various parties, and it could cause us to be bumped out of any room we may book.
