I've been a member of this committee since 1999. We've said repeatedly that with respect to motions, it's possible to vote on specific parts of them. Really! We do that on a regular basis, at least here in the Standing Committee on Foreign Affairs and International Development, because we deal with complex issues. One day, a committee member tables a motion and the next day, someone requests an amendment of some kind. The committee then proceeds to vote on part or all of the motion.
We need to proceed carefully because we'll have to live with the consequences for a long time.
