Basically, the general test that we try to follow, and the practice that's followed in committees, is that the question is clear and that the members have all of the necessary information in order to come to a decision.
We're provided a package of amendments submitted by all the members. The chair reads the motion, shall Liberal, NDP or government motion whichever carry? That's the question he's putting. If there's any ambiguity or clarification required, the chair can point to the package and say that it's NDP-39, LIB-10, or whatever.
Aside from that, this is the practice in committees. I've been a legislative clerk for seven years. I've never seen that.
