Yes, although we've never misused this in the years I've been on the committee as far as I can recall, I've always been a little concerned by that clause in the middle that says “unless the substantive motion relates directly to business then under consideration”, because that's quite broad. You could be talking about the seal hunt, for example, and it could lead to some pretty significant substantive motions condemning the government, for example. Those kinds of things I think we want 48 hours' notice on.
As I say, I don't recall it being misused, but I'm not sure why we would want that clause in there, as we've never used it. There have been some non-substantive motions, things under consideration, and I think that's fine. They've been minor motions, perhaps. But I think I would feel more comfortable and I think our party would feel more comfortable if it read without that clause.
