There are two other ways to get things on the agenda if you miss the deadline:
- Convince me personally that the proposal is sufficiently important to be allowed onto the agenda.
- Convince 2/3 of the people voting at the Business Meeting that the proposal is sufficiently important to Suspend the Rules and allow it onto the agenda.
Given the new business already submitted and the constitutional amendments passed on to this year for ratification, I expect that either of the two ways of getting around the deadline are going to be hard sells. You're better off simply working within the rules.
Don't make me use this more often than necessary, please.
