Clause by clause debate creates situations that do not come up in a General Assembly. These are the ones delegates hit most often.
Once the Council has voted on a clause, that clause is settled. The Council moves on. It does not reopen it later in the session.
This is the rule behind most of the trouble on this page. Everything you want done to a clause has to be done before its vote.
If you notice a mistake after the vote. The clause cannot be reopened. There is one route left. Once every operative clause has been debated and voted on, further clauses may be added as amendments. A new clause can be proposed at that point.
If the debate time on a clause is about to end and the Council is not finished, there are two routes.
Ask for the debate time to be extended. This is a motion to extend debate time. It is at the chair's discretion. It is not debatable. It needs a second if it comes from the floor, and the chair may refuse it. See Motion to extend debate time.
Ask to table the clause until the end of debate on that issue. The clause is set aside instead of being voted on now. The Council comes back to it at the end of debate on that issue.
Both have to be raised before the vote is taken.
Extending time on one clause takes time away from another. The chair is managing a whole session, not one clause. A refusal is not a judgement about your clause.
If you are unsure. Ask for an extension if a few more speeches would settle it. Ask to table the clause if a group of delegations needs to go and negotiate the text.
An amendment of the first degree is taken against the clause being debated, and only that clause. An amendment aimed at a clause that is not on the floor is out of order.
If your change affects more than one clause. An amendment may cover more than one clause when the change has to be made in several places to make sense. Renaming a body that appears in four clauses is the standard example. See Amendment edge cases.
If a clause has already been amended. It can be amended again in two situations only. The new amendment touches something not yet discussed. Or it is needed to make the clause fit later changes. See Amending an already amended clause.
An amendment of the second degree may only be submitted during time against the first degree amendment. Debate on it does not count against the time for the first degree amendment.
If the second degree amendment passes, the first degree amendment passes automatically, and the two are counted as one. If it fails, debate on the first degree amendment resumes.
An amendment of the third degree is out of order. That is true in the Security Council as well as everywhere else.
See Amendment of the second degree.
If you have done MEDIMUN before. This changed. The older rule allowed second degree amendments only in the Security Council. They are now allowed generally.
The preambulatory clauses are voted on together. If that bloc fails, the resolution fails with it, unless the house resolves the problem first. This is covered in full in Preambulatory clauses en bloc.
An amendment about spelling or grammar should not be debated. The chair makes the change directly and tells the house.
Do not spend a clause's debate time on a comma.
While a vote is being taken, all points are out of order. The one exception is a point of order about the conduct of the vote itself. See Point of order.
If you are unsure. If you do not know whether your point is in order, wait for the pause. Points are taken when the speaker yields, to points of information, to another delegation, or to the chair. No point interrupts a speaker, except a point of personal privilege about audibility. See Points overview.
