In Model UN, amendments to be voted en bloc is a procedural shortcut used during the amendment phase of a draft resolution. Rather than voting on each proposed change one by one, the chair (or a delegate via motion, depending on the conference's rules of procedure) groups multiple amendments together so the committee disposes of them in a single vote.
The mechanism is almost always reserved for friendly amendments — changes accepted by all original sponsors of the draft resolution — or for a package of uncontroversial technical edits. Because no delegate formally objects, bundling them saves committee time that would otherwise be spent on repetitive roll calls or placard votes. Most rulebooks, including variants of the THIMUN and Harvard-style procedures, give the dais discretion to adopt friendly amendments by acclamation or to batch them en bloc.
Unfriendly amendments — those opposed by at least one sponsor — are typically not eligible to be voted en bloc, because each requires a separate substantive debate, a speakers' list for and against, and an independent vote. Bundling contested changes would deprive delegations of the right to take a distinct position on each one.
Procedurally, a delegate may rise to a motion to vote on amendments en bloc, which usually requires a simple majority and is debatable in some rulebooks, non-debatable in others. If passed, the amendments are read into the record (or referenced by number) and a single yes/no vote determines whether the entire package is incorporated into the working draft.
Key practical points for delegates:
- Confirm your conference's specific rules — UN4MUN, THIMUN, NMUN, and Harvard WorldMUN handle amendments differently.
- En bloc voting applies to amendments, not to operative clauses of the resolution itself (though some rulebooks permit en bloc clause voting separately).
- If you object to even one item in the bundle, you should vote against the entire package or move to divide the question before the en bloc vote occurs.
Used well, the tool accelerates closure; used carelessly, it can mask substantive disagreements.
Example
At NMUN New York 2023, the chair of the GA Third Committee grouped six friendly technical amendments on a draft resolution concerning indigenous rights and put them to a single en bloc vote, which passed by acclamation.
