Approval by acclamation is a procedural shortcut used in Model UN and many real deliberative bodies in which the chair declares a motion, draft, or candidate adopted without conducting a formal recorded or roll-call vote, provided no delegate objects. The chair typically states something like, "If there are no objections, the resolution will be adopted by acclamation," and pauses briefly. If silence follows, the item passes; if a single delegate calls out an objection, the chair must revert to a standard substantive vote.
The mechanism is used in MUN to save committee time on items where consensus is obvious — for example, adopting an uncontroversial agenda, approving the report of a working group, electing a sole candidate for a chair or rapporteur role, or passing a humanitarian resolution that drew no "no" votes during informal consultations. It mirrors practice in the actual UN General Assembly and Security Council, where many resolutions are adopted "without a vote" once sponsors confirm there is no opposition.
Key features delegates should remember:
- Unanimity is required only in the negative sense — no one needs to actively say "yes," but a single objection blocks acclamation.
- It is not the same as a unanimous vote. Acclamation produces no tally, so abstentions and yes votes are not recorded. Delegates who want their position on the record should object and request a roll call.
- Substantive matters in Security Council simulations still respect the veto logic: a P5 objection halts acclamation just as it would block a vote.
- Amendments can also be approved by acclamation if all sponsors and the body agree, which is common for friendly amendments.
Rules of procedure vary between conferences. THIMUN-style committees use acclamation routinely; Harvard-style and NMUN committees tend to require explicit votes on substantive resolutions but allow acclamation on procedural matters and elections. Delegates should always check the conference's published rules before assuming acclamation is available.
Example
At a 2023 THIMUN conference, the General Assembly Third Committee adopted a draft resolution on girls' education by acclamation after no delegation rose to object.
Frequently asked questions
Yes. Acclamation requires the absence of objection, so one delegate calling out an objection forces the chair to hold a normal substantive vote.
