Silent procedure (also called tacit approval or approval by silence) is a decision-making method in which a proposal circulated to members is deemed adopted unless any member raises an objection before a stated deadline. Rather than requiring an affirmative vote, consent is inferred from silence.
The technique is widely used in real diplomatic practice — most prominently in the North Atlantic Council at NATO, where many routine and even substantive decisions are taken under silence procedure to preserve the appearance of consensus. The EU Council, the UN Security Council (for certain presidential statements and press elements), and sanctions committees also rely on it heavily. A member that wishes to block a text "breaks silence" before the clock runs out; the proposal then either fails, is renegotiated, or is put through normal procedure.
In Model UN, silent procedure is less codified but appears in two main forms:
- Draft circulation: chairs sometimes distribute a working paper or amendment and announce that, absent objection within a set time, it will be accepted onto the floor or merged with another draft.
- Crisis and specialised committees: directors may pass routine updates, press releases, or minor procedural rulings by silence to keep pace with the crisis arc.
Key features delegates should remember:
- A clear deadline must be announced (e.g., "silence until 14:00").
- A single objection is normally enough to break silence — it functions like a consensus rule.
- Breaking silence is procedurally cheap but politically costly; in NATO practice, states are reluctant to be seen as the lone obstructor.
- Silent procedure does not override rules of procedure that require a recorded vote, such as adoption of a resolution in most GA-style committees.
Used well, it speeds up housekeeping and signals consensus; used poorly, it lets controversial language slip through while delegations are distracted.
Example
In 2022, NATO repeatedly used silent procedure within the North Atlantic Council to approve assistance packages for Ukraine without holding formal votes.
Frequently asked questions
Consensus usually requires the chair to confirm no objections in the room; silent procedure runs against a clock, allowing members time to consult capitals or coalitions before the deadline expires.
