Security Council Procedures

Security Council procedure is fundamentally different from General Assembly procedure, and many experienced GA delegates make mistakes when they first enter an SC simulation. The most important differences to understand are size, informality, and the role of consultations.

The Council has only 15 members. This means there is no hiding. Every delegate is visible, every absence is noticed, and the chair knows exactly where each country stands. Speeches carry more weight because there are fewer of them. One strong intervention can shift the entire debate.

The Council operates largely through informal consultations rather than formal sessions. In the real UN, most SC business happens behind closed doors in the consultation room. In MUN, this translates to a much higher ratio of unmoderated to moderated caucus. Expect to spend more time negotiating face-to-face than giving speeches.

Voting in the Security Council

The voting rules are deceptively simple but strategically complex:

• Procedural matters: Nine affirmative votes required, no veto applies
• Substantive matters: Nine affirmative votes required, plus no P5 negative vote
• Abstentions: Do not count as negative votes (even for P5 members)
• Absence: Does not count as a negative vote

The distinction between procedural and substantive is critical. Deciding the agenda is procedural. Adopting a resolution is substantive. But determining whether something is procedural or substantive is itself substantive, meaning the P5 can veto the classification.

In practice, the Council often adopts resolutions by consensus (no vote, just the president's gavel) or by recorded vote where the breakdown matters politically even if the outcome is certain.

Procedure in MUN Security Council Simulations

Most MUN Security Council simulations adapt standard procedure with these features:

• Smaller committee, longer speaking times: Expect 90-120 second speeches instead of 60 seconds
• More unmoderated caucus: The ratio of unmod to moderated caucus is much higher than in GA
• Working papers are critical: With only 15 members, everyone needs to be involved in drafting
• No bloc system: Unlike GA where you might have 30 countries in your bloc, SC coalitions are fluid and small
• Presidential statements: The Council can issue a presidential statement (PRST) instead of a resolution, which is a weaker but still significant output

Some advanced simulations also include crisis elements, where the situation changes mid-session based on external events injected by the crisis team.

The Council's Toolbox of Outputs

Not every Council decision is a resolution. Knowing the hierarchy of outputs helps you pick the right instrument in a simulation.

Worked example: abstentions and the 1971 rule

Article 27 literally requires the 'concurring votes' of the permanent members, which could be read to mean a P5 abstention blocks adoption. In practice the Council decided otherwise from its earliest years, and the International Court of Justice confirmed the practice in its 1971 Namibia Advisory Opinion: a voluntary abstention by a permanent member does not prevent a resolution from passing. This is why a P5 state that dislikes a text but does not want to kill it can abstain — as China and Russia did on Resolution 1973 (2011) — letting the resolution pass while registering disapproval.
