Security Council Specific Procedures
The Security Council operates under unique procedural rules that differ sharply from the General Assembly. Master the veto, consensus practice, and SC-specific mechanisms.
Security Council Composition and Voting
The Security Council has 15 members: 5 permanent (P5 — United States, United Kingdom, France, Russia, China) and 10 non-permanent members elected for two-year terms by the General Assembly. This structure creates a fundamentally different procedural dynamic than the GA's one-country-one-vote system.
Voting rules (Article 27 of the UN Charter):
- Procedural matters require 9 affirmative votes out of 15 (no veto applies)
- Substantive matters require 9 affirmative votes including the concurring votes of all 5 permanent members
- A negative vote by any permanent member on a substantive matter is a veto and kills the resolution
The abstention practice: The Charter says 'concurring votes' of the P5 are required, which literally means all five must vote yes. But since 1946, the Council has interpreted abstention by a permanent member as not constituting a veto. This practice — never formally codified — means a P5 member can signal displeasure without blocking action. China frequently abstains rather than vetoes, using this distinction strategically.
The double veto: A permanent member can veto not just a resolution but also the preliminary question of whether an issue is procedural or substantive. If the Council must decide whether a veto applies, that preliminary decision is itself subject to veto. This 'double veto' is rare but theoretically available.
