UN Security Council — Guide & Rules of Procedure

1. Introduction

The United Nations Security Council (UNSC) in Model United Nations simulates the UN’s most powerful organ — the only body whose decisions are legally binding under international law. It is responsible for maintaining international peace and security, addressing conflicts, authorizing peacekeeping missions, and enforcing sanctions under the UN Charter’s Chapter VII.

2. Mandate & Objectives

Peacekeeping Operations

Order of PrecedenceN/AN/APriority: 1) Points → 2) Procedural Motions → 3) Substantive Debate. The Chair’s ruling is final.
Conduct of DebateN/AN/ADelegates must remain diplomatic, address others in third person, and maintain formal language.

7. Delegate Preparation & Strategy
  • Understand Your Role: Distinguish between Permanent and Non-Permanent members — veto power alters strategy entirely.
  • Research Deeply: Know your country’s real UNSC voting history, alliances, and past positions on the topic.
  • Veto Management: Anticipate potential P5 opposition and draft language that avoids triggering a veto.
  • Negotiation Tactics: Build coalitions early. Non-Permanent members succeed by coordinating blocs and leveraging abstentions.
  • Resolution Drafting: Write enforceable, specific operative clauses that survive legal scrutiny under Chapter VII.
8. Expected Outcomes
  • One or more binding resolutions addressing global security threats.
  • Deep understanding of veto dynamics and real-world diplomatic constraints.
  • Strengthened negotiation, drafting, and crisis-management skills.
  • Exposure to strategic consensus-building in high-pressure multilateral settings.
9. Conclusion

The Security Council demands precision, strategy, and political realism. Delegates must balance power politics with collective security, negotiate under the constant shadow of the veto, and craft resolutions that both reflect global consensus and carry legal authority. Mastering this committee means mastering the art of diplomacy under pressure.
