Rules of Procedure (ROP)

Rules of Procedure (ROP) are the procedural rulebook a Model UN committee uses to structure debate. They define what motions are in order, the speaking time allotted, voting thresholds, and the powers of the chair. Most conferences adapt their ROP from the actual rules used by United Nations organs — particularly the Rules of Procedure of the General Assembly (UN Doc A/520/Rev.19) — but simplify them for a weekend-length simulation.

A typical MUN ROP covers:

• Roll call and quorum — establishing presence and the working majority.
• Setting the agenda — usually requiring a simple majority motion.
• Speakers List — the default mode of formal debate.
• Moderated and unmoderated caucuses — structured and informal debate blocks, with a delegate specifying duration, speaking time, and topic.
• Motions — to introduce a working paper, extend debate, divide the question, or move to a vote.
• Points — of order, parliamentary inquiry, personal privilege, and information.
• Voting procedure — including procedural votes (no abstentions), substantive votes, roll call voting, and the right to explain a vote.
• Closure of debate and adjournment.

Major circuits maintain distinct conventions. THIMUN procedure emphasizes consensus-building, pre-written resolutions, and lobbying, with fewer motions on the floor. Harvard/NMUN-style (sometimes called North American or "Harvard Rules") procedure is more motion-driven, featuring active caucusing and amendments from the floor. Crisis committees layer additional rules for directives, portfolio powers, and private notes.

The chair (or dais) is the final interpreter of the ROP, and rulings can typically be appealed under most rulesets. Delegates who master procedure gain a tangible advantage: knowing when to motion for an unmoderated caucus, how to divide the question on a contentious clause, or when to call for a roll-call vote can shape outcomes as much as substantive policy knowledge.
