No RVIs

In Model UN and some parliamentary debate circuits, an RVI (Right of Reply, sometimes rendered "Right of Personal Privilege" or in policy debate as an "independent voting issue") allows a delegate who feels their nation, character, or representation has been impugned to respond outside the normal speaking order. When a chair, moderator, or speaker announces "No RVIs," they are signaling that for the duration of that moderated caucus, speech, or session, such replies will not be entertained.

The convention serves several practical functions:

• Time discipline. Rights of Reply interrupt the speakers list and can derail tightly scheduled debate, especially in crisis committees or short moderated caucuses.
• Tone management. By foreclosing replies, chairs discourage personal sparring between delegates and keep focus on substantive policy.
• Procedural clarity. In fast-moving debate, chairs sometimes pre-empt motions they do not intend to recognize, so delegates know not to raise placards mid-speech.

The phrase is borrowed loosely from policy and Lincoln-Douglas debate, where "no RVIs" is a stock theory position meaning the opponent cannot win the round solely by defeating a procedural argument (theory or topicality). In MUN usage, however, the meaning is narrower and procedural rather than strategic.

"No RVIs" is not a formal rule under UN procedure. The actual UN General Assembly Rules of Procedure (Rules 66–73 on conduct of debate) provide for points of order and explanations of vote, and a Right of Reply exists in GA practice (see Rule 73 and longstanding plenary practice), exercised after the speakers list concludes. MUN conferences such as NMUN, WorldMUN, and Harvard MUN each publish their own rules of procedure, and whether RVIs are permitted, restricted, or banned varies by conference and committee. Delegates should consult the specific rulebook before assuming the convention applies.
