Motion for a Moderated Caucus

A motion for a moderated caucus is one of the most frequently used procedural tools in Model UN. It temporarily suspends the general speakers list so that delegates can debate a narrower sub-issue under the chair's direction, with each speaker recognized individually for a fixed speaking time.

To raise the motion, a delegate is recognized by the chair and typically states four elements:

• the total duration of the caucus (e.g., 10 minutes),
• the individual speaking time per delegate (e.g., 1 minute),
• the topic of the caucus (e.g., "humanitarian corridors in conflict zones"), and
• optionally, a brief rationale.

The motion is procedural, requires a simple majority to pass, and is generally not debatable, though dais practice varies. When multiple moderated caucus motions are on the floor, most rulebooks (including those used by NMUN, Harvard WorldMUN, and HNMUN) instruct the chair to vote on them in order of most disruptive first — usually meaning the longest total time, or the motion that deviates most from the default speakers list.

Moderated caucuses sit between two other formats. They are more structured than an unmoderated caucus, where delegates leave their seats to negotiate freely, and less rigid than the general speakers list, where speeches address the topic as a whole. Their purpose is to focus debate: chairs often encourage moderated caucuses when bloc positions are unclear, when a working paper needs public scrutiny, or when a specific clause is contested.

Delegates who do not wish to speak when called typically pass or yield their time back to the chair; yields to other delegates or to questions are usually not permitted in a moderated caucus, distinguishing it from substantive speeches on the speakers list. Effective use of moderated caucuses — proposing them at the right moment and on the right sub-topic — is widely considered a marker of strong procedural command and is rewarded by many awards rubrics.
