Which motion is used when the assembly wishes to return to the main motion after a subsidiary motion?

The motion used to return to the main motion after considering a subsidiary motion is known as "Previous Question." This motion is specifically designed to end the debate and bring the assembly back to the main topic of discussion. When the assembly feels that enough discussion has taken place regarding a subsidiary motion, they can call for the Previous Question to stop any further debate on that motion and move forward to vote on it or to return to the main motion.

In parliamentary procedure, the ability to use the Previous Question enhances efficiency and maintains order during discussions, allowing members to focus on the primary matters at hand without getting bogged down by prolonged deliberation on subsidiary issues. This is crucial in managing time and ensuring that decisions are made promptly.

Other options like "Postpone Indefinitely," "Commit or Refer," and "Amend" serve different purposes within parliamentary procedure, such as delaying the consideration of a motion, sending it to a committee for further examination, or altering the wording of a motion, respectively. These options do not facilitate the process of returning directly to the main motion after discussing a subsidiary one, which is why they do not address the question posed.
