Which of the following is a rule for the subsidiary motion to Postpone to a Certain Time?

The subsidiary motion to Postpone to a Certain Time is properly used to delay consideration of a main motion to a specified future time. One key rule regarding this motion is that it is out of order when another member has the floor. This means that the motion cannot be introduced while a member is currently speaking, as the rules of parliamentary procedure stipulate that a person has the right to finish their speech without interruption.

Allowing the motion to be made while another member is speaking would disrupt the order of proceedings and hinder effective communication during the meeting. Therefore, following this rule ensures that all members have an uninterrupted opportunity to present their thoughts, maintaining decorum and respect within the meeting.
