Is it true that a member can move to postpone indefinitely to consider a main motion later?

The statement that a member can move to postpone indefinitely to consider a main motion later is not true. A motion to postpone indefinitely is used to kill a main motion without the possibility of discussing it further or bringing it back for consideration at a later time. This type of motion effectively removes the main motion from consideration altogether, rather than delaying it or postponing it for future discussion.

In parliamentary procedure, the intent of a motion to postpone indefinitely is to prevent further debate on the main motion. Therefore, if a member seeks to delay discussion on the main motion for future consideration, they would typically use a different motion, such as "postpone to a certain time," which explicitly allows for the motion to be discussed later. Thus, the answer indicating that it is false aligns with the rules of parliamentary procedure regarding the function and intent of a motion to postpone indefinitely.
