Final answer:
The motion to postpone to a certain time in parliamentary procedure does not directly 'kill' a motion but can effectively delay it indefinitely. If strategically used, this delay could prevent the motion from being voted upon, indirectly 'killing' it.
Step-by-step explanation:
The question refers to a procedural tactic used within a legislative or other decision-making body. Specifically, it asks if the motion to postpone to a certain time can be used to effectively 'kill' or indefinitely delay a motion. In parliamentary procedure, a motion to postpone to a certain time (or a definite time) is a subsidiary motion that sets aside a main motion until a particular time or until certain conditions are met. This action itself does not 'kill' a motion, but it does delay its consideration.
However, if the motion to postpone is used strategically and the postponed time is never reached or the conditions are never met, it can effectively prevent a motion from coming up for a vote. This could be seen as a way to indirectly 'kill' a motion without a direct vote on its merits. It is important to understand that this can be a contentious tactic and could be challenged by members of the body who wish to see the main motion discussed or decided upon.
