What does a reconsider motion do to a previously decided motion?

The function of a reconsider motion is to allow the assembly to revisit a motion that has already been decided. By treating the motion as if it was never voted on, it essentially opens the door for the membership to discuss the issue anew and potentially change the outcome of the previous vote. This aspect of parliamentary procedure is crucial as it provides a structured way for members to correct any decisions made that may need revisiting due to new information, changes in opinion, or other relevant factors.

In this context, the other options do not accurately describe the effect of the reconsider motion. While it does allow for debate again, it does not directly state that it negates the previous motion; rather, it allows for the possibility of changing the decision. Thus, while the reconsider motion prompts fresh discussion, its purpose is not to negate but to review and potentially alter the original decision. It does not completely alter the outcome of the previous vote until a new decision is reached.
