Final answer:
In legislative procedures, once an objection to consideration has been adopted, it is usually final and cannot be reconsidered. Specifically regarding a President's veto, a bill can be reconsidered and passed by a two-thirds majority in both houses to become law despite the veto.
Step-by-step explanation:
Can a vote adopting an objection to the consideration be reconsidered? Generally, in legislative procedures, once an objection to the consideration of a question has been adopted, it cannot be reconsidered. This is because an objection to consideration is a final decision on not addressing the matter at hand. However, procedures may vary based on specific rules of the legislative body.
When it comes to the President's veto, if the president returns a bill with objections, the bill's originating house will enter these objections and proceed to reconsider the bill. Following this, if two-thirds of the House agree to pass the bill, despite the objections, it is then sent to the other house for a similar reconsideration. If both houses pass the bill with a two-thirds majority, it can override the presidential veto and become law without further consideration of the President's objections.
