What is required for a legislative veto to occur?

A legislative veto is a procedure that allows Congress to overturn executive actions without the approval of the President. For such a veto to occur, it typically requires a two-thirds majority in both houses of Congress. This supermajority is necessary because it serves as a significant check on executive power and ensures that there is broad bipartisan support for overturning executive actions. This level of consensus reflects the framers' intention to create a system of checks and balances within the government and prevents a simple majority from easily overriding executive decisions.

The other options do not satisfy the conditions for a legislative veto. A simple majority in one house, as suggested by one choice, would not be sufficient due to the requirement for significant consensus. Collaboration between the President and the Supreme Court, implied in another option, isn’t relevant to the process of a legislative veto, as it primarily concerns Congressional authority. A resolution passed only by both Congressional chambers does not correctly describe the necessary voting mechanism, which involves the specific requirement of a two-thirds majority.
