veto

A veto is the power of a person or authority, like a president or a governor, to reject or refuse a decision or law that has been made by a legislative body, such as Congress or a parliament. When they issue a veto, they are effectively saying they do not agree with the proposal and prevent it from becoming official law unless the legislative body overrides the veto, usually with a higher majority. The veto serves as a check on the legislative process, ensuring that the executive has a role in approving or blocking legislation.
