what is veto power

Veto power is the legal power to unilaterally stop an official action. In a political context, veto usually refers to the power of a chief executive to block or complicate the passage of a legislative bill by refusing to sign it into law. The veto power is defined in Article 1, Section 7 of the US Constitution. The president or monarch can veto a bill to stop it from becoming law. Congress can override the Presidents veto by passing the bill again with a two-thirds majority in both the Senate and House of Representatives. The veto allows the President to "check" the legislature by reviewing acts passed by Congress and blocking measures he finds unconstitutional, unjust, or unwise. In many countries, veto powers are established in the country's constitution. The executive power to veto legislation is one of the main tools that the executive has in the legislative process, along with the proposal power. In the United Nations’ Security Council, decisions are made with a majority of 9 votes of the 15 Council members’ votes. All decision is rejected if one of the five permanent members of the Security Council (China, United States, France, United Kingdom, Russia) makes use of its veto.
