 A veto may give power only to stop changes (thus allowing its holder to protect the status quo), like the US legislative veto, or to also adopt them (an "amendatory veto"), like the legislative veto of the Indian President, which allows him to propose amendments to bills returned to Parliament for reconsideration.The concept of a veto body originated with the Roman offices of consul and tribune of the plebs.There were two consuls every year; either consul could block military or civil action by the other.
