Supermajority
A voting threshold higher than a simple majority — typically two-thirds or three-fifths — required for certain significant decisions.
Explanation
A supermajority is a qualified majority requiring more than 50%+1 to pass. Common thresholds include two-thirds (66.7%) and three-fifths (60%). Supermajorities are typically required for constitutional amendments, override of executive vetoes, removal of officials through impeachment, and ratification of treaties. The logic is that fundamental changes to the constitutional order should require broad consensus, not just a slim electoral majority. In the U.S. Senate, a three-fifths supermajority (60 votes) is needed to end a filibuster. Germany's Basic Law requires a two-thirds supermajority of both Bundestag and Bundesrat for constitutional changes.
