Supermajority

In a situation where decisions are made by vote, the typical threshold to get anything done is 50%-plus-one. So...you need half of everyone’s vote plus one more to get a proposal passed.

However, that’s not always the case. Sometimes you need a super majority. The term refers to a different, higher threshold for getting a particular measure enacted.

An example in government comes from the vote needed to overcome a presidential veto. In that case, 2/3 of the House and Senate need to vote for something in order to overcome a veto. Not a majority...a super majority of 2/3.

In corporate terms, a company's bylaws will spell out the voting rules and procedures. Certain decisions may require super majority votes by shareholders.
