Double majority
Type of voting procedure / From Wikipedia, the free encyclopedia
This article is about voting with two criteria of majority needing to be satisfied. For a system that requires more than 50% of the vote, see Majority and Absolute majority. For a system requiring more than an arbitrary percentage, set at greater than 50%, of the vote, see Supermajority.
A double majority is a voting system which requires a majority of votes according to two separate criteria. The mechanism is usually used to require strong support for any measure considered to be of great importance. Typically in legislative bodies, a double majority requirement exists in the form of a quorum being necessary for legislation to be passed.
