Quorum, << KWAWR uhm, >> is a certain number, or proportion, of members of an organization required by parliamentary law to be present before the group can transact business. In social organizations, the quorum is usually fixed by the constitution or bylaws, and may be less than a majority of the total membership. But in a legislative body, such as a city council or a state senate, a majority of the members is required in order to form a quorum. A majority is also usually required for a board of managers or trustees of a corporation.
In the United States Congress, legislative measures can be debated without a quorum. In a social organization, no business may be transacted without a quorum. In all cases, a quorum is required for a vote to be legal.
