How Many Members Are Required for a Quorum According to Robert's Rules of Order?

A quorum is declared if there are enough members present to conduct business. If a simple majority vote is required to pass motions, a majority of all members must be present to declare a quorum.

A quorum refers to the number of members present. The bylaws of an organization can stipulate a smaller or larger quorum. If a meeting does not have a quorum, there is no other alternative to adjourning and rescheduling. If a quorum is reached and all members were adequately informed of the meeting time and date, decisions reached by the quorum should be accepted as the decision of the entire body.
