What is the definition of quorum in a meeting?

The definition of quorum in a meeting refers to the minimum number of members required for a legal meeting to be conducted. This concept is crucial as it ensures that decisions made during the meeting are valid and have the backing of a representative portion of the group or organization present. Without reaching this minimum number, any decisions or votes taken could be challenged for lacking legitimacy. Quorum is often specified in an organization's bylaws and varies depending on the specific rules governing that group, ensuring that an adequate level of participation and consensus is achieved before proceeding with discussions or decision-making.
