Quorum

In contrast, a plenum is a meeting of the full (or rarely nearly full) body. A body, or a meeting or vote of it, is quorate if a quorum is present (or casts valid votes). The term quorum is from a Middle English wording of the commission formerly issued to justices of the peace, derived from Latin quorum, "of whom", genitive plural of qui, "who". As a result, quora as plural of quorum is not a grammatically well-formed Latin-language construction. In modern times, a quorum might be defined as the minimum number of voters needed for a valid election. Quorums are often part of parliamentary procedure. According to Robert, each assembly determines the number of members that constitutes a quorum in its governing documents (such as in its constitution, charter, bylaws or standing orders). The quorum may also be set by law.
