\Quo"rum\, n. [L., of whom, gen. pl. of qui who, akin to
E. who. See the Note below.]
Such a number of the officers or members of any body as is
competent by law or constitution to transact business; as, a
quorum of the House of Representatives; a constitutional
quorum was not present.
Note: The term arose from the Latin words, Quorum aliquem
      vestrum . . . unum esse volumus (of whom we wish some
      one of you to be one), which were used in the
      commission formerly issued to justices of the peace in
      England, by which commission it was directed that no
      business of certain kinds should be done without the
      presence of one or more of certain justices specially
      designated. Justice of the peace and of the quorum
      designates a class of justices of the peace in some of
      the United States.
