the quorum, the bench of justices.

"A justice of the peace is of the quorum, when his commission expresses that he is one of those whose presence is necessary to constitute a bench, as at quarter-sessions. The term quorum is derived from the words used in the Latin form of the commission issued to justices of the peace; in which the expression occurred, quorum unum A.B. esse volumus, 'of whom we will that A.B. be one'"— (Imperial Dict.).
