The Cyclopedic Law Dictionary
An entering upon the duties under a commission, or commencing to act under a commission, is so termed. Thus, the judges of assize and nisi prius derive their authority to act under or by virtue of commissions directed to them for that purpose; and, when they commence acting under the powers so committed to them, they are said to open the commissions'; and the day on which they so commence their proceedings is thence termed the "commission day of the assizes." _ Brown.
