[IDEM libro primo opinionum. ] §2.1.17.prPraetor sicut uniuersam iurisdictionem mandare alii potest, ita et in personas certas uel de una specie potest, maxime cum iustam causam susceptae ante magistratum aduocationis alterius partis habuerat.
[THE SAME, Opinions, Book I.] Just as a praetor can delegate his entire jurisdiction to another, so he can also do so with respect to specific persons or concerning a single department, especially when he had a just cause because of having undertaken the advocacy of one of the parties before entering upon his magistracy.
