[CALLISTRATUS libro primo de cognitionibus. ] §1.18.9.prGeneraliter quotiens princeps ad praesides prouinciarum remittit negotia per rescriptiones, ueluti 'eum qui prouinciae praeest adire poteris' uel cum hac adiectione 'is aestimabit, quid sit partium suarum', non imponitur necessitas proconsuli uel legato suscipiendae cognitionis, quamuis non sit adiectum iectum 'is aestimabit quid sit partium suarum': sed is aestimare debet, utrum ipse cognoscat an iudicem dare debeat.
[CALLISTRATUS, in the first book on extraordinary investigations.] In general, whenever the emperor refers cases to the governors of provinces by rescripts, such as 'you will be able to approach the person who is in charge of the province,' or with this addition, 'he shall evaluate what is consistent with his duty,' no necessity of undertaking the investigation is imposed upon a proconsul or a legate, even if 'he shall evaluate what is consistent with his duty' has not been added: but he ought to evaluate whether he himself should investigate or whether he should appoint a judge.
