Whether a judge may condemn a man who is not accused?

Objections

Objection 1 : It would seem that a judge may pass sentence on a man who is not accused. For human justice is derived from Divine justice. Now God judges the sinner even though there be no accuser. Therefore it seems that a man may pass sentence of condemnation on a man even though there be no accuser.
Objection 2 : Further, an accuser is required in judicial procedure in order that he may relate the crime to the judge. Now sometimes the crime may come to the judge's knowledge otherwise than by accusation; for instance, by denunciation, or by evil report, or through the judge himself being an eye-witness. Therefore a judge may condemn a man without there being an accuser.
Objection 3 : Further, the deeds of holy persons are related in Holy Writ, as models of human conduct. Now Daniel was at the same time the accuser and the judge of the wicked ancients (Dan. 13). Therefore it is not contrary to justice for a man to condemn anyone as judge while being at the same time his accuser.
