Context

“etc. says: "There is no need of an accuser when the crime committed is notorious." In a case of denunciation, as stated above (Q. 33, A. 7) , the amendment, not the punishment, of the sinner is intended: wherefore when a man is denounced for a sin, nothing is done against him, but for him, so that no accuser is required. The punishment that is inflicted is on account of his rebellion against the Church, and since this rebellion is manifest, it stands instead of an accuser. The fact that the judge himself was an eye-witness, does not authorize him to proceed to pass sentence, except according to the order of judicial procedure.” source
