Thomas Aquinas,
Summa Theologiae — Question 67 - OF THE INJUSTICE OF A JUDGE, IN JUDGING…
“ 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. ”
