In 1398, the Faculty of Theology of the University of Paris condemned holders of errors in faith and invokers of demons without finding them to be heretics. In 1399–1403, Marie Ducanech, tried for heresy by Bishop Pierre d’Ailly and a vice-inquisitor, successfully appealed against them to the archbishop of Rheims. On February 23, 1414, the bishop of Paris and inquisitor of France declared propositions of Jean Petit on tyrannicide to be errors in faith. Duke John of Burgundy successfully appealed against this sentence to Pisan Pope John XXIII, whose commission nullified it (1416). Even though the Council of Constance declared a tyrannicide article heretical (July 6, 1415), Cauchon ably used legal defenses against attacks on Petit’s articles, which were not further condemned. In 1428, Inquisitor Graverent tried Advocate Jean Ségueut and found him guilty of heresy. Ségueut could have appealed but did not. In 1430, Ségueut was tried by Official of Rouen Jean Basset and Inquisitor Graverent in a trial while obeying the rules of inquisitorial procedure: charges of heresy preceding interrogation, etc. In 1431, Inquisitor Graverent is occupied in a heresy case in Coutances where the defendant manages a papal appeal by outwitting Graverent and his bishop co-judge.
