Jean Colombel, Columbelli, a cleric of Lisieux, was bachelor of arts in 1403, Of law in 1415, and figured in 1420 among the licentiates at Paris where he had for teacher another of Jeanne's judges, Jean Garin, dean of the Faculty of Law.

Promoter of the diocese at Rouen in 1423 and 1424, he denounced those who had seized the revenues of the archbishopric during the vacancy of the See, proclaiming loudly words that wounded various canons; and he was imprisoned for this.

Jean Colombel was promoter for the ecclesiastical court of Rouen from 1423 to 1429. He was curé of Valliquierville in 1429 and he exchanged this benefice for that of Saint Vivien of Rouen which was held at that time by Jean Secart, licentiate in law, one of those present at the Trial.

Colombel must have died intestate on November 12, 1437. He was then described as canon and scholastic of Lisieux, a title which he obtained, presumably, from Pierre Cauchon.

In his final judgment concerning Jeanne, Jean Colombel decided as did the Abbot of Fécamp, Gilles de Duremort.
