Bamberg, Dom

Guilielmus Durantis, Speculum iuris (Basel: 1574) Pars III, De inquisitione Vltimo (p. 42):

Abbas non privabit eum defensione, quae excommunicato, et etiam diabolo, si in iudicio adesset, non negaretur (The abbot shall not deprive him from his defense, which is due to an excommunicant and even to the devil, if he would be present in court).
