Gregory was also asked to arbitrate during his journey to Francia in 833 the case against Aldric of Le Mans, who was being forced out of his see by partisans of Lothair. On 8 July 833 Gregory wrote to the bishops of “Gaul, Europe and Germany” declaring that Aldric had every right to appeal to the pope, and that until the pope had issued a judgement one way or the other, no-one could pass a sentence against him. Further, that this mandate had to be obeyed in order to remain in communion with the Roman church. The letter together with the restoration of Louis allowed Aldric to remain in his see for some time.
