In 1215, John appointed Sir Geoffrey Luttrell to be his sole agent in negotiations with regard to the dower of Queen Berengaria, commissioning him at the same time to join with the Archbishops of Bordeaux and Dublin in denouncing to the Pope the rebellious barons who had recently extorted the Great Charter of English Liberties. In one of the documents connected with this business, he is styled " 'nobilis vir' ". His mission was so far successful that Innocent the Third annulled the Charter, suspended the Archbishop of Canterbury, and excommunicated the barons, but it is uncertain whether Sir Geoffrey Luttrell was the one of those who conveyed the papal bull from Rome to England.
