 This could potentially cause some difficulties, as a member of the University of Paris was being asked to investigate the verdict based on advice given by other members of the same university, some of whom were still alive and holding prominent positions within Church and State.Charles therefore was very cautious, limiting Bouillé's brief to a preliminary investigation in order to ascertain ‘the truth about the said process and in what manner it was conducted.’  Although there was a suspicion of an unjust condemnation, there was no suggestion at this stage of an inquiry leading to the Inquisition revoking its own sentence.Yet there were too many prominent people who had been willing collaborators in 1430 that had changed their allegiance once Charles had regained Paris and Rouen that had too much to lose for the proceedings against Joan to be reopened.
