The doctrine has been attributed to Pope Innocent IV, who seems at least to have helped spread the idea of "persona ficta" as it is called in Latin. In canon law, the doctrine of "persona ficta" allowed monasteries to have a legal existence that was apart from the monks, simplifying the difficulty in balancing the need for such groups to have infrastructure though the monks took vows of personal poverty. Another effect of this was that, as a fictional person, a monastery could not be held guilty of delict due to not having a soul, helping to protect the organization from non-contractual obligations to surrounding communities. This effectively moved such liability to persons acting within the organization while protecting the structure itself, since persons were considered to have a soul and therefore capable of negligence and able to be excommunicated.
