12 These statutes have been discussed at length and with great care by both parties. The outcome of these discussions is that the Diocesan Associations which are contemplated by this plan are quite different from those which Pius X condemned and had refused permission to organize. This conclusion takes on added certainty due to the facts that these statutes do not depend, either necessarily or directly, upon the law condemned by Pius X, and that the functioning of these Associations must always be in conformity with Canon Law. In case of difficulties or conflicts, those in charge of the Associations have the right and the duty of informing this Apostolic See.
