The recent Motu Proprio "Mitis Iudex Dominus Iesus" promotes the differentiation of procedures in accordance with procedural economy and proximity. In this regard, the processus matrimonialis brevior coram Episcopo, governed by canons 1683-1687 M.I., happens to be the most important innovation. Starting from the question whether the procedure semplification that characterizes the processus brevior means abandoning, together with the model of contentious juridiction, the principle of indissolubility of marriage, the author gives possibile de jure condito answers and de jure condendo solutions, in order to protect, at the same time, the contentious nature of the procedure and the sacramental and indissoluble value of valid marriage.
