Christus Dominus 40. Therefore, in order to accomplish these aims this sacred synod decrees as follows: 1) The boundaries of ecclesiastical provinces are to be submitted to an early review and the rights and privileges of metropolitans are to be defined by new and suitable norms. 2) As a general rule all dioceses and other territorial divisions that are by law equivalent to dioceses should be attached to an ecclesiastical province. Therefore dioceses which are now directly subject to the Apostolic See and which are not united to any other are either to be brought together to form a new ecclesiastical province, if that be possible, or else attached to that province which is nearer or more convenient. They are to be made subject to the metropolitan jurisdiction of the bishop, in keeping with the norms of the common law. 3) Wherever advantageous, ecclesiastical provinces should be grouped into ecclesiastical regions for the structure of which juridical provision is to be made.
