38 1.) An episcopal conference is, as it were, a council in which the bishops of a given nation or territory jointly exercise their pastoral office to promote the greater good which the Church offers mankind, especially through the forms and methods of the apostolate fittingly adapted to the circumstances of the age. 2. ) Members of the episcopal conference are all local Ordinaries of every rite-excluding vicar generals-and coadjutors, auxiliaries and other titular bishops who perform a special work entrusted to them by the Apostolic See or the episcopal conferences. Other titular bishops, legates of the Roman pontiff, because of their exceptional office in the territory are not de iure members of the conferences. Local Ordinaries and coadjutors hold a deliberative vote. Auxiliaries and other bishops who have a right to attend the conference will hold either a deliberative or a consultative vote, as the statutes of the conference determine. 3.) Each episcopal conference is to draft its own statutes for recognition by the Apostolic See. In these statutes, among other things, offices should be established which will aid in achieving its purpose more efficaciously, for example, a permanent board of bishops, episcopal commissions and a general secretariat. 4.) Decisions of the episcopal conference, provided they have been approved legitimately and by the votes of at least two-thirds of the prelates who have a deliberative vote in the conference, and have been recognized by the Apostolic See, are to have juridically binding force only in those cases prescribed by the common law or determined by a special mandate of the Apostolic See, given either spontaneously or in response to a petition of the conference itself. 5.) Wherever special circumstances require and with the approbation of the Apostolic See, bishops of many nations can establish a single conference. Communications between episcopal conferences of different nations should be especially encouraged in order to promote and safeguard the common good. 6.) It is highly recommended that the prelates of the Oriental Churches, promoting the discipline of their own churches in synods and efficaciously fostering works for the good of religion, should take into account also the common good of the whole territory where many churches of different rites exist. They should exchange views at inter-ritual meetings in keeping with norms to be given by the competent authority. II. The.
