The Canons of the Councils of Ancyra, Gangra, Neocæsarea, Antioch and Laodicea, which Canons were Accepted and Received by the Ecumenical Synods 74Canon XI.

If any bishop, or presbyter, or any one whatever of the canon shall presume to betake himself to the Emperor without the consent and letters of the bishop of the province, and particularly of the bishop of the metropolis, such a one shall be publicly deposed and cast out, not only from communion, but also from the rank which he happens to have; inasmuch as he dares to trouble the ears of our Emperor beloved of God, contrary to the law of the Church. But, if necessary business shall require any one to go to the Emperor, let him do it with the advice and consent of the metropolitan and other bishops in the province, and let him undertake his journey with letters from them.
