The Fourth Council of Constantinople-Canon #10:
As divine scripture clearly proclaims, Do not find fault before you investigate, and understand first and then find fault, and does our law judge a person without first giving him a hearing and learning what he does? Consequently this holy and universal synod justly and fittingly declares and lays down that no lay person or monk or cleric should separate himself from communion with his own patriarch before a careful enquiry and judgment in synod, even if he alleges that he knows of some crime perpetrated by his patriarch, and he must not refuse to include his patriarch's name during the divine mysteries or offices.
In the same way we command that bishops and priests who are in distant dioceses and regions should behave similarly towards their own metropolitans, and metropolitans should do the same with regard to their own patriarchs. If anyone shall be found defying this holy synod, he is to be debarred from all priestly functions and status if he is a bishop or cleric; if a monk or lay person, he must be excluded from all communion and meetings of the church until he is converted by repentance and reconciled.[/u]
