In the former view, while it is often admitted that other Orthodox churches might cut off communion with an erring patriarch, that break in communion is not regarded as truly binding. Thus, individual sovereignty is absolutely maintained. In the latter view, however, autocephalous churches are truly answerable to one another, and the tribunal which exercises this accountability, when invited by appeal, is the Ecumenical Patriarchate. Both positions have difficulty when worked out in practice, as there is always the possibility that a given patriarch or Ecumenical Patriarch may act in a tyrannical manner. Historically, though, tyrannical patriarchs have been deposed, typically led by either the Ecumenical Patriarch himself (in the case of other patriarchs) or by the clergy of that patriarchate (in the case of the [[deposition ]] of their own patriarch), often in conjuction with a patriarch from a neighboring autocephalous church, such as [[Church of Alexandria|Alexandria]].
