Except of course the obvious example:
Roma locuta est, causa finita est - Rome has spoken, the case is closed.
Now when dealing with Pelagianism Augustine wrote:
"Do you think these Fathers -- viz. Irenaeus, Cyprian, Reticius, Hilary, Ambrose [whom he had been quoting] are to be despised because they all belong to the Western Church, and I have mentioned no Eastern Bishop among them? What are we to do, since they are Greeks and we are Latins? I think that you ought to be satisfied with that part of the world in which our Lord willed to crown the chief (primus) of His apostles (Peter) with a glorious martyrdom. If you had been willing to hear blessed Innocent, the president of that Church, you would have long ago disengaged your perilous youth from the nets of the Pelagians. For what could that holy man answer to the African Councils, except what from of old the Apostolic See and the Roman Church with all others perseveringly holds? And yet you accuse his successor Zosimus of prevarication, because he would not allow the apostolic doctrine and the decision of his successor to be rescinded. But I say no more of this, that I may not, by the praise of him who condemned you, irritate your mind, which I desire rather to heal than to wound. See what you can reply to St. Innocent, who has no other view than have those into whose council I have introduced you (viz. the Fathers whom he had quoted); with these he sits also, though after them in time, before them in rank (etsi posterior tempore prior loco)....answer him, or rather our Lord Himself, whose words he alleges....What will you say? What can you answer? For it you should call blessed Innocent a Manichean, surely you will not dare to say it of Christ?"
and
Again St. Augustine relates that while Celestius refused at Rome to condemn the views which Paulinus accused him of holding, which was equivalent to denying the authority of the Council of Carthage in 411, from which he had appealed, yet "he did not dare to resist the letters of the blessed pope Innocent,"
and
"And the words of the venerable Bishop Innocent to the Council of Carthage....What more plain and clear than this sentence of the Apostolic See? To this Celestius professed to consent when....he answered: 'I condemn them according to the sentence of your holy predecessor Innocent.'...."What of that which the same Pope wrote in answer to the Bishops of Numidia also (because he had received letters from both Councils -- that is, both of Carthage and Milevis) does it not speak clearly of infants?"
Again : he speaks of Celestius seeming to be Catholic "when he answered that he consented to the letters of Pope Innocent, of blessed memory, by which all doubt about this matter was removed."
The following passage is also to be noted, written at the end of the Saint's life: "Let blessed Innocent also reply, the prelate of the Roman Church, who in answering (rescribens) the African Episcopal Councils in your case said: (he then quotes a passage from the letter to the Council of Carthage). 'Do you see what the Catholic Faith holds by her minister?' 'Videsne quid sapiat per ministrum suum catholica fides?'"
Once again, not explicitly stated, but implicitly accepted.
