Nicene and Post-Nicene Fathers, Ser. II, Vol. XIV:
The Canons of the Synods of Sardica, Carthage, Constantinople, and Carthage Under St. Cyprian, Which Canons Were Received by the Council in Trullo and Ratified by II. Nice.: Canon CVII

Canon CVII.  (Greek cx. continued.)

A Council concerning a bishop taking cognizance.

In the consulate of the most glorious Emperors Honorius for the VIIth time and Theodosius for the IIId, Augusti, xvii. Calends of July, a synod was held at Carthage in the basilica of the second region.  In this council it seemed good that no one bishop p. 496 should claim the right to take cognizance of a cause.  The acts of this council I have not here written down, because it was only provincial and not general.

Ancient Epitome of Canon CVII.

One bishop shall not claim for himself to take cognizance of a cause alone.

(Greek cxi.)

Synod against the Donatists.

After the consulate of the most illustrious Emperors Honorius for the VIIIth time and Theodosius for the IVth time, Augusti, xviii. Calends of July, at Carthage in the basilica of the second region.  In this council the bishops, Florentius, Possidius, Præsidius and Benenatus received legation against the Donatists, at that time at which a law was given that anyone might practice the Christian worship at his own will.
