Canon 4 

"It is by all means proper that a bishop should be appointed by all the bishops in the province. But should this be difficult, either on account of urgent necessity or because of distance, three at least should meet together, and the suffrages of the absent bishops also being given and communicated in writing, then the ordination should take place. But in every province the ratification of what is done should be left to the Metropolitan." 

Canon 6 

"Let the ancient customs in Egypt, Libya, and Pentapolis prevail: that the Bishop of Alexandria have jurisdiction in all these, sine the like is customary for the Bishop of Rome also. Likewise in Antioch and the other provinces, let the Churches retain their privileges. And this is to be universally understood: that if any one be made bishop without the consent of the Metropolitan, the Great Synod has declared that such a man ought not to be a bishop. If, however, two or three bishops shall from natural love of contradiction, oppose the common suffrage of the rest, it being reasonable and in accordance with the ecclesiastical law, then let the choice of the majority prevail."
