On that, you are quite wrong. This is the relevant canon from c. AD 400:
35. The bishops of every country ought to know who is the chief among them, and to esteem him as their head, and not to do any great thing without his consent; but every one to manage only the affairs that belong to his own parish, and the places subject to it. But let him not do anything without the consent of all; for it is by this means there will be unanimity, and God will be glorified by Christ, in the Holy Spirit.36. A bishop must not venture to ordain out of his own bounds for cities or countries that are not subject to him. But if he be convicted of having done so without the consent of such as governed those cities or countries, let him be deprived, both the bishop himself and those whom he has ordained.
Oh come now, I find it difficult to understand how it is possible for anyone to claim the Apostolic Constitution ever purported to be Canon Law.
Further, and probably more important, the Apostolic Constitution is agreed upon as a forgery by both Catholic and Protestant scholars.
Even the "friendly" Catholic Encyclopedia finds it necessary to acknowledge this in it's opening pagagraph:
"A fourth-century pseudo-Apostolic collection, in eight books, of independent, though closely related, treatises on Christian , worship, and doctrine , intended to serve as a manual of guidance for the clergy , and to some extent for the laity."
CATHOLIC ENCYCLOPEDIA - APOSTOLIC CONSTITUTIONS
I repeat; There was no Canon Law in the early Church!
