This was the beginning of the -provocatio-, which for that reason was especially permitted not to the transgressor who had refused to plead guilty and had been convicted, but to him who confessed his crime and urged reasons in palliation of it.

In the ordinary course of law the perpetual treaty concluded with a neighbouring state might not be broken--unless the burgesses deemed themselves released from it on account of injuries inflicted on them.

Hence it was necessary that they should be consulted when an aggressive war was contemplated, but not on occasion of a defensive war, where the other state had broken the treaty, nor on the conclusion of peace; it appears, however, that the question was in such a case addressed not to the usual assembly of the burgesses, but to the army.

Thus, in general, it was necessary to consult the burgesses whenever the king meditated any innovation, any change of the existing public law; and in so far the right of legislation was from antiquity not a right of the king, but a right of the king and the community.

In these and all similar cases the king could not act with legal effect without the cooperation of the community; the man whom the king alone declared a patrician remained as before a non-burgess, and the invalid act could only carry consequences possibly -de facto-, not -de jure-.
