It is unnecessary to describe with any minuteness the mode of administering criminal justice under the Roman Empire, but it is to be noted that both its theory and practice have had powerful effect on modern society. The Emperors did not immediately abolish the Quaestiones, and at first they committed an extensive criminal jurisdiction to the Senate, in which, however servile it might show itself in fact, the Emperor was no more nominally than a Senator like the rest. But some sort of collateral criminal jurisdiction had been claimed by the Prince from the first; and this, as recollections of the free commonwealth decayed, tended steadily to gain at the expense of the old tribunals. Gradually the punishment of crimes was transferred to magistrates directly nominated by the Emperor and the privileges of the Senate passed to the Imperial Privy Council, which also became a Court of ultimate criminal appeal. Under these influences the doctrine, familiar to the moderns, insensibly shaped itself that the Sovereign is the fountain of all Justice and the depositary of all Grace. It was not so much the fruit of increasing adulation and servility as of the centralisation of the Empire which had by this time perfected itself. The theory of criminal justice had, in fact, worked round almost to the point from which it started. It had begun in the belief that it was the business of the collective community to avenge its own wrongs by its own hand; and it ended in the doctrine that the chastisement of crimes belonged in an especial manner to the Sovereign as representative and mandatary of his people. The new view differed from the old one chiefly in the air of awfulness and majesty which the guardianship of justice appeared to throw around the person of the Sovereign.
