fictitious averments into their writs which enabled them to trespass on each other's peculiar province. Like the Quaestiones, the Courts of Queen's Bench, Common Pleas, and Exchequer were all theoretical emanations from a higher authority, and each entertained a special class of cases supposed to be committed to it by the fountain of its jurisdiction; but then the Roman Quaestiones were many more than three in number, and it was infinitely less easy to discriminate the acts which fell under the cognisance of each Quaestio, than to distinguish between the provinces of the three Courts in Westminster Hall. The difficulty of drawing exact lines between the spheres of the different Quaestiones made the multiplicity of Roman tribunals something more than a mere inconvenience; for we read with astonishment that when it was not immediately clear under what general description a man's alleged offences ranged themselves, he might be indicted at once or successively before several different Commissions, on the chance of some one of them declaring itself competent to convict him; and, although conviction by one Quaestio ousted the jurisdiction of the rest, acquittal by one of them could not be pleaded to an accusation before another. This was directly contrary to the rule of the Roman civil law; and we may be sure that a people so sensitive as the Romans to anomalies (or, as their significant phrase was, to _inelegancies_) in jurisprudence, would not long have tolerated it, had not the melancholy history of the Quaestiones caused them to be regarded much more as temporary weapons in the hands of factions than as permanent institutions for the correction of crime. The Emperors soon abolished this multiplicity and conflict of jurisdiction; but it is remarkable that they did not remove another singularity of the criminal law which stands in close connection with the number of the Courts. The classifications of crimes which are contained even in the Corpus Juris of Justinian are remarkably capricious. Each Quaestio had, in fact, confined itself to the crimes committed to its cognisance by its charter. These crimes, however, were only classed together in the original statute because they happened to call simultaneously for castigation at the moment of passing it. They had not therefore anything necessarily in common; but the fact of their constituting the particular subject-matter of trials before a particular Quaestio impressed itself naturally on the public attention, and so inveterate did the association become between the offences mentioned in the same statute that, even when formal attempts were made by Sylla and by the Emperor Augustus to consolidate the Roman criminal law, the legislator preserved the old grouping. The Statutes of Sylla and Augustus were the foundation of the penal jurisprudence of the Empire, and nothing can be more extraordinary than some of the classifications which they bequeathed to it.
