As we approach firmer historical ground, we hear of three accusations of unnatural lust alleged to have been brought by the tribunes of the plebs before the same comitia: (1) that against L. Papirius, 326,[1495] (2) that against L. or M. Laetorius Mergus, a military tribune, quod cornicularium suum stupri causa appellasset,[1496] (3) the case mentioned by Pliny and others against a person of unknown name, which probably belongs to this period.[1497] The second case seems to be a trial of official accountability, which fell within tribunician jurisdiction according to the usage of historical time; the others are too little known to be legally formulated. In this period falls the attempted prosecution of Appius Claudius Caecus, 310, on the ground that he had not laid down the censorship at the end of the limit of eighteen months.[1498] The accusing tribune ordered him to be seized and imprisoned, but three colleagues interceded.[1499] About the same time M. Atilius Calatinus was unsuccessfully prosecuted on a charge of having betrayed Sora,[1500] probably in connection with the defection of that town to the Samnites in 315.[1501] In reviewing the cases said to have been brought by tribunes before the comitia centuriata it is surprising to find the period from the institution of the office to the trial of Q. Fabius, 390, swarming with such prosecutions, whereas for the century intervening between that date and the Hortensian legislation comparatively few cases are recorded and those of little significance.[1502] These circumstances tend to prove that the cases assigned to the earlier and less known period either belong mostly to the jurisdiction of the duumviri or of the quaestors rather than of the tribunes, or are in great part mythical, and that the tribunes, therefore, exercised no extensive capital jurisdiction before the enactment of the Hortensian law.[1503] We are led thence to the conclusion that either by an article of the statute of Hortensius or at least as a recognized consequence of the high place in the government assured the tribunes by it, the jurisdiction of these magistrates in political cases was freed from every restraint. At this time they succeeded wholly to the place of the duumviri. The cases of which the tribunes had cognizance were thereafter exclusively political, whereas the questorian jurisdiction was confined to murder and other common crimes. This distinction was not a limitation upon the power of the tribunes, who if they chose might have superseded the quaestors as easily as they had superseded the duumviri. It was rather a division of functions adopted by the tribunes themselves in view of their own political character and on the basis of the relative dignity of the two offices. The chief judicial function of the tribunes, accordingly, was to hold officials responsible for their administration, though occasionally they called private persons to account for their conduct as citizens.
