The jurisdiction of the comitia in criminal cases suffered more extensive curtailment from the standing courts,—quaestiones perpetuae,—the first of which was established in 149 for the trial of Roman officials accused of extortion—repetundae—committed in the provinces or in Italy.[1563] As the object of the prosecutors was in the main the recovery of extorted property, the court was essentially civil, and seemed, therefore, to the Romans no infringement of popular rights; yet even before Sulla the principle began to apply to distinctly criminal cases.[1564] Notwithstanding this development several accusations were brought before the centuriate assembly in the period between the Gracchi and Sulla.[1565] The latter increased the number of quaestiones to seven and brought all crimes within their cognizance. The questorian jurisdiction in cases of murder had already passed to the quaestio inter sicarios, established between 149 and 141;[1566] and now Sulla transferred cases of perduellio from the jurisdiction of the tribunes to the quaestio maiestatis.[1567] Although restored to the tribunes in 70, it was for the remainder of the republican period exercised by them on special occasions only, for the quaestio maiestatis still existed. With the establishment of the principate the jurisdiction of the people finally vanished.[1568] The revolutionary character of the period after Sulla is illustrated by the case of perduellio against C. Rabirius[1569] brought in 63 by a tribune of the plebs, T. Atius Labienus. Rabirius was charged with complicity in the murder of L. Appuleius Saturninus, the famous tribune of the year 100. Labienus proposed and carried a plebiscite requiring the praetor to appoint duumviri for the trial, whereas it was generally held at the time that these officials should have been elected by the people. It was also enacted, in violation of the Porcian and Sempronian laws, that in case of conviction the accused should be crucified on the Campus Martius. C. and L. Caesar, appointed duumviri, brought the case before the comitia centuriata, which were prevented from giving their verdict by the removal of the flag from Janiculum.[1570] The object of the trial was not to punish the guilty, but to discredit the senate, to which the accused belonged.[1571] The decline of the idea of popular sovereignty is further indicated by the agrarian rogation of the tribune P. Servilius Rullus, 63, an article of which, in violation of the lex Valeria Horatia de provocatione, ordered the appointment of decemviri agris adsignandis without appeal.[1572]
