1. The law by which the Judices were to be taken only from the Equites, and not from the Senators, as had been the custom hitherto. This was a very important enactment, and needs a little explanation. All offenses against the state were originally tried in the Popular Assembly; but when special enactments were passed for the trial of particular offenses, the practice was introduced of forming a body of Judices for the trial of these offenses. This was first done upon the passing of the Calpurnian Law (B.C., 149) for the punishment of provincial magistrates for extortion in their government (_De Repetendis_). Such offenses had to be tried before the Praetor and a jury of Senators; but as these very Senators either had been or hoped to be provincial magistrates, they were not disposed to visit with severity offenses of which they themselves either had been or were likely to be guilty. By depriving the Senators of this judicial power, and by transferring it to the Equites, Gracchus also made the latter a political order in the state apart from their military character. The name of Equites was now applied to all persons who were qualified by their fortune to act as Judices, whether they served in the army or not. From this time is dated the creation of an _Ordo Equestris_, whose interests were frequently opposed to those of the Senate, and who therefore served as a check upon the latter. 2. Another law was directed against the arbitrary proceedings of the Senate in the distribution of the provinces. Hitherto the Senate had assigned the provinces to the Consuls after their election, and thus had had it in their power to grant wealthy governments to their partisans, or unprofitable ones to those opposed to them. It was now enacted that, before the election of the Consuls, the Senate should determine the two provinces which the Consuls should have; and that they should, immediately after election, settle between themselves, by lot or otherwise, which province each should take.
