But the regard for the property of the State was unfortunately not extended to the property of its clients. Even before the provinces had yielded a prey rendered easy by distance and irresponsibility, Italian cities had been forced to complain of the violence and rapacity of Roman commanders quartered in their neighbourhood,[118] and the passive silence with which the Praenestines bore the immoderate requisitions of a consul, was a fatal guarantee of impunity which threatened to alter for ever the relations of these free allies to the protecting power.[119] But provincial commands offered greater temptations and a far more favourable field for capricious tyranny; for here the exactions of the governor were neither repudiated by an oath of office nor at first even forbidden by the sanctions of a law. Requisitions could be made to meet the needs of the moment, and these needs were naturally interpreted to suit the cravings and the tastes of the governor of the moment.[120] Cato not only cut down the expenses that had been arbitrarily imposed on the unhappy natives of Sardinia,[121] but seems to have been the author of a definite law which fixed a limit to such requisitions in the future.[122] But it was easier to frame an ordinance than to guarantee its observation, and, at a time when the surrounding world was seething with war, the regulations made for a peaceful province could not touch the actions of a victorious commander who was following up the results of conquest. Complaints began to pour in on every hand--from the Ambraciots of Greece, the Cenomani of Gaul[123] --and the senate did its best, either by its own cognisance or by the creation of a commission of investigation, to meet the claims of the dependent peoples. A kind of rude justice was the result, but it was much too rude to meet an evil which was soon seen to be developing into a trade of systematic oppression. A novel step was taken when in 171 delegates from the two Spains appeared in the Curia to complain of the avarice and insolence of their Roman governors. A praetor was commissioned to choose from the senatorial order five of such judges as were wont to be selected for the settlement of international disputes (_recuperatores_), to sit in judgment on each of the indicted governors,[124] and the germ of a regular court for what had now become a regular offence was thus developed. The further and more shameful confession, that the court should be permanent and interpret a definite statute, was soon made, and the Calpurnian law of 149[125]was the first of that long series of enactments for extortion which mark the futility of corrective measures in the face of a weak system of legal, and a still weaker system of moral, control. Trials for extortion soon became the plaything of politics, the favourite arena for the exercise of the energies of a young and rising politician, the favourite weapon with which old family feuds might be at once revenged and perpetuated. They
