As soon as there came to be plebeian senators (about 400), the patricians reserved to themselves the right to decide on the legality of legislative and elective acts of the people under patrician presidency—a right designated by the phrase patrum auctoritas, which signified originally the authorization of the senators, thereafter of the patrician senators. Till 339 the patres were at liberty to give or withhold the auctoritas; but in that year an article of the Publilian law required them to grant it to legislative acts of the centuries before the voting began and while the issue was still in doubt, reducing it in this way to a mere formality.[1413] The effect was to free centuriate legislation from the constitutional control hitherto exercised by patrician senators.[1414] Henceforth the resolutions of this assembly could be declared illegal by no less than a majority of the entire senate. The Publilian statute, accordingly, deprived the patricians of an important power, whereas the senate as a whole continued through its consulta to exercise an increasing influence over the comitia centuriata. Polybius rightly ascribes to the consuls, therefore, the function of bringing the resolutions of the senate before the assembly. It could not have been the intention of Publilius Philo to energize the comitia centuriata by this provision; for another article of the same statute, confirming the validity of the tribunician assembly of tribes, as then actually constituted exclusively of plebeians, paved the way for the Hortensian law, which by making the acts of the tribunician assembly in every respect equal to those of the centuries, deprived the latter of their great importance as a factor in constitutional progress. From the time of Hortensius to the time of Sulla no constitutional statute is known to have been enacted by the centuriate assembly; though our sources do not give us clear information on the point, it is highly probable that the consuls and dictators of this period preferred to bring their measures however important before the tribes.[1415] In Sulla’s time the lex Valeria, 82,[1416] clothing him with his extraordinary dictatorship rei publicae constituendae, must have been passed by the centuries, which alone in addition to the politically obsolete comitia curiata could be summoned by an interrex, as was the author of the law. This act, Lange remarks, cannot well be considered a revival of the legislative power of the centuries, as it was not only passed through intimidation and under a magistrate who had no constitutional right to initiate legislation, but it also created a legalized tyranny destructive of popular freedom.[1417] In the words of Cicero it was the most iniquitous of all laws and most unlike a law.[1418] Only one of Sulla’s statutes, the lex de civitate Volaterranis adimenda, 81, which, depriving the Volaterrani of their civitas cum suffragio, placed them in the condition of the Latins
