The Licinian laws had the unexpected effect of adding two new magistracies to the state. These were known as the Praetorship and the Curule Aedileship. The institution of the former office was a constitutional change of the first magnitude, being nothing less than the addition of a third colleague to the consuls. It is represented as having been a part of the compromise between the orders, the Plebeians allowing a third purely patrician magistracy to be created in exchange for the confiscated consulship.[459] But, even if we assume that the praetorship was originally confined to the _patres_—a statement which has with some reason been doubted[460]—it was necessity rather than ambition which directed the creation of the office. The impossibility of the consul’s paying adequate attention to duties of jurisdiction had been one of the motives which led to the establishment of the consular tribunate. Now that the consulship was permanently restored, provision had to be made for the permanent severance of civil jurisdiction from that office. As jurisdiction implied the _imperium_, and all the possessors of this regal prerogative were necessarily colleagues, the praetor was a colleague of the consuls. He was created, as the phrase ran, “under the same auspices,”[461] and therefore by the same assembly and under the same formalities of election. He bore the early title of the consuls, which, in spite of its inappropriateness to his usual peaceful duties, came to cling to him exclusively. But, though he was needed chiefly for purposes of jurisdiction, one branch of the _imperium_ could not be singled out to the exclusion of the others. The praetor possesses all the aspects of the supreme power, the capacity for command in war, for initiating legislation, for summoning and transacting business with the Senate. How these powers were harmonised with, and subordinated to, the similar powers of the consuls, will be described elsewhere. The main business of the original praetor did not clash with that of his colleagues, for, though in theory perhaps the consul never did lose his control of civil jurisdiction,[462] practice decided against his interference with it, and the praetor was for more than 120 years (366-242) the sole civil magistrate of Rome. At the close of this period a second praetor was appointed, whose duty it was to decide cases between foreigners (_peregrini_) and between Roman citizens and foreigners—an addition rendered necessary by the growth of Rome’s territory and business, and which has no further political significance. The praetorship, if it ever was a patrician preserve, did not long remain such. Thirty years after its institution (337 B.C.) a Plebeian, Q. Publilius Philo, successfully contested the post. The objections of the presiding magistrate, whether based on law or custom, were overruled and Plebeians declared eligible for the office.[463]
