Preparation for Attacks on Caesar
This very demand became the battle-field of the diplomatic war which now began. If Caesar were compelled either to resign his office of governor before the last day of December 705, or to postpone the assumption of the magistracy in the capital beyond the 1st January 706, so that he should remain for a time between the governorship and the consulate without office, and consequently liable to criminal impeachment--which according to Roman law was only allowable against one who was not in office-- the public had good reason to prophesy for him in this case the fate of Milo, because Cato had for long been ready to impeach him and Pompeius was a more than doubtful protector.
Attempt to Keep Caesar Out of the Consulship
Now, to attain that object, Caesar's opponents had a very simple means. According to the existing ordinance as to elections, every candidate for the consulship was obliged to announce himself personally to the presiding magistrate, and to cause his name to be inscribed on the official list of candidates before the election, that is half a year before entering on office. It had probably been regarded in the conferences at Luca as a matter of course that Caesar would be released from this obligation, which was purely formal and was very often dispensed with; but the decree to that effect had not yet been issued, and, as Pompeius was now in possession of the decretive machinery, Caesar depended in this respect on the good will of his rival.
