From: The History of Rome, by Theodor Mommsen
Translated with the sanction of the author by William Purdie Dickson
Encouraged by this victory of their bands over those of their antagonist, the senate suspended the tribune Nepos as well as the praetor Caesar, who had vigorously supported him in the bringing in of the law, from their offices; their deposition, which was proposed in the senate, was prevented by Cato, more, doubtless, because it was unconstitutional than because it was injudicious. Caesar did not regard the decree, and continued his official functions till the senate used violence against him.
As soon as this was known, the multitude appeared before his house and placed itself at his disposal; it was to depend solely on him whether the struggle in the streets should begin, or whether at least the proposals made by Metellus should now be resumed and the military command in Italy desired by Pompeius should be procured for him; but this was not in Caesar's interest, and so he induced the crowds to disperse, whereupon the senate recalled the penalty decreed against him. Nepos himself had, immediately after his suspension, left the city and embarked for Asia, in order to report to Pompeius the result of his mission.
