From: The History of Rome, by Theodor Mommsen
Translated with the sanction of the author by William Purdie Dickson
The jury-commissions were left in existence, but limits were put to the right of counter-plea, and--what was perhaps still more important--the liberty of speech in the courts was done away; for both the number of the advocates and the time of speaking apportioned to each were restricted by fixing a maximum, and the bad habit which had prevailed of adducing, in addition to the witnesses as to facts, witnesses to character or -laudatores-, as they were called, in favour of the accused was prohibited. The obsequious senate further decreed on the suggestion of Pompeius that the country had been placed in peril by the quarrel on the Appian Way; accordingly a special commission was appointed by an exceptional law for all crimes connected with it, the members of which were directly nominated by Pompeius. An attempt was also made to give once more a serious importance to the office of the censors, and by that agency to purge the deeply disordered burgess-body of the worst rabble.
All these measures were adopted under the pressure of the sword. In consequence of the declaration of the senate that the country was in danger, Pompeius called the men capable of service throughout Italy to arms and made them swear allegiance for all contingencies; an adequate and trustworthy corps was temporarily stationed at the Capitol; at every stirring of opposition Pompeius threatened armed intervention, and during the proceedings at the trial respecting the murder of Clodius stationed contrary to all precedent, a guard over the place of trial itself.
