On this account Octavius at first tried to hold himself aloof, out of regard for Tiberius; but he was forced from his position, as it were, by the prayers and supplications of many influential men, so that he set himself in opposition to Tiberius and staved off the passage of the law. Now, the decisive power is in the hands of any tribune who interposes his veto; for the wishes of the majority avail nothing if one tribune is in opposition.
Incensed at this procedure, Tiberius withdrew his considerate law, and introduced this time one which was more agreeable to the multitude and more severe against the wrongdoers, since it simply ordered them to vacate without compensation the land which they had acquired in violation of the earlier laws.
