On the Agrarian Law (1.25-1.26)

But when I have displayed the wickedness of your counsels, the dishonesty of your law, and the treachery which is planned by those popular tribunes of the people against the Roman people; then, I suppose, I shall have reason to fear that I shall not be allowed to appear in the assembly, for the purpose of opposing you; especially when I have determined and resolved so to conduct myself in my consulship, (and the duties of the consulship cannot be discharged with dignity and freedom, in any other manner,) as neither to desire any province, nor honour, nor dignity nor advantage nor anything whatever which can have any hindrance thrown in its way by any tribune of the people.

The consul states, in full senate, on the calends of January, that if the present condition of the republic continues, and if no new event arises, on account of which he cannot with honour avoid it, he will not go to any province. By that means I shall be able, O conscript fathers, so to behave myself in this magistracy, as to be able to restrain any tribune of the people who is hostile to the republic,—to despise any one who is hostile to myself.
