Against Philippides (12)

And secondly, compare the case of false witness. If people have been twice convicted of this, you have allowed them to refrain from giving evidence a third time, even of events at which they have themselves been present, so that, if anyone is disfranchised, responsibility shall rest, not on the people, but on the man himself, for continuing to bear false witness. Similarly men convicted of illegal proposals need not bring forward proposals in future. If they do they are clearly actuated by some private motive. So that people of this type deserve punishment, not pity.
