For Aulus Caecina (69-72)

In the first place, have they been given rightly, or wrongly? If they were given rightly, that was the law which was decided to be so. If they were wrong, then it cannot be doubtful which are to be blamed, the judges or the lawyers. Besides, if any decision has been given on a disputed point, they are not deciding against the opinion of the lawyers, if they give sentence contrary to the decision of Mucius, any more than they would be deciding in compliance with their authority, if sentence were given according to the precedent of Manilius. Forsooth, Crassus himself did not plead his cause before the centumviri in such a way as to speak against the lawyers; but he urged that the arguments which Scaevola brought forward in his defence were not law; and he not only brought forward good arguments to that point, but he also quoted Quintus Mucius, his father-in-law, and many other most learned men, as precedents.

Therefore in other disputes and trials, when the question at issue is, whether a thing has been done or not, whether what is alleged be true or false; and when false witnesses are sometimes suborned, and false documents foisted in; it is possible that sometimes a virtuous judge may be led into error by a seemingly honourable and probable pretence; or that an opportunity may be given to a dishonest judge, of appearing to be guided by the witnesses, or by the documents produced, though in reality he has knowingly given a wrong decision. For questions of law there is nothing of this sort, O judges: there are no forged documents, no dishonest witnesses; even that overgrown power, which has sway in this state, is dormant with respect to cases of this sort; it has no means of attacking the judge, or of moving a finger.

For this can be said to a judge by some man who is not so scrupulous as he is influential; “Decide, I pray you, that this has been done or planned; give credit to this witness; establish the genuineness of these documents;”— but this cannot be said, “Decide that if a man has a posthumous son born to him, his will is not thereby invalidated; decide that a thing is due which a woman had promised without the sanction of her trustee.” There is no opening for transactions of this sort, nor for any one's power or influence; in fact,—and this gives questions of law a more important and a more holy character,—a judge cannot be corrupted even by a bribe in cases of this sort.
