Unknown Pleader Against Evergus and Mnesibulus, About False Testimony (1-2)

It is in my opinion, men of the jury, an admirable provision of the laws that they allow another chance after a trial by means of proceedings for false testimony, in order that, if anyone by bringing forward witnesses testifying to what is false or by citing challenges which were never tendered or depositions made contrary to law, has deceived the jury, he may gain nothing by it, but the one who has been wronged may impeach the testimony, and come into your court and show that the witnesses have given false testimony regarding the matter at issue, and thus exact the penalty from them and hold the one who brought them forward liable to an action for subornation of perjury.

And for this reason they have made the fine less for the plaintiff, if he lose his case, in order that those who have been wronged may not by the fine be deterred from prosecuting witnesses for false testimony, while they have imposed a heavy penalty upon the defendant, if he be convicted and be thought by you to have given false testimony.
