Where any person authorizes another to conduct a case for him, and dies before it is heard, said authority shall determine; and if he who received it should be surprised by death before the cause is heard, then also the order addressed to him before his death shall have no validity. But if the cause has been heard and energetically prosecuted through his diligence, and yet, for some reason or other, it was not entirely concluded, or some payment should remain to be made before final settlement; and if the case has been prosecuted as far as he who was commissioned to conduct it should have carried it; then, his heirs shall be entitled to receive from the constituent whatever compensation their ancestor would have been entitled to. =FLAVIUS CHINTASVINTUS, KING.= =IX. What Persons those in Power, and those that are Poor, may appoint to Conduct their Cases.= It shall not be lawful for any one who selects an attorney to conduct his case, under any circumstances, to appoint a person who is more powerful than himself, so that the capacity to oppress, or terrify, may be greater than his own. For if a powerful person should be involved in a lawsuit with one who is poor, and is unwilling to conduct it himself, he cannot appoint any one else to carry it on but one of equal standing with, or perhaps inferior to, the other party. But, on the other hand, if a poor man chooses, he may select as his attorney any one of equal rank and power with his adversary. =FLAVIUS CHINTASVINTUS, KING.= =X. Those who have Charge of the Royal Treasury, when a Suit is brought for its Benefit, have authority to appoint whom they wish to represent them.= Nothing should be done rashly in matters relating to the royal treasury. And whenever it appears advisable to proceed against any one on behalf of the treasury, he who is charged with that duty shall have the right to conduct the case before either the governor of the city, or the judge. If, however, he should happen to be absent from the place where the business is to be transacted, or should be prevented by any accident, or even should be unwilling to appear in his own person, he shall have the unquestionable right to appoint any one he chooses, to bring an action in which the public interests are involved.[10] TITLE IV. CONCERNING WITNESSES AND EVIDENCE. =I.= _Concerning Persons who are not Permitted to Testify._ =II.= _Witnesses shall not Testify except under Oath; Where both parties offer Witnesses which should be Believed; and Where a Witness Testifies Falsely._ =III.= _Where a Witness Testifies Orally, and Written Evidence Contradicts Him._ =IV.= _A Slave shall not be Believed unless he Belongs to the Crown; and When Royal Slaves shall be Believed._ =V.= _A Witness shall not give His Testimony in Writing, but Orally, and How Testimony should be Given._
