A slave is not to be believed at all if he should try to prove any one else guilty of crime, or if he should endeavor to implicate his master in any offence. And even if he should be subjected to torture, and should confess what he has done, still he must not be believed; an exception, however, being made in the case of such slaves as have been transferred to the royal service, and are deservedly honored with the offices of the palace; that is to say, the chiefs of the grooms, of the fowlers, of the silversmiths, and of the cooks; or any besides these who are superior to them in rank or position. Moreover, to any slaves who are well and favorably known to the king, and who have never been guilty of depravity or crime, permission is granted by the law to testify, as well as to persons who are freeborn. But it must not be thought that other slaves in the royal service can be called as witnesses, for no credit shall attach to any of them, unless the king should especially authorize their testimony to be taken.[12] =FLAVIUS CHINTASVINTUS, KING.= =V. A Witness shall not give His Testimony in Writing, but Orally; and How Testimony should be Given.= Witnesses shall not give testimony by letter, but present, in person, they shall be required to tell the truth, as far as lies in their knowledge. Nor shall they testify concerning foreign matters, but only concerning those which they know to have taken place under their own eyes. But if the witnesses, or their relatives, or friends, should either be oppressed with age or infirmity, or resident in a foreign or distant province, and should think that their testimony should be taken, and if all those concerned in the case are not residents of the same province, they shall assemble in that province, where he who is the highest in rank among the parties lives, and, either in the presence of the judge of the district, or of those whom he shall select, and those interested having been duly summoned, shall give their evidence under oath. Any other proceeding relating to such matters shall be void and of no effect in law.[13] =FLAVIUS CHINTASVINTUS, KING.= =VI. Concerning Those who give False Testimony.=
