It is therefore not surprising to find in them the use of torture legalized somewhat after the fashion of the imperial constitutions, and yet with some humane modifications and restrictions. Slaves were liable to torture under accusation, but the accuser had first to make oath that he was actuated by neither fraud nor malice in preferring the charge; and he was further obliged to give security that he would deliver to the owner another slave of equal value if the accused were acquitted. If an innocent slave were crippled in the torture, the accuser was bound to give two of like value to the owner, and the sufferer received his freedom. If the accused died under the torture, the judge who had manifested so little feeling and discretion in permitting it was also fined in a slave of like value, making three enuring to the owner, and careful measures were prescribed to insure that a proper valuation was made. If the accuser was unable to meet the responsibility thus incurred, he was himself forfeited as a slave. Moreover, the owner was always at liberty to save his slave from the torture by proving his innocence otherwise if possible; and if he succeeded, the accuser forfeited to him a slave of equal value, and was obliged to pay all the costs of the proceedings.[1468] Freedmen were even better protected. They could only be tortured for crimes of which the penalties exceeded a certain amount, varying with the nature of the freedom enjoyed by the accused. If no confession were extorted, and the accused were crippled in the torture, the judge and the accuser were both heavily fined for his benefit, and if he died, the fines were paid to his family.[1469] There could have been little torturing of slaves as witnesses, for in general their evidence was not admissible, even under torture, against any freeman, including their masters. The slaves of the royal palace, however, could give testimony as though they were freemen,[1470] and, as in the Roman law, there were certain excepted crimes, such as treason, adultery, homicide, sorcery, and coining, in accusations of which slaves could be tortured against their masters, nor could they be preserved by manumission against this liability.[1471]
