As a whole, the Partidas were too elaborate and too much in advance of the wants of the age to be immediately successful as a work of legislation, and they were not confirmed by the Córtes until 1348. In the Ordenamiento de Alcalà of Alfonso XI., issued in-that year, they are referred to as supplying all omissions in subsequent codes.[1494] It is probable that in his system of torture Alfonso the Wise merely regulated and put into shape the customs prevalent in his territories, for the changes in it which occurred during the succeeding three or four centuries are merely such as can be readily explained by the increasing influence of the revived Roman jurisprudence, and the introduction of the doctrines of the Inquisition with respect to criminal procedures. In the final shape which the administration of torture assumed in Castile, as described by Villadiego, an eminent legist writing about the year 1600, it was only employed when the proof was strong, and yet not sufficient for conviction. No allusion is made to the torture of witnesses, and Villadiego condemns the cruelty of some judges who divide the torture into three days in order to render it more effective, since, after a certain prolongation of torment, the limbs begin to lose their sensibility, which is recovered after an interval, and on the second and third days they are more sensitive than at first. This he pronounces rather a repetition than a continuation of torture, and repetition was illegal unless rendered necessary by the introduction of new testimony.[1495] As in the thirteenth century, nobles, doctors of law, pregnant women, and children under fourteen were not liable, except in cases of high treason and some other heinous offences. The clergy also were now exempted, unless previously condemned as infamous, and advocates engaged in pleading enjoyed a similar privilege. With the growth of the Inquisition, however, heresy had now advanced to the dignity of a crime which extinguished all prerogatives, for it was held to be a far more serious offence to be false to Divine than to human majesty.[1496] The Partidas allow torture in the investigation of comparatively trivial offences, but Villadiego states that it should be employed only in the case of serious crimes, entailing bodily punishment more severe than the torture itself, and torture was worse than the loss of the hands. Thus, when only banishment, fines, or imprisonment were involved, it could not be used. The penalties incurred by judges for its excessive or improper application were almost identical with those prescribed by Alfonso, and the limitation that it should not be allowed to endanger life or limb was only to be exceeded in the case of treason, when the utmost severity was permissible.[1497] In 1489 Ferdinand and Isabella had directed that no criminal case should be heard by less than three alcaldes or judges sitting together, and torture could not be employed
