Still, a tribunal, whose undefined powers and secrecy of action fitted it so perfectly for use as a political agent, could scarce exist for centuries without occasionally being called upon, and the only legitimate source of surprise is that it was so rarely employed and that the objects for its intervention were usually so trivial. Ferdinand occasionally found it a convenience in settling questions outside of its regular functions, as when Marco Pellegrin appealed to him in a dispute with the authorities of his city and Ferdinand wrote, August 31, 1501, to the inquisitor of the place, charging him to examine the question and do justice, for which he gave him full royal power. So when, in 1500, complaints reached him from Valencia of injustice in the assessments for a servicio, he ordered the papers to be submitted to the inquisitor who was to report to him, and, in 1501, he called for a report from the inquisitor of Lérida as to the necessity of certain repairs to the castle.[545] When, in 1498, he was endeavoring to carry out in Aragon the reform of the Conventual Franciscans, which Ximenes had undertaken in Castile, and they had obtained papal briefs restraining him, he applied to the pope to revoke the letters and meanwhile obtained others from the nuncio, which he transmitted to the tribunal of Saragossa with instructions to act promptly. The inquisitors carried on the reform much to his satisfaction and, when the frailes got the public authorities to protect them, he instructed the inquisitors to represent that they were acting under apostolic authority, that there was no violation of the liberties of the kingdom, that they were salaried by the king, not only for the Inquisition but for whatever duties he might assign to them; they were therefore public officers and, if the Saragossa authorities should endeavor to create scandal, they would be duly punished. This distinction between inquisitorial and non-inquisitorial functions, however did not prevent him, when occasion required, from enforcing outside operations with inquisitorial authority. In 1502, when prosecuting, in the same way, the Franciscan reform in Sardinia and the Bishop of Ocaña, in virtue of a surreptitious papal letter, released from the castle of Fasar the Franciscan vicar, Ferdinand wrote with much indignation to him and to the governor of Cabo de Lugador; it was great audacity to intervene, in a matter concerning the Inquisition, without consulting him or the inquisitor-general; the prisoner must be recaptured forthwith and be held until the inquisitor and _reformador apostolico comes_.[546]
