Much contradictory legislation appears in the laws of the Indies relative to the method of taking residencias; this due to the reforms made from time to time. These laws were formulated for a growing empire. A chronological review of them will show that the residencia was at first more or less of an experiment. Indeed, all the colonial institutions were in the early periods passing through an experimental stage and these seemingly contradictory laws were promulgated or repealed, according to their success or failure when put into effect. Whenever, therefore, two laws appear to be in conflict, the one of later date will be found to supersede and repeal the earlier one. [231] In illustration of this characteristic of the laws of the Indies we may note the following example: The cédula of December 4, 1630, ordered that the residencia of the governor should be taken by his successor. This law was seldom, if ever, observed. Owing to the distance from Spain and New Spain, and the consequent length of time consumed in voyages, to the unhealthful climate, and to the dangerous military campaigns in which the governors were compelled to engage, death frequently intervened before the successor of a governor arrived. These conditions (which were characteristic of all of Spain's colonies) did not prevent the residencia from being taken, but caused the law to be modified by the cédula of December 28, 1667, according to which judges for the residencias of viceroys and presidents-governor and captains-general were to be designated by the court. The period of four months, which had been authorized for the taking of residencias by the cédula of August 30, 1582, was extended to six months. [232] A change was necessary, the new law declared, in order to put a stop to the incessant strife, and the malice which had been shown by viceroys, governors, and ministers in the taking of residencias. The king determined that henceforth the judge of residencias should be designated by the court. The magistrate usually named was the decano. After 1776 the regent almost invariably conducted these investigations. The important reform of August 24, 1799, ordered that judges of residencia for governors, viceroys, presidents, governors-intendant, corregidor-intendants, and presidents of the Council of the Indies should be appointed by the king. [233] The first residencia to be conducted in the Philippines in accordance with the new law of November 28, 1667, was that of Governor Salcedo, in 1670. This governor had been removed by the commissary of the Inquisition on October 10, 1668, and Francisco Coloma, the decano, was ordered to take his residencia. [234] Coloma's intervention in the matter was protested by the audiencia in a letter to the Council of the Indies, dated April 7, 1670, on the grounds that the senior oidor was also the asesor and possible successor of the governor, and for that reason he was disqualified from taking the latter's residencia.
