A variety of laws exist in the Recopilación prescribing the duties and conduct of the audiencia when it had charge of governmental affairs, and defining the relationship which should exist between the oidores under such conditions. The magistrates were ordered to proceed harmoniously and moderately both in the execution of governmental affairs and in the administration of justice, not erring either on the side of excessive severity, or of undue moderation. They were to devote special attention to the increase and care of the royal revenue during these times. [601] The right to grant encomiendas, essentially the function of the governing authority, was conceded to the audiencia when it acted in the capacity of governor. All such concessions ultimately had to be confirmed by the king. On these occasions, also, the audiencia filled vacancies and made appointments. However, the oidores were warned against discharging officials and vacating offices in order to fill them with their dependents and friends. [602] All appointments made by the audiencia were to become void after the arrival of a regular governor, unless they had subsequently received the royal confirmation. When a vacancy arose, it was the duty of the senior magistrate to propose a candidate, but the actual filling of the place was to be effected by the acuerdo vote of the entire audiencia. [603] The laws provided that the audiencia, as a body, should exercise two distinct types or classes of powers when in charge of the government. These were designated as governmental and military. The exercise of these functions was assigned respectively to the audiencia as a body, and to the senior magistrate, individually. While an effort was made to insure the fair and equal participation of all in government in case of a vacancy, the senior magistrate assumed the position and honors of the executive, though not granted all the governor's powers. [604] In the functions and duties of administration all the magistrates were to participate. As noted above, each was to have a share in the exercise of the appointing power, the administration of colonial finances, participation in the acuerdo, and in every other function except defense, which was entrusted to the senior oidor. In this capacity, the oidor was always the most prominent figure in the government. Among those who distinguished themselves through the exercise of this power were Rojas, Morga, Alcaraz, Bónifaz, Coloma, Montemayor, and above all, Anda. Although these men were assisted and supported by their colleagues of the audiencia, and the parts played by the latter were not without importance, the periods of rule of the audiencia are always identified with the names of the senior oidores, while those of the ordinary magistrates are forgotten.
