Of the various authorities at our disposal, Bancroft gives the most acceptable characterization of the residencia. He defines it as an examination held, or an account taken, of the official acts of an executive or judicial official within the province of his jurisdiction during the term of his incumbency. This, Bancroft says, was done at the expiration of the term of office or at stated periods, or, in case of malfeasance, at any time. [213] The principle underlying the institution of the residencia was bequeathed to the Spaniards by the Romans, being similar to and probably derived from their law which gave the right of accusation to any Roman citizen against an office-holder. The residencia was conducted by a judicial official, and it combined the features of a general survey of the career of the official under investigation, an auditing of his accounts and a formal trial. Its purpose was to ascertain whether or not the official had faithfully executed his duties and it served to clear him if he were proved honest, giving him a clean certificate of recommendation. If he were found guilty of official misconduct or dishonesty he was apprehended, degraded, and punished, according to his deserts. Professor Bourne has written in regard to the residencia: The residencia ... was an institution peculiar in modern times of the Spanish colonial system. It was designed to provide a method by which officials could be held to strict accountability for all acts during their term of office.... To allow a contest in the courts involving the governor's powers during his term of office would be subversive of his authority. He was then to be kept in bounds by realizing that a day of judgment was impending, when everyone, even the poorest Indian, might in perfect security bring forward his accusation. In the Philippines the residencia for a governor lasted six months and was conducted by his successor and all the charges made were forwarded to Spain.... The Italian traveller Gemelli Careri who visited Manila in 1696 characterizes the governor's residencia as a "dreadful Trial", the strain of which would sometimes "break their hearts." Professor Bourne stated that it was the opinion of De Pons that "the severities of the residencia could be mitigated, and no doubt such was the case in the Philippines. By the end of the eighteenth century the residencia seems to have lost its efficacy." [214]
