The twelve district courts each have a judge of first instance and a judge of instruction, elected by the Senate for terms of four years. The judge of instruction is not, strictly speaking, a part of the court, his duty being to investigate the more serious criminal offenses, commit the offenders for the action of the court and report the result of his investigation to the prosecuting attorney. The courts of first instance have original jurisdiction in all criminal matters except the minor police offenses and in all civil matters except those expressly assigned to the justices of the peace. They hear appeals from the justices of the peace in civil and criminal cases. The local justices of the peace are called "alcaldes." The alcalde, in Spanish times, was an officer exercising both administrative and judicial functions, the name being derived from the Arabic "al cadi," the judge, and whereas in Spain and most of the former Spanish colonies the alcalde has now only administrative duties and his office is equivalent to that of mayor, in Santo Domingo he now exercises solely judicial authority. (The office of "alcalde pedaneo," which may be roughly translated as deputy mayor, exists in Santo Domingo, however, this title being given to the municipal executive's agent in each section.) The alcalde's jurisdiction comprises the smaller police offenses and, in civil cases, matters involving less than $100, as well as certain cases, such as suits between innkeepers and guests, where the limit of his authority is raised to $300, and other cases, such as ejectment suits, where his jurisdiction attaches on account of the subject-matter. The alcaldes are appointed by the president of the Republic. In general the system works smoothly. The alcaldes are often ignorant men, but even in the United States the country magistrates are not always founts of wisdom. The judges of first instance and district attorneys are almost without exception respected in the community, and the present judges of the supreme court and of the courts of appeals enjoy a good reputation. Not infrequently political considerations have given rise to poor appointments, such as occurred in Barahona some years ago when the judge-elect telegraphed an indignant protest to the capital to the effect that he was unacquainted even with the rudiments of the law. The administration had not taken the trouble to ascertain whether he was a lawyer, but knowing he sought a position, had given him the first one at hand. This was rather an oversight, as the law requires such appointees to be members of the bar. On another occasion the legal requisite was filled by first declaring the aspirant a lawyer and then designating him for the post. These cases are exceptions, however. The integrity of the judges is not often questioned, but the alcaldes do not enjoy so good a reputation.
