The law, which has been cited already, providing that the administration of the Indies should be patterned in all ways after the governments of Castile and León, shows very clearly the natural influence of the early history and institutions of Spain. The audiencias established in the colonies were at first similar in jurisdiction and organization to those of Spain, which country had already succeeded in governing provinces that were, in effect, almost as isolated and as far from actual contact with the court as were the Indies. The audiencia of Spain had proved of immense value as an agency of direct control. It had been found satisfactory under conditions very similar to those in the Indies, which were not regarded as foreign possessions, but as integral parts of Castile, being the property of the monarchs of that kingdom, and under their personal direction. Before proceeding with a description of the growth of the audiencia system, it is desirable, first, to note the establishment in Spain of two organs for the administration of colonial affairs. These may be examined here conveniently, because their creation antedated the institution of the audiencia in the colonies. The first, chronologically, as well as in importance, was the Casa de Contratación, which was created January 10, 1503. [9] This essentially commercial body was intended at first to supervise the import and export trade of Spain with the colonies, and to arrange for the sale and distribution of imported articles, concessions of cargo to individuals, the lading and discharging of cargo, and the collection of duties. The functions of this body were soon amplified to the extent that it was given jurisdiction over emigration to the colonies. In 1509 it was granted further authority over certain criminal cases relating to trade, and in 1510, letrados were added to the tribunal of the Casa for the better determination of legal affairs. As established in 1503, the Casa de Contratación consisted of a treasurer, auditor (comptroller), and factor. [10] That the institution flourished and increased in importance may be deduced from the reform of Philip II, on September 25, 1583, whereby the above mentioned officials were retained and a royal audiencia was created within the Casa. This was composed of three jueces letrados and a fiscal, besides the numerous subordinate officials who usually accompanied the judicial tribunal. [11] Though at first it exercised some of the functions which belonged later to the Council of the Indies, it came subsequently to be subordinate to that body. [12] It was transferred to Cádiz in 1717, and was suppressed by the royal decree of June 18, 1790. [13] its remaining attributions being assumed by the Consulado of Seville. [14]
