At the same time was ordered a reduction in the duties and the permission of importing foreign goods, though they always had to be carried in Spanish boats. These duties were henceforth three per cent. on Spanish products, and seven per cent. on foreign products. When the value of the goods was greater than their bulk, a duty was levied, called estranjeria (foreign custom). As a result of this reform, the revenues of Cuba which in 1764 had amounted to not more than three hundred and sixteen thousand pesos, rose in the year 1777 to one million twenty seven thousand two hundred and thirteen pesos. Contraband which had been one of the worst evils that the Cuban authorities had to contend with for two centuries, visibly declined and was soon limited to articles of luxury. At the same time there was also ordered by royal decree the unification of the coinage, and the macuquino, a coin with the milled edges cut off, was replaced by one of silver with a corded edge. All these reforms were received by the people with unbounded enthusiasm. In all parts of the island the inhabitants spontaneously gave vent to their joy in brilliant festivals and in a display of oratory, which acclaimed the beginning of the new era for Cuba.
Like Buccarelli, Governor Navarro was much concerned with the legal malpractice that had long existed in the courts. The bar was composed of many men who with insidious cunning stirred up and prolonged innumerable lawsuits. Their machinations not only violated the sense of justice, but directly disgraced their profession and the judicial administration of the island. So many families had been ruined by such legal procedures, that Governor Navarro was determined to check the operations of these sharks. He ordered that no one but a duly appointed notary should be permitted to draft legal documents and perform judicial acts and he reduced the number of these men to thirty-four for the whole island. He also appointed an appraiser to adjust the costs of legal proceedings and ordered that lawyers who had been convicted of malpractice should be deprived of the right to plead. The Audiencia of Santo Domingo protested against some of these decisions of Navarro, but he succeeded in convincing the court of the justice of his acts.
