had already conducted legal work while defending the engineer Ricardo Owen, accused of disobedience, and also his friend and classmate Luis Uribe, accused of disobedience and contempt to his superiors. He succeeded the first time, but he was not so successful with the defence of his friend, who was condemned to six months of jail by six votes. The amnesty of the President saved Uribe and his naval career from that fate. Jurist Prat practised his recently adopted profession for a very short time. He primarily devoted himself to resolving the legal problems of the Chacón and Carvajal families, as well as naval-related problems. He aspired to be a Navy auditor, but he was only sworn as "assistant" (mainly because of his lack of experience), assigned the legal aspects of the Navy General Command. Prat performed a complete remodeling of the army's legal system, starting with the Navigation Law. He presented 152 modifications to it, many of which were approved. He was also in charge of the regularization of the promotion system, proposing changes to avoid social relations, politics and other factors, making it a merit and seniority based system. Prat died without this navy code having been published. "Observaciones a la ley electoral vigente" This was Arturo Prat's thesis book, which contained many clues about his political thoughts. It was written within the framework of the promulgation of the new electoral law during Federico Errázuriz Zañartu's government, in which the Greater Taxpayer Institution and Parliament Member Cumulative Vote were established. Prat analyzes this law with the perspective that it would make possible further progress towards electoral freedom. He points out the contradictions and obscurity of the text, but he stresses that it is an "eminently liberal" law. Prat ends saying: ...deep-down a good law, it needs serious and important reforms with respect to regulations if it is to achieve the lofty objective it is destined to: to be the effective guarantee that the voting result is the happy expression of the national will." The text reveals Prat's political ideas, clearly reflecting the common liberalism of the times, and demonstrates a great naivety (not even with all of its indications could the law prevent the intervention of the executive power.) Family life Engagement and matrimony Pedro Chacón used to throw parties in his portside house once or twice a week. Prat frequently attended, as did Concepción Chacón's sister-in-law, Carmela Carvajal.
