Nationalization of Education Law of June 1961, and the Second Agrarian Reform Law of October 1963. Furthermore, new institutions, such as the National Institute of Agrarian Reform (INRA), were created to carry out these laws more efficiently. Revolutionary courts In February 1962, 45 Cuban Air Force officers were tried for genocide in the civilian courts and were acquitted. Their acquittal was publicly denounced by Fidel Castro as a miscarriage of justice. In response to the verdict, the Revolutionary Government established "Revolutionary Courts," whose purpose was to try those accused of collaboration with the deposed Batista regime, especially those accused of torture and assassination, and those engaged in counterrevolutionary activity. These courts were criticized for their summary procedures, which limited a defendant's ability to prepare for trial, as well as procedural safeguards, such as the right to appeal a verdict of guilt. It has been noted the effect of the courts was to produce a fast, certain, and severe result. In all, hundreds of individuals were found guilty in these proceedings and subsequently executed.

First established in the rural areas of the country, there were more than 2,200 such courts by the end of the 1960s. The proceedings of these courts were opened to the public in an effort to maximize their effect. These courts were criticized for overlapping with the jurisdiction of other courts and for their inconsistent application of the law. Institutionalization (mid-1970s–late 1980s) Need for new legal system As the 1960s drew to a close, the most radical phase of the revolution had passed and internal counter-revolution had been suppressed. The Cuban government sought to institutionalize the Revolution. Key to this was the creation of a new legal system. 1973 Reforms In 1973, the Cuban Council of Ministers approved a structure for the new legal system, abolishing the People's Popular Courts and the Revolutionary Courts. In the place of the old legal system, a
