Baltasar Corrada del Río (April 10, 1935 – March 11, 2018) was a Puerto Rican politician. He held various high political offices in the island, including President of the Puerto Rico Civil Rights Commission, Resident Commissioner (1977–1985), Mayor of the capital city of San Juan (1985–1989), Puerto Rico's 15th Secretary of State (1993–1995) and Associate Justice of the Supreme Court (1995–2005). He was also the unsuccessful NPP candidate for Governor in the elections of 1988. Education Corrada del Río obtained his high school diploma from Colegio Ponceño de Varones in 1952, and both his bachelor's degree in Social Studies in 1956 and his law degree from the University of Puerto Rico in 1959. He was admitted to the Puerto Rico Bar that year and practiced as a private lawyer from 1969 to 1975. Political career In 1976, after initially expressing an interest in becoming Mayor of San Juan and running in an unofficial internal primary within the NPP, Corrada del Río was elected Resident Commissioner of Puerto Rico. During his tenure (1977–1985), he advocated for the admission of Puerto Rico into the Union and co-founded the Congressional Hispanic Caucus Institute. Corrada served as Mayor of San Juan, Puerto Rico, from 1985 to 1989 (having won the 1984 mayoral election). In the elections of 1988, Corrada made an unsuccessful bid to become Governor of Puerto Rico. He was defeated by incumbent Governor Rafael Hernández Colón. In January 1993, Pedro Rosselló became Governor and appointed Corrada as Puerto Rico's 15th Secretary of State. Later, in 1995, Rosselló appointed Corrada as Associate Justice of the Supreme Court of Puerto Rico. He took the oath of office on July 15, 1995, after unanimous confirmation in the Senate of Puerto Rico. During his tenure as Associate Justice, Corrada was among the moderate/conservative voices in the Court, usually adhering to strict interpretations of the Constitution while practicing a firm type of judicial restraint. The Constitution of Puerto Rico mandates an obligatory retirement for the Justices of the Supreme Court at age 70. Corrada arrived at this age in April, 2005, and was forced to retire.
