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).

[1] 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 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.

Governor Aníbal Acevedo Vilá did not nominate anyone for the position after then-Senate President Kenneth McClintock made it clear in his inaugural speech as Senate president in 2005 that only a well-qualified statehooder would muster the votes for Senate confirmation to Court seats previously held by statehooders in order to assure "balance" on the bench.

[2] Baltasar Corrada del Río died on Sunday March 11, 2018, in Fort Myers, Florida at 82 years of age.

The Congressional Hispanic Caucus Institute (CHCI) issued a medal honoring Corrada and three other founding members.

On November 24, 2010, a ceremony was held at the Puerto Rico Department of State to announce the publication of Baltasar Corrada Del Río-Sus opiniones 1995-2005 a book containing excerpts from 61 of his Supreme Court opinions edited by Pontifical Catholic University Law School dean Angel González Román, at which Acting Governor Kenneth McClintock and Chief Justice Federico Hernandez Denton were the keynote speakers.
