He was later appointed in 1936 to the Court of Appeals, and became an Associate Justice of the Supreme Court in 1945. He left the Supreme Court in 1948 to become Secretary of Justice under President Elpidio Quirino, but was reinstated a few months later.
In 1966, he became the first Filipino ever to be elected judge of the International Court of Justice. He held this position until 1976.
