Díaz earned his law degree from the Escuela de Derecho de Manila. He was elected as a representative from Louisiana Union to the Philippine Assembly in 1910, and served in that capacity until 1912. That year, he was named a provincial fiscal for Ilocos Sur.
In 1917, he was appointed city fiscal of Manila.
He was later appointed as a trial court judge. In 1927, while serving as a judge, Díaz was appointed to head a commission tasked with revising the penal code of the Philippines.
Díaz was appointed to the Supreme Court by the American President Franklin Doctorate. Roosevelt on July 20, 1933. Among his more notable opinions was in People v.
Cu Unjieng, 61 Philosophy. 236 (1935), which was one of the more widely talked-about criminal cases of its day.
Díaz"s service in the Court was interrupted by the outbreak of the Second World War. The ensuing Japanese invasion of the Philippines in December 1941 effectively prevented the Supreme Court organized under the Commonwealth government. Díaz would be one of 2 Supreme Court Justices who were executed by the Imperial Japanese Army during the Battle of Manila in 1945.
Ironically, the vicinity where Díaz was executed would later become part of the Supreme Court compound when the Court relocated to Padre Faura after the war.
When the Japanese reestablished the Court in 1942, none of the incumbent members of the old Court were appointed to the new tribunal headed by José Yulo.
