Arellano, was born to Don Servando Arellano, an overseer of the Friar Estates and an official of the Tobacco Monopoly, and Doña Crisfora Lonzon on March 2, 1847, in Orion, Bataan. After receiving his primary and secondary education at Letran, he transferred to Santo Tomas where he finished with a Bachelor in Canon and Civil Laws in 1871 and Licenciado en Jurisprudencia in 1876. He then practised law and taught at Santo Tomas. In 1879, he was named juez de residencia of Tarlak, assistant justice of the Audiencia Tribunal of Manila, and Manila city councilor in 1887-1889. Arellano did not participate actively in the revolution, and when offered the position of Secretary of Foreign Relations in the Malolos Republic, he declined because Aguinaldo had refused to release friar prisoners, according to Alejandrino. Nevertheless, he helped Felipe Calderon in drafting the Malolos Constitutions. At the start of the American sovereignty in the Philippines early in 1899, Arellano cooperated with General Otis in the organization of the courts, in the preparation of the Marriage Law, the Municipal Code and the Code of Criminal Procedure. He was made chairman of the Civil Service Board and was appointed Chief Justice of the Supreme Court in June, 1899. Arellano was married to the former Rosa Bernar by whom he had one daughter, Asuncion, later married to Dr. Gregorio Singian. He died on December 23, 1920.
