FACTS: Respondent Teodoro Cruz was a natural-born citizen of the Philippines. He was born in San Clemente, Tarlac, on April 27, 1960, of Filipino parents. The fundamental law then applicable was the 1935 Constitution. On November 5, 1985, however, respondent Cruz enlisted in the United States Marine Corps and without the consent of the Republic of the Philippines, took an oath of allegiance to the United States. As a Consequence, he lost his Filipino citizenship for under Commonwealth Act No. 63, section 1(4), a Filipino citizen may lose his citizenship by, among other, "rendering service to or accepting commission in the armed forces of a foreign country.” He was naturalized in US in 1990. On March 17, 1994, respondent Cruz reacquired his Philippine citizenship through repatriation under Republic Act No. 2630. He ran for and was elected as the Representative of the Second District of Pangasinan in the May 11, 1998 elections. He won over petitioner Antonio Bengson III, who was then running for reelection.
ISSUE: Whether or Not respondent Cruz is a natural born citizen of the Philippines in view of the constitutional requirement that "no person shall be a Member of the House of Representative unless he is a natural-born citizen.”
RATIO DECIDENDI: Respondent is a natural born citizen of the Philippines. As distinguished from the lengthy process of naturalization, repatriation simply consists of the taking of an oath of allegiance to the Republic of the Philippine and registering said oath in the Local Civil Registry of the place where the person concerned resides or last resided. This means that a naturalized Filipino who lost his citizenship will be restored to his prior status as a naturalized Filipino citizen. On the other hand, if he was originally a natural-born citizen before he lost his Philippine citizenship, he will be restored to his former status as a natural-born Filipino.
