MENDOZA, J.:
Petitioner Ernesto S. Mercado and private respondent Eduardo B. Manzano were candidates for vice mayor of the City of Makati in the May 11, 1998 elections. The other one was Gabriel V. Daza III. The results of the election were as follows:
Eduardo B. Manzano 103,853
Ernesto S. Mercado 100,894
Gabriel V. Daza III 54,275[1]
The proclamation of private respondent was suspended in view of a pending petition for disqualification filed by a certain Ernesto Mamaril who alleged that private respondent was not a citizen of the Philippines but of the United States.
In its resolution, dated May 7, 1998,[2] the Second Division of the COMELEC granted the petition of Mamaril and ordered the cancellation of the certificate of candidacy of private respondent on the ground that he is a dual citizen and, under §40(d) of the Local Government Code, persons with dual citizenship are disqualified from running for any elective position. The COMELEC’s Second Division said:
What is presented before the Commission is a petition for disqualification of Eduardo Barrios Manzano as candidate for the office of Vice-Mayor of Makati City in the May 11, 1998 elections. The petition is based on the ground that the respondent is an American citizen based on the record of the Bureau of Immigration and misrepresented himself as a natural-born Filipino citizen.
In his answer to the petition filed on April 27, 1998, the respondent admitted that he is registered as a foreigner with the Bureau of Immigration under Alien Certificate of Registration No. B-31632 and alleged that he is a Filipino citizen because he was born in 1955 of a Filipino father and a Filipino mother. He was born in the United States, San Francisco, California, on September 14, 1955,
