FACTS
Petitioner Ernesto S. Mercado (Mercado) and private respondent Eduardo B. Manzano (Manzano) were candidates for vice mayor of the City of Makati in the May 1998 elections. Respondent won. A certain Ernesto Mamaril (Mamaril) filed a petition for disqualification against Manzano on the ground that he was not a citizen of the Philippines but of the United States. Commission on Election (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.
According to COMELEC, respondent admitted that he is registered as a foreigner with the Bureau of Immigration 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, September 14, 1955, and is considered in American citizen under US Laws. But notwithstanding his registration as an American citizen, he did not lose his Filipino citizenship. Thus, he is considered as dual citizen. And as a law, persons with dual citizenship are disqualified from running for any elective position.
Private respondent filed a motion for reconsideration.3 The motion remained pending even until after the election held on May 11, 1998. petitioner sought to intervene in the case for disqualification.4 Petitioner's motion was opposed by private respondent. The motion was not resolved. Instead, on August 31, 1998, the COMELEC en banc rendered its resolution in favor of Manzano. respondent Eduardo Barrios Manzano was born in San Francisco, California, U.S.A. He acquired US citizenship by operation of the United States Constitution and laws under the principle of jus soli. He was also a natural born Filipino citizen by operation of the 1935 Philippine Constitution, as his father and mother were Filipinos at the time of his birth.
Petitioner contends that COMELEC en banc ERRED in holding that:
A. Under Philippine law, Manzano was no longer a U.S. citizen when he:
1. He renounced his U.S. citizenship when he attained the age of majority when he was
already 37 years old; and,
2. He renounced his U.S. citizenship when he (merely) registered himself as a voter and
voted in the elections of 1992, 1995 and 1998.
B. Manzano is qualified to run for and or hold the elective office of Vice-Mayor of the City of Makati;
C. At the time of the May 11, 1998 elections, the resolution of the Second Division adopted on 7 May 1998 was not yet final so that, effectively, petitioner may not be declared the winner even assuming that Manzano is disqualified to run for and hold the elective office of Vice-Mayor of the City of Makati.
Hence, this petition for certiorari.
ISSUE
Whether or not respondent Manzano is a dual citizen and cannot run for public office.
HELD
To begin with, dual citizenship is different from dual allegiance. The former arises when, as a result of the concurrent application of the different laws of two or more states, a person is simultaneously considered a national by the said states. For instance, such a situation may arise when a person whose parents are citizens of a state which adheres to the principle of jus sanguinis is born in a state which follows the doctrine of jus soli. Such a person, ipso facto and without any voluntary act on his part, is concurrently considered a citizen of both states. Considering the citizenship clause (Art. IV) of our Constitution, it is possible for the following classes of citizens of the Philippines to possess dual citizenship:
1. Those born of Filipino fathers and/or mothers in foreign countries which follow the principle of jus soli;
2. Those born in the Philippines of Filipino mothers and alien fathers if by the laws of their fathers’ country such children are citizens of that country;
3. Those who marry aliens if by the laws of the latter’s country the former are considered citizens, unless by their act or omission they are deemed to have renounced Philippine citizenship.
There may be other situations in which a citizen of the Philippines may, without performing any act, be also a citizen of another state; but the above cases are clearly possible given the constitutional provisions on citizenship.
Dual allegiance, on the other hand, refers to the situation in which a person simultaneously owes, by some positive act, loyalty to two or more states. While dual citizenship is involuntary, dual allegiance is the result of an individual’s volition.
The phrase “dual citizenship” in the Local Government Code must be understood as referring to “dual allegiance.” Consequently, persons with mere dual citizenship do not fall under this disqualification. Unlike those with dual allegiance, who must, therefore, be subject to strict process with respect to the termination of their status, for candidates with dual citizenship, it would suffice if, upon the filing of their certificates of candidacy, they elect Philippine citizenship to terminate their status as persons with dual citizenship considering that their condition is the unavoidable consequence of conflicting laws of different states.
By electing Philippine citizenship, such candidates at the same time forswear allegiance to the other country of which they are also citizens and thereby terminate their status as dual citizens. It may be that, from the point of view of the foreign state and of its laws, such an individual has not effectively renounced his foreign citizenship. That is of no moment.
The COMELEC en banc’s ruling was that Manzano’s act of registering himself as a voter was an effective renunciation of his American citizenship. This ruling is in line with the US Immigration and Nationality Act wherein it is provided that “a person who is a national of the United States, whether by birth or naturalization, shall lose his nationality by: (e) Voting in a political election in a foreign state or participating in an election or plebiscite to determine the sovereignty over foreign territory.” But this provision was declared unconstitutional by the US Supreme Court. Nevertheless, our SC held that by filing a certificate of candidacy when he ran for his present post, private respondent elected Philippine citizenship and in effect renounced his American citizenship.
To recapitulate, by declaring in his certificate of candidacy that he is a Filipino citizen; that he is not a permanent resident or immigrant of another country; that he will defend and support the Constitution of the Philippines and bear true faith and allegiance thereto and that he does so without mental reservation, private respondent has, as far as the laws of this country are concerned, effectively repudiated his American citizenship and anything which he may have said before as a dual citizen.
On the other hand, private respondent’s oath of allegiance to the Philippines, when considered with the fact that he has spent his youth and adulthood, received his education, practiced his profession as an artist, and taken part in past elections in this country, leaves no doubt of his election of Philippine citizenship.
His declarations will be taken upon the faith that he will fulfil his undertaking made under oath. Should he betray that trust, there are enough sanctions for declaring the loss of his Philippine citizenship through expatriation in appropriate proceedings. In Yu v. Defensor-Santiago, we sustained the denial of entry into the country of petitioner on the ground that, after taking his oath as a naturalized citizen, he applied for the renewal of his Portuguese passport and declared in commercial documents executed abroad that he was a Portuguese national. A similar sanction can be taken against anyone who, in electing Philippine citizenship, renounces his foreign nationality, but subsequently does some act constituting renunciation of his Philippine citizenship.
