C. CITIZENSHIP AND DOMICILE
         Whether Grace Poe is eligible to sit as a Senator of the Republic.
         HELD:
         From the deliberations of the 1934 Constitutional Convention on citizenship, it was never the
         intention of the framers to exclude foundlings from natural-born citizenship status.
          “Children or people born in a country of unknown parents are citizens of this nation” and the only
         reason that there was no specific reference to foundlings in the 1935 provision was that these
         cases “are few and far in between.”
         Evident intent was to adopt the concept found in the Spanish Code “wherein all children of
         unknown parentage born in Spanish territory are considered Spaniards, because the presumption is
         that a child of unknown parentage is the son of a Spaniard.”
         Under Art. 14 of the Hague Convention of 1930 (on Conflict of Nationality Laws), a foundling is
         presumed to have been born on the territory of the State in which it was found until the contrary is
         proved.
         Although the Philippines is not a signatory to said convention, its provisions are binding as they
         form part of the law of the land pursuant to the incorporation clause.
         Hence, foundlings (children born in the Philippines with unknown parentage) were, by birth,
         accorded natural-born citizenship by the Constitution.
         “natural-born citizens by legal fiction”
         The framers of the Constitution were sufficiently empowered to create a class of natural-born
         citizens by legal fiction, as an exception to the jus sanguinis rule
         This is evident from Art. 1 (State to determine who are its nationals) and Art. 2 (questions on
         nationality to be determined by the law of that State) of the 1930 Hague Convention
         Poe validly reacquired her natural-born Filipino citizenship upon taking her Oath of Allegiance to
         the Republic, as required under Section 3, R.A. No. 9225
         Before assuming her position as MTRCB Chairman, Poe executed an affidavit of renunciation of
         foreign citizenship. This was sufficient to qualify her for her appointive position, and later, her
         elective office as R.A. No. 9225 did not require that her Certificate of Loss of Nationality filed before
         the U.S. Embassy be first approved in order that she may qualify for office.
         Records of the Bureau of Immigration show that Poe still used her U.S. passport after having taken
         her Oath of Allegiance but not after she has renounced her U.S. Citizenship.
