for a Portuguese passport despite his naturalization as a
Philippine citizen and his act of declaring his nationality

Co v. HRET- representative; 2nd District of Samar; election of
citizenship The exercise of the right to suffrage and the
participation in electionexercises constitute a positive act of
election of Philippine citizenship; Any election of Philippine
citizenship on the part of Jose Ongwould not only have been
superfluous but would also have resulted in absurdity considering
that it was the law itself that hadalready elected Philippine
citizenship for him.
In re: Chingpermission to take the lawyers oath; Ching elected
Filipino citizenship beyond the required uponreaching the age of
majority If the citizenship of a person was subject to challenge
under the old charter, it remains subject tochallenge under the new
charter even if the judicial challenge had not been commenced
before the effectivity of the newConstitution; CA 625 and the 1935
Constitution did not prescribe a time within which the election of
Philippine citizenship should bemade; reasonable time; upon
reaching the age of majority it was clearly beyond by any
reasonable yardstick, the able period toexercise the privilege.
