1. 1935 Constitutional Rule
Under the 1935 Constitution, the principle of jus sanguinis was primarily applied through paternal lineage. Children born of Filipino fathers automatically acquired Philippine citizenship at birth. However, children born of Filipino mothers and alien fathers did not automatically gain Philippine citizenship; instead, they held an inchoate right and were required to elect Philippine citizenship upon reaching the age of majority. This distinction reflected a traditional preference for paternal transmission of citizenship during that constitutional era, creating a conditional pathway for children of Filipino mothers.

2. 1973 Equality Mandate
The 1973 Constitution eliminated the gender-based disparity in the transmission of Philippine citizenship by birth. Under Section 1(2), Article III of the 1973 Constitution, those whose fathers or mothers are citizens of the Philippines are considered natural-born citizens. This amendment established full equality between male and female Filipino parents regarding jus sanguinis. Consequently, children born to a Filipino mother and an alien father after the ratification of the 1973 Constitution automatically acquired Philippine citizenship at birth without needing to execute a formal election upon reaching majority.

3. 1987 Constitutional Status
The 1987 Constitution preserved equal transmission of citizenship through either parent while clarifying the legal status of individuals born under prior charters. Under Section 1(3), Article IV of the 1987 Constitution, children born of Filipino mothers before January 17, 1973, who elected Philippine citizenship upon reaching majority, are explicitly classified as natural-born citizens. This provision cured the former inequality under the 1935 Constitution by granting full natural-born status to those who complied with the statutory election requirement, reinforcing complete equal protection in citizenship law.
