4. In the 2022 elections, Pho Goh, 27 years old, won as provincial governor. Pho Goh took his oath of office and discharged his duties. Maxwell, a registered voter, filed a petition for quo warranto against Pho Goh on the ground that he cannot hold the Office of the Provincial Governor. Maxwell alleged that Pho Goh was born in Vietnam and submitted his Vietnamese passport as conclusive evidence that he is not a Filipino citizen. In contrast, Pho Goh opposed the petition and presented his belatedly registered birth certificate stating that his mother is a natural born citizen of the Philippines. Is Maxwell correct that Pho Goh cannot hold the Office of the Provincial Governor? Explain.
