The Supreme Court held that DNA evidence can be used to establish filiation, even when it challenges the presumption of legitimacy of a child born during a valid marriage. This ruling allows a biological father to establish a legal relationship with a child, securing rights like citizenship, support, and inheritance, provided that the best interests of the child are considered. The Court emphasized that while the presumption of legitimacy is important, it should not prevent the establishment of truth when scientific evidence proves otherwise, particularly when the legal father does not contest the claim.

Whose Child Is It Anyway? DNA, Legitimacy, and the Quest for Truth

Bernie Santiago sought to establish his paternity of Maria Sofia Jornacion and correct her birth certificate to reflect his filiation. Sofia was born during her mother Magdalena’s marriage to Rommel Jornacion, though they were separated. Bernie claimed he had a relationship with Magdalena and supported Sofia since birth, but Rommel was listed as Sofia’s father to avoid scandal. After Magdalena’s death, Bernie wanted to legally recognize his paternity, especially since Rommel had allegedly abandoned Sofia. The Regional Trial Court (RTC) and Court of Appeals (CA) dismissed Bernie’s petition, arguing he lacked the legal standing to challenge Sofia’s legitimacy. The Supreme Court (SC) was thus faced with a crucial question: Can DNA evidence override the presumption of legitimacy to establish biological paternity and ensure the child’s welfare?

The Supreme Court reversed the lower courts’ decisions, emphasizing the importance of considering DNA evidence in establishing filiation. The Court acknowledged the long-standing legal principle that maternity is a matter of fact while paternity is a matter of faith, but also recognized that modern science offers a more definitive means of establishing parentage. The case hinged on the interpretation of Article 164 of the Family Code, which presumes that a child born to a married woman is the legitimate child of her husband. However, this presumption is not absolute. Article 166 of the Family Code provides grounds for impugning legitimacy, including biological or other scientific reasons.

The Court underscored that while the law aims to protect the status of legitimacy, it should not be used to suppress the truth, especially when doing so would not serve the child’s best interests. The Court quoted the Family Code, highlighting Article 172, which outlines how legitimate filiation is established, and Article 175, which extends these methods to establishing illegitimate filiation. To support its ruling, the SC cited Estate of Ong v. Diaz, a case with similar factual circumstances, where the Court recognized the relevance of DNA testing in determining paternity. The Court then explained the importance of balancing legal presumptions with scientific evidence in determining filiation.

The Supreme Court clarified that Rule 108 of the Rules of Court is the appropriate adversarial proceeding to effect substantial corrections and changes in the entries of the civil register, including those pertaining to filiation. In this case, the Court found that the lower courts erred in dismissing Bernie’s petition based solely on his lack of legal standing to impugn Sofia’s legitimacy. By emphasizing the primacy of a child’s best interests, the Court balanced the legal framework of presumptions with the reality of scientific proof, setting a precedent for future cases involving filiation and legitimacy.

The Court noted that the OSG argued that only the husband or his heirs can challenge the legitimacy of a child. However, the Supreme Court stated that a strict interpretation of the Family Code would unduly limit the instances in which a child’s filiation with his/her biological father can be established. The Court referred to Phil. International Trading Corp. v. COA, explaining that a statute must be interpreted and understood in its entirety, with every part considered together and kept subservient to the general intent of the whole enactment. To further clarify its legal stance, the Court delved into the concept of presumption within the legal framework.

The Court explained that a presumption is merely an assumption of fact resulting from a rule of law, not evidence itself. While conclusive presumptions are irrefutable, disputable presumptions can be contradicted by other evidence. As the presumption of legitimacy is disputable, it can be overthrown by evidence, including biological or scientific proof. The Court stated that Bernie’s willingness to undergo DNA testing presented an opportunity to overcome the disputable presumption of Sofia’s legitimate status. The Supreme Court further emphasized the importance of considering the welfare of the child as the paramount concern in all actions concerning children. The court cited Pablo-Gualberto v. Gualberto V, explaining that the principle of “best interest of the child” pervades Philippine cases involving adoption, guardianship, support, personal status, minors in conflict with the law, and child custody.

The Supreme Court highlighted that it was not the intent of the legislators to elevate the presumption of legitimacy to a position higher than a proven fact. To further emphasize the use of scientific evidence, the Court acknowledged that A.M. No. 06-11-5-SC or the Rule on DNA Evidence is an acceptance of this accurate scientific breakthrough of determining paternity. According to the said rule, Section 9(c) of the Rule on DNA Evidence categorically states when DNA evidence is considered conclusive proof of non-paternity and when it can be used as proof of paternity. Thus, the Supreme Court then ruled to remand the case to the lower court.
