Case Summary (G.R. No. 209278)

Key Dates and Procedural Posture

Alfredo filed a complaint for declaration of nullity of marriage on January 3, 2005 before the Regional Trial Court (RTC) of Olongapo City. The RTC rendered judgment declaring the marriage void for respondent’s psychological incapacity on September 25, 2007. The Court of Appeals affirmed on September 28, 2012 and denied reconsideration on September 18, 2013. Irene filed a petition for review on certiorari with the Supreme Court, which denied the petition and affirmed the CA judgments (G.R. No. 209278; decision rendered in 2021).

Applicable Law and Constitutional Basis

Article 36 of the Family Code (as interpreted under the 1987 Constitution, applicable given the decision date) provides that a marriage contracted by a party psychologically incapacitated to comply with essential marital obligations is void. The controlling doctrinal framework quoted and applied includes the Supreme Court’s clarification that psychological incapacity is a legal—not a strictly medical—concept (Tan-Andal v. Andal), and the evidentiary and doctrinal contours articulated in prior cases (including Republic v. Court of Appeals and Molina and the criminal-context discussion in People v. Madarang).

Factual Findings Established at Trial

The trial record includes testimony that Alfredo was discharged from U.S. Navy service for psychiatric/medical reasons and that he exhibited delusions and religiously framed claims (e.g., believing himself an emissary or son of God, claiming divine orders to leave his wife and to abstain from working, and asserting entitlement to multiple wives). Imputed or actual financial support and benefits were received: Irene acknowledged receiving a United States Veterans Affairs pension apportionment attributable to Alfredo’s disability. Irene also admitted differences in religious beliefs and that she had separated because Alfredo had another woman in his life.

Expert and Documentary Evidence

Alfredo offered expert testimony from clinical psychologist Martha Johanna D. Dela Cruz, who evaluated him and opined that he suffered from schizophrenia, paranoid type, with impaired judgment and a chronic course; she further diagnosed a shared psychotic disorder in Irene based on her written declination of evaluation. The record also includes a medical certificate by Dr. Jose Rommel T. Soriano and written findings from the United States Veterans Affairs Office indicating psychosis-related benefits; the trial court and appellate tribunal relied on these materials together with testimonial corroboration.

Trial Court’s Legal Analysis and Holding

The RTC found that Alfredo had a pre-existing schizophrenic disorder constituting an enduring part of his personality structure, manifested in sustained dysfunction that undermined the marital relationship. The court concluded that Alfredo’s incapacity was grave, had juridical antecedence (existed before marriage), and was incurable in the context of the marriage, thereby satisfying the statutory elements for nullity under Article 36. The RTC declared the marriage null and void, ordered continued child support obligations by Alfredo, and recognized visitation rights.

Appellate and Supreme Court Review Standards Applied

The Supreme Court reiterated that a petition for review on certiorari under Rule 45 raises only questions of law and that findings of fact of the CA are generally binding unless one of the well-established exceptions applies (e.g., findings based on conjecture, manifestly mistaken inferences, grave abuse of discretion, misapprehension of facts, or findings contradicted by the record). The Court found no ground to disturb the lower courts’ factual findings and expert-appreciation conclusions under those exceptions.

Legal Standard for Psychological Incapacity Explained

The Court reiterated that psychological incapacity is a legal concept entailing a durable personality structure that manifests through acts of dysfunctionality preventing compliance with essential marital obligations (Articles 68–71 and related provisions). Three interrelated characteristics—gravity, juridical antecedence, and incurability—must be demonstrated by clear and convincing evidence; however, the condition need not be reducible to a diagnosable medical illness, and a medical label (e.g., schizophrenia) does not automatically equate to legal psychological incapacity.

Application of Law to the Case Facts

Applying the legal standard, the Supreme Court concluded that Alfredo’s psychosis, regardless of its medical label, constituted an enduring personality trait that produced concrete, recurrent dysfunctional acts: refusal to live with his wife and to provide support by virtue of his claimed divine orders; delusions permitting polygamous conduct; hallucinations and commands that undermined mutual love, respect, fidelity, and support; and a long-standing course (decades) without meaningful improvement. The Court held that these facts established the requisite gravity, juridical antecedence, and relative incurability (permanence in relation to this marital relationship), thereby satisfying Article 36’s elements.

Evidentiary Sufficiency and Treatment of Challenges to Evidence

Irene challenged the competence and authentication of certain documents (U.S. Veterans Affairs findings and Dr. Soriano’s certificate) and attempted to minimize the psychiatric evidence. The Supreme Court found that even if some documenta
