Antonio S. Quiogue, Jr. vs. Maria Bel B. Quiogue and the Republic
Case
G.R. No. 203992
Decision Date
Aug 22, 2022
Marriage nullified due to Antonio's chronic infidelity rooted in narcissistic personality disorder, deemed psychological incapacity under Article 36.

Case Summary (G.R. No. 218738)

Procedural History

The Regional Trial Court (Quezon City, Branch 88) granted petitioner’s petition for declaration of nullity, finding both spouses psychologically incapacitated. The Court of Appeals reversed and dismissed the petition. The Supreme Court reviewed the CA decision by petition for review on certiorari under Rule 45 and reversed the CA, declaring the marriage void on the ground of the petitioner’s psychological incapacity.

Core Facts and Contentions

Petitioner alleged that both spouses were psychologically incapacitated to comply with essential marital obligations, asserted lack of mutual love and respect, and recounted separation after being driven from the conjugal home in 1998. Respondent denied those allegations and attributed the separation to petitioner’s persistent womanizing, nocturnal gambling, intoxication, verbal abuse, and threats. Witnesses included an office staff (Gemarie Martin) who corroborated episodes of petitioner being sent away and the receipt of vulgar faxes/letters, and the spouses’ eldest daughter who testified to awareness of petitioner’s girlfriends and cohabitation with another woman.

Expert Evidence — Psychiatric Evaluation

Psychiatrist Dr. Valentina Del Fonso Garcia conducted clinical interviews and a mental status assessment (including interviews of petitioner, the eldest daughter, and interviews of respondent in connection with treatment for the couple’s daughter). In an evaluation dated October 29, 2001, Dr. Garcia diagnosed petitioner with narcissistic and histrionic personality disorders, identified antecedent personality traits traceable to childhood and adolescence (including exposure to an unfaithful father and emotional deprivation), and concluded that petitioner’s pattern of chronic infidelity and related traits manifested a grave psychological incapacity that was persistent and not amenable to effective psychiatric remediation as to the marital relationship.

RTC Finding and Rationale

The trial court accepted the psychiatric evaluation and the testimonial evidence, concluding that both spouses were psychologically incapacitated to perform essential marital obligations (living together, mutual love, respect, fidelity, and mutual help and support). The RTC declared the marriage void under Article 36 of the Family Code.

Court of Appeals Ruling

The Court of Appeals reversed the RTC, agreeing with the Solicitor General’s position that petitioner’s acts of infidelity and irreconcilable differences did not meet the standard for psychological incapacity under Article 36. The CA held that Dr. Garcia’s psychiatric report merely confirmed marital problems and was not conclusive proof of a legally cognizable psychological incapacity; it characterized the evidence as more properly supporting legal separation rather than nullity.

Issues Presented on Review

The Supreme Court addressed whether petitioner established the elements of psychological incapacity under Article 36 — specifically: (1) gravity (serious incapacity to perform essential marital obligations), (2) antecedence (existence of the incapacity at the time of marriage), and (3) incurability or persistence of the incapacity in the legal sense — and whether Dr. Garcia’s psychiatric evaluation and the totality of other evidence sufficed to prove those elements.

Legal Standard — Article 36 and Evolving Jurisprudence

Article 36 requires a showing of psychological incapacity to comply with essential marital obligations. The Court recapitulated the jurisprudential development: earlier characterizations of “mental incapacity” (Santos) and the Molina framework (which emphasized medical proof and incurability) were refined by later decisions (e.g., Marcos and Tan‑Andal). The Court reaffirmed that medical proof or formal clinical testing is not indispensable where the totality of credible evidence demonstrates the legal requisites of antecedence, gravity, and persistence (legal incurability) with respect to a specific marital partner.

Application to the Facts — Antecedence

The Court found that Dr. Garcia’s evaluation and supporting testimony demonstrated that petitioner’s proclivity to pursue multiple concurrent or successive sexual relationships had origins in his formative years (exposure to a philandering father, emotional deprivation) and predated the marriage. The psychiatric account and petitioner’s own admissions established that the patterns were longstanding and not recent developments, satisfying antecedence as required by Article 36.

Application to the Facts — Gravity and Legal Incurability

On gravity, the Court emphasized petitioner’s chronic and admitted infidelity, his lack of genuine remorse or recognition of fidelity as an essential marital obligation, and his testimony that he would “always be cheating.” These facts, together with Dr. Garcia’s diagnosis and the corroborating witness testimony (daughter, office staff, documentary materials such a
