Tan-Andal v. Andal | Psychological Incapacity [Bar Exam Study Notes]

Tan-Andal v. Andal

G.R. No. 196359 · May 11, 2021 · En Banc · Leonen, J.

THE HOLDING IN ONE LINE. Psychological incapacity under Article 36 is a legal concept, not a medical one. It need not be a mental disorder, it need not be proved by a psychiatrist or psychologist, and it is “incurable” only in the legal sense. What must be proved, by clear and convincing evidence, is an enduring personality structure that makes a spouse unable to understand and comply with the essential marital obligations.

How the doctrine moved

Three cases, twenty-six years. The third one undid part of the second.

1995

Santos v. CA

First defined psychological incapacity as a mental (not physical) incapacity, confined to the “most serious cases of personality disorders.” Adopted the three criteria: gravity, juridical antecedence, incurability.

1997

Republic v. Molina

Laid down eight guidelines. The second required the root cause to be medically or clinically identified and proven by experts. In practice this made Article 36 nearly impossible to invoke without a psychiatric diagnosis.

2021 · Controlling

Tan-Andal v. Andal

En Banc categorically abandons the second Molina guideline and amends the third. Expert opinion is no longer required. Incurability is legal, not medical. The standard of proof is clear and convincing evidence.

The requisites as they now stand

1.Juridical antecedence

RETAINED — it is an explicit requirement of the law. Article 36 says the incapacity must exist “at the time of the celebration” of the marriage, even if it becomes manifest only afterwards. Proof may consist of testimony describing the environment the spouse grew up in, or past experiences that produced the behaviour. This is what separates Article 36 from divorce, which severs a marriage for causes arising after the wedding.

2.Gravity

RETAINED BUT REFRAMED — not in the sense that the incapacity must be a serious or dangerous illness, but to exclude “mild characterological peculiarities, mood changes, occasional emotional outbursts.” It cannot be mere “refusal, neglect or difficulty, much less ill will.” It must be caused by a genuinely serious psychic cause.

3.Incurability — in the legal sense

AMENDED — the incapacity is incurable not in the medical but in the legal sense. It means the incapacity is so enduring and persistent with respect to a specific partner that the couple's personality structures are so incompatible and antagonistic that the only result of the union would be the inevitable and irreparable breakdown of the marriage.

4.Clear and convincing evidence

THE STANDARD OF PROOF — more than preponderance of evidence, less than proof beyond reasonable doubt. It is the quantum required to overcome the presumption in favour of the validity of marriage. Note that this is higher than the ordinary civil standard.

What happened to the Molina guidelines

Guideline	Status	What Tan-Andal did
2nd — root cause medically or clinically identified and proven by experts	Abandoned	“This Court now categorically abandons the second Molina guideline.” Psychological incapacity is neither a mental incapacity nor a personality disorder that must be proven through expert opinion. Ordinary witnesses who knew the spouse before the marriage may testify to behaviours they consistently observed; the judge decides.
3rd — incurability	Amended	Incurable in the legal, not the medical sense. Justice M. Lopez's concurrence supplied the clinching argument: if it were truly incurable, the law could not allow the spouse to remarry.
1st — burden of proof on the plaintiff	Retained	Now expressly quantified as clear and convincing evidence.
Juridical antecedence and gravity	Retained	Retained, but redefined as above — behavioural and legal, not clinical.

Quotes worth memorising

To summarize, psychological incapacity consists of clear acts of dysfunctionality that show a lack of understanding and concomitant compliance with one's essential marital obligations due to psychic causes. It is not a medical illness that has to be medically or clinically identified; hence, expert opinion is not required. Leonen, J., for the Court En Banc

There must be proof… of the durable or enduring aspects of a person's personality, called “personality structure,” which manifests itself through clear acts of dysfunctionality that undermines the family… Proof of these aspects of personality need not be given by an expert. On abandoning the second Molina guideline

A psychologically incapacitated person need not be shamed and pathologized for what could have been a simple mistake in one's choice of intimate partner, a mistake too easy to make as when one sees through rose-colored glasses. The dignity rationale — quotable in any essay on Article 36

The case itself

Facts. Rosanna Tan and Mario Victor Andal married in December 1995. Mario was a drug user; he was often absent, financially unreliable, and behaved erratically. Rosanna eventually separated from him and petitioned for declaration of nullity under Article 36. Dr. Valentina Garcia, a psychiatrist, testified that Mario suffered from a narcissistic antisocial personality disorder that was grave, juridically antecedent and incurable — an opinion formed without interviewing Mario himself.

Trial court. Declared the marriage void ab initio, awarded custody of the child to Rosanna, and declared her the sole owner of the Parañaque property.

Court of Appeals. Reversed. It discounted Dr. Garcia's opinion wholesale as “unscientific and unreliable” because she never examined Mario, and held the marriage valid and subsisting.

Supreme Court. Petition GRANTED. The Court of Appeals decision was reversed and set aside and the trial court's decision reinstated. The Court held that the Court of Appeals erred in discarding the expert opinion — expert witnesses do not testify from personal knowledge but from special knowledge, skill, experience or training. In any event, expert opinion is no longer required; it was considered here only because it had been offered in evidence.

How this gets asked in the Bar

The clean question. “A files a petition under Article 36 but presents no psychologist or psychiatrist, offering only the testimony of A's sibling and a childhood friend of B. The OSG moves to dismiss for failure to prove the root cause through expert evidence. Rule.” → Deny the motion. Tan-Andal abandoned the second Molina guideline; ordinary witnesses who knew the spouse before the marriage may testify to consistently observed behaviours, and from there the judge decides.

Trap 1 — “so Tan-Andal made it easy.” It did not. The Court raised the standard of proof to clear and convincing evidence, above the ordinary civil standard of preponderance. What was relaxed is the kind of evidence, not the quantum.

Trap 2 — “expert testimony is now inadmissible.” Wrong. It is no longer required. If offered, it is still received and weighed — exactly what the Court did with Dr. Garcia's opinion.

Trap 3 — treating Article 36 as divorce. Juridical antecedence survives. The incapacity must have existed at the celebration of the marriage. A cause that developed after the wedding is not psychological incapacity — that distinction is the whole reason antecedence was retained.

Trap 4 — reciting all eight Molina guidelines as still controlling. The second is abandoned and the third amended. An answer that recites Molina wholesale is answering a 1997 question in a 2026 exam.

Read with this one. Santos v. Court of Appeals, 310 Phil. 21 (1995) — the original definition. Republic v. Court of Appeals and Molina, 335 Phil. 664 (1997) — the eight guidelines. Tortona v. Gregorio — the standards for admitting expert opinion, applied in Tan-Andal. Note also the separate concurring opinions, especially Justice M. Lopez on why “incurable” cannot have been meant medically.
