Supreme Court: Tan-Andal v. Andal (G.R. No. 196359, May 11, 2021)
The text of Article 36 has not changed, but the Supreme Court changed how it is applied. Psychological incapacity is a legal concept, not a medical illness or personality disorder. It need not be proven by expert testimony from a psychologist or psychiatrist; ordinary witnesses who knew the spouse before the marriage can describe their behavior. It must still be grave, existing at the time of the marriage (juridical antecedence) and incurable in the legal sense, and it must be proven by clear and convincing evidence. Earlier tests from Molina (1997) that required a medically identified root cause are abandoned.
