"The foregoing guidelines have turned out to be rigid, such that their application to every instance practically condemned the petitions for declaration of nullity to the fate of certain rejection. But Article 36 of the Family Code must not be so strictly and too literally read and applied given the clear intendment of the drafters to adopt its enacted version of “less specificity” obviously to enable “some resiliency in its application.” Instead, every court should approach the issue of nullity “not on the basis of a priori assumptions, predilections or generalizations, but according to its own facts” in recognition of the verity that no case would be on “all fours” with the next one in the field of psychological incapacity as a ground for the nullity of marriage; hence, every “trial judge must take pains in examining the factual milieu and the appellate court must, as much as possible, avoid substituting its own judgment for that of the trial court.”10."
