Grave and incurable
To declare a marriage void on the ground of psychological incapacity of one of the spouses, the totality of the evidence must prove that the incapacity is mental, not physical, which causes a party to be truly incapable of recognizing and fulfilling the basic marital covenants. It must be characterized by gravity, juridical antecedence and incurability. This is explained and illustrated in this case of Andy and Mely.
