Effect of judgment of nullity in case of voidable marriage
110.—(1)  If the court finds that the plaintiff’s case has been proved, it shall grant a judgment of nullity.
(2)  A judgment of nullity granted after 1 June 1981 on the ground that a marriage is voidable operates to annul the marriage only as respects any time after the judgment has been made final, and the marriage shall, despite the judgment, be treated as if it had existed up to that time.
