(1) In addition to any other grounds on which a marriage is by law void or voidable, a marriage is, subject to subsection (2) voidable on the ground—
(a) that the marriage has not been consummated owing to the wilful refusal of the respondent to consummate it; or
(b) that at the time of the marriage, either party to the marriage—
(i) was suffering from mental disorder of such a kind or to such an extent as to be unfitted for marriage and the procreation of children, or
(ii) was subject to recurrent attacks of insanity or epilepsy;
(c) that the respondent was at the time of the marriage suffering from venereal disease in a communicable form; or
(d) that the respondent was at the time of the marriage pregnant by some person other than the petitioner.
(2) The Court shall not grant a decree of nullity in a case falling within subsection (1)(b), (1)(c) or (1)(d) unless it is satisfied that—
(a) the petitioner was at the time of the marriage ignorant of the facts alleged;
(b) proceedings were instituted within a year from the date of the marriage; and
(c) marital intercourse with the consent of the petitioner has not taken place since the petitioner discovered the existence of the grounds for a decree.
(3) This section shall not be construed as validating a marriage which is by law void but with respect to which a decree of nullity has not been granted.
