I disagree to @ Nadeem and to @ Assumi. You should follow what the ld. Judge said which you clearly misunderstood.
Delhi HC Rules states clearly that if the petition is for a decree of nullity of marriage on the grounds specified in clauses (c) and (d) of sub-section (1) of S. 12 of The Act (HMA) the petitioner should move a Petition under S. 12 of The Act (HMA) for annulment of marriage by a decree of nullity and not under S. 13 of The Act (HMA).
The ground of queriest which he has prayed as per his own brief is; the consent for marriage was taken by ‘force’ or were taken under ‘undue influence’.
Delhi High Court in one of its land mark judgment ref.: Mr. Ranjit Thomas Vs. Ms. Annie R. Thomas [93 (2001) DLT 271, II (2001) DMC 419, 2001 (59) DRJ 515] had held:
"Thus if a party to a marriage gives consent either under the influence of parents or to avoid and escape their wrath or disagreement or under their or any other kin's threat to harm themselves or the disagreeing party to the marriage or through the implorings of saving the honour of the family or parents satisfaction, such a consent lacks element of voluntariness and volition as it is smeared with duress and force."
"Instant wedlock turned into a deadlock at its very inception. Parties hardly stayed for a week together and that too without any response to marital advances of the petitioner. Dismayed at such a conduct of the respondent, the petitioner asked her about her indifferent attitude. She disclosed that she was not interested in marrying him and gave the consent at the instance of her parents and for their satisfaction. It appears that her physical and mental strength succumbed under filial force and obedience. It was not a consent free from force or duress and, therefore, neither voluntary nor volitional."
"As a result, the petition is allowed and marriage is hereby declared as null and void by way of a decree of nullity."
