NEW DELHI, July 8: The Supreme Court Thursday termed âimportant” the pleas challenging Constitutional validity of the matrimonial law provisions which empower courts to ask estranged spouses to “cohabit” and “take part in sexual intercourse” to restore conjugal rights and asked the Centre to file its response within 10 days. A bench of Justices R F Nariman, K M Joseph and B R Gavai listed the pleas for further hearing on July 22 and allowed various intervention applications. During the brief hearing, Attorney General K K Venugopal, whose assistance was sought by the court in the matter, said he needed time to file written submissions.
