The Kerala government defended its police before the Supreme Court and said the investigation into the marriage of a Muslim man with a Hindu woman was conducted in "an efficient and honest manner".
The NIA probe into the marriage of Hadiya, who says she converted out of her own free will, and Shafin Jahan was ordered by the Supreme Court.
It may be recalled that the Supreme Court on the last date of hearing had asked how the High Court could annul the marriage.
The affidavit contended that a Special Investigation Team (SIT) of Kerala Police conducted a "detailed investigation" into the conversion of Hadiya and her subsequent marriage to Mr Shafin. Changing its preliminary view, the SC said that a father can not be seen dictating the personal life of a 24-year-old daughter.
However, the department said, the investigation had to be handed over to the NIA by Kerala police in view of the SC order in August. "Two senior BJP functionaries have married members of minority communities", senior advocate Dushyant Dave and advocate Haris Beeran, for Jahan, had argued.
"As women's rights activists from across the country, we urge you to take steps to ensure that Hadiya is not forcibly confined in the home of her natal family, denied the right to cohabit with her husband, and be subjected to coercion for exercising opting for faith of her choice", the letter to the Chief Minister read.
In it's preliminary report, NIA said that the case did not appear to be an isolated one and that it found a pattern in some other cases too and also hinted at the involvement of anti-national elements.
The High Court annulled the marriage. The Commission and the government should also immediately ensure that friends and well wishers are allowed to meet Hadiya and that she is allowed access to a phone and communication beyond the walls of her parental home, they said.
