The Centre's affidavit filed in the top court said that the 2019 Act helps in ensuring the larger constitutional goals of gender justice and gender equality of married Muslim women.
The accused's wife Farida Bano filed an FIR against her husband Rehman last month, accusing him dowry harassment and divorcing her through triple talaq.
Sataniya allegedly sent his wife three letters by post on February 28, April 2 and May 8 to give triple talaq, an official said, adding that these letters were produced before the police.
