The board told a five-judge constitution bench headed by Chief Justice J S Khehar, which was hearing pleas challenging the constitutional validity of triple talaq, that all patriarchal societies discriminate.
Sibal told a bench, also comprising Justices Justices Kurian Joseph, R F Nariman, U U Lalit and Abdul Nazeer, that there was a difference between personal law and customs and usage.
"All patriarchal societies are partial. In Hinduism, a father can will away his property to anyone, but not in the Muslim community. I can point out many such practices in the Hindu society. Is it better for a woman to apply for divorce and fight for 16 years and get nothing," Sibal said.
The arguments of AIMPLB remained inconslusive and will continue tomorrow.
During the hearing, Additional Solicitor General Tushar Mehta said that AIMPLB should apologise for justifying triple talaq in its affidavit by saying that men have greater strength to control their emotions.
