The court has already issued notices to the Centre regarding the matter.
Nikah-Halala is a practice intended to curb the incidence of divorce. Under it, a man cannot remarry his former wife unless she marries another man, consummates the marriage, gets a divorce and observes a period of separation period called "Iddat". Polygamy is the practice of having more than one wife at a time.
The need to stop Nikah Halala and polygamy has been highlighted repeatedly by women's groups, which contend that the practices are discriminatory and denigrating for women. The petitioners -- two Muslim women and a BJP lawyer -- want the top court to declare both practices illegal and unconstitutional.
In her petition, one of the women said she has been a victim of polygamy and had filed the petition to highlight the plight of thousands of Muslim women across the country. BJP lawyer Ashwini Kumar Upadhyay said a ban on polygamy and Nikah-Halala is the need of the hour to secure basic rights.
In its judgment, delivered in August, the top court called instant Triple Talaq "bad in law". It is also "not integral to religious practice and violates constitutional morality," the court said.
Later, the government drafted a new law against Triple talaq, calling it unconstitutional, and derogatory and discriminatory for women. The bill, which proposes a three-year-jail term for a Muslim man who divorces his wife instantly by uttering triple talaq thrice, has been passed in Lok Sabha and is now pending in Rajya Sabha.
