Are clerics making a mockery of Islamic law?

The All India Muslim Personal Law Board (AIMPLB) has made an astonishing claim as the Supreme Court is at the helm of hearing a batch of petitions challenging nikah halala. It stated that the practice "cannot be challenged since it is quranic".
Nikah-halala is a practice in which a divorced woman has to consummate the marriage with another man and then get a divorce from him before remarrying her previous husband.
