The Supreme Court on Friday expressed anguish at a PIL seeking direction to the Centre to take steps and consider a new law to check religious conversions.

A bench headed by Justice R.F. Nariman said there is a reason why word propagate is there in the Constitution and there is no reason why persons above 18 cannot be allowed to choose their religion. Declining to entertain the PIL by advocate Ashwini Upadhyay, the bench said: "It is a publicity interest litigation."
