The Supreme Court on Wednesday permitted an NGO to make Himachal Pradesh and Madhya Pradesh as parties to a pending petition challenging the controversial state laws regulating conversions due to inter-faith marriages.

A Bench headed by Chief Justice S.A.Bobde also allowed Muslim body Jamiat Ulama-I-Hind to become a party to the petition on the ground that a large number of Muslims are being harassed under these laws across the country.
