New Delhi: The Supreme Court on Friday issued a notice on a petition challenging the Union ministry's notification for preparation of National Population Register (NPR). A bench headed by the Chief Justice of India said that the matter would be taken along with the batch of anti-CAA petitions on January 22.

It is pointed out in the petition that Citizenship (Registration of Citizens and Issue of National Identity Cards) Rules, 2003 give power to the local registrar to mark "doubtful citizens" from the NPR.
