New Delhi: The Supreme Court on Friday made the Reserve Bank of India (RBI) a party in a plea challenging the validity of the Aadhaar scheme through which the government intends to issue a unique identity number to all residents in the country.

Petitioner Mathew Thomas had claimed the central bank was asking for the Aadhaar number to open bank accounts and know-your-customer documents.

A bench headed by chief justice H.L. Dattu said the case will be heard by a bench constituted by him as the issue of Aadhaar was important.

The public interest litigant had relied on an earlier interim order of the apex court, which had said that the Aadhaar number could not be a mandatory requirement in availing of services.
