The Supreme Court of India has time and again restricted use of unique identification (UID) number or Aadhaar to public distribution system (PDS) Scheme, the liquefied petroleum gas (LPG) distribution scheme, the Mahatma Gandhi National Rural Employment Guarantee Scheme (MGNREGS), National Social Assistance Programme (Old Age Pensions, Widow Pensions, Disability Pensions), Prime Minister’s Jan Dhan Yojana (PMJDY) and Employees’ Provident Fund Organisation (EPFO). The Supreme Court has repeatedly emphasised that the UID number where permitted “is purely voluntary and it cannot be made mandatory till the matter is finally decided by the Court one way or the other“
