While The Supreme Court decides the validity of the Aadhaar, the Delhi High Court noted that the unique identification number or the voter ID card cannot be used as a proof of birth for a person. The court said that a birth certificate or a certificate provided by a school where a person has completed their education will be a “more robust evidence” of a person’s age. The observation was made when a plea for a kidney donation was rejected by an authorisation committee, citing age differences between the recipient and donor being contradictory on the Aadhaar card and the voter ID card.
