In an emphatic dissent from the majority, Justice Chandrachud has held the entire Aadhar project to be unconstitutional.

The very act of passing the Aadhaar Act 2016 as a money bill was held to be unconstitutional by Justice Chandrachud, dissenting from the majority view expressed through Justice Sikri's judgment that there was no impropriety in introducing it as money bill.

"The passing Aadhaar Act as money bill is a fraud on the constitution", Justice Chandrachud observed. The decision of Speaker to classify a bill as money bill is amenable to judicial review. The judgment also highlighted the importance of Rajya Sabha in passing laws.

"If a constitution has to survive political aggrandizement, notions of power and authority must give compliance to rule of law.", he observed in his dissenting judgment.
