Aadhaar Case

The Supreme Court's decision on the world's largest biometric ID system.

🎯 Learning Objectives

  • ▸ Understand the Aadhaar architecture
  • ▸ Analyze the Court's reasoning in upholding Aadhaar
  • ▸ Understand why Section 57 was struck down

The Balance

The Court had to balance the privacy rights of citizens with the government's interest in providing subsidies and preventing fraud. The Court held that Aadhaar does not violate privacy because it collects minimal biometric data and the benefits outweigh the risks.

Striking Down Section 57

Section 57 of the Aadhaar Act allowed private companies to use Aadhaar for authentication. The Court struck this down, holding that it was unconstitutional because it could lead to mass surveillance by private entities.

💡 Example

Before the judgment, you had to link Aadhaar to get a SIM card. After the judgment, this requirement was struck down, restoring privacy for mobile users.
