Elimination traps

Constitutional vs statutory — Aadhaar is established under a statutory act, not the Constitution.

Body vs treaty — Distinguish between the various components of DPI (Aadhaar, UPI, DigiLocker etc.) and the overarching concept.

Treaty = agreement between states; body = institution.
