Delhi Police Defends Facial Recognition on Accuracy. Puttaswamy Asks About Authority First.
The Court's framing - testing "proportionality" - invokes the four-pronged standard from K.S. Puttaswamy vs Union of India (2017), which requires not just that a surveillance measure be effective and narrowly targeted, but that it rest on legislative backing in the first place; Delhi Police's affidavit defends FRS on accuracy and necessity but does not point to a specific statute authorising its use.
