It is noteworthy that the Indian Constitution doesn't identify the right to privacy as a fundamental right of citizens.
The said right is a corollary of Articles 19 and 21, which deal with the rights to life and liberty.
Several cases in the past have upheld it as a fundamental right, while others haven't.
How did petitioners defend the right to privacy?
Activist Ancilla says, "India has a population of 1.34bn. If they lose their basic right to privacy, it will be a huge setback for the world."
Petitioner Shyam Divan argued invasions of bodily integrity can only be allowed under a totalitarian regime.
In the absence of right to privacy in the digital age, any statute can be passed and citizens left helpless, he added.
Are their concerns valid?
Considering there have been several times when websites, including government portals, have leaked personal details of lakhs of Aadhaar holders due to "programming errors" or other reasons, Aadhaar does pose a risk to privacy if handled carelessly.
How did the government respond?
Appearing for Gujarat, advocate Rakesh Dwivedi asked that if US considered privacy as a fundamental right, "how could US forces invade privacy of a house to eliminate Laden?"
He agreed that privacy was intrinsic to other rights, but if it is, "where's the necessity of defining it as a standalone fundamental right?"
