Privacy is a fundamental right: What will change now?

The ramifications of the verdict go much farther than Aadhaar. The SC linked the right to Articles 14, 19 and 21, thus extending it to sexuality, parting of personal data through credit cards/internet, etc.

Any law infringing on the Right to Privacy stands quashed, lawyer Prashant Bhushan says.

However, privacy hasn't been defined. Controversies will have to be dealt with on a case-to-case basis.

The Delhi HC in 2009 decriminalized homosexuality, but the SC later upheld Section 377, saying it affected a "minuscule fraction of the population".

Justice DY Chandrachud observed, "That 'a miniscule fraction' (is affected) is not a sustainable basis to deny the right to privacy."

Discrimination on the basis of sexual orientation is "deeply offensive", he added.

A petition against Section 377 is pending in the SC.

The MTP Act allows abortions up to 20 weeks, subject to certain terms. But Justice J Chelameswar noted: "A woman's choice of whether to bear a child or abort are areas which fall in the realm of privacy."

Dismissing a right just because it is not found in the Constitution's text "would be an affront…to the wisdom of the Constituent Assembly members", he said.

The beef ban has seen a raging debate. Several people have died in related violence.

Now things are likely to change. "I do not think that anybody would like to be told by the State as to what they should eat or how they should dress or whom they should be associated with either in their personal, social or political life," Justice Chelameshwar said.

Personal details about individuals often make their way out of the target audience. Under Section 66A, an individual can be prosecuted if their online posts don't meet certain criteria.

Private companies collect users' data on a regular basis to customize services.

The DNA Profiling Bill holds that someone's DNA can be profiled without consent.

All such practices and laws may have to be overhauled.
