Revision summary
A nine-judge Bench in Puttaswamy (2017) held privacy to be a fundamental right. M.P. Sharma and Kharak Singh were overruled insofar as they denied privacy. Privacy covers space, personal data and intimate decisions, read through Articles 14, 19 and 21. Limits are law, legitimate aim and proportionality, not a blank cheque to the State. Part III is open-textured; privacy is an unenumerated right located in existing Articles.

Copper italics in this answer — like this — are the key facts. Each one is unpacked in the Facts & figures rail.
Introduction
On 24 August 2017 a nine-judge Bench in Justice K.S. Puttaswamy v. Union of India held that the right to privacy is a fundamental right. That judgment is the latest and controlling reading of how far Part III reaches. Scope here means whose liberty is protected, against whom, and with what limits. Privacy does not add a new numbered Article; it thickens Articles 14, 19 and 21, and the liberty cluster around them.
Body
What the Puttaswamy Bench held
- Privacy is intrinsic to life and personal liberty under Article 21 and to the freedoms and equality that make a person a constitutional subject, not a data point of the State.
- Earlier contrary observations in M.P. Sharma (1954) and Kharak Singh (1962), so far as they denied a right to privacy, were overruled.
- Privacy has at least three aspects: spatial privacy (a private space), informational privacy (control over personal data), and decisional autonomy (intimate choices of family, faith, food and orientation).
- The right is not absolute. A restriction must rest on law, serve a legitimate State aim, and be proportionate — suitable, necessary, and balanced against the right.
- Dignity, ordered liberty and the idea of a constitutional republic of individuals, not only of majorities, were the moral grounds of the holding.
How the judgment widens the scope of Fundamental Rights
- Unenumerated rights: Part III is not a closed list of named heads. If a claim is part of dignity and liberty, the Court may locate it inside existing Articles, as it did earlier for travel, livelihood and legal aid, and now for privacy.
- Horizontal shadows: the primary duty is still on the State (Article 12). Yet informational privacy implies that the State must also regulate private databases, because a fundamental right that stops at the police station but dies at a private server is hollow.
- Equality and freedom travel together: a privacy holding under Article 21 is read with Article 14 against arbitrary profiling and with Article 19 against a chill on speech, association and movement.
- Later use of the same cluster — for example on sexual orientation, adultery law, and data protection debates — shows that Puttaswamy is a gateway judgment, not a one-case rule about Aadhaar alone.
- Reasonable restrictions remain. National security, crime investigation, and taxation can still enter private life if they pass the proportionality test. Scope expanded; State power was not abolished.
What the scope still does not cover
- Privacy is not a veto on every welfare database or every criminal search. The Bench asked for justification, not for a vacuum of governance.
- Economic and social rights in Part IV do not become justiciable merely because privacy is fundamental; budgets and statutes still do that work.
- Group claims (caste, language, religion) remain in their own Articles; privacy is primarily a personal liberty tool, though it can protect a stigmatised group’s intimate life.
- Parliamentary competence to make a data-protection statute is affirmed in spirit: a fundamental right often needs a detailed law to be usable against both the State and the market.
Examine, do not inflate
- The latest judgment enlarges the living content of Part III without rewriting the text.
- The real scope test is future proportionality: surveillance, Aadhaar-like seeding, and commercial profiling will show whether privacy is a right or a recital.

Conclusion
Puttaswamy places privacy inside Articles 14, 19 and 21 as spatial, informational and decisional liberty, and it overrules the old denials of that right. Fundamental Rights therefore reach intimate choice and personal data, subject to a law that is legitimate and proportionate. The scope of Part III grew; it did not become unlimited.

-
Is privacy now a separate Article in Part III?
No. The Court located it inside existing Articles, mainly 21 with 14 and 19. The text was not amended; the scope was.
-
Can the State still collect Aadhaar or crime data?
Yes, if a law authorises it, the aim is legitimate, and the design is proportionate. Puttaswamy requires justification, not a ban on every database.

"China's Belt and Road Initiative (BRI) has transformed South Asia from a regional space into a theatre of great power competition." Analyse the strategic implications of the BRI for India's security and regional influence in South Asia.
India and its Neighbourhood
China's Belt and Road Initiative has turned South Asia into a zone of great-power rivalry, not just a regional neighbourhood. Ports like Gwadar and Hambantota raise fears of maritime encirclement and pressure on Indian Ocean trade routes. CPEC through Pakistan-Occupied Kashmir directly challenges India's sovereignty and adds a two-front security worry. Debt-heavy Chinese projects in Sri Lanka and Maldives have pushed smaller neighbours to hedge between Beijing and New Delhi. India must respond with trusted connectivity—Chabahar, BIMSTEC, Neighbourhood First aid, and Indo-Pacific partnerships—so development does not come with strategic dependence on China.

"Energy security constitutes the dominant kingpin of India's foreign policy, and is linked with India's overarching influence in Middle Eastern countries." How would you integrate energy security with India's foreign policy trajectories in the coming years?
India and its Neighbourhood
Imported crude and LNG make energy the hard core of India’s Middle East policy, alongside diaspora and ports. UAE CEPA, I2U2, IMEC and Chabahar are the diplomatic frame around tankers. Risks: Hormuz, Red Sea, Iran sanctions, OPEC+ and over-reliance on any one discount supplier. Future integration: diversified barrels and routes, Gulf green-hydrogen partnerships, naval sea-lane policy, multi-alignment among regional rivals. The kingpin should shrink as the energy mix greener; it cannot be wished away this decade.

India-Africa digital partnership is achieving mutual respect, co-development and long-term institutional partnerships. Elaborate.
India and its Neighbourhood
The partnership runs on Pan-African e-Network heritage, ITEC training, IAFS, and newer DPI (payments, identity, document rails). Co-development means African adaptation and AU working groups, not a vendor dump. Respect means data under African law, unlike a back-doored hardware grid. Limits: power and connectivity, summit-without-follow-through, and China’s larger cable footprint. Score the relationship by live hospital and payment links.
