Fundamental Rights (Part III — Articles 12–35)

These are justiciable — courts can enforce them. Can be suspended during Emergency (except Arts 20, 21).

Article 14 — Equality Before Law

No person shall be denied equality before law or equal protection of laws

Most expansive FR after Maneka Gandhi case (1978)
Includes: right to privacy (Puttaswamy, 2017), livelihood, health, education, speedy trial, dignity, environment

Article 32 — Right to Constitutional Remedies ("Heart and Soul")

Five writs:

Habeas Corpus — Produce the body (unlawful detention)
Mandamus — Command a public body to perform its duty
Prohibition — Stop inferior court from exceeding jurisdiction
Certiorari — Quash order of inferior court
Quo Warranto — By what authority do you hold this office?

Directive Principles (Part IV — Articles 36–51)

Non-justiciable but fundamental to governance. Courts cannot enforce them, but Parliament and States must keep them in mind when making law.

Key DPSPs:

Art 38: State to secure social order for welfare
Art 39: Equal pay for equal work, equal access to means of livelihood
Art 39A: Free legal aid (implemented via Legal Services Authorities Act)
Art 44: Uniform Civil Code (UCC) — still a directive, not implemented
Art 45: Free and compulsory education for children (now FR under Art 21A)
Art 48A: Protect and improve environment and safeguard forests/wildlife

Fundamental Duties (Part IVA — Article 51A)

Added by 42nd Amendment 1976 (Swaran Singh Committee). Originally 10, now 11 duties (added by 86th Amendment 2002).

Key duties: Respect Constitution/National Flag/Anthem, defend the country, promote harmony, preserve culture, protect environment, develop scientific temper, safeguard public property, strive for excellence.


Constitutional Amendments — Article 368

Simple majority (ordinary bills): matters under Art 5, 169, etc.

Special majority (2/3 of members present + voting AND majority of total strength): most amendments

Special majority + State ratification (½ of State legislatures): federal provisions — Lists, election of President, SC/HC jurisdiction

Basic Structure (Kesavananda Bharati, 1973): Parliament cannot destroy the basic structure even via Art 368. Includes: Supremacy of Constitution, Rule of Law, Judicial Review, Secularism, Federalism, Free Elections.

Practice Questions

Q1. Which Article provides the right to move Supreme Court for enforcement of Fundamental Rights?

A: Article 32 (Dr Ambedkar called it the "heart and soul" of the Constitution)

Q2. What is the Basic Structure Doctrine?

A: Laid down in Kesavananda Bharati v. State of Kerala (1973) — certain features of the Constitution (judicial review, separation of powers, federalism, secularism, democracy) cannot be amended even by Parliament under Article 368.

Q3. DPSP vs Fundamental Rights — which prevails?

A: FRs are justiciable and generally prevail, but Minerva Mills (1980) held that both must be harmoniously construed. Art 31C gives some DPSPs a shield — laws implementing Arts 39(b)/(c) cannot be challenged under Arts 14/19.

Q4. What are the three lists and which prevails in case of conflict?

A: Union List > Concurrent List > State List in case of conflict. On Concurrent List, Union law prevails under Art 254 unless State law has Presidential assent.
