Article 20
Fundamental Right — Citizen Shield
Part III
Article 20 is the citizen's unbreakable shield against police coercion and retroactive state tyranny. Along with Article 21, it is so sacred that under the 44th Constitutional Amendment (Article 359), it CANNOT be suspended even during wartime or a National Emergency. It consists of three distinct constitutional pillars:
1. Article 20(1) — Protection against Ex-Post Facto Criminal Laws: No person can be convicted of an act that was not a crime at the time it was committed, nor can they be subjected to a penalty greater than what was prescribed when the act took place.
2. Article 20(2) — Protection against Double Jeopardy (Nemo debet bis vexari): No person shall be prosecuted and punished for the same offence more than once by a court of law.
3. Article 20(3) — Immunity from Self-Incrimination: 'No person accused of any offence shall be compelled to be a witness against himself.' This makes police torture, forced signatures on blank papers, and involuntary narco-analysis or polygraph tests completely unconstitutional.
Article 21
Fundamental Right — Citizen Shield
Part III
Article 21 contains just 18 words—'No person shall be deprived of his life or personal liberty except according to procedure established by law'—yet it has grown into the grandest human rights charter in the democratic world. Notably, it uses the word 'person', protecting both Indian citizens and foreign nationals.
In the watershed Maneka Gandhi v. Union of India (1978) verdict, the Supreme Court buried the narrow colonial view of A.K. Gopalan (1950) and forged the 'Golden Triangle' (Articles 14, 19, and 21). The Court ruled that 'Life' does not mean mere animal existence or breathing—it means living with full Human Dignity. Furthermore, the 'procedure established by law' cannot be any arbitrary statute; the law itself must be 'Just, Fair, and Reasonable' (Substantive Due Process).
Through creative judicial interpretation, the Supreme Court has read over 35 implied Fundamental Rights into Article 21—including the Fundamental Right to Privacy (Puttaswamy, 2017), Right to Emergency Medical Care (Parmanand Katara, 1989), Right to Livelihood and Shelter (Olga Tellis, 1985), Right to Clean Air and Water (Subhash Kumar, 1991), Right to Speedy Trial and Free Legal Aid (Hussainara Khatoon, 1979), Protection against Solitary Confinement and Handcuffing (Prem Shankar Shukla, 1980), and Right to Die with Dignity / Passive Euthanasia & Living Wills (Common Cause, 2018).
Article 47 places an unequivocal constitutional duty on the State: raising the level of nutrition and the standard of living of its people and the improvement of public health are among its 'primary duties'. It also directs the State to bring about prohibition of the consumption (except for medicinal purposes) of intoxicating drinks and drugs injurious to health. Combined with Article 21, the Supreme Court has used Article 47 to make emergency medical care, clean drinking water, Mid-Day Meals, ICDS Anganwadi nutrition, and food safety enforcement fundamental obligations of the government.
Article 83 governs 'Duration of Houses of Parliament' in Part V, Chapter II (Parliament). It lays down the constitutional rulebook for how Lok Sabha and Rajya Sabha are constituted, how presiding officers (Speaker/Chairman) function, member qualifications/disqualifications, quorum, passage of ordinary and financial Bills, budget grants, and parliamentary privileges. Specifically: (1) The Council of States shall not be subject to dissolution, but as nearly as possible one-third of the members thereof shall retire as soon as may be on the expiration of every second year in accordance with the provisions made in that...
Article 172 ('Duration of State Legislatures') in Part VI, Chapter III governs the State Legislature (Vidhan Sabha and, where applicable, Vidhan Parishad).

Specifically: (1) Every Legislative Assembly of every State, unless sooner dissolved, shall continue for five years from the date appointed for its first meeting and no longer and the expiration of the said period of 1 [five years] shall operate as a...
Article 250 ('Power of Parliament to legislate with respect to any matter in the State List if a Proclamation of Emergency is in operation') in Part XI (Relations between the Union and the States) structures Indian federalism. It governs territorial and subject-matter jurisdiction under the Union, State, and Concurrent Lists of the Seventh Schedule, GST concurrent powers (Art 246A), residuary powers (Art 248), inconsistency/repugnancy rules (Art 254), inter-state river water disputes (Art 262), or the Inter-State Council (Art 263). Specifically: (1) Notwithstanding anything in this Chapter, Parliament shall, while a Proclamation of Emergency is in operation, have power to make laws for the whole or any part of the territory of India with respect to any of the matters enumerated in...
Article 352 governs National Emergencies. Following lessons from the 1975–1977 Emergency, the 44th Constitutional Amendment (1978) introduced ironclad safeguards: an emergency can only be proclaimed on the written advice of the entire Union Cabinet (not the Prime Minister alone), the vague ground of 'internal disturbance' was replaced with 'armed rebellion', and the proclamation must be approved by a two-thirds special majority in both Houses of Parliament within one month.
Article 353 ('Effect of Proclamation of Emergency') in Part XVIII (Emergency Provisions, Articles 352–360) regulates extraordinary crisis powers—National Emergency (Arts 352–354), Union duty to protect States (Art 355), State constitutional breakdown / President's Rule (Arts 356–357), effect on Fundamental Rights (Arts 358–359), and Financial Emergency (Art 360). Crucially, after the 44th Amendment (1978), Articles 20 and 21 (Right to Life, Personal Liberty, and Fair Trial) can NEVER be suspended even during a National Emergency.

Crucially, after the 44th Amendment (1978), Articles 20 and 21 (Right to Life, Personal Liberty, and Fair Trial) can NEVER be suspended even during a National Emergency.
Article 355 ('Duty of the Union to protect States against external aggression and internal disturbance') in Part XVIII (Emergency Provisions, Articles 352–360) regulates extraordinary crisis powers—National Emergency (Arts 352–354), Union duty to protect States (Art 355), State constitutional breakdown / President's Rule (Arts 356–357), effect on Fundamental Rights (Arts 358–359), and Financial Emergency (Art 360).

Article 356 permits the President to dismiss a State Government and assume state executive powers upon a report from the Governor or otherwise, if governance cannot be carried on in accordance with the Constitution. Historically misused by ruling central parties to topple opposition state governments, the landmark 9-judge Supreme Court ruling in S.R. Bommai (1994) transformed Article 356 into a strictly regulated safety valve: the floor of the Assembly is the only place to test majority, and any arbitrary dismissal is subject to judicial review and restoration of the dissolved assembly.
Article 357 ('Exercise of legislative powers under Proclamation issued under article 356') in Part XVIII (Emergency Provisions, Articles 352–360) regulates extraordinary crisis powers—National Emergency (Arts 352–354), Union duty to protect States (Art 355), State constitutional breakdown / President's Rule (Arts 356–357), effect on Fundamental Rights (Arts 358–359), and Financial Emergency (Art 360).

Article 358 ('Suspension of provisions of article 19 during emergencies') in Part XVIII (Emergency Provisions, Articles 352–360) regulates extraordinary crisis powers—National Emergency (Arts 352–354), Union duty to protect States (Art 355), State constitutional breakdown / President's Rule (Arts 356–357), effect on Fundamental Rights (Arts 358–359), and Financial Emergency (Art 360). Crucially, after the 44th Amendment (1978), Articles 20 and 21 (Right to Life, Personal Liberty, and Fair Trial) can NEVER be suspended even during a National Emergency.
Article 359 ('Suspension of the enforcement of the rights conferred by Part III during emergencies') in Part XVIII (Emergency Provisions, Articles 352–360) regulates extraordinary crisis powers—National Emergency (Arts 352–354), Union duty to protect States (Art 355), State constitutional breakdown / President's Rule (Arts 356–357), effect on Fundamental Rights (Arts 358–359), and Financial Emergency (Art 360).

Article 366 ('Definitions') in Part XIX (Miscellaneous, Articles 361–367) covers vital structural rules: official functional immunity of the President and Governors while allowing citizens to sue the Government of India or State Government directly (Art 361), press freedom to publish true reports of Parliamentary and Assembly proceedings (Art 361A), anti-defection bar on remunerative political posts (Art 361B), abolition of privy purses of former princely rulers (Art 363A), and master constitutional definitions (Arts 366–367). Specifically: In this Constitution, unless the context otherwise requires, the following expressions have the meanings hereby respectively assigned to them, that is to say — (1) “agricultural income” means agricultural income as defined for the...
