Constitutional Glossary

Article 12 defines "the State" for the purposes of Part III (Fundamental Rights). It includes the Government and Parliament of India, the Government and Legislature of each State, all local authorities (such as municipalities and panchayats), and other authorities within the territory of India or under the control of the Government.

Through judicial interpretations, bodies that are instrumentalities or agencies of the government—even statutory corporations or government-controlled public companies—fall within this definition.

"Equality before the law" is a negative concept borrowed from English common law: no individual or official possesses special immunity or privilege above ordinary legal statutes.

"Equal protection of the laws" is a positive concept derived from the US 14th Amendment: equals must be treated equally, which permits the State to enact reasonable classifications and affirmative measures to uplift disadvantaged groups.

Article 14 forbids class legislation (arbitrary discrimination), but permits reasonable classification. To be valid, a classification must satisfy two tests: (1) it must be founded on an intelligible differentia distinguishing persons grouped together from those left out; and (2) that differentia must have a rational relation to the object sought to be achieved by the statute.

The Constitution intentionally left "untouchability" in quotation marks without an exhaustive statutory definition to encompass every historical and social manifestation of caste-based exclusion.

Unlike most other rights that operate only against the State, Article 17 is self-executing against private citizens and organisations, and enforcing any caste disability is punishable under the Protection of Civil Rights Act, 1955.

The six democratic freedoms guaranteed by Article 19(1) are not absolute licences. Clauses (2) through (6) empower the State to impose "reasonable restrictions" by law.

Restrictions can only be imposed on the specific grounds enumerated in the Constitution (such as sovereignty and integrity of India, public order, decency, morality, or security of the State) and must satisfy judicial proportionality tests.

The Constituent Assembly chose the Japanese/English phrase "procedure established by law" instead of the American "due process of law" to avoid judicial second-guessing of socio-economic legislation.

However, since the landmark Maneka Gandhi judgment (1978), the Supreme Court interpreted Article 21 to mean that any procedure depriving someone of life or personal liberty must not be arbitrary, oppressive, or fanciful; it must be just, fair, and reasonable.

Article 20(2) incorporates the ancient common law maxim *nemo debet bis vexari*. For the protection to apply, there must have been both a prior prosecution before a court of law or judicial tribunal AND a punishment inflicted.

Departmental inquiries or administrative actions do not constitute prosecution for the purpose of Article 20(2).

Article 20(3) protects an accused individual from compulsory testimonial self-incrimination. It applies from the formal accusation stage through court trial.

While compulsory confessions, narco-analysis, and polygraph tests without voluntary consent violate Article 20(3), taking physical samples (such as fingerprints, handwriting exemplars, or blood samples) under lawful statutory authority is generally permissible.

Unlike punitive detention (punishing a person after trial for a crime committed), preventive detention aims to intercept a person before an act threatening state security, public order, or essential supplies is carried out.

Article 22 provides vital safeguards: grounds of detention must be communicated promptly, representation must be facilitated, and detention exceeding three months requires scrutiny by an independent Advisory Board composed of High Court judges.

"Begar" refers to involuntary work extracted without payment, common in pre-independence zamindari and princely systems. Article 23 comprehensively prohibits human trafficking, begar, and bonded labour.

The Supreme Court has clarified that paying less than statutory minimum wages constitutes "forced labour" because economic destitution deprives the worker of genuine bargaining choice.

The Constitution empowers the higher judiciary to issue five ancient writs:

1. Habeas Corpus ("produce the body"): orders release of a person unlawfully detained.

2. Mandamus ("we command"): orders a public official or authority to perform a mandatory statutory duty.

3. Prohibition: directs a subordinate tribunal or court to cease proceedings exceeding its jurisdiction.

4. Certiorari ("to be certified"): quashes an order passed without jurisdiction or in violation of natural justice.

5. Quo Warranto ("by what authority"): inquires into the legality of a person holding an independent public office.

Articulated in the historic 1973 *Kesavananda Bharati* ruling, the Basic Structure doctrine holds that while Parliament has wide amending powers under Article 368, it does not possess constituent power to alter or destroy the core pillars of the Constitution.

Recognised basic structure features include: supremacy of the Constitution, republican and democratic form of government, secular character, separation of powers, federalism, judicial review, and the dignity and freedom of the individual.
