The law's own dictionary

Words the Constitution defines itself, plus the courtroom vocabulary every citizen bumps into — writs, doctrines, FIRs and the rest.

Concepts & doctrines

Anticipatory Bail: A pre-arrest legal remedy allowing a person who fears arrest on accusation of a non-bailable offence to seek bail in advance from a Sessions Court or High Court. If granted, the person is released on bail immediately upon arrest, subject to conditions imposed by the court.; See BNSS Section 482
Article 14 – Right to Equality: This article guarantees equality before the law and equal protection of the laws to all persons within India's territory. Courts use the 'reasonable classification' test to determine whether differential treatment under a law is constitutionally permissible.; See Article 14
Article 141 – Binding Precedent: This article provides that the law declared by the Supreme Court is binding on all courts within the territory of India. It establishes the doctrine of precedent as a constitutional command rather than mere judicial convention.; See Article 141
Article 142 – Complete Justice: This article empowers the Supreme Court to pass any order necessary to do 'complete justice' in a matter pending before it, even if not strictly provided for by existing law. It has been used for remedies ranging from environmental protection to resolving deadlocks in high-profile disputes.; See Article 142
Article 19 – Freedom of Speech and Expression: This article guarantees six fundamental freedoms to citizens, including speech and expression, assembly, association, movement, residence, and profession, subject to reasonable restrictions specified in the Constitution. These restrictions include grounds like public order, morality, and sovereignty of India.; See Article 19
Article 20 – Protection in Respect of Conviction for Offences: This article provides three protections to accused persons: no conviction except for violation of a law in force at the time of the act (no ex post facto punishment), no double jeopardy for the same offence, and no compulsion to be a witness against oneself. These safeguards apply regardless of citizenship.; See Article 20
Article 21 – Right to Life and Personal Liberty: This article guarantees that no person shall be deprived of life or personal liberty except according to a fair, just, and reasonable procedure established by law. Judicial interpretation has expanded it to include rights like privacy, dignity, livelihood, and a clean environment.; See Article 21
Article 226 – High Court Writ Jurisdiction: This article empowers High Courts to issue writs not only for enforcement of fundamental rights but also for 'any other purpose,' giving them wider writ jurisdiction than the Supreme Court under Article 32. This makes High Courts an important first forum for constitutional remedies.; See Article 226
Article 32 – Right to Constitutional Remedies: This article empowers individuals to directly approach the Supreme Court for enforcement of fundamental rights through writs. Dr. B.R. Ambedkar called it the 'heart and soul' of the Constitution.; See Article 32
Article 356 – President's Rule: This article allows the President to assume control of a state's administration if satisfied that the state government cannot function according to constitutional provisions, based on a report from the Governor or otherwise. Its use is subject to judicial review, as established in S.R. Bommai v. Union of India (1994).; See Article 356
Bail: The conditional release of an accused person from custody, typically on furnishing a bond, pending investigation or trial. Indian law distinguishes bailable offences (where bail is a right) from non-bailable offences (where it is at court discretion).
Basic Structure Doctrine: A judicially evolved principle holding that Parliament's power to amend the Constitution under Article 368 cannot alter its 'basic structure'—core features like democracy, secularism, judicial review, and federalism. It was established in Kesavananda Bharati v. State of Kerala (1973).; See Article 368
Certiorari: A writ by which a higher court quashes an order or decision of a lower court, tribunal, or quasi-judicial authority for lack of jurisdiction, error of law, or violation of natural justice. It is a corrective, after-the-fact remedy.
Chargesheet (Police Report): The final report filed by police before a magistrate after completing investigation, summarising evidence and naming the accused to be tried. It signals the transition from investigation to the judicial trial process.; See BNSS Section 193
Cognizable Offence: A category of offence, generally serious in nature, for which police can arrest without a warrant and start investigation without prior court permission. Murder and robbery are typical examples, in contrast to non-cognizable offences requiring court authorisation.
Collegium System: A judicially evolved practice under which appointments and transfers of judges to the Supreme Court and High Courts are decided by a panel of senior judges rather than solely by the executive. It emerged from a series of Supreme Court judgments interpreting the consultation process for judicial appointments.
Colourable Legislation: A doctrine that examines whether a legislature has enacted a law on a subject outside its constitutional competence but disguised it as one within its power. Courts look at the true substance and effect of the law, not merely its stated form.; See Article 246
Compoundable Offence: An offence where the complainant and accused can settle the matter privately, leading to withdrawal of criminal charges, either with or without the court's permission depending on the offence's severity. Not all offences are compoundable; serious crimes like murder cannot be settled this way.
Contempt of Court: An act of disobedience or disrespect toward a court, or conduct that obstructs the administration of justice, punishable by the court itself. It can be civil (wilful disobedience of a court order) or criminal (scandalising the court or interfering with judicial proceedings).
Curative Petition: A final safeguard allowing the Supreme Court to reconsider its own judgment even after a review petition has been dismissed, to prevent abuse of process or gross miscarriage of justice. It was recognised in Rupa Ashok Hurra v. Ashok Hurra (2002) and is decided by senior judges in chambers.; See Article 137
Doctrine of Eclipse: A principle stating that a pre-Constitution law inconsistent with fundamental rights is not void ab initio but becomes unenforceable ('eclipsed') only against citizens for the affected rights. It revives if the conflicting fundamental right is later amended or removed.; See Article 13
Doctrine of Pith and Substance: A principle used to determine the true nature ('pith and substance') of a law when it appears to overlap between Union and State legislative lists. If the law is substantially within the enacting legislature's competence, incidental encroachment on the other list does not invalidate it.; See Article 246
Doctrine of Proportionality: An administrative and constitutional law principle requiring that the severity of a restriction or penalty must be proportionate to the object it seeks to achieve. Courts use it to review whether state action, especially restrictions on fundamental rights, is excessive relative to its purpose.
Doctrine of Repugnancy: This doctrine applies when a State law conflicts with a Union law on a subject in the Concurrent List; the Union law generally prevails and the State law becomes void to the extent of the conflict. An exception exists if the State law has received the President's assent.; See Article 254
Doctrine of Severability: This doctrine holds that if part of a statute is unconstitutional, only that offending part is struck down while the rest of the law remains valid, provided the valid portion can stand independently. If the valid and invalid parts are inseparable, the entire law falls.; See Article 13
Doctrine of Ultra Vires: A principle used to invalidate an action, rule, or law that exceeds the legal authority granted to the body that made it. It applies both to delegated legislation exceeding statutory authority and to legislative acts exceeding constitutional limits.
Double Jeopardy: A constitutional protection preventing a person from being prosecuted and punished more than once for the same offence based on the same facts. It does not bar separate proceedings for distinct offences arising from the same act.; See Article 20
First Information Report (FIR): The written document prepared by police upon receiving information about the commission of a cognizable offence, marking the formal start of a criminal investigation. It is not evidence in itself but sets the investigative process in motion.; See BNSS Section 173
Golden Triangle: A term describing the interconnected fundamental rights under Articles 14 (equality), 19 (freedoms), and 21 (life and liberty), which courts read together to test the validity of state action. Any law affecting personal liberty must satisfy all three articles.
Habeas Corpus: A writ that orders a person (often a jailer or state authority) to produce a detained individual before the court and justify the detention. It safeguards personal liberty against illegal or arbitrary confinement, whether by the state or a private person.
Harmonious Construction: A rule of interpretation requiring that when two provisions of a statute or the Constitution appear to conflict, courts should read them together so both can operate without one nullifying the other. It avoids treating any provision as redundant.
Judicial Activism: A term describing courts taking a proactive role in protecting rights and addressing governance gaps, often through expansive interpretation of constitutional provisions or PILs. It is sometimes contrasted with 'judicial restraint,' where courts defer more to legislative and executive judgment.
Judicial Review: The power of courts to examine the constitutionality of legislative enactments and executive actions and to strike them down if they violate the Constitution. It is considered part of the basic structure of the Indian Constitution.; See Article 13
Mandamus: A writ commanding a public official, body, or lower court to perform a duty it is legally obligated to perform but has failed or refused to do. It cannot be used to compel discretionary or purely private acts.
Money Bill: A bill dealing exclusively with matters like taxation, government borrowing, or expenditure from the Consolidated Fund, as defined by the Constitution. It can only be introduced in the Lok Sabha, and the Rajya Sabha's role is limited to recommending changes, not blocking it.; See Article 110
Ordinance: A law promulgated by the President (at the Union level) or Governor (at the state level) when the legislature is not in session and immediate action is needed. It has the same force as an Act of the legislature but must be approved within a specified period after the legislature reconvenes, or it lapses.
Plea Bargaining: A pre-trial process allowing an accused to negotiate with the prosecution, typically pleading guilty to a lesser charge or accepting a reduced sentence in exchange for a quicker resolution. It is available only for certain categories of offences and is not permitted in serious crimes affecting the socio-economic condition of the country or against women and children.
Police Remand/Custody: The period during which an arrested person may be held in police custody or judicial custody for further investigation, ordered by a magistrate. Total detention before filing of a chargesheet is subject to statutory time limits depending on the severity of the offence.; See BNSS Section 187
Preventive Detention: The detention of a person without trial to prevent them from committing a future offence, rather than punishing a past one. Article 22 provides specific procedural safeguards for such detention, including limits on detention periods and rights to representation before an advisory board.; See Article 22
Prohibition: A writ issued to stop a lower court or tribunal from continuing proceedings that exceed its jurisdiction or violate legal limits. Unlike certiorari, it is preventive rather than corrective, issued before the decision is finalised.
Public Interest Litigation (PIL): A judicial mechanism allowing any public-spirited person or organisation to approach the court on behalf of those unable to do so themselves, typically to enforce fundamental rights or address issues of public concern. It relaxed the traditional rule of standing (locus standi) in Indian constitutional litigation.
Quo Warranto: A writ questioning the legal authority of a person to hold a public office, asking 'by what warrant' they occupy it. If the holder lacks proper qualification or authority, the court can restrain them from acting in that office.
Rule of Law: A foundational constitutional principle meaning that all persons, including the government, are subject to and accountable under the law, and no one is above it. It implies supremacy of law, equality before law, and predictability in legal processes.
Self-Incrimination: A constitutional protection giving an accused person the right not to be compelled to be a witness against themselves in a criminal case. This underlies the accused's right to remain silent during interrogation and trial.; See Article 20
Separation of Powers: A constitutional principle dividing governmental functions among the legislature, executive, and judiciary to prevent concentration of power in one body. In India this separation is not rigid but built into checks and balances, and it is considered part of the basic structure.
Zero FIR: An FIR that can be registered at any police station regardless of where the offence occurred or which station has territorial jurisdiction. It is later transferred to the police station with proper jurisdiction, ensuring victims are not turned away on technical grounds.; See BNSS Section 173
