Open almost any reported Indian judgment and you will meet a Latin maxim doing real work — not as ornament, but as the hinge on which the result turns. A maxim compresses a settled principle into a phrase the court can invoke without re-arguing it from first principles: actus non facit reum nisi mens sit rea decides whether a statutory offence needs a guilty mind, res ipsa loquitur shifts the burden in a negligence claim, audi alteram partem voids an order passed without a hearing. This article walks through the maxims that recur most often in Indian benches and shows, case by case, exactly how the Supreme Court has applied — and sometimes refused to apply — each one. For the underlying grammar of these phrases, start with our introduction to legal maxims and the Legal Maxims hub.
Why Maxims Still Decide Cases
A legal maxim is a condensed statement of a principle that has hardened into received wisdom. Indian courts use maxims for three reasons. First, economy: a phrase like ubi jus ibi remedium lets a bench invoke an entire doctrine of remedial law in three words. Second, continuity: because the Indian legal system inherited the common law, maxims provide a shared vocabulary linking modern judgments to centuries of precedent. Third, persuasion: a maxim carries rhetorical authority that a freshly minted formulation cannot.
But Indian courts have never treated maxims as binding rules in themselves. A maxim is, at most, a guide to the reasoning behind a rule; it is not the rule. The Supreme Court has repeatedly cautioned that a maxim must yield to the language of a statute and to the justice of the case. The maxim falsus in uno, falsus in omnibus, for instance, is followed in some common-law jurisdictions but expressly rejected in India. The lesson for the exam candidate is to know not only what a maxim means but precisely how — and whether — Indian benches actually apply it. The sections below take the maxims that recur most frequently and pin each to a verified holding.
Actus Non Facit Reum Nisi Mens Sit Rea — The Guilty Mind
“The act does not make a person guilty unless the mind is also guilty.” This is the foundational maxim of criminal liability, and Indian courts treat it as a presumption: every offence is presumed to require mens rea unless the statute, by clear language or necessary implication, excludes it. The leading authority on that exclusion is State of Maharashtra v. Mayer Hans George, AIR 1965 SC 722. George, a German national, flew from Zurich towards Manila carrying 34 kg of gold concealed in a specially tailored jacket; the aircraft halted at Bombay, where customs officers found the gold. He was prosecuted under the Foreign Exchange Regulation Act, 1947 for bringing gold into India without permission. His defence was that he had no knowledge of the Indian notification requiring a declaration — no guilty mind.
The Supreme Court, by majority, held the offence to be one of strict liability. Where a statute is enacted to safeguard the national economy and the public interest, the Court reasoned, the ordinary presumption of mens rea is displaced; the act of bringing in the gold was itself the offence, and intention was irrelevant. The case remains the textbook illustration that the maxim is a presumption, not an inflexible rule — regulatory and economic offences routinely rebut it. For the criminal-law cluster of maxims in full, see maxims relating to criminal law.
Audi Alteram Partem — Hear the Other Side
“Hear the other side.” No person may be condemned, penalised or deprived of a right without being given a fair opportunity to be heard. The maxim's modern Indian career was launched by Maneka Gandhi v. Union of India, AIR 1978 SC 597. The petitioner's passport was impounded “in the public interest” without any reason being communicated and without a hearing. The seven-judge bench held that the procedure established by law under Article 21 must be “right, just and fair” — and that fairness imports the rule of natural justice. Even where the statute is silent, the Court held, audi alteram partem is to be read into it; a hearing cannot be denied merely because the enabling provision does not mention one.
Maneka Gandhi did two things at once: it elevated procedural fairness to a constitutional command under Articles 14 and 21, and it confirmed that the absence of an express statutory hearing is no answer to a claim of natural justice. The maxim is not absolute — it bends to urgency, to legislative exclusion by clear words, and to situations where a hearing would serve no purpose — but the burden of justifying its exclusion lies firmly on the authority. The fuller treatment of this maxim and its companion sits in maxims relating to justice.
Nemo Judex in Causa Sua — The Rule Against Bias
“No one should be a judge in his own cause.” The second limb of natural justice forbids a decision-maker from adjudicating a matter in which he has a personal interest. The watershed Indian authority is A.K. Kraipak v. Union of India, AIR 1970 SC 150. A selection board constituted to recruit officers into the Indian Forest Service included, as a member, the Acting Chief Conservator of Forests — who was himself a candidate for selection. Although he abstained from the board's deliberations when his own name was considered, he sat and voted when the claims of his rivals were assessed, and he was present when the final order of preference was drawn up.
The Supreme Court set aside the selection. It held that actual bias need not be proved; a real likelihood or reasonable apprehension of bias is enough, because justice must not only be done but must manifestly be seen to be done. Kraipak is doubly important: it applied the bias rule to a selection that was, on its face, administrative rather than judicial, and in doing so it dissolved the old boundary between administrative and quasi-judicial functions for the purposes of natural justice. After Kraipak, any authority whose decision affects rights or legitimate interests must be free of bias.
Ubi Jus Ibi Remedium — Where There Is a Right, There Is a Remedy
“Where there is a right, there is a remedy.” The maxim traces to the English case Ashby v. White (1703), where a qualified voter wrongfully prevented from voting was held entitled to damages even though the candidate he favoured won — the violation of the legal right was itself actionable. Indian courts have given the maxim constitutional muscle. In Bhim Singh v. State of Jammu & Kashmir, AIR 1986 SC 494, an MLA was unlawfully arrested by police and deliberately prevented from attending a session of the Legislative Assembly, in breach of his constitutional and legal rights.
By the time the matter reached the Supreme Court he had already been released, so habeas corpus served no purpose. The Court held that mere release does not wash away the wrong: where a person's constitutional and legal rights are invaded with mischief or malice, the Court has jurisdiction to compensate the victim in money. It awarded Bhim Singh ₹50,000 as exemplary monetary compensation. The case is a leading illustration of the maxim translated into the constitutional remedy of compensation for established infringements of fundamental rights — a right without a remedy being, in the Court's view, no right at all.
Res Ipsa Loquitur — The Thing Speaks for Itself
“The thing speaks for itself.” In the law of negligence, the ordinary rule is that the plaintiff must prove the defendant's want of care. Res ipsa loquitur is an evidentiary aid that reverses this where the accident is of a kind that does not ordinarily happen without negligence and the instrumentality was under the defendant's control. The leading Indian application is Pushpabai Purshottam Udeshi v. Ranjit Ginning & Pressing Co., AIR 1977 SC 1735. A passenger died when the company car in which he was travelling, driven by the company's manager, left the road and struck a tree while travelling from Nagpur to Pandhurna. There was no eyewitness to the manner of driving.
The Supreme Court invoked res ipsa loquitur: a car driven with reasonable care does not, in the ordinary course, veer off and collide with a roadside tree with such violence. The very nature of the accident raised an inference of negligence, casting on the defendant the burden of explaining how it could have occurred without want of care — a burden it failed to discharge. The maxim thus operated to shift the evidentiary burden rather than to impose liability outright, a distinction Indian benches have been careful to preserve.
Qui Facit Per Alium Facit Per Se — Vicarious Liability
“He who acts through another does the act himself.” This maxim underpins the law of vicarious liability — a master is answerable for the torts of his servant committed in the course of employment. Its most significant Indian deployment concerned the State itself. In State of Rajasthan v. Vidhyawati, AIR 1962 SC 933, a government jeep, being driven back from the workshop by a State-employed driver, knocked down and fatally injured a pedestrian. The widow sued the State.
The Supreme Court held the State of Rajasthan vicariously liable for the negligent act of its servant committed in the course of employment, rejecting the argument that the State enjoyed a sweeping common-law immunity inherited from the days of the East India Company. The Court reasoned that in a modern welfare State, which undertakes a vast range of activities through its employees, there is no justification for exempting it from the ordinary liability of an employer for the torts of its servants. The driver acted for the State, and so the State was treated as having acted itself. The decision is a foundational authority on the tortious liability of the State and a direct application of the maxim to public employment.
Delegatus Non Potest Delegare — A Delegate Cannot Sub-Delegate
“A delegate cannot further delegate.” Where a statute confers a power on a named authority, that authority cannot, in the absence of express words or necessary implication, hand the power on to someone else. Indian courts treat the maxim as an interpretive presumption against sub-delegation. The point was decisively applied in A.K. Roy v. State of Punjab, (1986) 4 SCC 326 (AIR 1986 SC 2160). Section 20(1) of the Prevention of Food Adulteration Act, 1954 permitted a prosecution to be launched by the Central or State Government or by a person authorised in writing by them. The Food (Health) Authority of Punjab, itself an authorised person, purported to sub-delegate that power of consent to a Food Inspector, who then filed the complaint.
The Supreme Court quashed the prosecution. Section 20(1), it held, did not contemplate a further delegation by the person already authorised; the authorised authority could not, in turn, authorise another to give the written consent. The complaint by the Food Inspector under a sub-delegated authority was therefore incompetent. A.K. Roy is the standard citation for the proposition that delegated power cannot be sub-delegated unless the statute clearly permits it — a guardrail that Indian benches apply strictly in penal and regulatory contexts.
Res Judicata — A Decided Matter Stays Decided
“A matter already adjudged.” The doctrine of res judicata bars the re-litigation of an issue that has been finally decided between the same parties by a competent court. The question that troubled the early Constitution-era Supreme Court was whether the principle applied to constitutional writ petitions. Daryao v. State of Uttar Pradesh, AIR 1961 SC 1457, settled it. The petitioners, having had their writ petitions under Article 226 dismissed on merits by the High Court, approached the Supreme Court under Article 32 on the same facts seeking the same relief.
The Court held that where a High Court dismisses a writ petition on the merits after a contested hearing, that decision binds the parties and operates as res judicata against a fresh petition under Article 32 on the same cause — unless reversed in appeal. The Court was careful to confine the bar: a dismissal in limine without a speaking order, or on the ground of laches or an alternative remedy, would not raise the bar. Daryao thus imported the general principle of finality into the writ jurisdiction while preserving the sanctity of the Article 32 remedy. The maxim's procedural cousins are gathered in maxims relating to court proceedings.
Falsus in Uno, Falsus in Omnibus — Rejected in India
“False in one thing, false in everything.” This maxim, treated in parts of the common-law world as a rule for discrediting a witness who has lied on one point, has been firmly rejected by Indian courts. The leading authority is Gangadhar Behera v. State of Orissa, (2002) 8 SCC 381. Addressing the contention that the testimony of partly unreliable witnesses must be discarded wholesale, the Supreme Court held that the maxim has neither received general acceptance nor attained the status of a rule of law in India.
It is, the Court said, at most a rule of caution — all it means is that testimony may be disregarded, not that it must be disregarded. The duty of the court is to sift the grain from the chaff: where the evidence of a witness is partly true and partly exaggerated or false, the court must separate the reliable portion and act upon it, discarding only what is unworthy of belief. To reject the entire testimony because one part is untrue would be to surrender the judicial function of appraisal. Gangadhar Behera is the standard citation for the rejection of the maxim and the embrace of a more discriminating approach to witness credibility — a theme explored further under maxims relating to evidence.
Ignorantia Juris Non Excusat — Ignorance of Law Is No Excuse
“Ignorance of the law excuses not.” Every person is presumed to know the law of the land, and a plea of ignorance of the law is, as a rule, no defence to a charge or a civil claim. Indian courts apply the maxim as a working presumption rather than as an absolute bar. It is reflected in the criminal law itself: the General Exceptions in the Penal Code (now Sections corresponding to the Bharatiya Nyaya Sanhita) protect a person who acts under a mistake of fact, but pointedly not a person who acts under a mistake of law. A genuine mistake of fact may excuse; a mistake of law generally does not.
The rationale is practical necessity. If ignorance of the law were a defence, every accused could escape by professing not to have known the rule, and the administration of justice would collapse. The presumption that the law — once duly enacted and published — is known to all is the price of a workable legal order. The maxim must be read alongside its companion, ignorantia facti excusat (ignorance of fact excuses): a person who acts under an honest and reasonable mistake of fact may be protected, while a person who simply did not know the law is not. The distinction draws the line between the excusable and the inexcusable.
Indian benches have, however, recognised that the maxim must be applied with some sensitivity where a provision is genuinely obscure or where ignorance bears on the question of intention rather than on knowledge of the prohibition itself. Where a statute makes knowledge of a particular fact or notification an ingredient of the offence, the prosecution must still prove that ingredient; the maxim cannot be stretched to dispense with proof of a statutory element. But as a freestanding defence to liability, ignorance of the law remains, by settled rule, no excuse.
Locus Standi — Relaxed for Public Interest
The traditional rule of locus standi permitted only a person whose own legal right was infringed to move the court. That rule was dramatically relaxed in S.P. Gupta v. Union of India, AIR 1982 SC 149 (the First Judges Case). The Supreme Court held that where a legal wrong is caused to a person or a determinate class of persons who, by reason of poverty, disability or a socially or economically disadvantaged position, cannot themselves approach the court, any member of the public or social-action group acting bona fide may move the court on their behalf.
Procedure, the Court declared, is but a handmaiden of justice and must not bar access to the weaker sections of society. The judgment thereby laid the doctrinal foundation of public interest litigation in India and even endorsed “epistolary jurisdiction” — the power to treat a letter from a public-spirited person as a writ petition. S.P. Gupta shows how a procedural maxim, far from being immutable, can be reshaped by the courts to serve the larger end of justice. It is a reminder that maxims in India are servants of justice, not its masters.
Stare Decisis and Per Incuriam — The Limits of Precedent
“To stand by things decided.” Stare decisis is the principle that courts should follow their own past decisions and that lower courts are bound by higher ones — in India, reinforced by Article 141, which makes the law declared by the Supreme Court binding on all courts. But precedent is not absolute, and the maxim per incuriam (“through want of care”) marks one of its principal exceptions. A decision rendered in ignorance of a binding statutory provision or a binding precedent is said to be per incuriam and loses its authority as a precedent.
In A.R. Antulay v. R.S. Nayak, the Supreme Court explained that a decision can be treated as per incuriam when it is given in ignorance of the terms of a statute or of a binding authority, and that such a decision does not have the binding force of a precedent — though it continues to bind the parties to it inter se. The interplay of stare decisis and per incuriam shows how Indian courts maintain both consistency and the freedom to correct decisions reached without proper consideration of the law. Precedent is respected, but not at the cost of perpetuating error.
How to Deploy Maxims in an Exam Answer
For the judiciary or CLAT-PG candidate, the value of a maxim lies in pairing it with the case that gives it Indian content. Writing “audi alteram partem means hear the other side” earns little; writing “in Maneka Gandhi v. Union of India, AIR 1978 SC 597 the Court read audi alteram partem into Article 21 even where the statute was silent” earns marks because it shows application. The discipline is the same for each maxim: state the maxim, state its meaning in one line, then anchor it to a verified holding and the proposition that holding establishes.
Be equally ready to state where a maxim does not apply. The examiner who asks about falsus in uno, falsus in omnibus is usually testing whether you know that Gangadhar Behera rejected it as a rule of law in India. The candidate who can say both what a maxim means and how an Indian bench has treated it — applied, qualified, or rejected — demonstrates exactly the command the examiners are looking for. Build your revision around case-anchored maxims rather than bare definitions, and cross-check every citation, because a wrong AIR or SCC number undoes the credibility of an otherwise sound answer.
Frequently asked questions
Are legal maxims binding law in India?
No. A maxim is a condensed statement of a principle, not a rule of law in itself. Indian courts treat maxims as guides to reasoning that must yield to the language of a statute and to the justice of the case. Falsus in uno, falsus in omnibus, for example, was expressly rejected as a rule of law in Gangadhar Behera v. State of Orissa, (2002) 8 SCC 381.
Which case applied audi alteram partem to a passport impounded without a hearing?
Maneka Gandhi v. Union of India, AIR 1978 SC 597. The seven-judge bench held that procedure under Article 21 must be right, just and fair, and read audi alteram partem into the Passports Act even though the statute did not expressly require a hearing before impounding a passport.
What is the difference between actus reus and the maxim actus non facit reum nisi mens sit rea?
Actus reus is the guilty act; the maxim actus non facit reum nisi mens sit rea states that the act alone does not make a person guilty unless there is also a guilty mind (mens rea). In State of Maharashtra v. Mayer Hans George, AIR 1965 SC 722, the Court held the presumption of mens rea can be displaced for economic and regulatory offences, making the act itself sufficient.
How did res ipsa loquitur operate in Pushpabai Purshottam Udeshi?
In Pushpabai Purshottam Udeshi v. Ranjit Ginning & Pressing Co., AIR 1977 SC 1735, a car left the road and struck a tree with no eyewitness to the driving. The Supreme Court applied res ipsa loquitur: such an accident does not normally happen without negligence, so the burden shifted to the defendant to explain it without fault. The maxim shifts the evidentiary burden; it does not impose liability automatically.
Does ubi jus ibi remedium allow money compensation for breach of fundamental rights?
Yes. In Bhim Singh v. State of Jammu & Kashmir, AIR 1986 SC 494, an MLA was unlawfully arrested and prevented from attending the Assembly. Although already released, the Court applied the principle that a right must have a remedy and awarded ₹50,000 as exemplary compensation for the violation of his constitutional rights.
What makes a precedent per incuriam?
A decision is per incuriam when rendered in ignorance of a binding statutory provision or a binding precedent. As explained in A.R. Antulay v. R.S. Nayak, such a decision loses its value as a precedent under Article 141, though it still binds the parties to it inter se. It is a recognised exception to stare decisis.
