Legal Maxims and Principles of Equity: Landmark Indian Cases
Study how courts apply Latin maxims, natural justice, clean hands, estoppel, restitution and equitable remedies. Each decision includes material facts, its legal issue, judicial reasoning and a link to the full judgment.
How to apply legal maxims correctly
Maxims express interpretative or remedial principles. Equity operates within the applicable Constitution, statutes and binding precedents. Courts cannot use a fairness slogan to contradict mandatory statutory text. The outcome depends on the actual legal right, remedy, facts, procedure and statutory context.
Statutory caution: Older cases involving the Indian Penal Code or the pre-2018 Specific Relief Act must be read against current legislation. References to equity never dispense with jurisdiction or limitation requirements.

Abhishek Gupta v. Dinesh Kumar
2025 INSC 1406 · 2025 · Supreme Court of India · Judgment: 3 December 2025
Legal issue: Whether an affected non-party could maintain an intra-court appeal against an order concerning a fair-price-shop licence.
Read detailed case analysis
Maxim and its meaning
Ubi jus ibi remedium
Material facts
A licence was transferred after cancellation of an earlier licensee’s authorisation. A Single Judge ordered restoration without joining the replacement licensee. The affected replacement licensee appealed, but the Division Bench rejected the special appeal as not maintainable.
Judgment and binding principle
The Supreme Court set aside the Division Bench ruling and restored the special appeal. A party adversely affected without an opportunity to participate must not be left without an effective remedy. Where non-joinder of a necessary party has merit, the appellate court may remand or decide the matter appropriately.
Why this case matters
A direct 2025 application of the maxim. It does not remove statutory conditions for appeals generally; the ruling addresses the procedural setting and interests of an affected non-party.
Subsequent treatment or caution
The merits of competing claims to the fair-price-shop licence were left open.
Court directions
The special appeal was restored for expeditious disposal.

Rudul Sah v. State of Bihar
(1983) 4 SCC 141 · 1983 · Supreme Court of India · Judgment: 1 August 1983
Legal issue: Can an Article 32 court award money to someone unlawfully imprisoned after acquittal?
Read detailed case analysis
Maxim and its meaning
Ubi jus ibi remedium; constitutional compensation
Material facts
Rudul Sah remained imprisoned for more than fourteen years after a criminal court acquitted him. He sought release and relief against the State.
Judgment and binding principle
The Court held that a merely declaratory order would not adequately vindicate the Article 21 injury. It ordered monetary compensation as a public-law response, without barring a separate civil damages suit.
Why this case matters
The decision demonstrates that constitutional remedies can be adapted to a proved fundamental-rights violation. It does not mean every actionable wrong automatically earns compensation under Article 32.
Subsequent treatment or caution
Later public-law compensation cases have developed this remedy.
Court directions
The State was directed to pay an additional Rs 30,000 besides Rs 5,000 already paid.

Bhim Singh v. State of Jammu and Kashmir
(1985) 4 SCC 677 · 1985 · Supreme Court of India · Judgment: 22 November 1985
Legal issue: Can a court grant compensation for illegal detention that obstructed an elected representative’s functions?
Read detailed case analysis
Maxim and its meaning
Injuria sine damno; constitutional redress
Material facts
An MLA was arrested and kept from attending an Assembly sitting. The Court examined the irregularities in his arrest and production before a magistrate.
Judgment and binding principle
The arrest and detention violated constitutional rights. The Supreme Court awarded exemplary monetary relief in constitutional proceedings against the State.
Why this case matters
The case is used to distinguish violation of a protected legal right from proof of pecuniary loss. The decisive ground is constitutional injury, not a freestanding entitlement for every political grievance.
Subsequent treatment or caution
A leading example of public-law compensation for loss of liberty.

Nilabati Behera v. State of Orissa
(1993) 2 SCC 746 · 1993 · Supreme Court of India · Judgment: 24 March 1993
Legal issue: Is compensation available for custodial death apart from ordinary private-law damages?
Read detailed case analysis
Maxim and its meaning
Ubi jus ibi remedium; public-law restitution
Material facts
A mother pursued constitutional relief after her son died following police custody. The case examined the State’s responsibility for a grave infringement of Article 21.
Judgment and binding principle
The Court recognised compensation under Articles 32 and 226 as a public-law remedy for established infringements of fundamental rights. Such relief is distinct from private-law damages, and the principle of sovereign immunity does not defeat it.
Why this case matters
Read alongside Rudul Sah to track the maturation of constitutional tort remedies and the evidentiary burden needed to establish State responsibility.
Subsequent treatment or caution
Public-law compensation is supplemental to other available proceedings.

02 · Audi alteram partem and nemo judex in causa sua
State of Orissa v. Dr (Miss) Binapani Dei
AIR 1967 SC 1269 · 1967 · Supreme Court of India · Judgment: 7 February 1967
Legal issue: Could a public authority change an employee’s recorded birth date with serious service consequences without hearing her?
Read detailed case analysis
Maxim and its meaning
Audi alteram partem
Material facts
An administrative inquiry revised a government doctor’s birth date, effectively advancing her retirement. Material used against her was not adequately disclosed.
Judgment and binding principle
An order with civil consequences must be made consistently with natural justice, even if the decision is administrative rather than strictly judicial. The affected person should be informed and given a fair opportunity to answer the material.
Why this case matters
Foundational authority for the proposition that substantive fairness is not limited to proceedings labelled quasi-judicial.

Gullapalli Nageswara Rao v. Andhra Pradesh State Road Transport Corporation
AIR 1959 SC 308 · 1958 · Supreme Court of India · Judgment: 5 November 1958
Legal issue: Was a transport nationalisation decision valid where an involved departmental secretary heard objections and another authority decided?
Read detailed case analysis
Maxim and its meaning
Nemo judex in causa sua; he who hears must decide
Material facts
Private bus operators objected to a transport-nationalisation scheme. The Secretary associated with the undertaking conducted hearings, but the Chief Minister gave the final decision.
Judgment and binding principle
By a majority, the Court held the procedure contrary to natural justice. The interested hearing officer could not fairly preside, and the separation of the hearing function from the decision also mattered. The order approving the scheme was quashed.
Why this case matters
The first Gullapalli ruling must not be confused with the distinct 1959 follow-up, which considered a later hearing conducted by the Chief Minister himself.
Subsequent treatment or caution
See the later 1959 decision on a revised procedure.
Court directions
The approval of the scheme was quashed.
Separate or dissenting opinion
Two judges disagreed with the majority’s analysis of the statutory procedure.

Gullapalli Nageswara Rao v. State of Andhra Pradesh
AIR 1959 SC 1376 · 1959 · Supreme Court of India · Judgment: 21 August 1959
Legal issue: Was the Chief Minister disqualified from hearing objections in the fresh transport-nationalisation process?
Read detailed case analysis
Maxim and its meaning
Nemo judex in causa sua; apparent bias
Material facts
After the earlier scheme approval was quashed, the Chief Minister personally heard objections and approved the scheme. Operators again alleged official bias.
Judgment and binding principle
The Supreme Court rejected the renewed challenge. A Minister’s policy responsibility was not equivalent to the earlier secretary’s direct institutional conflict. The particular circumstances did not establish disqualifying bias.
Why this case matters
The pair of Gullapalli decisions illustrates that bias is assessed through actual institutional roles and statutory context, not by repeating a maxim mechanically.
Subsequent treatment or caution
The 1958 and 1959 decisions concern successive proceedings with different outcomes.

A.K. Kraipak v. Union of India
(1969) 2 SCC 262 · 1969 · Supreme Court of India · Judgment: 29 April 1969
Legal issue: Could a selection committee include a candidate who also participated in consideration of competing candidates?
Read detailed case analysis
Maxim and its meaning
Nemo judex in causa sua; duty to act fairly
Material facts
A senior forest officer, himself a candidate for selection to the Indian Forest Service, sat on the selection board when the merits of competitors were discussed.
Judgment and binding principle
The selection was vitiated by the reasonable likelihood of bias. Natural justice can govern administrative action, and formal abstention during consideration of one’s own name does not cure participation in decisions affecting rivals.
Why this case matters
The decision explains why decision-making integrity is assessed across the entire process. Later ratification cannot necessarily cure a tainted foundational recommendation.
Subsequent treatment or caution
Still a foundational bias decision.

Swadeshi Cotton Mills v. Union of India
(1981) 1 SCC 664 · 1981 · Supreme Court of India · Judgment: 13 January 1981
Legal issue: When may urgency and statutory scheme qualify the requirement of a hearing before government takeover?
Read detailed case analysis
Maxim and its meaning
Audi alteram partem; procedural fairness
Material facts
The Union took over several industrial undertakings under the Industries (Development and Regulation) Act. The company disputed the order and the lack of an effective prior hearing.
Judgment and binding principle
The opinions examined whether natural justice was excluded by statutory implication and how much hearing was practicable. They emphasised statutory context, administrative urgency and meaningful procedural fairness rather than an inflexible formula.
Why this case matters
Use the different opinions carefully. It is an authority on the flexible content of natural justice, not a blanket rule that every urgent decision requires identical procedure.
Subsequent treatment or caution
Its application turns on the governing legislation and urgency of action.

Ranjit Thakur v. Union of India
(1987) 4 SCC 611 · 1987 · Supreme Court of India · Judgment: 15 October 1987
Legal issue: Did a court-martial proceeding meet impartiality requirements, and was the punishment grossly disproportionate?
Read detailed case analysis
Maxim and its meaning
Nemo judex in causa sua; proportionality
Material facts
A soldier was tried by court martial after incidents involving disobedience. A superior previously involved in punishing him participated in the later process.
Judgment and binding principle
The Court applied the reasonable-apprehension standard of bias and examined proportionality of punishment. Judicial review could intervene where procedural unfairness and extreme disproportionality undermined the decision.
Why this case matters
Important for distinguishing apparent bias from demonstrated personal hostility and for linking fairness with proportionality.

03 · Clean hands, fraud and equitable relief
S.P. Chengalvaraya Naidu v. Jagannath
(1994) 1 SCC 1 · 1993 · Supreme Court of India · Judgment: 27 October 1993
Legal issue: What is the effect of a decree obtained through deliberate suppression of an essential document?
Read detailed case analysis
Maxim and its meaning
Fraus omnia corrumpit; he who comes to equity must come with clean hands
Material facts
The successful claimant concealed a release deed related to the property while pursuing a partition claim. That omission distorted the court’s understanding of title.
Judgment and binding principle
The Supreme Court held that fraud on the court vitiates the judicial act. A litigant knowingly withholding a vital document to obtain an advantage cannot preserve a decree produced by deception.
Why this case matters
A leading clean-hands authority. Fraud must be properly alleged and proved; ordinary evidentiary error is not automatically fraud on the court.
Subsequent treatment or caution
Reported in 1994 though decided in 1993.

Prestige Lights Ltd v. State Bank of India
(2007) 8 SCC 449 · 2007 · Supreme Court of India · Judgment: 20 August 2007
Legal issue: Should writ relief be available to a borrower concealing material facts about mortgaged property?
Read detailed case analysis
Maxim and its meaning
He who seeks equity must do equity; clean hands
Material facts
A company disputed recovery proceedings by its bank while withholding material information about dealings affecting secured assets and failing to comply with relevant undertakings.
Judgment and binding principle
The Supreme Court refused discretionary relief. A party invoking Articles 226 or 136 must candidly disclose material facts, especially when asking the court for equitable intervention.
Why this case matters
Clean hands is a constraint on discretionary jurisdiction. It does not authorise courts to disregard mandatory statutory rights without applying the law.

Dalip Singh v. State of Uttar Pradesh
(2010) 2 SCC 114 · 2009 · Supreme Court of India · Judgment: 3 December 2009
Legal issue: What follows when a party attempts to secure relief through false statements and suppression?
Read detailed case analysis
Maxim and its meaning
Ex turpi causa non oritur actio; clean hands
Material facts
The appeal arose from land-related proceedings in which disclosures and the litigant’s conduct were materially questioned.
Judgment and binding principle
The Court condemned dishonest litigation and stressed the duty of candour owed by anyone seeking discretionary relief. It declined to reward misrepresentation in judicial proceedings.
Why this case matters
The 2009 decision carries a 2010 SCC citation. Its ethical warning is important, but findings of deception must remain tied to the proved record.

04 · Promissory estoppel and fair government action
Motilal Padampat Sugar Mills Co. Ltd v. State of Uttar Pradesh
(1979) 2 SCC 409 · 1978 · Supreme Court of India · Judgment: 12 December 1978
Legal issue: Can a government promise of tax relief bind the State when a business has acted on the representation?
Read detailed case analysis
Maxim and its meaning
Promissory estoppel
Material facts
A sugar manufacturing undertaking relied upon representations about a proposed sales-tax exemption while making investment and business decisions.
Judgment and binding principle
The Supreme Court explained that promissory estoppel can operate against government action where a clear representation induces reliance and inequity would result from withdrawal. It cannot compel conduct prohibited by law.
Why this case matters
Do not confuse the judgment date, December 1978, with the 1979 law-report year. Analyse the promise, reliance, statutory power and overriding public interest separately.
Subsequent treatment or caution
Later cases refine the public-interest and statutory-limit exceptions.

State of Punjab v. Nestle India Ltd
(2004) 6 SCC 465 · 2004 · Supreme Court of India · Judgment: 5 May 2004
Legal issue: Can the State retrospectively demand purchase tax after announcing relief relied upon by milk-processing businesses?
Read detailed case analysis
Maxim and its meaning
Promissory estoppel; public authority must act consistently
Material facts
The State’s public representations about purchase tax on milk induced commercial planning and expenditure. It later demanded tax for the period in dispute.
Judgment and binding principle
The Court upheld relief on the specific facts and required the State to act consistently with a supported promise. The statutory power to exempt and lack of a demonstrated overriding public-interest reason were material.
Why this case matters
The case does not establish that a ministerial speech alone alters tax law. The existence of lawful power, reliance and the specific remedy must all be checked.
Subsequent treatment or caution
Read with limits on estoppel against mandatory statutory prohibitions.

05 · Delay defeats equity and limitation
State of Madhya Pradesh v. Bhailal Bhai
AIR 1964 SC 1006 · 1964 · Supreme Court of India · Judgment: 20 January 1964
Legal issue: Can delayed writ petitions seeking refunds succeed despite substantial lapse of time?
Read detailed case analysis
Maxim and its meaning
Vigilantibus non dormientibus jura subveniunt; laches
Material facts
The disputes involved taxes collected under provisions later challenged as unconstitutional and requests for restitution through Article 226 petitions.
Judgment and binding principle
The Court recognised that a High Court may refuse discretionary relief where the delay is unreasonable. Limitation periods for civil suits can guide, without mechanically determining, the exercise of writ jurisdiction.
Why this case matters
Distinguish statutory limitation, which binds on its terms, from equitable laches in discretionary writ proceedings.

K.S. Vidyanadam v. Vairavan
(1997) 3 SCC 1 · 1997 · Supreme Court of India · Judgment: 6 February 1997
Legal issue: Could a buyer obtain specific performance after prolonged inaction despite a specified time for completion?
Read detailed case analysis
Maxim and its meaning
Delay defeats equity; equitable relief follows contractual discipline
Material facts
A property purchaser delayed taking the steps needed to complete a sale, while property values and circumstances changed.
Judgment and binding principle
Applying the then-governing discretionary specific-performance law, the Court refused to treat contractual time stipulations as meaningless merely because time was not ordinarily of the essence for immovable property.
Why this case matters
Historical-law caution: the Specific Relief (Amendment) Act, 2018 materially changed the framework under Section 10. Do not treat pre-2018 discretion as the unchanged modern statutory test.
Subsequent treatment or caution
Read alongside the amended Specific Relief Act, 1963; factual delay and readiness remain relevant under applicable provisions.

Shivamma (Dead) by LRs v. Karnataka Housing Board
2025 INSC 1104 · 2025 · Supreme Court of India · Judgment: 12 September 2025
Legal issue: Could extraordinary delay by a government instrumentality be condoned without genuine sufficient cause?
Read detailed case analysis
Maxim and its meaning
Vigilantibus non dormientibus jura subveniunt; limitation and laches
Material facts
A housing board obtained condonation of 3,966 days of delay in bringing a second appeal in a land dispute. The affected landholder challenged that indulgence.
Judgment and binding principle
The Supreme Court set aside condonation and gave detailed guidance on Section 5 of the Limitation Act. Administrative lethargy is not a sufficient explanation by itself; reasons and bona fides must be established, including when the applicant is the State.
Why this case matters
An authoritative 2025 decision demonstrating that the equitable vigilance maxim operates alongside statutory limitation. The length of delay matters, but the adequacy of cause remains central.
Subsequent treatment or caution
The appeal was allowed and the condonation order set aside.
Court directions
The Registry was directed to circulate the judgment to High Courts.

06 · Act of court, restitution and unjust enrichment
A.R. Antulay v. R.S. Nayak
(1988) 2 SCC 602 · 1988 · Supreme Court of India · Judgment: 29 April 1988
Legal issue: Can a party be compelled to suffer the consequences of an earlier judicial direction inconsistent with the statutory trial forum?
Read detailed case analysis
Maxim and its meaning
Actus curiae neminem gravabit
Material facts
Earlier Supreme Court directions had shifted the trial of criminal allegations against a former Chief Minister to a forum not contemplated by the special law. The accused challenged that transfer.
Judgment and binding principle
The Supreme Court recognised that it could correct its own earlier error to protect fundamental procedural rights. Judicial orders cannot lawfully deprive a party of the forum and procedure guaranteed by statute.
Why this case matters
A key example of remedial self-correction. Distinguish correction of a specific judicial mistake from unrestricted reopening of final decisions.
Subsequent treatment or caution
The decision contains several separately reasoned opinions; consult the full bench opinions before citing a particular proposition.
Court directions
The case was restored to the lawful special-trial process.
Separate or dissenting opinion
There were differing opinions on recall and the appropriate legal route.

South Eastern Coalfields Ltd v. State of Madhya Pradesh

Legal issue: Should a litigant restore gains enjoyed under interim protection when the underlying challenge ultimately fails?
Read detailed case analysis
Maxim and its meaning
Actus curiae neminem gravabit; restitution
Material facts
Coal companies and consumers contested enhanced mineral royalty. Interim orders had affected collection pending judicial determination.
Judgment and binding principle
The Court explained restitution as a response to the unfair advantage generated by interim court orders. Courts may neutralise benefits improperly retained because proceedings delayed enforcement of a valid demand.
Why this case matters
For exam answers, separate restitution from punishment. The purpose is to restore the proper balance, not confer a windfall on the successful party.

Indian Council for Enviro-Legal Action v. Union of India

Legal issue: How should courts respond to prolonged non-compliance that creates unjust benefit through litigation delay?
Read detailed case analysis
Maxim and its meaning
Restitutio in integrum; unjust enrichment
Material facts
Industrial pollution litigation remained active long after a final environmental restoration order. Interlocutory proceedings were used to resist compliance and payment.
Judgment and binding principle
The Court elaborated restitution and unjust enrichment, stressing that court procedures must not become instruments for withholding sums or benefits owed under binding orders.
Why this case matters
A major authority for restoring the position that would have existed without procedural misuse. Read the 2011 ruling separately from the original environmental judgment of 1996.
Subsequent treatment or caution
The Court directed steps to secure compliance with its previous orders.

Prem Aggarwal v. Mohan Singh
2025 INSC 1214 · 2025 · Supreme Court of India · Judgment: 7 October 2025
Legal issue: Could a litigant retain property possession while rejecting a substantial compensatory award after losing a specific-performance suit?
Read detailed case analysis
Maxim and its meaning
Actus curiae neminem gravabit; equity prevents unjust enrichment
Material facts
Following dismissal of a specific-performance suit, the Supreme Court had directed compensation of Rs 2 crore in relation to an earnest payment of Rs 25,000. The appellant refused the amount and resisted possession proceedings.
Judgment and binding principle
The Supreme Court upheld execution and explained that an omission in its earlier order should not prejudice the successful parties. A litigant could not retain both possession and the benefit of extraordinary compensation.
Why this case matters
An explicit modern application of actus curiae and anti-windfall reasoning. The holding is tied to the unusual procedural history and equitable adjustment already ordered.
Subsequent treatment or caution
The challenge to warrants of possession was dismissed.
Court directions
The Court upheld delivery of possession with police assistance if necessary.

07 · Statutory interpretation maxims
Amar Chandra Chakraborty v. Collector of Excise
(1972) 2 SCC 442 · 1972 · Supreme Court of India · Judgment: 3 May 1972
Legal issue: When may apparently general words be restricted to the same class as more specific preceding expressions?
Read detailed case analysis
Maxim and its meaning
Ejusdem generis
Material facts
The case concerned the power to withdraw an excise licence under provisions of the Bengal Excise Act. Parties disputed the reach of statutory language.
Judgment and binding principle
The Court explained conditions for ejusdem generis, including the existence of a discernible class within the specific words and a context supporting a restricted reading. The maxim is a contextual aid, not an automatic rewriting device.
Why this case matters
An essential authority for applying the genus test carefully rather than narrowing all general expressions.

Siddeshwari Cotton Mills (P) Ltd v. Union of India

Legal issue: How should a phrase concerning fabric processing be interpreted alongside surrounding statutory words?
Read detailed case analysis
Maxim and its meaning
Ejusdem generis; noscitur a sociis
Material facts
Cotton fabric processing and excise classification depended on whether the manufacturing operation fell within a statutory grouping of treatment processes.
Judgment and binding principle
The Court used the surrounding statutory terms and their shared character to explain the contested expression. Context rather than isolated dictionary meaning controlled the inquiry.
Why this case matters
Compare ejusdem generis with noscitur a sociis. A shared context may reveal meaning without every list satisfying the technical requirements of ejusdem generis.

Nathi Devi v. Radha Devi Gupta
(2005) 2 SCC 271 · 2004 · Supreme Court of India · Judgment: 17 December 2004
Legal issue: How should special statutory eviction rights be interpreted where the legislature specified limited conditions?
Read detailed case analysis
Maxim and its meaning
Expressio unius est exclusio alterius; casus omissus
Material facts
A widow landlady sought eviction under a particular provision of the Delhi Rent Control Act. The tenant disputed whether the qualifying statutory circumstances were satisfied.
Judgment and binding principle
The Court emphasised legislative text, statutory structure and the limits of judicial supplementation. Courts should not ordinarily supply missing conditions or exceptions merely because another reading appears more convenient.
Why this case matters
A useful case for the restraint behind casus omissus. The maxim is subordinate to the whole statute and evident legislative scheme.

The SCC citation is from 2005 though the judgment was delivered in 2004.

Satyadhyan Ghosal v. Deorajin Debi
AIR 1960 SC 941 · 1960 · Supreme Court of India · Judgment: 20 April 1960
Legal issue: Can a matter decided earlier in the same litigation ordinarily be reopened at a later stage?
Read detailed case analysis
Maxim and its meaning
Interest reipublicae ut sit finis litium; res judicata
Material facts
The dispute arose from successive stages of eviction litigation and changes in tenancy law. Earlier decisions determined issues that the parties attempted to revisit.
Judgment and binding principle
The Supreme Court explained res judicata as a rule of finality in the interest of parties and society. It applies, where its conditions are met, to successive stages of the same proceedings as well as separate proceedings.
Why this case matters
Connect the maxim to Section 11 of the Code of Civil Procedure, 1908, while recognising exceptions and the context of appellate correction.

Legal issue: Can an adjudicated land-ceiling issue be reopened in later proceedings involving the same material controversy?
Read detailed case analysis
Maxim and its meaning
Res judicata; issue estoppel
Material facts
A plantation company and land authorities engaged in repeated rounds of land-ceiling disputes. Arguments resurfaced over issues previously determined.
Judgment and binding principle
The Court examined finality, issue estoppel and their relation to adjudicatory consistency. Matters actually and necessarily resolved cannot ordinarily be relitigated by the same parties in a new form.
Why this case matters
Distinguish claim preclusion from issue preclusion, and check party identity, prior competence, finality and whether the precise issue was decided.

09 · Mens rea and trivial harms
Nathulal v. State of Madhya Pradesh
AIR 1966 SC 43 · 1965 · Supreme Court of India · Judgment: 22 March 1965
Legal issue: Is criminal liability established without a culpable state of mind when an offence-creating statute does not clearly exclude mens rea?
Read detailed case analysis
Maxim and its meaning
Actus non facit reum nisi mens sit rea
Material facts
A trader held substantial foodgrain stock after applying for a licence and believing permission would be granted. He was prosecuted under essential-commodities legislation.
Judgment and binding principle
The Court applied the presumption that mens rea is required unless the statutory scheme excludes it expressly or by necessary implication. On the facts, the prosecution did not establish the necessary guilty mind.
Why this case matters
The presumption is not absolute: some regulatory offences impose strict liability. Always read the offence definition and relevant statutory exceptions.

Legal issue: When does the law disregard a harm so slight that no person of ordinary sense would complain?
Read detailed case analysis
Maxim and its meaning
De minimis non curat lex
Material facts
Following an altercation between neighbours, criminal allegations raised the exception for acts causing slight harm under the Indian Penal Code.
Judgment and binding principle
The Court interpreted former Section 95 IPC by reference to the nature of the harm and the circumstances, rather than treating every physical act as inevitably too serious for the exception.
Why this case matters
For modern examination work, cross-check the corresponding provision under the Bharatiya Nyaya Sanhita, 2023, because the judgment applied the former IPC.

10 · Public trust and equitable stewardship
M.C. Mehta v. Kamal Nath
(1997) 1 SCC 388 · 1996 · Supreme Court of India · Judgment: 13 December 1996
Legal issue: May the State permit private occupation or alteration of environmentally significant river land inconsistent with public trust obligations?
Read detailed case analysis
Maxim and its meaning
Public trust doctrine; equitable stewardship
Material facts
The litigation challenged a motel-linked lease and activities affecting the River Beas and surrounding land.
Judgment and binding principle
The Supreme Court recognised the public trust doctrine as part of Indian law and invalidated the relevant lease. State authorities must protect certain shared natural resources, rather than deal with them as unrestricted private assets.
Why this case matters
An important equity-derived public-law principle. The operative environmental remedies arise from constitutional and environmental law, not simply classical private trusts.
Subsequent treatment or caution
The 1997 SCC report follows the 1996 judgment date.
Court directions
The Court directed restoration and assessment of ecological damage.
