The problem before the rule
Can serious financial loss exist without any legal wrong?
A opens a lawful coaching centre beside B, charges lower fees and attracts most of B's students without deception or interference.
Reveal the legal analysis
B suffers economic loss, but no legal right is violated. This is damnum sine injuria.
Always identify the specific legal right before treating factual loss as actionable damage.The shortest useful answer
Tort law protects legal rights, so a right may be actionable without loss while loss alone may remain non-actionable.
- Apply both maxims to short problem questions.
- Distinguish factual damage from legal injury.
- Use the leading cases for their precise function.
Doctrine 01
Injuria sine damno
A claimant may succeed because a legal right was violated even without measurable financial loss.
- Meaning
- Injuria means infringement of a legal right, while sine damno means without actual or measurable damage.
- Actionable per se
- Some rights, including voting, liberty and certain trespass protections, support an action upon violation itself.
- Remedy
- Nominal damages, compensation or public-law relief may vindicate the right depending on the cause of action.
Doctrine 02
Damnum sine injuria
Competition and other lawful conduct may cause serious loss without creating tort liability.
- Meaning
- Damnum means actual harm or loss, while sine injuria means without infringement of a legal right.
- Lawful competition
- A business may lose customers because a competitor offers a better service, provided no independent wrong is committed.
- Limits
- The maxim does not protect conduct involving nuisance, defamation, intimidation, unlawful means or violation of statute.

The cases that move the rule
A citation is useful only when you can explain what changed after the court spoke.
Core authority
Ashby v. White
(1703) 2 Ld Raym 938
- Facts that matter
- A qualified voter was wrongfully prevented from voting, although the candidate he supported won the election.
- The legal question
- Is denial of a legal right actionable when the claimant proves no financial loss and the final election result is unchanged?
- The holding
- Wrongful denial of a qualified voter's vote was actionable despite the preferred candidate winning and no proven financial loss.
- Why the court got there
- The right to vote required a remedy upon violation. The absence of measurable loss did not erase the legal injury.
- Where it earns its place
- Use it as the classic example of injuria sine damno.
Core authority
Gloucester Grammar School Case
(1410) YB 11 Hen IV
- Facts that matter
- A schoolmaster opened a competing school nearby, charged lower fees and drew pupils away from the established school.
- The legal question
- Does economic loss caused by lawful competition amount to a legal injury?
- The holding
- Lawful competition causing loss of pupils and fees did not violate a legal right.
- Why the court got there
- The claimant had no legal right to be free from honest competition. Loss alone could not create liability without an independent wrong.
- Where it earns its place
- Use it as the classic example of damnum sine injuria.
Core authority
Bhim Singh v. State of Jammu and Kashmir
AIR 1986 SC 494
- Facts that matter
- A legislator was unlawfully arrested and detained so that he could not attend a session of the legislative assembly.
- The legal question
- What remedy can vindicate personal liberty after the detention has already achieved its unlawful purpose?
- The holding
- Unlawful detention that prevented a legislator from attending the assembly justified monetary compensation for violation of personal liberty.
- Why the court got there
- Release alone was inadequate. Monetary compensation was necessary to respond meaningfully to the completed constitutional violation.
- Where it earns its place
- Use it as the Indian constitutional illustration of an actionable violation of legal right.

Can nominal damages vindicate a right?
Questions students actually ask
Clear the last two doubts
Is actual financial loss essential in every tort?
No. Violation of an actionable legal right may itself support relief.
Is every business loss caused by competition non-actionable?
Only lawful competition is protected. Independent wrongs such as deceit, nuisance or unlawful interference remain actionable.
