Definition
Damage without injury.
Loss suffered but no actionable legal wrong.
Etymology & Origin
From Latin 'damnum' (loss, damage, harm), 'sine' (without), and 'injuria' (legal wrong, violation of a right — from 'in-' (not) and 'jus' (right, law)). The phrase literally means 'damage without legal wrong.' It expresses the tort law principle that financial or other loss by itself does not give rise to a legal claim — there must also be a violation of a legally recognised right. The maxim entered Indian tort jurisprudence through English common law and is applied by Indian courts to dismiss claims where loss was suffered but no legal right was infringed.
Full Legal Analysis
Damnum sine injuria — 'damage without legal wrong' — is the tort law principle that mere loss or damage, however substantial, does not by itself give rise to a cause of action unless the plaintiff's legal right has been violated. The fact that the defendant's lawful act caused the plaintiff financial ruin is not, without more, actionable in law. The law of torts protects legal rights, not economic interests generally. A plaintiff who suffers harm from another's lawful exercise of their own rights has no remedy in tort.
The principle is the counterpart of injuria sine damno — legal wrong without damage — where the violation of a legal right is actionable even without provable financial loss (as in trespass to land or defamation per se). Together, these two maxims define the scope of actionable harm in tort: the defendant must have violated a legal right of the plaintiff (injuria), and ordinarily there must also be some resulting damage (damnum) to constitute an actionable tort. Where one of the two is absent, the claim fails.
The classic English illustration is the Gloucester Grammar School Case (1410), where a schoolmaster set up a competing school, causing financial loss to an established school — held not actionable because the competitor was exercising his lawful right to carry on a trade. In Mogul Steamship Co. v. McGregor Gow (1892), shipping companies who drove a competitor out of business by lowering rates and offering preferential treatment to customers were held not liable — competing in trade, even aggressively, does not violate any legal right of the competitor.
The Gujarat High Court held that a plaintiff who suffered mental distress and hurt to religious sentiments from the exhibition of a film depicting a goddess in a manner she found objectionable had suffered damnum but not injuria — there is no legal right to prevent others from exhibiting a film simply because its content causes mental or religious distress. The hurt to feelings, however genuine, did not constitute a violation of a legally recognised right.
The principle has constitutional dimensions in Indian law. Economic regulation by the State that causes financial loss to a business — through price controls, licensing restrictions, or market regulation — is generally not actionable as a legal wrong if the regulation is within the State's legislative competence. The loss caused is damnum sine injuria: real financial harm, but no violation of a fundamental right since business regulation per se is permissible under Article 19(6) of the Constitution.
For advocates assessing whether a client has a viable tort claim, the first question must be: what legal right of the client has the defendant violated? If the only complaint is that the defendant's lawful activity caused the client financial loss — through competition, price undercutting, or better service — the claim will fail at the threshold under damnum sine injuria. The client's feeling of unfairness is not a legal wrong, and no court will grant relief on that basis alone.
