Legal Maxims in Tort Law: Meaning, Examples, and Important Principles
Legal maxims are concise Latin phrases that express important principles of law. Courts and lawyers have traditionally used them to explain legal rights, duties, liabilities, causes of harm, defences, and remedies. In tort law, these maxims are particularly useful because they present complex legal principles in a brief, clear, and memorable form.
Ubi Jus Ibi Remedium
Meaning: Where there is a right, there is a remedy.
If the law gives someone a legal right, the courts will normally provide a way to protect it when that right is broken.
Example: If A wrongly interferes with B’s right to possess property, B can ask for damages or an injunction.
Case: Ashby v. White (1703).
Injuria Sine Damno
Meaning: Legal injury without actual damage.
A person can sue even if no money has been lost, as long as a legal right has been violated.
Example: A is stopped from using a legal right. Even without financial loss, the interference itself may give a claim.
Case: Ashby v. White (1703).
Damnum Sine Injuria
Meaning: Damage without legal injury.
Actual loss alone does not create a tort claim unless a protected legal right has also been broken.
Example: A competes fairly with B, and B loses customers. The money loss by itself is not a tort.
Case: Gloucester Grammar School Case.
Right In Rem
Meaning: A right good against the whole world.
This kind of right can be enforced against anyone.
Example: Ownership of property means everyone else must respect the owner’s rights.
In tort law, rights to property, bodily safety and reputation usually work this way.
Right In Personam
Meaning: A right against a particular person.
This right can be enforced only against a specific person or group.
Example: A contract right to be paid by B is a right in personam.
Tort law mainly protects rights that apply to everyone, while contract rights are usually personal.
Volenti Non Fit Injuria
Meaning: To a willing person, no injury is done.
If someone freely and knowingly accepts a risk, they may not later claim damages for harm that comes from that risk.
Example: A spectator at a sports event accepts the ordinary dangers of watching the game.
Simply knowing about a risk is not the same as agreeing to it.
Scienti Non Fit Injuria
Meaning: No injury is done to one who knows.
This phrase is sometimes linked to the consent defense. Knowing a risk exists does not automatically mean the person has consented to it. Knowledge and consent are different things.
Res Ipsa Loquitur
Meaning: The thing speaks for itself.
When an accident is of a type that normally does not happen without negligence, and the defendant controlled the situation, the court may infer negligence from the facts alone.
Example: A heavy object falls from a building onto a passer-by.
This is only an evidence rule; it does not automatically prove liability.
Sic Utere Tuo Ut Alienum Non Laedas
Meaning: Use your own property so as not to harm another.
A person may use their property but must not unlawfully interfere with other people’s rights.
This idea is especially important in private nuisance cases.
Sic Utere Tuo Ut Temetipsum Non Laedam
Meaning: Use your property so as not to harm yourself.
This version is less common in tort law. The main rule is about not harming others, not about self-harm.
Qui Facit Per Alium Facit Per Se
Meaning: He who acts through another acts himself.
This maxim supports vicarious liability. An employer can be liable for a tort committed by an employee while doing the job.
Example: An employee carelessly injures a pedestrian while working; the employer may also be liable.
Respondeat Superior
Meaning: Let the superior answer.
This is another way of expressing the same idea: an employer can be held responsible for an employee’s torts done in the course of employment.
Qui Facit Per Se
Meaning: He who acts himself.
A person is normally responsible for their own wrongful acts. This stands in contrast to acting through someone else.
Injuria Non Remota Causa Sed Proxima
Meaning: Injury is attributed to the nearest cause, not a remote one.
Liability depends on the legally important (proximate) cause of the harm, not on distant events in the chain.
Causa Causans
Meaning: The immediate or effective cause.
This is the cause that the law treats as actually producing the result.
Example: A’s careless driving makes B’s car hit C; A’s negligence may be the effective cause.
Causa Sine Qua Non
Meaning: A cause without which the result would not have happened.
This is a necessary factual cause (the “but-for” test).
Factual causation alone is not enough; the harm must also not be too remote.
Novus Actus Interveniens
Meaning: A new intervening act.
An independent later event can break the chain of causation between the defendant’s conduct and the final damage.
Example: An unforeseeable independent event happens after the defendant’s act and causes extra harm; the defendant may not be liable for that extra harm.
Necessitas Non Habet Legem
Meaning: Necessity knows no law.
In extreme situations, necessity can justify an act that would otherwise be wrong.
Example: Entering someone’s land without permission to escape immediate danger may be allowed in some cases.
Damnum Absque Injuria
Meaning: Damage without legal injury.
This is simply another way of saying damnum sine injuria: loss without the violation of a legal right is not actionable.
Actionable Per Se
Meaning: Actionable by itself.
Some torts do not require proof of actual damage.
Example: Certain types of trespass can be sued upon even if no money has been lost.
Culpa Lata
Meaning: Gross negligence.
This describes a serious degree of carelessness.
It comes from older Roman and civil-law classifications and is not a precise modern common-law test.
Culpa Levis
Meaning: Slight or ordinary negligence.
A milder degree of fault in classical legal language.
Culpa Levis In Concreto
Meaning: Slight negligence judged by the particular circumstances.
Negligence is measured against the care the person usually takes in their own affairs.
Imperitia Culpae Adnumeratur
Meaning: Lack of skill is counted as negligence.
A person who takes on skilled work without the necessary ability can be liable if that lack of skill causes foreseeable harm.
This is important in professional negligence cases.
Culpa In Eligendo
Meaning: Fault in choosing.
Negligence in selecting an unsuitable person for a job.
Example: An employer carelessly hires an unqualified worker for skilled work and may face liability for that choice.
Scienter Rule
Meaning: Liability based on knowledge.
Traditionally applied to owners of dangerous animals: if the owner knew of the animal’s dangerous tendency, liability could follow.
Modern statutes have changed this rule in many places.
Innuendo
Meaning: An indirect or implied meaning.
In defamation, an innuendo is a meaning that only people with special background knowledge would understand.
A statement that looks harmless to ordinary readers may still be defamatory to those who know the extra facts.
Son Assault Demesne
Meaning: His own assault.
An old defense in assault and battery cases: the defendant claims the plaintiff started the fight and the defendant only used reasonable force in reply.
Today this is simply treated as self-defense.
De Mortuis Nil Nisi Bonum
Meaning: Speak nothing but good of the dead.
This traditional saying has limited modern legal force. Defamation law mainly protects the reputation of living persons; special rules may apply after death in some jurisdictions.
Ultra Vires
Meaning: Beyond the powers.
An act done outside the legal authority of a person or body.
Although mainly used in public and company law, it can matter in tort when an unlawful act by a public authority causes civil liability.
De Minimis Non Curat Lex
Meaning: The law does not concern itself with trifles.
Courts may ignore extremely small or unimportant matters.
Care is still needed, because even a minor breach of a clear legal right can sometimes give a claim.
Ex Turpi Causa Non Oritur Actio
Meaning: No action arises from an illegal or immoral cause.
A claimant may be barred from recovering if the claim is closely tied to their own serious wrongdoing.
The rule is applied carefully and depends on the facts and modern principles.
Actio Personalis Moritur Cum Persona
Meaning: A personal action dies with the person.
Historically, some claims ended when the claimant or defendant died. Modern statutes now allow many actions to continue for or against the estate of the deceased.
Conclusion
Legal maxims provide a useful starting point for understanding the principles of tort law. Expressions such as ubi jus ibi remedium, injuria sine damno, damnum sine injuria, volenti non fit injuria, and res ipsa loquitur, along with various causation maxims, help explain important concepts relating to rights, liability, negligence, consent, causation, defenses, and remedies.
However, not every Latin expression is a separate or independent rule of tort law. Some represent general legal principles, rules of evidence, historical pleas, or concepts derived from Roman and civil law. Their meaning and application must therefore be understood in their proper context and in light of the modern law applicable to the particular case.
