Tort Law Defenses: Identifying Invalid Defences

In tort law, a defense is a legal reason that allows a defendant to avoid liability, even if they committed a tortious act. Several defenses are recognized, but not all legal principles function as specific tort defenses. We need to identify which option listed is not a standard defense in tort.

Valid Tort Defences Explained

• Private Defence: This is a valid defense. It allows a person to use reasonable force to protect themselves, their property, or another person from imminent harm. The force used must be proportionate to the threat.
• Volenti non fit injuria: This Latin maxim means "to a willing person, injury is not done." It is a defense where the claimant voluntarily consented to, or accepted the risk of, the injury they suffered. For example, participating in a dangerous sport knowingly.
• Vis major: This translates to "superior force" or "Act of God." It refers to an extraordinary natural event or intervention that could not have been foreseen or prevented by human intervention (e.g., earthquakes, floods). It can absolve a party from liability if such an event directly causes the harm.

Invalid Tort Defence: Ex dolo malo non Oritur actio

The principle Ex dolo malo non Oritur actio is a general legal maxim meaning "an action does not arise from a deceit" or "from fraud, no action arises." While related to the concept that one cannot benefit from their own wrongdoing, it is not typically classified as a specific, standalone defense in tort law in the same way as the others listed. It's more fundamental principle often related to contract law or the overall claim's validity, rather than a procedural defense against an admitted tort. The other options are well-established defenses applicable directly within tortious claims.

Therefore, Ex dolo malo non Oritur actio is the correct answer as it is not considered a standard defense in tort law compared to the other options.
