Illegality

Topic

Illegality in Tort Law

The defence of illegality, also known as ex turpi causa non oritur actio, is a principle in tort law that prevents claimants from recovering damages if their claim arises from their own illegal or immoral conduct. This doctrine is based on the idea that courts should not assist a person in profiting from their wrongdoing. The defence is applied to uphold the integrity of the legal system and public policy, ensuring that individuals do not benefit from their unlawful actions.

Principle of Illegality

The defence of illegality operates under the following key principles:

  • ★ Ex Turpi Causa: The Latin maxim "ex turpi causa non oritur actio" means "from a dishonorable cause, an action does not arise." It prohibits claimants from seeking legal remedy if their claim is founded on an illegal act or immoral conduct.
  • ★ Policy Rationale: The doctrine serves to protect the integrity of the legal system, prevent individuals from profiting from their wrongdoing, and maintain public confidence in the administration of justice.
  • ★ Balancing Justice and Public Policy: Courts must balance the principles of justice, fairness, and public policy. They consider whether applying the defence would lead to an unjust outcome or encourage unlawful behavior.

Application of Illegality

The application of the defence depends on the circumstances of each case, particularly the nature of the illegal conduct and its connection to the claim:

  • ★ Direct Connection: For the defence to succeed, there must be a direct link between the claimant's illegal conduct and the claim. The wrongdoing must be integral to the cause of action, not merely incidental.
  • ★ Proportionality: The court considers whether applying the defence would be disproportionate to the seriousness of the illegality. This involves evaluating the gravity of the unlawful act and the harm suffered by the claimant.
  • ★ Public Policy Considerations: Courts weigh public policy considerations, such as deterring illegal conduct and upholding the integrity of the legal system. They avoid outcomes that would condone or encourage unlawful behavior.

Case Law

Patel v Mirza (2016)

This landmark case redefined the approach to the illegality defence. The UK Supreme Court established a structured test, considering whether allowing the claim would undermine the integrity of the legal system, whether denying the claim would be a proportionate response to the illegality, and whether it would act as a deterrent to illegal conduct. The court ruled that claims should be dismissed only if it would be contrary to the public interest to allow recovery.

Ashton v Turner (1981)

In this case, the claimant was injured in a car accident while attempting to flee from a crime scene. The court denied the claim, applying the defence of illegality, as the injury arose directly from the claimant's illegal conduct.

Examples

Example 1 - Illegality in Drug-Related Claims

Scenario:

A person involved in the illegal sale of drugs is injured during a transaction. They attempt to claim compensation for their injuries. The court may apply the defence of illegality, preventing recovery, as the harm resulted from the claimant's participation in criminal activity.

Example 2 - Illegality in Unlawful Employment

Scenario:

An individual working without proper authorization is injured on the job. They seek compensation for their injuries. If the employment was illegal due to lack of work permits, the employer may invoke the defence of illegality, arguing that the claim arises from the claimant's unlawful employment status.

Conclusion

The defence of illegality in tort law serves to prevent claimants from profiting from their illegal or immoral actions. It reinforces the principle that courts should not assist in rewarding wrongdoing. While the application of this defence must be carefully considered to ensure fairness and justice, it remains a crucial mechanism for maintaining the integrity of the legal system. Understanding the nuances of the illegality defence helps navigate complex cases where legal and moral issues intersect.
