What was the outcome in the case of Impress Ltd v. Rees (1971)?

In the case of Impress Ltd v. Rees (1971), the outcome was that the company was not held liable due to the actions of a third party, specifically because tampering had occurred. The court found that the pollution that led to the claim against Impress Ltd was not directly caused by the company's actions, but rather was the result of interference by an external person who had tampered with the equipment in question. This distinction is crucial in tort law, as liability often hinges on the direct causation of the harm by the defendant's actions versus the actions of intervening parties. In this case, the court's decision underscored the importance of establishing a clear link between the defendant's conduct and the alleged damages, indicating that liability would not extend to situations where third-party actions disrupt that connection.
