Tort is a civil wrong arising from an act or failure to act that causes personal injury or property damage. It is defined as a wrong under common law for which damages can be claimed, excluding breaches of contract. The word tort comes from the Latin word "tortum" meaning twisted. It was introduced to the Indian legal system through British rule. For a case of nervous shock, the plaintiff must prove proximity to the incident, shock from seeing or hearing it, and that it caused a recognized psychiatric illness. The defendant is only liable for foreseeable harms to those in the danger zone, not mere bystanders outside it.
