patient. Similarly, a battery occurs if the surgeon allows a cousin who is a plumber with no medical training to help fish out the appendix during the surgery. Although the patient has consented to being touched by the surgeon, this consent does not extend to people who the patient would not reasonably anticipate would be participating in the procedure. The battery may occur even if the victim is unaware of the contact at the time and the defendant is nowhere near the scene at the time of the contact. If a tortfeasor puts an offensive substance in another person's food, and the other person consumes the offensive substance, the battery has been committed even if the victim is not made aware that they have eaten something offensive until much later. Battery by country United States In the United States, the common law requires the contact for battery be "harmful or offensive." The offensiveness is measured against a reasonable person standard. Looking at a contact objectively, as a reasonable person would see it, would this contact be offensive? Thus, a hypersensitive person would fail on a battery action if jostled by fellow passengers on a subway, as this contact is expected in normal society and a reasonable person would not find it offensive. Harmful is defined by any physical damage to the body. Because courts have recognized a cause of action for battery in the absence of body-to-body contact, the outer limits of the tort can often be hard to define. The Pennsylvania Superior Court attempted to provide some guidance in this regard in Herr v. Booten by stressing the importance of the concept of one's personal dignity. In that case, college students purchased and provided their friend with alcohol on the eve of his twenty-first birthday. After drinking nearly an entire bottle of Jack Daniels whiskey, the underage man died of acute ethanol poisoning. Reversing the decision of the trial court, the Pennsylvania Superior Court held that supplying a minor with alcoholic beverages, while certainly constituting a negligent act, did not rise to the level of a battery. In the words of Judge Montemuro, supplying a person with alcohol "is not an act which impinges upon that individual's sense of physical dignity or inviolability." England and Wales Following UK Tort law the tort of battery is where the defendant intentionally, or recklessly, and unlawfully makes direct contact with the claimant.
