Revise Battery for Cambridge 9084 (4.3.2)

The tort of battery is defined as the direct and intentional application of unlawful force to another person. This classic definition, articulated by Goff LJ in Collins v Wilcock, establishes battery as a form of trespass to the person. Its primary purpose is to protect an individual's bodily integrity and personal space from unwanted physical interference. Crucially, battery is actionable per se, which means a claimant does not need to prove they have suffered any injury or financial loss. The mere fact that unlawful contact occurred is sufficient to establish the tort. This distinguishes it from negligence, where proof of damage is an essential element. The three core elements that a claimant must prove are that the force was direct, intentional, and unlawful.

The element of 'force' in battery does not require violence, injury, or aggression. As established in Cole v Turner, "the least touching of another in anger is a battery." The modern interpretation has moved away from requiring 'anger', focusing instead on whether the contact is hostile or goes beyond what is generally acceptable in the ordinary conduct of daily life. For example, an unwanted kiss (R v Chief Constable of Devon and Cornwall, ex p CEGB), spitting on someone (R v Cotesworth), or even touching a person's clothing while they are wearing it (Pursell v Horn) can constitute a battery. The key is that the contact is non-consensual and exceeds the implied consent for everyday jostlings, as described in Collins v Wilcock.

For a battery to be established, the application of force must be both direct and intentional. 'Direct' means it must follow so immediately upon the defendant's act that it can be seen as part of that act. The courts have interpreted this broadly. In Scott v Shepherd, throwing a lighted squib which was then passed on by others was still considered direct, as the subsequent actions were an inevitable consequence. Similarly, an indirect act like placing acid in a hand-dryer which then injures the next user (DPP v K, a criminal case) illustrates how the chain of events can be seen as direct. The mental element required is the intention to apply force. This was clarified in Letang v Cooper, which held that if the contact is unintentional, the claim must be in negligence, not battery. The defendant must intend the contact, not necessarily the harm that results. Furthermore, the doctrine of transferred malice applies; if a defendant intends to hit A but misses and hits B, the intention is transferred to B (Livingstone v Ministry of Defence).

The final element is that the force must be 'unlawful', meaning it lacks legal justification. If a valid defence exists, the contact is not unlawful, and the claim for battery will fail. The most common defence is consent, which can be express (e.g., in a medical procedure) or implied (e.g., for the ordinary jostlings of a crowded street). For medical consent to be valid, the patient must be informed in broad terms of the nature of the procedure (Chatterton v Gerson). Other complete defences include self-defence, defence of another, and defence of property, provided the force used was reasonable and proportionate to the threat (Lane v Holloway). Necessity may also be a defence in limited circumstances, such as a doctor providing life-saving treatment to an unconscious patient. Finally, lawful authority, such as a police officer making a lawful arrest, provides a justification for the use of reasonable force.
