Trespass to the Person — Assault, Battery, Mayhem & False Imprisonment — Law of Torts Notes

Assault, Battery and Mayhem

At a parish meeting in 1830, a man sitting seven seats away from the chairman grew unruly. When a resolution was passed to eject him, he said he would rather pull the chairman out of his chair, and advanced towards him with clenched fists — only to be stopped by a churchwarden sitting in between. He never touched the chairman. He was still liable, because the tort of assault protects your peace of mind, not merely your body.

Three wrongs to the body

A. Assault.

Assault is an act of the defendant which causes the plaintiff reasonable apprehension of the infliction of immediate, unlawful force upon his person.

Notice what is protected: not the body, but the fear. No contact at all is required.

The essentials:

  1. An apparent present ability to carry out the threat. Pointing an unloaded gun at someone who does not know it is unloaded is assault; the test is what the plaintiff reasonably apprehends.
  2. A reasonable apprehension of immediate force. A threat of future harm — “I will beat you next week” — is not assault.
  3. Intention to create that apprehension.

Mere words were traditionally said not to constitute assault, but words may take away the assault (Tuberville v Savage, 1669 — “if it were not assize time, I would not take such language from you”, said with a hand on a sword hilt, was held not to be an assault because the words negated the threat).

B. Battery.

Battery is the actual application of unlawful force to another person, without lawful justification.

The essentials:

  1. Use of force, however slight. The law does not require injury or even pain — the least touching in anger is a battery.
  2. Without lawful justification — no consent, no self-defence, no lawful authority.
  3. The force may be applied indirectly: pulling away the chair a man is about to sit on, throwing water over him, or setting a dog on him.

Every battery is normally preceded by an assault, but not always — striking a man from behind is battery without assault, because he apprehended nothing.

C. Mayhem.

Mayhem is a battery which causes such bodily harm that the victim’s ability to defend himself is impaired — historically the loss of a limb, an eye, or a finger. It is treated as an aggravated form of battery and attracts heavier damages.

D. All three are actionable per se.

No proof of damage is needed. The violation of the right to personal security is itself the injury — the injuria sine damno principle from Unit 1 at work.

E. The umbrella term: trespass to the person.

Examiners sometimes set the whole head at once — “Explain trespass to the person” (a 16-mark essay in Dec 2015) — and a student who has learnt only the individual torts can be thrown by the phrase. It is simply the collective name for the direct, intentional interferences with the person, and it has three limbs:

  1. Assault — apprehension of immediate unlawful force.
  2. Battery — the actual application of unlawful force.
  3. False imprisonment — total restraint of liberty without lawful justification (Topic 2).

Mayhem is treated as an aggravated battery rather than a fourth limb. All three descend from the old writ of trespass (Unit 1), which is why all three are direct, all three require intention, and all three are actionable per se. If the interference is indirect or careless rather than direct and intentional, the claim lies in negligence, not in trespass — that is the modern dividing line.

So an essay on “trespass to the person” is answered by taking the three limbs in turn with their essentials, cases and defences, and closing with the trespass/negligence distinction.

🧩 WORKED EXAMPLE — the chair pulled away

Facts. Mr A is about to sit down on a chair. Mr B, standing behind him, pulls the chair away, and A falls to the ground.

Rule. Battery is the application of unlawful force to another, and the force may be applied indirectly; no injury need be proved.

Apply. B never touched A’s body — that is the decoy. But he intentionally set in motion the force that brought A to the ground. Indirect application is sufficient, and the absence of serious injury is irrelevant because battery is actionable per se.

Note the limit. If A had seen B reaching for the chair and feared the fall before it happened, there would be an assault as well as a battery.

Conclusion. B is liable for battery.

⚠️ DON’T CONFUSE — assault and battery

Assault = the reasonable apprehension of force; battery = the force itself. Aiming a blow that misses is assault alone. Striking a sleeping man is battery alone. Aiming a blow that lands, in his sight, is both. In ordinary speech “assault” means being hit — in law it means being made to fear being hit.

The two definitions, in summary (not a verbatim quotation): battery is the intentional and direct application of force to another person without lawful justification. Assault: an act which causes another person to apprehend the infliction of immediate, unlawful force on his person.

In Simple Terms: assault frightens; battery touches. The law protects both your body and your sense of physical safety, and it does not wait for you to be injured before it acts.

Case Laws

  • [C-23] Stephens v Myers (1830) — advancing with clenched fists, stopped before reaching the plaintiff; assault.
  • Tuberville v Savage (1669) — words negating the threat; no assault.
  • Bavisetti Venkata Surya Rao v Nandipati Muthayya (1964) — a village officer threatening to seize ornaments for arrears; on the facts, no assault.
  • Cole v Turner (1704) — “the least touching of another in anger is a battery.”

False Imprisonment

In 1845 part of Hammersmith Bridge was closed off for a boat race. A man named Bird insisted on pushing through, and was blocked by policemen — but he was free at all times to turn round and go back the other way. He sued for false imprisonment and lost. Being obstructed in one direction is not imprisonment; you must be hemmed in on every side.

Total restraint without lawful justification

False imprisonment is the total restraint of a person’s liberty, for however short a time, without lawful justification.

Two words carry the whole tort: total, and unlawful.

A. The essentials.

  1. Total restraint of liberty. The restraint must be complete. A partial obstruction leaving a reasonable means of escape is not false imprisonment — Bird v Jones. There need be no physical barrier: a mere assertion of authority to which the plaintiff submits is enough.

  2. Without lawful justification. Lawful arrest, lawful detention under a court’s order, and the exercise of a valid statutory power are all justifications.

B. Two points the problems always test.

  1. Knowledge of the restraint is NOT essential. A person may be falsely imprisoned while asleep, drunk, or unconscious. In Meering v Grahame-White Aviation Co. (1919) the plaintiff, questioned in a room with guards outside of whom he was unaware, was held to have been imprisoned. This is the answer to the sleeping-man problem, where the door is locked and reopened before he wakes. (Contrast the older Herring v Boyle, 1834, which took the opposite view and is no longer followed.)

  2. A reasonable means of escape defeats the claim — but the escape route must be reasonable, not dangerous or degrading. A locked room with an open first-floor window offers no reasonable escape.

C. Detention on a judicial order.

Where a magistrate orders a person into custody, the detention is by the court’s act, not the complainant’s. The complainant may be liable for malicious prosecution (Topic 5), but not for false imprisonment — Austin v Dowling (1870). This distinction decides one of the recurring problems.

D. Remedies.

  1. Damages, including aggravated or exemplary damages for high-handed conduct.
  2. Self-help — the person restrained may use reasonable force to escape.
  3. Habeas corpus — a writ to secure immediate release, and in India, compensation under Arts. 32 and 226 (Bhim Singh, Rudal Shah).

🧩 WORKED EXAMPLE — the sleeping man

Facts. Shyam is fast asleep in a room. Prem closes and locks the door from outside, and opens it again before Shyam wakes. Shyam never knew.

Rule. Knowledge of the restraint is not an essential of false imprisonment (Meering v Grahame-White).

Apply. For the period the door was locked, Shyam’s liberty was totally restrained without lawful justification. His ignorance of the fact does not undo the restraint; the tort protects the liberty itself, not the consciousness of losing it.

Decoy. The words “before Shyam wakes”, inviting the conclusion that no harm was done.

Note the limit. Damages will be nominal, since he suffered no distress — but the tort is complete and actionable per se.

Conclusion. Prem is liable; damages nominal.

Coleridge J in Bird v Jones (1845): “A prison may have its boundary large or narrow, visible and tangible… but a boundary it must have; and that boundary the party imprisoned must be prevented from passing… some boundary set to the will, some restraint upon the locomotive power.”

In Simple Terms: imprisonment means being shut in on every side. If you can still walk away in some reasonable direction, you have been obstructed, not imprisoned.
