Welcome to the World of False Imprisonment!

Imagine you are sitting in a classroom and someone locks the door from the outside. You can’t leave, and there is no other way out. Even if you aren't physically touched, your freedom to move has been taken away. In the law of tort, this is known as False Imprisonment.

In these notes, we will break down what makes a situation "False Imprisonment," what the law requires to prove it, and when someone might actually have a legal right to stop you from moving. This chapter is part of the "Trespass to the Person" family, alongside Assault and Battery.

Quick Note: False imprisonment is actionable per se. This is a fancy legal term that means you don't have to prove you were hurt or lost money to sue. The fact that your liberty was taken away is enough for the law to step in.


1. What is False Imprisonment?

False imprisonment is defined as the intentional and total restraint of a person’s liberty, without lawful justification, by another person.

To understand this, we look at three main ingredients (or "elements"):

1. The restraint must be total (not just a partial block).
2. The act must be intentional and direct.
3. There must be no lawful authority for the restraint.

The Formula for False Imprisonment:

\( Total\ Restraint + Intentional/Direct\ Act + No\ Lawful\ Justification = False\ Imprisonment \)


2. The "Total Restraint" Rule

This is the most important part of this tort. For it to be false imprisonment, the person must be blocked in every direction. If there is a reasonable way to escape, it is not false imprisonment.

The Bridge Analogy:
Imagine you are walking across a bridge. A police officer blocks your path and tells you that you cannot go forward, but you are free to turn around and walk back the way you came. Is this false imprisonment?
No. Because you still have a way out (backwards), your restraint is not total. This was the decision in the famous case of Bird v Jones (1845).

What is a "Reasonable" Escape?
A way out isn't "reasonable" if it involves jumping out of a third-story window or swimming across a dangerous river. If the only way out is dangerous, the law will still count the restraint as total.

Key Takeaway: If you can't go north, but you can go south, east, or west, you aren't "imprisoned" in the eyes of the law.


3. Do You Need to Know You Are Imprisoned?

This is a tricky question that often confuses students! Can you be falsely imprisoned if you are asleep, or if you are so drunk that you don't realize the door is locked?

The Answer is Yes.
The law protects your right to liberty, even if you aren't aware that it’s being taken away at that exact moment.

Example: If a person is locked in a room while they are unconscious, and the door is unlocked before they wake up, they have still been falsely imprisoned. This principle was established in cases like Meering v Grahame-White Aviation (1919) and confirmed in Murray v Ministry of Defence (1988).

Don't worry if this seems strange! Just remember: You don't need to feel "trapped" or be upset to have a claim. The focus is on the fact that your freedom was taken away, not on your feelings about it.


4. Intentional and Direct

Like Assault and Battery, False Imprisonment must be a direct result of the defendant's actions. It cannot be an accident.

Example: If a shopkeeper accidentally locks the store at night without knowing you are still inside the changing room, that is usually negligence, not the tort of False Imprisonment. To be liable for this tort, the defendant must have intended to confine you or been "reckless" about it.


5. Lawful Restraint (When is it NOT False Imprisonment?)

Sometimes, locking someone up or stopping them from moving is perfectly legal. These are the defences to the tort.

A. Lawful Arrest

The police have the power to arrest people under the Police and Criminal Evidence Act (PACE) 1984. If a police officer (or sometimes a private citizen) follows the correct legal procedures for an arrest, the restraint is "lawful" and cannot be sued as false imprisonment.

B. Consent (Volenti)

If you agree to be in a situation where your movement is restricted, you cannot later complain.
Example: If you get on a non-stop train from London to Manchester, you are "trapped" on that train for two hours. However, you consented to this by buying a ticket and getting on the train. You cannot sue the train company for false imprisonment during the journey!

C. Necessity

If someone is restrained to prevent a greater harm (like stopping someone from walking into a burning building or preventing a person from hurting themselves during a medical emergency), the court may find the restraint was "necessary."

D. Conditions of Entry

If you enter someone's property, they can set reasonable conditions for how you leave.
Example: A miner goes down into a mine. He then decides he wants to leave early, but the lift only runs at set times. The mine owners aren't falsely imprisoning him by making him wait for the scheduled lift, because he entered the mine knowing the rules of how the "exit" worked.


Quick Review: Check Your Knowledge

  • Is it total? If there's a safe way out, it’s not false imprisonment.
  • Does the victim need to know? No, they can be asleep or unaware.
  • Is it an accident? No, it must be intentional or direct.
  • Is there a reason? If the police have a valid warrant or PACE power, it’s lawful.

Common Mistake to Avoid: Many students think false imprisonment requires a "prison" or a "locked room." It doesn't! It can happen in an open street if a group of people surround you so that you cannot move in any direction.


Summary Table

Element Requirement
Nature of Tort Actionable per se (no physical harm needed).
Restraint Must be total. Partial obstruction is not enough.
Knowledge The victim does not need to be aware of the restraint at the time.
Authority Must be unlawful. (Police arrests under PACE are lawful).
