Top 10 English Criminal Law Cases

English criminal law has developed through landmark judicial decisions that establish the principles governing criminal liability, criminal defences and the mental elements of offences. These cases are important for understanding how the courts interpret the actus reus, mens rea, intention, recklessness and other fundamental concepts of criminal law. We have selected 10 most important English criminal law cases that every common law student should know.

1. R v Dudley and Stephens (1884)

This case established that necessity is not a defence to murder. The defendants were shipwrecked at sea with two other crew members. After spending several days without food, they killed and ate a young cabin boy to survive. They argued that killing the boy was necessary to save their own lives.

The court rejected the defence of necessity and held that the defendants were guilty of murder. A person cannot deliberately kill an innocent person simply to preserve his own life. The case remains an important authority on the limits of the defence of necessity in criminal law.

2. Fagan v Metropolitan Police Commissioner (1969)

This case established that an act can become a continuing act, satisfying the actus reus requirement of a criminal offence. The defendant accidentally drove his car onto a police officer's foot. When the officer asked him to move the vehicle, the defendant refused and deliberately kept it there.

The court held that although the initial contact was accidental, the defendant's subsequent decision to leave the car on the officer's foot constituted a continuing act accompanied by the necessary mens rea. The case illustrates the relationship between actus reus and mens rea and demonstrates that they must coincide.

3. R v Jogee (2016)

This case clarified the law on joint enterprise and secondary liability. The defendant and another man were involved in an incident during which the other man fatally stabbed a victim. The prosecution relied on the defendant's participation and foresight that violence might occur to establish his liability as a secondary party.

The Supreme Court held that foresight that the principal might commit an offence is evidence from which intention may be inferred, but it is not itself the legal test for secondary liability. The prosecution must establish that the defendant intentionally assisted or encouraged the commission of the offence. The case corrected the previous approach to joint enterprise and clarified the distinction between foresight and intention.

4. M’Naghten’s Case (1843)

This case established the legal test for the defence of insanity. The defendant suffered from a delusion that led him to shoot and kill Edward Drummond, believing that he was targeting the Prime Minister, Sir Robert Peel.

The House of Lords established the M’Naghten Rules, which provide that a person may be found not guilty by reason of insanity if, at the time of the offence, he was suffering from a defect of reason caused by a disease of the mind, such that he either did not know the nature and quality of his act or did not know that what he was doing was wrong. The M’Naghten Rules remain the foundation of the insanity defence in English criminal law.

5. R v Cunningham (1957)

This case established the meaning of subjective recklessness in criminal law. The defendant removed a gas meter from a wall to steal money from it. As a result, gas escaped into a neighbouring property and endangered another person.

The court held that recklessness required the defendant to have foreseen the risk of harm and nevertheless taken it. The defendant had to be aware of the possibility of the relevant consequence. The case established the subjective approach to recklessness, under which the defendant's actual awareness of the risk is relevant.

6. R v Woollin (1999)

This case established the direction that a jury may use when determining oblique intention. The defendant threw his three-month-old baby towards a hard surface during an incident in which the child was crying. The baby suffered fatal injuries.

The House of Lords held that a jury may find intention where death or serious bodily harm was a virtual certainty as a result of the defendant's actions, and the defendant appreciated that this was the case. The case provides an important direction for establishing intention where causing death or serious injury was not the defendant's direct purpose.

7. R v G (2003)

This case established the modern subjective test for recklessness. Two young boys, aged 11 and 12, set fire to newspapers outside a shop. They left the scene without extinguishing the fire, which spread and caused substantial damage to the building.

The House of Lords rejected the previous objective approach to recklessness established in R v Caldwell (1982). It held that a person is reckless where he is aware of a risk that a circumstance exists or a result will occur and, in the circumstances known to him, it is unreasonable to take that risk. The case restored the subjective approach to recklessness and remains the leading authority on the modern test.

8. R v Brown (1993)

This case established that consent is generally no defence to the intentional infliction of actual bodily harm or more serious injury, unless the conduct falls within a recognised exception. The defendants were involved in consensual sadomasochistic activities that caused actual bodily harm. They argued that the participants had consented to the injuries and that no criminal offence had been committed.

The House of Lords rejected the argument and held that consent was not a defence to the infliction of actual bodily harm in these circumstances. The case remains an important authority on the limits of consent as a defence to non-fatal offences against the person.

9. R v Church (1966)

This case established the test for unlawful act manslaughter. The defendant assaulted a woman, believing that he had killed her. He threw her body into a river, where she drowned. It later emerged that she had been unconscious rather than dead when he threw her into the water.

The Court of Appeal held that unlawful act manslaughter requires an unlawful act that is objectively dangerous, meaning that all sober and reasonable people would recognise that the act exposed another person to the risk of some physical harm. The case remains a leading authority on the objective dangerousness requirement for unlawful act manslaughter.

10. R v Miller (1983)

This case established that a person who creates a dangerous situation may incur criminal liability by failing to take reasonable steps to prevent harm. The defendant accidentally started a fire while smoking in a building. After noticing that his mattress was on fire, he moved to another room rather than taking steps to extinguish the fire or prevent it from spreading.

The House of Lords held that a person who creates a dangerous situation may come under a duty to take reasonable steps to prevent or minimise the resulting danger. His failure to act could therefore constitute the actus reus of a criminal offence. The case is an important authority on omissions and the circumstances in which criminal liability may arise from a failure to act.
