Criminal Law In Common Law Countries
What is Common Law
Common law is a legal system characterized by the reliance on judicial precedents (case law) and customs rather than codified statutes alone. It originated in England and is the foundation of the legal systems in countries like the United States, Canada, Australia, and others.
Criminal Law in Common Law Systems
Adversarial system: The prosecution and defense present cases before an impartial judge or jury.
Role of Precedent: Court decisions interpret and develop the principles of criminal law.
Statutory Law: Legislatures enact criminal statutes, but courts interpret them and fill gaps.
Elements of Crime: The prosecution must prove actus reus (guilty act) and mens rea (guilty mind).
Presumption of Innocence: The accused is presumed innocent until proven guilty beyond reasonable doubt.
Key Features of Criminal Law in Common Law Countries
Hierarchy of Courts: Higher courts set binding precedents for lower courts.
Doctrine of Stare Decisis: Courts follow precedents unless overturned or distinguished.
Trial by Jury: Frequently used for serious offenses.
Punishments: Range from fines and imprisonment to capital punishment (depending on jurisdiction).
Rights of the Accused: Include the right to counsel, protection against self-incrimination, and fair trial.
Important Case Laws in Criminal Law (Common Law Jurisdictions)
1. R v. Cunningham (1957) 2 QB 396 (England)
Facts:
The defendant tore a gas meter from the wall to steal money, causing gas to leak and endanger a neighbor’s life.
Issue:
Whether Cunningham had the necessary mens rea (malice or recklessness) for the offense of maliciously administering a noxious thing.
Judgment:
The court clarified that malice includes either intention or recklessness.
Recklessness means the defendant foresaw the risk and still proceeded.
Cunningham’s conviction was quashed because there was no proof he foresaw the risk.
Significance:
Established the modern test for recklessness in criminal law.
Distinguishes between subjective and objective recklessness.
Important precedent for interpreting mens rea.
2. R v. Brown (1993) 2 All ER 75 (UK House of Lords)
Facts:
A group of consenting adult men engaged in sadomasochistic acts, some causing injuries. They were charged with assault occasioning actual bodily harm.
Issue:
Whether consent is a defense to charges of bodily harm in consensual activities.
Judgment:
The court held that consent is not a valid defense to actual bodily harm in sadomasochistic activities.
Public policy interests outweighed personal autonomy.
The defendants’ convictions were upheld.
Significance:
Landmark case on limits of consent in criminal law.
Highlights the role of public morality and policy in criminal justice.
Influences cases involving bodily harm and consent.
3. R v. Dudley and Stephens (1884) 14 QBD 273 DC (England)
Facts:
Shipwrecked sailors killed and ate a cabin boy to survive.
Issue:
Whether necessity (survival) is a defense to murder.
Judgment:
The court ruled that necessity is not a defense to a charge of murder.
The defendants were found guilty despite the circumstances.
The law does not permit killing an innocent person even to save one’s own life.
Significance:
Established that necessity cannot justify murder.
Important for the doctrine of necessity in criminal law.
Widely cited in discussions on moral and legal limits.
4. M'Naghten’s Case (1843) 10 Cl & F 200 (UK)
Facts:
Daniel M’Naghten, suffering from a mental illness, killed the secretary of the British Prime Minister, mistakenly believing he was persecuted.
Issue:
Legal standard for insanity as a defense.
Judgment:
Established the “M’Naghten Rules” for insanity.
A defendant is insane if, at the time of the act, they were laboring under such a defect of reason from disease of the mind that they did not know the nature or quality of the act, or if they did, they did not know it was wrong.
M’Naghten was acquitted on grounds of insanity.
Significance:
Foundation of the insanity defense in common law jurisdictions.
Defines cognitive incapacity and moral awareness for criminal responsibility.
5. R v. Woollin [1999] 1 AC 82 (UK House of Lords)
Facts:
Defendant threw his baby onto a hard surface, resulting in death. The defendant denied intent to kill.
Issue:
Definition of intention in homicide cases.
Judgment:
The court refined the test for indirect intention.
Held that if death or serious injury is a virtually certain consequence of the defendant’s actions and the defendant appreciated this, intent may be inferred.
Conviction was upheld under this test.
Significance:
Clarified the concept of oblique intention.
Influential in determining mens rea in homicide cases.
