Criminal Law Quiz

Criminal liability generally requires both actus reus (a guilty act) and mens rea (a guilty mind). The prosecution bears the burden of proof beyond reasonable doubt. Liability may arise from conduct crimes or result crimes, and must be voluntary.

Theories of criminal law include retribution, deterrence, rehabilitation, and incapacitation. Retribution focuses on punishment, while deterrence aims to prevent crime. Rehabilitation seeks reform, and incapacitation protects society.

Actus reus refers to the physical element of a crime. It may involve conduct, consequences, or circumstances. Omissions can constitute actus reus where there is a duty to act. Acts must be voluntary; involuntary acts do not attract liability.

Causation requires both factual causation (‘but for’ test) and legal causation. The defendant must be a substantial and operating cause of harm. Novus actus interveniens may break the chain of causation if it is sufficiently independent.

Mens rea includes intention, where the defendant aims to bring about a result, and recklessness, where the defendant foresees a risk and takes it. Negligence involves failure to meet a standard of care. Strict liability offences require no mens rea.

Transferred malice applies where intent is transferred from the intended victim to the actual victim. Coincidence requires actus reus and mens rea to occur at the same time, though courts may apply a continuing act doctrine.

Murder is the unlawful killing of a human being under the Queen’s peace with malice aforethought, meaning intention to kill or cause grievous bodily harm. Both actus reus and mens rea must be proven.

Partial defences under the Coroners and Justice Act 2009 reduce murder to voluntary manslaughter. Loss of control requires a qualifying trigger and loss of self-control. Diminished responsibility requires an abnormality of mental functioning.

Unlawful act manslaughter requires a dangerous unlawful act causing death. Gross negligence manslaughter arises where a duty of care is breached in a grossly negligent way, causing death.

Non-fatal offences include assault and battery under the Criminal Justice Act 1988, and more serious offences under the Offences Against the Person Act 1861. These include ABH, GBH, and wounding, with varying levels of harm and mens rea.

Theft under the Theft Act 1968 requires appropriation of property belonging to another, dishonestly, with intention to permanently deprive. Each element must be satisfied.

Robbery involves theft accompanied by force or threat of force. Burglary under s9(1)(a) involves entry with intent to commit a crime, while s9(1)(b) involves committing or attempting theft or GBH after entry.

Insanity applies where the defendant suffers from a defect of reason. Automatism involves involuntary actions. Intoxication may be voluntary or involuntary, affecting liability depending on the crime’s mens rea.

Self-defence allows reasonable force to protect oneself. Duress involves threats of death or serious injury. Necessity applies in limited circumstances. Consent may negate liability in some offences but is restricted in serious harm cases.

Attempts occur where a defendant takes more than merely preparatory steps towards committing a crime with intent. Impossibility is not a defence if the defendant believed the crime was possible.
