Criminal Law Flashcards
Goals of criminal law
- Punishment
- Incapacitation
- Deterence
- Rehabilitation
Evidential burden
Applies to certain defences e.g. self-defence
If the defence raised the issue of self-defence and provides sufficient evidence the prosecution has the burden of disproving it
When is the burden of proof is on the defence?
When they defendant raises certain defences:
- Insanity
- Diminished responsibility
Burden of proof is on the balance of probabilities
Actus reus
Actus reus
Physical element of offence (the act)
Mens rea
Mental element of offence
Actus reus and mens rea must occur at the same time
Strict liability offences
No mens rea requirement
Offence committed if actus reus is complete
Actus reus + mens rea - defences = guilt
Elements of liability: actus reus
Conduct (always)
- Acts and behaviour
- Omissions: breach of duty to act
Circumstance (doesn’t apply to all offences)
Outcome (only applies to result crimes)
- Causation must be satisfied (both elements)
a. Factual causation: but for test
b. Legal causation: substantial and operative test
Elements of liability: actus reus - duty to act
- Statute: requires positive action
- Special relationship: parent
- Voluntary assumption of duty of care
- Contract
- Defendant created dangerous situation and is aware of it (two elements)
Elements of liability - actus reus: legal causation
- Substantial: defendant’s conduct was more than minimal
- Operative: no break in chain of causation
Elements of liability - actus reus: break in chain of causation
- Vicitm: if behaviour is so daft as to be unforeseeable - a court will rarely permit the behaviour of a victim to break the chain of causation
- Third party: if act is free, deliberate and informed
- Medical intervention: if so bad and so independent of original injury
No break in chain of causation
- Victim’s pre-existing conditions (thin skull rule)
- Victim’s religious beliefs
Mens rea
State of mind that the defendant must have at the time of committing the actus reus in order to be guilty
Mens rea: intention
- Direct intention: defendant’s aim or purpose
- Indirect intention (oblique intention)
a. Outcome was a virtual certainty (objective)
b. Defendant foresaw that it was a virtual certainty (subjective)
Only available for specific intent offences -where recklessness is not available as a form of men’s rea - it never applies to basic intent offences - only applies when intention is only form of men’s rea available -
Transferred malice
Defendant has mens reas needed for the offence but it is directed at a different victim/item e.g. swing for husband but hit mistress instead
Only applies when the offence committed is of the same type as the one intended
Mens rea: recklessness
- Defendant forsees risk
+ - Under circumstances known to defendant, risk is unreasonable one to take
Indirect intention and recklessness are mutually exclusive
Murder
Causing the death of a human being, unlawfully with intention to kill or cause GBH
- Causing (factual and legal causation)
- Death of human being (feautus not included)
- Unlawful (no legal excuse e.g. killing during war)
- With intention to kill or cause grievous bodily harm
Voluntary manslaughter
Defendant has satisfied the actus reus and mens rea of murder but there is a partial defence:
- Diminshed responsibility
- Loss of control
Voluntary manslaughter: diminished responsibility
- Abnormality of mental functioning (at time of offence)
+ - From recognised medical condition (alcohol dependency, depression and premenstrual stress all accepted)
+ - Abnormality substantially impairs defendant’s ability to:
- Understand their conduct OR
- Form a rational judgement OR
- Exercise self-control
+ - Abnormality explains killing
Burden of proof on defendant on the balance of probabilities
- Defendant is unable to restrain themselves
+ - Caused by qualifying trigger
- Fear of serious violence (to defendant)
OR
- Things said or done which constitute circumstances of extremely grave character giving defendant a justifiable sense of being seriously wronged
- Hypothetical person of the defendant’s age and sex might have reacted the same way
Loss of control MUST be disproved by prosecution beyond reasonable doubt
Involuntary mansalughter
Defendant does not intend to kill or cause GBH
Two types:
1. Unlawful act manslaughter:
2. Gross negligence manslaughter
Involuntary manslaughter: unlawful act manslaughter
Defendant commits some kind of dangerous criminal act which ends up causing victims death
Four parts:
1. Act is intentional
2. Act is unlawful (underlying criminal offence e.g. battery)
3. Act is dangerous (some harm)
4. Causation (factual and legal)
Involuntary manslaughter: gross negligence manslaughter
- Duty of care
+ - Breach of duty of care
+ - Causation (factual and legal)
+ - Serious risk of death (not just harm)
+ - Breach amounts to gross negligence
Assault
- Intentionally OR recklessly (mens rea)
- Causing another person to apprehend (a belief rather than a fear)
- Immediate unlawful violence
Words alone are enough for assault BUT words can be used to negate assault
