3.2 - Mens rea, strict liability and coincidence

Fault And The Criminal Liability Question

Most criminal offences in England and Wales require both an external element and a fault element. The external element is the actus reus: conduct, an omission where there is a duty to act, a state of affairs, causation or a consequence. The fault element is usually mens rea: the defendant's mental state in relation to the actus reus.

AQA places this topic inside the general elements of criminal liability. The specification names:

The core legal question is: what fault, if any, must the prosecution prove for this offence or element? That question controls liability. If the offence requires intention, recklessness will not be enough. If it requires subjective recklessness, mere carelessness will not be enough. If the offence is strict liability for a particular element, the prosecution does not need to prove mens rea for that element, although it must still prove the actus reus and any other required elements.

Fault also matters for criminal theory. AQA links criminal law to autonomy, fault and individual responsibility. Criminal punishment is easier to justify when the defendant chose, intended, foresaw or culpably risked wrongdoing. It is harder to justify where liability is imposed despite the defendant taking care. This is why fault links directly to the principles of correspondence and fair labelling: the defendant's liability and label should not normally exceed the harm and risk covered by their fault.

Do not treat mens rea as a loose word for "bad behaviour". In an answer, identify the precise form of fault and attach it to the exact actus reus element: intention to cause serious harm, recklessness as to applying unlawful force, dishonesty and intention to permanently deprive, or negligence gross enough for criminal liability. The stronger answer is the one that asks, element by element, what the defendant knew, intended, foresaw or failed to do.

Intention: Direct And Oblique

Intention is the highest ordinary level of mens rea. It is subjective: the court is concerned with the defendant's actual state of mind, inferred from words, conduct and surrounding facts. Intention is especially important in murder and serious non-fatal offences, where the difference between intention and recklessness can decide the offence charged and the seriousness of liability.

R v Mohan is commonly used for the idea that intention involves a decision to bring about the prohibited consequence, so far as it lies within D's power. D does not have to desire the consequence in a moral or emotional sense. A defendant may directly intend a result because it is the means to another end.

Oblique intention deals with cases where the prohibited consequence is not D's aim, but is so closely connected to it that the law may allow a jury to find intention. The practical test from R v Woollin is that the result must be a virtual certainty from D's act and D must appreciate that it is a virtual certainty. Matthews and Alleyne is a useful caution: foresight of a consequence is evidence from which intention may be found; it is not automatically the same as intention.

Use this operational test:

The facts matter. A planned attack with a targeted blow to a vulnerable part of the body may support direct intention to cause serious harm. A less targeted act may still support oblique intention if the serious consequence was virtually certain and D appreciated that. But where D merely foresaw a risk, the correct category is usually subjective recklessness, not intention.

AQA examiners have warned students not to confuse different cases called Cunningham. Cunningham (1957) is about recklessness. It is not authority for intention to cause serious harm in murder. When the issue is intention, use intention authorities such as Mohan, Woollin and Matthews and Alleyne.

Recklessness And Negligence

Subjective recklessness is a lower level of fault than intention but still requires an actual state of mind.

R v Cunningham (1957) is the core authority for this subjective idea of recklessness.

For AQA purposes, the key is to attach recklessness to the correct actus reus element. In assault or battery, for example, the issue is whether D intended or was reckless as to causing apprehension of immediate unlawful force or applying unlawful force. In unlawful act manslaughter, the underlying unlawful act normally needs its own mens rea, often intention or subjective recklessness as to that act.

Negligence is different.

In criminal law, ordinary carelessness is not automatically enough. Where negligence becomes the basis of serious criminal liability, such as gross negligence manslaughter, the breach must cross a demanding threshold. R v Adomako is used for gross negligence manslaughter: the conduct must be so bad in all the circumstances that it should be judged criminal. AQA materials also refer to the need for the breach to be truly exceptionally bad and reprehensible in later gross negligence cases such as Sellu and Bawa-Garba.

The distinction is exam-important:

This matters because a person who fails to notice an obvious risk may be negligent but not subjectively reckless. Conversely, a person who notices even a small but relevant risk and goes ahead may be reckless, even if they hoped the harm would not happen.

When applying recklessness, use the facts to prove awareness. Statements, warnings, previous events, visible danger, repeated behaviour and D's attempts to avoid detection may all support an inference that D foresaw the risk. When applying negligence, use the facts to prove the standard and the breach: what a reasonable person or professional would have done, how obvious and serious the risk was, and whether the failure was merely careless or grossly bad.

Transferred Malice

Transferred malice deals with a mismatch between the intended victim and the actual victim. If D has the mens rea for an offence against V1 but accidentally causes the same type of harm to V2, the mens rea can transfer from V1 to V2. The label "malice" is old language: in this topic it means the required mens rea, not spite or hatred.

R v Latimer is the standard authority. D aimed a blow at one person but injured another. The mens rea directed at the intended victim could be transferred to the actual victim because the same kind of unlawful personal injury occurred. AQA Paper 1 materials regularly credit accurate use of Latimer where an intended attack misses one victim and injures another.

Use this operational structure:

The common confusion is to use transferred malice whenever a different person is harmed. That is too broad. If D intended to damage property but accidentally injured a person, the mens rea for property damage does not simply become mens rea for personal injury. If D intended only minor harm, that intention will not automatically satisfy an offence requiring intention to cause serious harm. The transferred mens rea must match the offence being considered.
