AQA A-Level Law: General Elements of Criminal Liability — Revision Notes

Condensed for the final weeks. For the full explanation, use the General Elements of Liability study guide.

The two building blocks

Most crimes need actus reus (guilty act) and mens rea (guilty mind) present at the same time — the “coincidence” requirement, and a favourite application point when the two occur at different moments.

Actus reus — four elements

Element	What it means
Conduct	Acts (positive conduct), omissions (failure to act, only where the law recognises a duty to act) and states of affairs (simply being in a situation satisfies actus reus)
Voluntariness and involuntariness	Liability generally requires voluntary conduct; an involuntary act does not satisfy actus reus
Causation	Conduct must be both factual and legal cause of the consequence
Consequences	Where the offence is defined by its result, that result must actually follow from the defendant’s conduct

Causation test: “but for” the defendant’s act, would the consequence have occurred? (factual) — plus a separate legal-cause test.

Mens rea — three levels of fault, plus one exception

• Intention — aim/purpose; a jury may, but need not, also find intention where the defendant foresaw a consequence as virtually certain.
• Subjective recklessness — the defendant personally foresaw a risk and unreasonably took it anyway.
• Negligence — judged against an objective reasonable-person standard, not the defendant’s own state of mind.
• Strict liability — the specification’s own named exception: no mens rea needed for at least one element.

Transferred malice

Mens rea aimed at intended victim A can transfer to actual victim B — but only if B suffers the same type of harm A was meant to suffer.

Worked example

Defendant punches at A, misses, hits B.

Actus reus:   the punch (act) caused injury (consequence) to B
Mens rea:     intended towards A, not B
Doctrine:     transferred malice — mens rea transfers from A to B
              because the harm to B is the same type as intended for A
Conclusion:   defendant liable for the offence against B

Always work actus reus → mens rea → doctrine → conclusion, in that order — this is the structure AQA mark schemes reward.

Omissions: when does a duty to act arise?

Because criminal law generally does not punish a failure to act, omissions liability depends on proving a recognised duty to act first. The specification’s general elements content requires you to recognise that such duties can arise from, for example, a contractual obligation, a special relationship (such as parent and child), a voluntary assumption of responsibility for another person, or a statutory duty. Without identifying which duty applies, an omissions-based scenario answer cannot proceed to actus reus at all — this is the step examiners most often find missing.

Comparing the fault elements side by side

Fault element	Test	Standard
Intention	Aim/purpose, or foresight of virtual certainty	Subjective
Subjective recklessness	Personally foresaw the risk, unreasonably took it anyway	Subjective
Negligence	Fell below the standard of a reasonable person	Objective
Strict liability	No mens rea required for at least one element	None

Keep “subjective” (about this defendant’s actual state of mind) and “objective” (about what a reasonable person would have done) clearly separate — confusing the two is one of the most common ways a Law essay loses marks on this content, since intention and recklessness require evidence of the defendant’s own mind, while negligence does not.

Exam traps

• Assuming every offence needs mens rea — strict liability is the specification’s own named exception.
• Confusing intention (aim/virtual certainty) with subjective recklessness (foresaw a risk, took it anyway) — these are different, gradated fault levels.
• Applying transferred malice where the actual harm is a different type from what was intended — the doctrine does not apply then.
• Forgetting the coincidence requirement when actus reus and mens rea occur at different times in a scenario.

Building a scenario answer

Scenario questions on this content reward a consistent structure: identify the actus reus first (what is the conduct — an act, an omission or a state of affairs — was it voluntary, did it cause the consequence, and did the required consequence follow?), then identify the mens rea (intention, subjective recklessness, negligence, or strict liability), then check the coincidence requirement, then apply any relevant doctrine such as transferred malice. Working through the elements in this fixed order, rather than jumping straight to a conclusion about guilt, is what AQA’s law mark schemes reward at the higher bands — the reasoning process is assessed, not just the final answer.

A final practical tip: in a timed answer, briefly label each element as you address it (Actus reus: …, Mens rea: …, Doctrine: …, Conclusion: …) rather than writing continuous prose that blurs the boundaries — examiners marking against a levels-based scheme find it far easier to award marks for each element when the structure is visibly signposted.

Self-test

1. State the “but for” test and what it establishes.
2. Distinguish intention from subjective recklessness.
3. What condition must be met for transferred malice to apply?
4. Name the specification’s own exception to the general mens rea requirement.
5. Why does “state of affairs” differ from an ordinary “act”?

Answers: 1. But for the defendant’s act, would the consequence have occurred? — it establishes factual causation. 2. Intention is the defendant’s aim or purpose (or foreseeing a consequence as virtually certain); subjective recklessness is personally foreseeing a risk and unreasonably taking it anyway — a lower level of fault. 3. The harm actually caused to the unintended victim must be the same type of harm intended for the original victim. 4. Strict liability. 5. A “state of affairs” offence can be satisfied simply by being in a certain situation, regardless of any voluntary conduct, unlike an ordinary act which requires positive, voluntary conduct.
