AQA A-Level Law: General Elements of Criminal Liability (7162)

This guide covers General Elements of Liability, part of Section 3.2: Criminal Law in AQA A-level Law (7162), A-level exams June 2019 onwards, Version 1.1. This content underpins every specific criminal offence studied later in the section.

Where this fits

Section 3.2 Criminal Law opens with the rules and theory of criminal law, before this content establishes the general building blocks — actus reus and mens rea — that apply across virtually every criminal offence covered later, including fatal and non-fatal offences against the person.

Syllabus coverage

AQA A-LEVEL LAW (7162) — GENERAL ELEMENTS OF LIABILITY

Actus reus: conduct; acts and omissions and state of affairs; voluntariness and involuntariness; causation; consequences. Additional fault elements: mens rea (intention and subjective recklessness); negligence; transferred malice. No fault: strict liability. Coincidence of actus reus and mens rea.

How to approach it

Build your understanding around the core principle that most criminal offences require both actus reus (the guilty act) and mens rea (the guilty mind) to be present at the same time — this is what “coincidence of actus reus and mens rea” refers to, and it’s a frequently tested application point when a defendant’s guilty state of mind occurs at a different moment from their guilty act.

For actus reus, keep the specification’s named categories distinct: most offences require a positive act, but some can be committed by an omission (a failure to act) where the law recognises a duty to act; “state of affairs” offences are a narrower category where simply being in a certain situation (regardless of voluntary conduct) can satisfy actus reus. Causation is its own sub-skill — the prosecution must prove the defendant’s conduct was both the factual cause (using the “but for” test: but for the defendant’s act, would the consequence have occurred?) and the legal cause of the prohibited consequence.

For mens rea, distinguish intention (the defendant’s aim or purpose, or foreseeing a consequence as virtually certain) from subjective recklessness (the defendant personally foresaw a risk and unreasonably took it anyway) — these represent different, gradated levels of culpability. Negligence is a lower fault standard again, judged against an objective reasonable-person standard rather than the defendant’s own state of mind. Transferred malice allows mens rea to “transfer” from an intended victim to an actual, unintended victim of the same type of harm. Strict liability offences, by contrast, require no proof of mens rea for at least one element of the offence — know that this is the specification’s own named exception to the general actus reus/mens rea requirement.

Worked example: applying transferred malice

A defendant throws a punch intending to hit person A, but misses and instead hits person B, injuring them. Explain how the defendant can still be criminally liable for the injury to B.

Actus reus:        the defendant's act (throwing a punch) caused a
                    prohibited consequence (injury) to B
Mens rea:           the defendant intended to cause harm, but to A,
                    not B
Doctrine applied:   transferred malice allows the mens rea the
                    defendant held towards A to transfer to the actual
                    victim, B, provided the harm caused to B is the
                    same type of harm the defendant intended for A
Conclusion:         the defendant can be liable for the offence
                    against B, because the law treats the mens rea as
                    satisfied for the actual victim through the
                    transferred malice doctrine

Working through actus reus, mens rea and the applicable doctrine separately, before reaching a conclusion, is the structure AQA’s law mark schemes reward.

Key terms to define precisely

Actus reus — the physical or “guilty act” element of a crime, which can consist of a positive act, an omission where a duty to act exists, or a defined state of affairs. Mens rea — the mental or “guilty mind” element of a crime, reflecting the defendant’s state of mind at the time of the actus reus. Causation — the requirement that the defendant’s conduct be both the factual cause (satisfying the “but for” test) and the legal cause of a prohibited consequence. Transferred malice — the legal doctrine allowing mens rea intended towards one victim to transfer to an unintended victim who suffers the same type of harm. Strict liability — criminal liability imposed without the need to prove mens rea for at least one element of the offence, an exception to the general fault-based principle of criminal law. Precision about the “but for” test as the specific factual causation standard — rather than a looser notion of contribution — is worth over-learning, since causation problem questions are a recurring feature of this content’s assessment.

Common mistakes

Assuming every criminal offence requires mens rea, without acknowledging strict liability as the specification’s own named exception. Confusing intention with subjective recklessness, when these represent different, specifically defined states of mind. Applying transferred malice to a situation involving a different type of harm than originally intended, where the doctrine does not apply. Omitting the coincidence requirement (that actus reus and mens rea must generally occur together) when analysing a scenario where the guilty act and guilty mind occur at different times.

Quick revision checklist

• Learn the actus reus categories: acts, omissions, state of affairs, voluntariness, causation.
• Distinguish intention, subjective recklessness and negligence as three separate fault standards.
• Know that strict liability offences require no proof of mens rea for at least one element.
• Practise applying the coincidence and transferred malice doctrines to short scenario questions.
