Actus reus & mens rea
A criminal offence is generally built from a physical element (actus reus) and a fault element (mens rea), which must usually coincide in time. The prosecution must prove every element of the actus reus and the required mens rea.
What "Actus reus & mens rea" covers
- Actus reus = the prohibited conduct, any required circumstances, and (in result crimes) the prohibited consequence.
- Omissions are not usually criminal, but liability arises where a duty to act exists: statute, contract, relationship, voluntary assumption, creation of a dangerous situation, or public office.
- Mens rea forms: intention (direct or oblique), recklessness, negligence, and knowledge/belief; the required state must match the specific offence.
- Oblique intent: a jury may find intention where the result was a virtual certainty of the defendant's act and the defendant appreciated that (Woollin).
- Recklessness is subjective: the defendant foresaw a risk and unreasonably went on to take it (Cunningham; confirmed in G).
- Actus reus and mens rea must coincide, but courts use the continuing act (Fagan) or single transaction (Thabo Meli) analysis to bridge gaps.
- Transferred malice: mens rea aimed at one victim/target transfers to the actual victim if the crime is the same type (Latimer); it does not transfer across different offence types (Pembliton).

How it's tested in SQE1
SQE1 uses single best answer questions: a short factual scenario, one precise question, and five options of which only one is the best answer on the law applied to the facts. For actus reus & mens rea, expect to be asked what the correct legal position is, what a party may or must do, or which outcome follows — with more than one option looking arguable. Reading the facts carefully and eliminating the near-misses is the skill that earns the mark.
Where candidates lose marks
- Confusing oblique intention (a route to proving intent) with recklessness — Woollin is a foresight-of-virtual-certainty test, not a lower fault standard.
- Assuming recklessness is objective — since R v G it is subjective for criminal damage and most offences.
- Forgetting that coincidence of actus reus and mens rea can be satisfied by continuing act or single-transaction reasoning.
