1.3 Actus Reus (Criminal Conduct)
Voluntary acts, automatism, coincidence, omissions, causation, intervening acts, parties and corporate or vicarious liability.
Prepare for legal application, not isolated recall

Core concepts
Concept 1
Voluntary conduct: Begin with a voluntary act or a legally recognised omission before analysing the result.
Exam cue: Locate the exact 2026 Appendix A heading before choosing the governing rule or procedure.
Concept 2
Coincidence: Match the required actus reus and mens rea in the legally recognised way; do not inspect them in isolation.
Exam cue: Separate definitions and offence elements from powers, safeguards, defences and procedural consequences.
Concept 3
Causation: Trace factual and legal causation and then test whether an intervening act breaks the chain.
Exam cue: Apply the facts to adjacent rules instead of answering from the seriousness of the outcome alone.
