Core concepts
Concept 1
1.2 Actus Reus (Criminal Conduct): syllabus scope: Voluntary acts, automatism, coincidence, omissions, causation, intervening acts, principals, accessories, joint enterprise and organisational liability.
Exam cue: Locate the exact inspectors' Appendix A chapter before selecting the governing rule.
Concept 2
Conduct and omission: Identify the voluntary conduct or legally significant omission before asking whether the fault element coincided with it.
Exam cue: Separate offence elements or power thresholds from safeguards, defences, procedure and consequence.
Concept 3
Causation: Trace factual and legal causation and test whether a later act breaks the chain.
Exam cue: Apply the stated facts to neighbouring rules instead of answering from the seriousness of the outcome alone.
Concept 4
Participation and liability: Separate principal, accessory, joint-enterprise, corporate and vicarious routes rather than assuming presence is enough.
Risk pitfalls and guardrails

Guardrail: Use a 15-second safety pause before finalizing your action.
