Core concepts

Exam cue: Locate the exact sergeants' Appendix A chapter before selecting the governing rule.

Concept 2

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.

Participation and liability: Separate principal, accessory, joint-enterprise, corporate and vicarious routes rather than assuming presence is enough.
