Exam cue: Locate the exact sergeants' Appendix A chapter before selecting the governing rule.
Concept 2
Mistake and duress: Test the defendant's asserted belief or threat against the exact conditions and exclusions of the defence.
Exam cue: Separate offence elements or power thresholds from safeguards, defences, procedure and consequence.
Concept 3
Use of force: Separate the honest-belief question from the reasonableness of the force and the power or purpose relied upon.
Exam cue: Apply the stated facts to neighbouring rules instead of answering from the seriousness of the outcome alone.
Concept 4
Police and age contexts: Check whether office, statutory authority or the person's age changes the available liability or defence analysis.
