How to study for BSB Criminal Litigation

Prepare for a closed-book assessment by linking every power, gateway, burden, procedure and appellate route to its place in the criminal case.

Core concepts

Concept 1

PACE and Code C regulate cautioning, interviewing, access to legal advice and safeguards for children and vulnerable or intoxicated suspects.

Exam cue: Separate reasonable suspicion from the necessity or authority required for arrest.

Concept 2

Arrest requires lawful authority and communication of the fact and grounds; detention is controlled by custody officers, records, reviews and time limits.

Exam cue: Identify caution, legal-advice, appropriate-adult and recording requirements before using interview material.

Concept 3

Proceedings may begin through written charge and requisition or summons procedures, with a general six-month commencement limit for summary offences unless legislation provides otherwise.

Exam cue: Match prosecutor and commencement method, then check the applicable summary time limit.

Risk pitfalls and guardrails
