7. Judicial Power and Precedent
Judicial independence, judgments, ratio and obiter, hierarchy, binding and persuasive authority and post-EU-withdrawal sources.
How to study the CPQ Foundation stage
Prepare each separately assessed component on its own terms, then connect law, regulation, client service and research across the full stage.
Core concepts
Concept 1
Judicial independence and impartiality underpin lawful adjudication.
Exam cue: Identify the material facts, issue and legal reason necessary for the result.
Concept 2
The ratio decidendi may bind lower courts while obiter reasoning can persuade.
Exam cue: Place both courts in the hierarchy before deciding whether authority binds.
Concept 3
Hierarchy, court-specific rules and the status of domestic and external authorities determine precedential weight.
Exam cue: Distinguish binding force from persuasive value.
