Worked solution
Candidates should introduce the concept of judicial precedent (stare decisis) and explain the classic conflict between certainty (predictability, consistency, and efficiency) and flexibility (the need for the law to adapt to social, technological, and moral changes). Under London Tramways v London County Council [1898], the House of Lords was strictly bound by its own prior decisions, emphasizing absolute certainty. This rigidity changed with the Practice Statement 1966, which allowed the House of Lords (now the Supreme Court) to depart from its own decisions 'when it appears right to do so.' Candidates should evaluate the impact of this statement, noting that the court remains mindful of the danger of disturbing retrospectively basis of contracts or property ownership. Key illustrative cases should be analyzed, such as Conway v Rimmer [1968] (first use), Herrington v British Railways Board [1972] (departing from Addie v Dumbreck [1929] on duty to child trespassers due to changing social attitudes), R v Shivpuri [1986] (departing from Anderton v Ryan [1985] on criminal attempts, showing that in criminal matters where liberty is at stake, the court corrects errors quickly), and R v G [2003] (departing from Caldwell on the test of recklessness). Moving to the Court of Appeal (CA), candidates must explain that it is bound by its own decisions as established in Young v Bristol Aeroplane Co Ltd [1944] to preserve certainty, subject to three narrow exceptions: (1) if there are two conflicting past decisions of the CA, the court must choose which to follow; (2) if a past decision of the CA is inconsistent with a subsequent Supreme Court decision, the CA must follow the Supreme Court; (3) if a decision was made per incuriam (through lack of care or failure to notice a relevant statute or precedent). Candidates should also note the wider exception in the CA Criminal Division under R v Taylor [1950] / R v Gould [1968] where the liberty of the individual is at stake. Critical evaluation should focus on whether these tools strike the right balance. On one hand, the Practice Statement has allowed crucial corrections of outdated law (e.g., Herrington, R v G), and the Young exceptions prevent obvious errors from being perpetuated in the CA. On the other hand, the Supreme Court is notoriously cautious in using the Practice Statement to protect certainty, which can leave bad laws in place for long periods. Furthermore, because the CA handles the vast majority of appeals, its rigid adherence to Young (despite Lord Denning's failed attempts in Gallie v Lee [1969] and Broome v Cassell [1971] to secure more flexibility) means that most litigants must undergo a costly appeal to the Supreme Court to achieve justice. In conclusion, candidates should synthesize these points, arguing whether the system achieves a successful compromise or remains too rigid for a modern legal system.
Marking scheme
Marks are awarded out of 25 based on levels of response: Level 5 (21-25 marks): Excellent analysis and evaluation. Clear, structured discussion of the conflict between certainty and flexibility. Extensive and accurate reference to the Practice Statement 1966, the exceptions in Young v Bristol Aeroplane, and relevant case examples (e.g., Herrington, Shivpuri, R v G, Miliangos). Demonstrates a sophisticated critical perspective on whether these tools provide sufficient flexibility or leave the law too rigid, especially concerning the Court of Appeal. Level 4 (16-20 marks): Good knowledge and understanding. Explains the Practice Statement and Young exceptions with several accurate case illustrations. Includes reasonable evaluation of the balance between certainty and flexibility, though the critical arguments may be less developed. Level 3 (11-15 marks): Mainly descriptive. Explains the main rules of precedent, the Practice Statement, and the Young exceptions, but with limited critical evaluation or limited case support. Some minor inaccuracies may be present. Level 2 (6-10 marks): Basic outline. Shows a rudimentary understanding of how the Supreme Court and Court of Appeal operate under precedent, but with sparse detail and little to no evaluation. Level 1 (1-5 marks): Minimal or irrelevant response. Shows little or no understanding of the legal concepts of precedent, the Practice Statement, or the Young exceptions.
