Statutory interpretation is the process by which judges assign meaning to the words in an Act of Parliament. Since language can be ambiguous, students must master the four primary rules: the literal rule, the golden rule, the mischief rule, and the purposive approach. This topic is central to the A-Level curriculum as it demonstrates the tension between following the exact letter of the law and achieving a just or sensible outcome.

Give groups a single sentence from a fictional statute (e.g., 'No vehicles in the park'). They must produce four different interpretations based on the literal, golden, mischief, and purposive rules, explaining how the outcome changes for a bicycle versus an ambulance.
How does the literal rule differ from the golden rule?
Display stations featuring excerpts from Hansard, a Law Commission report, and an international treaty. Students rotate to identify how each document could help a judge interpret a specific problematic clause in a modern Bill.
Students read a summary of Pepper v Hart. They discuss in pairs whether judges should be allowed to look at what was said in Parliament, considering the impact on parliamentary privilege and legal costs, before sharing with the class.
What is the purposive approach to statutory interpretation?
The literal rule is always the 'best' rule because it respects Parliament.
The literal rule can lead to 'absurd' results that Parliament clearly didn't intend (e.g., LNER v Berriman). Comparing the literal and golden rules helps students see that 'respecting Parliament' sometimes means looking for their actual intent.
Judges can use any book or website as an extrinsic aid.
There are strict rules about what can be used; for example, Hansard can only be used if the legislation is ambiguous and the statement was made by a minister. A 'permissible aids' checklist helps students learn these specific legal boundaries.
