What this dot point is asking
Eduqas Component 1 requires you to know how judges interpret statutes: the literal, golden and mischief rules, the purposive approach, the rules of language, the intrinsic and extrinsic aids (including Pepper v Hart), and the influence of EU law and the Human Rights Act 1998. The skill is to apply a rule to a problem word (AO2) and to evaluate the approaches (AO3).
The answer
The literal rule
The golden rule
The golden rule starts from the literal meaning but modifies it to avoid an absurd or repugnant result. The narrow approach is used where a word has two meanings: in Adler v George "in the vicinity of" a prohibited place was read to include being inside it, to avoid an absurdity. The broad approach is used to avoid a repugnant outcome: in Re Sigsworth a son who murdered his mother was prevented from inheriting her estate under the rules of intestacy.
The mischief rule and the purposive approach
Rules of language and aids
Judges also use the rules of language: ejusdem generis (general words following a list take their meaning from the list, Powell v Kempton Park), expressio unius est exclusio alterius (mentioning one thing excludes others not mentioned) and noscitur a sociis (a word is known by the company it keeps). Intrinsic aids are found within the Act (the long title, preamble, headings, schedules and the Interpretation Act 1978). Extrinsic aids are outside it (dictionaries, earlier statutes, Law Commission reports and, since Pepper v Hart, Hansard where the words are ambiguous or absurd and there is a clear ministerial statement).
Examples in context
A strong answer applies each rule to the word, not in the abstract, and reaches a conclusion.

Q1. Explain the mischief rule of statutory interpretation. [10 marks]
- What the marker wants. Precise AO1: the rule from Heydon's Case, under which the court looks at the gap or mischief the Act was passed to remedy and interprets the words to suppress it, illustrated by Smith v Hughes.
Q2. Analyse and evaluate the literal rule and the purposive approach to statutory interpretation. [15 marks]
- Cue. An AO3 essay: explain each with cases; evaluate the literal rule (certainty and respect for sovereignty against absurd results, Whiteley v Chappell) against the purposive approach (justice and Parliament's intention against less certainty and more judicial power), and conclude.

Eduqas Component 1 2022 (scenario style)15 marksA statute makes it an offence to 'use' a vehicle without insurance. Dev's car is parked on his drive with no engine and no wheels. Advise how a court might interpret 'use' and whether Dev commits the offence. [a scenario question in the style of Component 1, AO2]Show worked answer →
A mainly AO2 scenario. Apply the rules of interpretation to the word 'use'.
Literal rule. On the plain meaning, 'use' suggests employing the vehicle for its purpose. A car with no engine or wheels cannot be driven, so on a literal reading (compare Whiteley v Chappell, where the dead man was not entitled to vote) Dev may not be 'using' it, and so commits no offence.
Golden and mischief rules. The golden rule could modify the meaning to avoid an absurd result. The mischief rule (Heydon's Case) asks what gap the Act addresses: the mischief is uninsured vehicles on the road causing uncompensated loss. A wreck incapable of being driven arguably falls outside that mischief, supporting no offence; but a car capable of being moved might be 'used'.
Purposive approach. A court might ask what Parliament intended (to ensure vehicles that could be on the road are insured) and conclude that an immobile wreck is outside the purpose.
Conclusion. The literal and purposive readings both suggest Dev does not 'use' the car, so no offence, but the answer must apply each rule to the facts.
A top answer applies each rule to the word in issue and reaches a reasoned conclusion.
Eduqas Component 1 2021 (evaluation)15 marksAnalyse and evaluate the rules of statutory interpretation. [an analysis/evaluation question in the style of Component 1, AO3]Show worked answer →
A mainly AO3 essay. Explain each rule, then evaluate the literal versus the purposive approach.
The rules. The literal rule (plain meaning, Whiteley v Chappell), the golden rule (modify to avoid absurdity, Adler v George; Re Sigsworth), the mischief rule (the gap the Act remedies, Heydon's Case; Smith v Hughes), and the purposive approach (what Parliament intended, encouraged by EU law and the Human Rights Act 1998).
Evaluation. The literal rule respects parliamentary sovereignty and the separation of powers but can produce absurd or unjust results (Whiteley v Chappell; Fisher v Bell). The purposive approach achieves Parliament's intention and avoids absurdity but gives judges more power and reduces certainty. The golden and mischief rules are middle positions; Pepper v Hart now allows limited use of Hansard.
A top answer explains the rules with cases and evaluates the tension between certainty (literal) and justice (purposive), then concludes.
