Statutory Interpretation: The Rules

Introduction

Once an Act of Parliament has been passed, it must be applied by the courts to real cases. This process is known as statutory interpretation — the method by which judges determine the meaning of words and phrases in legislation.

Statutory interpretation is necessary because:

• Language is inherently imprecise — words can have multiple meanings
• Drafting errors may occur — Parliament may use words that do not accurately convey the intended meaning
• New situations arise that the original drafters did not foresee
• Ambiguity may be deliberate — Parliament may use broad language to give courts flexibility
• Absurd or unjust results may follow from a strict reading of the words

Over centuries, judges have developed several rules (or approaches) to statutory interpretation. The three traditional rules are the literal rule, the golden rule, and the mischief rule. This lesson examines each rule in detail, with the key cases that illustrate their application.

The Literal Rule

The literal rule requires judges to give words their plain, ordinary, grammatical meaning, even if the result is absurd or unjust. Under this approach, the judge's role is simply to apply the law as Parliament has written it, not to rewrite it or fill in gaps.

Justification for the Literal Rule

• Respects parliamentary sovereignty — Parliament chose the words, and judges should not second-guess Parliament's intention
• Promotes certainty — if words are given their plain meaning, outcomes are predictable
• Separation of powers — law making is Parliament's job, not the judiciary's
• Democratic legitimacy — Parliament is elected; judges are not

Key Cases

Fisher v Bell [1961]

Facts: A shopkeeper displayed a flick knife in his shop window with a price tag. He was charged under the Restriction of Offensive Weapons Act 1959, which made it an offence to "offer for sale" certain offensive weapons.

Decision: The court applied the literal rule. In contract law, displaying goods in a shop window is an invitation to treat, not an offer for sale. The shopkeeper was acquitted because he had not "offered" the knife for sale in the legal sense of the word.

Significance: The literal meaning of "offer for sale" was applied, even though Parliament clearly intended to prevent people from selling such weapons. Parliament subsequently amended the Act to include "exposes or has in his possession for the purpose of sale."

Whiteley v Chappell [1868]

Facts: The defendant was charged under a statute that made it an offence to "impersonate any person entitled to vote." He had impersonated a dead person at an election.

Decision: The court applied the literal rule. A dead person is not "entitled to vote", so the defendant could not be guilty of impersonating a person entitled to vote. He was acquitted.

Significance: The literal meaning produced an absurd result — it was clearly wrong to impersonate anyone at an election — but the court felt bound by the plain words of the statute.

London and North Eastern Railway Co v Berriman [1946]

Facts: A railway worker, Mr Berriman, was killed while maintaining (oiling) the railway line. His widow claimed compensation under a statute that provided compensation when a worker was killed while "relaying or repairing" the line.

Decision: The court applied the literal rule. "Maintaining" is not the same as "relaying or repairing." Mrs Berriman's claim failed.

Significance: This case is often cited as an example of the literal rule producing a harsh and unjust result. The worker was doing essentially the same type of work on the railway, but the precise wording excluded his activity.

Advantages of the Literal Rule

Advantage	Explanation
Respects parliamentary sovereignty	Judges apply what Parliament wrote
Promotes legal certainty	Plain meaning is predictable
Limits judicial law making	Judges do not impose their own views
Encourages precise drafting	Parliament must draft carefully

Disadvantages of the Literal Rule

Disadvantage	Explanation
Can produce absurd results	Whiteley v Chappell, LNER v Berriman
Assumes perfection in drafting	Words cannot cover every situation
Ignores context and purpose	Focuses on individual words, not the Act's purpose
Can defeat Parliament's intention	Fisher v Bell — the result was the opposite of what Parliament intended

The Golden Rule

The golden rule is a modification of the literal rule. It allows judges to depart from the literal meaning of words when the literal meaning would produce an absurd, repugnant, or inconsistent result. The golden rule has two forms: the narrow approach and the wide approach.

The Narrow Approach

Under the narrow approach, the golden rule applies when a word or phrase is ambiguous — i.e., it has two or more possible meanings. The judge chooses the meaning that avoids the absurd result.

R v Allen [1872]

Facts: The defendant was charged with bigamy under section 57 of the Offences Against the Person Act 1861, which made it an offence to "marry" while one's spouse was still alive.

Problem: If "marry" is given its literal meaning (i.e., to enter into a valid marriage), then bigamy would be impossible — a second marriage while the first subsists is void, so the person has not legally "married."

Decision: The court applied the golden rule (narrow approach). "Marry" was held to mean "go through a ceremony of marriage" rather than "contract a valid marriage." This interpretation avoided the absurd result that bigamy could never be committed.

Adler v George [1964]

Facts: The defendant was charged under the Official Secrets Act 1920, which made it an offence to obstruct a member of the armed forces "in the vicinity of" a prohibited place. The defendant had actually committed the obstruction inside the prohibited place, not merely "in the vicinity of" it.

Decision: The court applied the golden rule. It would be absurd if the offence applied to conduct near a military base but not to conduct within it. "In the vicinity of" was interpreted to include "in or in the vicinity of."

The Wide Approach

Under the wide approach, the golden rule applies even when the words have only one clear meaning, but applying that meaning would produce a result that is repugnant to public policy or morally unacceptable.
