Law Making (AQA A-Level Law): Revision Notes
Statutory interpretation
This topic will be assessed in Paper 1 and examines how judges interpret the language used in Acts of Parliament. Understanding statutory interpretation is essential for grasping how legislation operates in practice and how courts resolve ambiguities or uncertainties in the law.
Why statutory interpretation is necessary
Although Parliament drafts legislation with care, there are several situations where judges must interpret the words used in statutes. The need for interpretation arises when:
Acts contain ambiguous words – Sometimes the language used is unclear or can have multiple meanings.
Case Example: Fisher v Bell (1961)
The statute made it a criminal offence to 'offer' flick knives for sale. The court had to determine whether displaying goods in a shop window constituted an 'offer' in the legal sense.
Outcome: It was held that such displays were invitations to treat rather than offers, meaning the defendant was not guilty.
Significance: This case demonstrates how ordinary language can have specific legal meanings that differ from everyday usage.
Words used are too broad – Statutes may use language that is capable of very wide interpretation. In R (Miranda) v Home Secretary (2016), the court considered stop powers under Schedule 7 of the Terrorism Act 2000. The meaning of the word 'terrorism' was in question, as it could encompass a very broad or narrow range of activities. When considering this, the judge observed that Parliament was unlikely to have intended to make such a broad distinction.
Technological progress means words need updating – Laws drafted decades ago may not have anticipated modern developments.
Case Example: Royal College of Nursing v DHSS (1981)
The Abortion Act 1967 provided that it would be an absolute defence for a 'medically registered practitioner' (a doctor) to carry out abortions, provided certain conditions were satisfied. The court had to decide whether this could include nurses using modern medical techniques.
Outcome: It was held that the term could include nurses, allowing the law to adapt to medical advances.
Technological advancement continues to challenge older legislation, requiring courts to interpret laws in ways that account for modern developments while respecting Parliament's original intentions.
Drafting errors occur – Even carefully prepared legislation can contain mistakes. In R v Burstow (1997), the court had to interpret the word 'inflict' in section 20 of the Offences Against the Person Act 1861. The court held that 'inflict' simply meant 'cause', correcting what appeared to be an inconsistency in the drafting.
Rules of statutory interpretation
Over time, judges have developed several approaches to interpreting statutory language. Importantly, no single rule is mandatory, and judges have discretion to choose which approach to apply. Bodies such as the Judicial Studies Board issue guidelines on the preferred approach, but judges retain flexibility in their decision-making.
Literal rule
The literal rule requires judges to give words their ordinary, natural and grammatical meaning, regardless of whether this produces an absurd or unjust result. This approach was particularly popular in the late nineteenth and early twentieth centuries.
Lord Reid explained the philosophy behind this rule when he stated:
We are seeking not what Parliament meant, but the true meaning of the words they used.
The literal rule is based on the principle that Parliament is sovereign and judges should not substitute their own judgment for the words Parliament has chosen. If the words are clear, they must be applied as written, even if the outcome seems unreasonable.
Case Example: Whiteley v Chappell (1868)
A statute made it an offence to impersonate any person entitled to vote. The defendant used the vote of a dead man.
Application of Literal Rule: Under the literal rule, he was found not guilty because a dead person was not a person entitled to vote.
Critique: While this outcome seems to defeat the purpose of the statute, the literal rule required the court to apply the words as written.
Similarly, in London and North Eastern Railway Co. v Berriman (1946), a railway worker was killed while oiling the track. A statute provided compensation payable on death for those 'relaying or repairing' the track. Under the literal rule, oiling did not count as either relaying or repairing, so no compensation was payable. This demonstrates how the literal rule can produce harsh results even when the spirit of the law suggests a different outcome.
In R v Judge of the City of London Court (1892), Lord Esher provided another statement supporting the literal approach, emphasizing that courts must apply the words used by Parliament.
Golden rule
The golden rule is an extension of the literal rule that allows judges to depart from the literal meaning where it would lead to an absurdity. Lord Wensleydale explained this approach in Grey v Pearson (1857):
The ordinary sense of the words is to be adhered to, unless it would lead to absurdity, when the ordinary sense may be modified to avoid the absurdity but no further.
Two Approaches to the Golden Rule
The narrow approach applies where a word is capable of more than one meaning. The court may choose between the possible meanings of the word. However, if there is only one clear meaning, the court must take that meaning even if the result is undesirable.
The wide approach applies where the words have only one clear meaning which would lead to an absurd result. The court will use the golden rule to modify the words to avoid the absurdity.
Case Example: Adler v George (1964) - Narrow Approach
Under the Official Secrets Act 1920, it was an offence to obstruct a member of the armed forces 'in the vicinity' of a prohibited place. The defendant was actually inside the prohibited place at the time of the obstruction.
Application: The court held that 'in the vicinity' could be interpreted to include being inside the place itself, thus avoiding an absurd result where someone inside had less protection than someone nearby.
Case Example: Re Sigsworth (1935) - Wide Approach
A son murdered his mother, who had not made a will. Under the statute governing intestacy, as her only child he was entitled to inherit her entire estate.
Problem: The literal rule would have led to a repugnant result where a murderer benefited from his crime.
Application: The golden rule was applied and he inherited nothing, with the court modifying the clear words of the statute to prevent this injustice.
Mischief rule
The mischief rule originates from Heydon's Case (1584) and takes a different approach by looking back to the gap in the previous law. Under this rule, judges interpret the Act so as to cover the gap or 'mischief' that Parliament intended to remedy.
Lord Diplock explained in Jones v Wrotham Park Settled Estates (1980) that the mischief rule should be used where:
it is possible to determine from the Act the precise "mischief" the Act was to remedy [and it] is possible to say with certainty what additional words would have been inserted.
This approach focuses on the problem that existed before the Act was passed and interprets the new legislation in a way that addresses that problem.
Case Example: Smith v Hughes (1960)
Defendants were prostitutes charged under the Street Offences Act 1959, which made it an offence to solicit 'in a public place'. The prostitutes were soliciting from private premises in windows or on balconies and could be seen by the public.
Application of Mischief Rule: The court interpreted 'in a public place' broadly enough to cover this situation, as the purpose of the Act was to prevent the public nuisance caused by soliciting, regardless of where the prostitute was physically located.
Royal College of Nursing v DHSS (1981), discussed earlier, also employed the mischief rule to ensure that the Abortion Act 1967 could be applied to modern medical procedures involving nurses, not just those personally performed by doctors.
Purposive approach
The purposive approach is currently the most popular method and is recommended by the Law Commission. It represents an extension of the mischief rule, but rather than just looking at what gap existed in the old law, judges consider what they believe Parliament intended to achieve with the new law.
This approach involves examining the overall purpose of the legislation and interpreting individual provisions in a way that furthers that purpose. The purposive approach is more flexible than the other rules and gives judges greater scope to consider the broader context and objectives of the legislation.
Case Example: R v Registrar-General, ex parte Smith (1990)
The applicant had a statutory right to a birth certificate at age 18, but it was suspected that he wanted this information to find and murder his mother. Despite the plain language of the Adoption Act 1976, the court applied the purposive approach, reasoning that:
Parliament could not have intended to promote serious crime.
Outcome: The court refused to grant the certificate, looking at the overall purpose of the legislation rather than just the literal words.
In R v Coleman (2013), the defendant burgled a narrow boat. The court held that the purpose of the Power of Criminal Courts (Sentencing) Act 2000 was to punish burglars on their third offence. Therefore, the Act should be interpreted to mean the same as section 9(4) of the Theft Act 1968, ensuring consistency in how different types of premises were treated for burglary offences.
R (Quintavalle) v Human Fertilisation and Embryology Authority (2003) shows how the purposive approach allows judges to respond to new technology, ensuring that legislation remains effective even when circumstances change in ways Parliament could not have foreseen.
Aids to statutory interpretation
In addition to the rules described above, judges have access to various aids that help them understand the meaning of statutory provisions. These aids are classified as either internal (found within the Act itself) or external (found outside the Act).
Internal/intrinsic aids
Internal aids are found within the statute itself and include:
The preamble, introductory text or long title – Many Acts begin with a statement explaining their purpose or scope. This can provide valuable clues about Parliament's intentions, particularly when applying the mischief rule or purposive approach. The long title often summarizes the main objectives of the legislation.
Explanatory notes – Modern Acts frequently include explanatory notes in the margin that clarify what each section is intended to do. These notes are particularly helpful in understanding complex or technical provisions. They are written to be accessible and can guide judges toward the intended meaning of the text.
Glossary of key terms – Some Acts contain a definitions section or glossary that specifies the precise meaning of particular words or phrases used throughout the legislation. This can prevent ambiguity and ensure consistency in interpretation.
Internal aids are generally considered reliable guides to Parliament's intentions because they form part of the legislative package that Parliament approved.
External/extrinsic aids
External aids are resources outside the Act that judges may consult, including:
Historical context – Understanding the circumstances in which an Act was passed can illuminate its purpose. For example, the Offences Against the Person Act 1861 uses the word 'grievous', which is no longer in common usage but was standard language when the law was drafted. Judges must consider this historical context to understand what Parliament meant at the time.
Dictionaries and textbooks – Judges may refer to legal dictionaries to determine the ordinary meaning of words. In R v Jewell (2014), Lady Justice Rafferty referred to Smith and Hogan's Criminal Law textbook, a leading authority on criminal law, to assist with interpretation.
Previous commercial practice – Where legislation regulates commercial activities, judges may consider how the relevant industry operated before the Act was passed. This can help identify the mischief the Act was designed to address.
Treaties and international law – When UK law implements international obligations, judges may refer to treaties and international legal principles to give continuity to the meaning of words. This ensures that UK law operates consistently with international standards.
Hansard – Hansard is the official record of parliamentary debates. For many years, judges were prohibited from consulting Hansard, as it was considered improper to go behind Parliament's enacted words to examine what individual MPs or ministers said during debates. However, following a significant debate between Lord Denning and Lord Diplock, the House of Lords changed this rule in Pepper v Hart (1993).
Case Example: Pepper v Hart (1993)
The case concerned tax on employment perks received by a teacher at a private school. During parliamentary debates on the Finance Act, a minister had specifically addressed this type of situation and stated that no tax would be payable.
Ruling: The House of Lords held that courts could consult Hansard where:
- The legislation was ambiguous or obscure, or
- The literal meaning would lead to an absurdity, and
- The relevant statement in Hansard was clear
Impact: This established a new external aid for statutory interpretation.
Tuppen v Microsoft (2000) provides another example of the courts using Hansard to assist with interpretation.
Interpretation Act 1978 – This Act provides general guidance on interpreting statutes. For example, it establishes that 'he' will always include 'she' and singular will always include plural unless the context indicates otherwise. This creates consistency across all legislation.
Impact of EU law on statutory interpretation
The purposive approach is the preferred method of interpretation in most EU countries and was the approach adopted by the European Court of Justice when interpreting EU law. During the UK's membership of the European Union, UK judges were required to use the purposive approach when dealing with matters involving EU law.
Having to apply the purposive approach to EU law for over 40 years made UK judges more familiar and comfortable with this method. Consequently, they became more likely to apply it to purely domestic UK law as well, even where they were not required to do so.
Now that the UK has left the EU, judges are no longer obliged to use the purposive approach for matters that previously fell within EU competence. However, the long-standing influence of EU law means judges are likely to continue using the purposive approach in many cases, as it has become an established part of their interpretive toolkit.
The continued influence of EU law can be seen in cases involving the interpretation of the Data Protection Act 2018 in light of the General Data Protection Regulations (GDPR), demonstrating that EU-derived principles continue to shape UK law even after Brexit.
Impact of the Human Rights Act 1998 on statutory interpretation
The Human Rights Act 1998 introduced an important new dimension to statutory interpretation. Section 3 of the Act states that, as far as it is possible to do so, legislation must be read and given effect in a way that is compatible with the rights in the European Convention on Human Rights.
This requirement applies to all UK legislation, whether passed before or after the Human Rights Act came into force. Where a statute is capable of two interpretations, one compatible with Convention rights and one incompatible, judges must choose the compatible interpretation.
Case Example: Mendoza v Ghaidan (2002)
The case involved interpreting the Rent Act 1977 in a way that was compatible with Convention rights.
Application: The court read the legislation broadly to ensure it did not discriminate against same-sex couples, demonstrating how section 3 of the Human Rights Act influences statutory interpretation.
If it is not possible to interpret legislation compatibly with Convention rights, judges cannot strike down the statute (as Parliament is sovereign), but they can make a declaration of incompatibility. This puts pressure on Parliament to amend the law while preserving parliamentary sovereignty.
In R v D (2019), the court considered the interaction between statutory interpretation and human rights, showing the continued importance of section 3 of the Human Rights Act in ensuring UK law respects fundamental rights.
Evaluation of statutory interpretation approaches
Each approach to statutory interpretation has both strengths and weaknesses. Understanding these helps explain why judges use different methods in different circumstances and why debate continues about the proper role of judges in interpreting legislation.
Advantages and disadvantages of the literal rule
The literal rule has several advantages:
Advantages:
- It respects parliamentary sovereignty by applying exactly the words that Parliament has chosen. Since Parliament is the supreme law-making body, judges should not substitute their own views for Parliament's decisions.
- It provides certainty, as the law will be interpreted exactly as it is written. This makes it easier for citizens and their lawyers to know what the law is and how judges will apply it, supporting the rule of law.
- It focuses Parliament's mind, forcing legislators to be clear in their language, which may improve the quality of drafting.
- It respects the separation of powers doctrine, as judges have minimal or no legislative function and simply apply the words Parliament has enacted.
- It takes advantage of consistency provided by external aids such as dictionaries and other Acts, and reinforces useful internal aids such as explanatory notes.
Disadvantages:
Where the literal rule leads to unjust results, such as in London and North Eastern Railway Co. v Berriman (1946), it can hardly be said to be enacting the will of Parliament, as Parliament presumably intended to protect railway workers but the literal interpretation defeated this purpose.
Key criticisms:
- It assumes every Act will be perfectly drafted, which is unrealistic given the complexity of legislation and the difficulty of anticipating every situation.
- Legal academic Michael Zander has called the literal rule 'irresponsible' because it can produce absurd outcomes that no reasonable person would think Parliament intended.
- It can actually undermine Parliament's intentions rather than further them, as demonstrated by Whiteley v Chappell (1868).
- It is based on erroneous assumptions regarding meaning in language, as words can have multiple meanings depending on context.
- Not all Acts have the benefit of explanatory notes, particularly older legislation, making it harder to determine the ordinary meaning of words.
Advantages and disadvantages of the golden rule
The golden rule provides a way of avoiding the worst problems created by the literal rule while attempting to respect parliamentary sovereignty. By allowing departures from the literal meaning only where it would lead to absurdity, the golden rule strikes a balance between respecting Parliament's words and achieving sensible outcomes.
Disadvantages:
The golden rule suffers from several limitations:
- Two approaches could lead to further inconsistency. It is not always clear whether the narrow or wide approach should be applied, creating uncertainty.
- There is no definition of an absurd result, so different judges may disagree about when the golden rule should be used. This subjectivity undermines the certainty that the literal rule aims to provide.
- Michael Zander has described the golden rule as a 'feeble parachute', suggesting it does not provide adequate protection against absurd results and is an inadequate solution to the problems of the literal rule.
Advantages and disadvantages of the mischief rule
Advantages:
- It responds positively to loopholes in the law by identifying the problem Parliament was trying to solve and ensuring the statute is interpreted to address that problem effectively.
- It is more likely to produce a 'just' result because judges try to interpret the law in the way Parliament meant it to work, focusing on substance over form.
- It reinforces the importance of explanatory notes, as these often clarify the mischief the Act was designed to address.
Disadvantages:
- Critics argue that judges using the mischief rule are going beyond their authority by filling in gaps, which contradicts parliamentary sovereignty. Judges are meant to interpret laws, not make them, and determining what 'mischief' Parliament intended to remedy requires making assumptions about Parliamentary intent.
- The mischief rule may lead to uncertainty, as it is impossible to know when judges will use the rule and what result it might lead to. This makes it difficult for lawyers to advise clients on the law with confidence.
- Not all Acts have the benefit of explanatory notes, particularly older legislation, making it harder to identify the mischief Parliament sought to address.
Advantages and disadvantages of the purposive approach
Advantages:
- It is most likely to lead to justice in individual cases because it considers the overall purpose of the legislation and interprets specific provisions accordingly.
- It allows judges to respond to new technology, as demonstrated in R (Quintavalle) v Human Fertilisation and Embryology Authority (2003), ensuring that laws remain relevant even when circumstances change.
- It gives judges discretion on when and how to avoid the absurdity of the literal rule, providing flexibility to achieve fair outcomes.
Critical Questions and Disadvantages:
A fundamental question arises: How can judges know what Parliament's intentions were? Parliament is made up of hundreds of MPs with potentially different views, and ministerial statements may not reflect the views of all MPs who voted for the Act.
Key concerns:
- The purposive approach allows unelected judges to 'make' law, as they are deciding what they think the law should be rather than using the words Parliament enacted. This raises concerns about democratic legitimacy and the separation of powers.
- It leads to the same uncertainty as the mischief rule, as parties cannot always predict how judges will interpret the purpose of legislation.
Key cases for statutory interpretation
Understanding key cases is essential for illustrating how different rules operate in practice. Here is a summary of the most important cases:
Fisher v Bell (1961) demonstrates ambiguous words and the literal rule. A statute made it a criminal offence to 'offer' flick knives for sale. The defendant displayed a flick knife in his shop window. It was held that goods on display in shops are not 'offers' in the technical legal sense but invitations to treat. Therefore, the defendant was not guilty. This case shows how ordinary language can have specific legal meanings.
R (Miranda) v Home Secretary (2016) involved words that were too broad and used the purposive approach. The case concerned stop powers under Schedule 7 of the Terrorism Act 2000. The meaning of the word 'terrorism' was in question. The judge applied the purposive approach, noting that it was unlikely Parliament would have intended to make such a broad distinction.
Royal College of Nursing v DHSS (1981) shows how technological progress affects interpretation and used the mischief rule. The Abortion Act 1967 provided that it would be an absolute defence for a medically registered practitioner (doctor) to carry out abortions. The court held this could include nurses using modern techniques, allowing the law to adapt to medical advances.
R v Burstow (1997) illustrates drafting errors and the golden rule. The case concerned the word 'inflict' in section 20 of the Offences Against the Person Act 1861. It was held that 'inflict' simply means 'cause', correcting an apparent inconsistency in drafting.
Whiteley v Chappell (1868) is a classic example of the literal rule producing an absurd result. The defendant used the vote of a dead man to impersonate any person entitled to vote. He was found not guilty as a dead person was not a person entitled to vote.
London and North Eastern Railway Co. v Berriman (1946) provides another example of the literal rule's absurdity. A railway worker was killed while oiling the track. Compensation was only payable for those 'relaying or repairing' the track. Oiling did not count, so no compensation was payable.
Adler v George (1964) demonstrates the narrow approach to the golden rule. It was an offence to obstruct armed forces 'in the vicinity' of a prohibited place. The defendant was actually inside the prohibited place. The court interpreted 'in the vicinity' to include being inside the place.
Re Sigsworth (1935) illustrates the wide approach to the golden rule. A son murdered his mother who had not made a will. The intestacy statute would have given him her entire estate. The golden rule was applied and he inherited nothing, as allowing him to benefit would be repugnant.
Smith v Hughes (1960) shows the mischief rule in action. Prostitutes solicited from private premises but could be seen by the public. The Street Offences Act 1959 made it an offence to solicit 'in a public place'. The court interpreted this broadly to cover the mischief of public nuisance.
R v Registrar-General, ex parte Smith (1990) demonstrates the purposive approach. The applicant had a statutory right to a birth certificate at 18, but it was suspected he wanted to find and murder his mother. Despite the plain language of the Act, the court applied the purposive approach, noting Parliament could not have intended to promote serious crime.
R v Coleman (2013) is another purposive approach case. The defendant burgled a narrow boat. The court held that the purpose of the sentencing Act was to punish burglars consistently, so it should be interpreted consistently with the Theft Act definition of burglary.
Pepper v Hart (1993) is the landmark case on using Hansard. The case concerned tax on employment perks for a teacher at a private school. A ministerial statement in Hansard specifically addressed this situation. The House of Lords held that Hansard could be consulted where legislation was ambiguous and the statement was clear.
Exam technique and assessment
Questions on statutory interpretation may take various forms. You may encounter multiple-choice questions testing knowledge of specific rules and aids. Essay questions typically require you to analyse the impact of different interpretive approaches, discussing their advantages and disadvantages with reference to relevant case law.
Essential Exam Tips:
When answering questions on statutory interpretation, always support your points with specific case examples. Do not simply list cases; explain how each case illustrates the rule being discussed and why the outcome was significant. An evaluation without cases will not score highly.
Consider the practical implications of each approach. How does it affect certainty in the law? How does it impact the relationship between Parliament and the courts? Does it promote justice in individual cases or broader legal certainty?
Be prepared to discuss the influence of EU law and the Human Rights Act, as these have significantly shaped modern judicial approaches to interpretation. Even after Brexit, the purposive approach remains influential, so understanding its origins and rationale is important.
Remember Michael Zander's criticisms when evaluating different approaches, but also consider counterarguments. While the literal rule may seem 'irresponsible' when it produces absurd results, does it not also respect democratic principles by deferring to Parliament's chosen words?
Finally, think about how different cases might have been decided under alternative rules. For example, Whiteley v Chappell (1868) produced an absurd result under the literal rule, but how would the golden rule, mischief rule or purposive approach have changed the outcome? This type of comparative analysis demonstrates deep understanding.
Key Points to Remember:
-
Statutory interpretation is necessary because Acts may contain ambiguous words, be too broad, need updating for technology, or contain drafting errors
-
The four main approaches are: literal rule (exact meaning regardless of absurdity), golden rule (depart from literal meaning to avoid absurdity), mischief rule (identify the gap in previous law), and purposive approach (consider Parliament's overall purpose)
-
No single rule is mandatory – judges have discretion to choose which approach to apply, though the purposive approach is currently preferred
-
Internal aids (preamble, explanatory notes, glossaries) and external aids (historical context, dictionaries, Hansard, Interpretation Act 1978) help judges interpret statutes
-
Pepper v Hart (1993) established that courts can consult Hansard where legislation is ambiguous and parliamentary statements are clear
-
Section 3 of the Human Rights Act 1998 requires judges to interpret legislation compatibly with Convention rights wherever possible
-
Each approach has strengths and weaknesses – the literal rule respects sovereignty but can produce absurdity; the purposive approach promotes justice but may allow judicial law-making
-
Case examples are essential – always illustrate your points with relevant cases like Fisher v Bell, Whiteley v Chappell, Adler v George, Smith v Hughes, and R v Registrar-General, ex parte Smith
