The common law has largely been enveloped in a web of statutory regulations. The ability to interpret these statutes in an important skill for the modern legal practitioner. This article will discuss the rules around statutory interpretation and how to apply them in practice.
The Literal Rule states that it is presumed that the words selected by the legislature and used in that context are the true intent of the legislature when the law was passed. If the words are clear and explicit, the court should give them effect regardless of the consequences. The context in which the words are used is important – not just in the way it is used, but in the time in which it was written. The literal meaning of a term used at a particular time and place is the context in which it is interpreted.
A further presumption is the plain meaning rule is that the drafters must use precise and unambiguous words in drafting. The assumption is that the words ate used in a statute are accurate and unambiguous. There is also a presumption that the court must give effect to the words in a statute be given legal effect regardless of the consequences – both those consequences intended by the legislature, and those not explicitly intended by the legislature. Over time, however, other elements indicating legislative intent can use other information, such as committee reports, to help understand legislative intent.
Doctrine of Absurdity
When the plain rule results in an obviously absurd answer when he literal rule of interpretation is applied, then there may be an interpretation that an interpretation that does more justice or appears more desirable may be chosen. The most important factor is that both the interpretations are possible given the language. this approach, however, cannot be used to modify the express legislative language for the sake of justice and common sense. There is a limit to the judge’s power to identify an absurdity, and it is used only in cases where the application of the plain meaning rule will be absurd in context with the legislation read as a whole. When two interpretations are equally possible, the interpretation that appeals more to common sense and equity may be chosen.
Legal Interventions and Evasions
Where the language is clear and unambiguous and represents the intention of the legislature, the court should not lean on equity principles to derive an outcome inconsistent with the statute. Additionally, where the text is clear and unambiguous, it still does not prevent lawful evasion of the law by citizens. This is most often found in tax planning – which is a lawful evasion of paying taxes based on the literal reading of the tax statute, and is largely determined by the elements of honesty and dishonesty in structuring the action or transaction.
There is a significant question as to whether the court should follow the old meaning of a text contemplated by the legislature at the time the statute was passed, or whether the court should adopt the new meaning. Traditionally, the rule has been that legislation should be interpreted in a way it would have been interpreted at the time it was made. Within the last 25 years or so (since 1990), the rule has changed, and unless otherwise intended by the legislature, the legislative text is read holistically and can be construed to adopt the meanings of modern times. When interpreting legislation, the legislative text is to be construed in a manner to adopt the relevant modern time meanings and no further.
Heydon’s Case  (EWHC Exch J36)
Heydon’s case established the mischief rule. This rule can be summarized as follows. There are four things to be considered and discerned when interpreting all statutes:
- What was the common law before making the Act?
- What was the mischief and defect for which the common law failed to solve?
- What remedy did Parliament use to cure the mischief or defect?
- The interpretation is to be constructed to suppress the mischief, advance the remedy, and to suppress inventions and evasions to continue the mischief.
An English example, where the statute says prostitutes could not loiter in the street, but where the prostitute was offering services from the porch was found guilty as the court extended the meaning of street to the porch. (Smith v. Hughes  2 All ER 859). In the 16th Century, the primary law was common law, and when laws were drafted mostly by judges to address mischief that the common law failed to address. Now, courts look not only to the common law, but also to the laws and statutes in force at the time.
What is “Mischief?”
Mischief here is a term of legal art. It may be also read as “general legislative purpose” or “legislative intent”.
There are two main types of mischief:
- Social Mischief – which is a factual position that existed, exists or is expected to occur.
- Statutory Mischief – a defect or deficiency in a statute due to drafting error, inadequate legal provision or unconstitutional legislation.
When faced with interpreting statutory mischief, the court needs to keep these limits in mind and interpret legislation as narrowly as possible.
Determination of Mischief
the titles, preambles, legislative history, debates, committee work, relevant agreements and cross-references are all considered valid sources for determining the target mischief of the legislature. The default rule is that the court will reject the mischief argument unless there is exceptional reason to support it.
The no good reason approach is that there would be no good reason as to why the legislature would have defined a word or words in a certain way in order to limit the scope of the statute. See Knowles v. Liverpool City Council  where flagstone was accepted as “equipment” under the Act.
There is a rule of manifest injustice, where there are two possible constructions of meaning, and where one construction will cause a manifest injustice, the court may adopt the construction that does not create an injustice.
Additionally, there is a rule of split mischief. In this case, there are different mischief within the same legislation, as well as an overarching mischief targeted by the legislation. This is often found in tax statutes – where multiple taxes and definitions of income may be interpreted differently within the same statute.
In the case of de facto or de jure mischief, the original mischief intended to be remedied is modified through changes in the act as it moves through the legislative process. In such cases, the interpreter must clearly understand what the mischief that was actually legislated to solve.
In order use a remedy to determine the mischief, the remedy itself must be distilled to figure our what mischief the remedy was intended to cure. Where a difficulty arises in the operation of an Act impacting the effectiveness of the remedy prescribed, the court should interpret the statute to suppress the precise mischief and advance the remedy. Additionally, the court needs to make sure that its interpretation doesn’t unintentionally create a new mischief occur.
The purposive rule is a modern interpretation of the Mischief Rule, and states that courts interpret legislation in light of the purpose for which it was passed. In this context it is important to note that legislation is designed to provide a remedy to curb a mischief, and not curb the mischief directly.
this rule was adopted in English and Welsh courts in 1969. It essentially states that:
- Courts will construe language which promotes the general legislative purpose underlying the provision in question, and
- Courts will construe language consistent with international obligations.
Courts were then able to resort to the purposive approach to interpret legislation when the traditional methods were in doubt, or where they result in absurdity. Additionally, the courts could now use extraneous material to elucidate and highlight the background of the legislation.
Nature of Purposive Construction
The concept of purposive and literal construction applies where the literal meaning of the legislative text and the legislative purpose agree with each other. In this case, the literal reading will hold.
Non-purposive literal construction is applied when:
- The court cannot determine the legislative purpose
- The literal meaning absent the purpose is too strong to be overruled, or
- the court determines a predictable construction is required.
There is a concept of purposive and strained construction – which is the usual application – where the precise literal meaning does not confirm to legislative purpose and so the principle of strained construction is applied.
Duty of the Court
The court has a duty to follow the purpose of the legislature, even it if disagrees with it. Unless the law is unconstitutional, the courts and the judge has the obligation to follow that law. In the event there is a doubt regarding the legislature’s purpose, the courts can use these established principles of the court to determine it.
Interplay Between the Literal and Purposive Approaches
The rules of interpretation indicate that the first option to be applied in interpreting a statute is the literal rule. Only where the natural construction of the legislation doesn’t answer the question should the court look outside the strict letter of the legislation for meaning. Over time, the purposive approach evolved into the use of purposive-literal or purposive-stained construction, and legislation is given construction by reference to its context.
Presumptions and Maxims of Interpretation of Statutes
There are a list of “Canons of Construction” which provide guidance to courts when interpreting statutes or their provisions. It is important to note that these presumptions and maxims are only applied when the intention of the legislature is unclear from the legislative text. Oh, and welcome to Latin…
Maxims of Interpretation
Ejusdem Generis – when general words follow an enumeration of persons or things, such general words are not to be construed at their widest extent, but are to be held as applying only to persons or things of the same general kind or class specifically mentioned.
Statutes in pari materia – A statute is in pari materia when, though enacted at different times, they relate to the same subject or object and form part of a single code on a particular matter. In the case of ambiguity regarding statutes dealing with the same subject matter, their definitions are to be interpreted in light of and with reference to each other in as much as they have a common purpose for comparable times or events.
Expressio unius est exclusio alterius – The expression of one subject, object or idea excludes another subject, object or idea. Where the legislature expressly supplied the exceptions with respect to exclusions, the rule does not apply.
Natural versus Technical Meaning – The words used in legislation are to be given their natural meaning in ordinary English conversation unless they are used in a technical way. The term ‘technical’ does not mean only the terms of science, art, trade or other specific use. It also includes any term designed to refer to specific ideas or bear specific connotations in a particular legal context.
No Change of Meaning Without Change of Language – Drafters do not change the language from one context to another unless a change of meaning is desired.
Casus Omissus – This is the omitted case and it occurs when any legislative instrument looks to foresee and provide for a contingency, and through an inadvertent error fails to do so. Under this rule, the courts can supply the omissions when interpreting the statute in question.
Rebuttable Presumptions of Interpretation
Presumption against unfairness – There is a general presumption that the legislature does not intend to be unfair, unreasonable or arbitrary.
Presumption against double jeopardy – There is a general presumption that a person cannot be tried twice for the same offense.
Presumption against expropriation – There is a general presumption that the acquisition of property without compensation is unlikely, but if subject to compensation is possible.
Presumption against protection of human rights – There is a requirement in EU countries to interpret legislation, in as far as practicable, with the European Convention on Human Rights. In the US, there would be a presumption of constitutionality in interpretation.
Presumption against absurdity – When the meanings of the text are clear, the courts may not refuse to give a statute effect because the result appears unjust or absurd. However, if two constructions are possible, then the courts must choose the one that is less absurd or unjust.
Presumption against penalty – There is a presumption that a criminal or civil penalty requires express and clear words of the legislature, and absent such words, no penalty was intended.
Presumption against creating or removing judicial jurisdiction – There is a presumption that conferring or taking away jurisdiction from the court requires express words of a statute or very clear implication.
Presumption against delegation of powers – There is a presumption that the legislature will not delegate the power of legislation to another body unless it does so by express provision.
Presumption of notice – There is a presumption that the decision of authority does not have legal effect unless the person has notice of it, and this can be rebutted only by clear legislative words.
Presumption against retrospectivity – There is a presumption that unless contrary intention appears, the laws impacting peoples rights and obligations are not to be construed retrospectively.
