Canons of Construction
- Old rules of statutory interpretation
- Literal Rule
- Golden Rule
- Mischief Rule
- Modern approaches
- Literal approach
- Purposive approach
The Literal Approach
- Giving words their ordinary, everyday meaning
- It’s the default approach, to be used first, unless results in inconsistency or absurdity
- Adopted in Inspector of Taxes v. Kiernan, in which SC identified basic rules
Inspector of Taxes v. Kiernan
SC identified basic rules of statutory interpretation:
- Ordinary meaning if addressed to public at large
- Specialist meaning if directed to a special class
- Ambiguity in penal or revenue statutes to be construed strictly to prevent new liabilities being imposed
The Purposive Approach
- Identifying legislation’s purpose and interpreting its words to achieve it
- Modern equivalent of golden and mischief rule
- Used if literal approach fails - results in inconsistency or absurdity
- Example: Nestor v. Murphy
Nestor v. Murphy
- A married couple attempted to use a literal interpretation of the Family Home Protection Act to avoid selling their house when they changed their mind after signing the contract
- Literal approach would have rendered a result contrary to the purpose of the legislation
7 Presumptions
- Presumption of constitutionality
- Presumption of compatibility with EU Law
- Presumption of compatibility with international law
- Presumption against retrospectivity
- Presumption against extra-territorial effect
- Presumption against unclear changes in the law
- Presumption that all words bear a meaning
Presumption of Constitutionality
- Legislation enacted after the 1937 Constitution is presumed to be compatible with it
- In case of competing interpretations, courts will apply the constitutional one
- A provision will be held unconstitutional only if no reasonable constitutional interpretation
Presumption of Compatibility with EU Law
Legislation presumed to be compatible with EU Law unless and until shown otherwise
Presumption of Compatibility with International Law
Legislation presumed to be compatible with international obligations unless and until shown otherwise
Presumption against Retrospectivity
- Unfair to penalise someone for an act that was legal at the time
- Art 15.5 of the Constitution prohibits enactment of retrospective obligations on citizens
- Retrospective criminal statutes prohibited by ECHR
Presumption against Extra-Territorial Effect
Legislation is presumed to apply only in Ireland unless it expressly says otherwise
Presumption against Unclear Changes in the Law
If a provision is ambiguous, the court will interpret it in a way that doesn’t change the law
Presumption that All Words Bear a Meaning
- Each word in legislation is presumed to mean something.
- If similar words are used, it’s presumed there is a difference between them
4 Maxims of Statutory Interpretation
- Noscitur a Sociis (“it is known from fellows or allies”)
- Generalia Specialibus non Derogant (“general provisions cannot derogate from specific provisions”
- Expressio Unius est Exclusio Alterius (“the expression of the one is the exclusion of the other”)
- Ejusdem Generis (“of the same type”)
