Statutory interpretation
Courts interpret statutes to resolve ambiguity and apply legislation.
Statutory interpretation is the process by which courts interpret and apply legislation. In common law jurisdictions, the judiciary may apply rules of statutory interpretation both to legislation enacted by the legislature and to delegated legislation such as administrative agency regulations. Some amount of interpretation is often necessary when a case involves a statute, as words may have ambiguity that must be resolved by the judge.

Lore & Background
Statutes may be presumed to incorporate certain components, as Parliament is 'presumed' to have intended their inclusion. For example, criminal statutes are presumed to require mens rea, a statute is presumed to make no changes in the common law, and a statute is presumed not to apply retrospectively. Where legislation and case law conflict, legislation takes precedence insofar as there is any inconsistency, a principle known in the United Kingdom as parliamentary sovereignty, though courts retain sole competence to interpret statutes.
Reader's Guide
Statutory interpretation is central to the application of law in common law systems. The process allows courts to resolve ambiguities in legislation, which may arise from imperfect language, unforeseen situations, or compromises during enactment. Judges use tools such as traditional canons, legislative history, and purpose to ascertain the intention of the legislature. The principal aim is to carry out the 'intention of Parliament,' though the degree of creativity applied by judges can vary. In federal jurisdictions, interpretation may also involve determining whether federal or local authority prevails in the absence of a defined rule. The significance of statutory interpretation lies in its role in balancing legislative supremacy with judicial interpretation, as courts must expound the law without legislating. The process ensures that statutes are applied consistently and in accordance with established legal principles, including presumptions that protect individual rights and uphold international obligations.

Frequently Asked Questions
What is Statutory interpretation?
Statutory interpretation is the judicial process of figuring out what a legislative provision actually means so it can be applied to the facts of a specific case. It covers both primary legislation passed by a parliament and secondary instruments like agency regulations.
What are the three key rules of Statutory interpretation?
The literal rule reads words at their plain dictionary meaning, the golden rule allows a judge to depart from that meaning when it would produce an absurd result, and the mischief rule asks what problem the legislature was trying to fix when it enacted the law.
Who carries out Statutory interpretation in common law systems?
It is the judiciary—specifically the judge presiding over a case—who interprets and applies statutory language. Judges may also apply these interpretive tools to delegated legislation such as administrative agency regulations.
Why is Statutory interpretation necessary?
Legislative text often contains ambiguous or imprecise wording, so a court must resolve that ambiguity before the statute can be meaningfully applied to the parties before it. Without this step, identical words could lead to contradictory outcomes in different cases.
What presumptions guide a court's Statutory interpretation?
Courts generally presume that a statute requires mens rea for criminal offences, does not alter the common law, does not take away liberty or property rights, does not bind the Crown, does not empower crime, and does not operate retrospectively. They also presume legislation should be read consistently with international treaty obligations.
