The rules of statutory interpretation are as
follows:
• Intrinsic assistance
This is help
which is actually derived from the statute which is the object of interpretation.
The judge uses the full statute to understand the meaning of a particular part
of it. Assistance may be found from various parts of the statute, such as: the
title, long or short; any preamble, which is a statement preceding the actual
provisions of the Act; and schedules, which appear as detailed additions at the
end of the Act. Section headings or marginal notes may also be considered, where
they exist.
• Extrinsic
assistance
Sources outside
of the Act itself may, on occasion, be resorted to in determining the meaning
of legislation. For example, judges have always been entitled to refer to dictionaries
in order to find the meaning of non-legal words. The Interpretation Act 1978 is
also available for consultation with regard to the meaning of particular words
generally used in statutes. Judges are also allowed to
use extrinsic sources to determine the mischief at which particular legislation
is aimed. For example, they are able to examine earlier statutes and they have
been entitled for some time to look at Law Commission reports, Royal Commission
reports and the reports of other official commissions. Until fairly recently, Hansard, the verbatim
report of parliamentary debate, literally remained a closed book to the courts.
In Pepper v Hart however, the House of Lords decided to overturn the previous
rule. In a majority decision, it was held that, where the precise meaning of
legislation was uncertain or ambiguous, or where the literal meaning of an Act
would lead to a manifest absurdity, the courts could refer to Hansard’s Reports
of Parliamentary Debates and Proceedings as an aid to construing the meaning of
the legislation. The operation of the
principle in Pepper v Hart was extended in Three Rivers DC
v Bank of England to cover situations where the legislation under question was
not in itself ambiguous but might be ineffective in its intention to give
effect to some particular EC directive. Applying the wider powers of interpretation
open to it in such circumstances, the court held that it was permissible to
refer to Hansard in order to determine the actual purpose of the statute. The Pepper v Hart principle only applies to
statements made by ministers at the time of the passage of legislation, and the
courts have declined to extend it to cover situations where ministers
subsequently make some statement as to what they consider the effect of a
particular Act to be v BMI
Books of
authority
In the very
unusual situation of a court being unable to locate a precise or analogous precedent,
it may refer to legal textbooks for guidance. Such books are subdivided, depending
on when they were written. In strict terms, only certain works are actually treated
as authoritative sources of law. Legal works produced after Blackstone’s Commentaries
of 1765 are considered to be of recent origin and, although they cannot be treated
as authoritative sources, the courts may consider what the most eminent works by
accepted experts in particular fields have said in order to help determine what
the law is or should be.
