THEMODERN APPROACHTO STATUTORY
INTERPRETATIONANDTHE PRINCIPLE OFLEGALITY:AN
ISSUEOFCOHERENCE?
Dan Meagher*
ABSTRACT
The modern approachto interpretation requires that effect be given to the ordinary
meaning of a statutory text in its wider context and with reference to its purpose. This
article interrogates the interpretive approach used by the High Court in fundamental
rights cases to assess its compatibility with this modern approach. It asks, specifically,
whether the strict text-based approach used in these cases (which involves the
application of the principle oflegality) is sufficient to determine the meaning of
ambiguous statutory texts. The argument made is that the coherent application of the
modern approach requires that this interpretive approach be justified.
IINTRODUCTION
[The] construction [of a statute] will give effect to the ordinary meaning of its text in the
wider statutory context and with reference to the purpose of the provision. Further, the
principle oflegality favours a construction, ifone beavailable, which avoidsor
minimizes the statutes encroachment upon fundamental principles, rights and freedoms
at common law.

This passage neatly outlines both the modern approach

to statutory interpretation in
Australian law and the role of the common law principle oflegality within it.
Relevantly, the principle comes into play in fundamental rights cases; that is, when the
ordinary meaning of a statutory text in its wider context engages a fundamental
common law right, freedom or principle.

cases and to assess its compatibility with the modern approachto interpretation.

In order todo so, Part II will outline briefly what the modern approachto
statutory interpretation involves and from where it has emerged. It will then be
suggested that its core interpretive principleswhich first emerged in the 1980sare
still those which govern statutory interpretation in contemporary Australian law. And
that isso notwithstanding a series of cases coinciding with the tenure of Justice Hayne
on the High Court that sought to emphasize, if not reassert, the centrality of the
statutory text to the modern approachto interpretation.
However, one case decided during this periodSaeedis more difficult to reconcile
with the modern approach.

Itis the focus of Part III. There arestatements of
interpretive principle made inSaeed that do not sit comfortably with the modern
contextualapproach. Itwas a fundamental rights case. The principleof legality was
applied as part of an approach where the statutory text was the exclusive focus of the
interpretive inquiry not just central to that process. This raises an issue as to its
coherence andcompatibility withthe moderncontextualapproachto
interpretation. Yet the analysis undertaken, drawing on important recent scholarship,
suggests that the High Courts post-Saeed jurisprudence has, ultimately, endorsed the
core interpretive principles ofthemodern approach. But the actual interpretive
approach used inSaeedis not so easily reconciled.
Part IV examines three fundamental rights cases in order to identify and further
explain the issue of coherence asserted; specifically, that the use of a stricter text-based
approach is insufficient to resolve a fundamental rights case where the statutory text is
ambiguous. And its compatibility with the modern approach might be doubted when
the application of the principle of legality necessarily involves the exclusion of an
otherwise important and useful aspect of the wider statutory context (extrinsic
materials including legislative history) to determine the meaning of an ambiguous
statute. This is not to say that such an approach is necessarily incompatible with the
modern approach. But where a strict textual analysis is insufficientto ascertain a
statutes meaning in a fundamental rights case, how the principle of legality interacts
with the modern approach needstobe explained and justified.
Part V t hen provides four possible justifications for the interpretive approach used
by the High Court in fundamental rights cases. This approach, which excludes an
otherwise relevant and useful aspect of the wider statutory context, might be justified:
due to the inutility of the relevant extrinsic mat erials; if required by internal statutory
context and to preserve coherence in the statute book; if fundamental rights are
statutory implications; orif the principle of legality is a quasi-constitutional clear
statement rule for fundamental rights.Whilst each one is compatible with the core
principles ofthe moderncontextualapproach tointerpretation including the
centrality of statutory text to that process, not all are compelling inmy view. In
particular, the notion of fundamental rights as statutory implications is difficult to
square with the content and application of the principle of legality. And whilst the
High Courts contemporary jurisprudence may contain the analytical threads for
treating the principle as a quasi-constitutional clear statement rule for fundamental
rights, such a justification would be controversial and requires clear and reasoned
explanation.
