What it does
The Interpretation of Legislation Act 1984 (Vic) is the foundational statute that supplies default rules for the construction, operation, and interpretation of all Victorian Acts and subordinate instruments. Enacted to repeal and replace the Acts Interpretation Act 1958, it operates as a statutory dictionary and procedural manual that applies automatically unless a contrary intention appears in the legislation under consideration (s 4(1)).
At its core, the Act ensures legislation is read to its fullest valid extent without exceeding constitutional or empowering limits (ss 6, 22). It prescribes rules for citation (ss 9–10), commencement (ss 11, 24), and the exercise of powers between passage/making and commencement (ss 13, 26). Part II addresses Acts specifically, covering amendment or repeal in the same session (s 8), the effect of repeal on prior rights, obligations, and proceedings (s 14), and the non-revival of spent repeals (s 14(1)). Parallel provisions in Part III apply these concepts to subordinate instruments, including an implied power to amend or repeal them (s 27).
Part IV supplies rules of general application. Section 35 mandates a purposive approach: a construction that promotes the underlying purpose or object must be preferred. Courts and decision-makers may consider headings, punctuation, parliamentary materials, explanatory memoranda, and reports of royal commissions or law reform bodies (s 35(b)). Definitions in s 38 are legion and include "person" (including bodies corporate), "document" (extending to electronic forms), "Minister", and terms tailored to national schemes such as "Australian Consumer Law (Victoria)" (s 38F). Gender-inclusive language is required (s 37), and grammatical forms follow defined terms (s 39).
The Act further governs incorporation by reference (s 32), evidentiary status of authorised electronic versions (Part V, ss 60–64), and procedural validations (s 42C). Recent additions address publication of notices via approved internet sites rather than print newspapers (ss 38M–38P) and confirm that non-citizens are not disqualified from public office (s 64A), with retrospective validation of prior appointments (s 64B).
