Constitution Act 1975

The Act affects the entire Victorian polity. At the broadest level, it binds "the Parliament of Victoria" (s.5) and all persons within the State, as laws made under s.16 apply "in and for Victoria in all cases whatsoever". Electors are directly impacted by qualification rules (s.48, requiring Australian citizenship or certain British subjects enrolled before 1984, aged 18, not serving long sentences or of unsound mind), with disqualifications for treason or imprisonment (s.48(2)).

Members of Parliament (defined in s.5) are heavily regulated: they must take the oath in the Second Schedule (s.23), face vacation of seat for disqualification (s.46), resignation (ss.30, 37), or federal election (s.47), and are barred from certain offices of profit (Division 8, ss.49–61A, with penalties of $500 under s.59). The Act applies to both Houses, with specific rules for the 40-member Council (elected by 8 regions of 5 members each under ss.26–27) and 88-member Assembly (s.35).

The Governor, Lieutenant-Governor, Administrator, and Executive Council members (Part I and Part IV) are directly constituted and bound by oath (s.6D), administration rules (ss.6B–6C), and funding limits (s.7). Ministers must sit in Parliament (s.51) and can speak in either House with consent (s.52).

Judicial officers (Part III and IIIAA) – including Judges, Associate Judges, reserve Judges (ss.75–83AI, 81–81K), and those on the Judicial Commission Board or panels (ss.87AAN–87AAY) – are affected by appointment qualifications (s.75B), retirement ages (s.77(4)), pension entitlements (ss.82–83AI, with reductions for part-time service per s.83AAA), and removal only after a panel finding (s.87AAB). The Supreme Court itself, as a court of record (s.76), exercises jurisdiction subject to the Act (s.85).

Public officers and those in the public service are barred from political activities (s.95), with disciplinary consequences. Local government Councils (Part IIA) are recognized as a "distinct and essential tier" (s.74A), with Parliament able to legislate on their functions but not dismiss them except by specific Act (s.74B(2)).

Independent officers like the Auditor-General (ss.94A–94C), Ombudsman (s.94E), and Electoral Commissioner (s.94F) have tenure protections. The Director of Public Prosecutions (Part IIIA) has judicial-like pension rights (s.87AF).

The SEC and its successors (Part IX) are constrained in activities (s.106), affecting state energy policy. Prohibitions on hydraulic fracturing and coal seam gas (Part VIII) bind all persons and authorities, with parliamentary power limited (s.99).

Finally, the Act affects future Parliaments by rendering non-compliant Bills void (e.g. s.18(3)–(5), s.65E) and requiring special procedures, thus impacting legislators, government, and indirectly all citizens through entrenched policies on environment, energy, and governance.

Key duties flow from the Act's structure. The Governor must take oaths before assuming office (s.6(3)), administer the State per commissions (s.6), and act on advice (s.87E). Parliament's duties include summoning at least annually (s.41), maintaining quorums (ss.32, 40), electing presiding officers (ss.31, 39), and passing appropriation Bills only on Governor's message (s.63). Under s.16A, the Council must recognize the Government's mandate from elections.

Members have rights to privileges equivalent to the 1855 UK House of Commons (s.19), to administer oaths to witnesses (s.19A), and to be free from disqualification for certain services (s.60). Electors have rights to enrol if citizens aged 18 and not disqualified (s.48).

Judges' key rights include security of tenure until age 70 (or 72 in transitional cases under s.77(4)), salaries not to be reduced (s.82(6B)), and pensions at 60% of salary after 10 years or on incapacity (s.83(1)), with partner pensions at three-eighths (s.83(2)). Part-time Judges have duties under arrangements (s.75C) but rights to varied terms (s.75D). The Judicial Commission has duties to set standards (s.87AAL) and investigate via panels (s.87AAR).

The Auditor-General's independence is a key right (s.94B), with tenure protections (s.94C). Similar for Ombudsman and Electoral Commissioner (Part VA).

Public authorities have duties under Part VII to ensure water service delivery and ministerial accountability (s.97(1)–(2)), and under Part VIII/IX not to engage in prohibited activities (ss.99, 106).

Rights to access information are entrenched (s.94H). The Act grants Parliament power to legislate on local government (s.74B) but imposes duties to maintain its democratic nature (s.74A).

Enforcement of duties often occurs via disqualification (s.46), penalties (s.59), or voiding of non-compliant acts (s.18(3)–(5), s.107). The Supreme Court has jurisdiction to enforce via s.85, including habeas corpus (s.86).

Penalties are explicit in limited areas. Under Division 8, offences against offices of profit rules attract $500 fines (s.59), with seats becoming vacant (s.55). Wilful breaches of political activity bans (s.95) lead to fines up to $100, reduction in status, or dismissal.

For parliamentary matters, unqualified election is avoided by the Court of Disputed Returns (s.45), with sitting or voting by unqualified persons an offence (s.45(2)). Deadlocked Bills can lead to dissolution on Premier's advice (s.65E).

The Act relies heavily on voidness rather than penalties: Bills altering entrenched provisions without special majority or referendum are void (s.18(3)–(5)). Disputed Bills become Deadlocked if Dispute Resolution is not effected (s.65D), potentially triggering dissolution or joint sitting (ss.65E–65G), with Speaker's certificate conclusive (s.65G(8)–(9)).

Judicial removal requires a special majority address after an investigating panel finds facts amounting to misbehaviour or incapacity (s.87AAB(1)–(2)). No other removal is permitted.

Pension overpayments or breaches of commutation rules are addressed through actuarial adjustments (e.g. ss.7C–7D, 83AB–83AC), with reductions capped at 15% (s.7C(4)).

Enforcement is primarily political (e.g. House resolutions under s.61A to relieve defaults) or judicial via the Supreme Court's unlimited jurisdiction (s.85). The Auditor-General's reports (implied via cross-reference to Audit Act 1994) provide oversight. For water services (s.97) and SEC prohibitions (s.107), contravening contracts are void, providing self-enforcing mechanisms. No criminal penalties attach to most constitutional breaches; instead, the Act uses invalidity to deter non-compliance.

The Act is supreme in Victoria's constitutional hierarchy but expressly interacts with, and is subject to, Commonwealth law and other State Acts. Section 2 preserves existing laws and courts unless repealed or inconsistent. Section 3 applies English laws as at 25 July 1828 (subject to the Imperial Acts Application Act 1922), with Parliament able to declare their extension (s.3(2)).

It cross-references extensively: definitions incorporate terms from the Financial Management Act 1994 (Consolidated Fund, s.5), Electoral Act 2002 (Court of Disputed Returns, general election, regions/districts), Supreme Court Act 1986 (Associate Judges, reserve Judges, part-time arrangements), Audit Act 1994 (Parliamentary Committee), and Commonwealth Acts for superannuation (e.g. Superannuation Contributions Tax Acts, Family Law Act 1975 (Cth) for splitting orders in ss.5A, 83(8)–(22)).

Section 18 entrenches itself and listed provisions (including Parts I, III (except s.85), IIIAA, IV, VA, VII, VIII, IX, and water/SEC rules), requiring special procedures that interact with the Electoral Act 2002 for referendums. Failure renders Bills void, directly affecting validity under other Acts.

Part VII interacts with the Water Act 1989, Water Industry Act 1994, and Melbourne and Metropolitan Board of Works Act 1958 by prohibiting transfer of water service responsibility to non-public authorities (s.97), with s.18(2) applying. Part VIII references specific prohibitions in the Petroleum Act 1998 and Mineral Resources (Sustainable Development) Act 1990 as at commencement, constraining their amendment. Part IX does likewise for the SEC under corporations law (displaced by s.108).

The Supreme Court's jurisdiction (s.85) interacts with all other Acts by presumptively retaining review powers unless s.18(5) is followed. Judicial pensions reference the State Superannuation Act 1988 standards (s.83(22)).

It defers to Commonwealth law in areas like bankruptcy (insolvent under administration definition, s.5) and family law for superannuation splits. Section 47 interacts with federal parliamentary elections by vacating State seats. Overall, the Act acts as a framework statute, prevailing where inconsistent but incorporating external definitions and procedures.

The provided version incorporates amendments as at 20 August 2025. Key recent changes include the insertion of Part IX (ss.100–107) by the Constitution Amendment (SEC) Act 2024, which constrains parliamentary power to repeal, alter, or vary requirements for State control of the SEC (s.104), its renewable energy objects (s.105), and prohibitions on fossil fuel facilities (s.106). These changes were made to lock in energy transition policy, ensuring the SEC focuses on "renewable energy generation activities" and "energy system security" (s.105), with voiding of contrary contracts (s.107) and Corporations Act displacement (s.108). The purpose, per s.102, is to maintain these as permanent law.

Part VIII (ss.98–99), added by the Constitution Amendment (Fracking Ban) Act 2021, similarly entrenches bans on hydraulic fracturing (referencing s.16A of the Petroleum Act 1998 and s.8AD of the Mineral Resources (Sustainable Development) Act 1990) and coal seam gas exploration/mining (ss.8AC, 8AD, 15(1BAA) of the latter Act). Section 99 limits repeal to substitutions of equivalent effect, penalty increases, or editorial changes, to prevent backsliding on environmental protections.

Earlier reforms include the Constitution (Parliamentary Reform) Act 2003, which substituted fixed terms (s.38), introduced proportional representation for the Council (ss.26–27), added the government mandate principle (s.16A), expanded entrenchment (s.18), and created the Dispute Resolution Committee (Division 9A). These aimed to reform upper house elections and resolve deadlocks without frequent dissolutions.

The Constitution (Recognition of Aboriginal People) Act 2004 inserted s.1A, acknowledging lack of consultation in the preamble events and recognizing Aboriginal custodianship, contribution, and relationship to land, but expressly not creating legal rights or affecting interpretation (s.1A(3)).

Judicial amendments, such as those in the Courts Legislation Amendment (Reserve Judicial Officers) Act 2013 and Courts Legislation Amendment (Judicial Officers) Act 2013, added reserve Judges (ss.81–81K), part-time arrangements (ss.75C–75F), and effects on pensions (s.83AAA), to provide flexibility while preserving rights (s.81D). The Judicial Commission of Victoria Act 2016 inserted Part IIIAA for complaints handling, requiring panel findings before removal (s.87AAB(2)).

These changes were driven by needs for electoral fairness, environmental safeguards, energy policy stability, judicial efficiency, Indigenous recognition, and accountability mechanisms, all while expanding the Act's entrenched scope under s.18.

The Act itself does not detail specific court challenges, but its text anticipates and addresses potential controversies through self-contained mechanisms. Section 18(3)–(5) expressly voids any Bill dealing with entrenched matters (listed in s.18(1B), (2), (2AA)) if not passed with the required special majority, absolute majority, or referendum approval. This creates a justiciable invalidity ground, as a court could declare a purported Act void for non-compliance with s.18 procedures. Similarly, s.65G(8)–(9) makes the Speaker's certificate on joint sitting Bills "conclusive evidence for all purposes and cannot be questioned in any court", attempting to oust review but subject to s.85's jurisdiction (itself entrenched).

Controversies around s.85's manner and form requirements are inherent: any provision restricting Supreme Court review is void unless passed with absolute majority concurrence (s.18(2A)). The text notes that s.85(5)–(8) specify when an Act is taken to repeal, alter, or vary s.85, including by excluding review or creating summary offences that impliedly limit jurisdiction. This has led to textual debates on whether certain ouster clauses comply.

Section 1A(3) explicitly states the Aboriginal recognition does not "create in any person any legal right or give rise to any civil cause of action" or "affect in any way the interpretation of this Act or of any other law", preempting litigation over its legal effect. Part VIII (s.99) and Part IX (s.103) use similar language to constrain future Parliaments, with s.99(3) deeming reductions in penalties or geographic scope as alterations, potentially sparking disputes over whether a later Act "expressly" refers to the Part as required.

The voiding of non-compliant contracts under s.107 (SEC prohibitions) or s.97 (water services) could generate commercial litigation, but the Act grounds validity in its own terms. No provision in the text contemplates specific controversies beyond these built-in safeguards, such as the conclusive certificates in ss.65G(8), 63 (appropriation), or the non-justiciable mandate principle in s.16A(2) (expressly not limiting powers).

Most practitioners miss that s.1A(3) renders the Aboriginal recognition symbolically powerful but legally inert – it cannot ground causes of action or interpretive presumptions, a deliberate "gotcha" to avoid native title-style litigation while satisfying political demands. Another trap is s.18(1BA), which requires explicit reference to Part IIA for any repeal or variation; mere implication is insufficient, catching drafters who assume general amendment powers suffice.

The pension commutation regime (ss.7B–7J, 83AA–83AI) is a minefield: elections must be in writing within strict 10- or 60-day windows (e.g. s.7C(2), s.83AB(2)), with actuarial reductions capped at 15% (s.7C(4)), but revocation is possible only before notification lapses. Failure to lodge the surcharge notice copy voids the process (s.7D(1)). Part-time service multiplies pensions by a "relevant factor" under s.83AAA(2)–(3), often resulting in less than full entitlement despite appearing as a simple arrangement (s.75C).

Section 85(5)–(8) is frequently overlooked: even summary offence-creating provisions are not taken to vary s.85 (s.85(7)), but ouster clauses do unless absolute majority is obtained (s.85(6)). The "conclusive evidence" clauses (e.g. Speaker's certificates in s.65G(9)) purport to bar court questioning, yet s.85's entrenched jurisdiction may still allow collateral attack if s.18 procedures were not followed.

For the SEC (Part IX), s.106(c) prohibits investment in any "fossil fuel facility" (broadly defined in s.100 to include mines, pipelines, and combustion facilities), with s.107 voiding contrary contracts – a gotcha for commercial lawyers assuming ordinary corporations law applies (displaced by s.108). Similarly, Part VIII's constraints (s.99(3)) deem any narrowing of bans (e.g. reduced penalties or smaller areas) as prohibited alteration, even if not expressly stated.

Transitional provisions like s.81J (treating pre-2013 engagements as under the new Chief Justice power) or s.83(2A) (applying new partner definitions only to post-commencement deaths) can catch unwary estate planners. Finally, s.18(2)(fab) and (fac) entrench the fracking/SEC rules, but only if the Bill "expressly refers" – implying a drafting trap for future amendments.

Compliance begins with understanding s.18's entrenchment. To amend listed provisions (e.g. Part I, s.75(1), Part IIIAA, water/SEC rules), a Bill must receive a special majority on third reading (s.18(2)), or for referendum matters (s.18(1B)), pass both Houses and secure majority voter approval at a referendum held at least 59 days later (s.18(1C)). The Bill must expressly state intent to alter the relevant Part (s.18(1BA)). Non-compliance voids the Bill (s.18(3)–(5)). For ordinary legislation, ensure appropriation Bills originate in the Assembly with Governor's message (ss.62–63) and follow dispute procedures if deadlocked (Division 9A).

For parliamentary practice, comply with summoning (s.20), oaths (s.23), quorums (ss.32, 40), and standing orders (s.43). Ministers must be members within three months (s.51) and avoid prohibited contracts (ss.54–57). Public officers must not engage in political activities (s.95) or comment on administration.

Judicial compliance requires appointments only of qualified persons (s.75B: 5 years' practice or prior judicial experience), with part-time arrangements in writing specifying at least 0.4 FTE (s.75C(2)), varied only by agreement (s.75D). Pensions must follow actuarial calculations (ss.83AB–83AI), with elections lodged timely and reductions not exceeding 15% (s.83AB(4)). Reserve Judges engage only via Chief Justice notice for up to 6 months (s.81B(4)), avoiding legal practice without approval (s.81E).

The Judicial Commission must appoint panels with required composition (s.87AAS: one from pool, one former judicial officer, one current/former), ensuring no conflicts (s.87AAS(2)–(5)). Investigating panels follow Judicial Commission of Victoria Act 2016 procedures, with remuneration per prescribed allowances (s.87AAT(4)).

For water services, public authorities must retain responsibility and ministerial accountability (s.97(1)–(2)); arrangements with contractors are permitted only if accountability remains (s.97(3)). For SEC, maintain State controlling interest per s.104(2) (board control or appointment power), pursue objects in s.105 (renewables, security), and avoid fossil fuel ownership/operation/investment (s.106(c)). Any contrary contract is void (s.107).

Financial compliance involves appropriations only per message (s.63), with Auditor-General independence preserved (s.94B). Oaths must be taken in prescribed forms (Second Schedule, Schedule 3, s.88AA). To avoid voidness under s.18 or s.65E, always verify procedural compliance before presentation for assent. For dual commission holders (notes to ss.75B, 82), salaries are limited to the primary office to prevent double-dipping.

In advice, warn clients that "conclusive" certificates (e.g. s.65G(9)) may not fully oust s.85 jurisdiction if entrenchment is breached, and that transitional provisions (e.g. s.83(2A), s.81J) can alter expected pension or engagement outcomes. Regular audits against the entrenched list in s.18 are essential for legislative drafters.
