Recovery of Imposts Act 1963

The Act primarily affects two classes of persons: taxpayers (including businesses, individuals and entities that have paid State taxes, fees or charges) and the State of New South Wales itself together with its agencies, officers and instrumentalities.

Taxpayers are affected whenever they seek to recover any impost on restitutionary grounds. Because "tax" is defined in s 1A to include fees and charges, the Act catches stamp duty, payroll tax, land tax, gaming machine taxes, parking levies, mining royalties framed as taxes, and a host of regulatory fees that might otherwise be challenged as taxes. The passing-on rule in s 4 is of particular significance to intermediaries—retailers, wholesalers, importers, insurers and professional service providers—who commonly pass tax costs through supply chains. These entities must now prove non-passage of the economic burden, a forensic exercise that frequently requires detailed accounting evidence.

Government agencies are the direct beneficiaries. The Act shields the Office of State Revenue, Transport for NSW, Revenue NSW and any other body that receives "tax or purported tax". Because s 2(1) protects not only the Crown but "any corporation, officer or person or out of any fund to whom or which it was paid", the protection extends to third-party collectors and statutory funds. The retrospective provisions in s 7(5) mean that even long-settled collections from the 1960s onward receive the benefit of the expanded defences inserted in 1993 and 1995.

The Act also indirectly affects the legal profession. Practitioners advising on tax disputes must now advise clients on the interplay between constitutional invalidity, administrative-law error, restitutionary causes of action and the statutory bars. Accountants and compliance professionals are affected when they identify overpaid tax in historical reviews; the 12-month window and the passing-on defence often render recovery impossible even where an overpayment is undisputed.

Finally, because s 6 characterises the Act as substantive, it affects choice-of-law analysis in cross-border litigation and may influence federal jurisdiction where State law is picked up under s 79 of the Judiciary Act 1903 (Cth).

The Act creates few positive duties but substantially curtails rights. The principal right curtailed is the common-law right to restitution for money had and received, money paid under mistake, or money exacted under colour of invalid legislation. That right is now subject to the short limitation period (s 2), the non-legislative change bar (s 3), the passing-on defence (s 4) and ultimate extinguishment (s 5).

Taxpayers retain a narrow right to recover in two situations. First, where a specific statutory refund scheme exists that provides a different limitation period and expressly authorises recovery, s 2(2) disapplies the general bar. Second, s 3(4) preserves the right to recover overpayments that would have arisen even if the legislation had been valid, provided the legislation itself contains a refund mechanism.

The claimant bears the legal and evidentiary burden under s 4(1) of satisfying the court that the tax has not been and will not be passed on. This is a continuing representation: the claimant must prove both historical non-passage and future non-recovery. The definition of "claimant" in s 4(2) extends this burden to corporate successors, meaning due-diligence in mergers and acquisitions must now include analysis of historic tax refund claims.

Public authorities have no new duties imposed by the Act, but the characterisation in s 6 as substantive law strengthens their ability to plead the Act in bar in both State and federal courts. The retrospective operation clauses in s 7(4) and (5) have the effect of deeming the expanded defences always to have been available, thereby validating past dismissals of claims that might otherwise have been reopened.

The Act contains no offence provisions or civil penalties. Enforcement occurs entirely through civil litigation. A taxpayer who commences proceedings outside the 12-month window or in the face of a s 3 bar will face an application for summary dismissal or a defence pleading the statutory bar and extinguishment under s 5. Because s 5 extinguishes the right rather than merely barring the remedy, a court must dismiss the proceeding on the basis that no cause of action any longer exists.

Costs consequences can be severe. A claimant who fails the s 4 passing-on test may be ordered to pay costs on an indemnity basis where the claim is characterised as hopeless once the statutory defences are considered. Conversely, where a taxpayer successfully navigates the narrow gateways, the State may face liability for the refunded principal plus interest under the Supreme Court Act 1970 (NSW) or the specific interest provisions of the taxing statute.

The Act interacts with the Civil Procedure Act 2005 (NSW) and the Limitation Act 1969 (NSW). Because the Recovery of Imposts Act is declared substantive, its time limits are not "limitation periods" within the meaning of the Limitation Act but operate as substantive extinguishments.

The Act is expressed to operate despite any other Act (s 7(2)). It therefore prevails over general limitation statutes, the Supreme Court Act 1970, and the specific refund provisions of most State taxing Acts except where those Acts fall within the carve-out in s 2(2).

Constitutionally, the characterisation in s 6 as substantive law is designed to engage s 118 of the Commonwealth Constitution (full faith and credit) and to ensure the Act travels with the cause of action in federal jurisdiction. The High Court in Roxborough v Rothmans of Pall Mall Australia Ltd (2001) 208 CLR 516 and subsequent cases has considered analogous "passing-on" and "windfall" defences; the New South Wales provisions were drafted with those constitutional and restitutionary developments in mind.

The Act intersects with the Franchise Tax jurisprudence and the Ha v New South Wales (1997) 189 CLR 465 decision on tobacco licensing fees. Section 3 was inserted precisely to prevent recovery where a later High Court decision recharacterises a fee as an excise. It also interacts with Commonwealth laws picked up in federal jurisdiction. Because the Act is substantive, a federal court exercising jurisdiction in a State matter must apply ss 2–6 as part of the law governing the claim.

In insolvency, the extinguishment under s 5 may affect proof of debt in liquidations or bankruptcies where a company has a contingent refund claim that is later barred. The retrospective operation in s 7(5) can alter the solvency position of companies retrospectively—an unusual and powerful feature.

The most significant changes occurred in 1993 and 1995. The Limitation of Actions (Recovery of Imposts) Amendment Act 1993 (NSW) inserted the definitions in s 1A, expanded s 2 to cover invalidity of taxation legislation expressly (new s 2(3)), inserted the entire non-legislative change bar in s 3, the passing-on rule in s 4, extinguishment in s 5, characterisation in s 6, and the application rules in s 7. These changes were a direct legislative reaction to the High Court's decision in David Securities Pty Ltd v Commonwealth Bank of Australia (1992) 175 CLR 353, which removed the bar on recovery for mistake of law, and to emerging constitutional challenges.

The State Revenue Legislation Further Amendment Act 1995 (NSW), Schedule 6, made further refinements, clarifying the retrospective reach and ensuring the "always had effect" language applied from 1963. The amendments were justified in the Second Reading Speech as necessary to protect the revenue against "windfall" claims and to restore the fiscal assumptions on which State budgets had been prepared for decades.

No substantive amendments have been made since 1995. The Act has remained stable because its broad drafting has proved effective in defeating the wave of post-Ha and post-Roxborough claims. Minor technical amendments to cross-references have occurred, but the core policy remains unchanged.

The leading case interpreting the 1993 amendments is State of New South Wales v Commonwealth (No 2) litigation and the subsequent British American Tobacco Australia Services Ltd v Cowell (2002) 7 VR 524 (though that was Victorian legislation). In New South Wales, the Court of Appeal in Gersbach v Gersbach is not relevant; rather, the key authorities are Roxborough itself (which considered the Victorian analogue) and Woolwich Equitable Building Society v IRC principles as modified by statute.

In Commissioner of State Revenue (Vic) v Royal Insurance Australia Ltd (1994) 182 CLR 51 the High Court considered analogous Victorian provisions. The New South Wales Parliament deliberately drafted s 3 more broadly to overcome the limitations exposed in that litigation. The "non-legislative change of the law" concept has been tested in several unreported decisions where taxpayers argued that a change in High Court doctrine on s 90 of the Constitution was "legislative" because it gave effect to the Constitution. Courts have consistently rejected that argument, treating constitutional interpretation as non-legislative.

Controversy persists around the constitutional validity of the retrospective extinguishment. Academics have questioned whether a State can, consistently with Chapter III of the Commonwealth Constitution, extinguish a cause of action that had accrued and was the subject of pending proceedings. The "always had effect" language in s 7(4) and (5) is an attempt to deem the cause of action never to have existed, but the High Court has not yet ruled definitively on whether such deeming can survive a constitutional challenge where federal jurisdiction has been invoked.

Another live controversy concerns the interaction with the Kable doctrine. Because the Act directs courts to treat certain accrued rights as extinguished, arguments have been raised that it substantially impairs the judicial process. To date these arguments have not succeeded at appellate level.

Most practitioners still treat the Act as a simple limitation statute. It is not. Section 5 extinguishes the right itself, so a claimant who discovers a constitutional invalidity 20 years later has no cause of action at all. The "non-legislative change" bar in s 3 is wider than many realise: it catches any shift in "what is generally perceived to be the state of the law". A favourable obiter dictum in an appellate judgment can trigger the bar.

The passing-on test in s 4 is extraordinarily difficult to satisfy. Courts have accepted econometric evidence, but the burden remains on the claimant to prove a negative—that it absorbed the cost and did not raise prices. In competitive markets this is almost impossible without internal management accounts prepared contemporaneously with the payment. The extension to "will not charge to or recover from" any other person means that even a future price adjustment can defeat the claim.

The retrospective provisions in s 7 can produce the startling result that a refund claim that was arguable in 1992 became statute-barred with retrospective effect in 1993. Practitioners acting on historical reviews must run two parallel analyses: the law as it stood at the time of payment, and the law as retrospectively declared.

Section 6's characterisation as substantive law means the Act can apply even where the substantive taxing law is Commonwealth law picked up in federal jurisdiction—an outcome that surprises many federal practitioners. Finally, because "taxation legislation" includes regulations and individual provisions, a successful challenge to a single regulation can trigger the s 3 bar for all payments made before the successful challenge, even if the parent Act remains valid.

Compliance for taxpayers is largely about timely action and meticulous record-keeping. Any business that pays significant State imposts should implement a tax-recovery register that flags potential overpayments within days, not months. Because the 12-month period in s 2(1)(b) runs from payment, automated systems must trigger legal review immediately upon remittance.

To preserve passing-on rights, businesses should maintain two sets of records: (1) pricing decisions that expressly exclude tax absorption, and (2) customer invoices that separately identify the tax component. Paradoxically, clear itemisation helps the Commissioner but may assist the taxpayer in proving the economic incidence. The s 4(1) onus requires positive evidence of non-passage; silence is fatal.

For government agencies, compliance involves pleading the Act at the earliest opportunity. Defence pleadings should expressly rely on ss 2, 3, 4 and 5 and seek orders that the right has been extinguished under s 5. Where a specific refund scheme exists under other legislation, agencies must verify that the scheme satisfies both limbs of s 2(2) before conceding that the Recovery of Imposts Act is disapplied.

In transactional due diligence, acquirers should obtain warranties that no refund claims have been or could be made in respect of the target’s tax history after applying the Act. Tax opinions should expressly address the non-legislative change bar and the characterisation of any anticipated High Court or Court of Appeal decision as non-legislative.

Finally, because the Act is substantive, choice-of-law clauses in contracts and dispute resolution clauses should be drafted to ensure New South Wales law governs both the taxing obligation and any restitutionary claim. Failure to do so may allow a claimant to argue that the Recovery of Imposts Act does not travel with the cause of action.

In practice, the only reliable method of "complying" with the Act from a taxpayer perspective is to avoid overpaying in the first place through robust advance rulings, private binding rulings and real-time compliance programs. Once the money has left the bank account, the window for recovery is narrow, the evidentiary hurdles high, and the statutory bars formidable.
