Dust Diseases Act 2005

The Act primarily affects three groups: injured persons and their dependents, defendants (typically former employers or occupiers), and insurers.

An "injured person" is defined in s 3 as a person who is suffering from, or who has suffered from, a dust disease. Because the definition of dust disease action expressly includes claims for the death of a person as a result of a dust disease, the Act also reaches the estates and dependents of deceased victims. Any South Australian resident (or, given the jurisdictional rules, potentially non-residents whose claims are brought in South Australia) who can assert a breach of duty causing or contributing to a dust disease falls within the protective scope of the procedural advantages.

Defendants are broadly defined in s 3 to include third parties against whom contribution is sought. The presumptions in s 8(2) are particularly relevant to entities that carried on "prescribed industrial or commercial process[es]" capable of generating asbestos dust. This captures a wide range of historical employers in mining, manufacturing, construction, shipbuilding and automotive repair sectors. The mandatory exemplary damages rule in s 9(2) is triggered by actual or constructive knowledge of risk, thereby exposing defendants with historical knowledge of asbestos hazards to additional liability.

Insurers are directly affected by s 11. Where a defendant is unavailable through death, dissolution, insolvency or disappearance, a plaintiff may elect to sue the insurer directly. The insurer inherits the defendant's rights, powers, duties and liabilities (s 11(2)) but its exposure is capped at the indemnity limit that would have applied (s 11(3)). This mechanism prevents plaintiffs from being left without recourse when corporate defendants have ceased to exist.

The South Australian Employment Tribunal and the District Court are statutorily required to apply the priority, evidentiary and damages rules. Legal practitioners appearing in dust disease actions must master the distinct procedural and evidentiary landscape, including the ability to tender prior findings and the costs consequences of refusing formal admissions.

Finally, because s 4A(4) and (5) permit joinder of ancillary or related claims, the Act can affect parties to disputes only tangentially connected to the dust disease, such as family law or statutory benefit recovery matters that can be bundled into the same proceeding.

The Act creates few new substantive duties but significantly recalibrates procedural rights and evidentiary burdens.

Plaintiffs gain a suite of rights: the presumption of causation under s 8(1), the presumption of knowledge under s 8(2), the right to rely on evidence and findings from earlier proceedings (s 8(3)(a) and s 8(4)), the right to split damages awards (s 9(1)), the entitlement to exemplary damages where the statutory criteria are met (s 9(2)), and the right to recover for loss of domestic capacity as a distinct head (s 9(3)). They may also commence directly against insurers under s 11 and benefit from statutory priority under s 5.

Defendants retain the ability to rebut the s 8 presumptions by proof to the contrary. They are entitled to have contribution and apportionment questions determined only after the plaintiff's claim is resolved (s 10), protecting them from premature exposure of their internal disputes. Insurers sued directly under s 11 enjoy the same defences the absent defendant would have had.

Both sides are subject to the facilitative powers in s 8(3)(b) and (c). The court or tribunal may dispense with proof of undisputed matters and may draw adverse costs consequences from a party's refusal to admit formal or peripheral facts. This creates a practical duty to conduct litigation cooperatively on non-contentious issues.

SAET is given exclusive jurisdiction over dust disease actions by s 4A, subject to the appeal rights preserved in s 11A. The District Court retains concurrent operation for those matters not routed to SAET. The obligation in s 5 to give priority directions is cast in mandatory language ("will give the necessary directions"), creating a statutory duty on the judiciary.

The transitional provision in Schedule 1, cl 4(1) extends all these rights and duties to accrued causes of action, subject only to the limited exception in cl 4(2) for actions where trial had already commenced.

The Act is not a regulatory statute and contains no criminal offences or administrative penalties. Enforcement occurs through the civil justice system, with two notable financial mechanisms.

First, s 9(2) requires the District Court or SAET to award exemplary damages where the defendant possessed the requisite knowledge of risk and of the link between asbestos dust and disease. Because the provision uses the word "must", the award is mandatory once the factual predicates are satisfied. The statute does not prescribe a method of calculation, leaving quantum to judicial discretion within the bounds of established principles governing exemplary damages. This operates as a significant deterrent and compensatory uplift for plaintiffs.

Second, the costs rules in s 7 interact with the admission power in s 8(3)(c). A party who declines to admit formal or peripheral facts may have the costs of proving those facts awarded against it. While not a penalty in the strict sense, this creates a financial disincentive to unreasonable litigation conduct. Costs in dust disease actions are otherwise aligned with the District Court scale (s 7(1) and (7)(1a)), with a discretion to apply the Magistrates Court scale where the amount in controversy falls within that court's limits (s 7(2)).

Enforcement of judgments against insurers under s 11 follows ordinary execution processes, subject to the statutory cap in s 11(3). Contribution proceedings between tortfeasors or insurers are deferred until after the primary claim is resolved (s 10), ensuring that enforcement against the plaintiff occurs first.

Because the Act applies to historical causes of action (Schedule 1, cl 4), enforcement can reach long-dormant insurance policies and corporate successors, provided the statutory conditions for direct insurer actions are met.

The Dust Diseases Act 2005 was enacted as principal legislation that amended several related statutes, as recorded in the legislative history: the Civil Liability Act 1936, the Limitation of Actions Act 1936, and the Survival of Causes of Action Act 1940. Although the precise amendments are not reproduced in the supplied text, the existence of those amendments indicates deliberate integration with the general law of negligence, limitation periods and survival of actions.

The most prominent current interaction is with the South Australian Employment Tribunal Act 2014. Section 4A assigns dust disease jurisdiction to SAET and designates the South Australian Employment Court as the decision-making arm. Section 11A expressly displaces Part 5 of the South Australian Employment Tribunal Act 2014 in respect of appeals, substituting a bespoke pathway: interlocutory orders to a single Supreme Court Judge and other decisions to the Court of Appeal (as amended by the Supreme Court (Court of Appeal) Amendment Act 2019). This creates a hybrid judicial–tribunal model unique to dust disease litigation.

The Act also intersects with the general law of evidence and procedure. The power to admit prior findings (s 8(4)) and earlier evidence (s 8(3)(a)) operates as a statutory exception to the hearsay and res judicata rules that would otherwise apply. The presumption provisions in s 8(1) and (2) reverse the ordinary onus of proof on causation and knowledge.

Section 9(3) interacts with the law of damages by mandating a separate head for loss of domestic services, expressly to restore the effect of the principle discussed in the statutory note. This overrides any contrary common-law development that had restricted such claims.

Because s 4A(4) and (5) permit inclusion of non-dust-disease claims, the Act interacts with whatever substantive law governs those ancillary matters, whether contractual, statutory or equitable. The transitional provision in Schedule 1 ensures that these interactions apply to both new and accrued claims, subject to the trial-commenced carve-out.

Finally, the regulation-making power in s 12 allows the Governor to fill any gaps by subordinate legislation, although no specific regulations are reproduced in the text.

The legislative history records two tranches of amendments material to the current text. The Statutes Amendment (South Australian Employment Tribunal) Act 2016 (No 63 of 2016) effected a wholesale transfer of jurisdiction from the District Court to SAET. It inserted s 4A, amended s 5, deleted the former s 6, inserted s 7(1a), amended ss 8, 9 and 10, and inserted s 11A. These changes took effect on 1 July 2017. The evident purpose was to align dust disease litigation with the new specialist industrial and employment tribunal structure, presumably to capitalise on SAET's expertise in expeditious dispute resolution and to centralise asbestos-related claims in one forum.

The Supreme Court (Court of Appeal) Amendment Act 2019 (No 45 of 2019) further refined s 11A with effect from 1 January 2021. It adjusted the appeal destination for non-interlocutory decisions to the newly constituted Court of Appeal, ensuring consistency with the broader appellate reforms.

The transitional provision in Schedule 1, cl 4 was retained throughout, maintaining the Act's retrospective reach. No amendments altered the core presumptions in s 8 or the mandatory exemplary damages rule in s 9(2). The changes therefore represent institutional and procedural refinement rather than substantive policy reversal. They respond to the creation of SAET and the reorganisation of the Supreme Court, ensuring the original object in s 4 continues to be delivered through the most appropriate modern institutions.

The provided text contains no reported decisions construing the Act. The only judicial reference appears in the note to s 9(3), which states that the subsection is intended to restore the effect of Sullivan v Gordon (1999) 47 NSWLR 319. This note signals legislative dissatisfaction with subsequent common-law developments that had curtailed recovery for loss of domestic capacity and constitutes the sole explicit acknowledgment of controversy addressed by the statute.

Because the presumptions in s 8(1) and (2) reverse the ordinary burden of proof, they are structurally likely to generate dispute over the threshold required to "establish" exposure "in circumstances in which the exposure might have caused or contributed" to the disease. The phrase "in the absence of proof to the contrary" invites defendants to adduce epidemiological or medical evidence rebutting causation in individual cases. The text supplies no guidance on the standard or sufficiency of such rebuttal evidence.

Section 8(4)'s power to adopt findings from other Australian courts or tribunals raises questions of procedural fairness. A party adversely affected must satisfy the decision-maker that a corresponding finding is "inappropriate to the circumstances of the present case". The statute does not prescribe the criteria for that assessment, leaving scope for argument about the weight to be given to prior reasons, differences in medical evidence, or changes in scientific understanding.

The mandatory language of s 9(2) ("must … award … exemplary damages in each case") is apt to provoke controversy where a defendant argues that the knowledge requirement is not met on the facts, or that an award would be disproportionate. The absence of a statutory cap or formula for quantification leaves the provision open to constitutional arguments about judicial power, although the text itself does not record any such challenge.

The direct action against insurers under s 11 may generate disputes over whether the defendant is in fact "insolvent" or "cannot be found", and over the precise scope of the indemnity that would have been available. Section 11(3) expressly limits the insurer's liability to the notional indemnity, inviting coverage disputes to be litigated within the dust disease action itself.

The interaction between the statutory priority direction in s 5 and the ordinary case management powers of the District Court and SAET has the potential to create satellite litigation about what constitutes "the proper administration of justice" in any given listing.

Because the text contains no actual decisions, these observations are derived strictly from the structural features and wording of the provisions themselves.

Most practitioners assume that dust disease litigation follows ordinary civil procedure; the Act's evidentiary presumptions and mandatory exemplary damages rule upend that assumption. The s 8(1) presumption is triggered by exposure that "might have caused or contributed" to the disease—a remarkably low threshold that many defendants fail to appreciate until after the presumption has arisen. Once engaged, the defendant bears the full evidentiary onus of disproving causation, often requiring expensive expert epidemiological evidence that may still fail against a sympathetic tribunal.

The mandatory exemplary damages obligation in s 9(2) is frequently overlooked. The word "must" leaves no discretion once the two limbs of knowledge are satisfied. Historical documents showing corporate awareness of asbestos risks can therefore convert an ordinary damages claim into one carrying a substantial punitive component without further proof of reprehensible conduct.

Section 11's direct insurer action contains a subtle trap: the insurer inherits the absent defendant's rights and liabilities, including any limitation defences that may have been available. However, because the Act applies to causes of action arising before commencement (Schedule 1, cl 4), practitioners must check whether the 2016 or 2019 amendments interact with limitation periods preserved by the earlier amendments to the Limitation of Actions Act 1936.

The power to adopt prior findings under s 8(4) is more potent than it first appears. A single favourable judgment against a major insurer or former employer can be leveraged across dozens of subsequent claims. Defendants must therefore treat every case as potentially precedent-setting and consider the strategic cost of allowing an adverse finding to crystallise.

Few realise that s 4A(4) and (5) permit joinder of entirely unrelated heads of claim provided they arise from the same cause of action. This can bring family provision claims, statutory benefit recovery actions or even contractual disputes into the SAET forum, exposing parties to a tribunal whose ordinary caseload is industrial rather than general civil litigation.

The costs discretion in s 7(2) is rarely invoked but can produce dramatic swings: a modest claim within Magistrates Court limits may still attract District Court costs if the tribunal considers the matter sufficiently complex. Conversely, a party who refuses a formal admission under s 8(3)(c) can find itself paying costs on an indemnity basis for discrete issues that ought to have been conceded.

Finally, the appeal pathway in s 11A is a statutory override of the general SAET appeal regime. Many practitioners still brief appeals as though they lie to the Full Court of the Supreme Court; only the Court of Appeal (post-2021) or a single Judge for interlocutory matters is competent. Filing in the wrong forum risks limitation and jurisdictional objections.

Compliance for plaintiffs' lawyers consists in promptly identifying dust disease actions, gathering the minimal material necessary to engage the s 8 presumptions, and pressing for priority directions under s 5. Pleadings should expressly plead the statutory presumptions and, where appropriate, the criteria for exemplary damages. Where the defendant is unavailable, early investigation of historical insurance policies is essential to invoke s 11.

For defendants and their insurers, compliance begins with a realistic assessment of the s 8 presumptions. Internal reviews of historical documents should be conducted early to determine whether the knowledge limb of s 9(2) can be contested. Where multiple parties are involved, care must be taken not to press for simultaneous determination of contribution issues in breach of s 10. Formal and peripheral admissions should be made promptly to avoid adverse costs orders under s 8(3)(c).

Insurers facing direct actions must assemble the full defence that the absent defendant would have been entitled to advance, while remaining alert to the statutory cap on liability. All parties should consider whether ancillary claims can or should be joined under s 4A(4) and (5) to avoid parallel proceedings.

At the institutional level, SAET and the District Court must maintain listing practices that give genuine priority to these matters. Judicial officers should develop familiarity with the s 8(4) mechanism so that prior findings are admitted only after proper consideration of the "inappropriate to the circumstances" test.

Corporate defendants in industries with historical asbestos exposure should maintain registers of potential claims and review insurance coverages that may be triggered decades after policy inception. Risk management now includes ensuring that any new industrial processes cannot generate asbestos dust and that safety documentation clearly records knowledge (or lack of knowledge) of hazards so as to manage future s 8(2) and s 9(2) exposure.

Finally, because the Act applies retrospectively, compliance requires auditing of closed files and legacy liabilities. Legal teams should maintain precedent banks of prior findings that may be deployed or defended against under s 8(3) and (4). Regular training on the mandatory exemplary damages rule and the split-award mechanism in s 9 is essential for both plaintiff and defendant practitioners.

By adhering closely to the statutory language—particularly the precise triggers for presumptions, the sequencing rule in s 10, and the appeal pathway in s 11A—parties can avoid the procedural pitfalls that the Act was designed to eliminate for plaintiffs while protecting the legitimate forensic interests of defendants.
