Motor Vehicle and Workplace Accidents (Catastrophic Injuries) Act 2016

The Act structures a classic no‑fault, state‑administered care‑and‑support system for defined catastrophic injuries, paired with a set of substantive offsets to private damages and a regulatory architecture for assessment, provider registration and payment. Key statutory concepts are defined and connected across Parts 1-7.

Catastrophic injury and scope:

• “Catastrophic injury” is defined by reference to prescribed criteria (s 3 definition; see s 8(1) which ties eligibility to a person suffering a catastrophic injury that is a motor vehicle injury or workplace injury to which the Act applies). The Act does not itself list the clinical thresholds; it leaves the criteria to prescriptions in regulations. The motor vehicle scope is limited to incidents “caused by or arising out of the use of a motor vehicle” as defined in s 4(1)-(2), with exclusions for negligence liability (s 5(3)), private land (s 5(4)) unless an insured interstate vehicle is involved, motor sports events (s 5(5)(a)) and terrorist acts (s 5(5)(b)). Workplace injury coverage is conditional on an established entitlement to workers’ compensation under the Workers Compensation and Injury Management Act 2023 (s 5A(2)-(3)) and is deferred until a specified commencement provision in that Act comes into operation (s 5A(1)).

Treatment, care and support needs:

• The statutory concept of “treatment, care and support needs” is a defined multi‑category list in s 6(1), including medical and dental treatment, rehabilitation, ambulance, respite, domestic assistance, attendant care, aids and appliances, prostheses, education and vocational training, home and transport modification, and any other types approved by the Commission (s 6(1)(a)-(l)). The Act contemplates excluded needs that can be prescribed (s 3 definition of excluded treatment, care and support needs; s 6(2)) and allows the Commission to approve additional categories (s 6(1)(l)).

Assessment and standard:

• The Commission must assess participants’ needs (s 15(1)). Assessments are to identify those needs that “are necessary and reasonable in the circumstances” and that “relate to” the injury (s 15(2); s 18(2) repeats the necessary/reasonable standard for payments). The Act requires written notification of the assessment and reasons (s 15(3)). The regulations are given detailed power to set procedures, intervals, methods, criteria and requirements to undergo medical examinations (s 16).

Participation categories:

• Participation is bifurcated into “interim participant” and “lifetime participant” statuses (ss 8-12). Regulations may specify criteria for each status (s 8(2)). The Commission can accept applicants and must notify acceptance (s 10). Interim participation is time‑limited by regulation (s 11(1)); if the Commission becomes satisfied during interim participation that a person is eligible for lifetime participation, the person must be accepted as a lifetime participant (s 12(1)). Notably, for damages purposes the legislation treats interim participants as if they will become lifetime participants for future care ( Civil Liability Act insertion s 13A(6) and Motor Vehicle (Third Party Insurance) Act s 3EA(6) and s 3FB implications).

Payments and limits:

• The Commission is the payer: it “must pay for all necessary and reasonable expenses” for assessed needs while the person is a participant (s 18(1)). The Act preserves regulatory control over monetary or other limits, criteria for necessity and reasonableness, and mechanisms for payment (s 18(4)(a)-(c)). Section 20 specifically allows regulations to fix maximum amounts for fees for medical, dental, rehabilitation and attendant care services and for private hospital fees, including by reference to prescribed schedules or persons (s 20(5)-(6)). The Commission may, by agreement, make lump‑sum payments to cover expenses for a fixed period rather than pay as incurred (s 18(5)).

Provider registration and standards:

• The Commission may register specified persons or classes as registered providers for services prescribed in the regulations (s 23(1)). A register must be kept (s 23(2)). Regulations can set competency standards and application matters; registration may be conditional, varied or revoked (s 23(4)-(7)). Breach of registration condition carries a $10,000 fine (s 23(6)).

Offsets to private damages and substantive law:

• The Act, via amendments to the Civil Liability Act 2002 and the Motor Vehicle (Third Party Insurance) Act 1943, restricts damages in cases where CISS payments are received or the person is a participant (Civil Liability s 13A inserted by s 38; Motor Vehicle Act s 3EA inserted by s 45). These provisions deny awards for treatment, care and support needs that are the subject of CISS participation (s 13A(5) Civil Liability Act; s 3EA(4) Motor Vehicle Act) and make the restrictive provisions part of the substantive law applied by courts (Motor Vehicle Act s 3FA inserted by s 46). Section 3FB (s 46) additionally disapplies contributory negligence deductions in determining damages for future care where catastrophic injury is involved (s 3FB(3)).

Reporting, disclosure and immunity:

• Hospitals may notify and disclose relevant information to the Commission when a patient is admitted with an injury that is, or is reasonably believed to be, catastrophic; disclosures in good faith attract statutory protection from civil or criminal liability and are not to be regarded as breaches of confidentiality or professional standards (s 30(2)-(3)). WorkCover WA, licensed insurers or self‑insurers may disclose relevant information about an injured worker to the Commission if the injury appears likely to be catastrophic, and insurers have express obligations to provide claim details, medical reports and to notify the Commission within seven days after liability to pay compensation has been accepted (s 30A(3)-(4)). A worker who elects to retain rights to damages under the workers’ compensation regime or who receives damages that include future care must notify the Commission within seven days (s 30A(5)).

Regulation and guidelines:

• The Act confers broad regulatory power (s 34), permits the adoption by reference of codes and subsidiary legislation in regulations (s 35), and allows the Commission to issue non‑legislative guidelines which must be published and considered by persons exercising functions under the Act (s 33).

Funding and insurance architecture:

• The Insurance Commission Act is amended to create the Motor Vehicle (Catastrophic Injuries) Fund and to state sources and permitted uses (s 41 new s 16(3)). The Motor Vehicle (Third Party Insurance) Act is amended to treat a policy complying with that Act as also insuring a person against the risk of suffering a catastrophic injury that results from a motor vehicle accident, to the extent the insurance funds payments under the CISS for assessed needs (s 50 inserted s 6A). Vehicle licence issuance/renewal is linked to payment of premiums determined by the Commission (s 48 amending s 4 and inserting 4(8A)-(8B)).

Taken together, the Act couples an administrative assessment-and-payment machinery with regulatory levers over provider standards, pricing limits, information flows, and a set of substantive legal offsets in private tort damages. Many critical details are reserved to regulations or Commission policy (eg, eligibility criteria, excluded needs, fee schedules, provider competencies), creating implementation discretion and rule‑making points that will materially shape coverage and cost outcomes.

The Act creates direct obligations and rights for a defined set of actors and indirect effects for adjacent sectors. Identifiable affected parties in the statutory text include the following.

Injured persons and potential participants:

• Individuals who suffer a motor vehicle injury in Western Australia on or after the operative date, provided the injury meets the statutory definition of motor vehicle injury and the prescribed catastrophic criteria, may apply to participate in the CISS (ss 4, 5, 8, 9). For workplace injuries, the Act applies only after the relevant Workers Compensation Act provision commences and only where there is an established entitlement to compensation under that Act (s 5A(1)-(3)); a residency rule bars persons from applying in respect of workplace injuries unless they reside in Australia at the time of application (s 9(1A)) and suspends participation while absent (s 14(1A)). Particular exclusions apply (eg, motor sports events s 5(5)(a), terrorist acts s 5(5)(b), private land unless insured vehicle involved s 5(4)).

Participants have procedural rights to apply, be assessed and to receive written reasons for assessments (ss 9, 15(3)), and rights to seek internal review and, in limited circumstances, appeal to the District Court (Part 5, ss 24-27). Participants also have obligations under the Act: to comply with assessment requirements (s 16(2)(d) authorises requirements to undergo medical examinations), to refrain from providing false or misleading information (s 31), and to notify the Commission in particular circumstances for workplace injury cases (s 30A(5)).

Insurance Commission of Western Australia (the Commission):

• The Commission gains a central administrative and financial role. It must assess participants’ needs (s 15), pay for assessed needs (s 18), register and maintain a register of providers (s 23), issue guidelines (s 33), and administer the dedicated Motor Vehicle (Catastrophic Injuries) Fund created by amendments to its Act (s 41 new s 16(3)). The Commission is not liable for participants’ legal costs in assessment proceedings (s 17). The Commission is empowered to suspend participation in prescribed circumstances (s 14(2)) and to recover payments from interstate insurers in particular situations (s 21).

Insurers and vehicle owners/licensees:

• The Motor Vehicle (Third Party Insurance) Act changes impose a funding architecture. The Commission determines “the appropriate insurance premium” that must be paid before a vehicle licence is granted or renewed, meaning licensees must pay that premium as a precondition to licensing (s 48 new ss 4(8)-(8A)). The policy thereby taken to exist under the Motor Vehicle Act is treated as insuring injured persons to the limited extent of making payments under the CISS for assessed needs (s 50 new s 6A(2)-(3)). The Motor Vehicle Act amendments also create offences for false or misleading information and obstruction (ss 27B-27C) with fines of up to $10,000, mirroring ss 31-32 of the CISS Act.

Hospitals, clinicians and registered providers:

• Hospitals may notify the Commission and disclose relevant medical information when a patient is admitted with an injury that is or is reasonably believed to be catastrophic; such disclosures attract statutory protection from civil or criminal liability if made in good faith (s 30(2)-(3)). The Commission may register providers for particular services identified by regulation and may set competency standards and conditions (s 23). If a service that must be provided by a registered provider is instead provided by an unregistered person, the Commission is not required to pay for that service (s 19(2)(d)).

WorkCover WA, licensed insurers and self‑insurers:

• For workplace injuries, WorkCover WA, licensed insurers and self‑insurers may disclose relevant information about an injured worker to the Commission if the injury is or appears likely to be catastrophic (s 30A(3)). Insurers and self‑insurers must provide claim details and medical reports and must notify the Commission within seven days of acceptance of liability (s 30A(4)). These obligations create a mandatory data flow to the Commission for potential CISS cases.

Legal practitioners and courts:

• The Act alters the damages landscape. The Civil Liability Act amendment (s 13A inserted by s 38) and Motor Vehicle (Third Party Insurance) Act amendments (s 3EA, s 3FA, s 3FB) restrict awards for treatment, care and support needs where CISS involvement exists and make those restrictions part of the substantive law to be applied by courts. The District Court is given limited appeal jurisdiction in relation to eligibility decisions and certain issues about whether an incident is a motor vehicle accident (s 27). The Commission is expressly not liable for costs for participant legal services in relation to assessments (s 17), affecting funding for legal representation in assessment disputes.

The State and Crown:

• The Act binds the State (s 7) and creates funds and appropriations structures inside the Insurance Commission Act amendments (s 41 new s 16(3)) to hold and apply moneys for CISS functions (s 41(3)). The Act also contains no‑contracting‑out provisions (s 29), preventing private agreements from removing statutory entitlements or obligations.

Other affected entities:

• Employers and self‑insurers, provider organisations, private hospitals, vehicle licensing authorities (Director General), and bodies that publish fee schedules or act as prescribed persons for fee references under s 20 are affected. Regulations may adopt external codes or schedules (s 35) and may set fee caps by reference to a prescribed person or schedule (s 20(6)), which will affect providers’ pricing and fee negotiations.

Who pays, and who decides:

• The Commission pays for assessed needs while a person is a participant (s 18). The Commission decides eligibility, assessment outcomes and, under the regulations, suspension of participation (ss 8-16, 14). For funding, premiums determined by the Commission must be paid before vehicle licences are issued or renewed (s 48). The Motor Vehicle (Catastrophic Injuries) Fund holds moneys dedicated to CISS purposes (s 41 new s 16(3)).

Behavioural changes the Act creates:

• Injured persons facing catastrophic needs may seek CISS participation rather than litigate for future care, subject to the eligibility and damages interaction rules (s 8(3), Civil Liability s 13A). Hospitals and insurers are incentivised to report early to the Commission because statutory disclosure provides liability protection and because insurers must notify within defined timeframes (s 30; s 30A(4)). Providers must seek registration for services identified by regulation if they expect Commission payment (s 23). Vehicle licence applicants must pay the Commission’s premium to obtain licensing (s 48), making vehicle owners the primary contributory population to the Fund.

In short, the Act affects injured people, the Commission as payer/administrator, insurers and licensees as funders through premium architecture, providers as regulated suppliers, hospitals and compensation insurers as information reporters, and courts and legal advisers by altering the substantive and procedural law of damages for catastrophic injury.

The Act allocates specific decision‑making powers to the Commission, establishes participant entitlements and procedural safeguards, and creates compliance obligations for hospitals, insurers and providers. Below are the principal statutory duties and rights, with section references.

Commission duties and powers:

• Administer and manage the CISS: The Commission is expressly assigned this function by amendment to the Insurance Commission Act (s 40, inserting s 6(aa)). It must assess all participants’ treatment, care and support needs (s 15(1)) and notify the participant of the assessment and the reasons for the findings (s 15(3)).
• Payment obligation: The Commission “must pay for all necessary and reasonable expenses incurred by or on behalf of a person in relation to the person’s assessed treatment, care and support needs while the person is a participant” (s 18(1)). The Commission’s liability is circumscribed by exclusions, regulatory criteria and monetary limits the regulations may set (s 18(3)-(4); s 20).
• Register and regulate providers: The Commission may register specified persons or classes as registered providers for services identified in the regulations, must maintain a register and may impose, vary or revoke registration conditions in accordance with regulations (s 23(1)-(7)).
• Guidance and publication: The Commission may issue guidelines, must publish them on a website, and persons with functions under the Act must have regard to them (s 33(1)-(4)).
• Suspension powers: The Commission may suspend a person’s participation while that person is absent from Australia if the person is a motor vehicle participant (s 14(1)) and must suspend participation in workplace cases while the person is absent (s 14(1A)). Regulations may prescribe further suspension powers (s 14(2)).
• Recovery and cost control: The Commission may recover amounts paid if it becomes clear the Act does not apply because the motor vehicle owner/driver incurred negligence and the motor vehicle was an interstate vehicle (s 21). The Commission may also agree lump‑sum payments in place of pay‑as‑you‑go payments (s 18(5)).

Participant rights and obligations:

• Application and acceptance: Injured persons may apply to become participants in the CISS in the manner and form determined by the Commission and accompanied by requested information (s 9(1)-(2)); the Commission must accept an eligible applicant and notify acceptance in writing (s 10(1)-(2)).
• Assessments and reasons: Participants have the right to an assessment of their needs and to written notice of the assessment and reasons (s 15(1), (3)).
• Review and appeal: Participants may apply for review of eligibility decisions and assessments in accordance with regulations (ss 25-26). Appeals to the District Court are available for specified questions, including whether an incident is a motor vehicle accident or whether an injury is a motor vehicle or workplace injury to which the Act applies; leave is required to appeal review decisions and the District Court will only grant leave where a question of law is involved (s 27(2)-(4)).
• Compliance obligations: Participants must comply with assessment procedures and may be required to undergo medical examinations under regulations (s 16(2)(d)). They must not provide false or misleading information to the Commission (s 31), and participation is suspended if they are absent from Australia in certain workplace cases (s 14(1A)).

Hospitals and health professionals:

• Notification and disclosure: The person in charge of a hospital or authorised staff may notify and disclose relevant information to the Commission when a patient is admitted with an injury that is or is reasonably believed to be catastrophic (s 30(2)). Such notifications and disclosures in good faith are protected from civil or criminal liability and are not to be treated as breaches of confidentiality, professional ethics, or employment conduct rules (s 30(3)(a)-(b)).
• Health professional definitions: The Act adopts national law definitions for health professions and health professional registration for examinations (s 3; as replicated in the Motor Vehicle Act amendment s 53 replacing its s 30).

Insurer and WorkCover obligations (workplace cases):

• Disclosure and notification: WorkCover WA, licensed insurers and self‑insurers are authorised to disclose relevant information to the Commission (s 30A(3)). An insurer or self‑insurer that has received a claim for a likely catastrophic injury must provide claim details and copies of medical reports and must notify the Commission within seven days after liability to pay compensation has been accepted or determined (s 30A(4)).
• Worker obligations: A worker who elects to retain a right to damages or who receives damages that include an amount for future treatment, care and support must notify the Commission within seven days (s 30A(5)).

Provider duties:

• Registration compliance: Registered providers must not contravene registration conditions without reasonable excuse (s 23(6)); contraventions attract a fine of $10,000. The Commission may vary or revoke registration in accordance with regulations (s 23(7)).
• Fee compliance: Providers delivering services to participants may be paid only up to regulatory caps or under schedules adopted in regulations (s 20(5)-(6)); payments must be made consistently with those regulations (s 20(7)).

Legal costs and representation:

• Commission not liable for legal costs for assessment: The Commission is not liable for legal costs incurred by a participant in relation to treatment, care and support assessments (s 17). The regulations may make provision for liability in respect of legal costs in dispute resolution proceedings (s 28(f)).

Damages and substantive offsets:

• Restrictions on damages: If a person is a participant in the CISS, no damages are to be awarded in respect of treatment, care and support needs that arise during the period of participation or that will or may arise in future (Civil Liability Act s 13A(5) inserted by s 38). Similar restrictions appear in the Motor Vehicle (Third Party Insurance) Act via ss 3EA and 3FA, and courts are directed that these restrictive provisions form part of the substantive law applicable to motor vehicle damage claims (s 46 inserting s 3FA). The Motor Vehicle Act s 3FB further directs that when awarding damages for catastrophic injury, no deduction is to be made for contributory negligence in respect of future treatment, care and support needs (s 46, new s 3FB(3)).

Offences and penalties:

• False or misleading information attracts a fine of $10,000 (s 31).
• Obstruction of a Commission officer in the performance of functions attracts a fine of $10,000 (s 32).
• Registered provider contravention of registration conditions is a fine of $10,000 (s 23(6)).
• Regulations may prescribe offences with penalties not exceeding a $10,000 fine (s 34(2)(d)). The Motor Vehicle Act mirrors the false/misleading and obstruction offences and penalties (ss 27B-27C).

In essence, the Commission is the decision maker and payer, participants are entitled to assessments and payments for assessed needs but face exclusions and obligations, hospitals and insurers have reporting duties and protections, and providers must meet registration and fee constraints to be eligible for payment.

The Act creates specific criminal‑style sanctions (fines) and a range of administrative enforcement levers. Enforcement is split between monetary penalties for non‑compliance with information and registration obligations, and administrative remedies the Commission may use to control participation and recover payments. The Motor Vehicle (Third Party Insurance) Act amendments mirror many enforcement mechanisms for interactions with insurance and licensing.

Monetary penalties:

• False or misleading information: A person must not provide false or misleading information under the Act in connection with applications, notices, compliance requirements or any other purpose under the Act (s 31(1)). The prescribed penalty for that offence is a fine of $10,000. The elements include knowingly making false or misleading statements in a material particular, omissions that render statements misleading, and giving information known to be false or misleading in material particulars (s 31(2)). The Motor Vehicle Act inserts a parallel offence at s 27B with the same penalty (s 52).
• Obstruction: A person who obstructs or hinders a Commission officer or other person in the performance of a function under the Act commits an offence, with a fine of $10,000 (s 32(2)). The Motor Vehicle Act inserts an identical obstruction offence at s 27C (s 52).
• Provider registration breach: A registered provider who contravenes a condition of registration without reasonable excuse is liable to a fine of $10,000 (s 23(6)).
• Regulatory penalties: Regulations may prescribe offences with penalties not exceeding a fine of $10,000 (s 34(2)(d)). This gives scope for relatively small regulatory fines for breaches of operational rules.

Administrative enforcement and remedies:

• Suspension of participation: The Commission may suspend a person’s participation while the person is absent from Australia (s 14(1)) if the participant is in respect of a motor vehicle injury; suspension is automatic for workplace injury participants while absent (s 14(1A)). The regulations may give further power to suspend participation in prescribed circumstances such as failure to comply with regulatory requirements (s 14(2)).
• Registration variation and revocation: The Commission may impose, add to, vary or cancel conditions of registration, or revoke a registration, in accordance with regulations (s 23(7)). This is an administrative control over who may deliver Commission‑funded services.
• Recovery of payments: The Commission may recover from an “appropriate person” amounts already paid where it later decides the Act does not apply because the owner or driver incurred negligence and the motor vehicle was an interstate vehicle covered by another jurisdiction’s compulsory scheme (s 21). This creates a statutory right of recoupment in cross‑jurisdictional cases.
• Non‑payment where provider unregistered or contravenes regulations: The Commission is not required to pay for services that must be provided by registered providers if those services are provided by unregistered persons (s 19(2)(d)). The Commission may also elect to decline payment for services provided gratuitously or while a person is absent from Australia (s 19(2)(a)-(b); (5)).
• Civil law offsets and correction: The Civil Liability Act and Motor Vehicle Act amendments effectively remove future care damages from a plaintiff’s claim where CISS applies (Civil Liability s 13A; Motor Vehicle s 3EA). The Motor Vehicle Act declares those restrictive provisions are part of the substantive law and allows a person who has paid more in damages than would have been payable under the restrictive provisions to recover the excess as a debt (s 46, new s 3FA(4)-(5)). This creates a statutory mechanism to prevent double recovery and to correct awards that do not conform to the new rules.

Procedural enforcement and judicial review:

• Reviews and appeals: The Act provides for internal review of eligibility decisions and assessments (ss 25-26) and allows limited appeals to the District Court on questions such as whether an incident is a motor vehicle accident or whether an injury is a motor vehicle or workplace injury to which the Act applies (s 27(2)). Appeals from other review decisions require leave and the court will only grant leave where a question of law is involved (s 27(3)-(4)). Appeals must be commenced within the prescribed time (s 27(5)).

Protections for reporters:

• Good‑faith immunity for hospital disclosures: Where a notification or disclosure is made by a hospital in good faith under s 30(2), no civil or criminal liability is incurred and the disclosure is not to be treated as a breach of confidentiality, professional ethics, or employment conduct (s 30(3)(a)-(b)). This reduces legal risk for early reporting.

Compliance incentives and deterrence:

• The penalty levels are modest relative to the potential financial flows in catastrophic injury care; however, administrative consequences such as suspension, deregistration, non‑payment, and recovery rights create significant economic disincentives. The damages restrictions further alter litigation incentives for claimants and defendants, potentially reducing the incentive for plaintiffs to litigate for future care while shifting funding responsibility to the Commission and the Motor Vehicle (Catastrophic Injuries) Fund.

Implementation enforcement risks and gaps:

• Many substantive details are delegated to regulations and to the Commission’s guidelines (s 16; s 34; s 33). Enforcement efficacy will therefore depend on regulatory detail such as the extent and nature of monetary caps (s 20), the criteria for necessary and reasonable care (s 16(2)(c)), the definition of excluded needs (s 3), and provider registration standards (s 23(4)). Where the regulations are silent or ambiguous, administrative discretion and litigation are likely to follow.

Collectively, the Act combines statutory penalties for information and obstruction misconduct with administrative controls over participation, provider registration, payments and recovery rights in the event of overlap with other jurisdictions or negligence findings. The statutory damages offsets and substantive law declarations form a significant enforcement mechanism by altering private legal entitlement to future care awards.

The Act is expressly designed to interact with, and has been implemented by amendments to, several existing Western Australian statutes. The source text both cross‑references and modifies substantive and procedural regimes in those Acts and incorporates national law definitions. Below are the principal statutory interactions and the mechanisms by which they operate.

Motor Vehicle (Third Party Insurance) Act 1943:

• Numerous amendments to the Motor Vehicle (Third Party Insurance) Act are enacted in Division 3 (ss 43-54). Key interactions:
  • Definitions for assessed treatment, care and support needs, catastrophic injury and CISS are inserted into s 3(1) so the Motor Vehicle Act uses the same terminology as the CISS Act (s 44).
  • Restrictions on damages where CISS payments exist are inserted at s 3EA (s 45) and 3FB (s 46), aligning the Motor Vehicle Act’s damages regime with the CISS coverage and ensuring courts apply the restrictions as the substantive law (s 46 new s 3FA).
  • The Motor Vehicle Act is amended to treat a policy complying with that Act as also insuring an injured person against the risk of suffering a catastrophic injury resulting from a motor vehicle accident, but only to the extent of making payments under the CISS for assessed needs (s 50 new s 6A). This links compulsory third‑party insurance to the CISS payment obligation.
  • Vehicle licensing is tied to payment of the appropriate insurance premium determined by the Commission (s 48 replacing s 4(8) and inserting 4(8A)-(8B)). The licence document is now taken to constitute the issue of a policy complying with the Act (s 48(8A)).
  • The Motor Vehicle Act adopts offences and obstruction provisions mirroring the CISS Act (ss 27B-27C, inserted by s 52), and replaces its examination provisions with the updated health professional framework (s 53).
  • Transitional licensing provisions are provided to account for overlapping commencements (s 54 replacing s 34).

Insurance Commission of Western Australia Act 1986:

• The Insurance Commission Act is amended to give the Commission explicit statutory responsibility to manage and monitor the CISS (s 40 inserting s 6(aa)) and to create a dedicated Motor Vehicle (Catastrophic Injuries) Fund (s 41 amending s 16). The Fund is to consist of moneys appropriated for, or derived from or in connection with, the Commission’s functions under s 6(aa) and related sources (s 41(3)). The Fund is to be applied for those functions only, subject to s 18 (s 41(3)). The Insurance Commission Act hence provides the appropriation and accounting frame for CISS liabilities and reserves.

Civil Liability Act 2002:

• Division 1 (s 37-38) inserts s 13A into the Civil Liability Act restricting damages where the CISS provides or will provide treatment, care and support. Section 13A displaces awards of damages for both past and future treatment, care and support needs where the person is a CISS participant and clarifies assumptions about interim participants and their expectations of lifetime participation (Civil Liability s 13A(5)-(8)). The insertion operates “despite section 12” (s 38(10)), indicating an overriding of other Civil Liability provisions, and aligns private negligence damages outcomes with the CISS payment structure.

Workers Compensation and Injury Management Act 2023:

• Workplace injury coverage under the CISS is explicitly tied to the Workers Compensation Act. Section 5A states that the CISS applies to a workplace injury only if there is an established entitlement to compensation under the Workers Compensation and Injury Management Act 2023 (s 5A(2)-(3)). The Act further provides for residency and suspension rules for workplace cases (s 9(1A), s 14(1A)). The compilation table records the Workers Compensation Act commencement dates; the CISS’s workplace application is therefore staged to follow the workers’ compensation scheme’s implementation.

Health Practitioner Regulation National Law (Western Australia):

• The Act uses the Health Practitioner Regulation National Law (WA) to define “health profession” and “health professional” for the purposes of examinations and assessments (s 3 definitions), and the Motor Vehicle Act amends its examination provision to mirror that definition (s 53 replacing s 30). This integrates national registration standards into the Commission’s power to require medical examinations and to rely on registered professionals for assessments.

Health Services Act 2016 and hospital definitions:

• “Hospital” is given the meaning in the Health Services Act 2016 s 8 for s 30 purposes (s 30(1)). Hospitals are granted regulatory permission to notify and disclose relevant information to the Commission and legal protections for good‑faith disclosures (s 30(2)-(3)).

Interpretation Act and adoption of codes:

• The Act permits regulations to adopt external codes or subsidiary legislation (s 35). If regulations adopt by reference, the Commission must ensure the adopted materials are published on a website (s 35(5)). The Act also confirms guidelines issued by the Commission are not subsidiary legislation for Interpretation Act purposes but must be considered by persons exercising functions (s 33(3)-(4)).

Terrorism (Extraordinary Powers) Act 2005:

• The Act excludes injuries that arise as a result of acts defined as terrorist acts under the Terrorism (Extraordinary Powers) Act 2005 (s 5(5)(b)). This cross‑reference narrows CISS coverage for those factual circumstances.

Other interactions and overriding effects:

• The Act contains a no‑contracting‑out provision (s 29), making the CISS rights and obligations non‑waivable or not capable of being displaced by contract. The Motor Vehicle Act’s s 3FA declaration that the restrictive provisions are part of substantive law is intended to ensure courts of other jurisdictions apply the offsets (s 46). Transitional provisions in the Motor Vehicle Act (s 54) manage overlaps between the Acts at commencement.

In sum, the Act is not standalone: it creates a network of dependencies with insurance, compensation, health, interpretation and motor vehicle licensing statutes. It reconfigures private damages entitlements, ties compulsory insurance and vehicle licensing to the CISS funding model and mandates reporting flows from hospitals and insurers that are subject to protections and time limits. The Act’s substantive reach is therefore realised through both primary text and the web of amendments to existing regulatory regimes.

The compilation sheet and in‑text amendment notes record a sequence of enactments and changes to the primary text. Below are the material amendments and their dates as recorded in the provided source.

Original enactment:

• Motor Vehicle (Catastrophic Injuries) Act 2016 (as originally titled) received assent on 14 April 2016. Sections 1 and 2 commenced on assent day; the rest of the Act commenced on dates fixed by proclamation, with most provisions commencing on 14 May 2016 and s 5 (scope of motor vehicle injury) commencing 1 July 2016 (see compilation table).

Subsequent amendments and notable insertions recorded in the text:

• Legal Profession Uniform Law Application Act 2022 (No. 9 of 2022) s 424 amended s 3 (definitions) and commenced 1 July 2022 (compilation table). This amendment aligns “legal costs” and “legal services” with the Legal Profession Uniform Law (WA) definitions (s 3 edits noted).
• Health Services Amendment Act 2023 Pt 4 (No. 1 of 2023) effected amendments that came into operation on 1 July 2023 (compilation table). Section 20 was amended by No. 1 of 2023 s 92 to add reference to the Private Hospitals and Health Services Act 1927 definitions for private/public hospital in s 20(1).
• Workers Compensation and Injury Management Act 2023 (No. 21 of 2023) inserted workplace injury coverage and associated provisions. In particular, s 5A (workplace injury to which Act applies) was inserted by No. 21 of 2023 s 665 and took effect with the Workers Compensation Act commencement (compilation table notes indicate 1 July 2024 for those workers’ compensation provisions). Numerous sections carry in‑text notes showing amendment by No. 21 of 2023 (eg, ss 1, 3, 5A, 8, 9, 11, 12, 13, 14, 15, 18, 19, 24, 27, 31, 32, 36, and others annotated with “No. 21 of 2023” and specific amendment section numbers).
• Major consequential amendments to other Acts were enacted contemporaneously to create the funding and damages framework:
  • Division 1 amends the Civil Liability Act 2002 by inserting s 13A (Restrictions on damages if payments received under CISS) (s 38). This aligns damages law with CISS payments and includes provisions about interim participants, gratuities and future care offsets.
  • Division 2 amends the Insurance Commission of Western Australia Act 1986 to add the Commission’s CISS function (s 40 inserting s 6(aa)) and to create the Motor Vehicle (Catastrophic Injuries) Fund in s 16(3) with composition and permitted application rules (s 41).
  • Division 3 comprehensively amends the Motor Vehicle (Third Party Insurance) Act 1943 (ss 43-54). These amendments inserted definitions, new restrictions on damages (s 3EA), declared those restrictions to be part of substantive law (s 3FA) and added s 3FB (no deduction for contributory negligence in determining damages for future care in catastrophic injury cases). They also change licensing, premium payment rules, examination procedures and transitional arrangements.
• Several provisions were inserted or replaced to align health professional examination regimes and reporting requirements (s 30 replaced; s 30A inserted for injured worker notification and insurer reporting , these are noted as No. 21 of 2023 s 676 and No. 1 of 2023 s 93 respectively within the text).
• The short title was amended (s 1 amended by No. 21 of 2023 s 663) to the present Motor Vehicle and Workplace Accidents (Catastrophic Injuries) Act 2016, reflecting the expansion to workplace accidents.

Commencement phasing:

• The compilation table documents staggered commencements: initial assent and commencement for core provisions in 2016, with subsequent amendments (Legal Profession Uniform Law Application Act, Health Services Amendment, Workers Compensation Act) commencing on dates specified in their own instruments (notably 1 July 2022, 1 July 2023, and 1 July 2024 respectively as recorded). The workplace coverage provisions of the CISS were linked to the commencement of a specific section of the Workers Compensation and Injury Management Act 2023 (s 665), so their practical effect was staged.

Scope of later amendments:

• The 2023 package of amendments substantially expanded the Act to incorporate workplace injuries, to introduce explicit reporting obligations for insurers (s 30A(4) requiring notification within seven days of liability acceptance), to insert the offences in s 31 and s 32 (false or misleading, obstruction), and to make detailed textual adjustments throughout (as evidenced by the numerous “Section X amended: No. 21 of 2023 s. Y” notes).

Taken together, the amendment history shows initial creation of a motor vehicle‑centred CISS in 2016 followed by incremental alignment with national health registration law, hospital reporting rules, and a substantial 2023 expansion to integrate workplace injuries and to finalise the insurance, licensing and damages architecture through complementary changes to the Insurance Commission Act, Civil Liability Act and the Motor Vehicle (Third Party Insurance) Act. The detailed dates and pro forma notes in the compilation table should be checked when advising on transitional or timing issues, because many operative effects are explicitly linked to commencement events in other Acts.

The statutory text provided does not record case law or judicial determinations; it contains no annotated litigation history or named decisions. Consequently, there are no reported cases embedded in the source material that interpret the CISS Act, its eligibility criteria, or the consequential amendments to the Civil Liability Act and Motor Vehicle (Third Party Insurance) Act.

Nonetheless, the Act creates several concentrated points of legal contestation where litigation or judicial interpretation is likely, grounded directly in the text. The Act itself shapes the forum and scope of judicial review for certain questions, and it introduces substantive law changes that courts will be required to apply. These are described below as statutory precincts likely to produce litigation or contested interpretation, drawing only on the operational text of the Act.

Likely legal issues and procedural routes:

• Eligibility determinations: Part 5 defines “eligibility decision” broadly (s 24) and provides internal review (s 25) and appeal routes to the District Court on specific questions , particularly whether an incident is a motor vehicle accident, and whether an injury is a motor vehicle or workplace injury to which the Act applies (s 27(2)). The District Court may be the judicial forum for disputes on those threshold facts. Other review decisions may be appealed with leave, but leave will be granted only where a question of law is involved (s 27(3)-(4)).
• Assessments of necessary and reasonable needs: The Commission must assess treatment, care and support needs according to statutory standards (s 15(2)). A participant can apply for review of an assessment (s 26). Disputes over what is “necessary and reasonable in the circumstances” or whether a particular need “relates to” the covered injury are foreseeable areas for contested expert evidence, and the regulations are empowered to define methods, criteria and medical examination requirements (s 16), which will frame judicial review questions about compliance with the regulations.
• Interaction with damages and private settlement: The Civil Liability Act insertion (s 13A) and Motor Vehicle Act insertions (ss 3EA, 3FA, 3FB) remove future care damages where CISS payments are made and, in some circumstances, preclude recovery even for needs that arose during interim participation. Litigation is likely where plaintiffs and defendants disagree about whether damages for future care should be awarded or offset because of CISS participation or because of settlement timing and whether a binding settlement in respect of future care precludes CISS participation (Civil Liability s 13A(3)-(6)). The Motor Vehicle Act’s s 3FA makes the restrictive provisions part of the substantive law, potentially generating jurisdictional questions when claims are litigated abroad.
• Negligence exceptions and interstate recovery: Section 5(3) excludes motor vehicle injuries from CISS where the owner or driver has incurred liability for negligence in respect of the injury. If the Commission later decides the Act does not apply because negligence liability exists but the motor vehicle was an interstate vehicle, s 21 permits recovery from the interstate insurer. Expectations about recovery rights and duties to notify may produce litigation over rights of recoupment and over whether negligence exceptions apply.
• Provider registration and payments: Disputes about whether services required a registered provider (s 19(2)(d)), whether registration conditions were breached (s 23(6)-(7)), or about the regulatory maximum fees under s 20 could give rise to administrative or judicial review, especially where deregistration or non‑payment follows.
• Procedural fairness and administrative law: The Act gives the Commission many discretionary powers (eg, to accept applicants, to suspend participation, to determine necessity and reasonableness, to set regulatory caps). Challenges under administrative law for procedural fairness and reasonableness are likely when participants contend that decisions were made without adequate reasons (though s 15(3) requires the Commission to notify the participant of the assessment and reasons), or without proper regulatory basis.

Judicial constraints on appeals:

• The Act narrows the appeal routes: s 27(2) only allows District Court appeals on certain specified matters; s 27(3) allows leave to appeal review decisions but the court must only grant leave where a question of law is involved (s 27(4)). This confines the scope for full rehearing in court and focuses litigation on legal errors rather than re‑examination of fact unless the facts raise a legal question.

Practical litigation considerations:

• Since many operational details are delegated to regulations, early litigation may focus on the lawfulness and reasonableness of regulations and on whether the Commission followed regulation‑mandated procedures. The Act also creates an incentive for parties to litigate threshold issues of motor vehicle accident causation, negligent liability and whether an injury is a “catastrophic injury” as prescribed, since outcomes determine access to the CISS and the availability of damages.
• The substantive law provisions in the Motor Vehicle Act (s 3FA) that make the restrictive provisions part of substantive law potentially shift settlement strategy and cross‑jurisdictional litigation dynamics because they direct treating courts to conform awards to the restrictive regime and allow recovery of any excess paid contrary to those provisions.

Because the source text contains no reported cases, parties and advisers should track subsequent judicial decisions in the District Court and higher courts for authoritative construction of the statutory terms such as “catastrophic injury”, “necessary and reasonable”, the interplay with negligence exceptions, and the validity or scope of regulatory caps and provider registration requirements.

The Act contains multiple provisions that can create practical pitfalls for claimants, providers, insurers and employers. Below are concrete “gotchas” grounded in the statutory text, each with the precise mechanism and statutory citation.

1. Damages and CISS participation interaction:
   • If a person is awarded damages, by final judgment or binding settlement, in respect of future treatment, care and support needs for the injury, the person is not eligible to be a CISS participant in respect of that injury (s 8(3)). Conversely, if a person becomes a participant, damages for future care are disallowed by amendments to the Civil Liability Act and Motor Vehicle Act (Civil Liability s 13A(5); Motor Vehicle s 3EA(4)). Gotcha: clients and advisers must plan settlements with immediate awareness that settlement on future care may close off lifetime CISS entitlements, and conversely entering CISS changes damages prospects.
2. Interim participant assumption for damages:
   • The Civil Liability Act insertion treats interim participants as if they will become lifetime participants for damages purposes (Civil Liability s 13A(6)). The Motor Vehicle Act similarly prevents recovery of damages for care that arose during interim participation (s 3EA(3)-(4)). Gotcha: plaintiffs may unknowingly lose entitlements for care that arises while they are interim participants; defendants may insist on settlement discounts or offsets on that basis.
3. Residency and suspension for workplace injuries:
   • A person cannot apply to become a participant in respect of a workplace injury unless they reside in Australia at the time of application (s 9(1A)). Participation for workplace injuries is suspended while the person is absent from Australia (s 14(1A)). Gotcha: injured workers who travel or live offshore risk losing entitlement or having payments suspended; counsel should confirm residency at time of application and manage travel plans for participants.
4. Provider registration required for payment:
   • The Commission is not required to pay for a service that is required to be provided by a registered provider if it is provided by an unregistered person at the time of provision (s 19(2)(d)). Gotcha: services delivered by otherwise capable providers but lacking Commission registration may not be paid; providers must ensure registration before delivering services intended to be billed to the CISS.
5. Regulatory caps and fees:
   • The regulations may fix maximum amounts for fees (s 20(5)-(6)) and the Act requires payments to be made consistently with regulations (s 20(7)). Gotcha: providers cannot assume Commission payment of market rates; fee schedules or prescribed persons may be used to cap payments, so fee negotiations should reference the applicable regulatory schedule.
6. Hospital reports and patient confidentiality:
   • Hospitals may disclose relevant information to the Commission and are protected from civil or criminal liability for good‑faith disclosures (s 30(2)-(3)). Gotcha: early disclosure to the Commission will happen without patient consent in some cases and cannot form the basis of a confidentiality cause of action if done in good faith; practitioners should advise clients about likely data flows.
7. Insurer reporting timelines:
   • Insurers and self‑insurers who receive a claim that appears likely to be catastrophic must provide details and medical reports and must notify the Commission within seven days after liability acceptance (s 30A(4)). Gotcha: insurers that fail to meet the seven‑day notification duty may face compliance scrutiny; employers and advisers must ensure prompt internal reporting systems.
8. No contracting out:
   • The Act applies despite anything to the contrary in a contract (s 29). Gotcha: contractual clauses attempting to exclude CISS operation, including release or waiver clauses relating to future care, cannot displace statutory entitlements; but settlements that award future care damages may still preclude CISS eligibility (s 8(3)) , counsel must be careful in drafting settlements to reflect desired outcomes.
9. Assumption of necessary and reasonable and regulatory discretion:
   • The Commission’s assessments must determine what is “necessary and reasonable” (s 15(2)), but the regulations may set methods, criteria and intervals (s 16). Gotcha: the standards for necessity and reasonableness are mediated by regulation and Commission practice; lack of precise statutory detail means outcomes may vary with administrative policy and regulators’ interpretations.
10. Recovery from interstate insurers in negligence cases:
    • If the Commission accepts a person as an interim participant and later decides the Act does not apply because negligence liability exists, the Commission may recover payments already made from the appropriate person if the motor vehicle is an interstate vehicle (s 21). Gotcha: cross‑jurisdictional claims and insurance determinations may trigger later recoupment; participants should be aware of possible clawbacks.
11. Commission not liable for legal costs for assessments:
    • The Commission is not liable for legal costs for a participant’s legal services in relation to assessments (s 17). Gotcha: participants may face out‑of‑pocket legal costs to contest assessments or eligibility, absent regulations providing otherwise; practitioners should budget and advise clients accordingly.
12. Limited appeal routes and leave requirements:
    • Appeals to the District Court are limited to certain eligibility issues without leave, while other review decisions require leave and the court will grant leave only where a question of law is involved (s 27(2)-(4)). Gotcha: factual disagreements about medical assessments may not be readily appealed to the District Court; internal review procedures and expert evidence at the administrative stage are therefore crucial.
13. Motor sports and terrorism exclusions:
    • The Act excludes motor sports event injuries and injuries resulting from terrorist acts (s 5(5)). Gotcha: participants injured in motorsport contexts are excluded; events on private land have exclusions unless specific insurance or interstate registration applies (s 5(4)).
14. Transitional and commencement timing:
    • Multiple commencement dates and transitional provisions exist (s 2; Motor Vehicle Act transitional provision s 54). Gotcha: cases occurring near commencement windows require careful attention to which version of the law applies.

Each “gotcha” above arises directly from a statutory provision. Advisers should map client facts to these provisions early in case selection, settlement negotiation, claims planning, provider on‑boarding, and insurer notification processes.

Compliance is a multi‑actor exercise: injured persons, providers, hospitals, insurers, the Commission and employers each have discrete, documentable obligations. Below is a concrete checklist of steps grounded in the statutory text to reduce risk and align behaviour with statutory duties.

For injured persons (potential participants):

1. Apply correctly and promptly:
   • Submit an application to the Commission in the manner and form the Commission determines and include all information requested (s 9(1)-(2)). For workplace injuries, confirm you reside in Australia at the time of application (s 9(1A)).
2. Cooperate with assessments:
   • Attend and comply with assessment procedures, including medical examinations by health professionals as required under the regulations (s 15(1); s 16(2)(d)). Expect to receive written notice of the assessment and reasons (s 15(3)).
3. Avoid false statements:
   • Do not provide false or misleading information in any application or communication with the Commission (s 31). Penalty is a $10,000 fine.
4. Notify the Commission where required:
   • If you are an injured worker who elects to retain damages rights or receive damages that include future treatment, care and support amounts, notify the Commission within seven days (s 30A(5)).
5. Understand implications of settlement:
   • Be aware that a final judgment or binding settlement awarding damages for future care may make you ineligible for CISS participation (s 8(3); Civil Liability Act s 13A(5)). Seek legal advice before settling future care elements.

For service providers and private hospitals:

1. Register where required:
   • If the work you do is prescribed as requiring registration to be paid by the Commission, apply for and maintain registration under s 23. Ensure you meet competency standards and comply with registration conditions (s 23(4)-(7)).
2. Verify fee schedules and regulatory caps:
   • Check whether regulations fix maximum payable amounts for services (s 20(5)-(6)). If you intend to invoice the Commission, ensure your fees conform to any published schedules or prescribed persons’ recommendations.
3. Maintain records and comply with conditions:
   • Keep documentation showing compliance with registration conditions; contravening registration conditions without a reasonable excuse attracts a $10,000 fine (s 23(6)).

For hospitals and clinicians:

1. Implement notification procedures:
   • If a patient is admitted with an injury that is or is reasonably believed to be catastrophic, ensure authorised personnel can notify and disclose relevant information to the Commission promptly (s 30(2)). Good‑faith disclosures attract immunity (s 30(3)).
2. Protect and publish policies:
   • Ensure internal confidentiality policies reflect the statutory immunity for good‑faith reporting to the Commission, and that patient consent practices are adjusted to account for the statutory disclosure route.

For insurers, WorkCover and employers:

1. Immediate reporting obligations:
   • If an insurer receives a claim that appears likely to be for a catastrophic injury, provide the Commission with claim details and copies of medical reports and notify the Commission within seven days after liability to pay compensation has been accepted or determined (s 30A(4)). Failure to do so risks regulatory issues.
2. Manage worker notifications:
   • Inform workers of their obligation to notify the Commission where they elect to keep the right to damages or where damages have been received for future care (s 30A(5)).
3. Monitor interstate vehicle exposure:
   • In cross‑jurisdictional cases, track whether a motor vehicle was an interstate vehicle covered by another State/Territory scheme; the Commission may recover payments from the interstate insurer if negligence makes the Act inapplicable (s 21).

For the Insurance Commission (administration and governance):

1. Publish forms, guidelines and register:
   • Set the application form and information requirements (s 9(2)), maintain and publish the register of registered providers (s 23(2); s 23(3)), and issue guidelines with web publication and ensure staff have regard to them (s 33(1)-(4)).
2. Develop assessment protocols and fee schedules:
   • Implement regulations (and associated Commission policy) to clarify methods and criteria for necessity and reasonableness (s 16(2)(c)), intervals for review (s 16(2)(b)), and fee schedules or maximum amounts under s 20 to guide providers and participants.
3. Financial management:
   • Operate the Motor Vehicle (Catastrophic Injuries) Fund in accordance with the Insurance Commission Act amendments, ensuring moneys are applied only to Commission functions for CISS (s 41 new s 16(3)).
4. Recovery and audit procedures:
   • Establish processes to recover payments where negligence exceptions or interstate insurance exposure arise (s 21) and to audit compliance with registration conditions and regulatory fee caps.

For legal advisers:

1. Consider interaction with damages:
   • Before negotiating or accepting settlement on future care, confirm how the settlement will affect CISS eligibility (s 8(3); Civil Liability s 13A(5)). If advising defendants, evaluate whether a plaintiff’s interim participation status affects liability or potential offsets (Civil Liability s 13A(6)).
2. Prepare for limited appeals:
   • Counsel clients that appeal routes are constrained (s 27); emphasise the importance of administrative review procedures and ensure evidence at the administrative stage is complete and robust.
3. Budget for assessment costs:
   • Advise clients that the Commission is not liable for legal costs in relation to assessments (s 17) and plan for representation costs accordingly unless regulations provide otherwise.

Practical operational steps across actors:

• Design and publish internal checklists for detection of possible catastrophic injury claims, immediate hospital reporting triggers, insurer notification workflows (seven‑day deadline), and provider registration checks.
• Catalogue and map services that are likely to be subject to registration and fee schedules, and align invoicing systems with Commission requirements.
• Ensure confidentiality and consent forms acknowledge statutorily allowed disclosures to the Commission for catastrophic injuries and that patients are given information about how their health data may be used for assessment purposes.
• Track commencement dates and transitional rules for cases occurring around the Act’s operative threshold dates (s 2 and Motor Vehicle Act transitional provision s 54).

Following these steps will align actors’ conduct to the Act’s procedural and substantive requirements and reduce exposure to the statutory fines, non‑payment risk and administrative sanctions set out in the text.
