EXPLANATORY STATEMENT

STATEMENT OF PRINCIPLES CONCERNING

THROMBOANGIITIS OBLITERANS

(REASONABLE HYPOTHESIS) (NO. 45 OF 2026)

VETERANS' ENTITLEMENTS ACT 1986

MILITARY REHABILITATION AND COMPENSATION ACT 2004

1.              This is the Explanatory Statement to the Statement of Principles concerning thromboangiitis obliterans (Reasonable Hypothesis) (No. 45 of 2026).

Background

1.              The Repatriation Medical Authority (the Authority), under subsection 196B(8) of the Veterans' Entitlements Act 1986 (the VEA), repeals Instrument No. 28 of 2017 (Federal Register of Legislation No. F2017L00462) determined under subsection 196B(2) of the VEA concerning thromboangiitis obliterans.
2.              The Authority is of the view that there is sound medical-scientific evidence that indicates that thromboangiitis obliterans and death from thromboangiitis obliterans can be related to particular kinds of service.  The Authority has therefore determined pursuant to subsection 196B(2) of the VEA a Statement of Principles concerning thromboangiitis obliterans (Reasonable Hypothesis) (No. 45 of 2026). This Instrument will in effect replace the repealed Statement of Principles.

Purpose and Operation

1.              The Statement of Principles will be applied in determining claims under the VEA and the Military Rehabilitation and Compensation Act 2004 (the MRCA).
2.              The Statement of Principles sets out the factors that must as a minimum exist, and which of those factors must be related to the following kinds of service rendered by a person:

 operational service under the VEA;

 peacekeeping service under the VEA;

 hazardous service under the VEA;

 British nuclear test defence service under the VEA;

 warlike service under the MRCA;

 non-warlike service under the MRCA,

before it can be said that a reasonable hypothesis has been raised connecting thromboangiitis obliterans or death from thromboangiitis obliterans, with the circumstances of that service.  The Statement of Principles has been determined for the purposes of both the VEA and the MRCA.

1.              This Instrument results from an investigation notified by the Authority in the Government Notices Gazette of 28 April 2025 concerning thromboangiitis obliterans in accordance with section 196G of the VEA. The investigation involved an examination of the sound medical-scientific evidence now available to the Authority, including the sound medical-scientific evidence it has previously considered.
2.              The contents of this Instrument are in similar terms as the repealed Instrument.  Comparing this Instrument and the repealed Instrument, the differences include:

• specifying a day of commencement for the Instrument in section 2;
• revising the Note in subsection 9(1) concerning one pack-year;

• revising the factor in subsection 9(4) concerning smoking at least one quarter a pack-year of cigarettes within the one year before clinical worsening;
• revising the factor in subsection 9(5) concerning the use of smokeless tobacco on more days than not, for at least 3 months within one year before clinical worsening;
• revising the factor in subsection 9(7) concerning inability to obtain appropriate clinical management;

• new factor in subsection 9(3) concerning use of nicotine replacement therapy on more days than not, for at least 3 years within the 6 years before clinical onset;
• new factor in subsection 9(6) concerning the use of nicotine replacement therapy on more days than not, for at least 3 months within the 2 years before clinical worsening;
• deleting factor concerning being exposed to second-hand smoke for at least 3 000 hours within the six years before the clinical onset;
• deleting factor concerning being exposed to second-hand smoke for at least 500 hours within the six years before the clinical worsening;
• new definition of ‘one pack-year’ in Schedule 1 – Dictionary; and
• deleting the definitions of ‘being exposed to second-hand smoke’ and ‘pack-year of cigarettes, or the equivalent thereof in other tobacco products’.

Consultation

1.              Prior to determining this Instrument, the Authority advertised its intention to undertake an investigation in relation to thromboangiitis obliterans in the Government Notices Gazette of 28 April 2025, and circulated a copy of the notice of intention to investigate to a wide range of organisations representing veterans, service personnel and their dependants.  The Authority invited submissions from the Repatriation Commission, the Military Rehabilitation and Compensation Commission, organisations and persons referred to in section 196E of the VEA, and any person having expertise in the field. No submissions were received for consideration by the Authority in relation to the investigation.
2.          On 12 December 2025 the Authority wrote to organisations representing veterans, service personnel and their dependants regarding the proposed Instrument and the medical-scientific material considered by the Authority.  This letter emphasised the deletion of factors relating being exposed to second-hand smoke for at least 500 hours and 3000 hours respectively. The Authority provided an opportunity to the organisations to make representations in relation to the proposed Instrument prior to its determination.  No submissions were received for consideration by the Authority. An update was made to the note in subsection 9(4) to the proposed Instrument following this consultation process

Statement of Compatibility with Human Rights

(Prepared in accordance with Part 3 of the Human Rights (Parliamentary Scrutiny) Act 2011)

Instrument No.:   Statement of Principles No. 45 of 2026

Kind of Injury, Disease or Death: Thromboangiitis obliterans

This Legislative Instrument is compatible with the human rights and freedoms recognised or declared in the international instruments listed in section 3 of the Human Rights (Parliamentary Scrutiny) Act 2011.

Overview of the Legislative Instrument

1. This Legislative Instrument is determined pursuant to subsection 196B(2) of the Veterans' Entitlements Act 1986 (the VEA) for the purposes of the VEA and the Military Rehabilitation and Compensation Act 2004 (the MRCA).  Part XIA of the VEA requires the determination of these instruments outlining the factors connecting particular kinds of injury, disease or death with service such being determined solely on the available sound medical-scientific evidence.

2. This Legislative Instrument:-

• facilitates claimants in making, and the Repatriation Commission and the Military Rehabilitation and Compensation Commission in assessing, claims under the VEA and the MRCA respectively, by specifying the circumstances in which medical treatment and compensation can be extended to eligible persons who have thromboangiitis obliterans;
• facilitates the review of such decisions by the Veterans' Review Board and the Administrative Appeals Tribunal;
• outlines the factors which the current sound medical-scientific evidence indicates must as a minimum exist, before it can be said that a reasonable hypothesis has been raised, connecting thromboangiitis obliterans with the circumstances of eligible service rendered by a person, as set out in clause 5 of the Explanatory Statement;
• replaces Instrument No. 28 of 2017; and
• reflects developments in the available sound medical-scientific evidence concerning thromboangiitis obliterans which have occurred since that earlier instrument was determined. 

3. The Instrument is assessed as being a technical instrument which improves the medico-scientific quality of outcomes under the VEA and the MRCA. 

Human Rights Implications

4. This Legislative Instrument does not derogate from any human rights. It promotes the human rights of veterans, current and former Defence Force members as well as other persons such as their dependents, including:

• the right to social security (Art 9, International Covenant on Economic, Social and Cultural Rights; Art 26, Convention on the Rights of the Child and Art 28, Convention on the Rights of Persons with Disabilities) by helping to ensure that the qualifying conditions for the benefit are 'reasonable, proportionate and transparent'[1];
• the right to an adequate standard of living (Art 11, ICESCR; Art 27, CRC and Art 28, CRPD) by facilitating the assessment and determination of social security benefits;
• the right to the enjoyment of the highest attainable standard of physical and mental health (Art 12, ICESCR and Art 25, CRPD), by facilitating the assessment and determination of compensation and benefits in relation to the treatment and rehabilitation of veterans and Defence Force members;
• the rights of persons with disabilities by facilitating the determination of claims relating to treatment and rehabilitation (Art 26, CRPD); and
• ensuring that those rights "will be exercised without discrimination of any kind as to race, colour, sex, language, religion, political or other opinion, national or social origin, property, birth or other status" (Art 2, ICESCR).

Conclusion

This Legislative Instrument is compatible with human rights as it does not derogate from and promotes a number of human rights.
