1 Name This is the Statement of Principles concerning Huntington disease (Reasonable Hypothesis) (No. 49 of 2023). 2 Commencement This instrument commences on 23 May 2023. 3 Authority This instrument is made under subsection 196B(2) of the Veterans' Entitlements Act 1986. 4 Repeal The Statement of Principles concerning Huntington's chorea No. 37 of 2015 (Federal Register of Legislation No. F2014L01851) made under subsection 196B(2) of the VEA is repealed. 5 Application This instrument applies to a claim to which section 120A of the VEA or section 338 of the Military Rehabilitation and Compensation Act 2004 applies. 6 Definitions The terms defined in the Schedule 1 - Dictionary have the meaning given when used in this instrument. 7 Kind of injury, disease or death to which this Statement of Principles relates (1) This Statement of Principles is about Huntington disease and death from Huntington disease. Meaning of Huntington disease (2) For the purposes of this Statement of Principles, Huntington disease means a genetic disorder of the brain, which involves progressive degeneration of nerve cells in the basal ganglia and cortex, leading to motor, emotional and cognitive dysfunction. (3) While Huntington disease attracts ICD‑10‑AM code G10, in applying this Statement of Principles the meaning of Huntington disease is that given in subsection (2). (4) For subsection (3), a reference to an ICD-10-AM code is a reference to the code assigned to a particular kind of injury or disease in The International Statistical Classification of Diseases and Related Health Problems, Tenth Revision, Australian Modification (ICD-10-AM), Tenth Edition, effective date of 1 July 2017, copyrighted by the Independent Hospital Pricing Authority, ISBN 978-1-76007-296-4. Death from Huntington disease (5) For the purposes of this Statement of Principles, Huntington disease, in relation to a person, includes death from a terminal event or condition that was contributed to by the person's Huntington disease. Note: terminal event is defined in the Schedule 1 – Dictionary. 8 Basis for determining the factors The Repatriation Medical Authority is of the view that there is sound medical-scientific evidence that indicates that Huntington disease and death from Huntington disease can be related to relevant service rendered by veterans, members of Peacekeeping Forces, or members of the Forces under the VEA, or members under the MRCA. Note: MRCA, relevant service and VEA are defined in the Schedule 1 – Dictionary. 9 Factors that must exist At least one of the following factors must as a minimum exist before it can be said that a reasonable hypothesis has been raised connecting Huntington disease or death from Huntington disease with the circumstances of a person's relevant service: (1) inability to obtain appropriate clinical management for Huntington disease. 10 Relationship to service (1) The existence in a person of any factor referred to in section 9, must be related to the relevant service rendered by the person. (2) The factor set out in subsection 9(1) applies only to material contribution to, or aggravation of, Huntington disease where the person's Huntington disease was suffered or contracted before or during (but did not arise out of) the person's relevant service. 11 Factors referring to an injury or disease covered by another Statement of Principles In this Statement of Principles: (1) if a factor referred to in section 9 applies in relation to a person; and (2) that factor refers to an injury or disease in respect of which a Statement of Principles has been determined under subsection 196B(2) of the VEA; then the factors in that Statement of Principles apply in accordance with the terms of that Statement of Principles as in force from time to time.
