ZHVP and Repatriation Commission (Veterans' entitlements)

This matter concerned an application by ZHVP (the Applicant) for a disability pension, specifically claiming that Post-Traumatic Stress Disorder (PTSD) and ischaemic heart disease were defence-caused. The Repatriation Commission had previously decided that these conditions were not defence-caused. The decision was reviewed by C. J. Furnell SM.

The primary legal issues before the court were whether the applicable Statement of Principles for PTSD was the one in force at the time of the original decision or a later amendment, and whether the Applicant's PTSD was defence-caused under the relevant Statement of Principles. The court also implicitly considered the definition of "disease" and "clinical onset" in the context of the *Veterans' Entitlements Act 1986* (Cth).

The court determined that Statement of Principles 83 of 2014, which was in effect when the Repatriation Commission made its original decision in 2017, was the applicable instrument. This was based on the principle that legislative amendments generally do not have retrospective effect on accrued rights, and the High Court's decision in *Frugtniet v ASIC* regarding the role of review tribunals. The court found that the definition of PTSD in Statement of Principles 83 of 2014 was consistent with DSM-V. Crucially, the court accepted the Applicant's submission that he experienced a category 1A stressor, defined as a serious physical attack or assault, before the clinical onset of his PTSD. The court noted that the clinical onset of a disease occurs when symptoms are present that enable a doctor to identify the disease, and there was no evidence of PTSD symptoms prior to the Applicant experiencing the assault in 1976.

The court's reasoning focused on the application of the relevant Statement of Principles and the factual circumstances surrounding the Applicant's experience of a stressor and the onset of his PTSD. The court did not make specific orders in the provided text, but the analysis indicates a finding that the PTSD was defence-caused.
