Williams and Repatriation Commission (Veterans' entitlements)

This case concerned an appeal by Mr Williams against a decision of the Repatriation Commission that his Post-Traumatic Stress Disorder (PTSD) was not war-caused. The Administrative Appeals Tribunal had affirmed the Commission's decision. The matter came before Deputy President Constance of the Administrative Appeals Tribunal.

The primary legal issue before the Tribunal was whether Mr Williams' PTSD resulted from an occurrence that happened while he was rendering operational service, as defined by section 9 of the *Veterans' Entitlements Act 1986* (Cth). This required the Tribunal to consider the standard of proof stipulated in section 120 of the Act, which mandates that the Commission must be satisfied beyond reasonable doubt that there is no sufficient ground for determining an injury or disease to be war-caused. Furthermore, the Tribunal had to assess whether a hypothesis connecting the PTSD to the circumstances of Mr Williams' service was reasonable, as defined by section 120A of the Act, which requires reference to a Statement of Principles.

The Tribunal accepted Mr Williams' evidence regarding the harassment and physical assaults he endured from colleagues, Mr Toner and Mr Frost, both before and during his deployment to East Timor. It also accepted the opinion of Dr Dinnen, a psychiatrist, regarding Mr Williams' diagnosis of PTSD and its onset date. Applying section 120 of the Act, the Tribunal found that it could not be satisfied beyond reasonable doubt that Mr Williams' PTSD was not war-caused, given the material before it and the accepted evidence. The Tribunal noted that it was not required to apply the definition in the Statement of Principles to determine the existence or description of the condition itself.

Consequently, the Tribunal set aside the reviewable decision of the Repatriation Commission and substituted a decision that Mr Williams' PTSD, with a clinical onset of 21 January 2002, was war-caused within the meaning of the *Veterans' Entitlements Act 1986* (Cth).
