Evans and Repatriation Commission (Veterans' entitlements)

This matter concerned an application for a war widow's pension following the death of Mr. Rogers, who served as a medical assistant in South Vietnam during the Vietnam War. The applicant sought to establish that Mr. Rogers' death, primarily from aspiration pneumonia with dementia with Lewy bodies as a contributory cause, was "war-caused." The case came before the Tribunal for review of a previous decision.

The central legal issues before the Tribunal were whether Mr. Rogers suffered from major depressive disorder or post-traumatic stress disorder (PTSD) at least 10 years prior to the clinical onset of his neurocognitive disorder with Lewy bodies dementia, and if so, whether specific stressors or environmental conditions during his service were met. These questions were framed within the context of the relevant Statements of Principles (SoPs) governing claims for neurocognitive disorder with Lewy bodies and PTSD.

The Tribunal applied the "Deledio steps" to assess whether the material before it pointed to a reasonable hypothesis connecting Mr. Rogers' death to his war service. While acknowledging the traumatic nature of service as a medic in Vietnam, the Tribunal found that the medical evidence did not establish that Mr. Rogers suffered from major depressive disorder or PTSD at least 10 years before the clinical onset of his Lewy bodies dementia. Consequently, the hypothesis connecting his death to his war service did not fit within the applicable SoPs, rendering it not reasonable.

As the hypothesis was deemed not reasonable, the Tribunal affirmed the reviewable decision, meaning the claim for a war widow's pension was not successful on the grounds that Mr. Rogers' death was war-caused.
