Executive Summary: Key Legal and Evidentiary Issues

• Judicial review focused on whether the Veterans Review and Appeal Board (VRAB) reasonably denied disability benefits.

• Central issue was whether military service significantly contributed to the applicant’s kidney stones.

• Medical evidence presented was deemed vague and inconclusive regarding service-related causation.

• The VRAB applied the required liberal and veteran-friendly interpretation under section 39 of the Veterans Review and Appeal Board Act.

• Evidence of family history and unrelated medication use weighed against establishing a service connection.

• The court upheld that more than a mere possibility of causation is required to succeed under the Veterans Well-being Act.

Facts and outcome of the case

The applicant, David Mushing, is a retired Canadian Armed Forces veteran who served at Canadian Forces Base (CFB) Shearwater between 2002 and 2008. During that time, he worked in a control tower where he claims there was no access to potable drinking water. He alleges that chronic dehydration from this environment led to recurring kidney stones beginning in 2005. As a result, he sought compensation under section 45 of the Veterans Well-being Act for a service-related disability.

Veterans Affairs Canada denied the disability claim in 2015, citing insufficient evidence linking the kidney stones to military service. Mushing appealed that decision to the Entitlement Review Panel (ERP), which upheld the denial. He then brought the matter before the VRAB Entitlement Appeal Panel, which also affirmed the prior decisions.

The VRAB Panel accepted that Mushing had a valid diagnosis of kidney stones and that it was a permanent disability. However, it found no adequate medical evidence showing that the condition was caused, aggravated, or contributed to by military service. The panel considered a letter from Dr. Jung stating that chronic dehydration may have contributed to the condition but found it too vague and hypothetical. The panel also noted that other risk factors, including family history and the applicant’s use of a medication known to cause kidney stones, had not been addressed in the medical opinion.

On judicial review, the applicant argued that the VRAB failed to properly apply the evidentiary standard set out in section 39 of the VRAB Act, which requires resolving doubt in favor of the veteran. He relied on a previous case, Ouellet, to argue that even a possible connection should suffice. The respondent countered that the evidence did not establish a significant causal connection between the kidney stones and military service, and that the medical opinion lacked detail.

The court found that the VRAB correctly articulated and applied the legal principles required under the Veterans Well-being Act and the VRAB Act. It ruled that the panel’s conclusion was reasonable, particularly in light of the absence of direct medical evidence of chronic dehydration during service and the failure to account for other possible causes. The court emphasized that while the law requires a liberal interpretation in favor of veterans, it does not eliminate the need to demonstrate a significant causal link on a balance of probabilities.

The application for judicial review was dismissed. The court awarded no costs.
