Topic and Military Rehabilitation and Compensation Commission (Veterans' entitlements)

This matter concerned a claim by Ms Topic for acceptance of liability for osteoarthritis of her right knee, which she asserted arose out of her service in the Army Reserve. The Military Rehabilitation and Compensation Commission (MRCC) had denied liability, and Ms Topic sought review of this decision before the Tribunal. The central dispute was whether the osteoarthritis was connected to her defence service on the balance of probabilities, as required by the relevant Statement of Principles (SoP).

The Tribunal was required to determine whether Ms Topic’s osteoarthritis of the right knee was a service injury or disease under the *Military Rehabilitation and Compensation Act 2004* (MRC Act). This involved assessing whether the material before the Tribunal raised a connection between her condition and her defence service, and whether that connection was upheld on the balance of probabilities, in accordance with the applicable SoP concerning osteoarthritis. The standard of proof for such claims, particularly in relation to peacetime service, required the Tribunal to be reasonably satisfied of the connection.

In reaching its decision, the Tribunal considered the evidence presented by both Ms Topic and the respondent. Ms Topic contended that her knee condition was a direct result of the physical stresses of her ADF service, including kneeling, squatting, and maintaining fitness. However, the respondent argued that none of the factors outlined in the relevant SoP were satisfied, and that medical evidence indicated the onset of the condition predated any specific service-related incident. The Tribunal applied the principles established in *Briginshaw v Briginshaw* regarding the standard of reasonable satisfaction, noting that such satisfaction should not be based on inexact proofs or indefinite testimony.

Ultimately, the Tribunal was not satisfied, on the balance of probabilities, that Ms Topic’s osteoarthritis of the right knee was connected with her defence service. Consequently, the Tribunal affirmed the decision under review.
