Knox v Accident Rehabilitation and Compensation Insurance Corporation

Knox v Accident Rehabilitation and Compensation Insurance Corporation

The work tasks identified could cause or contribute to extensor tenosynovitis (s7(1)(a)) and non‑work activities did not materially account for it (s7(1)(b)), but the appellant failed to prove s7(1)(c): on balance the risk of developing the condition was not shown to be significantly greater for persons performing the employment task than for those who do not, the Court preferring Dr Monigatti's analysis and epidemiology; therefore no entitlement to cover and the appeal is dismissed.
