Higgerson and Prosegur Australia Pty Ltd (Compensation)

This matter concerned a claim for workers' compensation brought by Mr. Higgerson against Prosegur Australia Pty Ltd. The dispute centred on whether Mr. Higgerson was entitled to compensation under sections 12 or 16 of the relevant legislation in relation to an incident that occurred on 16 October 2019, which involved him slipping and jarring his left knee. The proceedings were heard by Emeritus Professor P A Fairall, Senior Member.

The court was required to determine several key legal issues. These included whether Mr. Higgerson suffered from an ailment, whether he suffered from an aggravation of a prior injury, and whether he was entitled to compensation under the relevant sections of the legislation. A significant aspect of the case involved the assessment of conflicting medical evidence provided by three specialists regarding the presence of an injury on 16 October 2019 and its relationship to Mr. Higgerson's pre-existing osteoarthritis.

The court's reasoning was informed by the medical evidence, which indicated a lack of evidence for a new physical injury on 16 October 2019, with some specialists noting the absence of any injury. However, the court found that while Mr. Higgerson's employment with Prosegur Australia Pty Ltd was not a significant contributor to the development of his osteoarthritis, and the incident did not accelerate its deterioration, the fall on 16 October 2019 did aggravate his original 2002 physical injury, making it worse. The court applied the principle that an aggravation of a pre-existing injury can constitute a compensable injury.

Ultimately, the court was satisfied that Mr. Higgerson suffered an aggravation of his original 2002 physical injury due to the incident on 16 October 2019, which made that injury worse. This finding was based on a consideration of medical notes, the subsequent course of his employment, his experience of debilitating knee pain, and the expert opinions presented.
