Gregory and Comcare (Compensation)

This matter concerned an appeal by Gregory against a decision by Comcare regarding compensation for a previously accepted injury. The dispute centred on whether the effects of a compensable injury, specifically a disc prolapse sustained on 21 January 1993, continued to be a material contributing factor to the applicant's current lumbar spine condition, incapacity, and entitlement to medical expenses and incapacity payments. The decision was made by Ms S Taglieri SC, Member, of the Tribunal.

The primary legal issue before the Tribunal was to determine whether the applicant's ongoing lumbar spine condition and resulting incapacity were causally linked to the original injury sustained in 1993, or if intervening factors such as new injuries or the natural progression of degenerative changes had broken the chain of causation. The Tribunal was required to assess the evidence, particularly expert medical opinions, to ascertain if the prolapsed disc remained a relevant and material contributor to the applicant's current symptoms and inability to perform heavy work.

The Tribunal preferred the evidence of Dr Muthu and Mr Kossmann over that of Dr Drewry. It found that while degenerative changes in the applicant's lumbar spine by 2016 had multiple contributing factors, the disc prolapse in 1993 was a significant event that accelerated the degenerative process. Dr Muthu accepted that the prolapsed disc would never totally heal and that the 1993 injury probably accelerated degeneration, even though the applicant's subsequent work as a baggage handler also likely contributed. The Tribunal concluded that the 1993 injury constituted an injury within the meaning of the Act and remained a relevant and material contributing factor to the applicant's ongoing condition and incapacity. The Tribunal was not persuaded by Comcare's argument that new injuries or a separate degenerative condition had broken the chain of causation, finding little compelling evidence to support this. The Tribunal considered the applicant's intermittent symptoms and incapacity to be consistent with the progressive degenerative changes, which were themselves partly a result of the original prolapsed disc.

The Tribunal set aside the decision under review and remitted the matter for redetermination.
