Dywidag Systems International Pty Ltd v Melksham

In the case of Dywidag Systems International Pty Ltd v Melksham, the Court reviewed a decision made by an arbitrator under the Workers Compensation Act 1987. The dispute centred on the injuries suffered by the respondent, Melksham, in relation to his employment with Dywidag Systems International Pty Ltd. The arbitrator had determined that Melksham had sustained injuries to his knees, both on a specific date and over a period of time, but the employer contested these findings. The case was heard in the Industrial Division of the Supreme Court of New South Wales.

The central legal issue was whether the arbitrator was required to determine the pathology arising from an injurious event, a question that was considered in light of the precedent set by Jaffarie v Quality Castings Pty Ltd. The court needed to decide if the arbitrator's role extended to identifying the specific pathology of the injuries, or if it was sufficient for the arbitrator to conclude that an injury occurred based on the evidence presented.

The court found that the arbitrator had not sufficiently identified the pathology of the injuries, particularly those to the left knee, and therefore did not properly address the nature and extent of the injuries. The court held that the arbitrator's role included determining the specific nature of the injuries, and not merely acknowledging that an injury occurred. Consequently, the findings regarding the left knee injuries were revoked and the matter was remitted to a different arbitrator for further determination. The court also stayed the orders regarding the referral to Approved Medical Specialists pending the outcome of the re-determination of the left knee injuries.

The court's orders confirmed the finding that Melksham had suffered an aggravation or acceleration of a disease in his right knee due to his employment. However, the findings related to the left knee were annulled, and the issues were remitted to a new arbitrator. The orders regarding the referral for assessment of other conditions were stayed until the left knee injuries were re-determined.
