Trustees for the Roman Catholic Church for the Diocese of Bathurst v Hine

The Trustees for the Roman Catholic Church for the Diocese of Bathurst (appellant) sought to appeal a decision of the Workers Compensation Commission (NSW) concerning a claim for permanent impairment compensation by Mr Hine (respondent). The core of the dispute revolved around whether prior consent orders, which included a finding that the respondent had "fully recovered" from psychological injury, created an issue estoppel that precluded the respondent from pursuing a subsequent claim for permanent impairment compensation. The appellant argued that these prior findings should prevent the respondent from asserting a permanent impairment and that the Commission lacked jurisdiction to determine such a dispute.

The central legal issues before the Court of Appeal were whether the consent orders made in earlier proceedings gave rise to an issue estoppel, and if so, whether that estoppel operated to prevent the respondent from pursuing his claim for permanent impairment under section 66 of the *Workers Compensation Act 1987* (NSW). This involved considering the interplay between the doctrine of issue estoppel and the statutory scheme governing the jurisdiction of the Workers Compensation Commission, particularly sections 293 and 321 of the *Workplace Injury Management and Workers Compensation Act 1998* (NSW), which deal with medical disputes and their resolution.

The Court of Appeal held that the statutory scheme for resolving medical disputes regarding permanent impairment under the *Workers Compensation Act 1987* (NSW) and the *Workplace Injury Management and Workers Compensation Act 1998* (NSW) was inconsistent with the operation of issue estoppel in the manner contended by the appellant. The Court reasoned that the statutory framework mandated a specific process for determining permanent impairment, including medical assessment, which could not be circumvented by prior consent orders. The Court found that the existence of a "medical dispute" as to permanent impairment was a matter to be determined according to the statutory process, not by reference to prior findings that might be inconsistent with the current claim.

Leave to appeal was granted, but the appeal was ultimately dismissed. The parties agreed that there would be no order as to costs.
