Ric Developments Pty Ltd (t/as Lane Cove Poolmart) v Muir

This matter concerned an appeal to the Court of Appeal from a decision of the Workers Compensation Commission. The appellant, Ric Developments Pty Ltd (trading as Lane Cove Poolmart), was the former employer of the respondent, Mr Muir. Mr Muir suffered an injury to his right arm while employed by Lane Cove Poolmart, resulting in a 15% permanent loss of efficient use of that arm. Following the injury and termination of his employment, Mr Muir obtained part-time work. His employer's insurer initially paid him weekly compensation to cover the difference between his pre- and post-injury wages. However, the insurer later reduced these payments to nil, based on vocational capacity tests suggesting Mr Muir's ability to earn in alternative employment exceeded his pre-injury wage. Mr Muir then claimed weekly payments for partial incapacity under section 40 of the *Workers Compensation Act 1987* (NSW).

The primary legal issues before the Court of Appeal were whether the Workers Compensation Commission, constituted by a Presidential member, had erred in law when it overturned an arbitrator's decision and awarded Mr Muir weekly payments under section 40 of the *Workers Compensation Act 1987*. Specifically, the court had to consider the proper test for determining an injured worker's diminished earning capacity, the relevance of vocational capacity tests, and the practical realities of an injured worker obtaining and retaining employment in the available labour market, as contemplated by sections 40 and 43A of the Act. The court also considered the nature of an appeal to the Commission under section 352(2) of the *Workplace Injury Management and Workers Compensation Act 1998* (NSW) and the scope of the Presidential member's powers to revoke an arbitrator's decision.

The Court of Appeal reasoned that the arbitrator had erred by failing to adequately consider the practical realities of Mr Muir's ability to obtain and retain employment in the labour market as it was actually available to him. The court emphasised that the mere results of vocational capacity tests were insufficient to determine earning capacity; rather, the assessment must reflect the actual availability of suitable employment and the worker's capacity to secure and maintain it. The Presidential member's decision to substitute a new decision was therefore justified. The court also clarified that an entitlement to lump sum compensation under section 66 of the *Workers Compensation Act 1987* does not automatically give rise to an entitlement to weekly payments under section 40.

The appeal was dismissed, and the appellant was ordered to pay the costs of the respondent.
