41 The worker had suffered back injuries in the course of his employment which led to various absences from work. The injuries were compensable. He had remained partially incapacitated and the employer provided light duties. The worker then decided to accept an offer by the employer to its employees generally of early retirement, with a special retirement allowance. As a result, the worker resigned and received $13,012 from the respondent, including $5279 superannuation benefits and $4446 retirement benefits. He tried to get other work but was unsuccessful and went on an invalid pension. Two and a half years after his retirement he lodged a claim for weekly payments. He notified his former employer that he was ready, willing and able to undertake whatever suitable work the employer might offer him.
42 On appeal, the Full Supreme Court held that s 67 could have no application. By his acceptance of early retirement in return for a substantial financial benefit, the worker had removed himself from the employer's workforce and had intimated that he was no longer available for work. In those circumstances, it was held that s 67 could not operate to convert the worker's partial incapacity into notional total incapacity. The court further held that the worker was estopped by his conduct from asserting that he was available for work.
43 D'Andrea is immediately distinguishable from the matter at hand by reason of the fact that it was decided under different legislation, the fact that the worker there was only partially incapacitated for work, and the fact that the worker there was, by choosing to retire and accept the benefits of the employer's early retirement scheme, found to have impliedly indicated that he was no longer available for work.
44 Later decisions applied the principle of mutuality to s 35(2) of the current Act, although as noted by King CJ in WorkCover Corporation (Plas-tec Pty Ltd) v Grigor [1994] SASC 4450; (1994) 62 SASR 283, the principle could not be applied in precisely the same way as it did under the previous legislation given that the pre-condition for the deeming of partial incapacity to be treated as total incapacity in s 35(2) did not, unlike the earlier s 67, have an aspect that was specific to the worker's employer.
45 In Grigor a partially incapacitated worker, who had been coping with modified light duties notwithstanding concerns that his compensable back disability might be aggravated, resigned in order to commence a TAFE course in hotel catering. After the worker resigned, the employer engaged another person to perform the duties the worker had done in his partially incapacitated state. For his part, the worker worked for a few months in a restaurant before that work came to an end. He sought other employment but was unable to find any.
46 The worker then wrote to the employer seeking employment within the physical limitations imposed by his disability. A week or so later he followed up his letter with a telephone call to the employer seeking suitable employment. The employer did not offer the worker any suitable work because it said there was no position available for him.
47 The Corporation rejected the worker's claim for weekly payments on the ground that he had "breached mutuality by resigning from employment which was reasonably available, suitable and for which he was certified fit to perform". By resigning, it was contended, the worker had indicated that he was not thereafter ready, willing and able to undertake the suitable work that the employer had made available to him.
48 A Review Officer set aside the Corporation's decision and determined that the worker was entitled to weekly payments. The Corporation's appeals to both the Workers Compensation Tribunal and to the Full Bench of the Supreme Court were dismissed.
