48 In order to understand why this issue dominated the trial, it is necessary to go into the facts a little further. During the course of the appellant's employment as a motor mechanic, he had sustained a low back injury on 22 December 1992. This injury incapacitated him to some extent, at least to the extent that he needed extra assistance to carry out his work. According to the appellant, this did not suit his employer, resulting in him being dismissed from his employment in about April 1993. It appears that he made no claim for workers' compensation, although there are some workers' compensation documents amongst the exhibits. Perhaps a claim was made but not pursued. At all events, the appellant started on a sickness allowance under the Social Security Act 1991 (Cth) in May 1993, shortly after his dismissal, and he remained on a sickness allowance for some time (until May of the following year, I think) and progressed to a disability pension for a while and, finally, he went on to unemployment benefits in the form of a job search allowance. There is evidence that he did, in fact, actively seek employment, always informing his prospective employers of his back condition. His bad back was not the only physical impairment from which he suffered at the time of the accident. The trial Judge found, and there was evidence to support the finding, that the appellant had chronic occupational dermatitis of the hands, for which he was receiving medical treatment by his general medical practitioner and for which he had been seen by at least one specialist. There is evidence that this was a serious and incapacitating condition, at least at times. He also suffered from epicondylitis, or "tennis elbow", in both elbows, which affected his capacity to use some items of mechanical equipment; and he had a troublesome duodenal ulcer.
