87 On the face of it, the evidence, to which we have just referred, was compelling as to the degree to which the applicant's lumbar spine injury impaired his capacity to work. While the judge set out a substantial part of that evidence earlier in her reasons, her Honour did not explain why, in the face of that evidence, she reached the conclusion that the consequences of the applicant's lumbar impairment, in respect of his earning capacity, were not serious, as defined in s 134AB of the Act. The evidence, to which we have referred, squarely raised that issue for determination. On its face, the finding by the judge, that the applicant retained the capacity to perform the tasks that he was carrying out before his employment was terminated (which we shall discuss further), was not, of itself, a sufficient explanation as to why the judge concluded that the loss of earning capacity consequences to the applicant were not serious, in the face of the applicant's evidence as to the pain and difficulty that he had experienced in performing that light work, and in the face of the medical evidence to which we have referred. Notwithstanding that, ultimately, the determination by the judge, of that issue, was a matter of evaluation, we do not consider that her Honour gave sufficient reasons for the conclusion that those consequences were not serious.
