The Appellant's Submissions
11 The appellant pointed to the evidence that prior to about May 1990 the respondent was an employed electrician, and that thereafter he conducted his own electrical contracting business. He did this, initially, in his own name and then in partnership with his wife and, for a time, engaged as many as twelve electricians in the business. The submission was that he gave unchallenged evidence that in addition to the performance of some manual work as an electrician, he carried out the vast bulk of the managerial duties of the business including doing all paper work; giving quotations; seeking to win business; purchasing materials; invoicing; banking; and engaging sub-contractors.
12 It was submitted that when the respondent suffered the injury on 1 February 1994, the business was carried on by him and his son and, notwithstanding the injury, continued to trade and, by about November 1994, a further two electricians had been engaged. His Honour found that there did not seem to be any doubt, on the evidence, that from 1 February 1994 to the date of the respondent's retirement, his duties in the business were restricted to driving his son to work sites, writing out bills, inspecting the work performed, certifying it, ordering in materials and paying for them.
13 It was submitted that the proper approach to the issue of the extent of disablement would have been to consider the evidence and make findings as to all the respondent's normal duties in carrying out his business as an electrical contractor prior to the injury, and then to consider the extent to which he had, solely as a result of his injury, become unable to engage in that occupation. It was submitted that his Honour failed to do this, but merely made findings concerning some aspects of the business, and that he ought to have found that prior to his injury the respondent's normal duties in carrying out his business included the administrative tasks to which the submissions earlier made reference.
14 His Honour did find that before the injury the respondent carried out physical work as an electrician, but that after it he was restricted to the duties to which I have referred and "supporting his son so that his son could make a living as a working electrician". He was of the view that "the core function" of the respondent was the performance of work which generated income.
15 The submissions continued that his Honour made findings concerning the duties that the respondent in fact carried out in the business following his injury, but that no findings were made as to the extent to which he, solely as a result of his injury, had become unable to carry out all his normal duties; and that there was no evidence upon which he could have concluded that the respondent had become unable to carry out any of the administrative duties to which the submission referred. This approach, in my opinion, would have led to his Honour posing the incorrect question. The correct question, allowing for the concession of "Partial Disablement", was whether he had become unable to engage in his usual occupation on either a full-time or a part-time basis. It was the respondent and not the business, which was insured, and his Honour was correct in focussing attention on the respondent's capacity, rather than the continuance of the business.
16 It was submitted that the trial Judge's approach to the construction of the definition of "Total Disablement" was erroneous in that he failed to have due regard to the language of the policy and, in particular, to accommodate the words of the two definitions. Rather, it was submitted, his Honour followed an approach "substantially based upon the notion that the respondent as the owner of an electrical contractor's business, ought not to be disadvantaged in comparison with a notionally insured employed electrician", and that there was no justification for that approach in the language of the policy. The consequence of the submission, linked with the further submission based on the disparity in the amount paid for "Total Disablement" and "Partial Disablement", led to the submission that the policy should be construed so that "Total Disablement" only occurs if there is a level of disability greater than that necessary to satisfy "Partial Disablement".
17 I think the last submission is correct, because the definition of "Total Disablement" involves an inability to engage in one's usual occupation whether on a full or part-time basis. However, I do not agree that the analogy to an employed electrician led his Honour into error. All he was pointing out was that the respondent could only engage in part of his usual occupation, and that that was not the part which generated income.
18 The submissions then turned to the question of "Partial Disablement" and stated that "substantial" meant "considerable" as opposed to "real or of substance".
19 Mr Darke submitted:-
"The requisite inability for the purposes of the Total Disablement definition is an inability to engage in the usual occupation at any sensible or realistic level, even if there is an ability to perform some of the normal duties of that occupation.
