9 In my respectful opinion the approach preferred by McLure JA (which is consistent with that taken by Roberts-Smith JA) is that which should be adopted. In my opinion there may be a case in which, for some reason or another, the quantum of economic loss would take the damages, assessed in the ordinary way, over Amount A but in which, even then, the disability is not appropriately described as having been so severe as to amount to a most extreme case of a disability of less than 30 per cent in degree. Moreover, it seems to me that, if the legislature had had the intention ascribed to it by Murray AJA, it would have provided, in s 93F(1), that in a case of the kind referred to in the opening words of that section, the damages to be awarded should be those that would have been awarded at common law, subject to the maximum provided for by Amount A. Instead, it seems to me, the legislature has deliberately chosen a different formula, being one which requires that damages be awarded in accordance with the severity of the disability, subject to the maximum provided for in a most extreme case of a disability of less than 30 per cent in degree. I agree, in this last respect, with what was said by Handley JA in Dell v Dalton at 532 - 533, to the effect that the use of the indefinite article provides for the creation of a class of "most extreme" cases which necessarily means that the cases may be different, and that some may be worse than others.
