16 On its face, s 134AB(27)(b) refers to, and indeed requires, the making of specified kinds of costs orders in specified situations in common law proceedings under s 134AB "unless subsection (28) applies". However, it is difficult to understand the intended operation of s 134AB(27)(b) because, as the Act stood after that provision was introduced[23], there was apparently no proper scope for a proceeding to be commenced in the absence of a prior statutory offer or deemed statutory offer. The wording of s 134AB(27)(b)(i) ("if no liability to pay damages is established") matches exactly the corresponding wording of s 134AB(28)(a). The wording of s 134AB(27)(b)(iii) ("if damages are awarded") is fully covered by the corresponding wording of paragraphs (b), (c) and (d) of s 134AB(28). So it seems that subsection (28) would have applied, to the exclusion of ss 134AB(27)(i) and (iii), in every case to which the latter provisions would otherwise have applied.[24] Subsequently, s 135BA has been introduced whereby, on certain conditions, terminally ill workers can commence proceedings that would otherwise have been subject to s 134AB without going through the steps prescribed by the section, but that development may throw no light on the intended operation of s 134AB(27)(b)(i) and (iii). On the other hand, however, s 134AB(27)(b)(ii) may well have potential separate work to do, having regard to the thresholds set out in provisions such as s 134AB(22)(a) and (b). A case where "damages are assessed but cannot be awarded under this section" (to use the words of s 134AB(27)(b)(ii)), would not fall within paragraph (b), (c) or (d) of s 134AB(28)[25], and such a case presumably would not fall within paragraph (a) either, because such a case is treated by s 134AB(27)(b)(ii) itself as being different from a case where "no liability to pay damages is established", that being the language of both s 134AB(27)(b)(i) and of s 134AB(28)(a). So it seems that this may well be one more express exception in s 134AB itself to the suggested "rule" that s 134AB(28) is exhaustive, in addition to the apparent exceptions in subsections (29), (30) and (31). This particular exception would only operate at the stage where the outcome of the proceeding is known. However I think that, read cumulatively, these apparent exceptions are such as to "prove" (ie test, and, in this instance, demolish) the suggested "rule", even apart from the other considerations of language and policy to which I have so far referred, and even apart from the considerations of precedent to which I am about to refer.
