[29] There are a number of oddities about that specific order, of which one is that Mr Gillam's evidence did not in terms describe any reasonable excuse for delay in providing a notice to Alldrill. His evidence asserted Watpac was responsible. It was the reports obtained by Watpac received by his solicitors, together with Mr Gillam's strong opinions disclosed in his own evidence and documents, which provided the material capable of being a reasonable excuse. Next, that declaration of a reasonable excuse provided by Mr Gillam's oral evidence was not actually an order for which Mr Gillam had applied, although his counsel at the hearing below did make what was described as a "s 18 application" toward the end of argument.[17] Since s 18 does not require a court to declare or find whether a reasonable excuse exists or not, and since the drafting of s 18(1)(c)(ii) actually assumes, if anything, the absence of a reasonable excuse for delay where delay is the non-compliance, there appears no need to make an order as to the existence of a reasonable excuse. Where there has been delay, and where at the time an application under s 18 is heard a reasonable excuse for that delay exists, then whether that excuse has been provided as required by s 9(5) or not, its existence will be relevant to the exercise of the s 18(1)(c)(ii) discretion in a claimant's favour; but demonstrating that one exists is not mandated by the section.
