16 In deciding whether Mr Jarrett's report should be admitted it is necessary to emphasise the nature of Class 1 proceedings in this Court and that a commissioner with appropriate expertise will be determining the matter and will be expected to apply that expertise. I need to balance the desire of the Council to put before the Court all the experts it considers necessary with the concern for timely preparation of the matter for hearing and the need to avoid duplication of expert evidence. It is not sufficient to argue as a principal reason for relying on additional expert evidence for which no order was sought before its service, served four weeks before the hearing that there is no prejudice to the Applicant. No doubt the Applicant is a relatively well resourced developer, as is Westfield who provided the reports to the Council. These reports have not been provided in a timely fashion pursuant to the required order under the UCPR. The contentions raised by the Council which Mr Jarrett is addressing are considered in the evidence of the town planners so that there is already evidence on the issue of retail design. Excluding Mr Jarrett's evidence will not result in the issue not being considered at all. It will be the subject of expert town planning evidence. Balancing all these factors I consider Mr Jarrett's report should not be able to be relied on in the proceedings.
17 Mr Robinson's evidence is intended, as I understand it, to identify how the Council approaches decisions under its planning instruments as relevant to the issues in these proceedings. His report does so. While there may be some overlap with what the expert town planners deal with, that is not the case for the whole report. It can be admitted and relied on.
18 My conclusions and the agreement of the parties in relation to evidence suggest the order sought in the Applicant's Notice of Motion needs to be amended to take into account that the evidence of Mr Robinson can be relied upon.
Joinder application
19 As I have not allowed in all three reports provided by Westfield to the Council I need to consider Westfield's joinder motion. Westfield's counsel argues that it should be joined under s 39A(a) of the Court Act because this will enable an issue to be considered that would not be sufficiently addressed if the entity was not joined as a party and, under s 39A(b)(ii), that joinder is in the public interest because of the potential impact that the proposed development will have on numerous businesses in the Council area. The only possible issue the argument in relation to s 39A(a) can apply to is the report of Mr Jarrett which I have held above should not be read in these proceedings.
