15 The relevant costs principles identified in the cases relied on by the parties are generally in agreement, with each party emphasising that dicta which particularly supports its arguments. I particularly note [7] -[14] of GPT as a useful summary of the relevant principles and cases where there are multiple issues and the successful litigant fails on some issues. While the original points of claim raised a number of grounds of challenge, by the hearing there was only one substantive ground supported by two different arguments. In other words, I would not characterise the proceedings at hearing as raising multiple issues such as occurred in Farah and GPT and gave rise to the apportionment of costs according to the outcome of the multiple issues in those cases. The principle quoted in Waters v PC Henderson (Australia) Pty Ltd (NSWCA, 6 July 1994, unreported) per Mahoney J, as cited by Biscoe J in GPT at [10], is more apposite in the circumstances of this case. In Waters Mahoney J approved of the statement in Ritchie's Supreme Court Procedure that:
Where the proceedings involve multiple issues the application of the rule that costs follow the event may involve hardship where a party succeeds on some issues yet fails on others. Particularly is this so where, for example, a defendant succeeds on issues that occupy the bulk of time taken by the proceedings. Nevertheless, unless a particular issue or group of issues is particularly dominant or separable, it would ordinarily be appropriate to award the costs of the proceedings to the successful party without attempting to differentiate between those particular issues on which it was successful and those on which it failed.
Further, Talbot J stated in Farah at [15] that:
I agree that there is reluctance on the part of courts to make an arithmetic or mathematical assessment on an issue by issue basis and that it is generally preferable to adopt a broad brush approach to making costs orders, when necessary, on a proportional basis.
16 In terms of the hearing, there were two substantive issues raised in relation to the one remaining ground of challenge and the Applicant was successful only in relation to one of those issues. I consider there was overlap between the two issues however and that a number of the issues I had to consider in relation to the first issue (Applicant unsuccessful) were also relevant to the second issue (Applicant successful). I do not consider in these circumstances that apportionment of costs is appropriate as between the two issues so that the Applicant would receive 50 per cent of his costs, as the Respondents argued. I agree with the Applicant's counsel that the hearing dealt with the issues efficiently in two days.
17 The failure to obtain a consequential order does not disentitle the Applicant to costs. That was not a result of any failure on the Applicant's part such as the premature commencement of proceedings. The Applicant obtained a declaration about a significant matter in the case. The commencement of proceedings was not automatically negated by Centennial producing the response document required by the Director-General after the public exhibition period for the EIS had been completed. I gave three reasons at [150] as to why I refused to make the further declarations and orders sought. One of those was that I considered the response document was sufficiently within the public domain due to arrangements made in relation to it by the Second Respondent not to warrant the EIS being re-exhibited. The Applicant should have all his costs of the hearing.
