Evidence as to estimated costs
54 The parties have filed lengthy affidavits, submissions and supporting material. The materials relied upon by the applicants include:
(a) the affidavit of Ms Dellavedova (solicitor with principal carriage of the matter) sworn on 4 April 2014; and
(b) the report of Ms Elizabeth Harris (an accredited costs law specialist and director of Harris Cost Lawyers Pty Ltd, an incorporated legal practitioner), dated 4 April 2014.
55 The materials relied upon by the Air New Zealand Parties include:
(a) the affidavits of Ms Michelle Carr (solicitor with principal carriage of the matter) sworn on 25 March 2014 ('First Carr Affidavit') and 9 April 2014;
(b) the reports of Mr Roland Matters (a legal practitioner, legal costs consultant and director of Fairshare Pty Limited, a provider of legal cost consulting services), dated 26 March 2014 and 9 April 2014; and
(c) the report of Ms Deborah Vine-Hall (a legal practitioner, legal cost consultant and director of DSA Legal Cost Consultants Pty Limited), dated 25 March 2014.
56 The evidence shows that the Air New Zealand Parties incurred legal costs from 1 February 2007 to 20 February 2014 (billed and unbilled) of $5,822,397.85, comprising professional fees of $5,285,919.34 and disbursements of $536,478.51. These figures are not materially different to the figures advised to the applicants in the Air New Zealand Parties' bill of costs in non-taxable form. Exhibited to the First Carr Affidavit was a schedule of costs and disbursements prepared by Corrs Chambers Westgarth Lawyers ('Corrs') for the purposes of the costs determination. The Corrs costs schedule provides a breakdown of the Air New Zealand Parties' billed and unbilled fees and disbursements for the period from 1 February 2007 to 20 February 2014. The breakdown shows the rank, name and date of admission (if applicable) for each person involved in the matter and their applicable hourly rates and time spent. The schedule gives a breakdown of disbursements by category.
57 I interpolate to note that the test for allowance of costs as between parties on taxation has changed under the Rules. Costs incurred prior to 1 August 2011 are to be allowed in accordance with the rates set out in Sch 2 to the Former Rules (see r 40.29(a)), whilst those incurred on or after 1 August 2011 are to be allowed in accordance with Sch 3 to the Rules: see r 40.29(b).
58 Over the period covered by the claim, the scales of costs were amended on a number of occasions. The costs claimed have been divided into eight separate time periods which largely equate to the changes in the scale rates. They are as follows:
Period 1 1 February 2007 - 31 December 2008
Period 2 1 January 2009 - 3 January 2010
Period 3 4 January 2010 - 31 December 2010
Period 4 1 January 2011 - 31 July 2011
Period 5 1 August 2011 - 8 May 2013
Period 6 9 May 2013 - 31 October 2013
Period 7 1 November 2013 - 31 December 2013
Period 8 1 January 2014 - 20 February 2014
As can be seen, four of these periods arise for consideration under Sch 2, and the remaining four periods under Sch 3.
59 Each of the cost experts (Ms Harris, Mr Matter and Ms Vine-Hall) has provided an opinion as to the amount they consider the Court would determine to be payable pursuant to a lump sum costs order under r 40.02(b).
60 Mr Matters gave his opinion that the amount that would be payable as a lump sum was $3,693,105.64, comprising $3,288,870.00 in professional fees and $404,235.64 in disbursements.
61 Ms Vine-Hall's opinion was that the amount that would be payable as a lump sum was between $3,323,976.49 and $3,903,485.63, comprising between $2,787,497.98 and $3,367,007.12 in professional fees and $536,478.51 in disbursements.
62 Ms Harris concluded that the amount that would be payable as a lump sum was $2,091,077.61, comprising $1,761,075.64 in professional fees and $330,001.97 in disbursements.
63 The Air New Zealand Parties' estimate of $3,858,917.14 represents 66.3% of their total costs incurred ($5,846,844.15). That falls within the range provided by Ms Vine-Hall (57-67%) and compares favourably with the estimate of Mr Matters (63.4%) and the amount allowed in Seven Network (63%). It differs from the estimate of Ms Harris, which represents approximately 36%.
64 The Air New Zealand Parties argued that their estimate was well within the appropriate range, taking into account the particular circumstances of the case, and that the Court should accordingly determine that the amount that would be payable pursuant to a lump sum costs order to be (or to be around) their estimate of $3,858,917.14.
65 They submitted that the number of documents discovered by the Air New Zealand Parties and other respondents and produced by the Australian Competition and Consumer Commission was vastly greater than that assumed by Ms Harris, and each needed to be read and analysed.
66 However, in my view all three cost experts have provided evident and intelligible justification for their views by reference to the court rules, the costs scales and the principles to be applied to the application. In any event, it is important to note that whilst expert reports are useful they are not determinative.
67 The applicants submitted that the various affidavits filed by the Air New Zealand Parties did not sufficiently identify the work performed nor generally justify the costs sought, and because the costs sought are not logical, fair or reasonable, the Court should decline to name a lump sum as appropriate. They argued that if that submission fails, then to the extent that it is possible to determine that any order ought to be made, it should be limited to amounts that fairly represent costs that had been demonstrably incurred in this proceeding and were necessary and proper for its conduct.
68 Doing the best they can, the applicants contended that, based on the material which Air New Zealand has chosen to put before the Court, the amount that fairly represents costs that have been demonstrably incurred in this proceeding and were necessary and proper for its conduct, was 50% of Ms Harris' estimate. The applicants further contended that in any event, the necessary and proper costs could rise no higher than Ms Harris' estimate.
