The relevant legal provisions
24Ms Castle's submission that Williams DCJ's orders are ambiguous, or alternatively made on an occasion where his Honour had no power to do so, arise from the interrelation of rr 42.2 and 42.7 UCPR. UCPR r 42.2 provides:
"42.2 General rule as to assessment of costs
Unless the court orders otherwise or these rules otherwise provide, costs payable to a person under an order of the court or these rules are to be assessed on the ordinary basis."
25UCPR r 42.7 provides:
"42.7 Interlocutory applications and reserved costs
(1) Unless the court orders otherwise, the costs of any application or other step in any proceedings, including:
(a) costs that are reserved, and
(b) costs in respect of any such application or step in respect of which no order as to costs is made,
are to be paid and otherwise dealt with in the same way as the general costs of the proceedings.
(2) Unless the court orders otherwise, costs referred to in subrule (1) do not become payable until the conclusion of the proceedings."
26When a court makes an order for costs, the first question is liability for costs (namely which party), and the second is the basis upon which those costs will be assessed. Ms Castle submits that, once the basis for assessment has been determined (for example, an application for indemnity costs has been refused), it is a finding based on the merits and the order made will stand unless specifically set aside; both the issues of liability for costs and the basis of the assessment are res judicata and the defendants are estopped from seeking indemnity costs without first setting aside the orders made on the ordinary basis.
27In the present case, the orders made in relation to the refusal of indemnity costs take effect from the date on which they were given (UCPR r 36.4(1)), namely 9 September and 22 October 2010 and cannot be set aside or varied in the absence of specific application to do so. Such orders include costs orders, for the reasons explained by McColl JA in Zepinic v Chateau Constructions (Aust) Ltd (No 2) [2013] NSWCA 227 at [76]-[79]. Although McColl JA noted that entry of judgment on a filed certificate of a costs assessor or Review Panel is a ministerial act, rather than a judgment of the court, this does not alter the legal effect of the order (see Frumar v Owners of Strata Plan 36957 [2010] NSWCA 172 at [40] and [42]). This means that unless the Court orders otherwise, a judgment or order is taken to be entered when it is recorded in the Court's computerised court record system: UCPR r 36.11(2). Such a judgment or order may be set aside only in the circumstances set out in UCPR r 36.15 (where judgment is given or made irregularly, illegally or against good faith) or if an application is made within 14 days (UCPR r 36.16(3A) and (3B)). Williams DCJ could not therefore set aside these orders.
28Alternatively, it is submitted that the relevant judgments and orders for costs given on 9 September and 22 October 2010 respectively must stand unless set aside, a step the defendants failed to ask Williams DCJ to take.
29Further in the alternative, it is submitted that Ms Penson did draw his Honour's attention to these earlier costs orders, in that Ms Penson (on the company's behalf) asked that they should not be set aside. It is on this basis that it is asserted that order (3) made by Williams DCJ, namely that the court was "not prepared to vary the previous costs orders made in favour of the plaintiff company" must be in error. What his Honour was doing was refusing to vary all of the costs orders, and not merely those costs orders made in favour of the plaintiff company (of which there was only one), but also the costs orders made in favour of the defendants by Judicial Registrar Smith and Letherbarrow SC DCJ. In other words, Williams DCJ did consider the application by Ms Penson to set the orders aside, and intended to make orders to that effect (by referring to "orders" in the plural). His Honour's orders are further in error, in that order 2 wrongly states that all costs after the date of the offer of compromise are to be paid on an indemnity basis, namely 26 February 2010, when what was intended was to exclude these orders.
30Ms Castle submits that the Costs Assessor and Costs Review Panel each misinterpreted orders 2 and 3 and should have accepted her clients' interpretation or alternatively looked behind the orders to determine what actually occurred and/or whether Williams DCJ had the power to make these orders. The Costs Review Panel should have picked up the true meaning of order 3 (from the plural word "orders") and realised that the success of Aquaqueen International Pty Ltd in opposing the order for costs to be paid on an indemnity basis was a "win" for them, and thus a costs order in its favour.
31I do not accept these submissions. Williams DCJ's orders are clear. His Honour has ordered that costs be paid on an indemnity basis from 26 February 2010 (the offer of compromise date). His Honour, for unrelated reasons, rejected the defendants' application to set aside an interlocutory costs order made in favour of Aquaqueen International Pty Ltd; this is the "costs orders" referred to in order 3. The fact that his Honour used the phrase "costs orders" in the plural needs to be read in light of his reluctance to enter into specifics about what orders had been made over the previous 18 months, and, crucially, the subsequent phrase "made in favour of the plaintiff company".
32The Notice of Motion and transcript confirm that Aquaqueen International Pty Ltd raised the issue, both by Notice of Motion and in oral submissions, but Williams DCJ was satisfied that the indemnity costs order should be made payable at least from the date of the offer. The application about which he wanted to hear was the application that Ms Penson be liable for costs although a non-party:
"ROLLO: So I will hand up the affidavit on which we rely on the accompanying exhibit and I also have a bundle of cases which - your Honour in short compass what we are seeking is firstly an order for costs to be on the indemnity basis, that is all costs awarded in favour of the first and second defendants in these proceedings and secondly an order that Ms Penson, the sole director and sole shareholder of the plaintiff be jointly and severally liable for those costs. The first ground on which we would seek that is on the basis of the rules offer that was made.
HIS HONOUR: I don't want to hear you on that aspect of it.
ROLLO: Yes your Honour so not on indemnity costs at all or on the rules offer?
HIS HONOUR: No on the rules offer I'm quite satisfied that the indemnity costs should be made payable at least from then.
ROLLO: Yes.
HIS HONOUR: The matter that I'm most concerned about is--
ROLLO: The costs against Ms Penson personally?
HIS HONOUR: Yes." (Transcript page 4)
33I am satisfied that Williams DCJ, although not specifically referring to these costs in his judgment or orders, refused the application to exclude these four costs orders from the indemnity costs order. This brings me to the issue of whether the Review Panel's award of costs for the four appearances set out in paragraph 1 of this judgment, on an indemnity basis rather than on the ordinary basis, amounts to an error of law.
