Pre-judgment Interest - The Period over which Pre-judgment Interest Runs
17 Interest should run from the date the cause of action arises, unless good cause is shown to the contrary: s 51A(1)(a). The appellants' cause of action arose on the date the second respondent converted the Additional Goods, which was 7 April 2009. Whilst the appellants did not make a demand in respect of the Additional Goods until 18 August 2009 or make a claim for conversion of the Additional goods until 18 December 2009, that is not in our opinion a reason to find that there is good cause why interest should not run from the date the FCA suggests: Kazar v Kargarian (2011) 197 FCR 113 at [96]-[97].
18 Pre-judgment interest runs until "the date as of which judgment is entered": s 51A(1)(a). For the reasons which follow, in our view, judgment has not been entered in relation to the Additional Goods. There are three alternative dates on which it might be suggested that "judgment is entered" or should be taken to have been entered:
1. 10 June 2011, when the trial judge dismissed the appellants' claims;
2. 12 December 2011, when this Court ordered that the appeal be allowed and that the appellants bring forward short minutes of order; or
3. some future date on which judgment for the appellants is "entered".
19 First, the relevant date cannot be 10 June 2011. This Court has the power to, among other things, affirm, reverse or vary a judgment at first instance: s 28 of the FCA. There is an important distinction between an affirmation of the trial judge's decision, on the one hand, and a reversal or a variation, on the other. In the latter case, "[t]he judgment is not ipso facto antedated by reason that it is substituted for the judgment in the Court below": Borthwick v The Elderslie Steamship Company Limited (No 2) [1905] 2 KB 516 at 519; cited in Nicol v Allyacht Spars Pty Ltd (No 2) (1988) 165 CLR 306 at 309-10. In this case, the judgment of this Court effectively reversed the decision of the trial judge, at least with respect to the second respondent. For that reason, the relevant date is not the date on which the trial judge dismissed the appellants' claims.
20 Second, the relevant date cannot be 12 December 2011. Section 51A(1)(a) refers to "the date as of which the judgment is entered". It is important to distinguish, as a matter or parlance, between the giving of judgment, on the one hand, and the entry or authentication of judgment, on the other: see Holtby v Hodgson (1889) 24 QBD 103 at 107. Division 39.4 of the Rules governs the entry of judgments and orders. The parties did not address submissions or argument as to when the Court's 12 December 2011 orders were "entered" in that sense. That question is irrelevant for present purposes, however, because the decision of this Court on 12 December 2011 did no more than allow the appeal and request that the appellants bring forward short minutes of order. Even if this Court's 12 December 2011 judgment was capable of being entered, that judgment did not order the second respondent to pay the appellants any sum of money upon which interest could be calculated. While we stated at [80] that "we would allow the appeal and enter a judgment for M3G in the amount claimed", the orders contemplated that the appellants would bring forward a short minute of orders to reflect that decision and that it would be those further orders which actually effected the judgment. That has not yet occurred. As s 51A(1) makes clear, a judgment including pre-judgment interest must expressly calculate and incorporate that amount or order that there be included in the sum for which judgment is given a lump sum in lieu of any such interest. Having not done so, it cannot be the case that this Court's 12 December 2011 judgment gave rise to an obligation upon the second respondent to pay damages, including pre-judgment interest, which was capable of being "entered".
21 For the reasons given, interest should run from the date the cause of action arose, 7 April 2009, until the date upon which this judgment is entered by this Court for an amount which includes pre-judgment interest.
