5 On 28 February 2008, Blake Dawson sent an email to Deacons asking what was the amount "allegedly" secured by the mortgage and the applicable interest rate. Deacons responded by letter dated 3 March 2008.
6 In the meantime, on 21 February, following leave granted by Goldberg J, the receivers filed an interlocutory process seeking by exercise of the Court's powers under s 601EE(2) of the Corporations Act 2001 (Cth) and s 23 of the Federal Court of Australia Act 1976 (Cth) to compel the second mortgagees to provide a discharge of the mortgage without payment of any amounts due to the second mortgagees. On 5 March 2008, the receivers filed their outline of submissions in support of their interlocutory application. Paragraph 32 of those submissions states that the receivers "are not at present willing to agree to pay to AVS any amount in consideration of a discharge of the mortgage unless so authorised and directed by the Court".
7 At a directions hearing on 6 March 2008, the learned primary judge expressed some concern about the Court's powers to compel the execution of a discharge where the amount due to the mortgagee was not ascertained and added,
And the only way that I know that [the amount due] could be ascertained is in a proceeding that calls for the taking of accounts.
8 The transcript of the hearing supports the appellant's submission that there had not, at least to that point, been any tender of the amount due to the appellant. Mr Van Hattem, senior counsel for the receivers, made the point that it was impossible to tender the amount required to satisfy both mortgages because the amounts claimed by the first and second mortgagees "far exceed the proceeds of sale". Later in the hearing his Honour said:
[T]his strikes me as a perfectly good example of a set of circumstances where a mortgagor would be entitled, as of right, to an order for the taking of accounts for the purposes of determining how much is secured by the mortgage. … And the court works out, and it says, here's your certificate for what's due, pay that, and you get a discharge.
9 Mr Martindale, senior counsel for the appellant, argued that there should be an offer to redeem "before you get to a taking of accounts between the mortgagor and mortgagee". Following some discussion his Honour indicated that as a condition of ordering the mortgagee to provide a discharge he would be prepared to order that the money be paid into court or some other account depending on the interest rate. His Honour said to Mr Martindale, "my principal concern is to make sure that you are properly protected".
10 Mr Martindale expressed some concern about the calculation of interest and made the point, several times, that until 28 February 2008 the second mortgagees had not been asked for a payout figure. His Honour indicated that this could be dealt with later and said that he could allow the sale to go ahead and that the Court could protect the mortgagees by "interim relief outside an old fashioned redemption action". Mr Martindale further made the point that there had been no offer to redeem. The transcript of the hearing shows that, consistent with Mr Van Hattem's position above at [8], at no time during this exchange did the representatives of the receivers rise to suggest that there had been a tender on behalf of the mortgagor or that the second mortgagees had waived the necessity for tender.
11 On 13 March 2008 the learned primary judge ordered, inter alia, that "At the time and place appointed for the completion of the sale of the Mews land" the second mortgagees were to deliver to the solicitors for the receivers, "a duly executed discharge of the mortgage in registrable form". His Honour also ordered that after payment of the amount due to the National Bank and the costs and expenses of the sale, the balance of the proceeds of sale was to be paid into an interest bearing account in the name of the receivers (Receivership Account). The Receivership Account had been established pursuant to order 15 (a) made by the primary judge on 28 November 2006. Payment into the Receivership Account was made on 17 March 2008. The learned primary judge did not publish his reasons for making the orders of 13 March.
12 On 18 September 2008 the learned primary judge ordered that the receivers pay to the appellant from the funds held in the Receivership Account, the amount of $4,100,282.64 in respect of the principal owing and "interest on the principal until 17 March 2008" in the amount of $1,573,613.32. Those amounts were paid to AVS on 22 September 2008. AVS then sought an additional amount of interest in respect of the period from 17 March to 22 September 2008. This brings us to the primary judgment.
