Facts
94 From at least 1995, LSE had supplied office equipment to a range of customers in Newcastle and the region north of Newcastle in New South Wales.
95 On 7 July 1995, Capital Corporate entered into a "Principal and Agency Agreement" with LSE ("the First P&A Agreement"). Under the terms of the First P&A Agreement, LSE undertook to submit various leasing proposals to Capital Corporate from customers of LSE who were interested in leasing office equipment: cll 3.1 and 3.2. If Capital Corporate accepted the proposal, it would purchase the equipment and then lease the equipment to the customer. LSE would enter into the lease with the customer as the undisclosed agent of Capital Corporate: recital B and cl 5. The customer was not aware that Capital Corporate was the actual owner and lessor of the equipment. LSE would collect the rents from the customers on behalf of Capital Corporate and subsequently pay the rents to Capital Corporate: cll 3.3-3.4. Except in the case of insolvency of any lessee, LSE indemnified the relevant Capital Company against "any loss, cost or expense incurred by [Capital] directly as a result of the failure by any Lessee to pay any Moneys owing on the due date for payment": cll 6.2 and 6.6.
96 At the termination of each equipment lease, LSE or its customer would purchase the equipment from Capital Corporate for the previously agreed "residual amount" which was usually $1.00. The purchase was effected by payment of the residual amount: cll 11.1 and 16.1-16.4. If LSE or the customer elected to terminate the equipment lease and purchase the equipment before the lease term expired, LSE would obtain a "payout quote" from Capital Corporate. The payout amount was the sum Capital Corporate would accept for early termination of the equipment lease. The payout amount was the sum of the remaining lease payments and the residual payment discounted for early payment. Upon expiry or termination of an equipment lease in the manner outlined, ownership of the equipment would pass to the entity that had made the necessary payment - LSE or the customer, as the case may be: cll 5.9 and 11.3.
97 On 1 July 2000, Capital Finance entered into a second Principal and Agency Agreement with LSE ("the Second P&A Agreement"). It was in similar terms to the First P&A Agreement.
98 In mid December 2000, Capital Finance was advised that LSE had purported to sell to Leasetec Australia Pty Ltd ("Leasetec") photocopy equipment that was in fact owned by the Capital Companies and was the subject of the First and Second P&A Agreements. On 15 December 2000, Leasetec obtained preservation of assets orders against LSE and its principal, Mr Lloyd Scott. Subsequently, Capital Finance was joined as a defendant to those proceedings.
99 On 12 January 2001, a meeting was held with representatives of LSE, Leasetec and the Capital Companies. Two deeds were executed on that day. The First Deed was between the Capital Companies, Leasetec, LSE and Mr Scott. As the recitals to the First Deed record, it was to resolve the dispute between the Capital Companies and Leasetec in relation to the title to certain equipment, equipment that LSE had sold to both the Capital Companies and Leasetec.
100 The other deed executed on 12 January 2001 was the Second Deed between the Capital Companies, LSE and Mr Scott. The terms of the Second Deed are central to the issues on appeal. The recitals to the Second Deed recorded that:
(1) pursuant to the First and Second P&A Agreements, LSE acted as the agent of the Capital Companies on an undisclosed basis to acquire and to lease or rent equipment to persons throughout Australia requiring leasing or renting of certain equipment: recitals A and B;
(2) pursuant to the First and Second P&A Agreements, LSE collected any money it was obliged to collect from any lessee on behalf of the Capital Companies ("the Rent"), held that Rent on trust for the Capital Companies and remitted it to them: recital C; and
(3) the Capital Companies no longer wished to provide finance to the lessees under any Leasing agreement entered into by LSE as agent for one of the Capital Companies under the First or Second P&A Agreement and "wish[ed] to reduce the Exposure to nil": recital D.
101 The phrase "wish[ed] to reduce the Exposure to nil" is important. The word "Exposure" was defined in the Second Deed to mean:
"the aggregate at any given time of the Payouts under all the Leasing Agreements plus all amounts otherwise owed by LSE or Scott to [the Capital Companies] pursuant to this deed or any other agreement or deed between the parties (including any amount owing in respect of legal costs)."
"Payout" was defined to mean "the sum of money required to be paid by a Lessee under a Leasing Agreement to terminate the obligations of that Lessee under that Leasing Agreement."
102 The Second Deed achieved a number of purposes. First, it contained the acknowledgement by LSE and Mr Scott that LSE was bound and continued to be bound by the First and Second P&A Agreements and that, under those agreements, one of the Capital Companies was the legal and beneficial owner of all the equipment leased under those agreements: cl 2.1 of the Second Deed. Secondly, the Second Deed constituted the agreement by LSE that it would make certain payments to the Capital Companies including:
(1) on or before 15 January 2001 (3 days after execution of the Deed), the sum of $318,053.09 as the Monthly Rent for December 2000. The term "Monthly Rent" was defined to mean that portion of the Rent apart from what was described as "D-D Rent" which LSE was obliged to collect and remit to the Capital Companies in any given month: cll 1.1 and 3.1. (The "D-D Rent" was defined to mean that portion of the Rent which LSE was obliged to collect from lessees and remit to the Capital Companies on a daily basis: cl 1.1);
(2) on or before 24 January 2001 (some 12 days after execution of the Deed), the sum of $298,487.32 as the Monthly Rent for January 2001: cl 3.2;
(3) the D-D Rent on a daily basis: cl 3.3;
(4) until the Exposure was reduced to zero, LSE would remit the Monthly Rent in advance on the first day of each month commencing on 1 February 2001 and, on or before the 28th day of each month, the Capital Companies would notify LSE of the Rent to be remitted on the first day of the next month: cl 3.4; and
(5) reduction of the Exposure to zero: cl 4.1.
103 The last item, reduction of the Exposure to zero, was dealt with in cl 4.1 of the Second Deed. It provided:
"LSE shall reduce the Exposure and payout the LSE Leases by payment to [Capital Finance] in cleared funds, of the following amounts on the following dates:
(a) the sum of $3,000,000.00 plus the amount required to be paid by LSE to terminate its obligations to [Capital Finance] under the LSE Leases (which as at 12 January 2001 totalled $323,032.17) on or before 11 February 2001;
(b) the sum of $3,000,000.00 on or before 11 March 2001;
(c) the sum of $4,000,000.00 on or before 11 April 2001;
(d) the balance of the Exposure on or before 11 May 2001."
104 The payments in issue are those listed in [87] above: payments made on 14 February, 18 May and 31 May 2001. As this clause makes plain, those monthly payments were intended to reduce the "Exposure". The method by which, and the circumstances in which, these payments were made is also relevant to the issues on appeal. As these reasons will later show, the payments were not in satisfaction of any debt then owing whether by LSE or by any lessee who had dealt with LSE as undisclosed agent of one of the Capital Companies. The obligation to make the payments was created by the Deed and was neither a recording of any then existing obligation nor an acceleration of any future obligation of LSE.
105 In late December 2000 and early January 2001, LSE had sought to refinance the equipment leases it had proposed with both Leasetec and the Capital Companies. It approached the National Australia Bank Limited ("NAB"). Initially a form of "Sale Hireback" was proposed whereby NAB would lend the money to LSE who would pay out the equipment leases and purchase the equipment from Capital Finance. NAB was then to purchase the equipment from LSE and hire it back to LSE. That initial proposal was not adopted. Ultimately, NAB decided to purchase the equipment from Capital Finance and then lease it to LSE. To give effect to that arrangement, NAB organised for Capital Finance to prepare "Payout Quotes/Tax Invoices" for the relevant equipment rental agreements addressed to NAB.
106 On 14 February 2001, upon receipt of a "Payout Quote/Tax Invoice" addressed to it for each lease, NAB paid to Capital Finance:
(1) $837,986.18 in respect of the Capital Finance - Central Coast Area Health Service Rental Agreement;
(2) $929,927.17 in respect of the Capital Finance - Lemington Coal Mines Pty Ltd Rental Agreement; and
(3) $968,853.83 in respect of the Capital Finance - Gosford City Council Rental Agreement.
The total paid to Capital Finance by NAB was $2,736,767.18. These payments were made to Capital Finance three days after LSE was obliged to pay Capital Finance $3,000,000 under cl 4.1 of the Second Deed.
107 On 18 May 2001, again upon receipt of a "Payout Quote/Tax Invoice" addressed to it, NAB paid to Capital Finance $420,768.52 in respect of the Capital Finance - Hunter Institute of Technology Rental Agreement. Finally, on 31 May 2001, after receipt of a "Payout Quote/Tax Invoice" addressed to it for each lease, NAB paid to Capital Finance the following sums:
(1) $62,742.70 in respect of the Capital Finance - Mater Dei College Rental Agreement;
(2) $148,494.29 in respect of the Capital Finance - O'Neill and Associates Pty Ltd Rental Agreement;
(3) $74,911.78 in respect of the Capital Finance - Lemington Coal Mines Pty Ltd Rental Agreement; and
(4) $308,176.93 in respect of the Capital Finance - University of New England Rental Agreement.
By the time the payments were made by NAB to Capital Finance on 18 and 31 May 2001, the whole of the amount due under cl 4.1 of the Second Deed (namely, $10,000,000), had fallen due for payment by LSE to Capital Finance. The payments made by NAB on 18 and 31 May totalled $1,015,094.22. The total of the payments made by NAB to Capital Finance in February and May 2001 was $3,751,861.40.
108 The equipment that NAB purchased from Capital Finance was then leased to LSE subject to a Master Lease Agreement between NAB and LSE and Mr Scott dated 9 April 1999 and a Master Lease Purchase Agreement. LSE's obligations under both those agreements were secured by a registered charge in favour of NAB over all the assets and undertakings of LSE.
109 The payments made by NAB to Capital Finance under the "Payout Quotes/Tax Invoices" were described by the trial judge (at [44]) as being recorded by NAB in the following terms:
"The payments under challenge were made by arrangement with NAB through an Office Suspense Account on and after 14 February 2001 as outlined in the table reproduced above. Payments were made to Capital Finance from the Office Suspense Account which was credited with the eight payments in the period of February - May 2001. Credit was created by drawing down the lease finance account of LSE for the full amount of the lease finance, which equated to the value of the lease over its full term. The credit amount in the Office Suspense Account was then electronically transferred to Capital Finance. NAB opened a number of lease finance accounts with debit balances in the name of LSE as customer in respect of each lease, from which the amounts to be paid to Capital Finance were drawn down and credited to the Office Suspense Account. The statements indicate that NAB treated the each lease finance account as a form of borrowing. In my view, the NAB Office Suspense Account was simply a conduit through which money borrowed by LSE from NAB was paid to Capital Finance with the authority of and by arrangement between NAB and LSE. I am satisfied on the evidence that LSE authorised or directed NAB to make the challenged payments. Therefore, these payments must be treated as having been paid, not by NAB on its own account as purchaser, but under the authorisation of LSE."
(Emphasis added.)
110 The allocation by Capital Finance of the NAB payments to the "Exposure" (as that term was defined in the Second Deed) was recorded in an internal memorandum dated 15 June 2001, some 10 days before LSE was placed into administration, which recorded that the "[i]nitial funding for the refinance was principally via cash advances to LSE by the NAB". Moreover, the informal proof of debt lodged by Capital Finance for "leasing finance" was only in the sum of $7,162,151.84. That proof of debt did not include any of the amounts listed in [106] and [107] above which Capital Finance applied in satisfaction of part of LSE's obligations under the Second Deed.
111 It was common ground that:
(1) LSE was insolvent on the date of execution of the Second Deed (12 January 2001) and on the date of each payment; and
(2) immediately prior to each NAB payment and the subsequent lease to LSE, the then existing liabilities of LSE to NAB secured by the charge already exceeded the realisable value of all assets owned by LSE at that date.
