Factual background
4On 11 January 2013, the plaintiff as Owner and the first defendant as Principal Contractor entered into a Principal Contractor Contract ("the Contract") whereby the first defendant agreed to construct a mixed use development at a site in Five Dock for a stated Contract Price of $6,400,000 (excluding GST). The contract was varied by an Amendment Deed entered into on 20 March 2013.
5Payment to the first defendant is primarily dealt with in clause 12 of the Contract, which relevantly provides:
"12.1 Subject to clause 12.19 and to any other right to set off which the Owner may have, the Owner must pay the Contractor:
(a) the Contract Price; and
(b) any other amounts which are payable by the Owner to the Contractor under the Contract.
12.2 For the avoidance of doubt, this clause 12 is subject to the Owner's right to retain retention moneys as described in the Contract Particulars.
[...]
12.6 In order for any payment to be valid, the Contractor must:
(a) only claim an amount to the value of 80% of works completed to the date of the claim, except for the final claim which will be an amount to the value of 100% of the Contract Price, including approved Variations; and
(b) must give the Contract Administrator claims for payment on account of the Contract Price and any other amounts payable by the Owner to the Contractor under the Contract:
(i) at the times stated, or upon completion of the milestones described, in the Contract Particulars;
(ii) within the times required by clauses 12.13 and 12.15; and
(iii) in the format the Contract Administrator reasonably requires, which includes:
A. evidence from a quantity surveyor, approved by and paid for by the Contract Administrator, of the value of work completed in accordance with the Contract. The value determined by the quantity surveyor shall be accepted as final; and
B. written confirmation that the work has been completed in a proper and workmanlike manner by an architect, approved by and paid for, by the Contract Administrator.
The Contractor cannot include in any payment claim under this clause 12.6, a Claim which is barred by clause 16.5.
[...]
12.7 The Contract Administrator may, if deemed necessary by the Contract Administrator, within the time period stated in the Contract Particulars of receiving a payment claim under clause 12.6 give the Contractor and the Owner a payment statement which sets out the Contract Administrator's determination as to:
(a) the value of work completed in accordance with the Contract;
(b) the amount already paid to the Contractor;
[...]
(d) the amount then payable by the Owner to the Contractor on account of the Contract Price and otherwise under the Contract,
together with the reasons for any difference in the amount set out as then payable from the amount in the Contractor's payment claim. [...]
12.8 Subject to clauses 12.12 and 12.19, the Owner must within the time period stated in the Contract Particulars of receiving a payment claim or statement (as applicable), pay the Contractor the amount set out as then payable in the payment statement, less any amounts disclosed as unpaid under clause 12.20.
The Owner is not obliged to pay any amounts disclosed as unpaid under clause 12.20 until the Contractor produces evidence to the reasonable satisfaction of the Contract Administrator that the amounts have been paid to the relevant persons.
[...]
12.12 The Owner is not obliged to make a payment under clause 12.8 unless the Contractor has:
[...]
(e) complied with clause 12.20.
12.13 Within 28 days of the issue of a Notice of Completion for the Works or a Stage the Contractor must give the Contract Administrator:
(a) a payment claim which must include all amounts which the Contractor claims from the Owner on account of the Contract Price or otherwise under the Contract; and
(b) notice of any other amounts which the Contractor claims from the Owner, in respect of any fact, matter or thing arising out of, or in any way in connection with, the Contractor's Activities or the Contract which:
(c) in the case of the Works, occurred prior to the Date of Completion of the Works; or
(d) in the case of a Stage, occurred prior to the Date of Completion of the Stage, insofar as the fact, matter or thing relates to the Stage.
[...]
12.15 Within 28 days after the end of the Defects Liability Period for the Works or a Stage, the Contractor must give the Contract Administrator:
(a) a payment claim which must include all amounts which the Contractor claims from the Owner on account of the Contract Price or otherwise under the Contract; and
(b) notice of any other amounts which the Contractor claims from the Owner,
In respect of any fact, matter or thing arising out of, or in any way in connection with, the Contractor's Activities or the Contract which:
(c) in the case of the Works, occurred during the Defects Liability Period for the Works; or
(d) in the case of a Stage, occurred during the Defects Liability Period for the Stage, insofar as the fact, matter or thing relates to the Stage.
[...]
12.20 The Contractor must with each payment claim under clause 12.6 provide the Contract Administrator with:
(a) a statutory declaration, together with any supporting evidence which may be reasonably required by the Contract Administrator, duly signed by the Contractor or, where the Contractor is a corporation, by a representative of the Contractor who is in a position to know the facts declared, that, except to the extent disclosed in the statutory declaration (such disclosure to specify all relevant amounts, workers and subcontractors):
(i) all workers who have at any time been employed by the Contractor on the Contractor's Activities have at the date of the payment claim been paid all moneys due and payable to them in respect of their employment on the Contractor's Activities; and
(ii) all subcontractors have been paid all moneys due and payable to them in respect of the Contractor's Activities;
(b) a Subcontractor's Statement in the form attached at Schedule 2 (as amended from time to time); and
(c) any other documentary evidence required by the Contract Administrator that, except to the extent otherwise disclosed (such disclosure to specify all relevant amounts and workers), as at the date of the payment claim, all workers who have been employed by a subcontractor of the Contractor have been paid all moneys due and payable to them in respect of their employment on the Contractor's Activities."
6The Contract Particulars specify "Monthly on the 15th day of each month" in relation to claims for payment under clause 12.6(b)(i).
7Termination of the Contract is dealt with in clause 14 which relevantly provides:
"14.1 Subject to clause 14.7, nothing in this clause 14 or that a party does or fails to do pursuant to this clause 14 will prejudice the right of that party to exercise any right or remedy (including recovering damages) which it may have when the other party breaches (including repudiates) the Contract.
14.2 The Owner may give a written notice under clause 14.4 to the Contractor, if the Contractor:
[...]
(g) is otherwise in substantial breach of the Contract.
[...]
14.4 A notice under this clause 14.4 must state:
(a) that it is a notice under clause 14.4;
(b) the breach relied upon; and
(c) that the party giving the notice requires the other party to remedy the breach within 21 days of receiving the notice.
14.5 If:
[...]
(b) a party does not remedy a breach of Contract the subject of a notice under clause 14.4 within 21 days of receiving the notice under clause 14.4,
then:
(c) where that party is the Contractor, the Owner may by written notice to the Contractor terminate the Contract;
[...]
14.6 Subject to clause 14.1, if the Owner terminates the contract under clause 14.5 or if the Contractor repudiates the Contract and the Owner otherwise terminates the Contract:
(a) the Owner will:
[...]
(iii) not be obliged to make any further payments to the Contractor, including any money the subject of a payment claim under clause 12.6 or a payment statement under clause 0 [sic];
[...]
14.8 Clauses 14.8 and 14.9 do not apply unless otherwise stated in the Contract Particulars.
Without prejudice to any of the Owner's other rights under this Contract, the Owner may:
(a) at any time for its sole convenience, and for any reason, by written notice to the Contractor terminate the Contract effective from the time stated in the Owner's notice or if no such time is stated, at the time the notice is given to the Contract; and
(b) thereafter, at its absolute discretion, complete the uncompleted part of the Works either itself or by engaging Other Contractors.
14.9 If the Owner terminates the Contract under clause 14.8, the Contractor:
(a) will be entitled to payment of the following amounts as determined by the Contract Administrator:
(i) for work carried out prior to the date of termination the amount which would have been payable if the Contract had not been terminated and the Contractor submitted a payment claim for work carried out to the date of termination;
(ii) the cost of goods or materials reasonably ordered by the Contractor for the Works for which the Contractor is legally bound to pay provided that:
A. the value of the goods or materials is not included in the amount payable under sub-paragraph (i) and
B. title in the goods and the materials will vest in the Owner upon payment;
(iii) the reasonable cost of removing from the Site all labour, Plant, Equipment and Work and other things used in the Contractor's Activities; and
(iv) the amount specified in the Contract Particulars;
[...]
The amount to which the Contractor is entitled under this clause 14.9 will be a limitation upon the Owner's liability to the Contractor arising out of, or in any way in connection with, the termination of the Contract and the Contractor may not make any Claim against the Owner arising out of, or in any way in connection with, the termination of the Contract other than for the amount payable under this clause 14.9.
This clause 14.9 will survive the termination of the Contract by the Owner under clause 14.8."
8The Contract Particulars indicate that the clauses relating to termination for the Owner's convenience apply. No amount is specified in the Contract Particulars for the purposes of clause 14.9(a)(iv).
9The provisions of the Contract Particulars concerning clause 12.2 and retention monies were varied by the Amendment Deed so that it was henceforth provided:
"5% of Contract Price (plus GST) is retained as follows:
10% of the value of each payment claim is retained by the Contract Administrator until an accumulative value of 5% of the Contract Price (plus GST) has been retained.
Retention money is released as follows:
5% retention of Contract Price (plus GST) to be released upon:
1.Completion of the Works, free from any Defects;
2.the Owner receiving a final occupation certificate from City of Canada Bay Council for the Works; and
3.the Guaranteed Sum [sic - is delivered?] in accordance with clause 19; and
The Guaranteed Sum to be released 12 months after the date of the final occupation certificate, subject to all defects being completely rectified."
10Clause 19.1 of the Contract provides for the Contractor, on or by the date of Completion, to obtain and deliver to the Owner a bank guarantee for the sum of $176,000 (being 2.5% of the Contract Price).
11During the course of the performance of the Contract, the first defendant submitted a number of payment claims expressed to be made under the Act. As required by clause 12.20 of the Contract, each of those claims was accompanied by a statutory declaration made by the first defendant concerning the payment of sub-contractors.
12The first seven payment claims, which were dated the 15th day of each month from February 2013 to August 2013, were paid in full by the plaintiff. Difficulties emerged in late August 2013 when it became apparent to the plaintiff that the first defendant was having difficulty making payments that were due to the various contractors and suppliers providing goods and services for the development.
13On about 29 August 2013 the first defendant told Mr Brian Metledge (a director of the plaintiff who was, along with Mr Albert Metledge, the Contract Administrator) that he had a cashflow problem and needed help. The first defendant requested the plaintiff to pay some of the contractors and suppliers directly, as he was unable to do so. On 30 August 2013 the first defendant sent an email to Brian Metledge which included the following:
"As per our discussions yesterday afternoon. I will need you to take over payments to subcontractors and suppliers for money currently owing and for future payments for all existing subcontractors as well as new ones.
This decision has been made in the best interest of the project and its progress.
Please access funds for Monday next week so we can get the subcontractors and suppliers paid on Monday and Tuesday next week so that the job will continue without any delays.
I have requested all subcontractors and suppliers to forward a stat dec with payments received. I will follow them up and pass these onto you once received."
14From early September 2013 the first defendant commenced providing information to the plaintiff about what had been paid to, and what remained outstanding, in relation to various contractors and suppliers, and made many requests that the plaintiff pay the outstanding amounts. From about 6 September 2013, the plaintiff made payments directly to a number of those entities.
15Discussions followed between the parties about what to do about the Contract. By 28 October 2013, the plaintiff was indicating that unless a mutual agreement was reached to end the relationship amicably, the plaintiff would need to exercise rights under the Contract, including the right to terminate.
16On 11 November 2013, the first defendant submitted payment claims 8 and 9 dated 15 September 2013 and 15 October 2013 respectively. On 14 November 2013, solicitors then acting for the first defendant wrote to the plaintiff. The letter contained allegations that the plaintiff was in breach of the Contract by failing to cooperate, including by interfering with subcontractors and suppliers. It was also alleged that the plaintiff was in breach by failing to pay payment claim 8. The letter disclosed that the first defendant had only one subcontractor, namely, Saferway Constructions Pty Ltd, and that the first defendant did not owe it any money in relation to the project. The letter further disclosed that Saferway Constructions Pty Ltd had debts totalling more than $907,000 to its subcontractors on the project.
17Saferway Constructions Pty Ltd is a company of which the first defendant is the sole director and shareholder. It was incorporated in December 2012.
18At 3:32pm on 15 November 2013, the plaintiff sent an email to the first defendant attaching a Notice of Termination of the Contract. The notice recited numerous alleged breaches by the first defendant, said to amount to a repudiation of the Contract such as to entitle the plaintiff to terminate the Contract.
19At 3:36pm on 15 November 2013, the plaintiff sent a further email to the first defendant attaching a Notice of Termination of the Contract. This notice was expressed to be given pursuant to the termination for convenience provisions of clause 14.8 of the Contract.
20About half an hour later, the first defendant submitted payment claim 10 dated 15 November 2013. The total amount claimed was $1,995,658.19. That amount did not include the retention moneys which were stated to be $233,773.47.
21On 22 November 2013, solicitors then acting for the first defendant wrote to the solicitors then acting for the plaintiff. The letter included a statement that the first defendant relied on clause 14.9 of the Contract and claimed:
"1 In accordance with clause 14.9(a)(i) our client seeks payment of claim 10 for work complete prior to termination on 15 November 2013;
2 In accordance with clause 14.9(a)(ii), the costs of the materials left on site, which have not formed part of payment claim 10, this amount is calculated in the total sum of $130,000 [...]."
22The letter from the first defendant's solicitors further stated that it was the first defendant's position that the Contract had either been terminated pursuant to clause 14.8 for convenience, or else remained on foot.
23Payment claim 10 was not paid, and the first defendant made an application for adjudication under the Act. In its Adjudication Application, the first defendant contended that the plaintiff was in breach of clause 14.9, including by failing to meet payment claim 10. Ultimately, an adjudication determination under the Act was given by Mr Damian Michael on 31 January 2014. He determined that the amount to be paid by the plaintiff to the first defendant was $842,915.72.
24In the course of his lengthy determination, Mr Michael found that the Contract had been terminated by the plaintiff for convenience under clause 14.8. He further found that 15 November 2013 was the relevant reference date for the progress payment as that date had already accrued by the time the Notice of Termination under clause 14.8 had been served.
25The plaintiff paid the adjudicated amount to the first defendant on 14 February 2014. There is no evidence that the first defendant paid any of the money to Saferway Constructions Pty Ltd, or directly to any contractor or supplier in relation to the Five Dock project.
26On 4 March 2014, a special resolution of Saferway Pty Ltd was passed pursuant to s 491 of the Corporations Act 2001 (Cth) for the voluntary winding up of the Company. The liquidator's initial report to creditors noted a deficiency of assets to liabilities in the sum of $1,673,052. A number of the named creditors appear to be contractors or suppliers in relation to the project.
27On 23 July 2014, the first defendant submitted payment claim 11. The claim was stated to be made under the Act "for a progress payment on account of the amount to which our company is entitled under clause 14.9 of the Contract". The claimed amount was $960,037.67 (including GST), consisting of four components.
28The first component, of $326,037.66, was calculated on the basis of the total valuation of the work (including variations) as determined by Mr Michael, less defects and other deductions found by Mr Michael, and less the amount already received (again as determined by Mr Michael) and Mr Michael's adjudicated amount.
29The second component was a claimed credit of $180,200 in respect of a Schindler lift together with $27,033, being a 15% margin for that item.
30The third component was $158,508.31 for materials left on site, and the fourth component was $180,982.54 for variations not previously claimed.
31On 6 August 2014, the plaintiff served a payment schedule in response to claim 11. The plaintiff stated that it did not propose to make any payment. Numerous arguments were raised by the plaintiff, including that the claim was not a payment claim under the Act because there was no reference date in relation to which the claim could be made. The plaintiff also contended that no claim could be made under clause 14.9 of the Contract in circumstances where the first defendant had already made a payment claim for work carried out up to 15 November 2013, the date of termination of the Contract.
32On about 19 August 2014, the first defendant made an application for adjudication under the Act. In this application, the first defendant described the claim for the first component (now adjusted down to $320,000) as a claim for the retention moneys. The first defendant had not previously described the claim in that fashion. The third and fourth components were reduced to $96,246 and $155,402 respectively, bringing the total amount claimed down to $856,769. The plaintiff provided its Adjudication Response on 26 August 2014.
33As noted earlier, the second defendant gave her adjudication determination on 16 September 2014. She determined that the amount that the plaintiff should pay to the first defendant was $179,221.74 (including GST).
34The second defendant accepted that the Contract had been terminated for convenience under clause 14.8, and went on to state that she was not satisfied that the first defendant had repudiated the Contract so as to entitle the plaintiff to terminate on that basis. The second defendant also accepted that for payment claim 11 to be valid, there had to be a reference date other than the reference date of 15 November 2013 which applied in relation to payment claim 10. On that issue, the second defendant concluded that there was nothing in the Contract which provided for reference dates to cease upon termination, so (in accordance with s 8(2)(b) of the Act) further reference dates arose on 30 November 2013 and on the last day of each month thereafter. The second defendant did not expressly deal with the argument that no claim could be made under clause 14.9 because the first defendant had already made a claim for work carried out up to the date of termination.
35In summary, the second defendant determined that, after allowing for some further defects and omissions, the first defendant should be paid the full value of the work performed, together with $30,000 for materials left on site, $1,200 for removal of plant and equipment, and $3,359.09 for variations not previously claimed.
