The background facts
4 The professional activity of the insured was water treatment engineering.
5 Prior to March 2006, when the insured commenced the work, it entered into a design and construct contract that was relevantly summarised by the primary judge at [6] of her reasons:
The works that Aquagenics contracted to perform for the Council included the detailed design, construction, testing, commissioning and process proving of a wastewater treatment plant with a design capacity of 1500kl\day for the price of $5,477,300.00. The contract comprised of a series of documents which passed between the parties. It required Aquagenics, amongst other things, to undertake "pre commissioning" as defined in clause 27 of the tender documents prior to the diversion of wastewater to the new wastewater treatment plant; "commissioning" of the plant in accordance with the requirements of clause 28; and to undertake "process proving" of the plant in accordance with clause 30. The contract also incorporated the general conditions of contract for design and construct in AS 4300-1995. It is relevant to note clause 44 of those general conditions which was relied on by the Council in its dispute with Aquagenics which went to arbitration:
• clause 44.2 provides that if the contractor commits a substantial breach of contract and the principal considers that damages may not be an adequate remedy, the principal may give the contractor a written notice to show cause;
• clause 44.3 sets out the requirements of a notice to show cause which includes specifying the alleged substantial breach and requires the contractor to show cause in writing why the principal should not exercise a right referred to in clause 44.4;
• the right referred to in clause 44.4 is the right of the principal by notice in writing to the contractor to "take out of the hands of the contractor the whole or part of the work remaining to be completed", if by the time specified in a notice given under clause 44.2 the contractor fails to show reasonable cause why the principal should not exercise that right; and
• clause 44.6 provides that when work taken out of the hands of the contractor under clause 44.4 is completed, if the cost incurred by the principal is greater than the amount which would have been paid to the contractor if the work had been completed by the contractor, "the difference shall be a debt due from the Contractor to the Principal".
6 Clauses 27 and 28 of the contract involved, on their face, contractual obligations involving technical and engineering expertise. For example, cl 27.2 provided that pre-commissioning included the following:
a) A static and dimensional inspection to establish that all items of equipment are complete and that the equipment is ready for no-load operation.
b) No-load operation to demonstrate that all equipment functions successfully, both separately and as components of integrated systems.
c) Submission of draft Operation and Maintenance Manuals for all mechanical and electrical equipment.
…
g) Checking the operational integrity of safety devices.
h) Adjustments and setting of all no-flow and torque limit switches.
i) Operation of all mechanical and electrical equipment.
…
7 Clause 28.2 provided that commissioning included the following:
a) Design load/acceptance operation to demonstrate that all equipment and systems eg. screenings and grit systems, sludge handling systems, odour control etc. can be successfully and reliably operated under working conditions.
b) Submission of final Operation and Maintenance manuals.
c) Submission of any outstanding "as-constructed" records for all work under the Contract including resubmission of any "as-constructed" drawings that may require amendment as a result of changes during the commissioning process.
d) Undertake process and effluent testing.
e) Continuous operation of the whole of the Works for fourteen (14) consecutive days without any faults. During this period, if any of the following occur, the fourteen (14) day test shall be recommenced for a further fourteen consecutive (14) days, after the fault has been rectified:
1) Any process or system does not function as specified
2) Any mechanical or electrical equipment does not perform as specified
3) Exceeds the effluent quality requirements of regulatory requirements for the new WWTP. Undertake daily sampling and analysis for these parameters during this fourteen day period to demonstrate compliance with this requirement.
4) Operation of backup equipment without fault for five (5) consecutive days during the fourteen (14) days test period.
5) Establishment of the treatment process, if necessary by "seeding" with biological matter. Council will arrange for this to be made available by contacting the Council.
6) Any other fault that the Superintendent deems sufficient to warrant the 14 days continuous operation test to be re-started.
8 In May and June 2007, a dispute arose between the parties (the insured and the Council), the nature and immediate consequences of which were succinctly and uncontroversially set out by the primary judge at [8] to [20] of her reasons, which we adopt:
8 In May/June 2007, a dispute arose between Aquagenics and the Council over whether Aquagenics had conducted the pre-commissioning tests it was required to conduct under the terms of the contract. In short compass, Aquagenics maintained that it had undertaken the required pre-commissioning and that it was ready to commence commissioning by way of "seeding". Under the contract, the Council was responsible for delivering the seed sludge for the establishment of the treatment process but refused to do so, claiming that Aquagenics had failed to undertake pre commissioning as required by the contract. The disagreement culminated in a site meeting on 6 June 2007 between representatives of the Council and Aquagenics but no agreement was reached. Mr Bill Day, the then managing director of Aquagenics, advised that Aquagenics was leaving the site as no further work was possible until sludge was available for seeding. Aquagenics never returned to the site and did no further work.
9 On 29 June 2007, Aquagenics made a demand on the Council for an extension of time for completion of the works, asserting that the extension of time was required by reason of the Council's delay in delivering the seed sludge necessary for commissioning.
10 On 30 July 2007, the Council gave Aquagenics notice to show cause pursuant to clause 44.2 of the general conditions of the contract ("the July show cause notice"). The July show cause notice was in the following terms:
This is a notice pursuant to clause 44 of the General Conditions of Contract, Australian Standard 4300-1995, which forms part of an agreement between the Break O'Day Council and you which is dated 23 February 2006 and is in respect of the St Helens Wastewater Treatment Plant (the contract).
Pursuant to clause 44.2 the Break O'Day Council gives you notice that you have committed a substantial breach of contract and that it considers that damages may not be an adequate remedy. The particulars of the breach of contract are as follows:
1. You have failed to submit three copies of draft maintenance schedules at least 8 weeks before pre-commissioning in accordance with clause 26.4(a) of the tender document prepared by SKM dated March 2005 (a tender document);
2. You have failed to submit five complete sets of a draft operation manual and maintenance manuals at least 8-weeks before pre-commissioning pursuant to clause 26.4(b) of the tender document;
3. You have failed to undertake pre-commissioning as required by clause 27.1 of the tender documents;
4. You have failed to prepare and submit a detailed pre commissioning program including formation of pre-commissioning team, pre-commissioning team meetings and inspection and test plans and to submit that documentation to the superintendent 8-weeks prior to the commencement of pre commissioning as required by clause 27.2 of the tender documents;
5. You have failed to undertake pre-commissioning as required by subparagraphs (a) - (t) inclusive of clause 27.2 of the tender documents;
6. You have failed to submit a report to the superintendent on satisfactory completion of pre commissioning in accordance with clause 27.4 of the tender documents.
The Break O'Day Council gives you notice in accordance with clause 44.3 of the general conditions of the contract as follows:
(a) this is a notice pursuant to clause 44 of the general conditions of contract;
(b) the alleged substantial breaches of contract by you are as particularised above;
(c) the Break O'Day Council requires you to show cause in writing why it should not exercise a right referred to in clause 44.4 of the general conditions of contract;
(d) you must show cause within 14-days of the service of this notice upon you;
(e) the place at which cause must be shown is by written notice addressed to the Break O'Day Council 1 Cecilia Street, St Helens, Tasmania, 7216.
11 Aquagenics responded by letter dated 13 August 2007 asserting that it had carried out pre commissioning in accordance with the contract specifications and that it had not committed any substantial breaches of contract.
12 On 30 August 2007, the Council gave Aquagenics notice of the exercise of its rights under clause 44.4 ("the 30 August 2007 letter") as follows:
I refer to our formal notice to you of 30 July 2007 and to your response of 13 August 2007.
The Break O'Day Council does not consider that you have shown reasonable cause why it should not exercise its rights pursuant to clause 44.4 of the contract. Your notice is largely argumentative, contains factual misstatements and does not deal with the critical issues concerning your failure to undertake pre-commissioning as set out in our notice of 30 July 2007.
Accordingly I give you notice that the Break O'Day Council has decided to take out of your hands the pre commissioning and commissioning works required by the contract and will engage another person to attend to these contractual obligations.
The Break O'Day Council reserves all of its rights to claim damages/compensation against you in respect of your breach of contract and of the costs of having the works undertaken by another person.
13 With effect from 30 August 2007, the Council took the completion of the pre-commissioning and commissioning works under the contract out of the hands of Aquagenics. The Council then completed and/or corrected some of the remaining work using its own employed staff and engaged contractors to complete the remaining work.
14 In the meantime, Aquagenics disputed that the Council had an entitlement to take the contract work out of Aquagenics' hands under clause 44 of the contract and asserted that the Council was in serious breach of the contract. On 14 September 2007, Aquagenics claimed the right to give a notice to show cause to the Council under clause 44.7 of the contract. Clause 44.7 is in equivalent terms to clause 44.2 save that the right to give a notice to show cause applies where the principal commits a substantial breach of contract and the contractor considers that damages may not be an adequate remedy.
15 On 19 September 2007, the Council's solicitors sent the following letter to Aquagenics ("the 19 September 2007 letter"):
We act on behalf of the Break O'Day Council who have provided us with your letter of 14 September 2007.
We confirm that our client adheres to the Notice provided to you on 30 July 2007 and the follow up letter of 30 August 2007 and stands by their decision that you are in breach of contract. They stand by their decision to remove the contract from your hands under the provisions of clause 44.4 and engage another contractor to undertake those works.
We confirm that the contracts for the precommissioning and the commissioning which have now been placed in the hands of another contractor is inclusive of the requirements under Section 27 and 28 and that the new contractor will supply:
a. replacement people;
b. personal training for process proving an operation; and
c. operation and maintenance.
We also confirm that we will be exercising our rights to claim damages/compensation in respect of your breach of the contract and of the costs of having the work undertaken by another entity.
16 By letter dated 28 September 2007, Aquagenics claimed that the Council's decision to take the work out of the hands of Aquagenics amounted to a repudiation of the contract and on 17 October 2007, Aquagenics gave a formal notice to the Council to show cause under clause 44.
17 The Council responded to the company's show cause notice by an undated letter which, it appears, was received by Aquagenics on 25 October 2007. In that letter the Council denied that it had committed any of the substantial breaches of contract alleged against it and maintained that Aquagenics had "acted in substantial breach of [its] contract in the ways set out" in the July show cause notice.
18 On 25 October 2007, the Council's solicitors also wrote to Aquagenics' solicitors in the following terms ("the 25 October 2007 letter"):
I refer to your letter of 28 September 2007 and to the subsequent notice to show cause, which doubtless you drafted, and which was served by your client under cover of its letter of 17 October 2007.
I want to express myself very simply and clearly. Your client is the one that has breached the contract, not mine. Your client failed to provide an adequate response to my client's notice to show cause. My client has previously advised yours of the course which it has now taken as a consequence.
Your claims that my client has breaded [sic] the contract and that as a consequence your client is entitled to have the security returned are rejected.
I will accept service of any relevant documents, proceedings or notices on behalf of my client.
19 On 5 November 2007, Aquagenics gave notice to the Council pursuant to clause 44.9 of suspension of the work under the contract.
20 On 12 December 2007, Aquagenics' lawyers gave notice of an election by Aquagenics to terminate the contract pursuant to clause 44.9 and otherwise at common law by acceptance of repudiation. Notice was subsequently given by the Council to Aquagenics that it was terminating the contract on the basis that Aquagenics' letter of 12 December 2007 was a repudiation of the contract.
9 In the following three years, the Council had the work done by other contractors. Importantly for understanding the subsequent arbitration and the insurance dispute, the Council discovered design flaws in the work that had been done by the insured before June 2007. These design flaws were not known as at June 2007.
10 In late 2010, the Council commenced arbitral proceedings. The arbitration reference commenced in March 2012. A final award was published in May 2013 in favour of the Council in the sum of $1,346,111.57 before certain credits, interest and costs.
11 The primary judge described the arbitration award at [24] to [31] of the reasons. Two central issues were adverted to in [24] of the reasons:
24 The amended points of claim filed by the Council claimed, amongst other things, that Aquagenics had:
• failed to undertake pre-commissioning and commissioning as required by the contract; and
• failed to comply with design and construction specifications under the contract.
12 The debate about pre-commissioning and commissioning was resolved at the arbitration as discussed by the primary judge at [26] to [28]:
26 A central issue in the arbitration was whether or not the pre-commissioning and commissioning works were properly taken out of the hands of Aquagenics by the Council: paragraphs [6.1] and [7.1] of the Interim Award and Reasons. Aquagenics conceded that if those works were properly taken out of its hands, then it had, by purporting to terminate the contract on 12 December 2007, repudiated the contract and exposed itself to liability for damages for the cost of the works necessary to rectify the defects.
27 The Arbitrator found that Aquagenics, due to its own default, had failed to undertake pre commissioning as required by the contract, that the breaches were substantial and, unless rectified, the Council could not have obtained its wastewater treatment plant. The Arbitrator determined that the Council had properly taken the pre-commissioning works and commissioning works out of the hands of Aquagenics. In making that finding, the Arbitrator rejected Aquagenics' case that it had satisfactorily completed all the work which it considered necessary to enable the commissioning of the plant and Aquagenics' claim that the Council had not required strict compliance with the contractual requirements.
28 In respect of Aquagenics' show cause notice to the Council, the Arbitrator found that because of Aquagenics' failure to conclude satisfactory pre-commissioning of the plant, the plant was not ready for delivery of seed sludge by 30 May 2007 and this was due to Aquagenics' default. The Arbitrator found that the absence of seed sludge delivery was therefore not a matter upon which Aquagenics could rely to avoid its commissioning obligations under clause 28 as at 30 July 2007 and Aquagenics did not have a proper basis to give its show cause notice or right to terminate the contract.
13 The arbitrator also found that Aquagenics had breached its design and construction obligations. It is important to understand that some of those breaches went to faulty design and some to so-called construction defects.
14 By May 2014, the insured was in administration. It is now in liquidation. Its administrator made a claim under the policy in respect of the damages, interest, costs and fees awarded by the arbitrator.
15 The insuring clause of the policy was as follows:
In consideration of the information that you have provided to us prior to commencement of this insurance and which is deemed to form the basis of this insurance we agree to pay on your behalf all sums which you become legally obliged to pay (including liability for claimants' costs and expenses) as a result of any claim first made against the company or entity named as the Insured in the Schedule during the period of the policy and notified to us during the period of the policy arising out of any wrongful act committed by you or on your behalf in the course of your professional activities. We will also pay costs and expenses on your behalf.
(Bolding in the original denoting a defined term)
16 The terms "claim" and "wrongful act" were defined as follows:
"Claim" means a written demand received by you for money or compensation, including the service of suit or institution of arbitration proceedings.
"Wrongful act" means any:
a) act, error or omission, misstatement or misrepresentation,
b) unintentional breach of any implied statutory term concerning necessary quality, safety or fitness,
c) unintentional breach of an implied contractual duty to use reasonable care and skill,
d) unintentional breach of warranty of authority, breach of duty, breach of trust, breach of confidence, misuse of information or breach of privacy,
e) unintentional infringement of any intellectual property right,
f) unintentional destruction of, damage to, loss or mislaying of your documents or documents in your care, custody or control,
g) libel, slander or defamation or passing off,
h) dishonesty of your employees,
i) breach of the terms of the Trade Practices Act 1974 (Cth) as well as any Fair Trading legislation of any State or Territory of Australia, but excluding any such breach which is due to conduct of yours which is fraudulent or intended to mislead or deceive.
17 Relevant exclusions were numbered 6 and 11:
We will not:
a) make any payment on your behalf for any claim, or
b) incur any costs and expenses
…
