The evidence
27In approaching the issues raised on appeal, it is necessary to go into some detail about the facts.
28By letter dated 11 February 2009, the Department of Planning notified direct to the appellant the "Director-General's environmental assessment requirements (DGRs)" for the proposed construction. The appellant had been advised by another firm of architects during the process that culminated in the issue of the 11 February 2009 letter.
29As well as notifying the Director-General's environmental assessment requirements (which were set out in an attachment of five pages), the letter of 11 February 2009 outlined the procedure under which the appellant might lodge an "environmental assessment" (with a view to compliance with or satisfaction of the Director-General's requirements) and the Director-General, in turn, might raise issues for attention and require revision before making the environmental assessment publicly available.
30It was the receipt of the Director-General's requirements (or DGRs) and a desire to obtain the assistance of a larger architectural practice that prompted the appellant to contact the respondent in June 2009.
31The appellant dealt with Mr Swan, a director of the respondent. On 30 June 2009, he emailed to Mr Swan "the basis on which I would like you to invest in the project". Attached to the email was a document headed "Deferred Fee Investment" which set out bases on which "any investor, including consultants who defer their fees" could invest $150,000 in one or each of several units to be built and expect projected returns from that investment.
32A period of discussion and correspondence followed. There was discussion at an early stage about the need to assemble a suitable "team" of consultants. Mr Swan referred in a letter of 6 July 2009 to "the consultant team necessary to produce the EA documents and to work collaboratively with them to design the project and prepare the EA submission". Eleven different disciplines were identified as relevant or potentially relevant.
33In the same letter of 6 July 2009, Mr Swan proposed a fee of $175,000 and referred to instalments by which $125,000 of it would be payable; also:
"Upon EA approval a further immediate deferred payment of $50,000 - 10% GST. This represents AMW's financial investment in the project and incentive to achieve development approval."
34In a letter of 8 July 2009, Mr Swan emphasised that "[g]etting the EA approval is not automatic" and involved much more than "ticking the boxes set out in the DGRs".
35In a long email of 12 July 2009 to Mr Swan, the appellant said:
"From our last discussion I concluded that your quotation will get me a DA approval for the whole site and with the way prepared to move to CC, especially on Stage 1 at a further cost. You will defer 40% of your fees as quoted until 8 weeks after DA is approved."
36The email contained other references to a "DA".
37The appellant held discussions during July 2009 with Ms Lynne Sheridan, an urban planning consultant, and ultimately retained her. In a letter of 27 July 2009 to the appellant, Ms Sheridan said:
"As the town planning consultants for the project, Sheridan Planning's role will be to provide town planning advice to the architect for the project, meet with and discuss the preliminary plans with DOP officers and prepare an Environmental Assessment (EA) report for submission to the Department of Planning that addresses the DGR's for both the Concept plan and for Stage 1 of the development. We note that following our discussions, we would not be involved in briefing of the sub-consultants (as this has been undertaken by you) or any public consultation (as there has been sufficient public consultation previously."
38The contract between the appellant and the respondent was entered into on or about 31 July 2009.
39Work progressed thereafter, but not without disharmony. In an email of 22 October 2009, to the appellant, Mr Swan said:
"All this argument has distracted Lynn and I from the important task of finalising the plans and EA. The late engagement of the sub-consultants has, as previously advised, also impacted on the time line e.g. the landscape architect has still not provided us with a scheme.
We require signoff of the scheme by Close of Business tomorrow or it will delay the EA final lodgement date and incur prolongation costs."
40Ms Sheridan eventually lodged an environmental assessment with the Department of Planning in December 2009. It was a very substantial document. It was submitted by Ms Sheridan's firm on the appellant's behalf.
41The Department responded by letter dated 23 March 2010 which said, in part:
"The Department has reviewed the EA for the project and is not satisfied that it adequately addresses the Director-General's Environmental Assessment Requirements (DGRs) issued on 11 February 2009.
I understand that Departmental Officers have had numerous discussions with yourself and your planning consultants, highlighting issues that require to be addressed prior to any public exhibition.
It is therefore requested that your EA be amended and revised (as detailed in Attachments 1 & 2) and a copy be re-submitted to the Department for review of adequacy."
42Attachments 1 and 2 dealt with numerous matters, including the need for detailed landscape plans, an Aboriginal archaeology assessment, a quantity surveyor's certificate, an updated contamination report, an access report, a plan concerning the rail corridor and a community consultation strategy.
43On 24 March 2010, Ms Sheridan sent the appellant a short email about co-ordination of "the various tasks" emerging from the Department's letter. She said that she had discussed this with Mr Swan. On 31 March 2010, Ms Sheridan asked the appellant by email whether he was "ok with the tasks I've assigned to you" and sought "the timeframe to complete these tasks when you have spoken to the relevant consultants".
44On 1 April 2010, the respondent (through Mr Redman) emailed Ms Sheridan (with a copy to the appellant) to outline the inputs of the respondent foreseen as necessary to provide the "additional information" required by the Department. A meeting with Department officers was suggested to clarify "the full scope of this information". On 9 April 2010, Ms Sheridan, Mr Swan and Mr Cox (also of the respondent) met with a departmental officer, Mr Smith. Minutes of the meeting identify fourteen matters requiring attention in the preparation of an "amended submission". A copy of the minutes was sent to the appellant by Mr Swan under cover of a letter dated 14 April 2010 which outlined additional work to be done by the respondent.
45A meeting with the Director-General of the Department (Mr Haddad) took place on 23 April 2010. Present were Mr Wilson of the Department, the appellant and his then solicitor (Mr Whitfield). Neither Ms Sheridan nor any representative of the respondent was present. The meeting was arranged by the appellant. Notes taken by the appellant recorded, among other things, that:
(i)Mr Wilson said it was a 'merit based' assessment and that is why they wanted stronger argument; and
(ii) Mr Wilson "was scathing about the quality of the presentation and described the planner's assembly of the information as 'lazy'".
46On 29 April 2010, the appellant emailed Ms Sheridan (with a copy to Mr Swan) complaining that she had not been able to give him "a tip-off in January as to what extra work might be required instead of waiting until the end of March", noting that he had "relied on your [ie, Ms Sheridan's] assurances that you had prior experience with Part 3a and Andrew Smith"; also that "75% of TOA submissions are successful according to the DOP published information".
47On 5 May 2010, Mr Swan wrote to the appellant referring to the attachments to the letter of 23 March 2010 (which he described as "the Test of Adequacy response") and asking that the appellant "as a matter of urgency" finalise "the engagement of all the necessary consultants" some of which were then mentioned. The letter continued:
"Lynne has advised that she cannot complete the EA report until all this information is at hand.
As it stands, the project is being unnecessarily delayed because the required information is not available."
48The appellant emailed Mr Cox of the respondent (with copies to Ms Sheridan, Mr Swan and Mr Whitfield)) complaining that none of "Dale, Stephen, Lynn, Chris and Andrew" had any intention of "considering the legal rights and obligations involved". He also complained of delay and said:
"The delay is due to the failure of my consultants who have been engaged at a cost of $440,000 to pass a TOA. DOP publishes the fact that 75% of TOAs are passed. My written and verbal instructions have been largely ignored."
49On 6 May 2010, Mr Swan wrote to the appellant in response to the email of complaint from the appellant. The letter tendered advice of various kinds on the best way forward as Mr Swan saw it. He confirmed that the respondent's role was to "assist you in the preparation of documents for an Environmental Assessment submission to the Department of Planninjg (DOP)"; and
"Our aim remains to present a scheme to the DOP that is able to be approved."
50After denying an allegation by the appellant that the respondent had caused delay, Mr Swan said:
"It is not a matter of passing or failing the Test of Adequacy. The TOA is for the Department to review the documents and request more clarification/information if required before advertising. That is exactly what they have done."
51Mr Whitfield, the appellant's solicitor, wrote to Mr Wilson of the Department on 12 May 2010. He thanked Mr Wilson for "viewing the presentation by Ancher Mortlock about density and height which addresses the principal issue raised in Attachment 1". Mr Whitfield asked that Mr Wilson "give consideration as to how the following exemptions from Attachment 2 can be dealt with as soon as practicable to enable us to finalise our answers". Five particular items were then mentioned. The references to "Attachment 1" and "Attachment 2" are clearly references to the two attachments to the Department's 23 March 2010 letter.
52On 27 May 2010, Mr Swan wrote to the appellant expressing concern about continuing delay "in submitting the Environmental Assessment document to the Department of Planning (DoP)". He said:
"The submission could have been made over a month ago if the matter in the Test of Adequacy [ToA] had been addressed and the necessary consultants engaged promptly."
53The appellant made a strong complaint by email of 27 May 2010 to Mr Cox:
"I entered into $440,000 worth of contracts to pass a TOA. The DOP took months longer to assess it and neither they nor my consultants tipped me off about the forthcoming result. Now everyone wants extra fees because they collectively stuffed up."
54Mr Swan replied on 28 May 2010:
"Your comment regarding the consultants not 'tipping you off' is totally inaccurate and misleading. The consultants did not 'stuff up' as you say. On the contrary, you did by not engaging all the necessary and appropriate consultants in a timely manner to carry out the required scope of work.
We have, from the inception of the project, continually written to you about this very problem. You chose to go against the advice of the architect/planner and not provide contamination, aboriginal/archaeology, and other items specifically required by the DGR's."
55Further documents were in due course submitted to the Department and, on 25 October 2010, the respondent reported to the appellant by letter that the Department had "now confirmed the adequacy of the Environmental Assessment (EA) submission to be placed on public exhibition" but that "further minor additional information" had been requested.
56This was confirmed by a letter dated 10 November 2010 from the Department addressed to the appellant which began:
"The Department has reviewed the revised Environmental Assessment (EA) for the above project and considers it to be adequate for public exhibition provided that the additional information as highlighted in Attachment 1 is submitted prior to the EA being placed on public exhibition."
57On the same day, Ms Sheridan emailed to the appellant and others "signed TOA letter from the Department, stating we are ok for public exhibition".
58On 11 November 2010, Mr Swan emailed the appellant saying that "the signed Test of Adequacy" had been received. This may be accepted as a reference to the Department's letter of 10 November 2010.
59A dispute about the respondent's fees and contractual obligations with respect to the "next phase of work" then ensued. In a letter dated 17 March 2011, the respondent stated that it had performed the work it was contracted to do; was not contractually obliged to work on the next phase of project; and gave notice of termination of the contract in accordance with clause F2.
60The appellant wrote to the respondent on 5 April 2011. He purported to give notice of termination of the contract "on the grounds of AMW's incapacity and failure to perform as partly set out in the Director-General's letter to me of which AMW has a copy". The respondent's solicitors wrote to the appellant on 8 April 2011 disputing the effectiveness of the appellant's purported termination "as the Contract had already been effectively terminated by notice from our client dated 17 March last."
61On 19 April 2011, Mr Wilson of the Department wrote to the appellant referring to the fact that the application had been placed on public exhibition. Mr Wilson noted that "a copy of all submissions received have been forwarded for consideration". Mr Wilson said that the Department had identified a number of issues relating to "height and building layout, environmental constraints, residential amenity, traffic generation and carparking". These were listed in Schedule 1 of two pages headed "Key issues". Mr Wilson also drew attention to "additional information" required, as set out in Schedule 2 of about a page and a half.
