Does the Agreement include an oral term?
27In their amended statement of claim, the plaintiffs' plead the following in par 5A:
"There was an oral term of the Agreement that within the 12 month period after the Completion Date, Wotif would not change, nor cause GoDo to change, the operating model which had been used by GoDo in the conduct of its business or the manner in which GoDo had conducted its business, prior to the sale of the shares in GoDo."
28In the particulars to par 5A, it is pleaded that the oral term is constituted or evidenced by conversations between the plaintiffs and Robbie Cooke and David Tomlins of Wotif prior to the Agreement which was reached with Wotif to purchase from the plaintiffs all of the issued shares in the capital of GoDo. The plaintiffs submit that prior to executing the Agreement, the plaintiffs sent an email to Robbie Cooke and David Tomlins of Wotif, setting out their concerns regarding the "earn out" provisions. After sending the email, but prior to entering in the Agreement, the plaintiffs had several conversations with Robbie Cooke and David Tomlins where they had said it would be "business as usual" in relation to the operation of GoDo, or words to that effect. Neither Robbie Cooke nor David Tomlinson deny that they made these statements and in any event, in an application such as the present, I should assume the correctness of the plaintiffs' allegations in this regard.
29It is the plaintiffs' case that in breach of the term pleaded in par 5A, Wotif changed, or caused GoDo to change, the operating model which had been used by GoDo in the conduct of its business prior to the sale of its shares.
30Wotif submits that the oral term, which was said to have arisen from pre-contractual negotiations, cannot survive the entire agreement clause in the Agreement at cl 19.2.
31Clause 19.2 of the Agreement states:
"19.2 Sole Understanding
This Agreement shall constitute the sole understanding of the Parties with respect to the subject matter and replaces all other agreements with respect thereto."
32Counsel for Wotif submitted that the law is clear that such a clause will exclude an alleged oral term: Hart v MacDonald [1910] HCA 13; (1910) 10 CLR 417 at 430; Hope v RCA Photophone of Australia Pty Ltd [1937] HCA 90; (1937) 59 CLR 348 at 358, 359, 363, 365 and 368; Lewison & Hughes, The Interpretation of Contracts in Australia (2012) at [3.13]; and generally Equuscorp v Glengallen Investments Pty Ltd [2004] HCA 55; (2004) 218 CLR 471 at 483-484. Counsel also referred me to the Victorian Court of Appeal where the Court held that any dispute as to whether the parties have embodied the entirety of their agreement in writing is precluded by an entire agreement clause: Retirement Services Australia (RSA) Pty Ltd v 3143 Victoria St Doncaster Pty Ltd [2012] VSCA 134 at [106-108].
33Counsel for the plaintiffs referred me to Masterton Homes Pty Ltd v Palm Assets Pty Ltd [2009] NSWCA 234 where Campbell JA at [90] summarised the principles to apply, in determining whether a contract is entirely in writing or partly oral and partly in writing, as follows (citations omitted):
(a)When there is a document that on its face appears to be a complete contract, that provides an evidentiary basis for inferring that the document contains the whole of the express contractual terms that bind the parties.
(b)It is open to a party to prove that, even though there is a document that on its face appears to be a complete contract, the parties have agreed orally on terms additional to those contained in the writing. Conversely, it is open to a party to prove that the parties have orally agreed that a document should contain the whole of the terms agreed between them.
(c)The parol evidence rule applies only to contracts that are wholly in writing, and thus has no scope to operate until it has first been ascertained that the contract is wholly in writing.
(d)Where a contract is partly written and partly oral, the terms of the contract are to be ascertained from the whole of the circumstances as a matter of fact. Similarly, finding the terms of a wholly oral contract is a question of fact.
(e)In determining what are the terms of a contract that is partly written and partly oral, surrounding circumstances may be used as an aid to finding what the terms of the contract are. If it is possible to make a finding about what were the words the parties said to each other, the meaning of those words is ascertained in the light of the surrounding circumstances. If it is not possible to make a finding about the particular words that were used (as sometimes happens when a contract is partly written, partly oral and partly inferred from conduct) the surrounding circumstances can be looked at to find what in substance the parties agreed.
(f)A quite separate type of contractual arrangement to a contract that is partly written and partly oral is where there is a contract wholly in writing and an oral collateral contract.
34I note that this case did not concern a contract where there was an entire agreement clause.
35The defendant submitted that an express statement in a contract, which provides in clear and unambiguous terms that the written contract contains the entirety of the bargain between the parties, in respect of a particular subject matter, provides an evidentiary basis for the conclusion that in respect of the subject matter of that clause, the parties have agreed that their bargain is entirely in writing.
36In oral submissions before me, counsel for the plaintiffs submitted that the Agreement was a sale of shares agreement with an earn-out arrangement based on running the business over a period of time which would not permit a person in the position of Wotif to simply compete against the business. Wotif acquired the shares and it was the company, GoDo Pty Ltd, that was to run the business. There was no provision in the Agreement as to how the business was to be run. This was the subject matter of the oral term that the parties had agreed, that after the completion of the Agreement, Wotif would not change or cause GoDo to change the operating model which had been used by GoDo for the conduct of its business prior to the sale of the shares.
37Counsel for the plaintiffs referred me to the statement of Allsop J in Branir Pty Ltd v Owston Nominees (No 2) Pty Ltd (2001) 117 FCR 424 at [440]:
"Whilst 'entire agreement' clauses have sometimes received separate treatment as a genus, leading to an approach, as evidenced by the appellants' submissions here, that there is a rule of law individually to them, it seems to me that they only reflect the epitome of the operation of the parole evidence rule. The parties have merely expressly avowed that the totality of the contract, about the relevant subject matter, is to be found within the four corners of the document."
38Importantly his Honour uses the words "the relevant subject matter" and in that case there were separate preceding arrangements, which dealt with separate subject matters.
39It was submitted that the oral term pleaded is not inconsistent with the operative provisions of the Agreement and does not contradict them, but rather adds something for which the operative provisions did not provide, namely how GoDo was to be run during the earn-out period.
40Counsel for Wotif submitted that there was an inherent unlikelihood in commercial negotiations for the sale of an internet business to a much larger one, where there were lawyers in due diligence on both sides, that there would be a critical representation made to which there was no reference in any contract or agreement and where the same topic had been dealt with by the "cap and floor" mechanism previously addressed by Gzell J.
41In his judgment in the previous proceedings, his Honour said at [15]:
"Here is seems to me that the parties did take into account that there might be, as a result of the determination of the EBITDA of the business during the 12 month period after sale, either an increase or a decrease in the purchase price. Each party was prepared to bear the risk of what might happen within the range from the minimum to the maximum adjusted price for the shares specified in the agreement for sale: the plaintiffs that it might be at the lower end of the scale, the defendant that it might be at the upper end of the scale."
42The question is of course what is the correct construction of the expression "the subject matter" in cl 19.2 of the agreement. The defendant contends for a wider reading of the expression, saying that it cannot sensibly be said that the operation of the business during the earn-out period was outside the subject matter of the Agreement. For their part, of the plaintiffs point to the nature of the sale agreement which was in fact a sale of the shares in GoDo Pty Ltd rather than the business which it operated. They also point to the provisions of the sale agreement which clearly say nothing as to how the business will be operated during the earn-out period.
43No doubt, if one takes a commercial view of the arrangement, one would favour the defendant's argument as to what is the subject matter. However, the plaintiffs' view is one which I would not describe is unarguable and because of this, I do not think it is appropriate on a summary judgment application to strike out the pleading.
