15 The misleading and deceptive conduct relied upon was that of Mr Cook during the critical conversation. As Black CJ said, silence that is capable of being misleading or deceptive never stands alone. In the absence of some positive duty to speak, silence can only be misleading or deceptive against a background of other facts known to both parties which make what is actually said so incomplete that it conveys a misrepresentation."
40 In the present case there is no positive duty to speak. We are here concerned with whether the facts known to the parties are such that the failure to speak and raise the doubts about the adjudication process conveys a misrepresentation. There is authority that if a party anticipates that an adjudication determination will be void; it should wait until the adjudication determination is handed down. See Paynter Dixon Constructions Pty Ltd v J F & C G Tilton Pty Ltd [2003] NSWSC 869 and Australian Remediation Services Pty Ltd v Earth Tech Engineering Pty Ltd [2005] NSWSC 362. However, these were not cases of apprehended bias which have their own special concerns to which I will refer later.
41 On 11 November 2004 for the plaintiff notified the second defendant that it relied on the payment schedule issued to the first defendant on 18 October 2004 as its adjudication response. It was at this point of time that it was suggested that the plaintiff could pursue any objection in relation to the adjudicator. It had received a response from the adjudicator stating that he believed there was no bias and it did not do so.
42 It is of course clear that there must be reliance for there to be estoppel based upon representation. I have earlier spoken of the facts which are said to constitute reliance. In section 26 of the Act there is a right to withdraw an adjudication application in certain circumstances. These relate to a situation where the adjudicator fails to accept the nomination or does not determine the application within time. Neither of these applied in the present case.
43 In these circumstances the defendant would have had great difficulty in taking steps by itself to withdraw the adjudication application and proceed with a fresh payment schedule. The provisions of s 13(5) of the Act prevent the service of more the one payment claim in respect of each reference date under the construction contract. Given the final date for making a payment claim was 28 November 2004, or at least that was the time the defendant believed it could make such claim, it might be difficult for the defendant to make such a claim. This may well depend upon the terms of the contract which is not in evidence before me.
44 Effectively there was little the defendant could do of its own volition and probably the true answer to the question of whether there was a representation by silence lies in either election or waiver.
Election
45 The common law meaning of the term "election" is discussed expansively by Jordan C J in O'Connor v S P Bray Limited 1936 36 SR (NSW) 248 at 257-63 and more succinctly by Mason J in Sargent v ASL Developments Limited (1974) 131 CLR 634. At 655 he observed:
"A person is said to have a right of election when events occur which enable him to exercise alternative and inconsistent rights, ie when he has the right to determine an estate or terminate a contract for breach of covenant or contract and the alternative right to insist on the continuation of the estate or the performance of the contract. It matters not whether the right to terminate the contract is conferred by the contract or arises at common law for fundamental breach -- in each instance the alternative right to insist on performance creates a right of election."
46 Election is concerned with the choice of a party with alternative remedies already open to him where neither of these rights or remedies may be enjoyed without the extinction of the other. See Commonwealth of Australia v Verwayen (1990) 170 CLR 394 at 408-9, 481. In the present case it is said that the plaintiff was faced with the choice of either participating in the adjudication process or, alternatively, declining to do so and going to court to prevent the adjudication process from proceeding.
47 The application to court might not succeed in setting aside the adjudication application. Plainly, it was necessary for the plaintiff to indicate to the arbitrator that it relied on the payment schedule as its adjudication response or make any further submissions for the consideration by the arbitrator. All this should have occurred on 11 November 2004. Its failure to make any submissions would mean that if it had lost its challenge in court it would not have had the benefit of those being considered by the adjudicator for the purposes of his decision. The question is whether it could have made any necessary submissions as well as proceedings with a court challenge. If the plaintiff made it plain at the time that it still maintained its concern about bias and was challenging the continuing hearing, then its submissions could be on this basis. Given the tight time structures in the Act this may be a reasonable approach on the plaintiff's part. It is thus arguable that it was not facing an either or choice and thus did not need to make an election.
48 It is, of course, important to realise that an election must be made between the two inconsistent and alternative rights. No difficulty arises where the election is made expressly but that is not the case in the present matter. Election can of course be implied from conduct. The decisions on this aspect were summarised by Story in "Equity Jurisprudence" para 1097 in the following terms:
"Upon such a subject no general rule can be laid down; but every case must be left to be decided upon its own particular circumstances rather than upon any definite abstract doctrine. Lapse of time alone is not sufficient to conclude a party, for until he is called upon to elect he may enjoy all proprietary rights over the respective properties; and before he can be called upon to elect he is entitled to have the respective values of the properties ascertained to enable him to form a correct opinion as to his rights. To conclude a party by his extra-judicial acts it is necessary to show that he knew all the facts, that the fact that he was called upon to exercise his choice was present to his mind, and that these two circumstances concurring he deliberately made his choice ... When this is ascertained affirmatively, it may be further necessary to consider, whether the party was competent to make an election; whether he can restore the other persons affected by his claim to the same situation, as if the acts had not been performed, or the acquiescence had not existed; and, whether there has been such a lapse of time as ought to preclude the court from entering upon such inquiries, upon its general doctrine of not entertaining suits upon stale demands, or after long delays."
49 Mr Christofidellis, a director of the plaintiff, gave evidence on behalf of the plaintiff. His affidavit was read but he was not cross examined upon it. Although it is abundantly plain that he knew of the circumstances of the dispute at an early stage, in the absence of any cross examination, I would be reluctant to conclude that he had deliberately made the choice.
Waiver
50 There is much debate in the authorities upon the true nature of the difference between waiver, election and estoppel. Much of the debate centres upon the relationship between these concepts and the doctrine of contract. The nature of waiver was described by J S Ewart in his book "Waiver Distributed" in these terms:
"Commencing with waiver', we may say that (if it is anything) it is (it certainly used to be) of unilateral character. The possessor of some property throws it away. The effect may be that someone else is benefited, but waiver' has no relation to benefits. A watch is thrown away, and some functionary or finder is so much the richer (if the true owner do not intervene). But the `waiver' is complete although the watch be never found, although it be flung into the ocean.
