Detailed evidence was then led through Mrs Chaplin about the file of papers and notes that was allegedly compiled. These records went back as far as 19 September 1988 presumably to give an air of authenticity and commerciality to the transaction.
There was, in addition, evidence that pointed to Mr Campbell having prepared false file notes for inclusion in his office papers. For example, it was common ground that Mr Barker accompanied Mrs Chaplin on 5 May 1989 when she called on Mr Campbell at his office and first instructed him with respect to the Teckvest agreements. Yet there was a file note of that date which referred to the conference but made no mention of Mr Barker being present and a second file note of the same date referring to a phone conversation between Mr Campbell in which he told Mr Barker of the conference and Mrs Chaplin's instructions as if Mr Barker had not been present. This note read in part:-
"Attend on Mr Barker on telephone advising him of Ellen Chaplin's instructions. He was concerned about the possible appearance of divestment of assets... We informed him that Ellen had assured us that that was not the case and it was a legitimate business transaction..."
According to the Crown case Mr Campbell suffered a lapse of memory about Mr Barker's presence at the conference when, at some later date, he concocted these false entries. It is a legitimate question to ask why Mr Campbell would have had a need to ring Mr Barker with this information if, as was the fact, Mr Barker had been present when Mrs Chaplin gave her instructions to Mr Campbell.
In addition to the exercise of allegedly preparing a false trail of documents to support a history of negotiations, the Crown alleged that Mr Campbell, also on 5 May, commenced preparing agreements relating to the sale and purchase of the computer programs. An amount of $500,000.00 was telegraphically transferred to Mr Hillsdon as part of the overall scheme. This payment was required as a deposit pursuant to the first of the agreements that Mr Campbell was preparing. Later, on 19 May, Mr Campbell sent a further $210,000.00 out of his firm's trust account to Mr Hillsdon.
It is, of course, patently clear that the evidence of Mrs Chaplin was central to the Crown case. She was trenchantly attacked by the defence. It was put to her, for example, that she was spurred on to give evidence against Mr Campbell because he and his wife had not paid her all the moneys that they owed on the purchase of the jewellery business. She admitted that she had not received all her money but denied that she was motivated out of spite.
There were areas in her evidence where, so it was claimed, her memory was deficient. She was tested about the vital meeting with Mr Campbell at his office on 5 May 1989 when, on the Crown case, Mr Barker laid out the details of the Teckvest agreements. Mrs Chaplin said that she did not remember the exact details of the conversation, only "the gist" of it. This, so it was said, made her evidence unreliable.
There is no doubt that occasions arise "when a jury proceeds to a conviction when the Crown case rests on oral testimony which is so unreliable or wanting in credibility that no jury, acting reasonably, could be satisfied of the accused's guilt to the required degree": Chidiac v The Queen (1990-1991) 171 CLR 432 at 444 per Mason CJ. It was in Chidiac's Case (supra) where members of the High Court said that an appellate court will not discharge its responsibility by finding that there was evidence sufficient to entitle the jury to convict, because a verdict may be unsafe or unsatisfactory notwithstanding that there was, as a matter of law, evidence upon which the accused could have been convicted: see Mason CJ at 445 and McHugh J at 461.
But the Crown case was not limited to the evidence of Mrs Chaplin alone; there was other evidence mostly in the form of various documents, from which corroborative support could be obtained. In addition, there were events, such as the preparation by Mr Campbell of the Teckvest agreements. Taken alone, that exercise contained no sinister overtones. But, claimed the Crown, it took on a different complexion when assessed within the whole framework of the Crown case. The Crown queried how a Canberra solicitor, with no knowledge of the base details of the computer programs, would prepare contracts involving $3.5m without detailed consultation with the vendor and the vendor's legal advisers. In such circumstances might not one have expected the vendor to have submitted a draft contract to the purchasers for their consideration and that of their advisers? The Crown also questioned whether it was normal business practice to remit a deposit of $500,000.00 before the contracts were signed.
The Crown relied heavily upon a letter from Mrs Chaplin to Mr Campbell dated 18 August 1989. It amounted, according to the Crown, to confirmation that Mr Campbell knew of an arrangement whereby the Chaplins were expecting substantial sums of money to be available to them in the United Kingdom. Although this letter did not mention Teckvest or Hillsdon by name, other correspondence confirms that it could only be referring to them. At that stage, Mrs Chaplin was still in Australia but her husband, Chris, was then in the United Kingdom. The first section of that letter read as follows:-
"Chris phoned this morning. He says that it appears that his funds are still not in the account he was expecting it to be in. He is furious and says that he has to make payment for something and has no funds to do so. As well as the fact that he still has not got access to the funds he expected to.
What I am unclear about is where is the balance of the monies after approximately $500,000 - has been taken out to convert to US400,000 - to trade with."
The reference to "trade" was acknowledged by the Crown as a reference to the fact that as part of the sham, and in order to cloak it with commercial reality, Teckvest or Mr Hillsdon would carry out some currency trading on behalf of the
Chaplins. This therefore explained the reference to the amount of $500,000.00. In fact clause 7 of each of the contracts for sale that comprised the Teckvest agreements authorised "Teckvest Limited to deposit the equivalent of AUS $250,000 into a trading account "and" to apply these funds to currency trading transactions" using the computer programs. These most unusual clauses do not stand up to scrutiny. Each contract was expressed to be a contract for the sale and purchase of computer programs. Each contract stipulated a price and a method for the payment of that price. Neither contract called upon the purchasers to place additional funds in the hands of the vendor for the purpose of trading. Rather each contract, read literally, required the vendor to apply $250,000.00 of its sale price to a trading account for the benefit of the purchaser. At best these are examples of very inadequate drafting; at the worst they are evidence of a false transaction in which documents were prepared with reckless disregard for the truth.
Mr Campbell acknowledged in cross-examination that he had received Mrs Chaplin's letter of 18 August 1989. His evidence about its significance was most unsatisfactory:-
"Well, you must have been beside yourself, Mr Campbell, when you read that?...Why would I be beside myself?
Well, things were obviously going wrong, weren't they?...Mr Chaplin obviously wanted to get hold of some funds, yes. He had a large bill apparently.
And no-one knew where the money was, it would appear?...I don't think that's correct.
