[This headnote is not to be read as part of the judgment]
Dr Anthony Castagna and Mr Robert Agius were charged with offences arising out of payments made by Macquarie Bank Ltd and its associated companies in exchange for the supply of Dr Castagna's services as a consultant during a period of time from 1998 to 2009. It was alleged that Dr Castagna was required to declare these payments as part of his "assessable income" for income tax purposes and that he failed to do so. Thus, the charges were that Dr Castagna and Mr Agius were members of a conspiracy to defraud or cause financial loss to the Commonwealth by concealing Dr Castagna's "assessable income", and a conspiracy to deal with money which was the proceeds of crime, being the part of the payments not declared as "assessable income".
The payments were made by Macquarie Bank and its associated companies pursuant to a series of agreements between itself, Dr Castagna, and Billbury Ltd, a company controlled by Mr Agius. The agreements provided that Billbury would supply Dr Castagna's services as a consultant in exchange for the payments from Macquarie Bank. The agreements did not provide for any payment to be made directly to Dr Castagna. The evidence showed that, at the relevant times, Macquarie Bank required all agreements with its consultants to be with companies rather than individuals. Thus, there was no suggestion that the agreements between Macquarie Bank, Dr Castagna and Billbury were "shams".
At trial, the prosecution case was that, even though the payments were made to Billbury and the agreements between Macquarie Bank, Billbury and Dr Castagna were not "shams", the payments were "ordinary income" which had been "derived" by Dr Castagna within the meaning of s 6-5(2) of the Income Tax Assessment Act 1997 (Cth), and therefore were "assessable income" which he had not but was required to declare on his income tax returns. The prosecution case invited the jury to consider the circumstances of the case as a whole to determine whether the payments to Billbury were "ordinary income" which had been "derived" by Dr Castagna.
At the conclusion of the prosecution case, Dr Castagna and Mr Agius each made an application for a directed verdict on the basis that, as a matter of law, the payments to Billbury could not be "ordinary income" which had been "derived" by Dr Castagna by reason of the terms of the agreements between Macquarie Bank, Billbury and Dr Castagna. The primary judge rejected their applications. The primary judge gave directions to the jury about how they were to approach the task of determining whether the payments to Billbury were "ordinary income" which had been "derived" by Dr Castagna which reflected the prosecution case by inviting them to consider the circumstances of the case as a whole. The jury found Dr Castagna and Mr Agius guilty of conspiracy to defraud or cause financial loss to the Commonwealth, and to deal with money which was the proceeds of crime.
Dr Castagna and Mr Agius appealed from their convictions on the grounds that the primary judge had erred in directing the jury about how they were to approach the task of determining whether the payments to Billbury were "ordinary income" which had been "derived" by Dr Castagna, relying on similar arguments which they had raised on their applications for directed verdicts. At the hearing of the appeal, the prosecution sought to uphold the convictions on the basis that it was open to the jury to hold that the payments to Billbury formed part of Dr Castagna's "assessable income" because they were held by Billbury on trust for Dr Castagna. Both counsel for Dr Castagna and counsel for Mr Agius objected to the prosecution putting its case in this way on the appeal when it had formed no part of its case at trial.
The main issues on the appeal were:
1 whether the primary judge had erred on the applications for directed verdicts and in directing the jury that, in order to determine whether the payments to Billbury were "ordinary income" which had been "derived" by Dr Castagna within the meaning of s 6-5(2), it was necessary to consider the circumstances surrounding the agreements;
2 whether it was open to the jury to find that the payments to Billbury formed part of Dr Castagna's "assessable income" because they were held by Billbury on trust for Dr Castagna; and
3 whether, in these circumstances, the court should order that Dr Castagna and Mr Agius be retried.
Whether circumstances surrounding the agreements could be considered in determining whether the payments were "ordinary income"
(i) The primary judge erred on the applications for directed verdicts and in directing the jury that, in order to determine whether the payments to Billbury were "ordinary income" which had been "derived" by Dr Castagna within the meaning of s 6-5(2), it was necessary to consider the circumstances surrounding the agreements. It would only have been relevant to do so to determine if there was some other legal relationship which affected how the agreements would be carried out. However, since no such case was put at trial, it was an error to go beyond the terms of the agreements to determine whether the payments were "ordinary income" which had been "derived" by Dr Castagna: [133]-[136] (The Court).

Whether open to the jury to find that the payments were "assessable income" because they were held on trust
(ii) It was not open to the jury to find that the payments to Billbury formed part of Dr Castagna's "assessable income" because they were held by Billbury on trust for Dr Castagna. The prosecution had not put any such case to the jury at trial. If it had, it would have been necessary for the jury to be satisfied that the settlor had the relevant intention to create the trust and that the requirements for a trust to be created had been fulfilled, which was not done. Therefore, the convictions of Dr Castagna and Mr Agius could not be supported on this basis: [175]-[179] (The Court).

Whether the Court should order a retrial
(iii) The Court declined to make an order that Dr Castagna and Mr Agius be retried. On the assumption that the case which would be put at any retrial would have been based on the allegation that Billbury held the payments from Macquarie Bank on trust for Dr Castagna, this case would have been significantly different from that put at the original trial. Even assuming that such a case would have been strong, it was not appropriate to order a retrial when the time which had elapsed since the offences occurred, the likely delay before any new trial, the age of Dr Castagna and Mr Agius, the time which had already served, and the fact that the case had not been put at the original trial were taken into account: [198]-[201] (The Court).
