"94 It follows that transactions involved in an abusive practice must be redefined so as to re-establish the situation that would have prevailed in the absence of the transactions constituting that abusive practice. 95 In that regard, the tax authorities are entitled to demand, with retroactive effect, repayment of the amounts deducted in relation to each transaction whenever they find that the right to deduct has been exercised abusively … 96 However, they must also subtract therefrom any tax charged on an output transaction for which the taxable person was artificially liable under a scheme for reduction of the tax burden and, if appropriate, they must reimburse any excess."
"[67] Mr Cordara [counsel for the taxpayer] submits that it is of the essence of an assessment that it relates to a particular period. In my judgment, while this might be so in the generality of cases … it is necessary to look to see why the Commissioners included any item for a different period. Mr Cordara submits that there was in fact a very fundamental change in the characterisation of the underlying transactions. But we are told that the reason why the assessments as altered contained input tax and output tax relating to different periods was fortuitous. The fact was that some items were only claimed a month late. Nonetheless, they related to the same transactions as the original assessment. By that, as I understand it, he means that all the transactions formed part of the same group exit scheme as I have described above. [68] Mr Cordara has not disputed the factual basis of the explanation given to us. His position is that he takes a different view of the effect of that explanation. He says that it is not a fortuitous but a radical change. However, I prefer the submission of Mr Pleming [counsel for the Commissioners] that these circumstances are permissible because the tax in question relates to the same series of transactions as are included in the original assessment. I do not consider that their inclusion would be contrary to the principle of fairness imposed on the Commissioners by public law. If the taxpayer is entitled to additional input tax in respect of a series of transactions, he should bear the burden of additional output tax that should have been borne on that series of transactions."
