“In my judgment, these cases show that, wherever there is a voluntary transaction by which one party intends to confer a bounty on another, the deed will be set aside if the court is satisfied that the disponor did not intend the transaction to have the effect which it did. It will be set aside for mistake whether the mistake is a mistake of law or of fact, so long as the mistake is as to the effect of the transaction itself and not merely as to its consequences or the advantages to be gained by entering into it.”
“23. His Lordship's distinction between the effect of the transaction and its consequences or advantages has proved a difficult one to grasp. Davis J in Anker-Petersen v Christensen[2002] WTLR 313 , Lloyd LJ in Sieff v Fox[2005] 1 WLR 3811 and Mann J in Wolff v Wolff[2004] STC 1633 have all expressed that difficulty. The principal debate has been whether a mistake by an individual (as opposed to a trustee) about the fiscal consequences of entering into a transaction counts as a mistake about the effect of the transaction or a mistake about its consequences or advantages. I do not need to resolve this debate. Mr Grierson said that a mistake about the fiscal consequences of entering into a transaction was enough to bring the jurisdiction into play even in a case involving an individual rather than trustees. But even if he is right, I do not think that this helps him on the facts of this case. The initial transfer of the shares into the discretionary trust was a chargeable transfer for the purposes of inheritance tax and was intended to be a chargeable transfer. So there was no mistake about its fiscal consequences. The grant of the deferred lease was intended to be a potentially exempt transfer. That is precisely what it was. There was no mistake about the immediate tax consequences of the grant. Similarly the intended effect of the transaction consisting of the transfer of Mr Griffiths's reversionary interest in the shares was intended to be a potentially exempt transfer for the purposes of inheritance tax. Again that is precisely what it was. There was no mistake about the immediate tax consequences of that transfer either. What was unexpected was Mr Griffiths's subsequent death just over a year later. Mr Grierson accepted, as I understood it, that if Mr Griffiths had been a hale and hearty young man and had entered into all the relevant transactions but fallen under a bus the following week, his executors would not have been able to ask the court to set aside the transactions on the ground of a mistake. I think that is right. The operative mistake must, in my judgment, be a mistake which existed at the time when the transaction was entered into. The mere falsification of expectations entertained at the date of the transaction is not, in my judgment, enough.”
“In a case where it is an individual disposing of his own property, it seems to me that the higher test applies. Thus the claimants must show that if Mr Griffiths had been aware of the true facts he would not have acted as he did. I should add that I do not consider that it is necessary for the claimants to show what Mr Griffiths would have done if he had not made the mistake. It is sufficient for them to show that he would not have done what he in fact did. I say this because the evidence suggests that Mr Griffiths would have done nothing and simply left his widow to inherit under his will. But that course of action would only have been effective if (as actually turned out) Mrs Griffiths survived her husband. In the course of argument Mr Grierson preferred the suggestion that Mr Griffiths would have made lifetime gifts to his wife leaving it to her to enter into the transactions recommended by the tax consultants. The difficulty with this suggestion was that there was no evidence to support it. But it shows that there were at least two possibilities available to Mr Griffiths had he not entered into the transactions into which he did in fact enter.”
