Courts of Equity have never set aside gifts on the ground of the folly, imprudence, or want of foresight on the part of donors. The Courts have always repudiated any such jurisdiction. It would obviously be to encourage folly, recklessness, extravagance and vice if persons could get back property which they foolishly made away with, whether by giving it to charitable institutions or by bestowing it on less worthy objects.
Salmond J. in Brusewitz v Brown [24] spoke to the same effect:
The law in general leaves every man at liberty to make such bargains as he pleases, and to dispose of his own property as he chooses. However improvident, unreasonable, or unjust such bargains or dispositions may be, they are binding on every party to them unless he can prove affirmatively the existence of one of the recognized invalidating circumstances, such as fraud or undue influence.
His Honour then goes on to distinguish cases of undue influence:
This general principle, however, is subject to an important exception. Where there is not merely an absence or inadequacy of consideration for the transfer of property, but there also exists between the grantor and the grantee some special relation of confidence, control, domination, influence, or other form of superiority, such as to render reasonable a presumption that the transaction was procured by the grantee through some unconscientious use of his power over the grantor, the law will make that presumption, and will place on the grantee the burden of supporting the transaction by which he so benefits, and of rebutting the presumption of its invalidity. In such cases it is necessary for the grantee to prove that the suspected transaction has not its source in any improper influence over the mind or will of the grantee, or in any fraud, misrepresentation, mistake, or concealment of material facts which ought to have been disclosed by the grantee to the grantor in view of the relation between them. Unless the grantee can prove this the transaction will be set aside at the suit of the grantor or his representatives.
The same approach leads to a similar conclusion when the evidence shows unconscionable conduct on the part of a donee. Once it is proved that substantial property has been given by a donor to a donee after the donee has exploited the donor's known position of special disadvantage, an inference may be drawn that the gift is the product of the exploitation. Such an inference must arise, however, from the facts of the case; it is not a presumption which arises by operation of law. The inference may be drawn unless the donee can rely on countervailing evidence to show that the donee's exploitative conduct was not a cause of the gift. At the end of the day, however, it is for the party impeaching the gift to show that it is the product of the donee's exploitative conduct. This is the final and necessary link in the chain of proof of unconscionable conduct leading to a decree setting aside the gift [25] .
