Factual and Procedural Background
The late Mr Griffiths, born in 1929, had amassed significant assets including a half share in the matrimonial home at 25 Rothesay Road and a valuable shareholding in Company A, which owned investment properties. In January 2003, aged 73, Mr Griffiths and his wife sought tax planning advice from consultants aiming to mitigate inheritance tax liabilities through potentially exempt transfers and the creation of trusts and deferred leases. Following recommendations, Mr Griffiths transferred shares into a discretionary trust in April 2003 and, jointly with his wife, granted a deferred lease of their home. In February 2004, he transferred his reversionary interest in the shares to trustees of a family trust.
Mr Griffiths was diagnosed with lung cancer in autumn 2004 and died in April 2005, less than three years after the transfers, making the transfers chargeable for inheritance tax exceeding £1 million. His executors sought to set aside the transfers on the basis that Mr Griffiths made them under a mistake regarding his life expectancy, which was shorter than he believed at the time. HM Revenue & Customs declined to intervene, and the court heard no adversarial arguments.
Legal Issues Presented
- Whether the voluntary transfers made by Mr Griffiths can be set aside on the ground of mistake under equitable jurisdiction.
- The nature and scope of the mistake required to set aside a voluntary transaction.
- Whether the transfers were void or voidable and the consequences of that distinction for inheritance tax repayment and interest.

Court's Reasoning and Analysis
The court examined the facts concerning Mr Griffiths' health and the timing of his transfers. Medical evidence established that Mr Griffiths did not have lung cancer in April 2003, and thus no operative mistake existed at that time regarding his health. The court found no sufficient evidence that Mr Griffiths made a relevant mistake about his life expectancy in April 2003 or that he would have acted differently had he known of a reduced expectancy.
Regarding the deferred lease jointly granted with Mrs Griffiths, the court declined to set it aside because Mrs Griffiths had not applied for relief and no evidence indicated she made any mistake.
In contrast, the February 2004 transfer of the reversionary interest occurred when Mr Griffiths was suffering from lung cancer but unaware of it, constituting a mistake about an existing fact. The court found that had Mr Griffiths known the true state of his health, he would not have made the transfer. This mistake was serious enough to engage the equitable jurisdiction to set aside the transaction.
The court further analyzed whether the transaction was void or voidable, concluding it was voidable. The equitable jurisdiction is discretionary and relief is granted where it is unjust for the donees to retain the gift, especially where the donor suffers an unintended tax liability. The court exercised discretion to set aside the assignment of the reversionary interest.
Holding and Implications
The court's final decision is to set aside the assignment of the reversionary interest in the shares made in February 2004 on the basis that it was entered into under a serious operative mistake as to Mr Griffiths' state of health.
The earlier transfers made in April 2003, including the discretionary trust of shares and the deferred lease, are not set aside as no operative mistake was found at that time.
The assignment being voidable rather than void means that the executors are entitled to interest on overpaid inheritance tax from the date of payment, which has financial consequences for the parties. No broader legal precedent beyond the application of established equitable principles was created by this decision.
