“Supreme Court raises bar for setting aside trust deeds made under mistake”

Facts

Mr Pitt created a discretionary trust for his severely disabled son following a road accident settlement. Due to inadequate tax advice, the trust structure resulted in substantial inheritance tax liability that could have been avoided with proper planning.

Issues

Whether a voluntary disposition can be set aside in equity on grounds of mistake, and what test applies for determining when such relief should be granted.

Held

A voluntary disposition may be set aside for mistake, but only where the mistake is sufficiently serious that it would be unconscionable to leave the disposition uncorrected. The mistake must be causative and the consequences sufficiently grave.

Significance

This decision significantly restricts the circumstances in which trust deeds and tax planning arrangements can be unwound due to mistakes, providing greater certainty for trustees and beneficiaries.
