Facts – Louth v Diprose

The respondent (Diprose) was a solicitor, emotionally infatuated with the appellant (Louth). Louth was a divorced woman with two children, living in financial difficulty. They met in 1981. Diprose was deeply in love, but Louth was indifferent, treating him only as a friend. Diprose lavished her with gifts, paid bills, and also school fees for her children.

Louth lived in a house owned by her brother-in-law at low rent. In 1984, Louth suggested she might lose her rented house at Tranmere due to her sister’s separation. She told Diprose she would commit suicide if forced to vacate.

Diprose, believing her, bought the house in her name for $58,000 (entirely from his funds), intending to give her security.

In 1988, after their falling out, he demanded the house be transferred to him. Louth refused.

Legal Proceedings

At Trial (King CJ, Supreme Court of South Australia): Held it would be unconscionable for Louth to retain the property; ordered transfer of house to Diprose.

On Appeal (Full Court SASC): Majority upheld the decision (Matheson J dissenting).

High Court of Australia: Louth appealed.

Issue

Was the transfer of money (used to buy the house in Louth’s name) a gift obtained through unconscionable conduct that equity should set aside?

High Court’s Judgment in Louth v Diprose

Majority (Mason CJ, Brennan, Deane, Dawson, Gaudron, McHugh JJ):

Dismissed the appeal.

Diprose was under a special disability (emotional dependence/infatuation). He was emotionally dependent on Louth, leaving him vulnerable. Louth knowingly exploited this by manufacturing a false crisis and threatening suicide. This was unconscionable conduct; she could not, in good conscience, retain the benefit.

Equity may set aside a transaction if one party is at a special disadvantage, the other party knows of and exploits it, and the result is a transaction unconscionable to enforce or retain.

Special Disadvantage is not limited to poverty, illness, or ignorance. It includes emotional dependence or infatuation, where it undermines rational judgment.

Toohey J (Dissent):

Would have allowed the appeal.

Thought Diprose acted with full knowledge and appreciation of his actions.

Outcome:

The High Court held that Louth’s manipulation of Diprose’s emotional infatuation, through false crisis and suicide threats, amounted to unconscionable conduct, making it inequitable for her to retain the house.

Legal Significance

This case expanded the scope of special disability to include emotional infatuation. It reinforced that equity intervenes not to save someone from their own foolishness, but to prevent victimisation. Diprose’s act wasn’t set aside simply because buying the house was unwise. It was set aside because Louth created a false crisis and used suicide threats, exploiting his emotional dependence.

The case illustrates how relationships of emotional dependence can give rise to equitable relief.
