Keogh v Rush

The case of *Keogh v Rush* concerned a dispute between the estate of a deceased life tenant and the remaindermen of a property. The life tenant had discharged a mortgage over the property and subsequently survived for 30 years before passing away. During this period, the property's value significantly increased. The remaindermen offered to reimburse the life tenant's estate for the capital amount of the discharged mortgage plus applicable interest, but the estate sought a share of the increase in the property's value. The matter was heard by Mason P, Heydon JA, and Young CJ in Eq.

The central legal issue before the court was whether, in equity, the estate of a life tenant who discharges a mortgage over a property is entitled to a share of any increase in the property's value that occurs after the discharge, even when the remaindermen offer to reimburse the capital and interest.

The court reasoned that the life tenant's act of discharging the mortgage was a voluntary act, and there was no equitable basis to award the life tenant's estate a share of the subsequent increase in the property's value. The court applied principles of equity concerning the rights of life tenants and remaindermen, concluding that the remaindermen's offer to reimburse the capital and interest was sufficient to satisfy any equitable claims. The court held that the life tenant's estate was not entitled to participate in the capital appreciation of the property.

The appeal was allowed.
