Bahr v Nicolay (No 2) (1988) 164 CLR 604
The Bahrs sold land to Nicolay under a contract that included a clause giving the Bahrs an option to repurchase the land. Nicolay on-sold the land to the Thompsons, who took their transfer with express notice of the repurchase clause. The Thomnsons subsequently refused to honour the option, relying on the indefeasibility provisions of the Transfer of Land Act 1893 (WA).
1. Whether the Thompsons, as registered proprietors, could rely on indefeasibility under the Torrens system to defeat the Bahrs' equitable right to repurchase. 2. Whether a constructive trust or personal equity arising from the Thompsons' express notice of the option could operate as an in personam exception to indefeasibility.
The High Court held unanimously that the Bahrs were entitled to enforce the repurchase option against the Thompsons, finding (by different reasoning among the justices) that indefeasibility did not protect a registered proprietor who took title subject to a personal equity or constructive trust arising from their own conduct or undertaking.
Indefeasibility of title under the Torrens system does not bar an in personam claim against a registered proprietor where that proprietor, at the time of registration, had expressly undertaken or was otherwise bound by an obligation — whether characterised as a constructive trust or personal equity — that would make it unconscionable for them to rely on their registered title to defeat that obligation.
Mason CJ and Dawson J expressed the view that the Thompsons took subject to a constructive trust arising from their express undertaking to honour the option, while Wilson and Toohey JJ preferred to characterise the entitlement as a pre-existing equitable interest that survived registration because the Thompsons were not bona fide purchasers for value without notice in the relevant sense. Both streams of reasoning affirmed that the in personam exception to indefeasibility is available where unconscionable conduct by the registered proprietor is established, but the precise doctrinal basis for that exception remains a matter of ongoing debate.
Bahr v Nicolay (No 2) is the leading High Court authority confirming that the in personam (personal equity) exception to Torrens indefeasibility is part of Australian law, and it continues to define the boundaries within which constructive trusts and personal equities may be enforced against registered proprietors.
