Solle v Butcher [1950] 1 KB 671
Solle v Butcher (1950) is a foundational case in English contract law. It focusses on the principles of equitable mistake and the possibility of rescission on equitable grounds.
Solle v Butcher taught that if both parties make a fundamental mistake, equity (fairness) might allow the contract to be voided on fair terms, even when common law keeps it binding.
Facts of the Case: Solle v Butcher
Mr Charles Butcher (landlord) leased a flat in Maywood House, Beckenham, to Mr Godfrey Solle (tenant) at £250 per year. Both parties believed the Rent Acts did not apply.
In fact, the Rent Acts did apply, meaning the statutory regulated rent was capped at £140 per year, unless proper statutory notice had been served. That notice had not been served.
Solle sought repayment for the excess rent paid.
Butcher counterclaimed, arguing that, due to a common mistake, the lease should be rescinded or cancelled. Both parties made the same mistake about rent regulation.
What Did the Court Decide?
The Court of Appeal (majority) held there would be no repayment of the excess rent paid.
However, the lease could be rescinded, meaning it could be cancelled—but “on terms”—specifically, Solle could either choose to remain in the flat at the full contractual rent (£250) with proper notice served or to terminate the lease and vacate the flat.
Lord Justice Denning asserted that while the contract was valid at law, it was voidable in equity. He said that a contract can be set aside in equity if the mistake was common and fundamental (both parties were equally wrong about the effect of rent control), and the party seeking rescission was not at fault. The court could impose fair terms in rescission.
Lord Justice Denning stated as under:
“A contract is liable in equity to be set aside if the parties were under a common misapprehension … provided the misapprehension was fundamental and the party seeking to set it aside was not himself at fault.”
Legal Significance (Solle v Butcher)
This case established that while a contract may remain valid at common law, equity can render it voidable and subject to fair terms. However, this doctrine was later doubted and rejected in Great Peace Shipping Ltd v Tsavliris Salvage (2002), which restricted the scope of equitable rescission.
