Facts
Cooper agreed to lease a salmon fishery from Phibbs. Unknown to both, Cooper already owned it in equity.

Could the agreement be set aside for mistake?
Held
Yes. The House of Lords set it aside on terms, as both parties were mistaken about the ownership of the fishery.
Principle
Equity may set aside an agreement made under a common mistake as to private rights, on terms.
Why it matters
It is the classic case on for mistake, though English courts now limit equitable relief for common mistake.
