Whether a federal court of equity may enjoin a pending action at law when the defendant asserts that he was fraudulently induced to enter an unsealed contract.
Holding
No. Because fraudulent inducement was a complete defense in the pending action at law on this unsealed contract, Du Pont had an adequate legal remedy and could not obtain an injunction.
Reasoning
Equity historically could restrain a legal action when the defendant possessed an equitable defense that the law court could not entertain. The relevant question was therefore not whether equity generally has power to prevent an inequitable use of legal process, but whether Du Pont's claimed defense was unavailable in the contract action itself.
At common law, a party generally could not defend an action on a sealed instrument by alleging fraud in its inducement, except for fraud affecting the instrument's actual execution. In that setting, resort to equity to cancel or restrain enforcement of the sealed instrument could be necessary because the seal prevented the law court from considering want of consideration or inducement fraud.
But the alleged agreement here was not under seal. Fraudulent representations inducing an ordinary, unsealed contract had long been a defense at law. Du Pont could therefore present the alleged fraud directly in Gardiner's pending contract action, and the existence of that legal defense made equitable intervention unnecessary and improper.
The District Court expressly found that Andrews's statement was not merely mistaken but fraudulent. Once the representation was treated as fraudulent, it fell squarely within the established legal defense available in an action on an unsealed contract. The injunction consequently could not stand.
