How it applies
Common Examples

Deed in Lieu Under Pressure
Usman Uddin, facing imminent foreclosure on his commercial building, transferred title to Upstream Petroleum after the lender threatened immediate acceleration and public sale. The lender had previously misapplied payments and reported false delinquencies that damaged Usman's credit. A court later examined the transfer for duress or unfairness because the lender's prior misconduct magnified the coercive effect of its demand.
Pendent Unfair Competition Claim
Ultimate Solutions sued Ultra Precision in federal court for copyright infringement over copied climate maps and added a state-law unfair competition claim arising from the same submissions to a state agency. The federal court exercised pendent jurisdiction over the state claim because both causes of action shared the same nucleus of operative facts.

Duplicate Document Admission
Uriah Urban offered a photocopy of a signed lease to prove its terms after the original was lost. The opposing party raised no genuine question about the original's authenticity and presented no circumstances showing that admission of the duplicate would be unfair. The court therefore admitted the duplicate to the same extent as the original.
Prior Unfair Dealing in Modification
Usha Upton's bank misapplied loan payments and falsely reported her as delinquent. When the bank later threatened immediate acceleration unless she signed a modification adding a personal guarantee, the prior misconduct significantly increased the threat's coercive effect. A court treated the threat as improper because the resulting exchange was not on fair terms.
Uncharged Misconduct Under 404(b)
The prosecution sought to introduce evidence that Uma Upadhyay had previously altered shipping records in a similar transaction. The court admitted the evidence after finding sufficient proof from which a jury could reasonably conclude the prior act occurred and after determining under Rule 403 that its probative value on intent was not substantially outweighed by the danger of unfair prejudice.
Exclusion of Prior Conviction
In a felon-in-possession prosecution, the government offered the full record of Ursula Ung's prior conviction after she offered to stipulate to the status element. The court excluded the detailed record because the name and nature of the conviction carried a risk of unfair prejudice that substantially outweighed its probative value when the only disputed fact was the defendant's status as a felon.
Common questions
Frequently Asked
3
When does prior unfair dealing render a threat improper for purposes of economic duress?+
A threat is improper when the resulting exchange is not on fair terms and the effectiveness of the threat is significantly increased by the threatening party's prior unfair dealing. Courts examine whether the prior misconduct placed the victim in a weaker bargaining position that the threat then exploited.
Supporting sources
What standard governs exclusion of evidence because it is unfairly prejudicial?+
Under Rule 403 a court may exclude relevant evidence if its probative value is substantially outweighed by a danger of unfair prejudice. The inquiry focuses on whether the evidence creates a risk that the jury will decide on an improper basis rather than on the evidence's legitimate probative force.
Supporting sources
Does a deed in lieu of foreclosure receive scrutiny for unfairness?+
Yes. Courts examine deeds in lieu of foreclosure for duress or unfairness because the transaction must be voluntary and supported by consideration. Prior misconduct by the mortgagee that magnifies the mortgagor's vulnerability can render the transfer subject to later avoidance.
