Common Examples

Untimely Objections Waived
Dominic Drake served interrogatories on Dover Bank seeking loan records. The bank missed the thirty-day deadline and later filed generalized objections claiming privilege. The court treated the objections as waived because the bank failed to state specific grounds timely and offered no good cause for the delay.
No Excuse for Homicide
Diane Dawson shot Devon Drake during a robbery. No doctrine excused the killing or reduced it to manslaughter. The prosecution proved Dawson acted with intent to kill, establishing malice aforethought and supporting a murder conviction.
Late Notice Excused
Dylan Duffy sought to introduce a witness statement under the residual exception. He gave written notice of the statement and declarant only two days before trial. The court excused the delay for good cause after finding the opponent had a fair opportunity to prepare.

Frequently Asked
4
Who bears the burden of proof on defenses of excuse?+
The defendant must produce evidence supporting the defense. Once that burden is met, the prosecution must disprove the defense beyond a reasonable doubt in most jurisdictions.
How do excuses differ from justifications?+
Excuses admit the act was wrongful but claim the actor was not culpable due to circumstances such as mental illness or entrapment. Justifications assert the act itself was not wrongful under the circumstances.
Can procedural failures be excused for good cause?+
Yes. Courts may excuse untimely or nonspecific objections to discovery or evidence when the party shows good cause, such as exceptional circumstances preventing timely compliance.
Does impossibility excuse contract performance?+
Yes. When a basic assumption of the contract, such as the continued existence of a specific thing, becomes impossible without fault, performance is excused under the doctrine of impossibility.
