Common questions
Frequently Asked
3
When does a variance between proof and pleadings require formal amendment of the complaint?+
A variance requires formal amendment only when the opposing party objects and the court finds prejudice. Under the federal rules, if evidence on an unpleaded issue is introduced without objection, the court treats the pleadings as amended by implied consent.
Supporting sources
How does harmless-error review apply to variances in criminal cases?+
Any variance that does not affect substantial rights must be disregarded on appeal. The government bears the burden to show the variance had no reasonable probability of influencing the verdict.
Supporting sources
Does failure to object at trial waive a later claim of variance?+
Yes. When a party presents evidence outside the pleadings and the opponent remains silent, the silence constitutes implied consent to amendment of the pleadings under Rule 15(b)(2).
