Common questions
Frequently Asked
4
When does the clearly erroneous standard apply to a trial court's findings?+
The standard applies to findings of fact made by a judge after a bench trial or on pretrial motions that present factual questions such as personal jurisdiction or amount in controversy. It does not apply to pure questions of law or to mixed questions that are primarily legal.
Supporting sources
Does a party waive the right to challenge factual findings by failing to object or request more detailed findings at trial?+
No. A party may question the sufficiency of the evidence supporting the findings on appeal whether or not it requested findings, objected to them, or moved to amend them. The rule expressly preserves that right.
Supporting sources
How does the standard treat credibility determinations based on live testimony?+

Supporting sources
What must a district court do when granting or refusing an interlocutory injunction?+
The court must state the findings and conclusions that support its action. A one-line order granting a TRO without any findings or conclusions violates this requirement and may require vacatur.
