To appropriately preserve an issue for appeal is frankly confusing to many attorneys due to differing rules depending on the issue or procedural posture (presumably why appellate attorneys are more commonly used during trial). On May 25th, the US Supreme Court handed down Dupree v. Younger, 598 U.S. __ (2023) clarifying preservation requirements from denied summary judgment orders. When a federal court denies summary judgment on sufficiency of evidence grounds, a party must raise the argument again post-trial to preserve it for appeal as per the Court’s prior ruling in Ortiz v. Jordan, 562 U.S. 180 (2011). When a court denies summary judgment on a purely legal issue, the Court unanimously held that the issue is preserved in an appeal from a final judgment without having to raise it again post-trial. The Supreme Court distinguished this from their prior rule in Ortiz by explaining that sufficiency or factual issues which were previously denied at summary judgment must be evaluated based on the totality of the evidence adduced at trial. A purely legal issue decided on summary judgment is not changed by factual evidence at trial.
