Weisgram v. Marley Co.
The Supreme Court ruled that federal appeals courts can order judgment for a defendant, rather than sending a case back for a new trial, when they conclude that a plaintiff's expert testimony was wrongly admitted and the remaining evidence can't support the jury's verdict.
The decision resolves a split among federal appeals courts over how much power they have to end a case outright after knocking out unreliable expert evidence, rather than giving the plaintiff another shot at trial.
“Appellate authority to make this determination is no less when the evidence is rendered insufficient by the removal of erroneously admitted testimony than it is when the evidence, without any deletion, is insufficient.”
The Court's core holding that appeals courts can order judgment even when insufficiency results from excluding bad expert evidence.
How it got here: The trial court denied Marley's motions and entered judgment for Weisgram; the Eighth Circuit reversed, ruled the expert testimony inadmissible, and directed judgment for Marley; the Supreme Court took the case to resolve a circuit split.
The Case in Depth
What happened
Bonnie Weisgram died of carbon monoxide poisoning when fire broke out in her home. Her son sued Marley Company, the maker of an electric baseboard heater near the front door, claiming a defect in the heater caused the fire and her death. At trial he relied on three expert witnesses to prove the defect and its link to the fire, and the jury ruled in his favor.
The question before the Court
If an appeals court decides key expert testimony should never have been let in, and what's left isn't enough to support the jury's verdict, can that court simply order judgment for the losing party instead of sending the case back for a new trial?
The Court's answer
Yes — the Supreme Court held that a federal appeals court can direct that judgment be entered for the defendant, rather than remanding for a new trial, when it determines that a plaintiff's expert testimony was inadmissible and the remaining evidence isn't enough to support the jury's verdict. This power comes from the same authority appeals courts already had under Neely v. Martin K. Eby Construction Co. to order judgment when evidence was insufficient from the start, and nothing about the insufficiency arising from excluded expert testimony changes that.
The Court rejected the plaintiff's push for an "automatic remand" rule whenever insufficiency stems from evidentiary exclusion, reasoning that fairness concerns are just as strong either way, since parties always have notice and a chance to argue for a new trial. Because this case was not close and the plaintiff never identified other evidence he could have offered, the appeals court acted within its discretion.

Why it matters
Plaintiffs who build their case around expert witnesses now face real finality if an appeals court later finds that expert testimony unreliable under the Daubert standard: losing on appeal can mean the case is over, not just sent back for a redo. Defendants gain a faster path to ending weak cases, and litigants on both sides have extra incentive to vet expert evidence carefully before trial.
What changes now
The Eighth Circuit's judgment for Marley Company stands, meaning Weisgram's case is over rather than being retried. This is a final merits decision that settles a split among the federal appeals courts, giving those courts clear authority going forward to order judgment for a defendant rather than automatically remanding whenever insufficiency results from excluding unreliable expert testimony.
What this does not decide
The Court did not decide whether Weisgram's expert testimony was actually unreliable — it treated the Eighth Circuit's finding on that as settled. It also did not require appeals courts to always order judgment instead of a new trial; that choice remains a case-by-case exercise of the appellate court's discretion.
How the Court got there
The legal reasoning, step by step
- The Court looked to Federal Rule of Civil Procedure 50, which lets a trial court take a case away from the jury and enter judgment for one side when the evidence, even viewed favorably to the other side, is not legally sufficient to support a verdict.
- The Court relied on its earlier ruling in Neely v. Martin K. Eby Construction Co. (1967), which held that when a trial judge wrongly denies a motion for judgment as a matter of law, an appeals court itself has the power to order that judgment rather than only sending the case back.
- The Court explained this appellate power flows from a federal statute, 28 U.S.C. § 2106, which lets appeals courts enter whatever judgment is 'just under the circumstances,' and that using this power does not violate the constitutional right to a jury trial.
- The Court rejected the plaintiff's argument that this power should disappear specifically when the evidence becomes insufficient because the appeals court excised unreliable expert testimony, reasoning that Rule 50 asks only whether a 'legally sufficient evidentiary basis' exists, and excluded evidence contributes nothing to that basis no matter why it was excluded.
- The Court found no unfairness in denying a new trial here, since the plaintiff had notice throughout the case that his experts' reliability was under attack, had chances to argue for a new trial on appeal and in a rehearing petition, and never actually identified other evidence he could have offered.
- Because the case was not close and the plaintiff had a full and fair opportunity to make his case, the Court concluded the appeals court acted within its discretion by directing judgment for the defendant instead of remanding for a new trial.
