A standard of review that asks whether evidence, viewed in the light most favorable to the prosecution, would permit a rational trier of fact to find every essential element of the offense beyond a reasonable doubt. The inquiry protects due process by ensuring no conviction rests on legally insufficient proof. A party may raise the issue on appeal even without having preserved it through post-verdict motions.
Sabrina Shah sued Sterling Manufacturing for breach of contract after a bench trial. The district court entered judgment for Sabrina based on its factual findings. Sterling appealed, arguing the evidence could not support those findings.

The government sought to introduce Sebastian Santos's earlier uncharged transfers to show intent in the current embezzlement prosecution.

In civil cases a party that fails to file a renewed motion under Rule 50(b) is barred on appeal from arguing the evidence was legally insufficient. In criminal cases the defendant may raise insufficiency for the first time on appeal because it implicates due process.
