Burks v. United States

Background

The case arose from a trial for robbing a federally insured bank with a dangerous weapon under 18 U.S.C. § 2113(d). The accused’s main defense was insanity and he presented three expert witnesses whose testimony supported his claim. The Government called two experts and several lay witnesses who challenged that defense. The trial court denied a motion for judgment of acquittal, a jury convicted, and the District Court denied a post-trial motion for a new trial. On appeal the defendant conceded the basic factual elements and limited the appeal to criminal responsibility; the Court of Appeals found the evidence insufficient and remanded for either entry of acquittal or a possible new trial after further proceedings.

Reasoning

The Supreme Court considered whether a person may be tried again when a reviewing court has reversed a conviction solely because the evidence was legally insufficient. The Court reviewed prior decisions and drew a key distinction: reversals for trial errors (procedural mistakes) can justify retrial, but a reversal that holds the government failed to prove guilt means the prosecution was given its fair chance and failed. The Court held that the Double Jeopardy Clause bars a second trial after an appellate finding of evidentiary insufficiency and that the proper remedy in such cases is entry of a judgment of acquittal. The opinion overruled earlier authority to the extent it allowed retrial when an appellate court found proof legally lacking and rejected the idea that asking for a new trial waives the right to acquittal.

Real world impact

The ruling prevents prosecutors from getting a second opportunity to add missing proof after an appellate court finds the original evidence legally insufficient. Defendants gain finality when an appellate court decides the government failed to prove guilt. The opinion does not resolve the underlying insanity question on the merits and the case was remanded for proceedings consistent with this holding.
