## Facts

- Melvin T. Smith was tried in Massachusetts on multiple charges arising from a shooting, including unlawful possession of a firearm.
- After the prosecution rested, Smith moved for a required finding of not guilty on the firearm count under Massachusetts Rule of Criminal Procedure 25(a), arguing the evidence was legally insufficient.
- The trial judge allowed the motion, ruling there was no evidence satisfying the statutory requirement that the firearm’s barrel was shorter than 16 inches.
- The trial proceeded on the remaining counts.
- Before closing arguments, the prosecution argued that testimony describing the weapon as a “pistol” or “revolver” was sufficient to prove the barrel-length element under Massachusetts precedent.
- The judge reversed the earlier not-guilty ruling and submitted the firearm count to the jury.
- The jury convicted Smith on all counts, including the firearm charge.
- The Massachusetts Appeals Court affirmed, concluding there was no Double Jeopardy violation because the judge’s action occurred within the same trial.
- The U.S. Supreme Court granted review.

## Issues

1. Whether the Double Jeopardy Clause is violated when a trial judge grants a midtrial motion for a required finding of not guilty for insufficient evidence, then later reverses that ruling in the same trial and submits the count to the jury.
2. Whether a Rule 25(a) required finding of not guilty based on evidentiary insufficiency is an “acquittal” for double jeopardy purposes.

## Decision

- The Supreme Court reversed, holding 5–4 that the Double Jeopardy Clause barred reinstatement of the firearm count.
- The trial judge’s Rule 25(a) ruling was an acquittal because it assessed the prosecution’s evidence and found it legally insufficient on an element of the offense.
- After that acquittal, submitting the firearm count to the jury subjected Smith to further factfinding on guilt or innocence, which the Double Jeopardy Clause prohibits.
- The fact that the judge reversed course within the same trial did not avoid the constitutional bar.
- Although a State may be able to provide a mechanism allowing reconsideration of a midtrial insufficiency ruling, Massachusetts had not clearly established such a procedure applicable to a Rule 25(a) not-guilty finding.

## Legal Principles

- A ruling is an acquittal for double jeopardy purposes when it resolves, correctly or not, an element of the charged offense in the defendant’s favor by determining the evidence is legally insufficient.
- Once a defendant is acquitted on a count, the Double Jeopardy Clause bars further proceedings on that count that require factfinding as to guilt or innocence, including submission of the count to the jury.
- A State’s label for a trial court ruling does not control whether it is an acquittal under the Double Jeopardy Clause.
- If a State seeks to permit reconsideration of a midtrial determination of evidentiary insufficiency, it must do so through a clearly established rule or statute; absent that, the acquittal is final for double jeopardy purposes.

## Conclusion

The Court held that a midtrial not-guilty ruling based on insufficient evidence is an acquittal that terminates jeopardy on that count, and the Constitution prevents the trial judge from later reinstating the charge and sending it to the jury without a clearly authorized state reconsideration procedure.
