Brandon J. Barnett a/k/a Brandon Jay Barnett a/k/a Brick v. State of Mississippi

Summary

The Mississippi Supreme Court reversed Brandon J. Barnett’s methamphetamine‑selling conviction because the trial court erred by giving jury instruction S‑3A, which improperly commented on the weight of the technical reviewer’s expert testimony. The Court held that such commentary intrudes on the jury’s exclusive role to assess credibility and weight, constituting an abuse of discretion, and remanded for a new trial.
