Commonwealth v. Mattis

In Commonwealth v. Mattis, the defendant appealed, following his stipulated bench trial convictions. The Pennsylvania Superior Court vacated the judgment of sentence and remanded, ruling that the trial court erred when it denied the defendant’s suppression motion. The Court held that the defendant’s “extraordinarily nervous behavior” did not provide a sufficient basis to warrant an investigatory detention after the primary purpose of the initial stop ended.
