Section 109 - When prosecution barred by former prosecution for the same offenseWhen a prosecution is for a violation of the same provision of the statutes and is based upon the same facts as a former prosecution, it is barred by such former prosecution under the following circumstances:
(1) The former prosecution resulted in an acquittal. There is an acquittal if the prosecution resulted in a finding of not guilty by the trier of fact or in a determination that there was insufficient evidence to warrant a conviction. A finding of guilty of a lesser included offense is an acquittal of the greater inclusive offense, although the conviction is subsequently set aside.(2) The former prosecution was terminated, after the indictment had been found, by a final order or judgment for the defendant, which has not been set aside, reversed, or vacated and which necessarily required a determination inconsistent with a fact or a legal proposition that must be established for conviction of the offense.(3) The former prosecution resulted in a conviction. There is a conviction if the prosecution resulted in a judgment of conviction which has not been reversed or vacated, a verdict of guilty which has not been set aside and which is capable of supporting a judgment, or a plea of guilty accepted by the court. In the latter two cases failure to enter judgment must be for a reason other than a motion of the defendant.(4) The former prosecution was improperly terminated after the first witness was sworn but before a verdict, or after a plea of guilty was accepted by the court.1972, Dec. 6, P.L. 1482, No. 334, § 1, effective 6/6/1973.
