Rule 605. Mistrial.

 (A)  Motions to withdraw a juror are abolished.

 (B)  When an event prejudicial to the defendant occurs during trial only the defendant may move for a mistrial; the motion shall be made when the event is disclosed. Otherwise, the trial judge may declare a mistrial only for reasons of manifest necessity.

   This rule replaces the practice of moving for the withdrawal of a juror.

   Examples of ‘‘manifest necessity’’ can be found in Commonwealth v. Stewart, 317 A.2d 616 (Pa. 1974); Commonwealth v. Brown, 301 A.2d 876 (Pa. 1973); United States ex rel. Russo v. Superior Court of New Jersey, Law Division, Passaic County, 483 F.2d 7 (3rd Cir. 1973), cert. denied, 414 U.S. 1023 (1973); United States v. Tinney, 473 F.2d 1085 (3rd Cir. 1973), cert. denied, 412 U.S. 928 (1973); United States v. Jorn, 440 U.S. 470 (1971); and United States v. Perez, 9 Wheat. 579 (1824); see also Illinois v. Somerville, 410 U.S. 458 (1973).

   See Rule 587(b) for the procedures when a motion to dismiss on double jeopardy grounds is filed.
