When (a) one of two or more joinable offenses of the kind\nspecified in subdivision one is charged in an accusatory instrument, and\n(b) another is not charged therein, or in any other accusatory\ninstrument filed in the same court, despite possession by the people of\nevidence legally sufficient to support a conviction of the defendant for\nsuch uncharged offense, and (c) either a trial of the existing\naccusatory instrument is commenced or the action thereon is disposed of\nby a plea of guilty, any subsequent prosecution for the uncharged\noffense is thereby barred.\n 3.
