(a) It is a bar to another prosecution for the same crime if the crime is a misdemeanor, but it is not a bar if the crime charged is a felony when a person is
(1) held to answer to the grand jury and the court dismisses the charge before the case is presented to the grand jury upon the motion of the prosecuting attorney;
(2) held to answer to the grand jury and the court dismisses the charge because the indictment is not found against the person at the next session of the grand jury; or
(3) indicted for a crime and the indictment is dismissed because the trial is not held within a reasonable period of time, there is not good cause shown for the delay, and the delay was not upon the application of the defendant or with the defendant's consent.
(b) Unless the court directs a judgment of acquittal to be entered, it is not a bar to another action for the same crime if the court orders an indictment to be discharged because the prosecuting attorney is not prepared to go to trial when the indictment is called for trial and does not show sufficient cause for postponing the trial.
