Discharge of codefendant as bar.

It is an acquittal of the defendant discharged and a bar to another prosecution for the same crime when two or more persons are charged in the same indictment, and the court dismisses the indictment against a defendant (1) before that defendant has begun to present a defense and on the application of the prosecuting attorney so that the defendant may be a witness for the state; or (2) before the evidence is closed and on the application of another defendant on trial so that the discharged defendant may be a witness for a codefendant, and when, in the opinion of the court, there is not sufficient evidence to require the discharged defendant to present a defense.
