Idaho R. Crim. P. 14
As amended through March 12, 2024
If it appears that a defendant or the state is prejudiced by a joinder of offenses or of defendants in a complaint, indictment or information, the court may order the state to elect between counts, grant separate trials of counts, grant a severance of defendants, or provide whatever other relief justice requires. In ruling on a motion by a defendant for severance the court may order the attorney for the state to deliver to the court for inspection in camera any statements or confessions made by the defendants that the state intends to introduce in evidence at the trial.
