Colo. Mun. Ct. R. P. 214
If it appears that a defendant or the prosecution is prejudiced by a joinder of offenses or of defendants in a complaint or summons and complaint or by such joinder for trial together, the court may order an election or separate trials of counts, grant a severance of defendants, or provide whatever other relief justice requires. Upon motion any defendant shall be granted a separate trial as of right if the court finds that the prosecution probably will present against a joint defendant evidence, other than reputation or character testimony, which would not be admissible in a separate trial of the moving defendant, and that such evidence would be prejudicial to those against whom it is not admissible. In ruling on a motion by a defendant for severance, the court may order the prosecutor to deliver to the court for inspection in camera any statements or confessions made by the defendants which the prosecution intends to introduce in evidence at the trial.
