(a) Motion by State Before Trial. If two or more defendants are to be jointly tried and the prosecuting attorney intends to introduce at trial a statement, confession or admission of one defendant involving any other defendant, the prosecuting attorney shall move before trial on notice to all defendants for a determination by the court as to whether such portion of the statement, confession, or admission involving such other defendant can be effectively deleted therefrom. The court shall direct the specific deletions to be made, or, if it finds that effective deletions cannot practically be made, it shall order separate trials of the defendants. Upon failure of the prosecuting attorney to so move before trial, the court may refuse to admit such statement, confession or admission into evidence at trial, or take such other action as the interest of justice requires.
(b) Motion by Defendant and State. If for any other reason it appears that a defendant or the State is prejudiced by a permissible or mandatory joinder of offenses or of defendants in an indictment or accusation the court may order an election or separate trials of counts, grant a severance of defendants, or direct other appropriate relief.
(c) Time. A motion for separate trial of counts of an indictment or accusation must be made pursuant to R. 3:10-2, unless the court, for good cause shown, enlarges the time.
