18 APPENDIX U.S.C. § 14
NOTES OF ADVISORY COMMITTEE ON RULES-1944 This rule is a restatement of existing law under which severance and other similar relief is entirely in the discretion of the court, 18 U.S.C. [former] 557 (Indictments and presentments; joinder of charges); Pointer v. United States, 151 U.S. 396; Pierce v. United States, 160 U.S. 355; United States v. Ball, 163 U.S. 662, 673; Stilson v. United States, 250 U.S. 583.
NOTES OF ADVISORY COMMITTEE ON RULES-1966 AMENDMENTA defendant may be prejudiced by the admission in evidence against a co-defendant of a statement or confession made by that co-defendant. This prejudice cannot be dispelled by cross-examination if the co-defendant does not take the stand. Limiting instructions to the jury may not in fact erase the prejudice. While the question whether to grant a severance is generally left within the discretion of the trial court, recent Fifth Circuit cases have found sufficient prejudice involved to make denial of a motion for severance reversible error. See Schaffer v. United States, 221 F.2d 17 (5th Cir. 1955); Barton v. United States, 263 F.2d 894 (5th Cir. 1959). It has even been suggested that when the confession of the co-defendant comes as a surprise at the trial, it may be error to deny a motion or a mistrial. See Belvin v. United States, 273 F.2d 583 (5th Cir. 1960).The purpose of the amendment is to provide a procedure whereby the issue of possible prejudice can be resolved on the motion for severance. The judge may direct the disclosure of the confessions or statements of the defendants to him for in camera inspection as an aid to determining whether the possible prejudice justifies ordering separate trials. Cf. note, Joint and Single Trials Under Rules 8 and 14 of the Federal Rules of Criminal Procedure, 74 Yale L.J. 551, 565 (1965).
COMMITTEE NOTES ON RULES-2002 AMENDMENT The language of Rule 14 has been amended as part of the general restyling of the Criminal Rules to make them more easily understood and to make style and terminology consistent throughout the rules. These changes are intended to be stylistic only.The reference to a defendant's "confession" in the last sentence of the current rule has been deleted. The Committee believed that the reference to the "defendant's statements" in the amended rule would fairly embrace any confessions or admissions by a defendant.
