Joinder and Severance in Federal Criminal Cases: Rules 8 and 14

Joinder of Offenses in Federal Court Under Rules 8 and 14

Federal prosecutors frequently charge multiple offenses in a single indictment. Trying those charges together may conserve judicial resources, but it can also expose a defendant to unfair prejudice. Federal Rules of Criminal Procedure 8 and 14 provide separate grounds for challenging the government’s decision to combine charges in one trial.

Rule 8 determines whether the charges were properly joined. Rule 14 permits the court to order separate trials when joinder would otherwise be proper but would unfairly prejudice the defendant. Call Federal Defense Attorney Michael J. Petro now to fight your federal case!

When May Federal Charges Be Joined Under Rule 8?

Rule 8(a) permits multiple offenses to be charged in the same indictment when the offenses:

• Are of the same or similar character

• Are based on the same act or transaction

• Are connected with, or constitute parts of, a common scheme or plan

The government does not need to satisfy all three grounds. Joinder may be permitted if any one of them applies.

When an indictment charges multiple defendants, Rule 8(b) generally controls. Defendants may be charged together if they allegedly participated in the same act, transaction, or series of acts or transactions constituting an offense. Not every defendant needs to be charged in every count.

A challenge under Rule 8 focuses primarily on the allegations appearing on the face of the indictment. The court asks whether the indictment describes a sufficient relationship among the charges or defendants. If the necessary connection is missing, the charges may have been misjoined.

Rule 14 Addresses Unfair Prejudice

Even when joinder is technically permitted under Rule 8, the court may order separate trials under Rule 14 if a combined trial creates a serious risk of prejudice.

A defendant seeking severance must identify specific harm that could prevent the jury from reaching a fair and reliable verdict. It is usually not enough to argue that the defendant might have a better chance of acquittal in separate trials.

Potential prejudice may arise when:

• Evidence supporting one count would not be admissible in a separate trial on another count

• A weak charge is joined with a much stronger charge

• Evidence concerning one offense may cause the jury to view the defendant as having a criminal character

• The jury may have difficulty separating the evidence applicable to each charge

• A felon-in-possession charge informs the jury that the defendant has a prior felony conviction

• Defendants present defenses that are genuinely irreconcilable

The government will often argue that limiting instructions can protect the defendant. Courts generally presume that jurors follow those instructions. A successful Rule 14 motion should therefore explain why an instruction cannot realistically eliminate the particular prejudice created by the combined trial.

Joinder of a Firearm Charge With Other Federal Offenses

Joinder can be especially significant when the indictment includes a charge under 18 U.S.C. § 922(g). To prove a felon-in-possession charge, the government must establish the defendant’s prohibited status. That information may influence the jury’s consideration of unrelated charges.

A defense attorney may seek severance so the jury deciding the other charges does not learn that the defendant has a prior felony conviction. The strength of that argument frequently depends on whether evidence of the firearm possession and the prior conviction would otherwise be admissible during a separate trial.

United States v. Carter

In United States v. Carter, 695 F.3d 690 (7th Cir. 2012), the defendants were charged with carjacking, using a firearm during the carjacking, and possessing a firearm as convicted felons. They argued that the felon-in-possession counts should have been tried separately.

The Seventh Circuit concluded that joinder was proper because the firearm counts involved the same Ruger pistol allegedly used during the carjacking, and possession occurred within approximately one day of that offense. The identity and possession of the firearm were central evidentiary issues for multiple counts.

The court also rejected the defendants’ Rule 14 argument. Although the jury learned that each defendant had a prior felony conviction, the defendants stipulated to their status, and the jury did not hear the nature or details of the prior offenses. The trial court also instructed the jury that the prior convictions could be considered only for the felon-in-possession charges.

Carter illustrates two important considerations. First, charges involving the same firearm and a close temporal connection are more likely to be joined. Second, severance becomes more difficult when evidence from one charge would also be admissible in a separate trial on the remaining charges.

The Difference Between Misjoinder and Severance

Rules 8 and 14 require different arguments.

A Rule 8 motion asserts that the charges or defendants should never have been joined under the governing legal standard. A Rule 14 motion accepts that joinder may be technically proper but argues that a combined trial would create an unacceptable risk of prejudice.

Defense counsel should ordinarily address both rules when the facts support both arguments. The motion should identify the evidence the jury would hear in a joint trial, explain whether that evidence would be admissible in separate trials, and describe why limiting instructions would not adequately protect the defendant.

Challenging Joinder in a Federal Criminal Case

Joinder can affect trial strategy, the evidence presented to the jury, and the defendant’s decision whether to testify. A motion to sever should be filed early and supported by a specific explanation of the prejudice created by a joint trial.
