My client is charged with co-defendants. Do I try to get him his own trial, and how?

Step one: is the joinder even proper? (Fed. R. Crim. P. 8)

Before the prejudice analysis, the threshold question is whether the counts and the defendants belonged in the same indictment at all. Misjoinder is a distinct challenge from prejudice, and it is attacked on its own footing. The standard on each row is the rule’s own language; the note beside it is general method, not a claim about any case.

• Rule 8(a)

  Joinder of offenses

  The indictment or information may charge a defendant in separate counts with 2 or more offenses if the offenses charged, whether felonies or misdemeanors or both, are of the same or similar character, or are based on the same act or transaction, or are connected with or constitute parts of a common scheme or plan.

  The first question in any joint-defendant case is whether the counts and the defendants were properly joined in the first place, because misjoinder is a distinct challenge from prejudice: it asks whether the charges even belong in the same indictment, not whether a proper joinder should be undone for prejudice. Counsel reads each count against the same-or-similar-character, same-act-or-transaction, and common-scheme-or-plan standards and identifies any count that does not fit, because a misjoined count is attacked on its own footing before the Rule 14 prejudice analysis is reached.

• Rule 8(b)

  Joinder of defendants

  The indictment or information may charge 2 or more defendants if they are alleged to have participated in the same act or transaction, or in the same series of acts or transactions, constituting an offense or offenses. The defendants may be charged in one or more counts together or separately. All defendants need not be charged in each count.

  For co-defendants, the joinder question turns on whether they are alleged to have participated in the same act or transaction, or the same series of acts or transactions. Counsel tests the indictment against that standard: a defendant swept into a joint indictment on conduct that is not part of the alleged common series is a misjoinder candidate, and the point is preserved separately from the prejudice grounds. The rule expressly allows charging defendants together or separately and does not require every defendant to appear in every count, so the analysis is count-by-count and defendant-by-defendant.

The joinder standards are quoted from Fed. R. Crim. P. 8 (Cornell Legal Information Institute). The rule controls; confirm the current text and the controlling misjoinder authority in your circuit before relying on any of it.

Step two: the Fed. R. Crim. P. 14 prejudice grounds

Once joinder is proper, severance is sought under Fed. R. Crim. P. 14 to cure prejudice. Four grounds recur. Each is stated here as a general category, not as a holding: the controlling cases that state each ground, with their verbatim holdings and source URLs, live in the depth product and are pointed to below. The Bruton confrontation problem is the third ground and is the one most often decisive in a case with a co-defendant confession.

• Antagonistic defenses

  The first recurring ground is that the co-defendants' theories of the case are not merely different but irreconcilable, so that the jury cannot credit the moving defendant's defense without disbelieving the co-defendant's, or the reverse. The prejudice is that the jury is pushed to choose between defendants rather than to weigh each defendant's own case, and a co-defendant's counsel effectively becomes a second prosecutor against the moving defendant.

  Counsel shows the defenses are zero-sum on a contested element, not just inconsistent in tone, by laying the two theories side by side and identifying the fact on which crediting one necessarily convicts the other. The stronger the showing that the conflict is structural rather than rhetorical, the closer the ground sits to the Rule 14 prejudice standard.

• Evidentiary spillover

  The second recurring ground is that evidence admissible against a co-defendant, but not against the moving defendant, will be heard by the jury and cannot be reliably compartmentalized. A lower-culpability defendant's discrete conduct can be buried under voluminous, often more inflammatory, evidence of a co-conspirator's distinct conduct that would not come in at a separate trial. The prejudice is guilt by association and transferred inference.

  Counsel maps the evidentiary mismatch concretely: which exhibits, recordings, and counts feature the co-defendant and not the moving defendant, and what proportion of the trial the moving defendant is absent from. A structural evidentiary disparity, quantified, is what distinguishes real spillover prejudice from the ordinary friction every joint trial carries.

• The Bruton confrontation problem

  The third recurring ground is constitutional rather than evidentiary. When a non-testifying co-defendant's out-of-court statement is admitted at a joint trial and that statement implicates the moving defendant, the moving defendant cannot cross-examine the declarant, and the Confrontation Clause problem is direct. The general doctrine holds that a limiting instruction telling the jury to consider the statement only against the declaring co-defendant is an inadequate substitute for cross-examination when the statement is facially incriminating of the moving defendant, and that the government's ordinary cure, redaction, fails when the only redaction adequate to remove the implication would strip the statement of its value. This framework, and the cases that state it, is set out in full and cited to source in the depth product; it is summarized here as a general category, not reproduced with a holding.

  Counsel identifies whether the case carries a non-testifying co-defendant statement that points to the moving defendant by name, by description, or by obvious contextual reference, and whether any proposed redaction actually removes the implication or merely masks it. Because the injury is constitutional, the move is framed as the confrontation problem the joint trial creates, and the depth product's source-cited authorities are the drafting foundation.

• Disparity of evidence

  The fourth recurring ground is that the sheer imbalance between the evidence against the moving defendant and the evidence against the co-defendants, measured by what the jury will actually hear rather than by how the indictment reads, creates a serious risk that the jury cannot make a reliable, individualized judgment about the moving defendant. Disparity overlaps with spillover but is framed at the level of the whole evidentiary record, not a particular piece of evidence.

  Counsel quantifies the disparity across the record: hours of recordings featuring the moving defendant versus the co-defendants, counts naming the moving defendant versus the co-defendants, and the jury instructions that identify each defendant's specific role. A disparity that is structural, and shown to be structural, is what supports the argument that the joint trial threatens a reliable individualized judgment.

The severance grounds are worked under Fed. R. Crim. P. 14. How each ground is analyzed on your facts and in your circuit is a matter for your own research; confirm the controlling authority before relying on any of it.

The Bruton confrontation problem, as a general framework

The Bruton problem is worth setting out on its own because it is constitutional, not merely evidentiary. When a co-defendant who will not testify has given an out-of-court statement that implicates the moving defendant, admitting that statement at a joint trial gives the moving defendant no way to cross-examine the person who made it. The general doctrine holds that telling the jury to use the statement only against the co-defendant does not cure the problem when the statement is facially incriminating of the moving defendant, and that redaction fails when the only redaction adequate to remove the implication would strip the statement of its value. Stated at that level, the framework is a general category; the specific cases that state it, with their verbatim holdings and verified source URLs, are the drafting foundation carried in the depth product.

Step three: the relief the court can order (Fed. R. Crim. P. 14)

Fed. R. Crim. P. 14 fixes both the remedy menu and a tool the movant should invoke when the prejudice turns on the contents of a co-defendant statement. The standard on each row is the rule’s own language; the note is general method.

• Rule 14(a)

  The relief the court may order

  If the joinder of offenses or defendants in an indictment, an information, or a consolidation for trial appears to prejudice a defendant or the government, the court may order separate trials of counts, sever the defendants' trials, or provide any other relief that justice requires.

  The rule fixes the remedy menu: separate trials of counts, severance of the defendants' trials, or any other relief that justice requires. Counsel frames the motion to the specific relief the prejudice ground calls for, because a court will weigh a full severance differently from a narrower count-severance or a limiting measure, and the requested remedy should be the least drastic one that actually cures the identified prejudice.

• Rule 14(b)

  The in-camera inspection of a defendant's statement

  Before ruling on a defendant's motion to sever, the court may order an attorney for the government to deliver to the court for in camera inspection any defendant's statement that the government intends to use as evidence.

  The rule gives the court a tool the severance movant should invoke when the prejudice turns on the contents of a co-defendant statement: the court may order the government to hand over the statement for in-camera inspection before it rules. Counsel asks the court to use it, so the severance question is decided on the actual text of the statement and the actual proposed redaction rather than on the government's characterization of them.

The relief and the in-camera-inspection provisions are quoted from Fed. R. Crim. P. 14. The rule controls; confirm the current text before relying on any phrasing.

Step four: how and when to move

The mechanics of the motion sit alongside the doctrine. None of the steps below is a claim about any case: they are the general method the analysis assumes.

• Move before the government locks its trial posture

  A severance motion is timing-sensitive. The prejudice grounds are strongest, and the record for them is cleanest, before the government finalizes its trial-exhibit list and before the pretrial scheduling order treats a co-defendant statement as admissible. Counsel files on the schedule the local rules and the court's scheduling order set, and treats a Bruton-class statement as a reason to move early rather than to wait, because a mid-trial severance is a remedy of last resort with mistrial and double-jeopardy costs that a pretrial ruling avoids.

• Separate the misjoinder challenge from the prejudice challenge

  Misjoinder under Rule 8 and prejudicial joinder under Rule 14 are distinct arguments with distinct standards, and counsel keeps them separate in the motion. The Rule 8 argument attacks whether the counts or defendants belonged together at all; the Rule 14 argument accepts proper joinder and asks for severance to cure prejudice. Pleading both, in the right order, preserves each point and keeps the court from collapsing a misjoinder question into a discretionary prejudice balance.

• Show the prejudice with specifics, not labels

  Whichever Rule 14 ground the motion invokes, the showing is specific and particular, not a recitation of the category. Antagonistic-defense motions identify the contested element on which the defenses are zero-sum; spillover and disparity motions quantify the evidentiary mismatch; a Bruton motion identifies the statement, the implication, and why the proposed redaction fails. The specificity is what separates a grantable motion from a generic one, and it is drawn from the case record, not from the doctrine in the abstract.

The timing and mechanics are general drafting method. How a severance motion is filed and preserved in your district, and the controlling standard on review, are matters for your own research; the two rules are cited to Fed. R. Crim. P. 8 and Fed. R. Crim. P. 14.

Turn the analysis into the filed motion

The analysis runs in order: first, is the joinder even proper under Rule 8, because a misjoined count or defendant is attacked on its own footing before prejudice is reached; second, which Rule 14 prejudice ground the case presents, whether antagonistic defenses, evidentiary spillover, the Bruton confrontation problem, or disparity of evidence, and how each is shown with specifics from the record; third, what Rule 14 relief fits the prejudice, from a full severance down to a narrower count-severance or a limiting measure, and whether to ask the court to inspect a co-defendant statement in camera before it rules; and fourth, when to move, which is before the government locks its trial posture. The goal is a motion the court can grant on a clean pretrial record rather than a mid-trial severance forced by a problem that should have been raised earlier.

This framework is the shape of the analysis. The Severance & Joinder Motion Pack is the source-cited depth product built to ground it: two pre-drafted motion templates, the Bruton redaction-failure severance for the non-testifying co-defendant statement, and the Zafiro spillover-prejudice severance for antagonistic defenses and disparity, each with the lead authority’s verbatim holding, the attaching precedent, editable motion language, and a reply-brief framework. The cousin shares the case: the free cross-examine-a-cooperating-witness framework is what you reach for when the co-defendant testifies instead of staying silent.
