Recorded Conversation Between Indicted Parties
Jeanette Jensen and Jessica Jacobs were indicted together on fraud charges. Police arranged for an informant to record their jailhouse discussion about the scheme. The recording captured incriminating statements from both. The court suppressed the statements obtained from the joint defendant because the deliberate elicitation violated the Sixth Amendment right to counsel.
Diversity Action Against Multiple Parties
Jada Jones sued Jones Petroleum and Jarvis Aviation in state court for breach of contract. Jones Petroleum removed the case to federal court on diversity grounds. Jarvis Aviation never consented to removal. The court remanded because all properly joined and served joint defendants must join or consent to removal.

Dictionaries
Judy Jacobs and Jeffrey Jha were tried jointly for robbery. The prosecution introduced a confession by Jha that named Jacobs as the getaway driver. Jha did not testify. The court held the admission violated Jacobs's confrontation rights even with a limiting instruction because the joint defendant had no opportunity for cross-examination.
Bruton v. United States391 U.S. 123 (1968)
Search of Shared Vehicle
Jacob Jennings and Jeanette Jensen were stopped in a borrowed car. Officers found contraband during a search. Jennings moved to suppress the evidence. The court denied the motion because a joint defendant who was merely a passenger lacked a legitimate expectation of privacy in the vehicle.
Rakas v. Illinois439 U.S. 128 (1978)
Plea Agreement in Multi-Party Case
Jessica Jacobs and Jada Jones faced bank robbery charges. Jacobs accepted a plea deal that required her to testify against Jones. The court accepted the plea after confirming it was voluntary. The joint defendant's agreement did not automatically bind Jones or require her consent.
Brady v. United States397 U.S. 742 (1970)
Harmless Error Review in Joint Trial
Judy Jacobs and Jeffrey Jha were convicted after a joint trial that included an improper comment on Jacobs's silence. The appellate court applied harmless-error analysis to the constitutional violation. It concluded the error did not affect the verdict against the joint defendant because overwhelming independent evidence supported the conviction.

Common questions
Frequently Asked
3
Does a joint defendant have independent rights to counsel during police questioning?+
Yes. Each joint defendant retains a separate Sixth Amendment right to counsel once indicted. Police may not deliberately elicit incriminating statements from one through the other without counsel present.
Supporting sources
When does admission of one joint defendant's confession violate the other's confrontation rights?+
Admission violates the Confrontation Clause in a joint trial if the non-testifying co-defendant's confession directly implicates the defendant, even with a limiting instruction. Redactions that obviously point to the defendant are also insufficient.
Supporting sources
Must all joint defendants consent to removal in a diversity case?+
Yes. The rule of unanimity requires every properly joined and served defendant to join in or consent to removal. Failure by any joint defendant renders the removal procedurally defective and subject to remand.
