Federal agents, working with a confidential informant, arranged a controlled narcotics transaction. In recorded telephone conversations, the informant spoke with an alleged co-conspirator who made statements indicating that a buyer—identified only as a "friend"—was prepared to purchase cocaine, would accompany him to the transaction, and had the necessary funds. The conversations detailed logistics about the time, place, and manner of the buy. At the appointed meeting, the petitioner, Bourjaily, arrived and acted consistently with the plan described on the recordings—meeting the co-conspirator, engaging in the transaction, and taking steps indicative of participation in the drug deal. The government sought to admit the co-conspirator's recorded statements against Bourjaily under Federal Rule of Evidence 801(d)(2)(E) (co-conspirator statements). Over defense objection, the district court admitted the statements after finding, based on a pretrial proffer and the combined force of the recordings and corroborating surveillance evidence, that a conspiracy existed, the declarant and Bourjaily were members, and the statements were made during and in furtherance of the conspiracy. A jury convicted Bourjaily. The court of appeals affirmed, and the Supreme Court granted certiorari.
In determining the admissibility of a co-conspirator's statement under Federal Rule of Evidence 801(d)(2)(E), may the trial court consider the hearsay statement itself, and what standard of proof governs the preliminary determination? Additionally, does admitting such statements violate the Confrontation Clause?
Under Federal Rule of Evidence 104(a), the trial judge decides preliminary questions of admissibility and is not bound by the rules of evidence (except those on privilege). For Rule 801(d)(2)(E), the government must prove by a preponderance of the evidence that: (1) a conspiracy existed; (2) both the declarant and the defendant were members; and (3) the statement was made during and in furtherance of the conspiracy. In making this determination, the court may consider the co-conspirator's statement itself. Admission of co-conspirator statements does not violate the Confrontation Clause where the statements fall within a firmly rooted hearsay exception. (Post-Bourjaily, Rule 801(d)(2) was amended to clarify that the contents of the statement are to be considered but do not, by themselves, establish the conspiracy or a party's participation.)
Yes. The court may consider the co-conspirator's statement itself in deciding admissibility under Rule 801(d)(2)(E), and the government must establish the foundational facts by a preponderance of the evidence under Rule 104(a). Admission of the statements did not violate the Confrontation Clause because the co-conspirator exception is a firmly rooted hearsay exception.
The Court began with Rule 104(a), which assigns preliminary evidentiary questions to the judge and frees the judge from most evidentiary constraints. The Court rejected a categorical prohibition on considering the hearsay statement itself ("no-bootstrapping" rule), noting that the Federal Rules contemplate a pragmatic approach: the judge may evaluate all available evidence—including the statement—when deciding whether the foundational conditions are met. The Court also selected the preponderance-of-the-evidence standard, reasoning that this is the default standard for preliminary evidentiary questions and strikes an appropriate balance between reliability and efficiency. The Court emphasized that the district court did not rely on the statement in isolation; there was independent corroboration (e.g., the defendant's arrival at the arranged time and place, conduct consistent with the plan, and surrounding circumstances). These facts, taken together with the statements, supported the conclusion that a conspiracy existed, that both the declarant and Bourjaily were members, and that the statements were made during and in furtherance of the conspiracy. On the Sixth Amendment issue, applying then-current Confrontation Clause doctrine (Ohio v. Roberts), the Court held that co-conspirator statements fall within a firmly rooted hearsay exception and thus carry sufficient indicia of reliability to satisfy the Constitution. The Court therefore rejected the argument that additional confrontation or reliability showings were required beyond satisfying Rule 801(d)(2)(E).
Bourjaily is the leading case on the evidentiary foundation for admitting co-conspirator statements. It establishes that judges decide admissibility under Rule 104(a) by a preponderance and may consider the statement itself—an approach that greatly influences how conspiracy cases are tried and how the government builds its foundation. Although the decision did not require independent evidence, a subsequent amendment to Rule 801(d)(2) clarified that a statement's contents must be considered but do not, by themselves, establish the conspiracy or a party's participation. For law students, Bourjaily concretely links Rules 104(a) and 801(d)(2)(E), illustrates the "during and in furtherance" requirement, and shows how constitutional and evidentiary analyses interact. Post-Crawford, co-conspirator statements are generally non-testimonial and thus typically admissible without confrontation, while Bourjaily continues to govern the evidentiary foundation under the Federal Rules.
Bourjaily v. United States supplies the doctrinal blueprint for admitting co-conspirator statements: judges decide admissibility, using a preponderance standard, and may consider the statements themselves along with other evidence. The decision harmonizes Rule 104(a) with Rule 801(d)(2)(E) and provides a functional approach that accommodates the realities of conspiracy prosecutions without sacrificing the safeguards of judicial gatekeeping.
