Definition
A joint indictment is a single indictment charging two or more defendants together for offenses arising out of the same criminal act or transaction. Rather than pursuing separate indictments against each accused, the grand jury returns one instrument that names multiple defendants and sets out the charges against them collectively.
The joint indictment may encompass defendants who played different roles in the same offense — principals in the first degree (those who directly committed the act), principals in the second degree (those present and aiding), and accessories before or after the fact — all joined within a single charging document. It may also charge co-defendants who jointly participated in an ongoing criminal enterprise, such as the joint operation of an illegal gaming establishment, where the offense itself is inherently shared rather than personal to any one defendant.

Common Confusion
JOINT INDICTMENT vs. JOINDER OF OFFENSES: A joint indictment joins multiple defendants in one charging document. Joinder of offenses, by contrast, joins multiple charges against a single defendant in one indictment. The two concepts operate on different axes — defendants versus charges — and conflating them leads to errors when researching severance motions, prejudice arguments, and procedural remedies, which differ substantially depending on which type of joinder is at issue.
JOINT INDICTMENT vs. CONSOLIDATION: A joint indictment is issued by the grand jury at the charging stage. Consolidation is a later judicial act that combines separately issued indictments for trial purposes. Historical sources sometimes use the terms loosely; researchers should confirm which procedural stage an authority is discussing.

Why It Matters in Research
The joint indictment sits at the intersection of grand jury procedure, joinder doctrine, and defendants' constitutional rights — three areas that evolved substantially across the nineteenth and twentieth centuries, and where historical sources require careful handling.
GRAND JURY CONTEXT: The Fifth Amendment Grand Jury Clause constrains federal practice but was not incorporated against the states. Researchers working with state-court materials from any era must check the applicable state constitutional provision and statutory joinder rules, which vary widely. A source written about English common law practice or early federal practice may not translate directly to a given state's regime.
SEVERANCE AS THE PRACTICAL COUNTERPART: Any research into joint indictments should immediately extend to severance doctrine. A joint indictment creates the procedural posture that severance motions are designed to address. Prejudice arguments — including spillover evidence, antagonistic defenses, and Bruton problems (where a non-testifying co-defendant's confession implicates the other defendant) — arise specifically because defendants were joined. Historical sources predate Bruton v. United States (1968) and the modern constitutional framework surrounding co-defendant confessions; entries from Bouvier and Burrill are silent on these concerns entirely.
ACCESSORIES AND THE HISTORICAL CONTEXT: The early authorities, including Hale's Pleas of the Crown cited in Black's and Burrill's, reflect a common law system that formally distinguished principals in the first and second degree and accessories before and after the fact as separate legal categories with separate charging implications. Many American jurisdictions later abolished or collapsed these distinctions by statute. Researchers using historical indictment forms or early treatises should verify whether the jurisdictional distinction between principal and accessory still carried legal significance at the time of the source.
GAMING HOUSE ILLUSTRATION: Bouvier's use of a joint gaming house indictment as an illustrative example reflects a category of offense — joint maintenance of a nuisance or illegal establishment — where criminal liability was understood as inherently shared. This connects joint indictment doctrine to the broader body of joint criminal liability and conspiracy law. Researchers should be alert to the fact that what earlier authorities treated as a joint indictment problem is often reframed in modern practice as a conspiracy charge, which carries its own distinct procedural and evidentiary rules.
CORPUS TRAPS: The term appears in older procedural treatises primarily as a description of grand jury practice rather than as a doctrinal category with its own body of case law. Searches on the term alone may underreturn relevant material; effective research requires parallel searching under joinder, severance, co-defendants, and conspiracy.

Historical Dictionary Support
The four source dictionaries are consistent in their core definition: a joint indictment is one that names and charges multiple defendants in a single instrument. Burrill offers the most economical statement. Black's and Rapalje & Lawrence expand slightly to enumerate the range of parties who might be joined — principals and accessories — tracing to Hale's Pleas of the Crown. Bouvier adds the most doctrinal texture, noting that the joint indictment is appropriate "where there is a joint criminal act, without any regard to any particular personal default or defect of either of the defendants," and illustrating with the gaming house example drawn from Ventris and Hawkins.
None of the historical sources address the constitutional dimensions that modern practice requires — the Sixth Amendment right to confrontation, severance standards, or the prejudice analysis now central to joinder litigation. This is expected given their period, but it is the most significant gap for a researcher using these sources to understand contemporary doctrine. The historical entries are useful for understanding the common law conceptual baseline; they are insufficient as a guide to modern federal or state joinder rules.

Jurisdictional Note
Federal practice is governed by Federal Rule of Criminal Procedure 8(b), which permits joinder of defendants alleged to have participated in the same act or transaction or series of acts or transactions constituting an offense. State rules vary; some track the federal model closely while others impose more or less permissive joinder standards. The constitutional floor — particularly Fifth Amendment grand jury requirements — applies only in federal court.
