A federal grand jury consists of 16-23 citizens who sit secretly to hear evidence and decide whether probable cause exists to indict a defendant. The Fifth Amendment requires grand jury indictment for federal felonies. The grand jury is the prosecutor's investigative tool — defendants and defense counsel do not appear, and the jury sees only the government's evidence.
Composition and term
Federal grand juries consist of 16 to 23 citizens drawn from the district's jury pool. They sit for a term of approximately 18 months (extendable in complex investigations), meeting one or more days per week to hear matters presented by the U.S. Attorney's Office.
Federal grand juries are constituted under 18 U.S.C. §§ 3321-3334 and Federal Rule of Criminal Procedure 6. The court summons grand jurors from the district's jury wheel under the Jury Selection and Service Act, 28 U.S.C. § 1861. Each grand jury sits for an initial 18-month term, extendable by court order up to 24 months total (or longer for special grand juries investigating organized crime or other specified matters).
Grand juries meet on a regular schedule — typically one or two days per week in busier districts. The U.S. Attorney's Office schedules witnesses, presents evidence, and answers grand-jury questions through Assistant U.S. Attorneys. A foreperson and deputy foreperson are designated to administer oaths and authenticate documents on behalf of the panel.
To indict a defendant, twelve grand jurors must concur on each count of the indictment under Federal Rule of Criminal Procedure 6(f). Fewer than twelve is "no true bill" and the charge is not returned (though it can be presented again, sometimes to a different grand jury). The grand jurors themselves do not write the indictment — it is drafted by the prosecutor and presented for vote.
Secrecy and disclosure
Grand jury proceedings are governed by strict secrecy rules under Federal Rule of Criminal Procedure 6(e). Disclosure is limited to a defined list of officials and circumstances. Defense counsel typically has no access to grand jury transcripts pre-indictment.
Rule 6(e) imposes secrecy obligations on grand jurors, court reporters, U.S. Attorney's Office personnel, and any persons providing services to the grand jury. Disclosure outside specifically permitted categories is itself contempt of court. The witness who appears before the grand jury is not subject to the secrecy obligation — the witness may discuss their own testimony with counsel, family, or anyone else.
Permitted disclosures under Rule 6(e)(3): to attorneys for the government in connection with their duties; to other federal personnel who need the information for investigative or prosecutive purposes; to a foreign government in specified investigations; to state or local officials in narrow circumstances; and to the defendant after indictment, with limited subject-matter restrictions.
Defense counsel typically does not access grand jury transcripts until after indictment, and even then disclosure is limited to the defendant's own statements and (under Brady/Giglio) to materially exculpatory or impeaching grand-jury testimony. Some prosecutors voluntarily provide broader grand-jury transcript disclosure; others adhere strictly to minimum requirements.
Target, subject, and witness status
The Department of Justice Manual recognizes three statuses for persons in a grand jury investigation: target, subject, and witness. Each carries different rights and strategic implications.
The DOJ Manual § 9-11.151 defines a target as "a person as to whom the prosecutor or the grand jury has substantial evidence linking him or her to the commission of a crime and who, in the judgment of the prosecutor, is a putative defendant." Targets are typically advised of their status by target letter or in counsel-to-counsel communication.
A subject is a person whose conduct is within the scope of the grand jury investigation but whose status has not yet ripened into target. Subjects are not usually advised in writing; the status is conveyed informally to counsel.
A witness is a person who has information relevant to the investigation but is not implicated as a perpetrator. Witnesses are typically called by subpoena to provide testimony or documents. Witness status can shift to subject or target status as the investigation develops, particularly if the witness's own statements implicate them or if previously unknown conduct comes to light.
Defense strategy varies by status. Witnesses cooperate if cooperation is in their interest; targets typically should not testify at all (Fifth Amendment); subjects need a careful evaluation, often through proffer dialogue with the prosecutor.
Witness appearance before the grand jury
Witnesses summoned to testify appear personally before the grand jury. The witness has the right to consult counsel outside the grand jury room, to invoke the Fifth Amendment, and to seek immunity in some circumstances. Counsel does not appear inside the grand jury room.
A witness who receives a grand jury subpoena consults counsel about the appearance. Counsel cannot enter the grand jury room — Federal Rule of Criminal Procedure 6(d) limits attendance to grand jurors, the prosecutor, the court reporter, the witness, and interpreters. However, the witness may leave the room at any time to consult with counsel about a specific question, then return to answer.
The witness is sworn and asked questions by the prosecutor. Grand jurors may also ask questions through the prosecutor or directly. Common Fifth Amendment invocations: any question that could provide a "link in the chain" of incriminating evidence against the witness. Immunity orders under 18 U.S.C. §§ 6002-6003 can compel testimony notwithstanding the Fifth Amendment privilege; the immunity is "use" immunity (the testimony cannot be used directly or derivatively against the witness in a criminal prosecution).
Tactical decisions before the grand jury include: when to invoke the Fifth Amendment on each question vs. en bloc; whether to assert other privileges (attorney-client, work product); how to handle leading questions or compound questions; whether to request a recess to consult counsel. Each decision is fact-specific. The transcript is recorded and becomes the witness's permanent statement under oath.

FAQ
What is the practical importance of this topic in a federal case?
Federal criminal practice is governed by precise procedural rules, and the topic of grand jury is a recurring high-stakes decision point. Failure to handle the procedural step correctly can result in waiver of significant rights or loss of strategic position. Defense counsel familiar with federal practice navigates these decisions routinely; defendants without counsel routinely make procedural missteps that affect the case outcome.
Does this topic apply in both the Northern and Eastern Districts of Texas?
Yes. The Federal Rules of Criminal Procedure and the U.S. Code apply uniformly across federal districts, including the U.S. District Court for the Northern District of Texas (TXND, headquartered in Dallas and Fort Worth) and the U.S. District Court for the Eastern District of Texas (TXED, with the Sherman division covering Collin, Denton, and Grayson counties). Local rules and individual judge practices vary, but the substantive framework is the same.
Should I retain counsel specifically for this phase?
Yes, in almost all cases. Federal criminal practice is a specialized field — substantively distinct from state practice, with different rules, deadlines, and strategic considerations. Counsel admitted to practice in TXND, TXED, and the Fifth Circuit (and ideally with experience in the type of offense charged) is the appropriate choice. Local state-court practitioners without federal-court admission cannot appear in federal cases.
