3.4 Grand Jury Indictment, Information & Arraignment (Rules 6, 7 & 10)

Key Takeaways

  • The Fifth Amendment mandates that federal felony prosecutions proceed by Grand Jury Indictment, unless waived under Rule 7(b); Rule 6 requires 16–23 grand jurors, a 16-juror quorum, and 12 concurring votes for a True Bill.
  • Grand jury secrecy under Fed. R. Crim. P. 6(e) strictly binds court interpreters, prosecutors, and grand jurors under penalty of criminal contempt, whereas witnesses are exempt.
  • An Indictment emanates from a citizen grand jury, whereas an Information is filed directly by the United States Attorney, permissible in felony cases only upon explicit written waiver in open court.
  • Arraignment under Fed. R. Crim. P. 10 requires formal identification, presentation of charges, and entry of a plea: Not Guilty, Guilty, or Nolo Contendere (with court leave).
  • The Speedy Trial Act of 1974 (18 U.S.C. § 3161) mandates filing an indictment within 30 days of arrest and commencing trial within 70 days, subject to statutory excludable delay.

3.4 Grand Jury Indictment, Information & Arraignment (Rules 6, 7 & 10)

The progression of a federal criminal case from initial complaint to formal trial is anchored in the Fifth Amendment's Grand Jury Clause and the Federal Rules of Criminal Procedure. Once the initial appearance and detention hearings conclude, the prosecution must obtain a formal charging instrument—either an Indictment returned by a Grand Jury or an Information filed by the United States Attorney—culminating in the defendant's formal Arraignment in Open Court under Rule 10. For federal court interpreters, this phase tests command of grand jury secrecy rules, charging instruments, complex conspiracy allegations, and the rigorous statutory timetable of the Speedy Trial Act of 1974.


1. Constitutional Grand Jury Mandate & Composition (Fed. R. Crim. P. 6)

The Fifth Amendment to the United States Constitution commands:

"No person shall be held to answer for a capital, or otherwise infamous crime, unless on a presentment or indictment of a Grand Jury..."

In federal jurisprudence, an "infamous crime" (delito grave / delito infamante) is defined as any felony punishable by death or by imprisonment for a term exceeding one year. The Grand Jury operates as an independent constitutional body serving a dual historical function: a sword empowering the government to investigate suspected crimes through subpoena powers, and a shield protecting citizens against unfounded, malicious, or arbitrary prosecutions.

Federal Rule of Criminal Procedure 6 Requirements:

  • Composition (Composición del gran jurado): A federal grand jury consists of 16 to 23 citizens impaneled from the district's voter registration or actual voter lists.
  • Quorum (Quórum legal): At least 16 grand jurors must be present to hear testimony, examine evidence, and deliberate.
  • Concurrence for a True Bill (Concurrencia para una acusación aprobada): An indictment may be found only upon the concurrence of at least 12 grand jurors (Rule 6(f)).
  • True Bill vs. No Bill:
    • True Bill (Acusación formal aprobada / causa fundada): Endorsed by the Foreperson (presidente del gran jurado), certifying that at least 12 grand jurors found probable cause.
    • No Bill (Falta de mérito / acusación desestimada): Indicates the grand jury rejected the proposed indictment for lack of probable cause.

2. Grand Jury Secrecy under Rule 6(e) & The Court Interpreter's Oath

Grand jury proceedings are conducted in absolute secrecy. Unlike trial juries, there is no judge presiding in the room, no defense counsel present, and the public and press are strictly excluded. The only persons permitted inside the grand jury room during testimony under Rule 6(d) are the attorneys for the government, the witness under examination, court reporters, recording operators, and interpreters.

The Strict Scope of Rule 6(e) Secrecy

Under Federal Rule of Criminal Procedure 6(e)(2)(B), the obligation of secrecy binds:

  1. Grand jurors;
  2. Interpreters (Fed. R. Crim. P. 6(e)(2)(B)(vii));
  3. Court reporters and recording device operators;
  4. Attorneys for the government and their authorized support personnel.

CRITICAL FCICE ETHICAL & LEGAL POINT: Under Rule 6(e)(2)(B)(vii), court interpreters are explicitly bound to grand jury secrecy. An interpreter who discloses any witness testimony, document, target name, or grand jury deliberation is subject to criminal prosecution for criminal contempt of court (desacato penal al tribunal) under 18 U.S.C. § 401.

The Witness Exemption (Rule 6(e)(2)(A)): "No obligation of secrecy may be imposed on any person except in accordance with Rule 6(e)(2)(B)." In federal practice, witnesses who testify before a grand jury are NOT bound by secrecy. A witness is legally free to walk out of the grand jury room and discuss their testimony with the media, target individuals, or defense counsel, unless a specific judicial protective order applies.


3. Indictment vs. Information & Waiver of Indictment (Fed. R. Crim. P. 7)

Federal criminal practice utilizes two primary charging instruments, each possessing distinct constitutional attributes:

+-----------------------------------------------------------------------------+
|                   INDICTMENT VS. INFORMATION COMPARISON                     |
+-----------------------------------------------------------------------------+
| INDICTMENT (*Acusación formal del gran jurado / auto acusatorio*)           |
| - Returned exclusively by a Grand Jury (minimum 12 concurring votes).       |
| - Constitutionally mandatory for all federal felonies (5th Amendment).     |
| - Does not require defendant's consent to be filed.                         |
+-----------------------------------------------------------------------------+
| INFORMATION (*Acusación fiscal / pliego acusatorio directo*)                |
| - Filed directly by the United States Attorney without a grand jury.        |
| - Permissible for Class A, B, and C misdemeanors and petty offenses.        |
| - In FELONY prosecutions, permissible ONLY IF the defendant executes a      |
|   formal WAIVER OF INDICTMENT in open court under Rule 7(b).                |
+-----------------------------------------------------------------------------+

The Rule 7(b) Waiver of Indictment Colloquy

Under Federal Rule of Criminal Procedure 7(b), an offense punishable by imprisonment for more than one year may be prosecuted by Information if the defendant—in open court and after being advised of the nature of the charge and of the defendant's rights—waives prosecution by indictment in writing.

Waivers of indictment are standard in negotiated plea dispositions (acuerdos de culpabilidad negociados). When a cooperating defendant agrees to plead guilty prior to grand jury indictment, the parties file an Information charging the agreed-upon count, accompanied by a written Rule 7(b) waiver executed before the district judge.


4. Superseding Indictments, Joinder & Co-Conspirators

As federal investigations mature, the initial charging instrument is frequently amended or expanded:

  • Superseding Indictment (Acusación formal sustitutiva / pliego acusatorio modificatorio): A subsequent indictment returned by the grand jury that completely replaces and supersedes the prior indictment. It is commonly used to add new substantive criminal counts, incorporate forfeiture allegations (pretensiones de decomiso de bienes), correct statutory technicalities, or join additional co-defendants.
  • Joinder of Offenses & Defendants (Rule 8):
    • Joinder of Offenses (Rule 8(a)): Charging multiple offenses against a single defendant if the crimes are of the same or similar character, or are based on the same act or transaction.
    • Joinder of Defendants (Rule 8(b)): Indicting multiple co-defendants (coacusados) in a single charging instrument if they are alleged to have participated in the same series of acts or transactions constituting an offense (e.g., narcotics or RICO conspiracies).
  • Unindicted Co-Conspirators (Coconspiradores no procesados / no acusados): Individuals named or referenced in the narrative paragraphs of an indictment as participants in an unlawful conspiracy, but who are not formally named as defendants in the charging caption (frequently because they are cooperating witnesses, deceased, or indicted in another jurisdiction).

5. Arraignment in Open Court (Fed. R. Crim. P. 10) & The Three Pleas

Once an indictment or information is filed, the defendant is summoned for Arraignment in Open Court (instrucción formal de cargos / lectura de cargos) under Federal Rule of Criminal Procedure 10.

The Four Requisites of Rule 10:

  1. Open Court Proceeding: The arraignment must be conducted in open court (or by video teleconference under Rule 10(c) with defendant consent).
  2. Delivery of Charging Instrument: A physical copy of the indictment or information must be delivered to the defendant.
  3. Reading or Stating Substance of Charge: The court reads the indictment or states the substance of the charge on the record (defense counsel routinely "waives the formal reading of the indictment" / renuncia a la lectura formal del auto acusatorio).
  4. Calling Upon the Defendant to Plead: The court formally asks the defendant how they plead to each count.

The Three Recognized Pleas (Fed. R. Crim. P. 11(a)(1)):

  1. Not Guilty (No culpable): The standard initial plea entered at arraignment. Preserves all constitutional trial rights, discovery motions, and procedural defenses.
  2. Guilty (Culpable): Formal admission of factual guilt, relinquishing the right to trial, confrontation of witnesses, and privilege against self-incrimination.
  3. Nolo Contendere (No me opongo / no disputo los cargos / nolo contendere): A plea whereby the defendant accepts criminal conviction without admitting civil liability. Under Rule 11(a)(3), a plea of nolo contendere requires the consent of the court, which is granted only after considering the views of the parties and the public interest in the effective administration of justice.

Standing Mute (Guardar silencio procesal): Under Fed. R. Crim. P. 11(a)(4), if a defendant refuses to enter a plea or stands mute, the court must enter a plea of not guilty on the defendant's behalf.


6. The Speedy Trial Act of 1974 (18 U.S.C. § 3161)

The Sixth Amendment guarantees the right to a speedy trial. In federal courts, this constitutional right is strictly quantified and enforced by the Speedy Trial Act of 1974 (18 U.S.C. §§ 3161–3174).

The Dual Statutory Timelines:

  1. The 30-Day Indictment Clock (18 U.S.C. § 3161(b)): Any information or indictment charging an individual with an offense must be filed within 30 calendar days from the date on which the individual was arrested or served with a summons.
  2. The 70-Day Trial Clock (18 U.S.C. § 3161(c)(1)): The trial of a defendant charged in an information or indictment must commence within 70 calendar days from:
    • The filing date of the information or indictment; OR
    • The date the defendant appeared before a judicial officer of the court in which the charge is pending, whichever date occurs later.

Excludable Delay & Tolling (§ 3161(h))

Crucially, the 70-day clock does not run continuously. Under 18 U.S.C. § 3161(h), specific periods of delay are excluded from the computation (tolled / plazos excluidos o suspendidos):

  • Delay resulting from competency examinations or interlocutory appeals (§ 3161(h)(1)(A), (C)).
  • Delay resulting from any pretrial motion, from the date filed through the date disposed of (§ 3161(h)(1)(D)).
  • Delay attributable to plea negotiations and agreements (§ 3161(h)(1)(G)).
  • Ends-of-Justice Continuances (§ 3161(h)(7)(A)): The court may grant a continuance tolling the clock if the judge makes specific oral or written findings on the record that "the ends of justice served by taking such action outweigh the best interest of the public and the defendant in a speedy trial." Common grounds include complex multi-defendant conspiracies, voluminous wiretap discovery, or novel questions of law.

Sanctions for Violation (§ 3162)

If the 70-day clock expires without commencement of trial and without lawful excludable time, the court must dismiss the indictment on motion of the defendant (18 U.S.C. § 3162(a)(2)). The court has discretion to dismiss with prejudice (con sobreseimiento definitivo / sin derecho a nuevo juicio) or without prejudice (sin sobreseimiento definitivo / con derecho a reiniciar la acción penal), balancing factors such as crime seriousness, delay culpability, and impact on the administration of justice.

THE DEFENDANT / EL ACUSADO (through Interpreter): "Yes, Your Honor."

"Sí, Su Señoría."

THE COURT / EL JUEZ: "Counsel, do you wish to have the indictment read in open court, or do you waive the formal reading?"

"Licenciado, ¿desea que se dé lectura al pliego acusatorio en audiencia pública, o renuncia a la lectura formal?"

DEFENSE COUNSEL / EL ABOGADO DEFENSOR: "Your Honor, we waive the formal reading of the indictment. We enter a plea of not guilty to all counts, and we request the standard 30-day pretrial motion schedule. We also note for the record that we do not waive our rights under the Speedy Trial Act."

"Su Señoría, renunciamos a la lectura formal del auto acusatorio. Interponemos una declaración de no culpable para todos los cargos y solicitamos el plazo ordinario de 30 días para la interposición de pedimentos previos al juicio. Asimismo, hacemos constar en actas que no renunciamos a nuestros derechos al amparo de la Ley de Juicio Rápido."

THE COURT / EL JUEZ: "The record shall reflect that the defendant waives reading of the Indictment and enters a plea of Not Guilty as to Counts One, Two, and Three. Pretrial motions shall be filed within 30 days. The court sets a jury trial date for November 12, 2026. The time between today and the motion filing deadline is excluded under the Speedy Trial Act pursuant to 18 U.S.C. § 3161(h)(1)(D). Remand to custody. We are adjourned."

"Conste en actas que el acusado renuncia a la lectura del Auto Acusatorio e interpone una declaración de No Culpable en cuanto a los Cargos Uno, Dos y Tres. Los pedimentos previos al juicio deberán presentarse en un plazo de 30 días. El tribunal fija la fecha de inicio del juicio por jurado para el 12 de noviembre de 2026. El lapso comprendido entre el día de hoy y la fecha límite para la radicación de pedimentos queda excluido del cómputo de la Ley de Juicio Rápido al amparo del artículo 3161(h)(1)(D) del Título 18 del Código de los Estados Unidos. Se ordena su reclusión preventiva. Se levanta la sesión."
