The Grand Jury: Subpoenas, Witness Status, and What Secrecy Actually Covers
A grand jury subpoena is the first visible step in an investigation that has usually been running for months. This brief explains what it compels, what it does not, and the sequence that follows.
- Federal Rule of Criminal Procedure 6 governs the grand jury, and its secrecy obligation binds prosecutors, jurors, and court staff — not witnesses.
- Recipients should establish immediately whether they are a witness, a subject, or a target, because the three call for different responses.
- A company has no privilege against self-incrimination, and its records custodian generally cannot refuse to produce on personal Fifth Amendment grounds.
