Federal Grand Jury Subpoenas and Target Letters in Minnesota

What a Grand Jury Subpoena Is

A federal grand jury is a group of citizens, drawn from across the District of Minnesota, that investigates possible federal crimes and decides whether to indict. To gather evidence, the grand jury — acting at the prosecutor's request — can issue subpoenas. There are two main types: a subpoena to produce documents or records (subpoena duces tecum), and a subpoena to appear and testify (subpoena ad testificandum). A subpoena is a court command; ignoring it can lead to contempt. But how to respond — what's actually required, what privileges apply, what to produce and what to withhold — is a legal question best answered with counsel before the deadline.

Target, Subject, or Witness

Federal prosecutors generally think of people in an investigation in three categories:

• Target — someone the prosecutor believes committed a crime and is likely to charge. A "target letter" formally conveys this status.
• Subject — someone whose conduct is within the scope of the investigation, where the evidence isn't yet there to charge. A subject sits between target and witness.
• Witness — someone with relevant information but low criminal exposure.

These labels are not permanent. A witness can become a subject, and a subject can become a target — sometimes based on what the person says. That fluidity is exactly why people who think they're "just a witness" still need advice before talking.

What a Target Letter Means

A target letter typically informs you that you are a target of a grand jury investigation, identifies the general area of conduct, and may invite you to testify or to have your lawyer contact the prosecutor. Receiving one is serious — but it is also an opportunity. The pre-indictment period is sometimes the best chance to present your side, correct the government's understanding, negotiate, or persuade prosecutors not to charge. That work has to happen before the grand jury votes.

Your Rights

• The Fifth Amendment. You generally cannot be forced to give self-incriminating testimony. A witness can assert the privilege rather than answer.
• Counsel. You have the right to a lawyer — but a witness's lawyer is not allowed inside the grand jury room during testimony. In practice, the witness may step out to consult counsel.
• Immunity. The government can compel testimony by granting immunity, which changes the calculus significantly and should never be navigated without counsel.
• Privileges. Attorney-client and other privileges can shield certain communications and documents from a subpoena.

Grand Jury Secrecy

Federal grand jury proceedings are secret by law. Prosecutors and grand jurors must keep the proceedings — even the existence of an investigation — confidential, generally until an indictment is returned. That secrecy is one reason it can be hard to know exactly where you stand, and why a lawyer's communication with the prosecutor is often the practical way to learn more.

What Not to Do

Two mistakes are especially costly: talking to agents or the grand jury without preparation, and doing anything that looks like destroying or altering documents after learning of an investigation — which can itself become an obstruction charge far more serious than the original inquiry. The safe move on receiving a subpoena or target letter is to preserve everything and call a lawyer.
