What To Expect If You Receive A Federal Grand Jury Subpoena
Receiving a federal grand jury subpoena can feel overwhelming, even if you think you have done nothing wrong. The subpoena might ask you to appear before a grand jury, hand over business records, provide electronic communications, or share financial information. Often, it gives little detail about the investigation, who is involved, or why the evidence is needed. Receiving a subpoena does not automatically mean you will be charged with a crime, but you should not treat it as a simple request. Anything you say, provide, keep, delete, or leave out could influence the investigation and could put you at risk.
Federal grand jury proceedings are governed primarily by federal law rather than Texas criminal procedure. This distinction is important for anyone serving in Galveston or the Houston area. A federal grand jury subpoena may arise from an investigation conducted by the Federal Bureau of Investigation, the Drug Enforcement Administration, the Internal Revenue Service Criminal Investigation, the Department of Homeland Security, the Bureau of Alcohol, Tobacco, Firearms and Explosives, or another federal agency. We advise people to obtain legal counsel promptly so that their rights, obligations, and possible status in the investigation can be assessed before they respond.
Understanding The Purpose Of A Federal Grand Jury
A federal grand jury is an investigative body that determines whether probable cause exists to believe that a federal crime was committed. Unlike a trial jury, a grand jury does not decide guilt or innocence. Its function is to hear evidence presented by federal prosecutors and decide whether criminal charges should be filed through an indictment.
Rule 6 of the Federal Rules of Criminal Procedure governs federal grand jury proceedings. The rule generally requires prosecutors, grand jurors, court reporters, interpreters, and certain other participants to protect the secrecy of matters occurring before the grand jury. The witness, however, is not automatically subject to the same general secrecy obligation merely because the witness testifies, although a court order or another legal restriction may affect what can be disclosed.
Grand juries have broad investigative authority. Federal prosecutors may use subpoenas to obtain testimony, documents, recordings, electronic data, financial files, photographs, business records, and other evidence that may be relevant to a federal investigation. This authority is broad, but it is not unlimited. A subpoena may sometimes be challenged when it is unreasonably burdensome, seeks privileged information, lacks sufficient relevance, or is otherwise legally defective.
A Subpoena May Demand Testimony Or Documents
Federal Rule of Criminal Procedure 17 governs subpoenas in federal criminal proceedings. A subpoena may command a person to appear at a specified location and provide testimony. It may also require the recipient to produce books, papers, electronically stored information, recordings, physical objects, or other designated materials.
Some subpoenas require both testimony and document production. Others are directed to a business and request records held by the company. The scope may be narrow, such as communications with one person during a limited period, or it may cover years of banking, accounting, payroll, telephone, email, or customer records.
Before producing anything, we examine each demand carefully. Terms used in the subpoena may be vague or much broader than they initially appear. For example, a request for “communications” may include emails, text messages, messaging applications, attachments, photographs, drafts, cloud files, and metadata. A recipient who produces records without understanding the language may inadvertently provide privileged material, incomplete information, or evidence outside the intended scope.
You May Be A Witness, Subject, Or Target
One of the first issues we try to determine is how federal prosecutors view the subpoena recipient. A person may be treated as a witness, a subject, or a target of the investigation.
A witness usually has information that could help the investigation. A subject is someone whose actions are being looked at as part of the investigation. A target is someone prosecutors think has strong evidence against them and might be charged with a crime.
These descriptions are not fixed legal protections. A person initially viewed as a witness can become a subject or target based on documents, testimony, statements to agents, or evidence obtained from other sources. For this reason, we do not assume that a person is safe simply because an agent or prosecutor informally refers to that person as a witness.
An attorney may contact the prosecutor to seek clarification regarding the client’s status. The prosecutor may provide an answer, but the government is not always required to reveal its full assessment or investigative strategy. We therefore evaluate the subpoena, surrounding circumstances, underlying relationships, and possible federal offenses rather than relying solely on a label.
Do Not Ignore A Federal Grand Jury Subpoena
A subpoena is a binding court command. Ignoring it, missing the appearance date, or refusing to produce responsive records without a valid legal basis can lead to contempt proceedings.
Federal Rule of Criminal Procedure 17(g) permits a federal court to hold a witness in contempt when the witness disobeys a subpoena without an adequate excuse. Contempt consequences may include coercive confinement, monetary sanctions, or criminal contempt proceedings, depending on the circumstances.
This does not mean that every demand must be accepted exactly as written. Counsel may contact the prosecutor to discuss the deadline, scope, production format, privilege concerns, or burden of compliance. In appropriate cases, counsel may seek to modify or quash the subpoena. The critical point is that objections should be addressed through lawful procedures. Simply refusing to respond can create a separate legal problem.
Preserve Every Potentially Responsive Record
After you get a subpoena, you must keep any records that might be needed. Deleting emails, destroying files, throwing away devices, changing spreadsheets, wiping a phone, editing entries, or asking someone else to hide evidence can lead to obstruction charges, even if you are never charged with a crime.
Under 18 U.S.C. § 1519, knowingly altering, destroying, concealing, falsifying, or making a false entry in a record with the intent to impede or influence a federal investigation can carry a sentence of up to 20 years in prison. The law can apply to conduct undertaken in relation to an existing federal matter or in contemplation of one.
Texas law also criminalizes certain acts involving evidence. Texas Penal Code § 37.09 prohibits a person who knows that an investigation or official proceeding is pending or in progress from altering, destroying, or concealing a record, document, or thing with the intent to impair its availability as evidence. Although a federal grand jury subpoena is governed by federal law, the same conduct may create separate state-law concerns when a related Texas investigation or proceeding exists.
We usually tell clients to stop any routine deletion and keep paper records, computers, cloud accounts, phones, accounting files, surveillance videos, and communications that might be covered by the subpoena. Keeping these records does not mean you have to hand them over right away. It just means you should secure the evidence while your lawyer figures out what needs to be shared by law.
Your Fifth Amendment Rights Still Matter
The Fifth Amendment protects a person from being compelled to provide testimonial evidence that may be self-incriminating. This protection can apply during federal grand jury testimony, but invoking it requires careful analysis.
A witness cannot normally refuse to appear merely because some questions may be incriminating. The witness generally must appear and assert the privilege in response to particular questions when a valid basis exists. A broad refusal to answer everything may not be legally sufficient.
Document subpoenas raise additional issues. Existing business records are not always protected merely because their contents are damaging. However, the act of identifying, collecting, authenticating, or producing records may sometimes have testimonial significance. The analysis depends on who owns the records, the type of entity involved, the capacity in which the person holds them, and what the production itself would communicate to the government.
Prosecutors may also seek an immunity order that compels testimony while restricting certain uses of that testimony. Immunity can have major consequences and should not be accepted or discussed casually. We evaluate whether the proposed protection is adequate and whether compelled testimony could lead investigators to independent evidence.
False Testimony Can Create A Separate Federal Charge
A witness must tell the truth before a federal grand jury. Knowingly making a materially false declaration can lead to prosecution under 18 U.S.C. § 1623. A conviction may carry up to five years in federal prison. The statute can also apply when someone knowingly uses documents or other information containing a materially false declaration in a grand jury proceeding.
Texas Penal Code § 37.02 separately defines perjury as making a false statement under oath or swearing to the truth of a previous false statement with intent to deceive and knowledge of the statement’s meaning. Texas Penal Code § 37.03 addresses aggravated perjury when the false statement is material and made during or in connection with an official proceeding. The federal statute is ordinarily the central concern during federal grand jury testimony, but false statements may create overlapping exposure when state proceedings or sworn Texas documents are also involved.
A witness should not guess, exaggerate, minimize, or adopt a prosecutor’s wording without understanding it. “I do not know” and “I do not remember” are proper answers when they are truthful. They become dangerous when used falsely to conceal known facts.
