JM 9-11.151
It is the policy of the Department of Justice to advise a grand jury witness of his or her rights if such witness is a "target" or "subject" of a grand jury investigation.
A "target" is 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. An officer or employee of an organization which is a target is not automatically considered a target even if such officer's or employee's conduct contributed to the commission of the crime by the target organization. The same lack of automatic target status holds true for organizations which employ, or employed, an officer or employee who is a target.
A "subject" of an investigation is a person whose conduct is within the scope of the grand jury's investigation.
The Supreme Court declined to decide whether a grand jury witness must be warned of his or her Fifth Amendment privilege against compulsory self-incrimination before the witness's grand jury testimony can be used against the witness. See United States v. Washington, 431 U.S. 181, 186 and 190-191 (1977); United States v. Wong, 431 U.S. 174 (1977); United States v. Mandujano, 425 U.S. 564, 582 n. 7. (1976). InMandujano the Court took cognizance of the fact that Federal prosecutors customarily warn "targets" of their Fifth Amendment rights before grand jury questioning begins. Similarly, in Washington, the Court pointed to the fact that Fifth Amendment warnings were administered as negating "any possible compulsion to self-incrimination which might otherwise exist" in the grand jury setting. See Washington, at 188.
Notwithstanding the lack of a clear constitutional imperative, it is the policy of the Department that an "Advice of Rights" form be appended to all grand jury subpoenas to be served on any "target" or "subject" of an investigation. See advice of rights below.
In addition, these "warnings" should be given by the prosecutor on the record before the grand jury and the witness should be asked to affirm that the witness understands them.
Although the Court in Washington, supra, held that "targets" of the grand jury's investigation are entitled to no special warnings relative to their status as "potential defendant(s)," the Department of Justice continues its longstanding policy to advise witnesses who are known "targets" of the investigation that their conduct is being investigated for possible violation of Federal criminal law. This supplemental advice of status of the witness as a target should be repeated on the record when the target witness is advised of the matters discussed in the preceding paragraphs.
When a district court insists that the notice of rights not be appended to a grand jury subpoena, the advice of rights may be set forth in a separate letter and mailed to or handed to the witness when the subpoena is served.
Advice of Rights
Additional Advice to be Given to Targets: If the witness is a target, the above advice should also contain a supplemental warning that the witness's conduct is being investigated for possible violation of federal criminal law.
