You as members of the grand jury do solemnly swear (or affirm) that you will diligently inquire, and true presentment make, of all offenses given you in charge, or otherwise brought to your knowledge, committed or triable within this county; that you will keep secret the state's counsel, the other jurors' and your own; that you will present no person from hatred, malice, or ill will, nor leave any unpresented through fear, favor, or affection, or for any reward, or the promise or hope thereof, but that you will present the truth, the whole truth, and nothing but the truth, according to the best of your skill and understanding. So help you God.
Tenn. R. Crim. P. 6
Advisory Commission Comment.
This rule substantially reflects existing law, including the provision allowing concurrent grand juries. The voting power of the grand jury foreperson is made explicit. The judge's charge to the grand jury "shall instruct it concerning its powers and duties and expound the law to it as the judge shall deem proper."
Witness immunity provided in Rule 6(j)(5) and (6) requires comment. The first provision provides that: "A person refusing to testify before the grand jury may be compelled to testify by the court on motion of the district attorney general and upon a grant of immunity from prosecution for any offense in relation to which the person has been ordered to testify." This rule is triggered by the refusal of a witness to testify before a grand jury.
The second says: "No witness shall be indicted for any offense in relation to which the district attorney general has compelled the witness to testify before the grand jury." Note that the rule says "the district attorney general has compelled the witness to testify" rather than "has testified."
Rule 6(j)(5) carries the subtitle "Compelling Witnesses to Testify." It provides a tool whereby one can be required to give up an asserted Fifth Amendment right, but not until the witness is explicitly given a grant of immunity from prosecution (not just indictment, so one already indicted could be so compelled) for any offense in relation to which the witness has been ordered to testify.
Rule 6(j)(6) is subtitled "Immunity of Certain Witnesses from Prosecution" and expressly limits the immunity to indictment for offenses about which the witness was compelled to testify by the district attorney general. This rule grants immunity only to those witnesses compelled to testify by the district attorney general, or the district attorney general's assistant or agent, by virtue of subpoena or order of the judge. The commission does not desire to depart from the scope of the immunity given under T.C.A. §40-1623 [now repealed], and the cases decided thereunder.
The commission views the immunity rules as being limited strictly to the instances addressed by them. Rule 6(j)(5) is triggered only where there is a Fifth Amendment or other refusal of a witness to testify and an explicit court order to do so; Rule 6(j)(6) is triggered only when the district attorney general compels the witness to testify.
T.C.A. §§ 40-12-104 - 40-12-107 provide a procedure designed to give citizens free access to the local grand jury. Under this statute, persons applying to testify before the grand jury are not immune from prosecution based upon or related to their testimony, except under express grant of immunity by the grand jury. The statute expressly states that it is supplemental to existing law.
