The clerk of the state grand jury, upon request of the Attorney General or his designee, shall issue subpoenas, or subpoenas duces tecum to compel individuals, documents or other materials to be brought from anywhere in the state or another state to a state grand jury. In addition, a state grand jury may proceed in the same manner as is provided for by law in relation to the issuance of subpoenas and subpoenas duces tecum; however, the provisions of such law shall not be considered a limitation upon this section, but shall be supplemental thereto. The subpoenas and subpoenas duces tecum may be for investigative purposes and for the retention of documents or other materials so subpoenaed for proper criminal proceedings. Any investigator employed by the Attorney General or any law enforcement officer with appropriate jurisdiction is empowered to serve such subpoenas and subpoenas duces tecum and receive such documents and other materials for return to a state grand jury. Any person violating a subpoena or subpoena duces tecum issued pursuant to this chapter, or who fails to fully answer all questions put to him before proceedings of the state grand jury whenever the response thereto is not privileged or otherwise protected by law, including the granting of immunity as authorized by this chapter, or any other law, may be punished by the impaneling judge for contempt provided the response is not privileged or otherwise protected by law. The Attorney General or his designee may petition the impaneling judge to compel compliance by the person alleged to have committed the violation or who has failed to answer. If the impaneling judge considers compliance is warranted, he may order compliance and may punish the individual for contempt, as provided in Section 9-1-17, where the compliance does not occur. The clerk of the state grand jury may also issue subpoenas and subpoenas duces tecum to compel individuals, documents or other materials to be brought from anywhere in the state to the trial of any indictment returned by a state grand jury or the trial of any civil forfeiture action arising out of an investigation conducted by a state grand jury.
