RS 603 - Investigations by commissioner; attendance of witnesses; depositions A. The commissioner may investigate any facts, conditions, practices, or matters which he may find necessary or proper in order to determine whether any person has violated or is about to violate any provision of this Part or any rule, regulation, or order thereunder, or to aid in the enforcement of the provisions of this Part or in prescribing rules or regulations hereunder, or in obtaining information to serve as a basis for recommending further legislation to the legislature. The commissioner may permit any person to file with him a statement in writing, under oath or otherwise, as he shall determine, as to any or all facts and circumstances concerning a matter which may be the subject of investigation.  B. For the purpose of any investigation or any other proceeding under this Part, the commissioner or any officer or employee of the State Department of Conservation designated by him is empowered to administer oaths and affirmations, subpoena witnesses, compel their attendance, take evidence, and require the production of any books, papers, correspondence, memoranda, contracts, agreements, or other records which the commissioner finds relevant or material to the inquiry. Witnesses summoned by the commissioner to appear before him shall be paid the same fees and mileage that are paid witnesses in the courts of the state.  C. In case of contumacy by, or refusal to obey a subpoena issued to, any person, the commissioner may invoke the aid of any court of competent jurisdiction in requiring the attendance and testimony of witnesses and the production of books, papers, correspondence, memoranda, contracts, agreements, and other records. Such court may issue an order requiring such person to appear before the commissioner or officer or employee of the State Department of Conservation designated by the commissioner, there to produce records, if so ordered, or to give testimony touching the matter under investigation or in question; and any failure to obey such order of the court may be punished by such court as a contempt thereof. All process in any such case may be served in the judicial district whereof such person is an inhabitant or wherever he may be found or may be doing business. Any person who willfully shall fail or refuse to attend and testify or to answer any lawful inquiry or to produce books, papers, correspondence, memoranda, contracts, agreements, or other records, if in his or its power so to do, in obedience to the subpoena of the commissioner, shall be guilty of a misdemeanor and upon conviction shall be subject to a fine of not more than $1,000 or to imprisonment for a term of not more than one year, or both.  D. The testimony of any witness may be taken at the instance of a party, in any proceeding or investigation pending before the commissioner, by deposition at any time after the proceeding is at issue. The commissioner may also order testimony to be taken by deposition in any proceeding or investigation pending before him at any stage of such proceeding or investigation. Such depositions may be taken before any person authorized to administer oaths not being of counsel or attorney to either of the parties, nor interested in the proceeding or investigation. Reasonable notice must first be given in writing by the party or his attorney proposing to take such deposition to the opposite party or his attorney of record, as either may be nearest, which notice shall state the name of the witness and the time and place of the taking of his deposition. Any person may be compelled to appear and depose, and to produce documentary evidence, in the same manner as witnesses may be compelled to appear and testify and produce documentary evidence before the commissioner, as hereinbefore provided. Such testimony shall be reduced to writing by the person taking deposition, or under his direction, and shall, after it has been reduced to writing, be subscribed by the deponent.  E. If a witness whose testimony may be desired to be taken by deposition be in a foreign country, the deposition may be taken before an officer or person designated by the commissioner, or agreed upon by the parties by stipulation in writing to be filed with the commissioner. All depositions must be promptly filed with the commissioner.  F. Witnesses whose depositions are taken as authorized in this Part, and the person or officer taking the same, shall be entitled to the same fees as are paid for like services in the courts of the state.  G. No person shall be excused from attending and testifying or from producing books, papers, correspondence, memoranda, contracts, agreements, or other records and documents before the commissioner, or in obedience to the subpoena of the commissioner or any officer or employee of the State Department of Conservation designated by him, or in any cause or proceeding instituted by the commissioner, on the ground that the testimony or evidence, documentary or otherwise, required of him may tend to incriminate him or subject him to a penalty or forfeiture; but no individual shall be prosecuted or subject to any penalty or forfeiture for or on account of any transaction, matter, or thing concerning which he is compelled to testify or produce evidence, documentary or otherwise, after having claimed his privilege against self-incrimination, except that such individual so testifying shall not be exempt from prosecution and punishment for perjury committed in so testifying.
