§21-951.
   
   It shall be the duty of any judge of any court of record, upon the
   written request of the district attorney, or upon the sworn complaint
   of any other person, to issue subpoenas for any witness that may have
   knowledge of the violation of any provision of this act, and such
   judge shall have the power and it shall be his duty to compel such
   witness to appear before him and give testimony and produce any books
   or papers that will aid or assist in the prosecution of such
   investigation and inquiry into any violation of any provision of this
   act; but no person shall be prosecuted or subjected to any penalty or
   forfeiture for or on account of any transaction, matter or thing
   concerning which he may so testify or produce evidence. The testimony
   of each witness shall be reduced to writing by said judge, or by some
   person designated by him, and the same shall be signed by such
   witness. No person shall disclose any evidence so taken, nor disclose
   the name of any person so subpoenaed and examined, except when
   lawfully reguired to testify as a witness in relation thereto; and the
   unlawful disclosure, by any person, of any such evidence or of any
   matter or thing concerning such examination shall be a misdemeanor.
   Should said judge be unable to hold and conduct such inquiry and
   investigation for want of time, he may appoint a special judge who
   shall possess the qualifications and have the power in respect to such
   matters as the judge of the district court. Should any witness refuse
   to appear before such judge, in obedience to such subpoena, or refuse
   to produce any books or papers when lawfully required so to do, or
   having appeared, shall refuse to answer any proper question, or sign
   his testimony when so required, it shall be the duty of such judge to
   commit such person to the county jail until he shall consent to obey
   such orders and command of such judge in the premises, and in addition
   thereto such person may be punished, as for contempt of court, in
   accordance with the Constitution and laws of this state. The special
   judge appointed under the provisions of this section shall take the
   oath of the Constitution for state officers, and shall receive the
   compensation allowed by law for notaries public for taking depositions
   and be paid by the county in which such proceeding is had, upon the
   order of the judge who appointed him. When it is shown upon the taking
   of such testimony that there is probable cause to believe that any
   person has violated any provision of this act, the district attorney
   shall immediately prepare an information charging such person with
   such offense and file such information in some court of competent
   jurisdiction.
