The commission or its authorized agents may examine any books, papers, records or other data bearing upon the correctness of any report required to be made under the provisions of this article, and may require the attendance of any person and take his testimony with respect to any such matter, and shall have power to administer an oath to such person. If any person summoned as a witness shall fail to obey any summons to appear before the commission or its authorized agent, or shall refuse to testify or answer any material question or to produce any book, record, paper or other data when required to do so, such failure or refusal shall be reported to the attorney general, the district attorney or county attorney, who shall thereupon institute proceedings in the chancery court of the county where such witness resides to compel obedience to any summons of the commission or its authorized agent.
