(a)        In conducting an investigation, the Commission shall have access at all reasonable times to premises, records, documents, individuals, and other evidence or possible sources of evidence and may examine, record, and copy such materials and take and record the testimony or statements of such persons as are reasonably necessary for the furtherance of the investigation: Provided, however, that the Commission first complies with the provisions of the Fourth Amendment to the United States Constitution relating to unreasonable searches and seizures.

(b)        The Commission may issue subpoenas to compel access to or the production of such materials, or the appearance of such persons, and may issue interrogatories to a respondent, to the same extent and subject to the same limitations as would apply if the subpoenas or interrogatories were issued or served in aid of a civil action in the general court of justice.

(c)        Upon written application to the Commission, a respondent shall be entitled to the issuance of a reasonable number of subpoenas subject to the same limitations as subpoenas issued by the Commission.? Subpoenas issued at the request of a respondent shall show on their face the name and address of such respondent and shall state that they were issued at his request.

(d)       In case of contumacy or refusal to obey a subpoena, the Commission or the respondent may petition for its enforcement in the superior court for the district in which the person to whom the subpoena was addressed resides, was served, or transacts business. (1983, c. 522, s. 1; 1989 (Reg. Sess., 1990), c. 979, s. 1(3).)
