Wisconsin Statutes Trade Regulations (Ch. 125 to 139) § 133.11. Investigatory proceeding

(1) Whenever the attorney general files with any supplemental court commissioner a statement that the attorney general has reason to believe and does believe that a violation of this chapter has occurred, the commissioner shall issue a subpoena or a subpoena requiring the production of materials as requested by the department of justice. Mileage or witness fees are not required to be paid in advance but claims for such mileage and fees duly verified and approved by the department of justice shall be audited and paid out of the state treasury and charged to the appropriation provided by s. 20.455(1)(d), and shall be at the same rates as witnesses in the circuit court.

(2) The testimony shall be taken by a stenographic reporter, transcribed, read to or by the witness and subscribed by the witness, unless the parties represented shall stipulate, upon the record, that the reading of the transcript of the testimony to or by the witness and the signature thereto are waived, and that the transcript may be used with like force and effect as if read and subscribed by the witness. The attendance of the witness for the purpose of reading and subscribing the transcript may be compelled in the same manner that attendance to be examined may be compelled.

(3) The supplemental court commissioner shall be entitled to the fees as provided in s. 814.68(1). All such fees and all other costs and expenses incident to the inquiry shall be paid out of the appropriation provided by s. 20.455(1)(d).
