SDCL § 10-1-28 — Administration of oaths to witnesses--Proceedings on refusal of witness to testify or produce evidence--Compensation of witnesses and officers serving summons--False testimony as perjury

The secretary of revenue, in any matter under investigation or consideration, may administer oaths to witnesses. If any witness fails to obey any summons to appear before the secretary, refuses to testify or answer any question, or fails to produce records, books, papers, or documents if required so to do, such failure or refusal shall be reported to the attorney general who shall institute proceedings in the proper circuit court to compel obedience to any summons or order of the secretary. Officers who serve summonses or subpoenas and witnesses attending shall receive like compensation as officers and witnesses in the circuit court. Such compensation shall be paid by the county for whose benefit the investigation is made, upon certificate of the secretary of revenue.
Any person who testifies falsely in any matter under consideration by the secretary of revenue in an investigation as provided in this section is guilty of perjury.
