In order to obtain such injunctive relief it shall not be necessary to allege or prove that an adequate remedy at law does not exist.
No person shall be excused from attending and testifying or from producing books, papers, contracts, agreements, and documents in any case or proceedings instituted or brought under the provisions of sections 325D.02 to 325D.072, or in obedience to a subpoena, in any such case or proceedings, on the ground or for the reason that the testimony or evidence, documentary or otherwise, required of the person may tend to criminate or subject the person to a penalty or forfeiture; 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 the person may testify, or produce evidence, documentary or otherwise, in any such case or proceedings, or in obedience to a subpoena, in any such case or proceedings.
