Minn. Stat. § 46.35: INTERPRETATIONS.

The commissioner of commerce may upon request from an interested party give an interpretive opinion in connection with the administration of chapters 45 to 56. No penalty provision in these chapters or of any other chapter to which chapters 45 to 56 may refer applies to any act done or not done in conformity with a written interpretive opinion of the commissioner, notwithstanding that the written interpretive opinion may, after the act or omission, be amended or rescinded or be determined by judicial or other authority to be invalid for any reason.
