Minnesota Statutes Civil Procedure (Ch. 540-552) § 544.043. Defamation by television and radio; defense

The owner, licensee, or operator of a visual or sound radio broadcasting station or network of stations, or any agent or employee of any such owner, licensee, or operator, is not liable for damages for any defamatory statement published or uttered in or as a part of a visual or sound radio broadcast, by any one other than such owner, licensee, or operator, or agent or employee thereof, if such owner, licensee, operator, or such agent or employee, shows an exercise of due care to prevent the publication or utterance of the statement in that broadcast. Provided, however, the exercise of due care shall be construed to include a bona fide compliance with any federal law or the regulation of any federal regulatory agency.
