Utah Code § 45-2-5
No person, firm, or corporation owning or operating a radio or television broadcasting station or network of stations shall be liable under the laws of libel, slander or defamation on account of having made its broadcasting facilities or network available to any person, whether a candidate for public office or any other person, or on account of having originated or broadcast a program for discussion of controversial or any other subjects, in the absence of proof of actual malice on the part of such owner or operator. In no event, however, shall any such owner or operator be held liable for any damages for any defamatory statement uttered over the facilities of such station or network by or on behalf of any candidate for public office.
