Special rules apply in the case of statements made in the press concerning public figures, which can be used as a defense. A series of court rulings led by New York Times Co. v. Sullivan, 376 U.S. 254 (1964) established that for a public official (or other legitimate public figure) to win a libel case, the statement must have been published knowing it to be false or with reckless disregard to its truth, (also known as actual malice).[15]
Under United States law, libel generally requires five key elements. The plaintiff must prove that the information was published, the plaintiff was directly or indirectly identified, the remarks were defamatory towards the plaintiff's reputation, the published information is false, and that the defendant is at fault.
The Associated Press estimates that 95% of libel cases involving news stories do not arise from high-profile news stories, but "run of the mill" local stories like news coverage of local criminal investigations or trials, or business profiles. Media liability insurance is available to newspapers to cover potential damage awards from libel lawsuits.
One function of the letter from her counsel is to provide notice. Publication after notice is then "know it to be false."
To the extent several websites, most notably liberal Alaska blogger Shannyn Moore, are now claiming as "fact" that Governor Palin resigned because she is "under federal investigation" for embezzlement or other criminal wrongdoing, we will be exploring legal options this week to address such defamation. This is to provide notice to Ms. Moore, and those who re-publish the defamation, such as Huffington Post, MSNBC, the New York Times and The Washington Post, that the Palins will not allow them to propagate defamatory material without answering to this in a court of law.
I'll post the complete letter separately, if I don't see it eleswhere on FR.
