As with most legal issues, I'm always amazed that people provide legal opinions without, perhaps, the necessary caveats -- for rarely is there a legal issue that is absolute.
For example, the notion of defamation, libel or slander may vary (and does vary) significantly by jurisdiction. In the United States, pretty much alone in the world, the First Amendment of the Federal Constitution (along with State Constitutional provisions) significantly impacts this area of law, unlike other common law jurisdictions, such as the UK.
In the USofA, unlike the rest of the common law countries, "Truth is an absolute defense" to a defamation claim and has been since the late 1700s. The modern interpretation of that old rule is even broader in that the statements just need to be "substantially true" for the absolute defense to be sustained.
This has nothing to do with the Sullivan rule regarding public figures and the "absence of malice." (By the way, the movie of that title is wonderful and in large part based on real events.) IF the statements published ARE true, then malice is irrelevant, it is only when statements are false that malice, with regards to a public figure, becomes important. (Another "by the way" and this one is aimed directly at Thal, the NYT was (and is) a corporation and was provided protection by the Supreme Court under the First Amendment in the Sullivan case just as any natural person would have been protected. Every justice/judge just assumed that legal, as well as natural, persons are protected by the Bill of Rights. But back to our regularly scheduled programming.)
John, IF something that is published IS true, it may NOT be "libelous" nor "defaming" (at least in the vast majority of USofA legal jurisdictions). There may be some other legal action but it would be hard to square such with the First Amdt -- ESPECIALLY if the publication was done within the context of "journalism."
