Michael Ehline (Attorney at Law) gives expert video advice on: What is a tort of defamation?; What is 'libel'?; What is 'slander'? and more...

Absolute privilege is a situation, usually political, where in a statement is made in the course of a legislated proceeding. Where one congressman could say the most horrible things about another congressman and those statements will be deemed absolutely privileged, even though they're horrible and horrendous statements; that wouldn't be acceptable under any situation. Another example of an absolutely privileged statement could be a statement made in court, also known as litigation privilege. Those types of statements are never going to be subject to a defamation lawsuit.
