Proving defamation in Oregon involves several factors. One factor is whether the individual defamed is a private individual or a public figure. A claim of defamation involving a private individual usually has the same elements no matter the jurisdiction:
The primary defense to a claim of defamation is that the statement is true. A true statement that is derogatory is not a defamatory statement. The same applies with a statement that involves an opinion. An opinion is not considered a statement alleging an objective fact but is rather a personal observation. If a defendant claims he or she was expressing a personal opinion and not a statement of fact regarding the plaintiff, he or she can avoid liability. Privilege also avoids liability for defamation.
The best defense is obtaining the services of a skilled litigator to defend against charges. Talk with an attorney about defamation defenses in Oregon.
