Libel is a written or published false statement that harms someone's reputation.
It is a form of defamation that occurs when a false, damaging statement about a person is communicated in a permanent form, such as in a newspaper, online post, or letter. In a court case, the plaintiff must prove the statement was false, published to a third party, and caused harm to their reputation, while the defendant may raise defenses like truth or fair comment.
For someone facing a libel case, it matters because they must show the statement was false and caused real harm to win; for a defendant, proving the statement was true or a protected opinion can defeat the claim. The case often involves complex questions about who said what, whether the statement was fact or opinion, and how much damage was done.
A common misunderstanding is that any offensive or negative statement is libel, but only false statements of fact that damage reputation qualify, not mere insults or opinions. Also, simply reposting someone else's false statement can still make you liable for libel.
