A person who wishes to take legal action for defamation must be able to prove that they have suffered, or could suffer, 'serious harm'. If a corporation is suing for defamation, it needs to prove that it has suffered 'serious financial loss' as a result of the publication of the allegedly defamatory matter.
Truth is an absolute defence to defamation. The defendant must prove that the defamatory statements were, in fact, true. For instance, if the statements concern the quality of goods or services, the defendant could provide independent testing or other evidence supporting the truth of the claims.
Truth is widely accepted as a complete defense to all defamation claims.
Truth is the first, and easiest, defense to a defamation claim. As discussed in the elements of defamation, the statement about you must have been false. If a Defendant can show that the statements were true, or even substantially true, then they could defeat a claim for defamation.
Truth, or substantial truth, is a complete defense to a claim of defamation.
All statements, written or spoken about you, which diminish your reputation in the eyes of right-thinking people, and which were made with that intention, will give you grounds for an action for damages for defamation.
The most common defenses to defamation are: 1) truth; 2) consent; 3) privilege; and 4) the statute of limitations. Perhaps the most distinct aspect of the defamation cause of action is that falsity is required.
