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.
Truth is widely accepted as a complete defense to all defamation claims.
The publishing of a statement which lowers the individual or the company in the estimation of right thinking members of society generally. Broadly, the test is whether a statement would cause one to think less of the person or company to whom it refers.
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.
The test for defamation is whether, in the opinion of a reasonable person with ordinary intelligence, the words have the tendency to undermine, subvert, or impair a person's good name, reputation or esteem in the community. A two staged enquiry is adopted in this regard.
Truth, or substantial truth, is a complete defense to a claim of defamation.
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.
Generally, to prove defamation, you must show that a false statement was made, about you, to third parties, and which caused you damage. Once you have evaluated your case, and determined that you can satisfy these elements, you can then proceed with pursuing your matter.
