party to recover its legal costs from the plaintiff. Defences There are a variety of defences to defamation claims in common law jurisdictions. The two most fundamental defences arise from the doctrine in common law jurisdictions that only a false statement of fact (as opposed to opinion) can be defamatory. This doctrine gives rise to two separate but related defences: opinion and truth. Statements of opinion cannot be regarded as defamatory as they are inherently non-falsifiable. Where a statement has been shown to be one of fact rather than opinion, the most common defence in common law jurisdictions is that of truth. Proving the truth of an allegedly defamatory statement is always a valid defence. Where a statement is partially true, certain jurisdictions in the Commonwealth have provided by statute that the defence "shall not fail by reason only that the truth of every charge is not proved if the words not proved to be true do not materially injure the claimant’s reputation having regard to the truth of the remaining charges". Similarly, the American doctrine of substantial truth provides that a statement is not defamatory if it has "slight inaccuracies of expression" but is otherwise true. Since a statement can only be defamatory if it harms another person's reputation, another defence tied to the ability of a statement to be defamatory is to demonstrate that, regardless of whether the statement is true or is a statement of fact, it does not actually harm someone's reputation. Other defences recognised in one or more common law jurisdictions include: Privilege: A circumstance that justifies or excuses an act that would otherwise constitute a tort on the ground that it stemmed from a recognised interest of social importance, provides a complete bar and answer to a defamation suit, though conditions may have to be met before this protection is granted. While some privileges have long been recognised, courts may create a new privilege for particular circumstances – privilege as an affirmative defence is a potentially ever-evolving doctrine. Such newly created or circumstantially recognised privileges are referred to as residual justification privileges. There are two types of privilege in common law jurisdictions: Absolute privilege has the effect that a statement cannot be sued on as defamatory, even if it were made maliciously; a typical example is evidence given in court (although this may give rise to different claims, such as an action for malicious
