1.—(1) It is a defence to an action for defamation for the defendant to show that the imputation conveyed by the statement complained of is substantially true.
(2) Subsection (3) applies in an action for defamation if the statement complained of conveys two or more distinct imputations.
(3) If one or more of the imputations is not shown to be substantially true, the defence under this section does not fail if, having regard to the imputations which are shown to be substantially true, the imputations which are not shown to be substantially true do not seriously harm the plaintiff’s reputation.
(4) The common law defence of justification is abolished and, accordingly, section 5 of the Defamation Act (Northern Ireland) 1955 (justification) is repealed.
