The binding legal principles established are: (1) In motion proceedings, parties define the nature and scope of the dispute through their pleadings and affidavits, and a court may not grant relief mero motu that was not sought by the parties, as this violates the adversarial nature of civil litigation and may prejudice a party's right to a fair hearing under section 34 of the Constitution; (2) An interdict to restrain the publication of allegedly defamatory statements is granted infrequently because it impinges on the constitutionally protected right to freedom of speech, and the party alleging injury is ordinarily left to their remedy of damages; (3) Where a defendant in defamation proceedings establishes a factual foundation for a defence of justification (truth and public benefit) or fair comment, the court is not entitled to disregard that defence in motion proceedings, and the matter must proceed to trial where the truth can be determined; (4) To obtain an interim interdict pending a defamation action, the applicant must establish: (a) a prima facie right, (b) a well-grounded apprehension of irreparable harm, (c) that the balance of convenience favours the interdict, and (d) the absence of another satisfactory remedy; (5) An interdict is a prospective remedy concerned with present and future conduct, not past invasions of rights, and requires evidence of an intention or likelihood to repeat the conduct; (6) Where damages would adequately vindicate the right to reputation if defamation is later established, an anticipatory interdict will seldom be necessary or appropriate.
