Counsel for the appellant admitted that they could not find a case quite in point in support of the validity in law of the defence which they wished to add, but they contended that it rested on a sound principle. They adopted as their own a statement in the recent text-book of Mr. Spencer Bower K.C., at p. 134, in which the learned author places the following defences in the category of "defeasible immunity," which corresponds with the "qualified privilege" of other writers, namely: "Where the defendant published the defamatory matter in assertion or defence of his, or his employer's or principal's or client's property, rights, or interests against any infringement or demand or claim by the plaintiff, or in defence of his, or his employer's, principal's, or client's reputation or character against any charge, imputation, or attack made by the plaintiff," &c. Counsel contended that it was open to the appellant to plead that the publication sued on was in defence not only of the appellant's character, but of his proprietary interest, against an attack upon his character and an infringement of that interest, both being contained in the respondent's article in reply to which the alleged libel was published. It may be questioned whether the learned author used the word "infringement" in the sense which Mr. McArthur attributed to it. However that may be, counsel urged that to the extent of reasonable necessity for its purpose, every published statement made with the object of fairly protecting some interest of the writer is the subject of qualified privilege. He cited the case of Blackham v. Pugh[1] (approved in Baker v. Carrick[2]), in which Tindal C.J. said[3]: - "In any point of view, this case appears to me to fall within the range of that principle by which a communication made, by a person immediately concerned in interest, in the subject matter to which it relates, for the purpose of protecting his own interest, in the full belief that the communication is true, and without any malicious motive, is held to be excused from responsibility in an action for a libel." In the same case Erle J. said[4]: - "The defendant contends that he is within that class of the cases where the presumption of malice is rebutted by the occasion, which is grounded on consideration of the private interest of the party publishing: and I think that he is, because he believed, with reasonable cause, that the communication was required in prudence to protect his rights." In Coward v. Wellington[5] Littledale J. said: - "If a man bonâ fide writes a letter in his own defence, and for the defence and protection of his interests and rights, and is not actuated by any malice, that letter is privileged, although it may impute dishonesty to another; but in such cases, malice may either be proved by the letter itself, or by other evidence." A leading case on this subject, also cited, is Laughton v. Bishop of Sodor and Man[6]; but it does not, nor did any other case cited, deal with the position which arises when the attack repelled by the publication complained of not merely asperses the character of the defendant, but involves injury or probable injury to his property, as, for instance, a newspaper. It may be true that a newspaper cannot be libelled in the ordinary sense; but false statements maliciously made, that is, made intentionally and without just cause or excuse, "where they are calculated in the ordinary course of things to produce, and where they do produce, actual damage" to the plaintiff personally, or to his business give him a cause of action on the case (Ratcliffe v. Evans[7], per Bowen L.J.). Then, is not the owner of a business, such as a newspaper, entitled to repel at once a false and malicious attack upon it, even where actual damage has not yet been done, provided that the attack is in the ordinary course of things calculated to produce that result? And, if so, is there any difference where the thing attacked is correctly described in his pleading as his proprietary interest in a newspaper? This I take to be the real question in this case. It comes before us purely as one of principle; for there is no authority in direct support of the appellant's argument, and certainly there is none the other way, either. True, it is not strictly within the principle laid down as to qualified privilege by Erle C.J. in the passage so often cited from Whiteley v. Adams[8]. But neither is the protection which the law allows to the honest repulse by defamatory matter, believed to be true, of a public attack on a defendant's character. That, I think, stands on the same ground as the reasonably necessary return of physical blows in self-defence against aggression, and the degree of protection given is limited in a closely analogous way. But property also may be reasonably defended against forcible attack, nor is the response in either case confined within the narrowest limits of necessity. In this view the matter rests upon as sound a ground as the right of a defendant to repel by counter-publication a libellous attack upon his own character. In such cases there is no question of community of interest, or of corresponding interest, as in other cases of privilege. The defendant is allowed to defend himself in the same field in which the plaintiff has assailed him - if the attack is through the press, then again the press may be used in answer: See Laughton v. Bishop of Sodor and Man[9]. The aggressor cannot, as Mr. Odgers puts it (5th ed., at p. 292), "subsequently come to the Court as plaintiff, to complain that he has had the worst of the fray." But in such cases the defendant must see to it that his retort, if vigorous, is fair; that is, that it does not go beyond the occasion.
