For the traditional and hydra-headed phrase “cause of action”* the Federal Rules of Civil Procedure have substituted the word “claim.” It is used to denote the aggregate of operative facts which give rise to a right enforceable in the courts. See 1 Moore, Federal Practice, pp. 3, 145-150, 605; Clark, Code Pleading, §§ 19, 70. Under Rule 10(b) a separation of claims into separate counts is mandatory only when necessary to facilitate clear presentation. See Moore, supra, p. 607. Strictly, therefore, the issues presented are (1) whether the complaint and amended complaint allege but a single claim or cause of action and (2), if more than one claim is alleged, whether a separation of the claims is required to facilitate clear presentation of the matters set forth.
The original complaint alleged in substance that the defendants conspired to ruin the plaintiff’s business of producing ballets, and in furtherance of the conspiracy committed tortious acts by circulating defamatory statements and inducing employees of plaintiff to break their contracts and enter the employ of its competitor, Ballet Theatre, Inc. The amended complaint is framed along identical lines but amplifies the details of the acts done by the defendants in carrying out the conspiracy and shows that tortious conduct by one of them, Hurok Attractions, Inc., was also a breach of its contract to manage performances of the plaintiff’s ballet company on certain tours. The ad damnum was largely increased. It is the defendants’ contention that where a. complaint alleges a conspiracy pursuant to which actionable torts are committed, then the cause or causes of action are the independent torts and not the conspiracy. This view was adopted by the district court.
We agree that where conduct is tortious in itself allegations that it was committed pursuant to a conspiracy add nothing to the complaint, although conduct otherwise innocent may sometimes become actionable if done in concert. Green v. Davies, 182 N.Y. 499, 505, 75 N.E. 536, 3 Ann.Cas. 310; Lewis Invisible Stitch Mach. Co. v. Columbia Mfg. Co., 2 Cir., 80 F.2d 862, 864; A. L. I. Torts, §§ 765, 775. But we cannot agree that the claim for relief set out in plaintiff’s original and amended complaints was one “for conspiracy.” The cause of action alleged is the intentional destruction of plaintiff’s business without justifiable excuse. All the acts of defendants are alleged to have been directed to this end. The charge could have been laid against Ballet Theatre, Inc., alone. Except in so far as non-tortious conduct may be rendered actionable by concert, allegations of conspiracy neither add to nor detract from the wrong of intentional and unjustifiable destruction of a person’s business. They are important only to show that the wrong was committed jointly by the defendants so that the acts of one may be imputed to the others because of their common purpose and intent. Brackett v. Griswold, 112 N.Y. 454, 466, 20 N.E. 376; Bob v. Hecksher, 235 App.Div. 82, 83, 256 N.Y.S. 126. Recognition of the cause of action under discussion goes back at least to the early case of Keeble v. Hickeringill, 11 East 574n. The philosophy underlying it has been brilliantly expounded in Oliver Wendell Holmes’ famous essay, “Privilege, Malice and Intent,” 8 Harv.L.Rev. 1. It has been adopted in the American Law Institute’s Restatement of the Law of Torts, Division Nine, “Interference with Business Relations.” We do not doubt that the law of New York also recognizes the tort of wrongful interference with one’s business. See Opera on Tour, Inc. v. Weber, 285 N.Y. 348, 34 N.E.2d 349, 136 A.L.R. 267; American Guild of Musical Artists v. Petrillo, 286 N.Y. 226, 231, 36 N.E.2d 123. In the latter case the court referred to the former as an application of “the broad doctrine that harm intentionally done is actionable if not justified.”
The fact that in pleading his claim the plaintiff has charged the defendants with accomplishing the harm by acts which viewed independently might themselves be deemed torts does not necessarily mean that he has alleged several causes of action which must be stated in separate counts. In Oliver v. Perkins, 92 Mich. 304, 52 N.W. 609, the plaintiff’s declaration alleged a series of acts which the defendants classified as constituting respectively a breach of contract, a trespass, and a slander, but the court held that a series of wrongful acts, all aimed at a single result and contributing to the injury complained of, to wit, the destruction of one’s business, credit and reputation, may be counted upon, not severally but collectively, as producing
