An actionable civil conspiracy is a combination of two or more persons who, each having the intent and knowledge of the other’s intent, accomplish by concert an unlawful purpose, or accomplish a lawful purpose by unlawful means, which results in damage to the plaintiff. See Brown v. Birman Managed Care, Inc., 42 S.W.3d 62, 67 (Tenn.2001) (citing Dale v. Thomas H. Temple Co., 186 Tenn. 69, 87, 208 S.W.2d 344, 353 (1948)). Upon a finding of conspiracy, each conspirator is liable for the damages resulting from the wrongful acts of all co-conspirators in carrying out the common scheme. Id.
It has long been accepted in Tennessee that a corporation is capable of extra-corporate conspiracy; that is, a corporation becomes vicariously liable for the conduct of its agents who conspire with other corporations or with outside third persons. See, e.g., Standard Oil Co. v. State, 117 Tenn. 618, 665, 100 S.W. 705, 716-17 (1907).
Trau-Med of America, Inc. v. Allstate Ins. Co. 71 S.W.3d 691, 703 (Tenn.,2002)
We have very recently discussed the common law action of conspiracy to defraud. See Chenault v. Walker, 36 S.W.3d 45 (Tenn.2001) (upholding the validity of the conspiracy theory of personal jurisdiction). This tort is defined as a “combination between two or more persons to accomplish by concert an unlawful purpose, or to accomplish a purpose not in itself unlawful by unlawful means.” Id. (quoting Dale v. Thomas H. Temple Co., 186 Tenn. 69, 90, 208 S.W.2d 344, 353 (1948)); see also Huckeby v. Spangler, 521 S.W.2d 568, 573 (Tenn.1975); Braswell v.. Carothers, 863 S.W.2d 722, 727 (Tenn.Ct.App.1993); Kirksey v. Overton Pub, Inc., 739 S.W.2d 230, 236 (Tenn.Ct.App.1987). Each conspirator must have the intent to accomplish this common purpose, and each must know of the other’s intent. Dale, 186 Tenn. at 90, 208 S.W.2d at 353-54. The agreement “need not be formal, the understanding may be a tacit one, and it is not essential that each conspirator have knowledge of the details of the conspiracy.” Id. Finally, “it is [a] basic principle that each conspirator is responsible for everything done by his confederate which the execution of the common design makes probable as a consequence”; in other words, each conspirator is liable for the damage caused by the other. Id. 186 Tenn. at 90-91, 208 S.W.2d at 354; accord Huckeby, 521 S.W.2d at 573-74.
Brown v. Birman Managed Care, Inc. 42 S.W.3d 62, 67 (Tenn.,2001)
The elements of a cause of action for civil conspiracy are: (1) a common design between two or more persons, (2) to accomplish by concerted action an unlawful purpose, or a lawful purpose by unlawful means, (3) an overt act in furtherance of the conspiracy, and (4) resulting injury. Morgan v. Brush Wellman, Inc., 165 F.Supp.2d 704, 720 (E.D.Tenn.2001). Conspiracy claims must be pled with some degree of specificity. McGee v. Best, 106 S.W.3d 48, 64 (Tenn.Ct.App.2002) (citing Haynes v. Harris, No. 01A01-9810-CV-00518, 1999 WL 317946, at *2 (Tenn.Ct.App.1999)) (citations omitted). Conclusory allegations, however, unsupported by material facts will not be sufficient to state such a claim. Id.
