In Astoria Indus. of Iowa, Inc. v. SNF, Inc., 223 S.W.3d 616, 633 (Tex. App.--Fort Worth 2007, pet. denied), in an appeal from a summary judgment, the Fort Worth court of appeals rejected a contention that a claim for tortious interference with prospective relations could not apply to a complaint that business was taken from an existing customer. The Court concluded that tortious interference with prospective business relations includes tortious interference with continuing business relationships. Id. The court then proceeded to review the summary-judgment evidence concerning the defendant's alleged interference with the plaintiff's existing customer, including whether there was no evidence that the defendant engaged in independently tortious conduct. See id. at 633-37.
