The elements necessary to plead a cause of action for intentional interference with contractual relations, as follows:
(1) a valid contract between plaintiff and a third party;
(2) defendant’s knowledge of this contract;
(3) defendant’s intentional acts designed to induce a breach or disruption of the contractual relationship;
(4) actual breach or disruption of the contractual relationship; and
(5) resulting damage.
Pacific Gas & Electric Co. v. Bear Stearns & Co., 50 Cal. 3d 1118, 1126 (1990).
“Because interference with an existing contract receives greater solicitude than does interference with prospective economic advantage . . . , it is not necessary that the defendant’s conduct be wrongful apart from the interference with the contract itself.” Quelimane Co. v. Stewart Title Guaranty Co., 19 Cal. 4th 26, 55 (1998) (“Intentionally inducing or causing a breach of an existing contract is therefore a wrong in and of itself.”).
