The tort of interference with prospective economic advantage protects the same interest in stable economic relationships as does the tort of interference with contract, though interference with prospective advantage does not require proof of a legally binding contract. The elements for intentional interference with prospective economic advantage are: (1) an economic relationship between the plaintiff and some third party, with the probability of future economic benefit to the plaintiff, (2) the defendant’s knowledge of the relationship, (3) intentional acts on the part of the defendant designed to disrupt the relationship, (4) actual disruption of the relationship, and (5) economic harm to the plaintiff proximately caused by the acts of the defendant.
