Illinois recognizes two types of torts to remedy an actor’s interference with a party’s business relationships: tortious interference with contract and tortious interference with prospective economic advantage.[1] Whether interference with an at-will contract is more appropriately remedied under the interference-with-contract tort or the interference-with-prospective-economic-advantage tort is a distinction with a significant difference. Determining which tort applies may be critical to the outcome of a dispute because the two torts provide different levels of protection against a third party’s interference.[2] Contractual relationships enjoy greater protection from interference than relationships based on the mere possibility of future economic advantage.[3]
