Both California contract law and tort law allow for legal action when a third party wrongfully interferes with a contract or ongoing business relationship. Tortious interference refers to the action of a third party who causes harm to an ongoing business arrangement.Our business litigation lawyers and attorneys have helped numerous businesses who have become victims of interference with contractual and business relations. When a person or business intentionally damages a business relationship or a contract you have with another business that caused or may cause economic harm. If a third party unfairly interferes with a business contract or relationship and causes damage, a tortious interference claim may be a viable option. California courts have long recognized causes of action for tortious interference with contract and tortious interference with prospective economic advantage. This blog talks about the Cal jury instructions and what a Plaintiff has to prove to meet their "burden of proof" in a civil case. If the defendant was a competitor regarding the business involved in the contract, his interference with the contract may not be improper. An example may include a competitor breaking the law to gain an unfair advantage causing severe harm to yourself or your business. However, that case dealt with whether a party can be found liable for conspiracy to interfere with their own contract.
