Is there a cause of action for negligent interference with contract?

With respect to the Mirtorabis' claim for negligent interference with contract, no such cause of action exists. "[T]he courts have quite consistently refused to recognize a cause of action based on negligent, as opposed to intentional, conduct which interferes with the performance of a contract between third parties or renders its performance more expensive or burdensome." (Fifield Manor v. Finston (1960) 54 Cal.2d 632, 636.) The claim fails as a matter of law.
