See Union Oil Co. v. Oppen, 501 F.2d 558 (9th Cir. 1974) (holding negligent interference with prospective advantage actionable when risk of harm was foreseeable); In re Kinsman Transit Co., 388 F.2d 821 (2d Cir. 1968) (dictum: stating that negligent interference with contract should receive same legal treatment as other negligent acts); J'Aire Corp. v. Gregory, 24 Cal. 3d 799, 804, 157 Cal. Rptr. 407, 598 P.2d 60 (1979) ("Where a special relationship exists between the parties, a plaintiff may recover for loss of expected economic advantage through the negligent performance of a contract although the parties were not in contractual privity") (emphasis supplied); Settimo Associates v. Environ Systems, Inc., 14 Cal. App. 4th 842, 845, 17 Cal. Rptr. 2d 757 (1993) ("The tort of intentional or negligent interference with prospective economic advantage imposes liability for improper methods of disrupting or diverting the business relationship of another which fall outside the boundaries of fair competition") (emphasis supplied) (internal citation omitted). There used to be California authority that no cause of action exists for negligent interference with contractual relations. See Fifield Manor v. Finston, 54 Cal. 2d 632, 636—637, 7 Cal. Rptr. 377, 354 P.2d 1073 (1960). But the J'Aire decision, supra, appears to have overruled Fifield. Nevertheless, however illogical it may seem, it is arguable that California does not recognize a tort of negligent interference with contractual relations, but does recognize a tort of negligent interference with prospective economic advantage. See Young v. Fluorotronics, S.D. Calif. 2010). (This is comparable to recognizing manslaughter but decriminalizing murder.)
