Tortious interference, also known as intentional interference with contractual relations, in the common law of torts, occurs when one person intentionally damages someone else's contractual or business relationships with a third party, causing economic harm. As an example, someone could use blackmail to induce a contractor into breaking a contract; they could threaten a supplier to prevent them from supplying goods or services to another party; or they could obstruct someone's ability to honor a contract with a client by deliberately refusing to deliver necessary goods.
A tort of negligent interference occurs when one party's negligence damages the contractual or business relationship between others, causing economic harm, such as by blocking a waterway or causing a blackout that prevents the utility company from being able to uphold its existing contracts with consumers.
Description
Tortious interference with contract rights Tortious interference with contract rights can occur when one party persuades another to breach its contract with a third party (e.g., using blackmail, threats, influence, etc.) or where someone knowingly interferes with a contractor's ability to perform his contractual obligations, preventing the client from receiving the services or goods promised (e.g., by refusing to deliver goods). The tortfeasor is the person who interferes with the contractual relationship between others. When a tortfeasor is aware of an existing contract and deliberately induces a breach by one of the contract holders, it is termed "tortious inducement of breach of contract".
Tortious interference with a business relationship Tortious interference with business relationships occurs where the tortfeasor intentionally acts to prevent someone from successfully establishing or maintaining business relationships with others. This tort may occur when one party knowingly takes an action that causes a second party not to enter into a business relationship with a third party that otherwise would probably have occurred. An example is when a tortfeasor offers to sell a property to someone below market value knowing they were in the final stages of a sale with a third party pending the upcoming settlement date to formalize the sale writing. Such conduct is termed "tortious interference with a business expectancy".
Tortious interference with an expected inheritance A person who, by tortious means, intentionally prevents another from receiving from a third person an inheritance or gift that he would otherwise have received is subject to liability to the other for loss of the inheritance or gift. (Believed to be the first claim for tortious interference with inheritance expectancy to withstand appeal in the State of Missouri.)
Negligent tortious interference The above situations are actionable only if someone with actual knowledge of, and intent to interfere with, an existing contract or expectancy between other parties, acts improperly with malicious intent and actually interferes with the contract/expectancy, causing economic harm. Historically, there has not been actionable cause if the interference was merely .See Robins Dry Dock & Repair Co. v. Flint, 175 U.S. 303 (1927) (lost profits held remote damage); Restatement (Second) of Torts § 766C (1979). See also Venhaus v. Shultz, 155 Cal. App. 4th 1072, 1079—1080, 66 Cal. Rptr. 3d 432 (2007) ("[W]e have been directed to no California authority, and have found none, for the trial court’s conclusion that the wrongful conduct must be intentional or willful. The defendant’s conduct must 'fall outside the boundaries of fair competition' ... but negligent misconduct or the violation of a statutory obligation suffice.") (internal citations omitted). However, some United States jurisdictions recognize such claims,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.) although many do not.See, e.g., Ramirez v. Selles, 784 P.2d 433, 436 (Or. 1989) ("Negligent injury to one person that harms another's contract or other economic relationship is not a tort, at least not unless some duty of defendant outside negligence law itself protects the injured interest of the plaintiff against negligent invasion"). A tort of negligent interference occurs when one party's negligence damages the contractual or business relationship between others, causing economic harm, such as by blocking a waterway or causing a blackout preventing the utility company from being able to uphold its existing contracts with consumers.
Case law An early (perhaps the earliest) instance of recognition of this tort occurred in Garret v Taylor, 79 Eng. Rep. 485 (K.B. 1620). In that case, the defendant drove customers away from the plaintiff's quarry by threatening them with mayhem and also threatening to "vex [them] with suits". The Court of King's Bench said that "the defendant threatened violence to the extent of committing an assaultIn English law, assault means causing a person to apprehend (i.e. fear) immediate unlawful violence, even if no violence occurs (if it does, the crime may be called battery). upon ... customers of the plaintiff ... whereupon 'they all desisted from buying'." The court therefore upheld a judgment for the plaintiff.
In a similar case, Tarleton v McGawley, 170 Eng. Rep. 153 (K.B. 1793), the defendant shot from its ship, Othello, off the coast of Africa upon natives while "contriving and maliciously intending to hinder and deter the natives from trading with" plaintiff's rival trading ship, Bannister. This action caused the natives (plaintiff's prospective customers) to flee the scene, depriving the plaintiff of their potential business. The King's Bench held the conduct actionable. The defendant claimed, by way of justification, that the local native ruler had given it an exclusive franchise to trade with his subjects, but the court rejected this defense.
The tort was described in the case of Keeble v Hickeringill (1707) 103 Eng. Rep. 1127, styled as a "trespass on the case". In that case, the defendant had used a shotgun to drive ducks away from a pond that the plaintiff had built for the purpose of capturing ducks. Thus, unlike the foregoing cases, here the actionable conduct was not directly driving the prospective customers away, but rather eliminating the subject matter of the prospective business. Although the ducks had not yet been captured, the Justice Holt wrote for the court that "where a violent or malicious act is done to a man's occupation, profession, or way of getting a livelihood, there an action lies in all cases." The court noted that the defendant would have the right to draw away ducks to a pond of his own, raising as a comparison a 1410 case in which the court deemed that no cause of action would lie where a schoolmaster opened a new school that drew students away from an old school.
The application of the above has since been modified in English law. In OBG v Allan 1 AC 1, wrongful interference, the unified theory which treated causing loss by unlawful means as an extension of the tort of inducing a breach of contract, was abandoned; inducing breach of contract and causing loss by unlawful means were two separate torts. Inducing a breach of contract was a tort of accessory liability, and an intention to cause a breach of contract was a necessary and sufficient requirement for liability; a person had to know that he was inducing a breach of contract and to intend to do so; that a conscious decision not to inquire into the existence of a fact could be treated as knowledge for the purposes of the tort; that a person who knowingly induced a breach of contract as a means to an end had the necessary intent even if he was not motivated by malice but had acted with the motive of securing an economic advantage for himself; that, however, a breach of contract which was neither an end in itself nor a means to an end but was merely a foreseeable consequence of a person's acts did not give rise to liability; and that there could be no secondary liability without primary liability, and therefore a person could not be liable for inducing a breach of contract unless there had in fact been a breach by the contracting party.
Acts against a third party counted as unlawful means only if they were actionable by that third party if he had suffered loss; that unlawful means consisted of acts intended to cause loss to the claimant by interfering with the freedom of a third party in a way which was unlawful as against that third party and which was intended to cause loss to the claimant, but did not include acts which might be unlawful against a third party but which did not affect his freedom to deal with the claimant. Strict liability for conversion applied only to an interest in chattels and not to chooses in action; this was too radical to impose liability for pure economic loss on receivers who had been appointed and had acted in good faith. This also left open the position where they breached the duty of good faith.
Typical examples Tortious interference of business – When false claims and accusations are made against a business or an individual's reputation in order to drive business away. Tortious interference of contract – When an individual uses "tort" (a wrongful act) to come between two parties' mutual contract.
Striking In the United Kingdom, a trade union encouraging or facilitating workers to take strike action commits tortious interference with the employees' contracts of employment, unless the action is conducted in accordance with Part V of the Trade Union and Labour Relations (Consolidation) Act 1992, as amended., Part V
Elements Although the specific elements required to prove a claim of tortious interference vary from one jurisdiction to another, they typically include the following:
The existence of a contractual relationship or beneficial business relationship between two parties. Knowledge of that relationship by a third party. Intent of the third party to induce a party to the relationship to breach the relationship. Lack of any privilege on the part of the third party to induce such a breach. The contractual relationship is breached. Damage to the party against whom the breach occurs.
