The definition of a tort, first and foremost, is a civil wrong that has caused unnecessary loss, grief or harm to another party. This creates a legal liability for the tortfeasor, or the person who has committed the tort. This definition applies to common law jurisdictions and can usually result in a lawsuit against the tortfeasor by the person who has suffered damages.
Torts have a common law in which there are different divisions of tort policy. This allows different situations to be handled separately and in accordance with their various needs. Tortious interference is also called intentional interference with contractual relationships, which is essentially the definition of this type of tort. It applies to both contractual relationships that may or may not be business related, and specifically business-related relationships that may not necessarily involve a contract.
Tortious interference occurs when the tortfeasor in this situation sets out with the express intention of causing harm or bringing damage to the business relationships or the contracts of a third party, often times through a different party. However, the tortfeasor could directly interfere with the targeted party, as well. Due to indirect responsibility in the case of involving another party, the tortfeasor is still the one responsible for tortious interference as long as they were aware of all business contracts and still proceeded to damage them even with this knowledge.
Tortfeasors can end up having to pay damages for the person who takes them to court and may end up facing more severe consequences as well. Due to this fact, businesses should be well aware of tortuous interference.
