In the individual context, a tort occurs when one person cause harm to another that is the result of a breach of ordinary or reasonable care owed to that other person. Being artificial persons, businesses can be liable for torts as well: either for wrongs done against individuals, or for wrongs committed toward another business, known appropriately as business torts.
Most of the time business torts are the result of one business taking free market competition too far. Unfair competition is one species of business tort; so is wrongful interference, which can be defined as one business deliberately attempting to harm the contractual relationship of another business, or to try to supplant that contractual connection. Wrongful interference is more than simply competing with another company for the same contract, which is legitimate. It frequently consists of a business attempting to sabotage the contractual relations of a competitor.
