The most popular definition of tort credited to Salmond is "a civil wrong for which the remedy is a common law action for unliquidated damages, and which is not exclusively the breach of a contract, or the breach of a trust or other merely equitable obligation."
Business or economic torts are therefore wrongful acts committed against business entities, whether intentional or negligently or recklessly, that occasion harm (or capable of occasioning harm in the future) by way of financial loss.
I must point out the fact that your question appears academic. If you are not a lawyer or law student, you may not be able to understand the key words in this definition. And you may not also be able to categorize a wrongful conduct as civil tort or criminal conduct. This is because business torts are not criminal offenses, although some business torts also may be charged as such (including restraint of trade in some cases).
If you want this definition to be further expounded or you want to know if a particular set of facts or circumstances can be categorized as business tort and how such legal issues can be addressed or remedied, send me a direct message. Stay fine!
