Tort of injurious falsehood -
The tort of injurious falsehood is sort of like defamation against businesses or Corporations, as you can not "defame" a Corporation and nor do they have a ready remedy in defamation if you do, it does not mean there is no common law remedey available to them against a person who does make malicious false statements against them.
Most typically this tort is available when a business competitor makes false claims about the goods, services or business that is directed to the customers or would be customers of the business but this equally applied against individuals, say in online reviews or social media, where it causes damage to the business or causes customers to go elsewhere.
