Fraud
Fraud or fraudulent means conduct that involves a misrepresentation of material fact made with intent to deceive or a state of mind so reckless respecting consequences as to be the equivalent of intent, where there is justifiable reliance on the misrepresentation by the party deceived, inducing the party to act thereon, and where there is injury to the party deceived resulting from reliance on the misrepresentation. Fraud also may be established by a purposeful omission or failure to state a material fact, which omission or failure to state makes other statements misleading, and where the other elements of justifiable reliance and injury are established.
