In basic business torts, the most common cause of action is for breach of fiduciary duty in state court. Generally, the elements of a breach of fiduciary duty claim are: (1) a fiduciary relationship must exist between the plaintiff and defendant; (2) the defendant must have breached his fiduciary duty to the plaintiff; and (3) the defendant's breach must result in injury to the plaintiff or benefit to the defendant. The biggest challenge normally is establishing whether or not one is a fiduciary. On this page you will find primary and secondary sources in support of how the fiduciary is defined. From here you can springboard into just about any business tort claim. Find below some of the most referenced case law and secondary sources to help jump start your research.

A leading case at common law is where a family placed their deceased father's best friend known as Uncle Key in a position of trust giving him rights to the land for the purpose of defending it from harassment. However, he took advantage of that trust and tricked the family into deeding over the property. The court held Uncle Key was in fact a fiduciary as he was placed in a position of trust.
It is interesting to note that one can also be held liable for aiding an abetting breach of fiduciary duties.

The Restatement (third) of agency will help familiarize you with why sometimes the company rather than the person is being sued. More often than not, it is because the company has more money than the employee.
