Whistleblower lawsuits are also known as “qui tam” claims. “Qui tam” is an old Latin term derived from the phrase “he who sues on behalf of the King as well as for himself.” In other words, it describes a type of case brought for the government but also for a private individual’s personal benefit.
A “whistleblower” is an individual who reports fraud against the government. In today’s legal system, qui tam is a legal term that describes a case brought under the False Claims Act by a private individual on behalf of the federal government.
