Dodd-Frank’s whistleblower incentive provisions have generated plenty of excitement for plaintiffs lawyers and teeth-gnashing among corporations and their counsel—even if we’re all still waiting for the first award. In the meantime, a trickle of court opinions is offering a preview of years of likely litigation over the scope of whistleblower protection under the law.
