The U.S. Supreme Court on Wednesday struck down a lawsuit that would have broadened protections for corporate whistleblowers. The case was brought forth by an executive at a data processing company who was fired after submitting possible security law violations to senior management. He did not report the violations to the S.E.C.

The ruling: All nine justices unanimously voted in favor of Digital Reality Trust Inc., noting that the 2010 Dodd-Frank Act protects whistleblowers if they report misconduct to the S.E.C., but the executive failed to do so.
