The scope of whistleblower protection under the Dodd-Frank Wall Street Reform and Consumer Protection Act remains murky for now, as the U.S. Court of Appeals for the Second Circuit on Thursday declined to address an important question about the law.

The court handed defendant Siemens AG a victory on Thursday by affirming the dismissal of a whistleblower anti-retaliation suit. But it sidestepped the question of whether whistleblower protections apply to employees who are fired after reporting problems internally but before taking complaints to the Securities and Exchange Commission.
