A lawsuit from a former GlaxoSmithKline employee alleging that he was fired for reporting concerns over the pharmaceutical company’s computer stability and security was properly dismissed, a federal appeals court has ruled.

The U.S. Court of Appeals for the Third Circuit upheld the lower court’s grant of summary judgment in favor of GSK in plaintiff Thomas Reilly’s case. Reilly brought claims under the Sarbanes-Oxley Act (SOX), which regulates the accuracy of corporate financial disclosures and prevents fraud.
