Pharmaceutical giant AstraZeneca has been released from a whistleblower suit in federal court in Philadelphia.

Because the relator in the qui tam action didn’t satisfy the standard for being an original source with direct and independent knowledge of the company’s alleged violation of the False Claims Act and because essentially identical allegations have already been made in other lawsuits and in newspaper reports, the claims can’t survive the public disclosure bar, U.S. District Judge J. William Ditter Jr. of the Eastern District of Pennsylvania has ruled.
