In a closely watched case, the U.S. Supreme Court on Monday began considering arguments over whistleblower lawsuits filed under the federal False Claims Act, USA Today reports. At issue in the case is whether such lawsuits should be blocked if whistleblowers bring their claim based on public information available in a state or local report. Currently, False Claims Act suits are only barred if the claims were gleaned from federal public disclosures such as congressional reports, audits or investigations.
