A recent appellate court decision provides guidance on the limits of permissible discovery in a qui tam action filed under the False Claims Act (FCA). In United States ex rel. Duxbury v. Ortho Biotech Products, L.P., Case No. 12-2141 (1st Cir., Jun. 12, 2013), the United States Court of Appeals for the First Circuit held that the district court properly limited discovery in the relator’s qui tam action to only those time periods and regions of the country as to which the relator could be considered an “original source.” For more information on this court decision, please click here.
