We previously reported on the Supreme Court’s opinion earlier this year in Tyson Foods v. Bouaphakeo, a non-FCA case that upheld the use of statistical sampling to establish liability in a Fair Labor Standards Act suit, but which offered important narrowing limitations that we argued were applicable to FCA cases (see here).  Relying in part on Tyson Foods, a district court recently refused to allow a relator to use extrapolation to establish FCA liability, finding that extrapolation was inappropriate in a case based on claims of medical necessity.  See United States ex rel. Wall v. Vista Hospice Care, Inc., No. 07-cv-00604 (N.D. Tex. June 20, 2016).
