In United States ex rel. Sorenson v. Wadsworth Brothers Construction Co., the U.S. Court of Appeals for the Tenth Circuit took up the dismissal of a complaint raising a so-called "false-certification" theory of liability under the False Claims Act. Relying on "the demanding materiality standard set out by the Supreme Court" in its 2016 Escobar decision, the appellate court affirmed the 10th Circuit Spotlightdistrict court's dismissal and emphasized the high bar that FCA plaintiffs face in pleading false-certification claims.
