Investigations & White Collar Defense

Our Investigations and White Collar Defense team has considerable experience representing businesses and individuals in government investigations and enforcement actions as well as conducting internal investigations. Clients rely on us to be their trusted partners before or after the government initiates an enforcement action. Our talented team regularly advises and represents clients in healthcare fraud, government contract fraud, tax fraud, violations of the Anti-Kickback Statute, mail and wire fraud, money laundering, false statements, worksite enforcement actions, and government program fraud.

Clients also look to us to conduct internal investigations into complex and sensitive matters. With dozens of internal investigation under their belts, our team is adept at evaluating risk and implementing prevention and compliance measures. Importantly, we are able to draw on the knowledge and abilities of our experienced regulatory and industry professionals to develop comprehensive strategies that address not only the case at hand, but the public, media, and related consequences of enforcement actions.

  • trying well over 150 cases to verdict in federal and state courts

A Deepening Circuit Split: The Fifth Circuit Weighs in on Divide Over Deference Afforded to Sentencing Guidelines

In this article contributed to Law360, Jennifer Freel and Michael Murtha take a deep look into the effect of a recent Fifth Circuit en banc decision, noting that the amount of deference courts give the Guidelines is an issue for criminal practitioners to watch and something likely headed to the U.S. Supreme Court.

Major Case Update: Fifth Circuit Declines to Transform How Courts Apply Sentencing Guidelines

The Fifth Circuit Court of Appeals has issued its much-anticipated en banc decision United States v. Vargas, which tasked the Court with deciding how much deference courts should give commentary to the U.S. Sentencing Guidelines following the Supreme Court’s decision in Kisor v. Wilkie. In a fractured decision, the Fifth Circuit held that Kisor does not extend to the Guidelines; rather, Stinson v. United States continues to control without any alteration from Kisor. Thus, the current paradigm remains in the Fifth Circuit absent Supreme Court intervention: the Guidelines commentary is “authoritative unless it violates the Constitution or a federal statute, or is inconsistent with, or a plainly erroneous reading of, that guideline.”

For False Claims Act Cases, SCOTUS Says Courts Should Look at What Defendants Subjectively Knew at Time of Offense

The U.S. Supreme Court recently announced its ruling in United States Ex Rel Schutte v. SuperValu Inc., a case that will impact how corporations will defend themselves in False Claims Act (“FCA”) litigation. In a win for the government, the Court held that the knowledge element of the FCA concerns what a defendant knew at the time it submitted a claim, not what someone could have objectively known after-the-fact.

US Supreme Court Curtails Government Enforcement Power Under Three Federal Statutes, Reining in the DOJ

The U.S. Supreme Court recently decided three cases against the United States, with the Court rejecting the government’s attempt to prosecute or penalize private citizens under what the Court deemed to be overly expansive interpretations of statutes or regulations.
