False Claims Act and Qui Tam

Defending Government Investigations

Our team has successfully defended clients dealing with government False Claims Act (FCA) investigations by resolving affirmative civil litigation matters before DOJ files suit, or convincing the government not to intervene in qui tam suits. Some recent examples of Jenner & Block FCA investigation successes include defending:

  • Multiple government contractors in a variety of industries;
  • A pharmaceutical distributor;
  • Multiple health insurance providers; and
  • Multiple surety companies.

We also helped a defense manufacturer who, during pre-sale diligence, discovered potential FCA issues. Our work included investigating the allegations, disclosing the facts, mitigating FCA risks, and resolving the matter with various government agencies to permit sale of the company.


Jenner & Block litigators have decades of experience litigating FCA matters. While very few FCA cases go to trial, our lawyers are ready to present aggressive and effective defenses through trial and, if needed, appeal. We have litigated FCA cases across multiple industries, including:

  • Pharmaceutical
  • Medical devices
  • Medical and surgical distribution
  • Defense article manufacturing
  • Construction
  • Services contracting
  • Aircraft manufacturing
  • Naval manufacturing
