Government Contracts False Claims Act Defense

Our False Claims Act experience and track record successfully defending companies in the government contracts and logistics space is unmatched. We have defended allegations focused on issues including fraud in the inducement; failure to meet contractual or regulatory requirements; pricing errors, overcharging or improper timekeeping; kickbacks and gratuities/Anti-Kickback Act violations; defective products/services; defective pricing/truthful cost or Pricing Data Act (formerly TINA) violations; and management of government property. Our FCA attorneys are familiar with the Federal Acquisition Regulation and applicable regulatory regimes, but when needed, we work closely with attorneys in the firm's top-ranked Government Contracts practice to provide comprehensive and practical legal advice. Our FCA team also handles parallel proceedings in administrative proceedings so our clients do not need two sets of outside counsel.
