Practice Area
Government Program Fraud, False Claims Act & Qui Tam Litigation
Investigations and litigation involving alleged fraud against the government pose a significant and growing threat to organizations and individuals across all industries that engage directly or indirectly in business with federal, state, and/or local governments. The government makes aggressive use of its extensive criminal and civil investigatory powers to root out alleged fraud and abuse implicating government funds, including one of its most powerful civil enforcement tools—the federal False Claims Act (FCA)—and similar state false claims statutes.
