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.

Winston Wins Unanimous Supreme Court Case Clarifying Securities Fraud Liability
Winston secured a unanimous victory in the U.S. Supreme Court for Macquarie Infrastructure Corp. in a federal securities class action that was filed after the announcement of the company’s 2017 financial results and 2018 dividend guidance caused US$2+B drop in market cap. The Court ruled that silence does not equal fraud, even if SEC regulations require disclosure. This decision resolves a longstanding disagreement among the lower courts about the scope of securities fraud liability under Rule 10b-5. It makes clear that a company cannot be liable under that provision for a pure omission of material information, even if SEC regulations required the information to be disclosed. This is particularly important for disclosures under Item 303 of SEC Regulation S-K, which requires management to make complex judgments about the likelihood of future events.

What Is the Foreign Corrupt Practices Act (FCPA)?
The Foreign Corrupt Practices Act (FCPA) is a federal statute prohibiting United States citizens and entities from engaging in corruption. It has two main elements: (1) anti-bribery provisions, forbidding the giving or offering of anything of value to a foreign government official for business and (2) accounting requirements, establishing mandatory practice guidelines for companies to maintain accurate records and internal controls. The FCPA is enforced by the Department of Justice (DOJ) and the Securities and Exchange Commission (SEC).
