White Collar Defense and Regulation

Attorneys in the Chambers and Legal 500-ranked White Collar Defense & Regulation group represent corporations and individuals in connection with federal and state regulatory investigations, proceedings before self-regulatory organizations, corporate internal investigations, and  white collar criminal cases. Staffed by highly experienced former federal and state prosecutors and defense counsel, this group handles our clients’ most sensitive, complex, and time-sensitive regulatory, investigative, and criminal defense matters.

Our attorneys have represented clients in many of the major investigations of recent years. We have defended institutions and senior executives in proceedings involving the United States Department of Justice, the Securities and Exchange Commission, the New York State Attorney General, the NYSE, FINRA, the FSA, and the Federal Reserve, as well as in proceedings before the French financial market authority (AMF – Autorité des marchés financiers), the French banking authority (ACPR – Autorité de contrôle prudentiel et de résolution), and the French financial prosecutor (PNF – Parquet national financier). We have also handled major corporate internal investigations.

Our engagements have involved virtually every major industry, including securities and banking (including U.S., French, and foreign broker-dealers, mutual funds, hedge funds, investment banks, and commercial banks), accounting, aviation, insurance, pharmaceuticals, construction and real estate, e-commerce, energy, hospitality and travel services, and technology.
