William F. Sullivan

Paul, Hastings, Janofsky & Walker LLP

Los Angeles, CA, USA


William Sullivan is a litigation partner who concentrates in corporate internal investigations, trial practice, and white-collar criminal defense, as well as complex civil litigation and securities enforcement and other regulatory actions.

Mr. Sullivan has substantial experience representing both companies and individuals in government and corporate investigations; in SEC enforcement actions; in grand jury, congressional, and independent counsel inquiries; in parallel proceedings and in courtroom jury trials; and in fraud, public corruption, criminal antitrust, and money laundering cases. His internal investigations work has involved the Foreign Corrupt Practices Act, USA PATRIOT Act compliance strategy, accounting improprieties and misleading financial disclosures, arms export control, and both civil and criminal antitrust issues.

Mr. Sullivan also has handled a variety of civil litigation matters, including antitrust, class action, securities regulation, environmental torts, intellectual property, broker-dealer regulation, product liability defense, arbitration, insurance defense, and a wide range of commercial contract disputes. In addition, he has advised on government contracts, federal tort claims, fraud, civil RICO, claims of privilege, false claims, and whistleblower litigation.

Examples of Mr. Sullivan’s recent and successful representations include officers of an international parcel tanker shipping enterprise in a criminal antitrust investigation involving allegations of price fixing, customer allocation, and continued criminal conduct following disclosure under the Department of Justice’s amnesty program; an international telecommunications company in a U.S. criminal antitrust investigation; a former vice chairman of Enron Corporation in parallel proceedings; a bank vice president in connection with the Allied Irish/Allfirst Financial foreign exchange trading scandal; the Special Committee on Accounting Matters of the Board of Directors of Global Crossing, Ltd. for the purpose of an internal investigation; several officers of Freddie Mac concerning allegations of accounting irregularities; a multinational pharmaceutical company regarding alleged violations of the International Traffic in Arms Regulations; a prominent private equity firm concerning an SEC/DOJ parallel probe; the former comptroller of U.S. Foods in the Royal Ahold accounting fraud case; the CEO of the Middle East’s largest Internet service provider involving a criminal investigation; a federal prosecutor accused of jury tampering; a pump manufacturing company in an arms export control case; several officers and directors of the former Riggs Bank regarding allegations of BSA violations and money laundering; and a petroleum and natural gas engineering company in a parallel DOJ/SEC FCPA investigation, in which he successfully persuaded both agencies to decline criminal and civil enforcement actions.

Because of the nature of Mr. Sullivan’s representations, a large number of his most successful matters have not resulted in public charges and remain confidential. Most recently, Mr. Sullivan obtained, after a month-long jury trial, an acquittal of all counts against Richard Convertino, the former federal prosecutor who obtained a criminal conviction in 2003 of a domestic Al Qaeda terrorist sleeper cell, but who himself was later charged with obstruction of justice, false statements, and conspiracy.

Mr. Sullivan previously served for more than 10 years as an assistant U.S. attorney for the District of Columbia. During his service, he tried high-profile cases involving first-degree murder, perjury, fraud, obstruction of justice, money laundering, conspiracy, narcotics, and criminal RICO charges. Mr. Sullivan was lead prosecutor in the first federal death penalty case to be tried in almost 50 years in the District of Columbia. He has won over 70 federal criminal jury cases, and has argued and prevailed in over 20 appeals in both New York and the District of Columbia.

Before becoming a federal prosecutor, Mr. Sullivan engaged in private practice as a litigator in New York City, and served in the Manhattan District Attorney’s Office.
