Sidley’s White Collar group is recognized for its significant experience in all aspects of corporate criminal defense and enforcement-related litigation, including internal investigations, client representation in grand jury investigations, management of parallel criminal and civil proceedings, extraditions and counseling on foreign criminal investigations and advice on voluntary disclosure and compliance issues, such as issues under the Sarbanes-Oxley Act.


Our lawyers aggressively defend corporations and their executives, public officials and other individuals in cases involving allegations of securities fraud, bribery, perjury and false statements, tax fraud, antitrust violations, healthcare fraud, false claims, FDA violations, immigration fraud and environmental crimes. We are able to work efficiently in many industries and areas by using our own knowledge and abilities from our experienced regulatory and industry professionals to develop comprehensive strategies that address all of the legal and factual defenses, as well as the public, media and other collateral consequences, of the case. 

Our corporate criminal defense lawyers provide critical advice at every stage of an investigation or case. Some of our greatest successes have never become public because victory was achieved by convincing prosecutors not to pursue charges against our clients. Other cases have involved some of the most publicized cases of recent decades, including representing members of Congress and executive branch officials, as well as other targets, in all the major independent counsel investigations, including Watergate, Iran-Contra and Whitewater. When trial is the best option, we have a range of experienced trial counsel with records of success, including a victory in one of the few criminal cases against a major U.S. corporation, United States v. Tyson Foods, Inc., a National Law Journal “defense verdict of the year.”
