Sean Hecker

Sean Hecker is a partner at Kaplan Hecker & Fink LLP. He is an experienced trial lawyer whose practice focuses on white-collar criminal defense, government and internal investigations, complex civil litigation, and regulatory compliance.  

Sean is nationally recognized as a go-to lawyer for corruption and other white-collar criminal defense matters. He was recently named the 2020 White-Collar Crime/Investigations/Enforcement Attorney of the Year by Benchmark Litigation, which has also recognized him as among the Top 100 Trial Lawyers in the country. Sean was also recently inducted as a fellow into the American College of Trial Lawyers, one of North America’s premier legal associations. Chambers USA and Chambers Global have both ranked Sean as one of the leading trial lawyers in the country, describing him as “winning universal acclaim for his sophisticated practice.” Sean is also ranked by Chambers as “Band 1” among white-collar defense lawyers in New York, and is also nationally ranked by Chambers for his work on FCPA matters. Sources describe Sean to Chambers as “truly one of the most gifted trial lawyers,” calling him a “terrific,” “pragmatic and down-to-earth” lawyer, who is “trustworthy beyond any question” and whose “judgment is unfailingly good.” Clients note that “Sean is an excellent partner and a pleasure to work with. He is extremely knowledgeable about the law and applies it in a very practical way.” The Legal 500 US similarly rated Sean as a leading lawyer in corporate investigations and white-collar criminal defense, describing him as “thoughtful, commercial, and very experienced.” Sean has also recently been named a 2020 "Winning Litigator" by The National Law Journal, a 2019 White Collar MVP by Law360, a 2020 Best Lawyer in America in the field of Criminal Defense: White-Collar, a Leading Lawyer in America by the Lawdragon 500, a “New York Super Lawyer,” and a Thought Leader by Who’s Who Legal & Global Investigations Review. He is also listed by Benchmark Litigation as a “National Practice Area Star” and a “Local Litigation Star” in New York, and was named a “Client Service All-Star” by BTI Consulting Group in 2013.

Sean’s practice includes representing employees, officers, directors and corporations across various industries in grand jury and regulatory investigations, including those conducted by the DOJ, SEC, CFTC, FTC, IRS and federal and state banking regulators and state law enforcement agencies. He represents individuals on matters concerning alleged securities and commodities fraud, corruption (including the FCPA), accounting fraud, money laundering, tax fraud, and antitrust violations. He has tried numerous cases to juries in federal and state court. He also regularly advises clients on various legal and compliance issues.

In one particularly notable recent matter, Global Investigations Review honored Sean’s work in U.S. v. Bogucki by naming the case its 2019 “Most Important Court Case of the Year.” Serving as lead counsel to Robert Bogucki, who was accused of orchestrating an alleged $6 billion fraudulent scheme, Sean secured a rare acquittal at the conclusion of the Government’s case. Finding that no jury could reasonably convict Bogucki on the evidence presented, the presiding judge noted that he had never granted such an acquittal in his twenty years on the bench. Sean also recently successfully represented Cheikh Gadio, the former foreign minister of Senegal, in a complaint alleging FCPA violations. Sean was able to secure a government dismissal of the complaint against Mr. Gadio, as well as a non-prosecution agreement. Sean also maintains an active pro bono practice, including successfully securing a temporary restraining order in early 2019 that restored legal visitation rights at the Metropolitan Detention Center in Brooklyn, NY after they had been suspended in violation of the constitutional right to counsel.

Sean is a member of the Criminal Justice Act (CJA) Panel in the Southern District of New York, where he represents indigent federal criminal defendants. He is the President of the New York Council of Defense Lawyers, is a member of the board and past Chair of the Office of the Appellate Defender and the Federal Defenders of New York, Inc., and previously served as Chair of the New York City Bar Association's Mass Incarceration Task Force. 

Sean has authored numerous amicus briefs and publications concerning criminal justice issues and anti-corruption compliance.  His publications include “Between A Rock And A Hard Place: Anti-Corruption Compliance And Antitrust Law In Russia,” CEE Legal Matters (May, 2015); “DOJ Officials Encourage Companies to Cooperate Against Potentially Culpable Individuals,” “Just Blogs” section of Main Justice (October, 2014); “Conspiracy and the ‘Indefinite Payments’ Doctrine,” New York Law Journal (February, 2014); “Anti-Corruption Compliance in 2013: Post-Guidance and Signals for the Future,” Financial Fraud Law Report (February, 2014); Financial Fraud Law Report (November/December, 2013); Should FCPA ‘Territorial’ Jurisdiction Reach Extraterritorial Proportions?,” American Bar Association's International Law News (Winter, 2013); “The Bourke Conviction And Willful Blindness: Did The Second Circuit Get It Right?,” Financial Fraud Law Report (June, 2012); “Corrupt Intent, Relationship Building, And Quid Pro Quo Bribery: Recent Domestic Bribery Cases,” Financial Fraud Law Report (February, 2012).
