Sean Haran

Partner 212 335 2033

A trial lawyer and adviser, Sean represents individuals and companies that are under investigation by the government or that have been charged in criminal or regulatory proceedings. He also assists organizations in conducting internal investigations.

Sean has handled numerous investigations for publicly traded and privately held companies in response to government inquiries, adverse media reports and whistleblower allegations. Whether reporting to boards of directors, special committees or members of senior management, Sean has helped clients weigh the risks and rewards of self-reporting to the government and determine and implement appropriate remedial measures. When the government is already involved in a matter, he has helped position his clients for the most advantageous resolution.

Sean has persuaded prosecutors in numerous instances to close criminal and regulatory inquiries without bringing charges.  These include, for example:

Representing the former Brooklyn District Attorney in a federal grand jury investigation into the potential misuse of state asset forfeiture funds;
the US Attorney’s Office for the Eastern District of New York closed the inquiry without charges.

Representing the former General Counsel of the Port Authority of New York and New Jersey in parallel SEC and state grand jury investigations into
allegations of federal securities fraud and violations of New York’s Martin Act; the SEC and the New York County District Attorney’s Office each closed
their inquiries without filing charges.

Representing a well-known internet company in a consumer protection investigation by the Office of the New York Attorney General;
the NYAG closed the inquiry without charges.

Sean has defended dozens of individuals in response to criminal and regulatory charges and in civil matters, including at trial in state and federal court and in SEC administrative proceedings. He has defended investment advisers, traders, senior corporate executives, lawyers and other business professionals in matters ranging from securities and accounting fraud, insider trading, tax fraud, market manipulation, pay-to-play, antitrust, commercial bribery and theft-of-honest services frauds, corruption, trade-secrets cases, index-rate manipulation, money laundering, sanctions and OFAC violations, and conflicts-of-interest matters.

Before reentering private practice in 2009, Sean served as an Assistant U.S. Attorney in the Eastern District of New York for eight years, where he helped lead the office’s Business & Securities Fraud Section as its Deputy Chief. He successfully tried numerous cases and won various commendations, including the “True American Hero Award” for his work against violent gangs. He also served as an adjunct professor at Columbia Law School, where he taught federal criminal practice.
