Southern District of New York: The Sovereign District of Federal Law
The United States Attorney for the Southern District of New York (SDNY) serves as the chief federal law enforcement officer for eight contiguous counties in New York. Established by the Judiciary Act of 1789, this office is one of the most storied legal institutions in the United States, representing the federal government in both criminal and civil litigation.
Because its jurisdiction includes Manhattan—the preeminent financial hub of the nation—the office is often at the center of high-stakes legal battles. This unique position has earned the incumbent U.S. Attorney the nickname the "Sheriff of Wall Street."
