Historical Society of the New York Courts Trustees Dennis E. Glazer and Hon. Albert M. Rosenblatt trace New York’s relationship with slavery from the early days of the colony to the climate of the nation leading up to the Civil War. The episode culminates with an investigation into the Lemmon Slave Case itself. Affirmed by the Court of Appeals in 1860, the Lemmon Slave Case illustrates how NYS law was ahead of federal in finding that slaves brought into the State were not property. This went against the Supreme Court’s Dred Scott decision, decided three years earlier.
