The Passenger Cases and the commerce clause: immigrants, blacks, and states' rights in antebellum America

University of Kentucky Law Library

"In 1849 Chief Justice Taney's Court delivered a 5-4 decision on the legal status of immigrants and free blacks under the federal commerce power. The closely divided decision, further emphasized by the fact there were eight opinions, played a part in the increasingly contested politics over growing immigration, and the controversies about fugitive slaves and the western expansion of slavery that resulted in the Compromise of 1850."
