Argued on October 5, 1964, and decided on December 14, 1964, the case of Katzenbach v. McClung established the principle that a restaurant—even one that operated only in one state—was bound under the terms of the Civil Rights Act of 1964 to provide dine-in services to African American clients. The restaurant in question, Ollie’s Barbecue, was owned by Ollie McClung and was in Birmingham, Alabama. Ollie McClung argued that Congress could not enforce the Civil Rights Act against him because his restaurant was a small business that was not directly involved in interstate commerce, so the federal government had no authority in the matter.
