The McClungs own Ollie’s Barbecue, a restaurant located a few blocks from the interstate highway in Birmingham, Alabama, with dining accommodations for whites only and a take-out service for blacks. In the year preceding the passage of the Civil Rights Act of 1964, the restaurant had purchased a substantial portion of the food it served from outside the state. The restaurant has refused to serve blacks since its original opening in 1927 and asserts that if it were required to serve blacks it would lose much of its business. The McClungs sought a declaratory judgment to render unconstitutional the application of the Civil Rights Act to their restaurant because their admitted racial discrimination did not restrict or significantly impede interstate commerce. What should the decision be?
