Explanation:

Henderson v. United States (1950) eliminated the tables assigned to African American people and the curtain that divided them on dining cars, it did not outlawed segregation.

Elmer W. Henderson was an African American who was travelling first class from Washington to Atlanta on the Southern Railway. He went to have dinner on the dining car, where the two tables near the kitchen were reserved for African Americans, and had curtains that divided them from the rest of the people, the law stated that when no African American passenger arrived the two tables were available for white people.

When Henderson arrived there was one white person dining in one of the tables and the steward refused to assign him a table, and asked if she could serve him at his seat. Henderson refused and the steward told him she would call him when the table was available, but he was never called nor served, so he filled a complaint to the Interstate Commission that was dismissed, so the US Supreme Court agreed it was a violation of principles.
