A three-judge United States District Court for the District of Maryland found the practice was in violation of the Interstate Commerce Act but remanded the case on February 18, 1946 back to the ICC. On March 1, 1946, the company announced a change in their rules for dining cars. Ten tables would be exclusively for white passengers and one table of four seats would be exclusively for black passengers with a curtain drawn between this and the other tables. White passengers could no longer be seated at the black table. This satisfied the ICC and the federal court. However, Henderson was not satisfied and, with the backing of the National Association for the Advancement of Colored People (NAACP) appealed the decision to the Supreme Court.
