Cooper v. Aaron

After the Arkansas Governor used the National Guard to block Black students from a desegregated Little Rock school despite a federal court's Brown-based desegregation order, and after federal troops ultimately enforced desegregation, the Little Rock School Board, represented by Cooper (plaintiff), sued seeking to postpone the desegregation plan given the resulting turmoil; Aaron (defendant), representing Black students, opposed the delay, and the district court granted the requested relief before the court of appeals reversed.
