The Supreme Court ruled that the exclusion of African Americans from jury service solely because of their race violated the Equal Protection Clause of the Fourteenth Amendment. The Court held that the state could not discriminate against African Americans in the selection of jurors and that all citizens, regardless of race, were entitled to the equal protection of the laws. This ruling was a significant step forward in the fight for civil rights and paved the way for future Supreme Court decisions that would strike down other forms of racial discrimination.
