Brown v. Board of Education
"Lum" was effectively overruled by the Court's decision in "Brown v. Board of Education" (1954), which outlawed segregation in public schools. However, an important part of the decision still stands. The power of the state to make racial distinctions in its school system, and to determine the race of its students, has not been overturned because it was not an issue in "Brown v. Board of Education".
