In 1954 the contextualization of the equal protection clause would change forever. The Supreme Court itself recognized the gravity of the Brown v Board decision acknowledging that a split decision would be a threat to the role of the Supreme Court and even to the country. When
Earl Warren became Chief Justice in 1953,
Brown had already come before the Court. While Vinson was still Chief Justice, there had been a preliminary vote on the case at a conference of all nine justices. At that time, the Court had split, with a majority of the justices voting that school segregation did not violate the Equal Protection Clause. Warren, however, through persuasion and good-natured cajoling—he had been an extremely successful
Republican politician before joining the Court—was able to convince all eight associate justices to join his opinion declaring school segregation unconstitutional. In that opinion, Warren wrote: Warren discouraged other justices, such as
Robert H. Jackson, from publishing any concurring opinion; Jackson's draft, which emerged much later (in 1988), included this statement: "Constitutions are easier amended than social customs, and even the North never fully conformed its racial practices to its professions". The Court set the case for re-argument on the question of how to implement the decision. In
Brown II, decided in 1954, it was concluded that since the problems identified in the previous opinion were local, the solutions needed to be so as well. Thus the court devolved authority to local
school boards and to the
trial courts that had originally heard the cases. (
Brown was actually a consolidation of four different cases from four different states.) The trial courts and localities were told to desegregate with "all deliberate speed". Partly because of that enigmatic phrase, but mostly because of self-declared "
massive resistance" in the South to the desegregation decision,
integration did not begin in any significant way until the mid-1960s and then only to a small degree. In fact, much of the integration in the 1960s happened in response not to
Brown but to the
Civil Rights Act of 1964. The Supreme Court intervened a handful of times in the late 1950s and early 1960s, but its next major desegregation decision was not until
Green v. School Board of New Kent County (1968), in which Justice
William J. Brennan, writing for a unanimous Court, rejected a "freedom-of-choice" school plan as inadequate. This was a significant decision; freedom-of-choice plans had been very common responses to
Brown. Under these plans, parents could choose to send their children to either a formerly white or a formerly black school. Whites almost never opted to attend black-identified schools, however, and blacks rarely attended white-identified schools. In response to
Green, many Southern districts replaced freedom-of-choice with geographically based schooling plans; because
residential segregation was widespread, little integration was accomplished. In 1971, the Court in
Swann v. Charlotte-Mecklenburg Board of Education approved
busing as a remedy to segregation; three years later, though, in the case of
Milliken v. Bradley (1974), it set aside a lower court order that had required the busing of students
between districts, instead of merely
within a district.
Milliken basically ended the Supreme Court's major involvement in school desegregation; however, up through the 1990s many federal trial courts remained involved in school desegregation cases, many of which had begun in the 1950s and 1960s. The curtailment of busing in
Milliken v. Bradley is one of several reasons that have been cited to explain why equalized educational opportunity in the United States has fallen short of completion. In the view of various liberal scholars, the election of
Richard Nixon in 1968 meant that the executive branch was no longer behind the Court's constitutional commitments. Also, the Court itself decided in
San Antonio Independent School District v. Rodriguez (1973) that the Equal Protection Clause allows—but does not require—a state to provide equal educational funding to all students within the state. Moreover, the Court's decision in
Pierce v. Society of Sisters (1925) allowed families to opt out of public schools, despite "inequality in economic resources that made the option of private schools available to some and not to others", as
Martha Minow has put it. American public school systems, especially in large metropolitan areas, to a large extent are still
de facto segregated. Whether due to
Brown, or due to Congressional action, or due to societal change, the percentage of black students attending majority-black school districts decreased somewhat until the early 1980s, at which point that percentage began to increase. By the late 1990s, the percentage of black students in mostly minority school districts had returned to about what it was in the late 1960s. In
Parents Involved in Community Schools v. Seattle School District No. 1 (2007), the Court held that, if a school system became racially imbalanced due to social factors other than governmental racism, then the state is not as free to integrate schools as if the state had been at fault for the racial imbalance. This is especially evident in the charter school system where parents of students can pick which schools their children attend based on the amenities provided by that school and the needs of the child. It seems that race is a factor in the choice of charter school. ==Application to federal government==
