The issue presented in this case is whether the Orange County Florida public school system is now unitary. The answer depends on a review of the posture of the system in light of two controlling decisions of the Supreme Court.*fn1 In Green v. County School Board of New Kent County, 1968, 391 U.S. 430, 88 S. Ct. 1689, 20 L. Ed. 2d 716, the mechanics of what must be done to bring about a unitary system were outlined. They were stated in terms of eliminating the racial identification of the schools in a dual system in six particulars: composition of student bodies, faculty, staff, transportation, extracurricular activities, and facilities. 391 U.S. at 435, 88 S. Ct. It was such dual systems, organized and operated by the states acting through local school boards and school officials, which were held unconstitutional in Brown v. Board of Education, 1954, 347 U.S. 483, 74 S. Ct. 686, 98 L. Ed. 873 (Brown I), and which were ordered abolished in Brown v. Board of Education, 1955, 349 U.S. 294, 75 S. Ct. 753, 99 L. Ed. 1083 (Brown II).
