Whether the plaintiffs had Article III standing and whether either dispute had become moot.
Holding
Yes. Parents Involved had standing to challenge Seattle's plan, and neither case was moot.
Reasoning
Parents Involved alleged that its members' children were forced to compete for high-school seats in a system that used race as a deciding factor. That unequal exposure to a race-based admissions process was itself a cognizable equal-protection injury, even though a particular child might ultimately obtain a desired assignment or choose an undersubscribed school.
Seattle's temporary suspension of its racial tiebreaker did not moot the controversy. The district continued to defend the program and gave no assurance that it would not resume using race if it prevailed; voluntary cessation moots a case only when recurrence is clearly impossible.
Jefferson County remained a live controversy because its racial guidelines applied at later grade levels, and Meredith's damages claim independently preserved a case or controversy even though Joshua later received a transfer.
