Whether DeFunis's challenge to the law school's admissions policy remained a live Article III case or controversy after he had enrolled in the final quarter of law school.
Holding
No. The case was moot because DeFunis could complete his legal education and receive his degree regardless of how the Court resolved the constitutional question.
Reasoning
Article III permits federal courts to decide only disputes that can affect the legal rights of the parties before them. Although Washington law would preserve the appeal because of the public importance of its issues, mootness in the Supreme Court is a federal constitutional question.
DeFunis sought only an injunction requiring his admission to the law school, and he had already received that practical relief. Once he registered for the final quarter and the University assured the Court that it would honor his registration regardless of the merits, a decision could neither secure nor prevent his completion of law school.
Because DeFunis brought an individual action rather than a class action, no separate claim by similarly situated applicants remained before the Court. The controversy was no longer definite and concrete or one affecting parties with adverse legal interests.
The Court vacated the Washington Supreme Court's judgment and remanded for further proceedings that court considered appropriate, rather than allowing an unreviewed state-court merits decision to stand after the case became moot on review.
