In Carroll v. President and Comm'rs of Princess Anne County, 393 U.S. 175, 89 S.Ct. 347, 21 L.Ed.2d 325 (1968), a white supremacist organization sought review of an ex parte injunction issued against a rally. Although the occasion had long since passed, and the 10-day injunction had expired, the Supreme Court concluded that the suit deserved adjudication on the merits because 'it appears that the decision of the (state court upholding the injunction) continues to play a substantial role in the response of officials to (the organization's) activities.' In the Carroll case, the Supreme Court concluded that "consideration (of the issues raised) ought not to be, as they might be, defeated by short term orders, capable of repetition, yet evading review ."
