Daves v. Dallas County, Texas

Issue: (1) Whether Younger v. Harris and its progeny require federal courts to abstain from adjudicating petitioners' constitutional challenges to respondents' pretrial detention of many thousands of presumptively innocent people; and (2) whether, under this court's precedent, legislation enacted during a lawsuit renders the asserted claims moot if the legislation does not provide the relief sought in the litigation, such that the courts could still provide the plaintiff with effectual relief.
