What are the implications of a federal district court's refusal to dismiss a state law claim?

Because we conclude that there was no violation of the plaintiffs' constitutional rights, we do not reach the issues of qualified immunity and municipal liability. Furthermore, given the eventual dismissal of all of plaintiffs' federal claims, we find that the district court acted well within its discretion in declining to assert supplemental jurisdiction over plaintiffs' state-law claim. See Marcus v. AT & T Corp., 138 F.3d 46, 57 (2d Cir.1998) ("In general, where the federal claims are dismissed before trial, the state claims should be dismissed as well.").
