[email protected]. Federal Courts, Overbreadth, and Vagueness: Guiding Principles for Constitutional Challenges to Uninterpreted State Statutes Stuart Buck* and Mark L. Rienzi** I. INTRODUCTION When a state statute is challenged in federal court as unconstitutionally overbroad or vague, the federal court is caught between two fundamental principles of constitutional law. On the one hand, federal courts have been instructed numerous times that they should invalidate a state statute only when there is no other choice. The Supreme Court has noted that it is a "cardinal principle" of statutory interpretation that a federal court must accept any plausible interpretation such that a state statute need not be invalidated. Moreover, the doctrines of abstention, certification, and severance all exist in order to show deference to a state's power to interpret its own laws and to allow as much of a state law to survive as possible.
