This book investigates the evolving relationship between national and state constitutional systems, challenging the traditional view of federalism as a structure of distinct, isolated legal domains. The authors, James A. Gardner and Jim Ross, curate a collection of essays that argue for a model of dual enforcement, where state and national norms are permanently and intimately linked. By examining the interplay between these systems, the text provides a framework for understanding how subnational constitutional law functions within the broader American legal landscape.

Legal scholars and practitioners view this collection as a significant contribution to the discourse on modern federalism. The text is frequently cited for its ability to bridge the gap between theoretical constitutional law and practical application in state courts.
