New Challenges To Judicial Federalism, James A. Gardner Jun 2024

New Challenges To Judicial Federalism, James A. Gardner

Journal Articles

The theory of judicial federalism holds that state constitutions are jurisprudentially independent from the U.S. Constitution, and that state supreme courts consequently may, and often should, interpret state constitutions differently from how the U.S. Supreme Court interprets the federal Constitution. As the U.S. Supreme Court increasingly turns back to the states important decisions of constitutional policy, such as the scope of reproductive rights or the nature and content of limitations on partisan gerrymandering, state constitutional law looms ever larger as a potential ground for resolution of these issues.

The conditions for a revival of judicial federalism today, however, are far …
