Paul A. Diller

Professor of Law, Director of the Certificate Program in Law & Government

Paul Diller’s professional work focuses on the legal structures that constrain or empower local policymaking. Recent scholarship examines the growing disconnect between urban policy preferences and those of state legislatures in many states. His other recent work addresses the unique potential of cities to spur regulatory change, particularly with respect to protecting the public health. Diller has directed Willamette Law's Certificate Program in Law and Government since 2014.

Diller is an active participant in the Oregon legislative process, advocating for legislation that promotes the public health and economic fairness. For several years, he worked on strategies to combat youth obesity with a leading nonprofit organization. In 2014, he co-authored a widely cited amicus brief in defense of the legality of New York City’s sugar-sweetened-beverage portion-cap rule.

Diller clerked for Chief Judge Edward R. Becker of the U.S. Court of Appeals for the Third Circuit after law school. From 2002-05, he was a trial attorney in the Civil Division of the U.S. Department of Justice in Washington, D.C., where he litigated constitutional, employment discrimination and Freedom-of-Information-Act cases, among others. In his spare time, he enjoys playing and watching baseball, skiing, drinking coffee, and spending time with his family.

In Fall 2016, Diller teaches:  

  • Law 255: Administrative Law
  • Law 304: State and Local Government Law
