Paul A. Diller

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

Professor Paul Diller's professional work focuses on the legal structures, including federalism and gerrymandering, that constrain or empower local policymaking. Diller’s work on state preemption of local power has been widely cited; his recent work argues that some forms of preemption are more democratically legitimate than others. In September 2017, Diller authored an amicus brief on behalf of several municipal organizations and local government law professors in a Supreme Court case challenging gerrymandering of state legislative districts. 

Diller graduated from the University of Pennsylvania and the University of Michigan Law School, both magna cum laude. After law school, he clerked for Chief Judge Edward R. Becker of the U.S. Court of Appeals for the Third Circuit. 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 baseball, skiing, drinking coffee, and travel.

Diller teaches State and Local Government, Property, and Public Health Law, and has also taught First Amendment and State Constitutional Law.  In Fall 2020, he will be teaching a new, self-designed course on Legal Implications of the Covid-19 Pandemic.  Diller has directed Willamette Law's Certificate Program in Law and Government since 2014.
