This seminar is a required course for the David J. Epstein Program in Public Interest Law and Policy and enrollment is limited to Epstein Program students except by approval of the instructor. Building on the First Year Epstein Program Workshop and the summer internship experience, the seminar focuses on public interest lawyering through a close analysis of case studies and the discussion of recurring issues in public interest practice. Our method is to examine the case studies from a number of different perspectives, highlighting the many different ways of approaching problems of the sort public interest lawyers and policy analyst confront. The seminar covers questions of how public interest problems come to be framed, how clients, lawyers and their allies think about problem-solving strategies, and the multitude of roles occupied at one time or another by public interest lawyers.
