Following up on this post, and once again taking account of faculty changes since the fall 2014 PGR, here's an attempted update of the top (3.5 or higher) programs for Philosophy of Law for 2016-17, again by rough "clusters" of peer programs:

Group 1 (1)

Oxford University

Group 2 (2-5)

New York University

University of California, Los Angeles

University of Chicago

Yale University

Group 3 (6-17)

Cambridge University

Columbia University (incl. Barnard)

Cornell University

Georgetown University

King's College, London

Rutgers University, New Brunswick

University of Illinois, Urbana-Champaign

University of Michigan, Ann Arbor

University of Minnesota, Minneapolis-St. Paul

University of North Carolina, Chapel Hill

University of Pennsylvania

University of Toronto

(Note that Penn and Toronto were rather close to Group 2; in my own judgment, I would certainly put Penn in Group 2.)
