Law school leaders and professors are pushing back at U.S. Supreme Court Justice Antonin Scalia’s latest criticisms of legal education.

Scalia opposed shrinking law school to two years and ridiculed the curricula of top institutions in his May 11 commencement address at College of William and Mary Marshall-Wythe School of Law. The idea of shortening law school education, Scalia said, “rests on the premise that law school is—or ought to be—a trade school. It is not that. It is a school preparing men and women not for a trade but for a profession—the profession of law.”
