In the famous words of Justice Felix Frankfurter, Erie Railroad Co. v. Tompkins “did not merely overrule [the] venerable case” of Swift v.

Join CIT for a discussion highlighting how Erie affected the American understanding of the nature of law, the doctrinal implications of that change, and the merits of reconsidering Erie.
