John Marshall Harlan II

“ In turning from the 'outcome' test of York back to the unadorned forum-shopping rationale of Erie, however, the Court falls prey to like oversimplification, for a simple forum-shopping rule also proves too much; litigants often choose a federal forum merely to obtain what they consider the advantages of the Federal Rules of Civil Procedure or to try their cases before a supposedly more favorable judge. ”

“ But even had the Federal Rules purported to do so, and in so doing provided a substantially less effective deterrent to strike suits, I think the state rule should still have prevailed. That is where I believe the Court's view differs from mine; for the Court attributes such overriding force to the Federal Rules that it is hard to think of a case where a conflicting state rule would be allowed to operate, even though the state rule reflected policy considerations which, under Erie, would lie within the realm of state legislative authority. ”

“ Erie recognized that there should not be two conflicting systems of law controlling the primary activity of citizens, for such alternative governing authority must necessarily give rise to a debilitating uncertainty in the planning of everyday affairs. ”
