I. INTRODUCTION
A flowchart belongs in a commercial outline. Why would any selfrespecting legal scholar write a symposium piece presenting one? Well,
the Erie doctrine is different. First, it is very, very complicated. I have
never seen an Erie flowchart in a commercial outline that did not have
substantial errors or omissions. Academic treatment, for its part, tends to
work in the weeds, without presenting the Erie doctrine in an organized
and comprehensive way. What I offer below is, I think, the first correct
and complete flowchart for Erie cases.
Second, a properly formulated and sufficiently detailed flowchart,
with accompanying explanations, can go a long way toward quieting
academic worries that the Erie doctrine is fundamentally flawed. I hope
to show that Erie problems are standard choice-of-law problems, and the
way that the Supreme Court has told federal courts to deal with them is in
keeping with that fact. Even the disagreements one sees on the Court are

just what one would expect given the nature of the choice-of-law
problems at issue. The Supreme Court’s Erie jurisprudence isn’t perfect,
but it largely makes sense.
The third reason an Erie flowchart is worthy of academic treatment
is that it helps highlight unexplored problems. Despite countless articles
on Erie, there is a surprisingly large number of issues that have not been
discussed in much detail. Identifying them is part of what I will try to do
here.
I begin by describing what I believe are the four considerations that
come into play in an Erie problem. I then present the flowchart, followed
by a lengthy explanation of each step.
II. THE FOUR CONSIDERATIONS IN AN ERIE PROBLEM
First, some fundamentals. An Erie problem arises when a federal
court facing an issue must choose between using a standard drawn from
another sovereign’s law or using an independent federal standard. I
believe there are four considerations that can come into play in the federal
court’s choice.
A.
Sovereignty Considerations
The first two considerations consist of reasons the federal court
might have to use another sovereign’s standard. The first and most
obvious of these is respect for the other sovereign’s lawmaking authority.
Let us call these sovereignty considerations.
Although the relevant sovereign is usually a state, it might be a
foreign nation. Indeed, the place of foreign law in Erie problems is a big
gap in the literature, which almost always speaks of Erie problems as if
they exclusively involve the choice between federal and state legal
standards. 1
An example of sovereignty considerations in action is Erie Railroad
v. Tompkins itself. In Erie, the Supreme Court held, in part, that a federal
district court in New York had to use Pennsylvania’s standard on the duty
of care that a New York railroad has to a Pennsylvania trespasser in
Pennsylvania, out of respect for Pennsylvania’s lawmaking authority. 2
Notice that if sovereignty considerations come into play, the other

REV. 1531 (2011). For a response, see Michael Steven Green, Erie’s International Effect, 107 NW. U.
L. REV. 1485 (2013). Also unexplored is the role of the law of federal territories such as the District
of Columbia or Guam, which derive their lawmaking power from the federal government.

sovereign must want the federal court to use its standard to decide the
issue (in the sense that the appropriate authorities of the other sovereign
would, if asked, say they want that result). Thus, to understand Erie as
being about respect for Pennsylvania’s sovereignty, we must assume that
the Pennsylvania Supreme Court would have said it wanted a federal court
facing the facts in Erie to use Pennsylvania’s standard. If it wouldn’t have
said that—if the standard was intended to bind only Pennsylvania state
courts—there would have been no assertion of Pennsylvania regulatory
authority the federal court in Erie could have failed to respect.
Although the terms “substantive” and “procedural” have many
different meanings, 3 a law can be called substantive if the sovereign that
created it intends it to be used in other court systems and procedural if the
sovereign intends it to be used only in its own courts. Unless otherwise
noted, that is how I will use the terms here. Thus, one can say that
sovereignty considerations are not implicated unless the other sovereign’s
law is substantive in the relevant sense.
One reason Erie problems are challenging is that it is so difficult to
determine whether another sovereign’s law is substantive or procedural.
Unless the question is certified to the Pennsylvania Supreme Court, no
