The Full Analysis

The Full Analysis

Hanna v. Plumer organizes the preceding cases by splitting the Erie problem into two tracks, according to whether federal law speaks to the disputed point. When a valid Federal Rule of Civil Procedure is on point, the Rule governs a diversity case even over a conflicting state rule, so long as it is arguably procedural and valid under the Rules Enabling Act. When no federal directive is on point, Hanna asks instead whether ignoring the state rule would encourage forum shopping, which carries York’s outcome-determination idea forward in a form tied to the purposes of Erie. Byrd v. Blue Ridge Rural Electric Cooperative, Inc. adds a third consideration: a weighing of the federal system’s own interests against a state rule that would otherwise apply.¹ Each decision answers a different question, so a new fact pattern calls on them in a fixed order.

The order matters because a valid federal provision on point displaces a conflicting state rule on its own authority. A court that began with the twin aims could yield to state law in a case the Rule had already settled. Ragan and similar decisions looked like that mistake, and Hanna explained them as cases in which the Federal Rule was narrower than the losing party urged, so that no Rule covered the point and Erie properly sent the court to state law.³ The federal-interest check comes last because it works as a safety valve on a state rule that would otherwise apply.⁴ Compressed into one question, the whole structure asks whether a dominant federal interest justifies displacing state law, and the clearest such interest is a federal provision that actually covers the disputed issue.⁵

Step One: Federal Law on Point

Every diversity problem begins with a threshold question: does federal law already answer the disputed issue? The weighing taught in the earlier sections is needed only when it does not. Hanna v. Plumer states the rule for the most common federal source. When a valid Federal Rule of Civil Procedure is on point, the Rule applies in a diversity case even if it conflicts with a state rule, so long as it is arguably procedural and valid under the Rules Enabling Act. The plaintiff in Hanna served an executor by leaving the papers with his wife at their residence, a method Rule 4(d)(1) (now Rule 4(e)(2)) allowed, although a Massachusetts statute required delivery in hand.⁶ The lower courts dismissed the suit too late for the plaintiff to start over, and the Supreme Court reversed because the Rule governed the manner of service and was valid.⁷ That settled the case without any weighing of outcomes under Erie.

A Rule outranks a conflicting state rule because of what a Rule is. The Rules Enabling Act authorizes the Supreme Court to prescribe rules for the practice and procedure of the district courts, and it adds that such rules “shall not abridge, enlarge or modify any substantive right.”⁸ Congress could delegate that power because the Constitution’s provision for a federal court system, augmented by the Necessary and Proper Clause, carries with it power to make rules governing practice and pleading in those courts, including matters in the uncertain area between substance and procedure that are rationally capable of classification as either.⁹ A valid Rule is therefore federal law, and the Supremacy Clause makes federal law control over a conflicting state rule.¹⁰ Erie itself raises no obstacle. It concerned the railroad’s duty to Tompkins, a question substantive in every traditional sense on which no federal lawmaking power existed, and it neither said nor implied that measures like Rule 4(d)(1) are unconstitutional.¹¹

The same opinion explains why the outcome reasoning of York and Ragan has no role once a Rule is on point. The Erie rule and York’s guidelines were built to control a different kind of decision, because a case covered by a Rule is “a far cry from the typical, relatively unguided Erie choice.” In such a case “the court has been instructed to apply the Federal Rule, and can refuse to do so only if the Advisory Committee, this Court, and Congress erred in their prima facie judgment that the Rule in question transgresses neither the terms of the Enabling Act nor constitutional restrictions.”¹² Three bodies have therefore already examined the Rule: an advisory committee drafted it, the Supreme Court promulgated it, and Congress had the chance to block it. A court that declines to apply the Rule is saying all three erred, which is why the court’s own view of how much the Rule affects outcomes does not matter.

The argument that Erie, as refined in York, demands state law whenever federal law would change the result fails at this step for a reason Hanna gave directly: the Erie rule has never been invoked to void a Federal Rule.¹³ Holding that a Rule must cease to function whenever it alters the mode of enforcing state-created rights would, in the Court’s words, “disembowel either the Constitution’s grant of power over federal procedure or Congress’ attempt to exercise that power in the Enabling Act.”¹⁴ The practical reason is that the Rules apply in every federal civil case. If each state rule that might change a result could displace them, no litigant could rely on a Rule even for something as mechanical as serving a summons, which is the risk the plaintiff in Hanna ran.¹⁵

A Federal Rule is only one of the federal sources that can end the inquiry here. A constitutional provision that dictates federal practice controls in the same way, and the Seventh Amendment’s jury-trial guarantee is an example, since the right to jury trial in federal court is a matter of federal law in diversity and other actions alike.¹⁶ A federal statute governing federal practice controls under the Supremacy Clause unless Congress lacked power to enact it, and because Congress may regulate matters that fall in the uncertain area between substance and procedure, a statute with a procedural purpose will ordinarily prevail over contrary state procedure.¹⁷ Stewart Organization, Inc. v. Ricoh Corp. shows the point. Alabama law treated forum-selection clauses as unenforceable, but the Court held that 28 U.S.C. § 1404(a) governs whether a federal court transfers a case, so the clause became one factor in the statutory transfer decision and state law yielded. A judge-made routine that no constitutional provision, statute, or Rule requires is a different matter. It is not federal law of this kind, and a conflict with it is the unguided choice that the later steps address.¹⁸

On an exam, the scope question does most of the work, because whether a Rule reaches the point is a matter of interpretation, and the answer decides whether Erie is ever reached. Hanna itself observed that in the cases where state law had prevailed over an argument based on a Rule, the scope of the Rule was narrower than the losing party urged, so no Rule covered the point and Erie commanded the enforcement of state law.¹⁹ Walker v. Armco Steel Corp. shows the move at work. The plaintiff, a carpenter injured when a nail he was hammering shattered, filed a products-liability suit in federal court in Oklahoma within the limitations period but served the defendant only after it ran. Oklahoma law made service the event that stops the clock, while Rule 3 says an action is commenced by filing a complaint.²⁰ Ragan v. Merchants Transfer & Warehouse Co. had earlier required dismissal on nearly identical facts despite Rule 3.²¹ Walker avoided the collision by holding that “in diversity actions Rule 3 governs the date from which various timing requirements of the federal rules begin to run, but does not affect state statutes of limitations.” With no Rule on point, the court went on to the unguided choice and applied state law. The same absence of a collision explains Rule 54(c), which says a final judgment should grant the relief to which a party is entitled even if the pleading did not demand it. In a diversity case the entitlement comes from state law, so where state law bars punitive damages the Rule gives the plaintiff no way to recover them.²²

Courts do not always read a Rule as narrowly as Walker read Rule 3, which is what makes the scope question hard. Walker itself said that the Federal Rules should be given their plain meaning and need not be read narrowly just to avoid a direct collision, yet the Court has also seemed to favor readings that avoid conflict with state law.²³ In Burlington Northern Railroad Co. v. Woods, Alabama imposed a mandatory ten percent penalty on any appellant who lost an appeal of a money judgment, while Appellate Rule 38 let the federal court decide whether to penalize a frivolous appeal and in what amount. The Court found a direct collision, because the fixed state penalty would have deprived the federal court of discretion to impose a penalty of less than ten percent, and the Rule controlled.²⁴ The difference between the two cases lies in what each provision addressed. Rule 3 supplied a starting point for the federal timetable and said nothing about when a state-created claim expires, while Rule 38 addressed the very question of the penalty that the state statute fixed. The Court has asked whether a Rule is broad enough to reach the point in dispute, but it has never announced a test for when a Rule collides with state law.²⁵ An answer on scope should therefore compare what the Rule says with what the state rule would do to it, and a student who assumes that every Rule touching the subject controls has skipped that comparison.

If the Rule does cover the point, the next question is validity, which has a constitutional part and a statutory part. The constitutional part is satisfied by anything arguably procedural, as Hanna’s reference to matters rationally capable of classification as either substance or procedure shows.²⁶ The statutory part asks whether the Rule falls within the Enabling Act’s grant of power over practice and procedure, and the Court took its test from Sibbach v. Wilson & Co.: “The test must be whether a rule really regulates procedure,—the judicial process for enforcing rights and duties recognized by substantive law and for justly administering remedy and redress for disregard or infraction of them.”²⁷ The Act’s proviso, that a Rule may not abridge, enlarge, or modify a substantive right, is where state substantive interests re-enter. A Rule that touches rights only incidentally satisfies it, as the Court held when it upheld a Rule allowing service anywhere within the state in Mississippi Publishing Corp. v. Murphree.²⁸ In practice the question is rarely live, because no Federal Rule has ever been found to violate the Enabling Act, so a Rule that covers the point will very likely govern.²⁹

A recent case that pressed on the limits of that deference is Shady Grove Orthopedic Associates, P.A. v. Allstate Insurance Co., a 5–4 decision holding that Rule 23 controlled over a New York statute barring class actions to recover statutory penalties. Justice Scalia’s opinion described the order of inquiry this way: “We do not wade into Erie’s murky waters unless the federal rule is inapplicable or invalid.”³⁰ Even the five Justices in the majority disagreed about how to judge a Rule’s validity. Justice Stevens, concurring, would have examined whether the state law has substantive objectives that deserve respect, although he found the New York law procedural, while the four dissenters would have read Rule 23 to avoid the collision.³¹ The decision confirms that no simple formula resolves these problems.³²

An essay on pleading shows how the order of the questions decides the answer. What should a diversity court do when state courts apply a lenient pleading standard, the plaintiff can satisfy it, and the plausibility standard that Rule 8(a)(2) has been read to impose under Twombly and Iqbal would lead to dismissal? The tempting response runs through York and the twin aims and favors the state standard, because the federal standard ends the case. The correct response never reaches those cases. Rule 8(a)(2) and the decisions interpreting it apply in diversity cases even though the choice looks outcome-determinative, because the matter is settled at the gateway and the outcome test does not yet apply.³³ Only when nothing federal covers the point does the problem become the unguided Erie choice that occupies the rest of this chapter, and the next step takes up how that choice is made.

Step Two: Outcome and Aims

Once step one shows that no constitutional provision, federal statute, or Federal Rule of Civil Procedure covers the disputed point, the court faces what is usually called an unguided Erie choice: state law on one side and, on the other, a federal practice that rests on nothing more than judicial habit. Hanna v. Plumer governs that choice. It tied the outcome-determination test of Guaranty Trust Co. v. York to the purposes behind Erie, so that the test “cannot be read without reference to the twin aims of the Erie rule: discouragement of forum-shopping and avoidance of inequitable administration of the laws.”³⁵ A diversity court follows the state rule when ignoring it would bring about one of those two evils.³⁶ Step two turns that instruction into a question that can be put to any state rule.

The question has three parts, and each does separate work. The first asks whether the choice between the state rule and the federal practice would be outcome-determinative, meaning likely to change how the case comes out. The second fixes the vantage point at the moment of choosing where to file, and the third sets the yardstick at the twin aims. Together, the vantage point and the yardstick raise the bar, because the court looks for very strong signs that the result would change if federal practice replaced state law. If the choice falls short of that mark, the federal practice applies and the analysis ends. If it clears the mark, the state rule presumptively applies and the problem moves to the federal-interest check in step three.³⁷

The bar sits high because each aim is triggered only by a difference of some size. Forum shopping is a decision made before suit: a lawyer compares two courthouses and picks the one whose rules favor the client. A difference can distort that decision only if it is visible at that moment and large enough to matter to a rational litigant, so the working question asks whether applying the state rule would affect the litigants’ fortunes so much that ignoring it would likely lead a plaintiff to choose the federal court.³⁸ Inequitable administration looks at the two litigants once the case is filed. Two people holding the same state-created claim should not receive materially different treatment merely because one of them is a citizen of another state and could reach the federal courthouse. Not every difference between state and federal practice raises either concern, and a trivial variation satisfies neither aim.³⁹ A rule that clears the bar is one a litigant would notice before filing, which is why a state limitations period or choice-of-law rule, where the plaintiff often has a clear incentive from the start to prefer one version, so readily wins at this step.⁴⁰

The vantage point matters because a backward-looking measure proves too much. Hanna conceded that, once the case reached the court, following the Massachusetts in-hand service requirement would have ended the suit, and it answered that in that sense “every procedural variation is ‘outcome-determinative.’”⁴¹ The Court looked instead to the plaintiff’s position when choosing a forum. The two rules differed only in the manner of service, and it is very doubtful that a plaintiff would pick federal court merely to avoid serving the defendant in person, since the effort needed to do so is only marginally greater than the effort the Federal Rule requires.⁴² A defendant who says only that the state rule would end the case has described what nearly any rule produces once a party has disobeyed it. That defendant has not shown that anyone would have picked a courthouse because of the rule.

The strong end of the range is easy to recognize because the rule’s effect is visible before anyone files. A state cap of $250,000 on punitive damages illustrates it, where no federal rule, statute, or constitutional provision addresses the subject. Judged from the time of filing, the cap would necessarily limit what the plaintiff can recover, so a plaintiff hoping for a larger award would always prefer the federal court if that court ignored the cap. The choice is therefore outcome-determinative, and the court carries the problem to step three, where no federal interest comparable to the one in Byrd stands against the cap.⁴³ The same reasoning explains why a state limitations period controls in a federal diversity court.⁴⁴ It also explains why the burden of proof does. Burden of proof can decide a case, especially when all first-hand witnesses are dead, because the party who carries it usually loses when proof is out of reach for both sides. The burden of pleading, which requires only a verbalization on a piece of paper, carries no comparable force.⁴⁵

The weak end is just as recognizable. The allocation of issues between judge and jury is the standard example of a state rule that does not clear the bar, because moving from the state allocation to the federal one is not heavily outcome-determinative and will not induce a plaintiff to shop for a forum.⁴⁶ The reason is predictability. A lawyer can read a cap or a limitations bar and know before filing that it limits or ends the claim, but nobody can know in advance that a judge would resolve a disputed fact differently from a jury, since that turns on the witnesses and the evidence.

A state rule can prevail at this stage by either of two routes. The first is that the rule defines the right itself. A state rule bound up with the definition of the parties’ rights and obligations must be given effect, and balancing cannot be used to alter the content of a state-created right.⁴⁷ A federal court hearing a state-created claim has no power to write different content for the claim. A rule that fixes what the plaintiff may recover or when the claim expires is therefore substantive in the Erie sense, and both the outcome inquiry and the federal-interest check fall away. Gasperini v. Center for Humanities shows how little a label matters on this route. New York’s “deviates materially” standard for excessive verdicts was framed as a procedural instruction, yet the Court treated it like a damages cap, because the state’s objective was manifestly substantive.⁴⁸

The second route is open even when the rule has no claim to define the right. A state rule that regulates only the form or mode of enforcing a right can still be outcome-determinative in the strong sense described above, and in that event the state rule presumptively applies, although an important federal interest can still outweigh it at step three.⁴⁹ The two routes differ in finality. A rights-defining rule settles the matter at once, while a form-or-mode rule with strong outcome effects earns only a presumption that the next step can rebut.

On an essay in this unsettled area, the weights can be stated openly. The more heavily outcome-determinative the choice and the more likely it is to induce forum shopping, the more the balance leans toward the state rule, and a federal policy governing federal trial procedure pulls the other way.⁵⁰ Some treatments compress the same ideas into four factors: how tightly the state rule is bound up with the right, how likely a different law is to produce forum shopping or unequal administration, how strong the federal interest is, and whether a federal standard would intrude on a legitimate state regulatory concern.⁵¹ The frequent mistake at this step is to label the state rule procedural and stop, or to ask whether it could change the result after a party has already stumbled. The first skips the aims, and the second measures from the wrong moment, so each reaches the wrong default.

Step Three: Federal Interest Check

The last question in the sequence comes from Byrd v. Blue Ridge Rural Electric Cooperative, Inc. When no federal rule or statute is on point and the substantive or procedural character of the issue is unclear, Byrd directs a federal court to weigh the interests of the state and of the federal judicial system in having their own rules applied.⁵³ Step three is that weighing in its narrow modern role, and it opens only when step two has pointed toward state law. That happens when the choice between the state rule and federal practice is outcome-determinative from the standpoint of someone deciding where to sue, and the state rule only regulates the form and mode of enforcing a right without defining the parties’ rights.⁵⁴ In Byrd itself, the South Carolina rule that let the judge decide employee status was not bound up with the definition of the parties’ rights and obligations but was merely a form and mode of enforcing the compensation scheme, so the federal court was not constitutionally compelled to apply it.⁵⁵ A rule in that posture applies presumptively, so the remaining question is whether an important federal interest outweighs the presumption.⁵⁶ If step two ended with federal practice, or if the state rule is bound up with the parties’ rights and obligations, no weighing occurs at all.

The valve exists because step two, left alone, would reach too far. The outcome-determinative test treats many issues as substantive, and Byrd counteracts that stance for state forms and modes of enforcement by allowing important federal interests to prevail over state law.⁵⁷ The mechanism lies in what each side of the scale protects. A state defines the rights it creates, and a federal court hearing a state-created claim has no power to write different content for them. A rule about how the federal court conducts its own proceedings defines no one’s right, and the federal system is, in the Court’s words, “an independent system for administering justice to litigants who properly invoke its jurisdiction.”⁵⁸ The policy of uniform enforcement of state-created rights therefore cannot in every case require compliance with a state rule, not bound up with rights and obligations, that disrupts the federal system’s allocation of functions between judge and jury.⁵⁹ Without the valve, any state rule with some effect on results could reshape how federal courts operate.

What counts as a weighty federal interest is a question about the federal system’s own structure. The inquiry reduces to whether some dominant federal interest justifies displacing the state rule that would otherwise govern, and Byrd is the example in which the federal courts’ interest in allocating adjudicative functions between court and jury was strong enough to do so.⁶⁰ South Carolina sent a disputed immunity question to the judge and federal practice sent it to the jury. The Court found “a strong federal policy against allowing state rules to disrupt the judge-jury relationship in the federal courts,” even though the choice might affect the outcome.⁶¹ The same structural interest explains the split result in Gasperini v. Center for Humanities, Inc., where the Seventh Amendment’s control over review of verdicts kept federal appellate courts to abuse-of-discretion review while the district court applied New York’s standard for excessive awards.⁶² The pair of cases shows where the Amendment’s influence ends: it shapes the allocation of authority within the federal court system and leaves the content of substantive rules alone.⁶³

The scale has two pans, and a thin state interest lightens the load on the federal side. In Szantay v. Beech Aircraft Corp., a Fourth Circuit decision, a state door-closing statute gave way because applying it would have served no important state policy while frustrating the federal interest in efficient joinder of multi-party actions and in providing a convenient forum. Byrd and Szantay differ in the kind of federal interest they invoke. Byrd rested on the way the federal court divides trial work, which is part of what makes the system independent, while Szantay rested on procedural convenience and prevailed only because nothing weighty stood on the state side. At the far end of the range, a federal interest can be strong enough that the federal courts make their own law outright. Neither the Constitution nor any statute supplies the answer to controversies between states over interstate streams, and the Court has developed its own body of law for them because looking to the law of either state is plainly unsuitable when two states are in dispute.⁶⁴ An essay should therefore name the state interest and the federal interest concretely and say why one outweighs the other, because the doctrine supplies no scale and the weights are whatever the judges say they are.⁶⁵

The exception is narrow, and three limits keep it that way:

• A state rule bound up with the definition of the parties’ rights and obligations applies without any weighing, because the balance cannot be used to alter the content of a state-created right.⁶⁶
• A federal preference that does not reach the core of how the federal court operates weighs little against a state rule that affects outcomes, whereas the interest in Byrd concerned the federal system’s own division of work between judge and jury.
• The weighing decides only which law applies where either could permissibly apply, so it cannot overcome the constitutional threshold that federal authority must exist for federal rulemaking on the subject.⁶⁷

The practical result is that Byrd balancing is confined to limited circumstances, and the only clearly identifiable one is the allocation of responsibility between judge and jury, where federal policy is strong enough that state law gives way even if displacing it might encourage forum shopping within the state.⁶⁸ The Court has also shown considerable restraint in expanding the reach of federal law through this route.⁶⁹

An essay might ask whether the federal tradition of leaving damages to the jury lets a diversity court exceed a state damages cap. The question tests whether you know when this step opens at all.

The judge-jury allocation in Byrd and the cap in the hypothetical sit at opposite ends of this step. In the first, the state rule changes who performs a function the federal system treats as essential to its own operation. In the second, the state rule changes only how much the law allows the plaintiff to recover, and no federal structural interest answers it.
