SMJ of Federal Courts

Des Moines Navigation & Railroad Co. v. Iowa Homestead Co.; Mass v. Perry; A.F.A Tours, Inc. v. Whitchurch; Louisville & Nashville R. Co. v. Mottley; Grable & Sons Metal Products, Inc. v. Darue Engineering & Manufacturing; T.B Harms Co. v. Eliscu; Gunn v. Minton, United Mine Workers of America v. Gibbs; & Exxon Mobile Corp. v. Allapattah Services, Inc.

Des Moines Navigation: What happened?

Iowa Homestead Co. (IHC) sued Des Moines Navigation & Railroad Co. over taxes connected to disputed Iowa land. But this was not the parties’ first lawsuit. An earlier lawsuit involving the same general property disputes had been removed from Iowa state court to federal Circuit Court, where a decree was ultimately entered.

In the later lawsuit, Des Moines Navigation argued that the earlier federal decree barred IHC from relitigating matters already decided. IHC responded that the earlier decree should not count because, according to IHC, the federal court lacked subject-matter jurisdiction to enter it in the first place.

Des Moines Navigation: Why was federal diversity jurisdiction problematic?

IHC and Des Moines Navigation were both Iowa corporations/citizens. Therefore, there was no diversity between those two parties.

However, the earlier lawsuit contained additional defendants who were New York citizens. That complicated the jurisdictional analysis because there were separate Iowa-versus-New-York controversies within the larger lawsuit.

Des Moines Navigation: What were the separate controversies involving the New York defendants?

The New York defendants claimed individual tracts of the disputed land. They were not all claiming the property jointly.

Thus, the lawsuit contained separate disputes between:

IHC (Iowa) → individual New York defendants

Those controversies involved citizens of different states even though the separate dispute between IHC (Iowa) and Des Moines Navigation (Iowa) did not.

Des Moines Navigation: Who removed the earlier lawsuit to federal court, and why?

Three New York defendants filed the required affidavits and petitions seeking removal from Iowa state court to federal Circuit Court.

Their individual controversies with the Iowa plaintiff were between citizens of different states. After they sought removal, however, the entire lawsuit - including the controversy between the two Iowa citizens - was transferred to federal court.

Des Moines Navigation: What historical removal rule allowed the New York defendants to seek removal?

The case involved the Act of 1867, not today's removal statute.

Under that law, when a state-court suit contained a controversy between a citizen of the state where the suit was brought and a citizen of another state, an out-of-state citizen who believed prejudice or local influence would prevent justice in state court could file the required affidavit and petition seeking removal to federal Circuit Court.

This historical rule is important because modern removal law should not simply be projected backward onto the case.

Des Moines Navigation: If some controversies were diverse, what was potentially WRONG with the removal?

The questionable part was that the entire lawsuit was transferred to federal court.

The New York defendants had separate diverse controversies with IHC. But IHC and Des Moines Navigation were both Iowa citizens.

Thus, the federal Circuit Court potentially should have either remanded the case or limited itself to the removable controversies involving the diverse New York defendants, rather than adjudicating the Iowa-versus-Iowa controversy as well.

Des Moines Navigation: Did the Supreme Court hold that the entire lawsuit actually satisfied diversity jurisdiction?

No. That is an important potential misunderstanding.

The Court's key point was not that federal jurisdiction over the entire lawsuit was necessarily correct. The Circuit Court may have made a jurisdictional error by retaining the entire suit or adjudicating the dispute between the two Iowa citizens.

The question was what legal effect that possible jurisdictional error had on the already-entered federal judgment.

Des Moines Navigation: Did IHC object to federal jurisdiction when the earlier case was removed?

No. After removal, all defendants appeared and defended the lawsuit. IHC actively litigated against Des Moines Navigation and the other defendants in federal Circuit Court and later on appeal without objecting to federal jurisdiction.

Only later, when Des Moines Navigation tried to use the earlier decree against IHC, did IHC argue that the decree was ineffective because the federal court lacked jurisdiction.

Des Moines Navigation: Did IHC's failure to object GIVE the federal court subject-matter jurisdiction?

No. Parties cannot create federal subject-matter jurisdiction through consent, acquiescence, or failure to object.

The significance of what happened is different: the federal court actually considered and exercised its authority, the parties litigated the case, and a final judgment resulted. The later question was therefore whether an error in the court's jurisdictional determination made that judgment automatically void.

Do not confuse “the parties cannot create SMJ” with “every judgment involving an SMJ error is automatically a nullity.”

Des Moines Navigation: What was the Supreme Court really deciding?

The central question was whether the earlier federal decree was absolutely void for want of jurisdiction, meaning it could simply be disregarded, or whether it remained a valid and binding prior adjudication unless and until it was properly reversed, vacated, annulled, or otherwise set aside.

Thus, the case concerns the effect of an alleged jurisdictional error on an already-entered judgment, not merely whether the original jurisdictional ruling was correct.

Des Moines Navigation: How can a court act if whether it has jurisdiction is itself uncertain?

A court necessarily has authority to determine whether jurisdiction exists.

The federal Circuit Court therefore had authority to decide whether the lawsuit was:

• removable in its entirety,

• removable only in part, or

• not removable at all.

The court could make that jurisdictional determination correctly or incorrectly.

Des Moines Navigation: What crucial distinction explains the Court's reasoning?

Having authority to decide whether jurisdiction exists is different from necessarily having jurisdiction over the underlying merits.

A court must be able to determine whether a case belongs before it. If it incorrectly concludes that jurisdiction exists, it has committed a jurisdictional error. But the fact that its decision was erroneous does not necessarily mean that the resulting judgment legally never existed.

Des Moines Navigation: What is the difference between an erroneous judgment and a void/null judgment?

An erroneous judgment contains a legal error and may therefore be subject to reversal through proper review.

A void or null judgment, by contrast, is treated as lacking legal force.

Des Moines Navigation teaches that a federal court's erroneous decision concerning its own jurisdiction does not automatically transform its resulting judgment into a legal nullity.

Des Moines Navigation: If IHC believed the federal court lacked jurisdiction, what was the proper way to challenge it?

IHC could have challenged the federal court's jurisdictional determination through direct review, including appellate review.

If the Circuit Court improperly retained the whole lawsuit or adjudicated a controversy it lacked jurisdiction to decide, the decree could have been reversed as erroneous.

But IHC could not necessarily wait until later litigation and simply treat the still-operative earlier decree as though it had never existed.

Des Moines Navigation: What is the difference between direct and collateral attack?

A direct attack challenges a judgment through the case itself or through the established review process - for example, appealing the court's jurisdictional ruling.

A collateral attack occurs when a party later challenges the judgment's validity in a different proceeding.

Des Moines limits the ability to collaterally treat an earlier federal judgment as a nullity merely because the federal court may have made an erroneous jurisdictional determination.

Des Moines Navigation: What did the Supreme Court hold about the earlier federal decree?

The earlier decree was not a nullity.

Even assuming the Circuit Court erred by retaining the entire lawsuit or adjudicating the controversy between two Iowa citizens, it had authority to determine the removability/jurisdictional question.

The decree therefore remained legally effective unless properly set aside and barred IHC's later attempt to relitigate matters already decided.

Doesn't Des Moines Navigation contradict Capron because Capron says SMJ cannot be waived?

No. They address different questions.

Capron: Does the federal court actually possess subject-matter jurisdiction? SMJ must exist and cannot be created through consent or waiver.

Des Moines: What happens after a federal court has determined that jurisdiction exists and entered a judgment, but that jurisdictional determination may have been erroneous?

Thus, Des Moines does not say parties can consent to SMJ. It says a jurisdictional error does not necessarily make an already-entered judgment automatically nonexistent.

If you remember ONE thing about Des Moines Navigation, what should it be?

SMJ error ≠ automatically void judgment.

A federal court has authority to determine whether it has jurisdiction. If it incorrectly decides that jurisdiction exists, that decision may be erroneous and reversible on direct review without making the resulting judgment automatically null and open to collateral attack.

That is why Des Moines can coexist with Capron: SMJ cannot be created by waiver, but an erroneous SMJ determination does not necessarily erase a final judgment from legal existence.

What happened in Mas v. Perry?

Jean Paul Mas, a French citizen, and Judy Mas, an American who had been domiciled in Mississippi, were graduate students at LSU in Louisiana. After marrying, they rented an apartment in Baton Rouge from Oliver Perry, a Louisiana citizen. They discovered that Perry had installed two-way mirrors in their bedroom and bathroom and had been watching them during the early months of their marriage. The Mases sued Perry in federal court. The central Civil Procedure question became whether the federal court had diversity subject-matter jurisdiction, particularly whether Judy was a citizen of Louisiana or Mississippi.

What happened procedurally in Mas v. Perry?

The case went to a jury in federal district court. At the close of the plaintiffs’ case, Perry moved to dismiss for lack of subject-matter jurisdiction. The district court denied the motion, and the jury awarded $5,000 to Jean Paul Mas and $15,000 to Judy Mas. Perry appealed solely on jurisdictional grounds. The Fifth Circuit affirmed, concluding that federal subject-matter jurisdiction existed.

What was the primary subject-matter-jurisdiction issue in Mas v. Perry?

The difficult issue was Judy Mas’s state citizenship. Perry was a Louisiana citizen. If Judy was also a Louisiana citizen, complete diversity would be destroyed. If she remained a Mississippi citizen, she was diverse from Perry.

The court therefore had to determine Judy’s domicile, because state citizenship of a natural person for § 1332 purposes depends on domicile, not merely where the person happens to live.

Mas v. Perry: What is the basic rule for determining a natural person’s state citizenship under § 1332?

For diversity jurisdiction:

State citizenship = U.S. citizenship + domicile in that state.

Merely residing in a state does not make someone a citizen of that state for diversity purposes.

Mas v. Perry: What is domicile, and what two things are required to establish a new domicile?

Domicile is a person’s true, fixed, and permanent home - the place regarded as the person’s principal home.

To acquire a new domicile, the person needs BOTH:

1. Physical presence/residence in the new state, AND

2. Intent to remain there.

Physical presence without the necessary intent does not change domicile.

Mas v. Perry: Why are “residence” and “domicile” not interchangeable for diversity jurisdiction?

Residence tells you where someone is living; domicile determines state citizenship.

Someone may live in a state for a substantial period without making it their fixed home. Thus, a person can reside in Louisiana while remaining domiciled - and therefore a citizen - somewhere else.

That distinction was crucial in Mas: Judy lived in Louisiana but was not necessarily domiciled there.

Mas v. Perry: Why did Judy Mas’s years living in Louisiana not automatically make her a Louisiana citizen?

Because she and Jean Paul were in Louisiana as students at LSU. Judy satisfied the physical-presence component, but the court found that she lacked the necessary intent to remain in Louisiana.

Therefore, she had not acquired a Louisiana domicile.

Students are a classic domicile problem. Living somewhere for school may establish physical presence without establishing intent to make that state one’s fixed home.

Mas v. Perry: Judy Mas testified that she did not intend to return to her parents’ home in Mississippi. Why didn't that destroy her Mississippi domicile?

Because losing an old domicile requires acquiring a new one. This is called the “continuing domicile” rule.

It was not enough that Judy no longer intended to return to Mississippi. She still needed to establish a new domicile somewhere else through physical presence + intent to remain.

Because she had not established Louisiana or another state as her new domicile, her existing Mississippi domicile continued.

Mas v. Perry: What is the major trap involving “intent” in a domicile analysis?

Do not confuse:

“I don't intend to return to my old domicile”

with

“I intend to remain in this new state.”

They are not equivalent.

Judy’s lack of intent to return to Mississippi did not prove an intent to remain in Louisiana. Without a new domicile, Mississippi continued as her domicile.

Mas v. Perry: Why did Judy Mas’s marriage to Jean Paul Mas create an additional domicile issue?

Historically, the law often treated a wife’s domicile as following her husband’s. Jean Paul was a French citizen, however, and the Fifth Circuit refused to mechanically apply that old rule.

The court held that an American woman’s state citizenship and domicile do not automatically change merely because she marries a foreign citizen.

Mas v. Perry: What strange results could have followed if Judy automatically acquired Jean Paul’s domicile?

If Jean Paul were treated as domiciled in France, Judy could be treated as domiciled abroad while remaining a U.S. citizen, creating problems in assigning her state citizenship for diversity purposes.

If Jean Paul were instead treated as domiciled in Louisiana, Judy would automatically become a Louisiana citizen and lose diversity against Perry, also a Louisiana citizen.

The Fifth Circuit rejected these artificial consequences of the old derivative-domicile rule.

Mas v. Perry: What did the Fifth Circuit ultimately determine Judy Mas’s citizenship to be, and why?

Mississippi. Judy had been domiciled in Mississippi before marriage. Although she physically lived in Louisiana, she was there as a student and lacked the intent necessary to establish Louisiana as her new domicile. Her marriage to Jean Paul did not automatically change her domicile.

Because her old domicile continued until a new one was acquired, Judy remained a Mississippi citizen.

Mas v. Perry: How did § 1332(a)(1) provide jurisdiction over Judy Mas’s claim against Perry?

Section 1332(a)(1) provides diversity jurisdiction for qualifying actions between citizens of different U.S. states.

Judy = Mississippi citizen
Perry = Louisiana citizen

Therefore, Judy and Perry were citizens of different states, satisfying the citizenship component of § 1332(a)(1).

Mas v. Perry: How did § 1332(a)(2) provide jurisdiction over Jean Paul Mas’s claim against Perry?

Section 1332(a)(2) provides what is commonly called alienage jurisdiction for qualifying actions between a citizen of a U.S. state and a citizen or subject of a foreign state.

Jean Paul = France
Perry = Louisiana

Therefore, Jean Paul’s claim fell under § 1332(a)(2).

Mas v. Perry: What is the complete-diversity rule discussed in Mas v. Perry?

Complete diversity generally requires that no plaintiff be a citizen of the same state as any defendant.

The opinion cites Strawbridge v. Curtiss for this traditional rule.

Mas v. Perry: At what point in time is diversity citizenship determined?

Diversity must exist when the complaint is filed.

Later changes in a party’s citizenship ordinarily do not destroy diversity jurisdiction that properly existed at the time of filing.

So when analyzing diversity, ask:

“What was each party’s citizenship when the lawsuit was filed?”

Mas v. Perry: Who bears the burden of establishing diversity jurisdiction?

The party invoking federal diversity jurisdiction bears the burden of alleging the jurisdictional basis and, when jurisdiction is properly challenged, proving the jurisdictional facts.

In Mas, once Perry challenged jurisdiction, the plaintiffs bore the burden of establishing the necessary jurisdictional facts.

Mas v. Perry: Why could Perry challenge subject-matter jurisdiction even after the case had already proceeded to trial?

Because subject-matter jurisdiction concerns the federal court’s power to hear the case; it is not something the parties can simply ignore or cure by proceeding with the litigation.

Perry raised the jurisdictional challenge at the close of the plaintiffs’ case, and the Fifth Circuit considered the jurisdictional issue on appeal after final judgment.

Mas v. Perry: Did Mas v. Perry depend on supplemental jurisdiction to keep Jean Paul and Judy Mas’s claims together?

No. Each spouse independently had a statutory basis for diversity jurisdiction.

Jean Paul → § 1332(a)(2) alienage jurisdiction.
Judy → § 1332(a)(1) state-to-state diversity.

The court noted the practical sense of hearing their closely related claims together, but jurisdiction did not depend on one spouse merely piggybacking on the other's claim.

What was A.F.A. Tours’ business, and what information did it claim was legally important?

A.F.A. Tours (“AFA”) operated a travel business specializing in luxury tours for U.S. travelers going to places such as Australia, New Zealand, and New Guinea.

AFA claimed that it had invested substantial time, money, and effort developing confidential business information, including:

• customer/client lists;

• marketing information; and

• information relating to its tours.

AFA treated this information as confidential trade secrets. This became important because AFA later accused its former tour escort, Desmond Whitchurch, of taking and using this information to compete against it.

Who was Desmond Whitchurch, and how did he obtain access to AFA’s allegedly confidential information?

Whitchurch worked for AFA from approximately 1972 through 1989 as its exclusive tour escort in the relevant South Pacific destinations.

Because he worked with AFA and its customers for about 17 years, he gained access to some of AFA’s allegedly confidential customer and business information.

AFA alleged that after leaving the company in 1989, Whitchurch:

1. improperly took confidential information AFA had provided him;

2. started his own competing tour business; and

3. contacted, or intended to contact, people from AFA’s customer list.

This conduct formed the basis of AFA’s trade-secret misappropriation claim.

What did AFA ask the federal court to award against Whitchurch?

AFA sought several forms of relief:

1. Compensatory damages — AFA could not yet determine the exact amount but alleged that its damages would exceed $50,000.

2. Punitive damages — AFA requested at least $250,000.

3. Injunctive relief — AFA wanted the court to prohibit Whitchurch from using its confidential information.

These different forms of relief became important because the case ultimately centered on whether the amount in controversy exceeded the amount then required for diversity jurisdiction.

Why was $50,000 important in A.F.A. Tours v. Whitchurch?

Beginning with the Judiciary Act of 1789, Congress imposed an amount-in-controversy requirement as a limitation on diversity jurisdiction.

At the time of the case, 28 U.S.C. § 1332 required the amount in controversy in a diversity action to exceed $50,000, exclusive of interest and costs.

So even if the parties otherwise satisfied diversity requirements, AFA also needed a sufficient amount in controversy for the federal district court to exercise statutory diversity jurisdiction.

The current threshold is more than $75,000.

A.F.A. Tours: Is the amount-in-controversy requirement imposed by Article III of the Constitution?

No.

Article III, § 2 extends the federal judicial power to controversies “between Citizens of different States.” Article III itself does not require that a certain dollar amount be involved.

The amount-in-controversy requirement comes from Congress’s statutory grant of diversity jurisdiction, not from the Constitution.

Article III = constitutional ceiling
It tells us how far federal judicial power could extend.

28 U.S.C. § 1332 = congressional/statutory grant
It tells us how much diversity jurisdiction Congress has actually authorized the lower federal courts to exercise.

A.F.A. Tours: What jurisdictional issue did the district court raise during the proceedings against Whitchurch?

Interestingly, Whitchurch’s attorney initially characterized the dispute as involving whether AFA’s information actually qualified as legally protected trade secrets.

But during oral argument, the district court raised the amount-in-controversy issue on its own.

The court questioned whether AFA’s case could really be worth more than $50,000. It ultimately concluded that AFA could not establish the jurisdictional amount and dismissed the case for lack of subject-matter jurisdiction.

That shifted the appellate dispute away from the merits of trade-secret law and toward the proper standard for evaluating the amount in controversy.

A.F.A. Tours: What test governs whether the plaintiff has alleged a sufficient amount in controversy?

The governing standard comes from St. Paul Mercury Indemnity Co. v. Red Cab Co.

If the plaintiff makes a good-faith allegation that the amount in controversy exceeds the jurisdictional threshold, that allegation generally controls.

The case should be dismissed for insufficient amount in controversy only when the court can determine to a legal certainty that the plaintiff could not possibly recover enough.

This is known as the legal-certainty test.

For AFA, therefore, the question was NOT: “Can AFA prove right now that it will actually recover more than $50,000?”

The proper question was: “Can the court say to a legal certainty that AFA could NOT recover more than $50,000?”

That is a much more plaintiff-friendly standard.

A.F.A. Tours: Why does St. Paul use such a generous “legal certainty” standard rather than requiring the court to determine the plaintiff’s actual damages before proceeding?

Because doing otherwise could require the court to conduct a mini-trial on the merits merely to determine whether it has jurisdiction to conduct the actual trial.

Consider what the district court would have needed to determine AFA’s actual losses:

• How many AFA customers would Whitchurch successfully attract?

• How many future tours would AFA lose?

• How much profit did AFA earn from each customer?

• Would former customers travel to the South Pacific again?

• How much future harm would Whitchurch’s possession of AFA’s customer information cause?

Those are complicated factual questions that could overlap substantially with the merits and damages stages of the actual litigation.

The legal-certainty test avoids wasting judicial resources on a preliminary damages trial simply to determine jurisdiction.

A.F.A. Tours: Why did the Second Circuit conclude that the district court acted too quickly in dismissing AFA’s case?

The district court itself first raised the amount-in-controversy issue during oral argument on Whitchurch’s summary-judgment motion and then dismissed the case at the conclusion of that same hearing.

AFA therefore had not been given a meaningful opportunity to submit evidence specifically addressing the jurisdictional amount.

Before concluding that the jurisdictional minimum cannot be satisfied, the plaintiff must have a fair opportunity to demonstrate a good-faith possibility of recovering more than the threshold.

A.F.A. Tours: Can potential future harm count toward the amount in controversy, or is the court limited to damages already suffered?

Potential future harm can matter, particularly when the plaintiff seeks injunctive relief.

AFA was not merely asking for compensation for customers Whitchurch had already taken. It wanted an injunction preventing him from continuing to use or disclose its confidential information.

Therefore, the court could consider the value of protecting AFA from future misuse and future economic harm, rather than looking exclusively at damages already incurred when the complaint was filed.

This was particularly important because Whitchurch's competing business was still developing.

A.F.A. Tours: How can an injunction be counted toward the amount in controversy when an injunction does not itself state a dollar amount?

The court must assign a monetary value to the object of the injunctive relief. There are two approaches for determining this value:

• 1st approach considers the value of the injunction to the plaintiff

• 2nd approach considers the cost/burden of compliance to the defendant.

Court may choose either one, but the plaintiff-viewpoint is the majority. These approaches matter because the same injunction may have very different monetary values depending on whose perspective is used.

A.F.A. Tours: What did the Second Circuit ultimately hold in A.F.A. Tours v. Whitchurch?

The Second Circuit concluded that the existing record did not permit the district court to determine to a legal certainty that AFA's claims were worth $50,000 or less. Additionally, AFA had not received an adequate opportunity to present evidence specifically addressing the amount-in-controversy question.

Therefore, dismissing the action for lack of subject-matter jurisdiction was improper.

How does Mas v. Perry help explain the amount-in-controversy rule applied in A.F.A. Tours?

Mas v. Perry illustrates the distinction between:

1. the amount in controversy when the lawsuit is filed, and

2. the amount the plaintiff ultimately recovers.

In Mas, Mr. Mas ultimately received $5,000, even though the jurisdictional minimum at the time was more than $10,000.

That did not retroactively destroy diversity jurisdiction.

When the lawsuit was filed, the court could not say to a legal certainty that Mr. Mas would recover less than $10,000.

Thus, a later verdict below the threshold does not prove that the amount-in-controversy requirement was unsatisfied when the case began.

Why doesn't a federal court lose subject-matter jurisdiction when the jury ultimately awards less than the jurisdictional minimum?

Because jurisdiction was properly determined at filing, based on what was genuinely in controversy at that time.

There is also an important efficiency rationale behind the rule.

Imagine the federal court:

1. accepts the case;

2. oversees discovery;

3. resolves motions;

4. conducts a full trial; and then

5. the jury awards slightly less than the jurisdictional threshold.

If that verdict automatically destroyed subject-matter jurisdiction, all of the federal proceedings could become a tremendous waste of judicial resources.

If a plaintiff ultimately recovers less than the jurisdictional minimum, does the federal court have any mechanism for dealing with an improperly inflated claim?

Yes. 28 U.S.C. § 1332(b) gives the district court discretion concerning costs when a plaintiff who filed the case in federal court ultimately recovers less than the jurisdictional amount.

The court does not have to ignore a plaintiff who appears to have artificially exaggerated the amount in controversy merely to obtain access to federal court. The costs mechanism can discourage plaintiffs from playing “fast and loose” with the jurisdictional threshold.

How does good faith distinguish Mr. Mas from someone manipulating the amount-in-controversy requirement?

Mr. Mas's eventual $5,000 recovery did not establish that his original claim above $10,000 was dishonest.

At the time he filed, he could not know precisely what amount a jury would award, and there was no legal certainty that his recovery had to remain below $10,000.

Contrast that with someone who knowingly has a very small claim but artificially inflates it simply to obtain diversity jurisdiction - for example, representing a claim as worth $70,000 when its genuine potential value is only around $3,000.

The distinction is good faith at filing.

A disappointing verdict is not itself jurisdictional manipulation.

What does “aggregation” mean in the amount-in-controversy context?

Aggregation means adding the monetary value of multiple claims or interests together to determine whether the jurisdictional amount has been satisfied.

Whether aggregation is permitted depends heavily on who owns the claims and what type of interests are being asserted.

The rules differ between:

• one plaintiff asserting multiple claims against one defendant; and

• multiple plaintiffs attempting to combine their individual claims.

Can one plaintiff aggregate multiple claims against one defendant to satisfy the amount-in-controversy requirement of 28 U.S.C. § 1332?

Generally, yes.

One plaintiff may ordinarily add together the value of all claims against one defendant to reach the jurisdictional threshold.

Importantly, those claims do not have to be related.

Example:

A sues B for:

• $40,000 for breach of contract; and

• $40,000 for an entirely unrelated tort.

A may generally aggregate the two claims:

$40,000 + $40,000 = $80,000.

The fact that the claims arose from completely different events does not prevent aggregation when the same plaintiff owns both claims against the same defendant.

Can multiple plaintiffs ordinarily add their separate claims together to satisfy the amount-in-controversy requirement of 28 U.S.C. § 1332?

No.

Multiple plaintiffs ordinarily cannot take their separate and distinct claims and add them together merely because the combined total exceeds the jurisdictional threshold.

When may multiple plaintiffs aggregate their interests to meet the amount-in-controversy requirement of 28 U.S.C. § 1332?

Multiple plaintiffs may aggregate when they are enforcing a common and undivided interest, sometimes described as a legally indivisible interest.

“legally indivisible” does NOT mean “closely related”

Factual relatedness and legal ownership are different questions.

Why can't multiple people injured in the same accident ordinarily aggregate their damages?

Suppose three passengers are injured in the exact same car accident:

• A suffers $30,000 in damages.

• B suffers $30,000.

• C suffers $60,000.

Their claims are obviously closely related. They arise from the same accident and may involve the same defendant and evidence.

But each passenger owns an individual personal-injury claim.

If A loses, B does not suddenly become entitled to more money. B's injury remains B's injury.

Therefore, the claims are separate and distinct, not legally indivisible, and the plaintiffs cannot simply aggregate them to satisfy the jurisdictional threshold.

What practical test can help determine whether multiple plaintiffs have a common and undivided interest?

If one plaintiff fails to recover his or her share, would the other plaintiffs' shares become larger?

If yes, that suggests the plaintiffs may be asserting a common and undivided interest.

If no, meaning each plaintiff has a fixed, independent claim regardless of what happens to the other, that suggests the claims are separate and distinct.

What is the central amount-in-controversy lesson to remember from A.F.A. Tours v. Whitchurch?

Under the St. Paul legal-certainty test: A plaintiff's good-faith allegation controls unless it is legally certain that the plaintiff cannot recover above the jurisdictional threshold.

A.F.A. Tours demonstrates how broadly that potential value may need to be considered. The court may need to consider:

• compensatory damages;

• reasonably possible future losses;

• the monetary value of injunctive relief; and

• legally available punitive damages.

The court should not conduct a premature mini-trial merely to predict the eventual verdict but they should provide the plaintiff an opportunity to present evidence supporting their allegation.

Louisville v. Mottley: What happened between the Mottleys and Louisville & Nashville Railroad Co. before the lawsuit arose?

In 1871, the Mottleys were injured while passengers on LNRC because of the railroad’s alleged negligence. Rather than pursue their negligence claims for damages, the Mottleys released those claims in exchange for LNRC’s contractual promise to provide them with free railroad transportation for life.

LNRC honored the agreement for decades. But after Congress enacted a federal statute in 1906 prohibiting certain free railroad passes and transportation, LNRC stopped renewing the Mottleys’ passes as of January 1, 1907. The Mottleys then sued to force LNRC to continue honoring the lifetime-pass agreement.

Louisville v. Mottley: Why did the Mottleys believe their lifetime passes were different from ordinary “free passes”?

The Mottleys had already “paid” for their passes

Their payment was not money; it was consideration in the form of forbearance. They possessed negligence claims against LNRC and gave up their right to pursue those legally valid claims in exchange for lifetime transportation.

Louisville v. Mottley: What was the Mottleys’ actual cause of action against LNRC?

A state-law breach-of-contract claim.

Stripped to its essentials, their claim was:

LNRC promised us lifetime transportation → we provided consideration → LNRC stopped providing the promised transportation → LNRC breached the contract.

Their underlying right to relief came from state contract law.

Louisville v. Mottley: Why did LNRC believe it had a basis for demurring to the Mottleys’ complaint?

LNRC's position was essentially that even if everything alleged by the Mottleys were true, the railroad could no longer legally perform the contract because the 1906 federal statute prohibited free railroad transportation.

So LNRC was not merely saying, “We didn't make this contract.” It was arguing that subsequent federal law prevented it from continuing to perform the agreement.

The trial court rejected LNRC's demurrer and granted relief to the Mottleys. LNRC appealed to the Supreme Court.

Louisville v. Mottley: How did the Mottleys anticipate and respond to LNRC’s federal-law defense in their complaint?

First: The 1906 federal statute should not be interpreted to prohibit their particular passes, because their passes were given in exchange for surrendering valid negligence claims rather than as gratuitous free transportation.

Second: If the statute did prohibit their passes, then applying it to their existing contractual rights would violate the Fifth Amendment by depriving them of property without due process.

Thus, federal law appeared prominently in their complaint - but only because they were anticipating LNRC's defense and attempting to defeat it in advance.

Louisville v. Mottley: Why could the Supreme Court raise subject-matter jurisdiction even though neither party challenged it?

The Mottley Court specifically noted that neither party questioned jurisdiction, but federal jurisdiction is defined and limited by law. The parties therefore cannot create federal subject-matter jurisdiction simply by agreeing that it exists or by failing to object. That is why the Supreme Court could - and had to - address jurisdiction before reaching the merits.

What are the two major sources to remember when asking where federal-question jurisdiction comes from?

Article III, § 2 of the Constitution provides the constitutional authorization. It extends federal judicial power to cases “arising under” the Constitution, federal laws, and treaties.

28 U.S.C. § 1331 provides the modern statutory grant of federal-question jurisdiction to federal district courts.

The useful distinction is:

Article III § 2 = constitutional ceiling/authorization.
§ 1331 = statutory grant Congress has actually provided.

What is the Osborn “ingredient” test, and why is Osborn v. Bank of the United States relevant to Mottley?

Osborn v. Bank of the United States represents a broad interpretation of Article III's constitutional “arising under” power.

Under the Osborn concept, a case can constitutionally arise under federal law when federal law forms an “ingredient” of the case. The federal issue does not necessarily have to create the plaintiff's cause of action.

This establishes an important distinction:

Article III / Osborn → broad constitutional potential for federal jurisdiction.

§ 1331 / Mottley → narrower statutory federal-question jurisdiction.

Was federal law an “ingredient” of the Mottley controversy under the broad Osborn conception?

Yes. The 1906 federal statute was plainly part of the actual legal controversy between LNRC and the Mottleys. LNRC relied on federal law as the reason it could no longer perform the contract, and the Mottleys disputed both the statute's meaning and potentially its constitutionality.

The problem under Mottley was not that federal law had nothing to do with the controversy. The problem was where the federal question appeared: it arose through an anticipated defense rather than the Mottleys' own cause of action.

What is the well-pleaded complaint rule established by Mottley?

Federal-question jurisdiction exists under the Mottley rule only when the federal question appears from the plaintiff's own properly pleaded cause of action. The court asks whether the plaintiff's own claim, properly pleaded without unnecessary anticipatory material, arises under federal law.

Why is the well-pleaded complaint rule so strict? Why not allow federal-question jurisdiction when everyone knows a federal issue will eventually become central to the case?

First, jurisdictional control: otherwise, plaintiffs with ordinary state-law claims could potentially manufacture federal jurisdiction by inserting an expected federal defense and their response to it into the complaint. That could pull large numbers of fundamentally state-law disputes into federal court.

Second, orderly and fair pleading: the defendant should be allowed to decide which defenses to raise and how to formulate them. A plaintiff might misunderstand, oversimplify, or inaccurately characterize a defense that the defendant may ultimately waive, alter, or never assert.

Louisville v. Mottley: Does FRCP 8(c)(1) itself establish that defendants always bear the burden of proving their defenses?

No. This distinction is important. FRCP 8(c)(1) requires a defendant to affirmatively state affirmative defenses such as waiver, estoppel, statute of limitations, res judicata, and others.

But Rule 8(c)(1) does not itself establish a universal burden-of-proof rule. Who bears the burden of persuasion depends on the substantive law governing the particular defense.

Louisville v. Mottley: What is the Holmes test for determining whether a suit arises under federal law?

Justice Holmes famously formulated the idea that:

“A suit arises under the law that creates the cause of action.”

The basic question is therefore: What body of law gives the plaintiff the legal claim being asserted?

Louisville v. Mottley: How do the Holmes test and Mottley’s well-pleaded complaint rule complement each other?

Both direct attention back toward the plaintiff's own cause of action, rather than federal issues that might arise elsewhere in the litigation.

Holmes: Ask what law creates the cause of action.

Mottley: Ask whether the federal question appears in the plaintiff's properly pleaded cause of action rather than through an anticipated defense.

Louisville v. Mottley: What if the Mottleys had simply removed the contract claim and alleged only that their Fifth Amendment rights were violated?

Merely relabeling the dispute would not automatically create a valid federal cause of action.

Their Fifth Amendment theory arose because they believed application of the federal statute to their contractual rights would deprive them of property without due process. But their requested relief against LNRC, a private railroad, still concerned LNRC's contractual obligation to provide transportation.

The Fifth Amendment constrains federal governmental action. It does not automatically transform a private breach-of-contract dispute into a constitutional cause of action against the railroad.

Louisville v. Mottley: What is the Declaratory Judgment Act and Skelly Oil Co. v. Phillips Petroleum Co. add to the Mottley framework?

The federal Declaratory Judgment Act, 28 U.S.C. § 2201, allows a federal court in an appropriate case to declare the parties' legal rights.

Skelly Oil prevents the Declaratory Judgment Act from becoming a workaround for the well-pleaded complaint rule.

When jurisdiction depends on a declaratory-judgment action, the court looks to the underlying coercive action - essentially, the lawsuit that ordinarily would have been brought if declaratory relief were unavailable.

If that underlying lawsuit would merely be a state-law claim in which federal law appears as a defense, the plaintiff cannot manufacture § 1331 jurisdiction by reversing the parties’ posture and requesting a declaration about federal law.

Louisville v. Mottley: How do Holmes, Mottley, and Skelly Oil fit together as a federal-question-jurisdiction sequence?

Think of them as three protections against jurisdiction being created merely through pleading strategy:

Holmes → What law actually creates the plaintiff's cause of action?

Mottley → Does the federal question appear in the plaintiff's properly pleaded cause of action, rather than an anticipated defense?

Skelly Oil → A plaintiff cannot circumvent that restriction simply by reframing the dispute as a request for a federal declaratory judgment.

Together, they force the court to examine the real legal basis of the underlying action, rather than merely how creatively the complaint is worded.

Louisville v. Mottley: What exactly did the Supreme Court hold in Mottley?

The Supreme Court therefore reversed the judgment and instructed the lower federal court to dismiss the lawsuit for want of jurisdiction.

The Mottleys' own cause of action arose under state contract law. The federal statute and Fifth Amendment issues appeared only because the Mottleys anticipated LNRC's federal defense and attempted to answer it in their complaint.

Louisville v. Mottley: Did the Supreme Court in Mottley decide whether the federal statute actually prohibited the Mottleys’ lifetime passes?

No. The Court did not decide:

• whether the statute actually covered these particular passes; or

• whether applying the statute to the Mottleys would violate the Fifth Amendment.

It stopped before reaching either merits question because the federal court lacked subject-matter jurisdiction to adjudicate the case in the first place.

What are the essential facts and background of Grable & Sons Metal Products, Inc. v. Darue Engineering & Manufacturing?

Grable owed federal taxes, and the IRS seized Grable’s Michigan property and sold it to Darue. Although Grable actually received notice of the seizure by certified mail, Grable later argued that the IRS had not provided notice in the manner required by 26 U.S.C. § 6335(a).

Grable therefore sued Darue, claiming that the defective federal notice made the tax sale - and consequently Darue’s title - invalid, leaving Grable with superior title to the property.

Grable v. Darue: What is a quiet-title action, and why is that important in Grable?

A quiet-title action asks a court to determine which party has the valid or superior ownership interest in property.

Grable's quiet-title action was created by Michigan state law.

Cause of action: Michigan quiet-title law.
Embedded issue: Whether the IRS complied with federal tax law.

Grable v. Darue: Where did Grable originally file the lawsuit, and what happened next?

Grable filed its quiet-title action in Michigan state court.

Darue then removed the case to federal district court under 28 U.S.C. § 1441(a).

Darue's theory was that the federal district court had original federal-question jurisdiction under § 1331 because Grable's own quiet-title claim necessarily depended upon resolving a disputed question of federal tax law.

Grable wanted the case returned to state court, but the district court refused to remand it.

Grable v. Darue: Why was 28 U.S.C. § 1441(a) important in Grable?

Section 1441(a) generally allows a defendant to remove a state-court action if the plaintiff could originally have brought that action in federal district court.

So the removal question depended on § 1331:

Could Grable originally have filed this quiet-title action in federal court as a case “arising under” federal law?

If yes → Darue could remove.

If no → the federal court lacked subject-matter jurisdiction and had to remand the case to Michigan state court.

What is the cleanest comparison between Mottley and Grable?

The Mottleys could establish breach using state contract law alone. Federal law appeared only because they anticipated the railroad saying federal law prohibited the passes. → No § 1331 jurisdiction.

Grable cannot establish its own theory of superior title without resolving federal law. → The federal question appears within the plaintiff's well-pleaded complaint and can potentially support § 1331 jurisdiction.

Louisville v. Mottley: If Mottley could not be heard originally in federal court, who could decide the federal issue when the railroad raised it?

The state court. State courts are fully competent to interpret and apply federal law.

The railroad could raise the federal prohibition as a defense in state court, and the state court could decide whether that federal statute prevented enforcement of the Mottleys' contract.

A federal defense does not create § 1331 jurisdiction or permit removal.

Any eventual federal review would proceed through the appellate system and could potentially reach the U.S. Supreme Court.

If a state court could decide federal law in Mottley, why couldn't Michigan state court decide § 6335(a) in Grable?

It could.

The Supreme Court never held that Michigan courts were incapable of deciding the federal issue.

The question was whether federal courts also had original jurisdiction over Grable's claim.

What was Smith v. Kansas City Title & Trust Co., and why is it important to Grable?

Smith established that a case can sometimes “arise under” federal law even though state law creates the plaintiff's cause of action.

The plaintiff brought a state-law claim involving a corporation's proposed purchase of federally authorized bonds. But whether the plaintiff could obtain relief depended upon whether the federal law authorizing those bonds was constitutional.

The Supreme Court found federal jurisdiction because the federal issue was necessary and substantial.

Thus, Smith provided longstanding precedent for embedded federal-question jurisdiction.

What was Merrell Dow Pharmaceuticals Inc. v. Thompson?

In Merrell Dow, the plaintiffs sued a drug manufacturer under state tort law, alleging that the drug caused injuries. One of their theories was that Merrell Dow had violated the federal Food, Drug, and Cosmetic Act (FDCA) by misbranding the drug, and that this federal violation supported their state-law negligence claim.

However, Congress had not created a private federal cause of action allowing the plaintiffs to sue directly for that FDCA violation. The Supreme Court held that the embedded FDCA issue did not create § 1331 federal-question jurisdiction.

Did Merrell Dow establish “no federal cause of action = no federal jurisdiction”?

No. That is precisely the interpretation Grable rejects.

The absence of a federal cause of action is relevant evidence, particularly regarding congressional intent, but it is not automatically fatal to § 1331 jurisdiction.

One major reason is Smith.

Smith allowed federal jurisdiction over a state-law cause of action containing a substantial federal issue, and Merrell Dow itself had approved rather than overruled Smith.

What is the Grable test for a state-law claim containing an embedded federal issue?

A state-law claim can support § 1331 jurisdiction when the federal issue is:

1. Necessarily raised;

2. Actually disputed;

3. Substantial; and

4. Capable of resolution in federal court without disrupting the congressionally approved federal-state balance.

All four considerations matter.

Importantly, substantiality and federalism are separate inquiries. A substantial federal question does not simply “override” federalism.

Why was the federal issue “necessarily raised” in Grable?

Because under Grable's chosen theory of superior title, Grable could not win without establishing that the IRS violated § 6335(a).

IRS failed to provide legally sufficient notice → tax sale was defective → Darue's resulting title is defective → Grable has superior title.

Thus, resolving the federal notice question was necessary to Grable's affirmative claim, rather than merely something that might arise later.

Why was the federal issue “actually disputed” in Grable?

The parties genuinely disagreed about what § 6335(a) required.

Grable argued that the federal statute required a particular form of service and that certified mail was insufficient.

Why was the federal issue “substantial” in Grable?

The federal issue mattered beyond the immediate dispute between Grable and Darue.

The case concerned the proper operation of the federal tax-collection system - specifically, what procedures the IRS must follow when seizing property.

A clear interpretation of § 6335(a) could guide future understanding of the IRS's federal tax-sale procedures and affect the reliability of property titles produced through those procedures.

So the issue implicated an important federal governmental interest, not merely two private litigants.

Why did exercising federal jurisdiction in Grable not improperly interfere with federalism?

Cases like Grable were expected to be rare. Quiet-title actions containing genuinely disputed and substantial questions about federal tax-sale procedures would not suddenly flood federal courts.

Thus, allowing this narrow category into federal court would have only a small effect on the traditional allocation of cases between state and federal courts.

That distinguishes Grable sharply from Merrell Dow, where the jurisdictional theory could have swept a huge number of ordinary state tort cases into federal court.

Why does Grable come out differently from Merrell Dow even though neither plaintiff had a federal cause of action?

In Merrell Dow, the alleged FDCA violation was only one theory supporting the plaintiffs’ state-law tort claims. The plaintiffs had multiple other state-law theories on which they could potentially recover. Thus, resolving the federal issue in their favor was not necessary to winning the overall case.

In Grable, by contrast, the federal issue was necessary to Grable’s theory of recovery. Grable claimed superior title specifically because the IRS violated § 6335(a). If Grable could not establish the federal violation, that theory of superior title failed.

There was also a federalism difference: allowing federal jurisdiction over FDCA-based tort theories could pull a large number of ordinary state tort cases into federal court, whereas quiet-title cases turning on disputed federal tax-sale procedures would be rare.

Could Grable originally have filed its quiet-title action directly in federal court?

Yes.

That follows from the Supreme Court's ultimate jurisdictional holding.

Although Michigan law created the cause of action, the embedded federal issue satisfied the requirements for § 1331 jurisdiction.

Therefore, the federal district court had original jurisdiction.

What is the relationship among §§ 1331, 1441(a), and 6335(a) in Grable?

Each statute plays a different role:

§ 6335(a): Supplies the substantive federal issue - what notice the IRS had to provide.

§ 1331: Determines whether that embedded federal issue makes the action one “arising under” federal law, giving the district court original jurisdiction.

§ 1441(a): Allows Darue to remove the case from state court because the district court had original jurisdiction.

What is the basic dispute in T. B. Harms Co. v. Eliscu?

The case is fundamentally a copyright ownership dispute. Harms claimed that Edward Eliscu had already transferred his rights in certain songs - including his renewal rights - to Max Dreyfus, who was acting for Harms. Eliscu later claimed that he still owned part of the renewal copyrights and transferred his claimed interest to Ross Jungnickel, Inc.

The practical question was therefore: Did Eliscu already transfer away his rights, or did he retain renewal rights that he could later claim and transfer?

Why does Harms fail Holmes's creation test? If the copyright itself is created by federal law, why isn't a dispute over who owns it automatically federal?

Because federally created property is not the same thing as a federally created cause of action.

Federal law creates copyrights. But private parties can later enter contracts assigning those rights.

A dispute over what an assignment meant, whether a transfer occurred, and who received the rights can be governed by ordinary state contract/property principles.

Harms v. Eliscu: Despite his claim failing the Holmes test, why did Harms still believe this lawsuit belonged in federal court?

A claim created by state law can nevertheless arise under federal law when resolving that claim necessarily requires deciding an appropriate federal-law issue.

The embedded federal question in this case was whether a lawsuit concerning ownership and assignment of federally created copyrights necessarily “arises under” federal copyright law for purposes of 28 U.S.C. § 1338.
