Louisville & Nashville Railroad Co. v. Mottley vs. Strawbridge v. Curtiss
A side-by-side comparison of two landmark civil procedure cases
Louisville & Nashville Railroad Co. v. Mottley
211 U.S. 149 (1908) (1908)
Holding
The Supreme Court held that the federal court lacked jurisdiction. Federal question jurisdiction under the predecessor to Section 1331 requires that the federal issue appear as part of the plaintiff's own cause of action as set forth in a well-pleaded complaint. A plaintiff's anticipation of a federal defense, even an anticipated constitutional challenge, does not create federal question jurisdiction.
Doctrine Established
Well-Pleaded Complaint Rule
Strawbridge v. Curtiss
7 U.S. (3 Cranch) 267 (1806) (1806)
Holding
Chief Justice Marshall held that diversity jurisdiction requires complete diversity: every plaintiff must be a citizen of a different state from every defendant. Because some parties on both sides shared citizenship in the same state, the federal court lacked jurisdiction.
Doctrine Established
Complete Diversity Rule
Comparison Analysis
Louisville & Nashville Railroad v. Mottley (1908) and Strawbridge v. Curtiss (1806) are the foundational cases on the two primary bases of federal subject matter jurisdiction: federal question jurisdiction and diversity jurisdiction, respectively. Mottley established the well-pleaded complaint rule for federal question jurisdiction, holding that a federal question must appear on the face of the plaintiff's complaint as part of the plaintiff's own cause of action -- anticipated federal defenses or counterclaims do not create federal question jurisdiction, even if everyone knows the case will turn on a federal issue. Strawbridge established the complete diversity rule for diversity jurisdiction, holding that every plaintiff must be a citizen of a different state from every defendant.
Both rules serve as threshold gatekeeping mechanisms that determine which cases can be heard in federal court. Mottley's well-pleaded complaint rule prevents plaintiffs from manufacturing federal question jurisdiction by anticipating defenses, and it prevents defendants from removing cases to federal court based on their own federal defenses. Strawbridge's complete diversity rule prevents parties from using diversity jurisdiction when any plaintiff shares citizenship with any defendant, ensuring that the purpose of diversity jurisdiction (protecting out-of-state parties from local bias) is served only when the alignment of parties is truly cross-state.
Both rules have been criticized as overly formalistic. Mottley excludes cases where the federal issue is the central dispute simply because it arises as a defense rather than as part of the plaintiff's claim. Strawbridge excludes cases with dozens of diverse parties simply because one plaintiff and one defendant happen to share citizenship. Despite these criticisms, both rules remain the governing standards, and the Supreme Court has repeatedly reaffirmed them. Students must internalize that subject matter jurisdiction is a threshold question -- if neither federal question nor diversity jurisdiction exists, the federal court must dismiss regardless of the merits.
Similarities
- Both establish foundational rules for determining federal subject matter jurisdiction under Article III and the federal jurisdictional statutes
- Both serve as threshold gatekeeping mechanisms that determine which cases can be heard in federal court
- Both involve formalistic rules that sometimes exclude cases with genuine connections to federal courts
- Both are among the first cases taught in Civil Procedure and remain the governing standards for their respective jurisdictional bases
Differences
- Mottley addresses federal question jurisdiction (28 U.S.C. Section 1331), while Strawbridge addresses diversity jurisdiction (28 U.S.C. Section 1332)
- Mottley's well-pleaded complaint rule focuses on the content of the plaintiff's complaint, while Strawbridge's complete diversity rule focuses on the citizenship of the parties
- Mottley can be circumvented if the plaintiff is able to frame the complaint to raise a federal cause of action, while Strawbridge's rule is rigid -- complete diversity either exists or it does not
- Mottley involves the interpretive question of what constitutes a federal question, while Strawbridge involves the factual question of parties' state citizenship
- Mottley was decided in 1908 interpreting the general federal question statute, while Strawbridge was decided in 1806 by Chief Justice Marshall interpreting the original Judiciary Act
Why This Comparison Matters
Subject matter jurisdiction is always tested on Civil Procedure exams. Every analysis should begin by asking: is there federal question jurisdiction under Mottley's well-pleaded complaint rule (does the plaintiff's claim itself arise under federal law?) or diversity jurisdiction under Strawbridge's complete diversity rule (is every plaintiff diverse from every defendant, with the amount in controversy exceeding $75,000)? Students must be disciplined about applying these rules mechanically -- many exam answers go wrong because students find federal jurisdiction based on anticipated federal defenses (violating Mottley) or allow minimal diversity (violating Strawbridge).

Pennoyer v. Neff vs. International Shoe Co. v. Washington
Pennoyer v. Neff (1878) and International Shoe Co. v. Washington (1945) represent the most important paradigm shift in personal jurisdiction doctrine. Pennoyer established the territorial model: a court's jurisdiction over a defendant required either physical presence within the state's borders or voluntary appearance. This framework treated jurisdiction as a question of sovereignty -- each state's power ended at its borders, and due process required that the defendant be physically present or have property within the jurisdiction. International Shoe replaced this rigid territorial approach with a flexible contacts-based test: due process requires only that the defendant have 'minimum contacts' with the forum state such that the exercise of jurisdiction does not offend 'traditional notions of fair play and substantial justice.'
World-Wide Volkswagen Corp. v. Woodson vs. Ford Motor Co. v. Montana Eighth Judicial District Court
World-Wide Volkswagen v. Woodson (1980) and Ford Motor Co. v. Montana Eighth Judicial District Court (2021) both address specific personal jurisdiction over out-of-state defendants in product liability cases, but they reach different results that illustrate the evolution of the doctrine. World-Wide Volkswagen held that an Oklahoma court lacked jurisdiction over a New York car dealer and regional distributor in a product liability suit, because the defendants had no contacts with Oklahoma -- the plaintiffs had unilaterally driven the car there. Ford Motor held that Montana and Minnesota courts had jurisdiction over Ford in product liability cases involving accidents in those states, even though the specific vehicles involved were not sold or originally delivered in those states.
Erie Railroad Co. v. Tompkins vs. Hanna v. Plumer
Erie Railroad Co. v. Tompkins (1938) and Hanna v. Plumer (1965) together form the analytical framework for the Erie doctrine -- the rules governing when federal courts sitting in diversity must apply state law and when they may apply federal law. Erie held that there is no federal general common law and that federal courts must apply state substantive law in diversity cases, overruling the century-old precedent of Swift v. Tyson. Hanna refined the Erie analysis by establishing two separate tracks: when a Federal Rule of Civil Procedure or federal statute directly conflicts with state law, the federal rule applies if it is valid under the Rules Enabling Act (Hanna's holding); when there is no directly applicable federal rule, courts apply the Erie/Guaranty Trust 'outcome-determinative' test to determine whether the issue is substantive or procedural.
Conley v. Gibson vs. Bell Atlantic Corp. v. Twombly
Conley v. Gibson (1957) and Bell Atlantic Corp. v. Twombly (2007) represent the before and after of modern federal pleading standards. Conley established the liberal 'no set of facts' standard, holding that a complaint should not be dismissed unless it appears beyond doubt that the plaintiff can prove no set of facts in support of the claim that would entitle relief. This approach was extremely permissive and allowed virtually any claim to survive a motion to dismiss so long as it gave the defendant fair notice of the claim. Twombly retired the 'no set of facts' language and replaced it with the 'plausibility' standard, requiring that a complaint contain factual allegations that, taken as true, state a claim that is plausible on its face.
