Introduction
Civil Procedure begins with power. Before a federal court considers whether the complaint states a claim, whether the defendant was properly served, whether venue is convenient, or whether discovery should proceed, the court must possess authority to hear the type of dispute presented. That authority is called subject-matter jurisdiction.
This requirement reflects a fundamental feature of the federal judicial system: federal courts are courts of limited jurisdiction. They do not possess general authority to hear every civil dispute. Their jurisdiction must arise from the Constitution and from a congressional grant authorizing the particular category of case. That limitation makes subject-matter jurisdiction one of the first issues students should examine in almost every federal Civil Procedure problem.
Subject-matter jurisdiction must also be distinguished from several doctrines that appear nearby.
- Subject-matter jurisdiction concerns the court’s authority over the category of controversy.
- Personal jurisdiction concerns the court’s authority over a particular defendant.
- Venue concerns the proper geographic location for litigation within the judicial system.
- Service of process concerns formal notice and the procedural assertion of authority over the defendant.
A court may possess subject-matter jurisdiction but lack personal jurisdiction. It may possess both forms of jurisdiction but sit in an improper venue. A lawsuit may be filed in an otherwise proper court but suffer from defective service. These concepts interact, but they are not interchangeable.
Five Major Concepts:
- Original federal-question jurisdiction.
- Original diversity jurisdiction.
- Supplemental jurisdiction.
- Removal.
- Remand.
Federal Courts as Courts of Limited Jurisdiction
State courts generally possess broad subject-matter jurisdiction. A state trial court of general jurisdiction can ordinarily hear a wide range of disputes involving contracts, torts, property, family law, business disputes, and many other matters unless some rule assigns exclusive jurisdiction elsewhere.
Federal courts operate differently. Their authority comes from constitutional and statutory sources. A federal court therefore cannot hear a dispute merely because:
- The case is important.
- The amount of money is large.
- The parties prefer a federal judge.
- The lawsuit involves parties from different cities.
- One side intends to raise federal law as a defense.
- The case would be more convenient in federal court.
A recognized jurisdictional basis must exist.
Subject-Matter Jurisdiction Cannot Be Created by Consent
One of the most important characteristics of subject-matter jurisdiction is that the parties generally cannot manufacture it by agreement.
Suppose two citizens of the same state have a purely state-law contract dispute. They may strongly prefer federal court and may even sign an agreement stating that all litigation will occur there. That agreement does not itself create federal subject-matter jurisdiction.
Similarly, a defendant does not ordinarily waive a true absence of subject-matter jurisdiction merely by failing to object at the beginning of the lawsuit. This is different from many procedural objections, which can be forfeited if not raised properly or on time.
I Federal-Question Jurisdiction
Federal district courts generally possess jurisdiction over civil actions arising under the Constitution, federal laws, or treaties. The phrase “arising under” sounds broad, but the principal examination rule is more restrictive.
The federal question ordinarily must appear on the face of the plaintiff’s properly pleaded complaint. This is the well-pleaded complaint rule.
The Well-Pleaded Complaint Rule
The starting question is: What claim is the plaintiff actually asserting? Then ask: Does federal law create that cause of action?
If the plaintiff sues under a federal civil-rights law, federal employment statute, federal antitrust law, or another federal cause of action, federal-question jurisdiction will ordinarily be straightforward.
The problem becomes harder when federal law appears somewhere in the dispute but not as part of the plaintiff’s claim. A federal defense is ordinarily insufficient.
Suppose Landlord brings a state-law eviction action against Tenant. Tenant intends to argue that eviction would violate Tenant’s federal constitutional rights. The anticipated federal defense does not transform Landlord’s state-law eviction claim into a federal-question claim. The same principle ordinarily applies even if everyone knows from the moment the complaint is filed that the federal defense will dominate the litigation. The plaintiff’s properly pleaded claim controls.
Federal Counterclaims
A federal counterclaim ordinarily does not create original federal-question jurisdiction over an otherwise state-law complaint. Suppose Seller sues Buyer in state court for breach of contract under state law. Buyer responds with a counterclaim arising under a federal statute.
The federal nature of Buyer’s counterclaim does not ordinarily retroactively convert Seller’s complaint into a federal-question case for purposes of the traditional well-pleaded complaint rule. This becomes especially important in removal analysis because removal based on federal-question jurisdiction ordinarily depends on the jurisdictional character of the plaintiff’s complaint, not a defense or counterclaim.
Exam Tip
When a problem mentions federal law, do not immediately conclude that federal-question jurisdiction exists. Circle the plaintiff’s causes of action and ask whether the federal issue appears as part of those claims rather than as a defense, counterclaim, or anticipated response.
Embedded Federal Issues
A state-law cause of action may occasionally support federal-question jurisdiction even though federal law did not create the claim. This is an exceptional category.
The state-law claim must generally necessarily raise a disputed and substantial federal issue, and federal resolution must be consistent with the proper balance between federal and state judicial responsibilities. The important word is necessarily.
If the plaintiff can prevail on the state-law claim without resolving the federal question, the argument for embedded federal-question jurisdiction becomes much weaker. Likewise, merely mentioning a federal regulation does not transform every related negligence, contract, or property action into a federal case.
Common Trap
Do not treat “federal law appears somewhere in the facts” as equivalent to “the action arises under federal law.” The well-pleaded complaint rule focuses primarily on the plaintiff’s properly pleaded cause of action.
II Diversity Jurisdiction
Diversity jurisdiction provides another major path into federal court. The traditional requirements are:
- Complete diversity of citizenship.
- An amount in controversy exceeding $75,000, exclusive of ordinary interest and costs.
Both requirements matter. A plaintiff cannot establish diversity jurisdiction by proving a sufficiently large amount while ignoring citizenship. Nor does complete diversity suffice when the amount in controversy fails to exceed the jurisdictional threshold.
Complete Diversity
Complete diversity ordinarily means that no plaintiff may share state citizenship with any defendant.
Suppose:
- Plaintiff One is a citizen of New York.
- Plaintiff Two is a citizen of Florida.
- Defendant One is a citizen of Texas.
- Defendant Two is a citizen of California.
Complete diversity exists.
Now change only one fact: Defendant Two is a citizen of Florida.
Complete diversity is destroyed because Plaintiff Two and Defendant Two share citizenship.
This is why complicated diversity problems should be solved with a citizenship chart rather than through memory. The relevant citizenship ordinarily is determined when the action is commenced. A later change of citizenship generally does not destroy diversity jurisdiction that properly existed at filing.
Citizenship of Individuals
For individuals, citizenship is based on domicile, not merely residence. Domicile generally requires: (1) Physical presence in a place, and (2) Intent to remain there indefinitely.
A person can possess many residences but ordinarily only one domicile at a time. A student may rent an apartment near law school for nine months, maintain a summer residence elsewhere, and stay periodically with family in another state. Those facts alone do not establish multiple citizenships.
Residence Is Not Citizenship: Exam questions frequently describe a party as “residing” in a state. Students often convert that statement automatically into citizenship. That is dangerous. Residence supplies evidence of physical presence but does not necessarily establish domicile. Identify whether the facts reveal an intent to remain indefinitely.
Citizenship of Corporations
A corporation is generally a citizen of:
- Every state in which it is incorporated; and
- The state where it has its principal place of business.
A corporation may therefore possess more than one citizenship. Suppose Corporation is incorporated in Delaware and has its principal place of business in Illinois. Corporation is ordinarily a citizen of both Delaware and Illinois.
The Principal Place of Business: This is ordinarily the corporation’s nerve center—the place where high-level officers direct, control, and coordinate the corporation’s activities. It is not necessarily the state with the most employees, the largest factory, or the most revenue.
Citizenship of LLCs and Partnerships
Unincorporated associations generally do not receive the corporation citizenship rule. This is a major examination trap.
- An LLC ordinarily possesses the citizenship of every one of its members.
- A partnership ordinarily possesses the citizenship of every partner.
Suppose an LLC is organized under Delaware law and maintains its headquarters in New York. Those facts alone do not determine its citizenship. If its members are citizens of Florida, Georgia, and Texas, the LLC generally takes Florida, Georgia, and Texas citizenship.
The analysis may become recursive. If one LLC member is itself another LLC, the citizenship of that entity must ordinarily be traced through its members as well.
Other Citizenship Categories
For an estate, citizenship is generally tied to the decedent for ordinary diversity analysis rather than simply to the personal representative’s personal domicile. Class litigation presents specialized statutory rules, but under traditional diversity, the citizenship of named representatives is important. Identify the legal category first, then apply the citizenship rule for that category.
Hypothetical: Citizenship
Plaintiff is domiciled in Virginia. Defendant Corporation is incorporated in Nevada and has its principal place of business in Virginia. Defendant LLC is organized in Delaware. Its only member is a citizen of Maryland.
Plaintiff cannot rely on diversity against Corporation because both Plaintiff and Corporation are Virginia citizens. The fact that Corporation is also a Nevada citizen does not cure the shared Virginia citizenship.
Defendant LLC is a Maryland citizen because its member is a Maryland citizen. Delaware organization alone does not make the LLC a Delaware citizen.
Amount in Controversy
Diversity jurisdiction ordinarily requires an amount in controversy exceeding $75,000. A claim for exactly $75,000 is therefore insufficient.
The plaintiff’s good-faith allegation ordinarily controls unless it appears to a legal certainty that the plaintiff cannot recover the jurisdictional amount. This means jurisdiction does not normally depend on the amount ultimately awarded at trial.
Aggregation
Aggregation asks whether multiple claims may be added together to satisfy the amount-in-controversy requirement.
- Single Plaintiff vs. Single Defendant: A single plaintiff may generally aggregate all claims against a single defendant, even if the claims are factually unrelated. ($45k contract claim + $40k tort claim = $85k. Rule satisfied).
- Multiple Plaintiffs: Multiple plaintiffs ordinarily cannot simply combine separate and distinct claims to cross the threshold.
- Multiple Defendants: A plaintiff likewise ordinarily cannot aggregate separate claims against multiple defendants merely to reach the threshold, unless defendants are jointly liable for one obligation.
V Supplemental Jurisdiction
Supplemental jurisdiction allows a federal court possessing original jurisdiction over at least one claim to hear additional claims that form part of the same constitutional case or controversy. The operative idea is factual relatedness. The traditional formulation asks whether the claims derive from a common nucleus of operative fact.
Suppose Plaintiff sues Police Officer under federal law for an allegedly unlawful use of force and also asserts a state-law battery claim arising from the same encounter. The federal claim supplies original federal-question jurisdiction. The battery claim arises from the same physical acts and injuries; it therefore has a strong factual relationship to the federal claim and may qualify for supplemental jurisdiction.
The Two-Step Analysis
First ask: Does statutory supplemental jurisdiction exist because the additional claim forms part of the same case or controversy?
If yes, ask: Is there a statutory restriction or discretionary reason for the federal court not to exercise it?
Diversity Restrictions
Diversity-only cases contain important statutory restrictions on certain claims by plaintiffs. The policy is to prevent plaintiffs from using supplemental jurisdiction to circumvent the complete-diversity rules. The plaintiff generally cannot use supplemental jurisdiction as a back door to achieve a party alignment that would have defeated diversity had it existed at the outset.
Discretionary Refusal
Even when supplemental jurisdiction exists, the federal court may decline to exercise it if the state-law issue is novel or complex, the state-law claim substantially predominates, or the federal claims have been dismissed. The key distinction is between power and discretion. A court may possess supplemental jurisdiction yet choose not to exercise it.
VI Removal & Remand
Removal transfers a lawsuit from state court into federal court. Removal is not itself an independent source of unlimited federal power. The normal inquiry is therefore: Could this lawsuit have been filed in federal court based on its claims and parties?
Only defendants may ordinarily remove. A plaintiff who voluntarily selected state court generally cannot later decide that federal court would be better and remove.
Rules of Removal
- Federal Question: Based on the well-pleaded complaint rule. An anticipated federal defense does not allow removal.
- Destination: The case is ordinarily removed to the federal district embracing the state court where the action was filed.
- Consent: Ordinarily requires the consent of all properly joined and served defendants (the unanimity requirement).
- Timing: Must remove within the prescribed statutory period after receiving the pleading. Diversity cases generally have a one-year overall limitation.
The Forum-Defendant Rule
A case removable SOLELY on diversity grounds generally cannot be removed when a properly joined and served defendant is a citizen of the state in which the state action was filed.
Do not write, “There is no diversity because Defendant is a citizen of the forum state.” Diversity compares plaintiffs with defendants. The forum-defendant rule separately asks whether an already-filed diversity case may be removed.
Remand
Remand sends a removed action back to state court. Students must distinguish between procedural defects and subject-matter jurisdiction defects.
Procedural Removal Defects (e.g., untimely removal, failure to obtain consent) generally must be raised within the statutory period. If the plaintiff waits too long, the objection may be forfeited.
Subject-Matter Jurisdiction Defects (e.g., parties weren't actually completely diverse) cannot be waived. The federal court lacks the asserted basis. A true jurisdictional deficiency requires remand even when an ordinary procedural objection would have been forfeited.
Chapter Summary
Subject-matter jurisdiction concerns the federal court’s authority over the category of dispute. Federal courts are courts of limited jurisdiction. Parties cannot create SMJ by agreement or waiver.
Federal-question jurisdiction generally applies to actions arising under federal law. Under the well-pleaded complaint rule, the federal issue must appear on the face of the plaintiff’s properly pleaded complaint.
Diversity jurisdiction requires complete diversity (no P shares state citizenship with any D) and an amount in controversy exceeding $75,000. Individuals are citizens where they are domiciled. Corporations are citizens where incorporated AND their principal place of business. LLCs take the citizenship of all members.
Supplemental jurisdiction permits additional claims that share a common nucleus of operative fact with claims already within original jurisdiction. Diversity-only cases contain special restrictions.
Removal transfers an action from state court to federal court, available only to defendants when original jurisdiction exists. The forum-defendant rule prevents diversity removal if a defendant is a citizen of the forum state.
Remand returns a removed action to state court. Procedural removal defects may be forfeited; true lack of SMJ cannot be waived.
