SMJ
A court's legal power and authority to hear and decide a specific type of case or controversy
This type of personal jurisdiction allows a court to hear any and all claims against a defendant, but it requires the defendant to be effectively "at home" in the forum state
General Jurisdiction
This 1938 landmark case famously declared, "There is no federal general common law."
Erie Railroad Co. v. Tompkins
This type of federal subject matter jurisdiction requires that the plaintiff's claim arises under the US Constitution, treaties, or federal laws.
Federal Question Jurisdiction
Being served with process while physically present within the borders of the forum state establishes this traditional basis for personal jurisdiction.
Tag Jurisdiction (or Transient Jurisdiction)
The rule of "complete diversity" dictates that no plaintiff can share citizenship with [any/the] _____ in the lawsuit.
defendant
The Supreme Court in Daimler held that for a corporation, general jurisdiction usually only exists where it is _______ and the state of its ______.
Incorporated; Nerve Center / Principal Place of Business
Under the basic Erie Doctrine, a federal court sitting in diversity must apply the substantive law of this sovereign entity.
State
For a federal court to hear a case based on diversity jurisdiction, the amount in controversy must exceed this exact dollar figure
$75,000 (exclusive of interest & cost)
This 1945 Supreme Court case established that a non-resident defendant must have "minimum contacts" with the forum state so that the suit does not offend "traditional notions of fair play and substantial justice
International Shoe Co. v. Washington
(LA BAR MCQ) A tanker truck carrying chemicals spilled its load and contaminated the property of five neighboring landowners.
The landowners joined together and filed a suit against the owner of the truck in federal court based on diversity jurisdiction.
Each of the five landowners prayed for an award of $20,000 to pay for the cleanup of his property, for a total demand of $100,000.
Does the landowners’ complaint satisfy the amount in controversy requirement of diversity jurisdiction?
No, because the multiple landowners may not aggregate their separate, small claims to meet the amount in controversy requirement.
**Multiple plaintiffs generally cannot aggregate their claims with their separate, distinct claims to meet the amount in controversy requirement.**
This doctrine holds that merely placing a product into the market is not enough for PJ; the defendant must have purposefully directed the product toward the forum state.
Stream of Commerce (doctrine)
While federal courts in diversity apply state substantive law, they apply this body of codified rules for procedural matters.
Federal Rules of Civil Procedure (FRCP)
A corporation has dual citizenship for diversity purposes: the state where it is ________, and the state where it maintains this primary location, often called its "______".
incorporated; "nerve center" or Principal Place of Business (PPB)
(ClosedAI v. TalkGPT HYPO)
TalkGPT argues that the Texas federal district court lacks personal jurisdiction over it.
(b) Does the Texas federal district court have specific personal jurisdiction over Talk GPT? Explain fully.
Assuming the Texas long-arm statute reaches constitutional limits, we analyze Due Process (Sufficient Contacts and Reasonableness).
Conclusion: Yes, the Texas federal district court also has specific personal jurisdiction over TalkGPT, Inc.
Rule: Specific personal jurisdiction exists when a non-resident defendant has sufficient "minimum contacts" with the forum state and the plaintiff's claims arise out of or relate to those contacts (International Shoe Co. v. Washington; Ford Motor Co. v. Montana Eighth Judicial District Court).
Purposeful Availment: TalkGPT purposefully availed itself of Texas by establishing its sole operational office in Texas, conducting 100% of its corporate activities from Texas, and executing its competitive strategies out of Texas.
Relatedness: ClosedAI's claims allege trade secret theft, employee poaching, and tortious misconduct. The operational decisions, false communications, and solicitation acts originated from and were directed by TalkGPT's personnel working inside its Texas headquarters. Thus, ClosedAI’s state law claims directly arise out of and relate to TalkGPT’s activities conducted within Texas.
Reasonableness: Exercising specific jurisdiction in Texas easily satisfies traditional notions of fair play and substantial justice:
Burden on Defendant: Minimal to nonexistent, as TalkGPT’s sole office and operations are in Texas.
Forum State's Interest: Texas has a strong interest in regulating corporate entities operating within its borders and preventing tortious conduct originating inside Texas.
Judicial System Efficiency: Witnesses, corporate records, and physical operations of the defendant are located in Texas, making it an efficient forum.
Conclusion: Because TalkGPT purposefully availed itself of Texas, the claims relate directly to its Texas operations, and jurisdiction is fair and reasonable, specific personal jurisdiction is proper.
28 U.S.C. § 1367 allows a federal court to hear additional state claims that do not independently meet SMJ requirements, provided they share a "common nucleus of operative fact" with the federal claim.
Supplemental Jurisdiction?
(LA BAR MCQ) Sam, a Texas citizen and the owner of a Texas sports team, visits Louisiana about every three years for a weekend vacation. His only other visit to Louisiana was when he traveled there to negotiate a licensing contract with a Louisiana graphic design company. The resulting contract allowed
Sam’s sports team to use the design company’s copyrighted logo on team uniforms in exchangefor an annual licensing fee. Sam stopped making payments but continued using the logo.
The design company filed suit against Sam in a Louisiana federal court. What can the design company’s best argument be that the Louisiana federal court may exercise personal jurisdiction over Sam?
The court has specific jurisdiction because the claim against Sam arises out of his contact with Louisiana.
**when a plaintiff's claim against a defendant arises directly out of the defendant's contact with the forum state, the court may exercise this specific type of jurisdiction. **
Established in Guaranty Trust Co. v. York, this test asks whether applying a federal rule instead of a state rule would significantly change the result of the litigation.
Outcome-Determinative Test
This rule establishes that federal question jurisdiction must be apparent from the plaintiff's original cause of action, not from an anticipated defense.
Well-Pleaded Complaint Rule
(ClosedAI v. TalkGPT HYPO)
TalkGPT argues that the Texas federal district court lacks personal jurisdiction over it.
(a) Does the Texas federal district court have general personal jurisdiction over TalkGPT? Explain fully.
Assuming the Texas long-arm statute reaches constitutional limits, we analyze Due Process (Sufficient Contacts and Reasonableness).
Conclusion: Yes, the Texas federal district court has general personal jurisdiction over TalkGPT, Inc.
Rule: Under FRCP 4(k)(1)(A), a federal district court has personal jurisdiction over a defendant if the defendant would be subject to jurisdiction in a court of general jurisdiction in the state where the federal court is located. Under constitutional due process (14th Amendment), general personal jurisdiction gives a court all-purpose jurisdiction to hear any and all claims against a defendant, even if the claims do not arise out of or relate to the defendant’s activities in the forum state.
The touchstone of general jurisdiction is whether the corporate defendant is "essentially at home" in the forum state (Daimler AG v. Bauman; Goodyear Dunlop Tires Operations, S.A. v. Brown). For a corporation, the paradigm forums where it is considered "at home" are:
Its state of incorporation, and
The state where it maintains its principal place of business.
TalkGPT, Inc. is a corporate entity. While TalkGPT was incorporated in Tennessee, it conducts all of its business operations through a single office located in Texas. Because its single operating office is in Texas, Texas constitutes TalkGPT’s principal place of business (its corporate "nerve center" and physical hub of all operations).
Because Texas is TalkGPT's principal place of business, TalkGPT is "essentially at home" in Texas under the paradigm general jurisdiction standard established in Daimler. Therefore, Texas state courts—and by extension the Texas federal district court under Rule 4(k)(1)(A)—possess general personal jurisdiction over TalkGPT.
Conclusion: Because Texas is TalkGPT’s principal place of business, TalkGPT is essentially at home in Texas, and general personal jurisdiction is proper.
(ClosedAI v. TalkGPT HYPO)
Does the Texas federal district court have subject matter jurisdiction to adjudicate ClosedAI’s claims against TalkGPT? Explain fully.
Diversity Jurisdiction According to 28 U.S.C. §1332, federal courts shall have original, diversity jurisdiction over lawsuits between citizens from different states. Diversity jurisdiction exists if: (1) there is diversity of citizenship; and (2) the jurisdictional amount-in-controversy of $75,000, exclusive of interests and costs, requirement is satisfied.
(Diversity of Citizenship) In order to meet the diversity of citizenship requirement, the parties to the dispute must be completely diverse.
ClosedAI is a limited liability company. A non-corporate entity derives its state citizenship from those of its member or members. ClosedAI’s members are Carly (an individual domiciled in California) and Computer Corp (a corporation). A corporation is a citizen of its state of incorporation and principal place of business. Computer Corp is incorporated in California and has its nerve center in California. Therefore, ClosedAI is a citizen of California. TalkGPT is a corporation. It is incorporated in Tennessee and its principal place of business (sole office) is in Texas. Therefore, TalkGPT is a citizen of Tennessee and Texas.
Plaintiff, ClosedAI, is a citizen of California, whereas Defendant, TalkGPT, is a citizen of Tennessee and Texas. Because the parties are completely diverse, the diversity of citizenship requirement is met.
(Amount-in-Controversy) The amount-in-controversy requirement is met only where the matter in controversy exceeds the sum or value of $75,000.00, exclusive of interest and costs. ClosedAI seeks over $1 billion in damages in its properly pleaded complaint. These claims certainly meet the amount in controversy requirement because it cannot be said that, to a legal certainty, they amount to less than the amount in controversy.
Diversity jurisdiction exists because the amount in controversy requirement is satisfied and the parties are held to have the requisite diversity of citizenship. Because the federal court has diversity jurisdiction over Plaintiff’s lawsuit, the federal court has subject matter jurisdiction.
(DELTA CORE HYPO) Does the federal court in Louisiana have general personal jurisdiction over DeltaCore? Explain fully.
Conclusion: No, the federal court in Louisiana does not have general personal jurisdiction over DeltaCore.
Rule: General jurisdiction is all-purpose jurisdiction, meaning that a defendant may be sued in the forum on claims even when those claims do not arise out of or relate to the defendant’s activities in the forum. The touchstone of general jurisdiction is whether the defendant is "essentially at home" in the forum state. For a corporation, the paradigm forums are its place of incorporation and principal place of business. In an exceptional case, a corporation’s affiliations with another state may be so substantial as to render it essentially at home there.
DeltaCore is a corporation incorporated in Delaware and maintains its principal place of business in Texas. Therefore, its paradigm forums for general jurisdiction are Delaware and Texas, not Louisiana. To be subject to general jurisdiction in Louisiana, DeltaCore's affiliations with the state must be so substantial as to make this an "exceptional case" where it is essentially at home there. While DeltaCore entered into a massive $275 million contract with a Louisiana corporation and sent a few dozen workers to the state, the facts explicitly state that this was DeltaCore's first project in Louisiana.
A single construction project, even a lucrative and large-scale one, does not establish the continuous and systematic affiliations required to render a corporation essentially at home in a non-paradigm state.
The 1965 case Hanna v. Plumer established the "twin aims of the Erie rule": the avoidance of inequitable administration of the laws and the discouragement of this strategic plaintiff behavior.
Forum-Shopping
**TWIN AIMS: Discouragement of forum-shopping: Preventing litigants from choosing a federal court over a state court just to get a different, more favorable set of rules.
Avoidance of the inequitable administration of the laws: Preventing unfair advantages where out-of-state litigants get a different outcome in federal court than local litigants would get in state court.
(Cedar Hypo)
Describe in detail the procedure and requirements Cedar must follow to remove the case to federal court. To which federal court may the case be removed?
What objections, if any, might Jill raise to the removal? Explain fully.
Procedure and Venue: To remove the case, Cedar must file a notice of removal containing a short and plain statement of the grounds for removal, along with copies of all state court process, pleadings, and orders. It must be filed in the federal district court embracing the state court where the action is pending, which is the federal district court in Tyler, Texas. Cedar must then promptly notify Jill and the state court.
Timing and Objections: Removal must be filed within 30 days of receiving a paper from which it first becomes ascertainable that the case is removable. Cedar received the medical records and demand on January 2, 2025, and removed 25 days later, making it timely. However, Jill may object that cases removed on the basis of diversity cannot be removed more than 1 year after the commencement of the action (filed Jan 2, 2024; removed Jan 27, 2025).
Cedar can overcome this objection by demonstrating the "bad faith" exception. Jill requested extensions, provided evasive answers, and conveniently delivered the qualifying $375,000 demand exactly one year after filing the petition, strongly indicating she acted in bad faith to delay and prevent removal.
(DELTA CORE HYPO)
Does the Louisiana federal court have specific personal jurisdiction over RiverSouth?
Explain fully.
Conclusion: Yes, the Louisiana federal court has specific personal jurisdiction over RiverSouth.
Rule: Specific jurisdiction requires that the defendant have sufficient minimum contacts with the forum state. The defendant must purposefully avail itself of the benefits and protections of the forum state, or purposefully direct its activities toward the forum state, such that the defendant could reasonably anticipate being hauled into court there. Second, the plaintiff’s claim must arise out of or relate to the defendant’s forum contacts. Finally, the exercise of jurisdiction must be reasonable, meaning it must comport with traditional notions of fair play and substantial justice.
Minimum Contacts (Purposeful Availment): RiverSouth established sufficient minimum contacts with Louisiana through its affirmative conduct. RiverSouth purposefully availed itself of the forum by sending a team to Louisiana in early 2025 to install the specialized cooling infrastructure. Furthermore, RiverSouth's manager worked directly with both DeltaCore and Louisiana-based general contractors on site. By physically entering the state to perform a commercial contract and interacting with local entities, RiverSouth purposefully directed its activities toward the forum state such that it could reasonably anticipate being haled into court there.
Relatedness: The claims against RiverSouth arise directly out of its contacts with Louisiana. DeltaCore's third-party complaint seeks indemnity and contribution based on allegations that RiverSouth's cooling systems failed multiple stress tests and caused the project delays. Because the litigation stems directly from the installation work RiverSouth performed in Louisiana, the relatedness requirement is satisfied.
Reasonableness (Fair Play and Substantial Justice): Once minimum contacts and relatedness are established, the defendant must present a strong case that jurisdiction would be unreasonable. The court evaluates several factors:
Burden on the Defendant: RiverSouth is a Mississippi LLC. Given that Mississippi neighbors Louisiana, requiring RiverSouth to travel and litigate in Louisiana does not impose a substantial burden, expense, or practical difficulty.
Forum State's Interest: Louisiana has a significant interest in adjudicating this dispute because it involves a massive infrastructure project located within its borders, compliance with Louisiana environmental and electrical regulations, and alleged harm to a Louisiana-headquartered corporation.
Interstate Judicial System’s Interest: Litigating DeltaCore's third-party claims against RiverSouth in the same Louisiana forum as the main breach of contract action promotes the efficient resolution of the controversy as a whole. The evidence, the defective materials, and the location of the events giving rise to the dispute are all centered in Louisiana.
Because RiverSouth purposefully established contacts with Louisiana, the claims relate directly to those contacts, and the exercise of jurisdiction is reasonable, specific personal jurisdiction is proper.
