A federal court hears a diversity action involving a state-law medical-malpractice claim. State law imposes a substantive damages cap, while the Federal Rules prescribe how motions and pleadings are filed. Which law should the federal court apply? A. Federal law to both the damages cap and filing procedures B. State law to the damages cap and federal law to filing procedures C. State law to both the damages cap and filing procedures D. Federal law to the damages cap and state law to filing procedures Correct Answer: B. State law to the damages cap and federal law to filing procedures Rationale: Under the Erie doctrine, a federal court exercising diversity jurisdiction applies state substantive law and federal procedural law. A damages cap affects the parties’ substantive rights and is generally governed by state law. Filing and motion procedures are governed by valid federal procedural rules. Question 2 A corporation is incorporated in Delaware. Its executive officers direct and coordinate corporate operations from Illinois, although most of its employees and physical facilities are located in Texas. For diversity jurisdiction, where is the corporation a citizen? A. Delaware and Texas only B. Illinois and Texas only C. Delaware, Illinois, and Texas D. Delaware and Illinois only Correct Answer: D. Delaware and Illinois only Rationale: A corporation is a citizen of every state in which it is incorporated and the single state containing its principal place of business. The principal place of business is ordinarily the corporation’s “nerve center,” where senior officers direct and coordinate activities. Thus, Delaware and Illinois control. Question 3 A defendant resides in District A. The contract was negotiated, executed, and breached in District B, where most witnesses and records are located. Both districts are within different states. Which statement best describes proper venue? A. Venue is proper only in District A because the defendant resides there B. Venue is proper only where the plaintiff resides C. District B is proper because a substantial part of the events occurred there D. Venue is improper in both districts unless the defendant consents Correct Answer: C. District B is proper because a substantial part of the events occurred there Rationale: Venue is proper in a judicial district where a substantial part of the events or omissions giving rise to the claim occurred. District B therefore qualifies. Defendant residence can also support venue in appropriate circumstances, but it is not the exclusive basis. Question 4 A plaintiff files a state-law negligence action in federal court. The complaint alleges that the defendant will likely argue that a federal safety statute preempts the plaintiff’s claim. The defendant moves to dismiss for lack of federal-question jurisdiction. How should the court rule? A. Deny the motion because a federal defense is anticipated B. Deny the motion because federal preemption always creates federal jurisdiction C. Grant the motion because the federal issue does not appear in the plaintiff’s properly pleaded claim D. Grant the motion only if the parties are citizens of the same state Correct Answer: C. Grant the motion because the federal issue does not appear in the plaintiff’s properly pleaded claim Rationale: Under the well-pleaded complaint rule, federal-question jurisdiction exists only when the plaintiff’s properly pleaded complaint establishes a claim arising under federal law. A federal defense, including preemption, generally does not create jurisdiction. Diversity is irrelevant to whether federal-question jurisdiction exists. Question 5 A limited partnership has one general partner who is a citizen of Florida and three limited partners who are citizens of Georgia, Alabama, and Tennessee. In which states is the partnership considered a citizen for diversity purposes? A. Florida only B. Florida and the state where the partnership maintains its headquarters C. Florida, Georgia, Alabama, and Tennessee D. The state in which the partnership was organized only Correct Answer: C. Florida, Georgia, Alabama, and Tennessee Rationale: An unincorporated association, including a partnership, takes the citizenship of every one of its partners or members. Both general and limited partners count. The partnership’s headquarters and state of organization do not determine citizenship in the same manner as a corporation’s incorporation and nerve center. Question 6 A plaintiff brings a federal employment-discrimination claim and a related state-law contract claim arising from the same termination. Before trial, the federal claim is dismissed. What may the federal court properly do with the remaining state claim? A. It must retain the state claim until final judgment B. It may decline supplemental jurisdiction and dismiss the state claim C. It must transfer the claim to the state supreme court D. It may retain the claim only if diversity jurisdiction independently exists Correct Answer: B. It may decline supplemental jurisdiction and dismiss the state claim Rationale: A federal court may decline supplemental jurisdiction when all claims supporting original federal jurisdiction have been dismissed, particularly when dismissal occurs before trial. The court is not required to retain the state claim. Federal courts do not directly transfer claims to state supreme courts. Question 7 A defendant files an answer addressing the merits but does not object to improper venue. Two months later, the defendant moves to dismiss for improper venue. What is the likely result? A. The motion is granted because venue objections cannot be waived B. The motion is denied because the defendant waived the venue objection C. The motion is granted if the defendant shows inconvenience D. The motion is denied only if subject matter jurisdiction also exists Correct Answer: B. The motion is denied because the defendant waived the venue objection Rationale: Improper venue is a waivable defense and must be raised in the defendant’s first Rule 12 response, whether a pre-answer motion or the answer. By answering without asserting it, the defendant waived the objection. Question 8 A Texas plaintiff sues a Louisiana defendant in federal court under diversity jurisdiction. The plaintiff then seeks to assert a related state-law claim against a newly joined Texas third-party defendant. May the plaintiff rely on supplemental jurisdiction? A. Yes, because the claim arises from the same transaction B. Yes, because complete diversity is required only when the complaint is filed C. No, because plaintiffs generally may not use supplemental jurisdiction to assert claims against nondiverse parties in diversity cases D. No, unless the amount sought from the third-party defendant exceeds $75,000 Correct Answer: C. No, because plaintiffs generally may not use supplemental jurisdiction to assert claims against nondiverse parties in diversity cases Rationale: In diversity cases, supplemental jurisdiction does not ordinarily extend to certain claims by plaintiffs against parties joined under specified procedural rules when doing so would defeat complete diversity. The common-nucleus requirement alone is insufficient, and the amount in controversy does not cure the citizenship defect. Question 9 A corporation conducts extensive business in several federal districts. A lawsuit arises from activities occurring in one of those districts. For venue purposes, where may the corporation be deemed to reside? A. Only in the district containing its principal place of business B. Only in the state of incorporation C. In any district where it is subject to personal jurisdiction for that action D. In every district in the United States regardless of contacts Correct Answer: C. In any district where it is subject to personal jurisdiction for that action Rationale: A business entity is treated as residing in any judicial district where it is subject to personal jurisdiction with respect to the civil action. Corporate venue is therefore tied to relevant jurisdictional contacts. Principal place of business and incorporation are not exclusive venue locations. Question 10 A contract contains a clause selecting a particular federal district as the exclusive forum. The parties are not diverse, and the complaint raises only state-law claims. What is the effect of the clause? A. It creates federal subject matter jurisdiction B. It may establish or support venue, but it cannot create subject matter jurisdiction C. It automatically converts the claim into a federal question D. It eliminates the need for personal jurisdiction and service Correct Answer: B. It may establish or support venue, but it cannot create subject matter jurisdiction Rationale: Parties may consent to or contractually select an appropriate venue, but they cannot confer federal subject matter jurisdiction by agreement. Federal jurisdiction must arise from the Constitution and statutes. A forum-selection clause also does not automatically eliminate requirements such as personal jurisdiction or valid service. Question 11 A diversity action is filed in a proper federal venue in State X and later transferred for convenience to a federal court in State Y. Which state’s choice-of-law rules ordinarily apply after the transfer? A. State Y’s rules because it is the transferee forum B. Federal common-law rules C. State X’s rules because the original venue was proper D. Whichever rules produce the fairest outcome Correct Answer: C. State X’s rules because the original venue was proper Rationale: When a diversity case is transferred from a proper venue for convenience, the transferee court ordinarily applies the choice-of-law rules that the transferor court would have applied. This prevents a transfer from changing the governing law.
