1. Subject Matter Jurisdiction
A federal court must have subject matter jurisdiction. The two principal bases are federal question jurisdiction and diversity jurisdiction. Because the complaint alleges only state-law negligence, only diversity is available.
Complete Diversity
Diversity jurisdiction requires complete diversity—no plaintiff may share citizenship with any defendant. A natural person is a citizen of the state of his domicile. A corporation is a citizen of every state where it is incorporated and the state of its principal place of business under the nerve-center test.
Plaintiffs Peggy and Owen are "lifelong residents of California," so both are domiciled in California. Defendant Dan is "a citizen of Nevada." Defendant NBL is "Nevada Bus Lines, Inc."—a Nevada corporation whose facts strongly suggest its principal place of business is Nevada. There is complete diversity: California plaintiffs versus Nevada defendants.
Amount in Controversy
The amount in controversy must exceed $75,000. Peggy alone seeks $100,000 (medical expenses and pain and suffering), which clears the threshold. Owen seeks $50,000 for property damage, which does not.
A single plaintiff may aggregate all claims against a single defendant, but two plaintiffs cannot aggregate their claims against a common defendant unless they assert a common, undivided interest. Peggy and Owen have separate, individual claims, so Owen cannot aggregate with Peggy.
However, supplemental jurisdiction allows a federal court to hear claims that form part of the same case or controversy as a claim within the court's original jurisdiction. The Supreme Court has held that supplemental jurisdiction extends to additional plaintiffs' claims that fail to meet the amount-in-controversy requirement, so long as at least one plaintiff satisfies the amount and complete diversity is preserved. Owen's claim arises from the same accident as Peggy's, and complete diversity is preserved. Owen's $50,000 claim therefore comes in by supplemental jurisdiction.
The federal court has subject matter jurisdiction over both claims.
2. Personal Jurisdiction
Personal jurisdiction requires both a basis under the forum state's long-arm statute and consistency with constitutional due process. California's long-arm statute extends to the full limit of due process. Due process requires that the defendant have minimum contacts with the forum such that exercise of jurisdiction does not offend traditional notions of fair play and substantial justice.
NBL
NBL operated a bus that transported "master bingo players from Thousand Oaks, California, to a bingo tournament." NBL therefore purposefully availed itself of the California market by routing buses into California. The accident occurred in Los Angeles, California. Specific personal jurisdiction exists where the defendant's purposeful contacts with the forum gave rise to the claim. NBL transported passengers into California, and the alleged tort occurred in California. The claim arises out of and relates to NBL's California contacts. Specific jurisdiction over NBL is proper.
Dan
Dan was driving the bus into California in the course and scope of his employment when he caused the accident. By voluntarily driving into California and committing a tort there, Dan purposefully directed his conduct at California. A defendant who drives into a forum and causes injury there is subject to specific jurisdiction in that forum. Personal jurisdiction over Dan is also proper.
The exercise of jurisdiction over both defendants is fair: California has a strong interest in adjudicating accidents that injure its residents on its highways, plaintiffs have an interest in litigating at home, and Nevada is geographically adjacent. There is no due-process violation.
3. Service of Process on Dan
Under the federal rules, an individual within a judicial district of the United States may be served by:
(1) Following the law of the state where the district court sits (California) or the state where service is made (Nevada); or
(2) Doing any of the following: (a) delivering a copy of the summons and complaint to the individual personally; (b) leaving a copy at the individual's dwelling or usual place of abode with someone of suitable age and discretion who resides there; or (c) delivering a copy to an authorized agent.
Larry "slid a copy of the complaint under the front door of Dan's house" when no one was home. This satisfies none of the federal alternatives: it is not personal delivery; it is not delivery to a person of suitable age and discretion residing at the dwelling; and it is not delivery to an authorized agent. Both California and Nevada law similarly require either personal service or substituted service that involves leaving the papers with another person and following up with mailing. Sliding papers under a door is not authorized by either state.
The fact that Dan eventually received the complaint when he came home does not cure improper service. Actual notice does not substitute for compliance with the rules on service of process. Dan was not properly served. (Dan's filing of an answer without raising the defense of insufficient service may, however, waive the objection if not raised in the answer or by pre-answer motion.)
4. Motion to Compel — Document Production
Under the federal rules, parties may obtain discovery regarding any nonprivileged matter that is relevant to any party's claim or defense and proportional to the needs of the case. Proportionality factors include the importance of the issues, the amount in controversy, the parties' relative access to information, the parties' resources, the importance of the discovery in resolving the issues, and whether the burden or expense outweighs the likely benefit.
Plaintiffs request "all documents from the past 10 years related to claims for injuries and property damage caused by NBL's drivers." This is a broad request. Whether it should be granted depends on the underlying claim against NBL.
Relevance
Plaintiffs allege NBL is liable as Dan's employer—presumably under respondeat superior. For respondeat superior, the only relevant facts are that Dan was an employee acting within the scope of employment. Prior accidents by other drivers are not relevant to that theory.
If, however, plaintiffs assert (or amend to assert) negligent hiring, training, supervision, or retention, then prior accidents become highly relevant: they tend to show notice to NBL of a pattern of unsafe driving and the foreseeability of accidents like this one.
Proportionality and Scope
Even where relevance exists, the ten-year, all-driver scope is broad. A court would likely narrow the request—for example, to a more limited time period (such as three or five years) and to incidents involving similar conduct (driver fatigue, falling asleep, collisions). Courts routinely tailor overbroad discovery rather than denying it outright.
Ruling
The court should grant the motion in part. To the extent plaintiffs assert a negligent-supervision-type theory, prior NBL driver-caused incidents are relevant, and some discovery should be permitted. The court should narrow the request to a reasonable time frame and to incidents involving similar driver-error conduct, balancing relevance against burden. To the extent plaintiffs assert only respondeat superior, the request is largely irrelevant and should be denied as disproportionate.
