1. Venue
The court has diversity jurisdiction if the parties are completely diverse and more than $75,000 is genuinely in controversy. Shearer is a Nevada citizen and Jiff a California citizen; the claimed $100,000 vase value meets the amount requirement absent a legal-certainty problem. The Nevada contract does not turn the suit into a federal-question case, but diversity supplies the stated federal forum.
Under 28 U.S.C. section 1391(b)(1), venue is proper in a district where any defendant resides if all defendants reside in the same state. For a natural person, residence for this purpose is domicile. Jiff is the only defendant and is described as a California citizen residing in Truckee, within the Eastern District. That supports his domicile and makes venue proper there.
A substantial-events district under subsection (b)(2) is another permissible basis, not a requirement overriding defendant-residence venue. Nevada is where the contract was signed, the work performed, and the vase broken, so a Nevada forum also may be proper. Those facts do not make the Eastern District improper. A convenience transfer analysis would consider private and public factors, but is distinct from whether the chosen district is authorized. The proximity of Truckee and Reno further cautions against assuming a dramatic inconvenience on these facts.
2. The customer evaluations
Federal discovery procedure governs in this federal action. Rule 26(b)(1) permits discovery of nonprivileged information relevant to a claim or defense and proportional to the case’s needs. Discoverable information need not itself be admissible at trial. Rule 34 reaches responsive documents within a party’s possession, custody, or control, subject to a proper request and the motion-to-compel prerequisites.
Jiff requested evaluations in the ordinary course of his cleaning business to monitor satisfaction. Reviews of his cleaning practices can reveal recurring carelessness, methods, relevant admissions, or witnesses familiar with his practices. They need not already establish the cause of this particular broken vase to be discoverable. Conversely, customer opinions about unrelated features such as price or punctuality may have little bearing, and different premises and accidents may require narrowing by subject.
The one-year limit and the substantial claimed loss support a proportionate request on the facts given; no exceptional volume, expense, privacy burden, or missing control is identified. Jiff can seek appropriate redaction, narrowing, or protection for genuinely unrelated confidential details rather than automatic withholding of the entire set.
These are ordinary business records, not materials created in anticipation of litigation. Jiff’s desire to improve his services does not make them attorney-client communications or work product. Nor does a possible hearsay or character objection at trial categorically defeat discovery. Prior mistakes do not automatically prove present negligence, but the discovery standard is broader than that proposed evidentiary use.
Accordingly, assuming Shearer served an appropriate request and satisfied the necessary conferral and procedural requirements, a blanket denial for lack of admissibility or presumed protection likely was error. A judge retains discretion to limit irrelevant or disproportionate portions; the question supplies no particular procedural defect or burden justifying total denial. The older phrase “reasonably calculated to lead to admissible evidence” should not replace the operative relevance-and-proportionality standard.
3. Effect of the first judgment
Claim preclusion
Claim preclusion ordinarily requires a final valid merits judgment, the same parties or qualifying privies, and the same claim. A jury trial followed by judgment for Jiff is a merits judgment. Shearer did not appeal; it is not a dismissal reserving a later contract action. Both suits involve exactly the same opposing parties and the same alleged failure of due care causing the same vase damage.
Changing the legal label from negligence to breach of contract does not ordinarily authorize splitting a single claim into successive suits. Shearer could have joined the contract theory in the first action; the same federal diversity jurisdiction and transaction were present. Shearer cannot avoid the judgment by saying that a different source of the same due-care obligation now is invoked.
The preclusive effect of a federal diversity judgment is governed by federal common law, which under Semtek generally incorporates the preclusion law of the forum state unless incompatible with federal interests. California uses a primary-right approach rather than simply labeling every factual transaction one claim. Even under that approach, the single injury to Shearer’s property and the alleged breach of due care ordinarily implicate the same primary right despite alternative tort and contract theories. Under the federal transactional formulation the result likewise is preclusion. Jiff therefore has a strong defense to the entire second action.
Issue preclusion
Issue preclusion separately requires an identical issue actually litigated and necessarily decided in a final judgment, with a full and fair opportunity for the bound party to litigate. A finding that Jiff exercised due care could matter in the contract case, but a general verdict for him does not reveal that this was the actual necessary finding.
The jury could have found an absence of negligence, causation, compensable damage, or another defense. Without instructions, special findings, or a record showing which issue necessarily supported the verdict, Jiff cannot confidently assert that a specific disputed issue was conclusively resolved. That evidentiary uncertainty weakens issue preclusion, while leaving claim preclusion available because it does not require identifying the particular reason for the defense verdict.
