The Discovery Objections Series · Part 1 · Case Study · July 2026
A sophisticated, well-represented policyholder sought exactly the discovery the law allows — and lost it to a relevance objection, before the first request ever issued, because its own complaint handed the insurer the victory.
Every part of the Discovery Objections Series pairs the doctrine with a case study, and the case studies share a selection principle: each is a case the policyholder should have won. Not a case where the law was against them — a case where the law was available, the arguments existed, and the loss traces to choices that better preparation would have changed. Part 1’s study is San Diego Unified Port District v. Underwriters at Lloyd’s, No. 15-cv-00022-WQH-JLB, 2016 WL 4496824 (S.D. Cal. May 26, 2016). It is not a biased-expert case. It is something more useful: the cleanest demonstration in the modern case law of how the relevance objection — the weakest weapon in the insurer’s arsenal — becomes unbeatable when the claimant’s own complaint concedes its premise.
The Port is no naive litigant — a public entity with institutional counsel, holding liability coverage through group policies issued to twelve California port authorities. Underwriters denied its claims; the Port sued for breach, bad faith, and punitive damages. Then, in discovery, it did something ambitious and well-founded: it sought information from other insureds’ claim files — how Underwriters had handled the coverage claims of its eleven fellow group members under the very same policies. The theory is a good one. If Underwriters denied administrative-coverage claims across the membership, the Port’s denial stops looking like a judgment call and starts looking like a practice — the recognized route to statutory bad faith under Colonial Life & Accident Insurance Co. v. Superior Court, 31 Cal.3d 785 (1982). And these were not strangers under other contracts; eleven of the twelve shared the Port’s own policies. The nexus could hardly be tighter.
The magistrate judge denied the motion to compel. In full.
The court’s reasoning had a single focus, and it was not the discovery. It was the complaint. The Port had alleged bad faith in handling the Port’s claim. It had not alleged that Underwriters engaged in a pattern or practice of mishandling claims across the membership. And when the court went looking for the allegation that would make other insureds’ files relevant, it found none — the pattern was “not alleged in the complaint,” and the Port had “put nothing before this Court” suggesting a reason to believe a pattern existed.
Two failures live in that sentence: the pattern was not pleaded, and no predicate showing was proffered. Either alone might have been survivable. Together they were fatal.
They let the court do what courts almost never get to do with bias-related discovery: sustain the relevance objection outright, and characterize the requests as “tantamount to a fishing expedition.” On this record, the epithet stuck — because a request is a fishing expedition precisely when the requester cannot say what practice it is investigating or why it believes the practice exists. The Port, having pleaded no practice and proffered no predicate, could say neither. (The court added an alternative burden holding for good measure: producing the Port’s own two files had consumed more than ninety hours; the Port answered by counting the twelve insureds instead of the hours, and the court credited the hours.)
The ruling looks like a trap: to get pattern discovery you must first allege the pattern and have “reason to believe” it exists — but the evidence that would give you reason to believe is exactly what the discovery was for. Here is what the ruling does not tell you: in California, that trap is already disarmed. The Supreme Court held in Williams v. Superior Court, 3 Cal.5th 531 (2017), that requiring proof of a claim as a condition of discovery in support of that claim “is to place the cart before the horse” — relying on an insurance case directly on point, Union Mutual Life Insurance Co. v. Superior Court, 80 Cal.App.3d 1 (1978), which held that “relevancy of the subject matter does not depend upon a legally sufficient pleading” and that discovery may be used “to get information necessary to plead a cause of action.” Two honest cautions keep this in proportion: San Diego Unified was a federal court applying the Federal Rules, where the California rule is persuasive, not binding; and Union Mutual won the relevance fight but still lost part of the scope fight on burden grounds. The pleading-precondition objection is beatable; the scope and burden objections of Parts 2 and 3 are the ones that survive. The lesson is not to hope for a generous court but to deny a strict one anything to work with.
| Plead the pattern | A properly framed set of allegations that Underwriters engaged in a general business practice of denying administrative-coverage claims across the program would have given the discovery something to attach to. The court’s first line — “not alleged in the complaint” — could never have been written. Pleading the pattern costs nothing when the facts support it; the omission was not curable at the hearing. |
|---|---|
| Build the predicate first | The winning template: name the specific practice under investigation; marshal the facts already in the record that suggest it (the insurer’s own guidelines and stated positions, objective defects in your own file); explain how the requested files will confirm or refute it. The Port had the raw material — its denial, the shared policy language, its own two files — and assembled none of it. |
| Architect the nexus | Even with the pleading fixed, the requests swept too wide — all coverage claims, both policy programs, no temporal limit. The Port’s strongest ground (eleven fellow insureds under the same instrument) was diluted by stapling it to a weaker program of individually negotiated policies, handing the court an easy limiting argument. Lead with your best nexus; do not staple your weakest to it. |
For the biased-expert practitioner the translation is direct. The complaint that supports expert-bias discovery pleads the scheme — that the insurer knowingly retains outcome-oriented experts, systematically, and that this denial was its product. The predicate is assembled from your own file: the adverse report and its visible defects, the retention channel, the expert’s known history. And the nexus is architected in the requests themselves — this expert, this claim type, this window — the tightest key available, and in expert-bias discovery the same-expert key almost always is.
