Demer isn’t just the doctrine’s home base — read as a litigation story, it shows what a claimant should have asked for, and what an insurer should have kept.
Most of this series treats Demer v. IBM Corp. LTD Plan as a doctrine machine — the case that gave courts a working four-step sequence for shifting the burden once a claimant shows a financial conflict. That is the right way to read it for the law. It is not the only useful way to read it.
Read instead as a story about what each side did — and did not do — with the record in front of them, Demer becomes something more practical: a record-building case study. Not “here is the rule.” Here is what it looks like to build, and to fail to build, the record the rule rewards.
Mr. Demer applied for long-term disability benefits. The insurer’s claim administrator relied on outside physician reviewers — doctors who never examined him, who reviewed his file on paper, and who were paid substantial sums to do a high volume of that work every year. Demer argued their volume and compensation created a financial conflict serious enough to warrant real skepticism of the denial.
The court agreed the volume-and-compensation showing was enough to raise a fair inference of conflict — modest evidence, doing real work.
Once that inference arose, the burden shifted to the insurer to answer it. The insurer could have kept records of how its reviewers’ assessments actually came out across many claims — proof, one way or the other, of whether they treated claimants evenhandedly. It did not keep those records. The court did not treat that gap kindly: it called the absence of that evidence a “missed opportunity” to negate the inference of bias, and let the inference stand largely unrebutted as a result.
That is the single most important sentence for any insurer to read in this entire body of law, and the single most important sentence for any claimant to use. An insurer that could easily have tracked its reviewers’ outcome patterns, and chose not to, does not get treated as if the question is simply unanswered. The absence itself counts against it.
Here is the part that gets skipped when Demer is cited only for its holding: the claimant did not fully develop his own record either. He did not take the kind of deposition that would have nailed down exactly how the insurer’s internal structure operated. He did not develop statistical, pattern-level evidence of his own — proof that the reviewers’ findings skewed against claimants as a group, not just proof of what they were paid.
The court’s own language is worth sitting with: both sides “ran a risk” in not developing more evidence of bias, or its absence. The claimant’s evidence was enough to win some skepticism. It was not enough to win more. A stronger record, on either side, would likely have changed the outcome’s shape.
Demer rewards exactly two things, and punishes the failure to do either:
Ask for the modest thing first. The volume-and-compensation showing did real work precisely because it did not ask for proof of actual bias — just enough structural fact to shift the question to the insurer.
Make the insurer’s silence expensive. If the insurer could have kept records showing neutrality and did not, that absence is not neutral. Name it as what it is: a missed opportunity the insurer cannot walk back.
And the mirror-image lesson for the claimant’s own side of the ledger: don’t stop at the modest showing if more is available. The claimant who also nails down the reviewer’s outcome pattern, not just the reviewer’s paycheck, wins a stronger version of the same case.
