Key Court Decisions

A selection of the federal rulings Brent has secured on behalf of claimants against insurers — the record his litigation strategy is built on.

Cobb v. Chevron Corp. No. 24-cv-03851-SK · N.D. Cal. 2025

Two decisive rulings in the same ERISA long-term disability case. First, on summary judgment, the court found Chevron never properly delegated discretionary authority to its claims administrator, ReedGroup — stripping the denial of deferential review and forcing de novo review instead. Then, after a bench trial, the court entered judgment for Mr. Cobb, rejecting ReedGroup's attempt to reclassify his documented traumatic brain injury as a "mental illness" to trigger the plan's 24-month benefits cap.

The question: can a claims administrator reclassify a documented traumatic brain injury as a mental illness to cut off benefits early? The answer: no — not when MRI, PET, and vestibular testing point to a physical, neurological injury, and the administrator's own treating psychiatrist agrees the cause isn't psychological.

The court also faulted the administrator for terminating benefits without ever performing the vocational analysis its own plan required, crediting the comprehensive treating-team record over a single non-specialist paper review.

Waldron v. Unum Life Ins. Co. of America 773 F. Supp. 3d 1169 · W.D. Wash. 2025

Trial judgment for a plaintiff who developed chronic, debilitating fatigue, brain fog, and headaches after a COVID-19 vaccination. Unum denied his LTD claim, arguing the medical record lacked objective evidence of disability. The court disagreed, finding Unum's own plan did not require objective proof and that the record — extensive specialist visits, a Mayo Clinic evaluation, and neuropsychological testing ruling out malingering — supported disability by a preponderance of the evidence.

The question: can a claimant prove disability from a condition medicine can't objectively test for through subjective symptoms alone? The answer: yes, when corroborated by consistent treatment records and treating-physician judgment, especially where the plan itself imposes no objective-evidence requirement.

The court also barred Unum from relying on a new rationale — that the plaintiff hadn't disproven part-time work capacity — that it never raised during the claims process, applying the Ninth Circuit's rule that insurers can't invent new justifications for a denial once litigation begins.

Sze v. Brighthouse Life Insurance Company N.D. Cal. 2019

Brent secured a court order requiring Brighthouse Life to deposit $250,185.62 in disputed benefits, plus $13,181.01 in accrued interest — a total of $263,366.63 — into the Registry of the Court.

Elliott v. Life Insurance Co. of North America 2019 WL 2970843 · N.D. Cal. 2019

Trial judgment for a plaintiff disabled by trigeminal neuralgia. Judge Maxine M. Chesney found the legal arguments and medical evidence compelled a finding of disability.

Result: judgment for the plaintiff — the medical record and legal argument together left no room for a contrary finding.

Harris v. Life Ins. Co. of North America 419 F. Supp. 3d 1169 · N.D. Cal. 2019

Brent successfully defended ERISA fiduciary claims against dismissal, allowing a surviving spouse to pursue relief after her husband lost life insurance coverage due to his employer's failures.

The question: can an ERISA fiduciary be liable for failing to notify a terminally ill employee about conversion rights — especially after accepting late premiums and promising follow-up? The answer: yes, if the fiduciary's conduct misleads the participant and causes harm.

The court found the complaint plausibly alleged breaches of fiduciary duty through misrepresenting coverage status, failing to provide required information, and accepting premiums after coverage lapsed — preserving claims for equitable relief, including surcharge, under § 1132(a)(3).

Holmgren v. Sun Life and Health Ins. Co. 354 F. Supp. 3d 1018 · N.D. Cal. 2018

Brent obtained judgment for a corporate tax director whose LTD benefits were denied over chronic, degenerative back conditions and persistent pain. The court found Sun Life improperly relied on non-examining consultants and discredited treating physicians without justification, and erred in demanding objective evidence for a condition — chronic pain — that is inherently subjective but credibly documented.

The question: can a claimant prove disability despite limited "objective" findings? The answer: yes, when supported by credible subjective complaints, longitudinal medical history, and treating physician testimony.

The court also rejected arguments based on surveillance footage, social media activity, and a self-assessment performance review as insufficient to rebut the medical evidence.

Harder v. Bristol-Myers Squibb Co. Long Term Disability Plan 281 F. Supp. 3d 939 · C.D. Cal. 2017

Trial judgment for a plaintiff in a "full" abuse-of-discretion case involving disability due to depression, anxiety, PTSD, and physical disorders. Brent had handled the administrative appeal prior to litigation.

Result: Judge Percy Anderson agreed that Aetna had continually shifted its rationale for the denial as prior reasons were disproven, and that its termination of benefits was illogical.

Roberts v. Anthem Life Insurance Co. 2017 WL 2469354 · C.D. Cal. 2017

Judge granted the plaintiff's motion for remand in a case involving disability from a traumatic brain injury, agreeing that Anthem had committed several procedural irregularities warranting further consideration of the claim.

Result: on remand, the claim was approved, and counsel negotiated a settlement on additional attorneys' fees.

Leetzow v. Metropolitan Life Ins. Co. 2016 WL 7324092 · C.D. Cal. 2016

Trial judgment for a former director of sales management disabled by chronic migraines and frequent headaches — able to work when headache-free, unable to work reliably otherwise. MetLife argued there was no objective evidence of disability.

Result: the court agreed that her disability stemmed from an inability to consistently attend work when a migraine struck — not from any single incapacitating episode.

LaVertu v. Unum Life Ins. Co. of America 2014 WL 1224736 · C.D. Cal. 2014

Trial judgment for a plaintiff following three spine surgeries, establishing that sedentary work requires more than "frequent" sitting as the Department of Labor defines the term.

Result: the court also found that part-time work capacity was not a valid basis for terminating benefits.

Mondolo v. Unum Life Ins. Co. of America 2013 WL 178711 · C.D. Cal. 2013

Trial judgment for a plaintiff with fibromyalgia and avascular necrosis, establishing that she was disabled from sedentary work.

Result: the court found Unum's structural conflict of interest was a factor leading to the termination of benefits.

Lee v. West Coast Life Ins. Co. 688 F.3d 1004 · 9th Cir. 2012

The Ninth Circuit reversed summary judgment for the insurer, holding that interpleader does not shield a negligent insurance company from liability for creating the very dispute it seeks to interplead.

The question: Can a stakeholder escape tort liability by filing interpleader? The answer: No — not if its own negligence caused the conflict.

The ruling revived claims for $290,000 in lost benefits and litigation costs, reinforcing that insurers must exercise due care when processing beneficiary changes.

Peterson v. AT&T Umbrella Ben. Plan No. 1 2011 WL 5882877 · N.D. Cal. 2011

Trial judgment for the plaintiff in a self-funded, "full" abuse-of-discretion case involving chronic fatigue syndrome and the plaintiff's efforts to adopt a child.

Porco v. Prudential Ins. Co. of America 682 F. Supp. 2d 1057 · C.D. Cal. 2010

Brent secured a federal court victory for a client whose long-term disability benefits had been wrongly terminated after years of documented spinal impairment and severe pain. Despite multiple treating neurologists confirming the disabling condition, Prudential relied on limited video surveillance and flawed file reviews to justify cutting off benefits.

Result: the court conducted a de novo review, found the client remained totally disabled under the plan's terms, and ordered retroactive reinstatement of benefits with prejudgment interest — rejecting the insurer's reliance on surveillance over medical evidence.
