How to Build an Appeal With the Standard-of-Review Fight in Mind
An ERISA appeal is not just about proving that a benefit denial felt unfair. It is also about building the kind of record a court may later read through a particular lens. That lens is the standard of review. In some cases, a court reviews the denial from scratch. In others, the court gives the plan administrator meaningful deference. That difference can shape what evidence matters, how clearly arguments are framed, and whether procedural problems become central later in litigation.
In this post you’ll learn how to build an ERISA appeal with that later fight in mind: what to gather, how to frame the issues, where plan language matters, and why the administrative record often becomes the whole battlefield. If you want a broader foundation first, it may help to read this overview of how courts choose the level of deference in ERISA cases.
Scroll to the bottom for every post in this series.
Why The Standard Of Review Changes The Entire Appeal
The modern framework starts with Firestone Tire & Rubber Co. v. Bruch. The Supreme Court explained that a denial of benefits under ERISA is reviewed de novo unless the plan gives the administrator or fiduciary discretionary authority to determine eligibility or construe plan terms. When that discretionary language exists and is enforceable, courts often use a more deferential standard. In practical terms, that can make the appeal record even more important because later judicial review may focus on whether the administrator acted reasonably, not whether the judge would have reached the same result independently.
That is why an appeal often serves two functions at once:
- It asks the insurer or plan to reverse the denial now.
- It preserves the arguments, evidence, and procedural issues that may matter later in court.
The Department of Labor’s ERISA claims-procedure rules are built around the idea of a “full and fair review.” Claimants are generally entitled to relevant documents on request, and plans that fail to follow required procedures can face consequences in later litigation, including arguments about deemed exhaustion and, in some courts, a less deferential review posture. See the Department of Labor’s guidance on full and fair review and relevant documents and the claims-procedure regulation at 29 C.F.R. § 2560.503-1.
Here’s what this often means in real life: if the standard-of-review fight is coming, the administrative appeal is where many of the future arguments get built.
Step 1: Read The Plan Like The Standard Of Review Depends On It
In many ERISA cases, it does.
The first document to study is not the denial letter. It is the plan itself and any governing summary plan description, certificate, policy, or delegated claims-administration language that may affect discretion. Under Firestone, the central question is often whether the plan expressly gives discretionary authority to the administrator or fiduciary. If it does not, de novo review may be the default. If it does, the case may move into abuse-of-discretion territory, depending on the jurisdiction and other issues.
This is one reason appeal strategy and plan interpretation are so closely connected. Language about who decides eligibility, who interprets terms, and whether a third-party administrator received delegated authority can shape the whole case from the start.
When reading the plan, people in similar situations often focus on:
- language granting discretion
- definitions of disability, medical necessity, own occupation, any occupation, or experimental treatment
- proof requirements
- deadlines and appeal rights
- limits on evidence
- authority delegated from the plan sponsor to an insurer or claims administrator
If you want a deeper look at the bigger picture, this discussion of why plan wording can steer the court’s review is a useful companion.
Step 2: Assume The Administrative Record May Be The Main Record Forever
One of the defining features of ERISA litigation is that many cases are decided largely on the administrative record created during the claim and appeal process. That makes the appeal very different from an ordinary complaint-driven lawsuit where discovery comes later and fills in the gaps.
If a treating doctor’s opinion, vocational evidence, job-demand analysis, pharmacy history, imaging, test results, witness statements, or rebuttal report never made it into the claim file, there is a real possibility it will be far harder to use later.
That is especially important when a deferential standard may apply. If a court is later asking whether the administrator had a reasonable basis, the evidence that was actually before the administrator becomes critical. Even in de novo review cases, courts often place substantial weight on the developed administrative record.
For many claimants, this is the point where an attorney’s documented experience in highly-similar matters becomes especially relevant. An attorney may help determine what evidence belongs in the file before the appeal closes, rather than trying to fix an incomplete record after litigation begins.
Step 3: Request The Entire Claim File And All Relevant Materials Early
ERISA’s claims-procedure rules generally give claimants access, upon request, to relevant documents, records, and other information relating to the claim. Department of Labor guidance has taken an expansive view of “relevant,” including materials generated or considered during the determination process, not only the documents expressly relied on in the denial. See the DOL’s 2021 information letter and the regulation itself at 29 C.F.R. § 2560.503-1.
A thorough request often seeks:
- the full claim file
- internal notes and claim-log entries
- medical-review reports
- vocational reviews
- surveillance materials, if any
- policy provisions relied upon
- internal guidelines or manuals, where relevant
- communications with reviewing vendors
- recordings or transcripts of claim-related calls, where applicable
- any new evidence or rationale introduced during appeal
For disability claims, current regulations provide additional protections. The Department of Labor announced rules requiring a claimant’s right to review and respond to new information or rationales developed during the appeal, along with protections aimed at the independence and impartiality of decision-makers. Those protections generally apply to disability claims submitted on or after January 1, 2018. See the DOL release on the disability-claims rule changes and the text of 29 C.F.R. § 2560.503-1.
This matters for the standard-of-review fight because procedural defects can become more than technicalities. They can affect exhaustion arguments, record completeness, and the degree of deference a court may be willing to apply.
Step 4: Build Evidence For Both Merits And Standard Of Review
A strong ERISA appeal often does two jobs at the same time.
Build The Merits Record
This includes the traditional material:
- updated treating-provider opinions
- narrative letters that apply symptoms to plan definitions
- objective testing where available
- functional-capacity evidence
- neuropsychological testing when cognitive issues are central
- pharmacy and treatment compliance records
- job descriptions and occupational analyses
- witness statements from supervisors, family members, or coworkers
- rebuttals to paper reviews that misunderstood the record
The key is not just volume. It is fit. The evidence often works best when it directly answers the actual language of the plan and the stated reasons in the denial letter.
Build The Review-Standard Record
At the same time, the appeal can document issues such as:
- missing or unclear discretionary language
- procedural defects
- failure to consider material evidence
- selective reading of the file
- conflicts of interest
- reliance on new rationales without a fair chance to respond
- use of reviewers whose analysis appears incomplete or one-sided
In Metropolitan Life v. Glenn, the Supreme Court recognized that when the entity deciding claims also pays benefits, that structural conflict of interest is a factor in judicial review. The weight of that factor depends on context. In other words, conflict alone does not automatically decide the case, but evidence showing that the conflict may have influenced the process can become relevant later.
This is where a careful appeal can do important work. If the insurer ignored favorable treating evidence, failed to reconcile its position with a Social Security award it encouraged the claimant to seek, or withheld important information from consultants, those details may matter both on the merits and in how a court views the administrator’s process.
Step 5: Answer The Denial Letter Point By Point
Many appeals are weaker than they look because they say, in effect, “the decision was wrong,” without squarely addressing why the denial letter says the claim was denied.
A better approach is often a point-by-point structure:
- Quote or summarize each stated reason for denial.
- Identify the plan language tied to that reason.
- Respond with record citations and supporting evidence.
- Explain where the denial misread, ignored, or overstated the evidence.
- Preserve any procedural objection tied to that issue.
For example, if a denial says there is “insufficient objective evidence,” the appeal might address:
- whether the condition is one that is not fully captured by lab tests
- what objective evidence does exist
- how the plan defines proof
- whether the insurer improperly demanded evidence beyond the plan language
- whether the reviewing doctor meaningfully engaged with treating records
The same logic applies to medical-necessity denials, own-occupation disputes, mental-health limitations, and preexisting-condition exclusions.
When the appeal is built this way, it becomes easier later to show not only that the record supported benefits, but also that the administrator may have failed to conduct the kind of fair review ERISA contemplates.
Step 6: Watch Closely For Procedural Errors
Procedural errors can be easy to overlook while everyone is focused on the medical evidence. But they can matter a great deal.
The Department of Labor’s rules require plans to provide a reasonable claims procedure and a full and fair review. The DOL’s FAQ explains that if a plan fails to establish or follow claims procedures consistent with the regulation, the claimant may be deemed to have exhausted administrative remedies and may pursue available remedies in court. See the DOL’s claims-procedure FAQ.
Examples of issues that may become important include:
- late decisions
- incomplete denial notices
- failure to identify the plan provisions relied on
- failure to describe additional information needed to perfect the claim
- failure to provide relevant documents
- use of the same reviewer or insufficiently independent reviewers on appeal
- new evidence or rationales disclosed too late for a meaningful response
- failure to consider submissions sent during the appeal window
In some courts, serious procedural noncompliance has also influenced the standard-of-review analysis. For example, the Second Circuit’s approach in Halo v. Yale Health Plan became well known for rejecting a forgiving “substantial compliance” concept in that context. Other circuits have taken different paths, and ERISA doctrine can vary significantly by jurisdiction. That variation is one more reason many claimants look for counsel with demonstrable experience in the relevant circuit and claim type.
Step 7: Know That Circuits Can Disagree On Important Review Questions
The broad Firestone rule is settled, but some ERISA review issues still vary by jurisdiction.
A notable example comes from the Fifth Circuit’s en banc decision in Ariana M. v. Humana Health Plan of Texas. The court moved away from a prior rule that had treated some factual determinations differently and reaffirmed de novo review as the default where the plan does not validly confer discretion. The opinion also discussed how other circuits had read Firestone broadly.
Here’s what this often means: even when the headline rule sounds simple, the actual standard-of-review fight may involve circuit law on discretion clauses, procedural violations, scope of the record, conflict evidence, and how aggressively courts police claims-procedure failures.
That makes the appeal phase even more strategic. The record may later be read through the law of a specific circuit, not just general ERISA principles.
Step 8: Treat Medical, Vocational, And Plan-Language Evidence As A Single Story
One common mistake is treating the case as purely medical. Another is treating it as purely legal. Stronger appeals usually connect all three dimensions:
- Medical evidence: what the diagnosis, symptoms, restrictions, and treatment history show
- Vocational evidence: what the claimant’s actual job or occupational duties required
- Plan language: what the policy actually says counts as disability, medical necessity, proof, or exclusion
A claimant may have extensive medical records and still lose if the appeal never ties those records to the operative plan language. The reverse is also true: a sharp legal argument can fall flat if the file lacks persuasive proof on function, capacity, or work demands.
If the standard of review may become deferential, this integrated approach becomes even more important. Courts often look for a grounded explanation of why the administrator’s reading of the record and the plan was unreasonable, incomplete, or procedurally unsound.
Step 9: Use The Appeal To Make Future Litigation Simpler, Not Harder
The best ERISA appeals often make later litigation feel more focused.
That may include:
- creating a clear timeline
- identifying every issue preserved for review
- organizing exhibits with record citations
- spelling out objections to missing materials
- addressing conflicts and procedural irregularities in writing
- requesting written confirmation that all submitted materials were considered
- clarifying what relief is sought and under which plan terms
This kind of structure can help a court see the case more clearly later. It can also reduce the chance that important arguments get lost in an oversized but poorly organized file.
In general terms, a good appeal brief often reads like a future merits brief drafted early enough to influence the decision-maker now.
Step 10: Consider Why Attorney Fit Matters So Much In ERISA Appeals
ERISA appeals are unusually technical. A lawyer can be excellent in one practice area and still have limited experience with ERISA standards of review, administrative-record strategy, disability-claims regulations, or circuit-specific procedural doctrine.
That is why many people look beyond general marketing language and focus on documented experience, relevant experience, and demonstrable experience in highly-similar matters. In an ERISA case, attorney fit often has less to do with broad reputation and more to do with whether the lawyer understands how plan language, record development, procedure, and standard of review interact.
This is also where a search process based on objective criteria and court-record evidence can be more useful than generic attorney advertising. If a case may hinge on issues like discretion clauses, claim-file development, conflict arguments, or the consequences of procedural noncompliance, it can help to find counsel whose background reflects those exact issues.
A Short Summary
Building an ERISA appeal with the standard-of-review fight in mind means thinking a step ahead. The appeal is not only a request for reversal. It is the place where plan language gets tested, evidence gets preserved, procedural defects get documented, and the future court record often takes shape.
If de novo review is possible, the appeal can help frame the merits cleanly. If abuse-of-discretion review may apply, the appeal can help show why the administrator’s process and reasoning do not deserve confidence. Either way, the case is often stronger when the record is built deliberately, with both the present denial and the later review standard in mind.
