Corralejo v. Bisignano: Ninth Circuit Reaffirms Strict Appeals Standards
- Jan 29
- 2 min read
This Ninth Circuit memorandum opinion doesn’t break new legal ground—but it reinforces several recurring themes in social security appeals, especially when records are thin and arguments are underdeveloped.
Key Takeaways
Appeals fail when records lack support and arguments are weak.
Claimants must clearly articulate legal theories at every step.
The Ninth Circuit will affirm favorable agency decisions when plaintiffs don’t carry their burden.
Step Two: “Severe” Means Functional Limitations, Not Just Diagnoses
What Happened
The Administrative Law Judge (ALJ) found only one severe impairment: diabetes mellitus.
All other alleged impairments were excluded at step two.
Ninth Circuit’s Reasoning
The court emphasized that only functionally supported impairments matter at step two.
Diagnoses mentioned in the record aren’t “severe” unless they are shown to affect functional ability.
Why This Matters
Step‑two errors are harmless unless they affect the RFC or the ultimate decision.
The claimant herself testified that diabetes was her reason for stopping work and that nothing else prevented her from working — and that fact carried weight.
Objective Evidence Still Matters (Even in 2025)
The Knee Pain Issue
The claimant said she had knee pain from a “bone island.”
The court noted a lack of objective medical evidence of any functional limitation.
Legal Principle
Under Smolen, subjective complaints alone don’t establish a medically determinable impairment.
Objective medical support is a must for alleged physical limitations.
Practical Lesson
Merely feeling pain isn’t enough — the record must show an impairment that reasonably could cause functional limitations.
Step Three: Boilerplate Language Is Fine When the Claimant Offers Nothing
The Claimant’s Argument
The claimant argued the ALJ’s step‑three analysis was “boilerplate.”
Court’s Response
That argument failed because the claimant never identified a specific listing she believed was met or equaled.
Important Rule
If a claimant does not explain how an impairment meets a listing, the ALJ’s brief explanation is acceptable.
A late argument in a reply brief about an “independent duty” to identify listings was waived.
Practice Tip
Be explicit, early, and specific when asserting that a listing is met or equaled.
RFC: Consultative Exams Still Carry Real Weight
How the ALJ Built the RFC
The RFC supported medium work with some non‑exertional limits.
It relied heavily on a consultative examiner (CE).
What Went Wrong
The claimant did not challenge the CE’s reliability in her opening brief.
The Ninth Circuit treated that omission as forfeiture.
Lesson for Practitioners
If you plan to attack a CE’s opinion, do it clearly and early — not in a later reply brief.
Bottom Line: Why Corralejo Matters
This case isn’t groundbreaking, but it is instructive about how the Ninth Circuit approaches appeals:
The Court Is Comfortable Affirming When:
Claimant testimony narrows the theory of disability
Alleged impairments lack objective support
Step‑three arguments are undeveloped
RFC challenges are raised late or inconsistently
Practical Advice for Litigators
To succeed on appeal in the Ninth Circuit:
Build a strong, detailed agency record at every step.
Be precise in your arguments, especially at step two, step three, and in RFC challenges.
Address consultative exam issues head‑on in the opening brief.
