Background

O.W. sought Supplemental Security Income, alleging that mental and physical conditions prevented him from working. An administrative law judge found several severe mental impairments but concluded that O.W. could still perform jobs identified by a vocational expert, including bench hand packager, inspector, and sub-assembler. The Appeals Council declined review.

In federal court, O.W. challenged the evaluation of his migraines, an examining psychologist’s opinion, his symptom testimony, the resulting residual functional capacity, and the vocational evidence. He also submitted SkillTRAN data showing far fewer jobs in the national economy than the vocational expert had estimated.

The Court’s Holding

The court reversed and remanded for a new administrative decision. It held that the agency could not defend the omission of migraines with a rationale the administrative law judge never gave. The record contained migraine evidence, and the decision did not explain whether or how that condition affected the severity analysis or O.W.’s work capacity.

The court also found defects in the treatment of psychologist Laura Catlin’s evaluation. The administrative law judge described mental-health care as conservative and relied heavily on generally normal observations, but much of that evidence came from the structured environment of incarceration. The record also included abnormal findings and treatment that undercut a simple characterization of the condition as mild. Those errors affected the assessment of O.W.’s limitations and required renewed consideration on remand.

Separately, the court concluded that O.W.’s competing job-number evidence was both probative and significant. SkillTRAN figures tied to the same occupational codes showed approximately 1,133, 6,952, and 12,901 jobs, while the vocational expert estimated 32,000, 101,000, and 30,000. Under Ninth Circuit authority, the agency had to address that substantial discrepancy rather than rely on the expert’s figures without resolution. The court declined to order immediate benefits because factual issues remained for the agency to decide.

Key Takeaways

  • A reviewing court evaluates the reasons actually stated by the administrative law judge; agency counsel cannot supply a missing rationale later.
  • All medically supported impairments must be considered when determining work capacity, even if an impairment is not ultimately classified as severe.
  • Normal observations made in a structured prison setting may not reliably demonstrate an ability to function in a competitive workplace.
  • SkillTRAN evidence keyed to the vocational expert’s occupational codes can create a significant job-number conflict that the agency must resolve.
  • Proof of legal error does not automatically produce an award of benefits when unresolved factual questions remain.

Why It Matters

For California disability practitioners, the ruling reinforces two practical record-building points. Challenges should connect omitted conditions to functional limitations, and competing vocational data should identify the same job codes used at the hearing and show the size of the numerical disparity.

The decision also cautions adjudicators against treating mental-health evidence from incarceration as interchangeable with performance in ordinary employment. On remand, the agency must reassess the medical and symptom evidence, formulate a supported residual functional capacity, and obtain or evaluate vocational evidence that addresses the competing job estimates.
