Biestek v. Berryhill

Updated Sep 18, 2026

In brief

The Court said a vocational expert can still provide enough evidence about available jobs even when the expert does not turn over private survey data.

Where it stands
Decided

Decided 6-3 · April 1, 2019 · Opinion by Justice Kagan

What it’s about
This case was about a Social Security disability benefits hearing in which an administrative law judge relied on a vocational expert’s testimony about jobs the claimant could still do, even though the expert refused to turn over the survey data behind her job-number estimates.
Who it affects
The decision means an expert's refusal to produce supporting job-survey data does not automatically disqualify the testimony. Courts must instead assess whether the evidence is reliable enough in the circumstances of each case.

What it's about

The Supreme Court decided that such testimony is not automatically disqualified and can still count as substantial evidence, depending on the circumstances of the case.

The case concerns how the Social Security Administration decides whether a person with disabilities can adjust to other available work.

Question presented

Whether a vocational expert's testimony can constitute substantial evidence of "other work," 20 C.F.R. § 404.1520(a)(4)(v), available to an applicant for social security benefits on the basis of a disability, when the expert fails upon the applicant's request to provide the underlying data on which that testimony is premised.

What the Court decided

Holding

A vocational expert’s refusal to provide private market-survey data upon the applicant’s request does not categorically preclude the testimony from counting as “substantial evidence.” Substantial evidence is “more than a mere scintilla,” and means only “such relevant evidence as a reasonable mind might accept as adequate to support a conclusion.” Consolidated Edison Co. v. NLRB , 305 U. S. 197, 229. Biestek proposes a categorical rule that the testimony of a vocational expert who refuses a request for supporting data about job availability can never clear that bar. 880 F. 3d 778, affirmed.
