Barnhart v. Thomas
The Supreme Court ruled that the Social Security Administration does not have to check whether a disability applicant's old job still exists in the economy before deciding she is not disabled because she can still do that old job.
The decision upholds the agency's long-standing five-step process for evaluating disability claims and means the government can rely on a person's ability to do her previous work as a stand-in for whether she can work at all, without a separate check on job availability.
“We need not decide today whether § 423(d)(2)(A) compels the interpretation given it by the SSA.”
The Court explains it is only upholding the agency's reading as reasonable, not as the only possible one.
How it got here: An administrative judge and the district court sided with the agency; the Third Circuit, sitting en banc, reversed, and the Supreme Court agreed to review that ruling.
The Case in Depth
What happened
Pauline Thomas worked as an elevator operator for six years until her job was eliminated in 1995. She later applied for Social Security disability benefits, claiming she was disabled by heart disease and spine problems. An administrative judge found she still had the physical capacity to do her old elevator-operator job and denied benefits, even though that kind of job had become rare in the modern economy.
The question before the Court
If someone can't do her old job anymore, but that job barely exists anymore, can Social Security still deny her disability benefits based on that old job?
Why it matters
Millions of people who apply for Social Security disability benefits each year will continue to be screened under the agency's existing rules, which can deny benefits to someone who is physically able to do a past job even if that specific job has vanished from the economy. This keeps the disability process faster and more predictable, though it means some applicants in shrinking industries could be denied benefits despite limited real job prospects.
What changes now
The Third Circuit's ruling in favor of the claimant is reversed, meaning the Social Security Administration's original denial of benefits stands under its existing five-step evaluation process. Going forward, the agency can continue denying disability claims at step four based solely on a claimant's ability to do her past relevant work, without inquiring whether that specific job still exists in meaningful numbers in the economy. This is a final decision on the merits, not a temporary order.
What this does not decide
The Court did not decide that the statute requires the agency's reading -- only that the statute does not clearly forbid it and that the agency's approach is a reasonable one. The ruling addresses only the definition used at step four of the process, not the separate step-five inquiry into other available jobs.
How the Court got there
The legal reasoning, step by step
- The Court applied Chevron deference, the rule that courts must defer to a federal agency's reasonable reading of an ambiguous statute it administers, and asked whether the disability law clearly resolved the question or left room for the agency's approach.
- The statute denies benefits unless a person's impairment stops her from doing her previous work and also stops her from doing any other kind of work that exists in significant numbers in the national economy. The question was whether the 'exists in the national economy' requirement also applies to the 'previous work' half of that test.
- The Court relied on the grammatical rule of the last antecedent, which says a qualifying phrase normally modifies only the specific term right before it, not an earlier, separately listed item. Applying that rule, the 'exists in the national economy' language modifies only 'other work,' not 'previous work.'
- The Court illustrated this with an analogy about parents forbidding a party or 'any other activity that damages the house' -- the party is banned outright, regardless of whether it actually causes damage, showing that a specific item listed before a general catch-all need not meet the catch-all's qualifying condition.
- The Court reasoned that using a person's ability to do her past work as a stand-in for her ability to do any work at all is a reasonable administrative shortcut, since in most cases someone who can still do her old job can also do other jobs, and checking job availability at this stage would slow down a very high-volume benefits system.
- Because the statute did not clearly rule out the agency's reading and that reading was reasonable, the Court held the agency's interpretation must be given effect under Chevron.
