Whether the Social Security Act permits the Secretary to use medical-vocational guidelines, rather than vocational-expert testimony in every case, to determine whether work exists in the national economy for a disability claimant.
Holding
Yes. The Secretary may rely on valid medical-vocational guidelines in appropriate cases to determine whether jobs exist in significant numbers in the national economy for a claimant with specified vocational and physical characteristics.
Reasoning
The Social Security Act gives the Secretary broad authority to adopt reasonable rules governing the nature and extent of evidence in disability cases. Because Congress expressly entrusted implementation of the disability program to the Secretary through regulation, the Court’s review asks whether the regulations exceed statutory authority or are arbitrary and capricious. The grids met neither defect.
A disability determination has two relevant components once a claimant cannot perform past work. First, the agency must make individualized factual findings about the claimant’s residual physical capacity, age, education, and work experience. Second, it must determine the generally applicable question whether jobs exist in the national economy for someone with those characteristics.
The first inquiry must be resolved from evidence developed at the claimant’s hearing because it turns on the claimant’s own limitations and history. The regulations also permit a claimant to show that the grids do not accurately describe her particular limitations, including limitations not captured by the exertional categories.
The second inquiry—the types and numbers of jobs available in the national economy—is not unique to one claimant. The agency may resolve that general factual issue through rulemaking just as fairly as it could through repetitive vocational-expert testimony at individual hearings. Rulemaking avoids continual relitigation of the same labor-market facts.
The grids also advance legitimate administrative goals. They promote uniform treatment of similarly situated claimants and conserve the resources of an agency handling an enormous volume of disability claims. On the record before the Court, their use was neither inconsistent with the statute nor arbitrary and capricious.
