In one sentence

In G.P. v. O'Malley, Judge DeMarchi reversed the benefits denial and remanded to determine onset and calculate benefits after finding errors in the administrative law judge’s analysis.

Who this affects

G.P. is affected because the denial of his Social Security benefits was reversed and the case was remanded to determine his disability onset date and calculate benefits. The Commissioner of Social Security is affected because the agency must carry out that remand.

What happened

In G.P. v. O'Malley, G.P. challenged the Social Security Administration’s denial of child disability insurance benefits and supplemental security income. The administrative law judge found that G.P. would not be disabled without alcohol and methamphetamine use and therefore denied benefits.

The parties agreed that the administrative law judge made an error by relying on medical opinions but not including all their stated limitations in G.P.’s work-capacity assessment or explaining why he left them out. The court concluded that, if those limitations were included, the record showed G.P. could not perform available work even during periods without substance use, so the substance use was not material to his disability. The court nevertheless found that the disability onset date remained unresolved.

Judge Virginia K. DeMarchi granted G.P.’s appeal, reversed the administrative law judge’s decision, and remanded the matter to determine the disability onset date and calculate benefits. The court denied the Commissioner’s request for a remand for further administrative proceedings and directed the Clerk to enter judgment and close the case.

Case
G.P. v. O'Malley · No. 5:24-cv-00088
Judge
Virginia Demarchi
Date
Mar. 28, 2025

Background

G.P. sought child disability insurance benefits under Title II of the Social Security Act and supplemental security income under Title XVI. He alleged that his disability began on March 31, 2004. The administrative law judge found severe physical and mental impairments, including seizures, heart and renal conditions attributed to methamphetamine use, several mental disorders, and alcohol and methamphetamine use disorder.

The administrative law judge determined that G.P.’s mental impairments met the regulatory criteria when substance use was included. The judge then found that, if G.P. stopped using substances, he would retain certain work-related limitations but could perform jobs such as hospital cleaner, photocopying machine operator, and advertising material distributor. The judge therefore concluded that substance use was a contributing factor material to the disability determination and denied benefits.

Error in the Administrative Law Judge’s Decision

The parties agreed that the administrative law judge committed reversible error by adopting a residual functional capacity—the most a person can still do in a work setting—that did not fully account for limitations in the opinions of Dr. Mary Ann Vigilanti and Dr. Nadine J. Genece. The administrative law judge described both opinions as persuasive and relied on them, but did not include limitations concerning workplace stress, reliable attendance, and other moderate limitations. The judge also did not explain why those limitations were omitted.

The court noted that the vocational expert testified that an individual who was absent twice per month or who could not interact with the general public would be unable to perform any work in the national economy. The court found that the administrative law judge’s allowance of one absence per month did not fully capture the limitations identified by the two doctors.

Substance-Use Materiality

Social Security regulations require determining whether a claimant would still be disabled if the claimant stopped using drugs or alcohol. The court rejected the Commissioner’s argument that improvement during sobriety, by itself, could establish that G.P.’s substance use was material. The relevant question was whether G.P.’s functioning during sobriety improved enough that he would not be disabled.

The record reflected, and the parties appeared to agree, that G.P. did not use drugs or alcohol for approximately two years from 2019 to 2021. The court concluded that, if the limitations identified by Drs. Vigilanti and Genece were fully credited and included in the work-capacity assessment, G.P. would have been unable to perform any work even without substance use. The court therefore concluded that substance use was not material under the applicable regulations and found that no further administrative proceedings were necessary to resolve that issue.

Onset Date and Disposition

G.P. alleged a March 31, 2004 onset date, but the administrative law judge found no medical signs or laboratory findings supporting an impairment before the first treatment record in October 2011. The administrative law judge did not determine an alternative onset date, and the parties did not address that issue in their briefs. The court therefore held that the onset date had to be determined in the first instance on remand.

Judge Virginia K. DeMarchi granted G.P.’s appeal, reversed the administrative law judge’s decision, and remanded the matter for determination of the disability onset date and calculation of benefits. The court denied the Commissioner’s request for a remand for further administrative proceedings on the issue of whether substance use was material. The Clerk was directed to enter judgment and close the file.
