Sweeney v. Barnhart
Robert Sweeney, the claimant, appealed the Commissioner of Social Security's denial of disability benefits under the Social Security Act. Sweeney alleged disability due to depression, but also had a significant history of alcohol and substance abuse, which led to job termination and arrests. The Administrative Law Judge (ALJ) found that while Sweeney had severe impairments, his drug and alcohol addiction was a material contributing factor to his disability. The District Court affirmed the Commissioner's decision, agreeing that without the effects of substance abuse, Sweeney retained the capacity to perform his past relevant work, thus upholding the denial of benefits.
