Horn & Kelley, national leaders in Social Security Disability law, won another United States District Court case Aug. 28, 2013, in Koppers v. Colvin, 12 C 3993. The case was reversed and remanded to the Social Security Administration for another hearing. The Administrative Law Judge’s improper rejection of several pieces of evidence favorable to Plaintiff based on the Administrative Law Judge’s illogical or erroneous statements, and the failure to address other favorable evidence, fatally undermined the Administrative Law Judge’s credibility analysis in her decision against Plaintiff. The Administrative Law Judge erroneously failed to explain adequately her reasoning for nor giving controlling or great weight to the opinion of Plaintiff’s treating physician. In determining Plaintiff’s residual functional capacity, the Administrative Law Judge improperly played doctor by using her own lay opinions to fill evidentiary gaps in the record.
