This is an action pursuant to 42 U.S.C. Â§ 405(g) to review a denial of disability benefits under Title II of the Social Security Act, 42 U.S.C. Â§ 416(i), 423 (1976). By letter opinion, the district court granted summary judgment affirming the determination of the Secretary of Health and Human Services (Secretary) that Dolores Wallace was not disabled. The district court concluded that the factual findings made by the Administrative Law Judge (ALJ) were supported by substantial evidence, and this appeal followed pursuant to 28 U.S.C. Â§ 1291. For the reasons stated, we will vacate the district court judgment and remand for further proceedings.
