RUBIN, Circuit Judge:
Contending that he was unable to fulfill the physical demands of his job, Wilburn C. Anderson sought Social Security disability benefits. He appeals from a decision of the district court affirming a Social Security Appeals Council denial of those benefits. We find the decision of the Administrative Law Judge, adopted by the Secretary of Health and Human Services, not to be supported by substantial evidence. Therefore, we reverse that decision and remand for further proceedings.
Mr. Anderson has spent his thirty working years employed as a glazier. He is 51 years old and possesses only a third grade education. He cannot read and is able to write only his name. He last met the requirements of insured status in December 1977.
As a glazier, Mr. Anderson, according to his disability claim, was required to use electric drills and to lift loads sometimes as heavy as 400 pounds. His work involved
He filed his application for disability insurance benefits in 1977. When the claim was denied, Mr. Anderson requested a hearing. The ALJ, after conducting a hearing, found that the claimant "retains sufficient residual functional capacity for the performance of his usual work" and was "capable of engaging in substantial gainful activity during the claimed period of disability in his usual occupation." He, therefore, concluded that Mr. Anderson was not entitled to benefits. The ALJ's decision was upheld by the Social Security Appeals Council. See 42 U.S.C. § 405(b); 20 C.F.R. §§ 404.940 & 404.946. Its decision is the Secretary's final determination. Pursuant to 42 U.S.C. § 405(g), Mr. Anderson appealed that denial to the district court. Finding substantial evidence to support the conclusion reached by the Appeals Council, the district court granted summary judgment in favor of the Secretary. This appeal followed.
The Social Security Act imparts substantial discretion to the Secretary. It does not give us the power to review findings of fact, even for clear error, and, of course, does not permit us to substitute our judgment for his. We are straitly confined by 42 U.S.C. § 405(g) to determining, upon careful review of the entire record, whether it contains substantial evidence to support the Secretary's findings. See Richardson v. Perales, 402 U.S. 389, 401, 91 S.Ct. 1420, 1427, 28 L.Ed.2d 842, 852 (1971); Grant v. Richardson, 445 F.2d 656 (5th Cir. 1971); Ratliff v. Richardson, 445 F.2d 440 (5th Cir. 1971). This does not mean we affirm on gossamer. Substantial evidence is such relevant evidence as a reasonable mind might accept as adequate to support a conclusion.
In order to recover disability benefits, the claimant bears the burden of proving that he is disabled within the meaning of the Social Security Act. Johnson v. Harris, 612 F.2d 993, 997 (5th Cir. 1980); Fortenberry v. Harris, 612 F.2d 947, 949 (5th Cir. 1980); Demandre v. Califano, 591 F.2d 1088, 1090 (5th Cir. 1979). Disability, as defined by the Act, is the inability "to engage in any substantial gainful activity by reason of any medically determinable physical or mental impairment which can be expected to result in death or which has lasted or can be expected to last for a continuous period of not less than twelve months." 42 U.S.C. § 423(d)(1)(A). An individual fulfills this burden, and is considered disabled,
42 U.S.C. § 423(d)(2)(A).
The existence of disability is often analyzed by means of a sequential evaluation. 20 C.F.R. § 404.1503. After the Secretary determines that the claimant is not then engaged in substantial gainful activity, he must ascertain whether the claimant suffers an impairment that significantly limits the claimant's physical or mental capacity to perform basic work-related activities. If no such impairment exists, a finding of disability is precluded. If, on the other hand, a severe impairment exists, then the Secretary must examine the claimant's residual functional capacity and the demands of the kind of work he can do, based on past work experience. If the claimant is unable to perform the functions required by his past work, the Secretary must determine whether, considering the claimant's age, education and work experience, he is able to meet the demands of
The claimant bears the burden of proving a severe impairment that makes him unable to pursue his customary employment. Once he does so, however, the burden shifts to the Secretary to prove that the claimant can perform another type of substantial gainful employment. Wilkinson v. Schweiker, 640 F.2d 743, 744 (5th Cir. 1981); Western v. Harris, 633 F.2d 1204, 1207 (5th Cir. 1981); Fortenberry v. Harris, 612 F.2d 947, 949 (5th Cir. 1980).
The ALJ concluded that, based on the claimant's own testimony, expert opinion, and other relevant evidence, Mr. Anderson had failed to prove the existence of any severe impairments that precluded him from engaging in his usual occupation of glazier. Based on a review of the entire record, we are unable to conclude that the Secretary's conclusion is supported by substantial evidence.
The ALJ made no findings concerning the nature of Mr. Anderson's duties in his work as a glazier. His opinion refers only to the fact that glazier's work is "medium work ... according to the Dictionary of Occupational Titles, Third Edition." While one doctor, apparently erroneously, referred to Mr. Anderson's work as supervisory, the record contains no evidence to contradict the reports of other physicians, based on Anderson's statements, that his work required him to lift heavy weights, to stand long periods, and to bend repeatedly. No inquiry into Mr. Anderson's exact duties was made at the hearing. The record does support the inference that, for a period after his injury, Mr. Anderson's sons worked as glaziers, sharing earnings with him, but that they were in effect doing all the physical work. While Mr. Anderson was represented by counsel at the hearing (other than the counsel who now represents him), his lawyer simply delegated examination of Mr. Anderson to the ALJ. The record does not enable us to determine affirmatively the physical requirements of glazier's work, but it certainly does not contain substantial evidence to negate the contention, inferentially supported by other evidence, that the work entails substantial exertion.
In addition, there is uncontradicted evidence (consisting in part of the ALJ's observations at the hearing) that Mr. Anderson's hands were then too palsied to permit him to cut glass. The record does not contain any findings concerning whether this was an impairment and, if so, when it commenced. There is much medical evidence that Mr. Anderson could be retrained to perform light physical labor or sedentary work, but the ALJ did not deny benefits based on Mr. Anderson's ability to perform other jobs, but solely on the basis that he could work as a glazier.
The ALJ, the Appeals Council, and the district court considered the reports of eleven physicians and other experts. The expert opinions varied materially. Were we to disregard their chronology, assign equal weight to each, and examine only those supporting the Secretary's determination, we might find substantial evidence in those thus winnowed out. When, however, the experts' opinions are examined chronologically, their support for the Secretary's determination is weakened. Two physicians examined Mr. Anderson after he was injured in November 1973 and, despite his consistent complaints of pain, they reported no major physical impairments. The next physician to examine Mr. Anderson, Dr. Baston, reported that the claimant experienced continued pain. Dr. Baston diagnosed the problem as a severe back strain. He prognosticated that Mr. Anderson would be able to do full-time work not requiring heavy lifting.
Although Mr. Anderson continued to report pain throughout 1974 and 1975, three physicians who examined him during this period reported nothing more severe than a lumbosacral sprain.
Dr. Selby, in May 1975,
We conclude, therefore, that the medical evidence presented, rather than substantially supporting the Secretary's conclusion, inferentially supports the conclusion that Anderson's impairment became progressively worse and that he was unable to work as a glazier on or before December 1977. Compare Demandre v. Califano, 591 F.2d 1088, 1090 (5th Cir. 1979) ("The medical evidence generally supports a finding that claimant's condition deteriorated after expiration of his insured status. There is substantial evidence in the record to support ... the Secretary's decision denying plaintiff's claim.") (emphasis in original). We do not preclude the possibility that the initial conclusion could properly be again reached on remand, after a full investigation of the actual demands of Mr. Anderson's work as a glazier, and a further review of the evidence, together with any new or additional evidence that may be appropriate. We simply do not think the present record adequate to support the determination that Mr. Anderson can return to his former work.
If he is not able to do so, the burden shifts to the Secretary to prove that, considering Mr. Anderson's age, experience and limited education, there is another type of substantial gainful employment that he can perform. Because of the sequential method of analysis utilized, however, no evidence was presented concerning the existence of alternative employment opportunities
REVERSED AND REMANDED.
