In order to establish initial and continued entitlement to disability benefits under the Social Security Act (Act), a worker must demonstrate that, inter alia, he is unable "to engage in any substantial gainful activity by reason of any medically determinable physical or mental impairment . . . ." The worker bears the continuing burden of showing, by means of "medically acceptable . . . techniques" that his impairment is of such severity that he cannot perform his previous work or any other kind of gainful work. A state agency makes the continuing assessment of the workers eligibility for benefits, obtaining information from the worker and his sources of medical treatment. The agency may arrange for an independent medical examination to resolve conflicting information. If the agencys tentative assessment of the beneficiarys condition differs from his own, the beneficiary is informed that his benefits may be terminated, is provided a summary of the evidence, and afforded an opportunity to review the agencys evidence. The state agency then makes a final determination, which is reviewed by the Social Security Administration (SSA). If the SSA accepts the agency determination it gives written notification to the beneficiary of the reasons for the decision and of his right to de novo state agency reconsideration. Upon acceptance by the SSA, benefits are terminated effective two months after the month in which recovery is found to have occurred. If, after reconsideration by the state agency and SSA review, the decision remains adverse to the recipient, he is notified of his right to an evidentiary hearing before an SSA administrative law judge. If an adverse decision results, the recipient may request discretionary review by the SSA Appeals Council, and finally may obtain judicial review. If it is determined after benefits are terminated that the claimants disability extended beyond the date of cessation initially established, he is entitled to retroactive payments. Retroactive adjustments are also made for overpayments. A few years after respondent was first awarded disability benefits he received and completed a questionnaire [424 U.S. 319, 320] from the monitoring state agency. After considering the information contained therein and obtaining reports from his doctor and an independent medical consultant, the agency wrote respondent that it had tentatively determined that his disability had ceased in May 1972 and advised him that he might request a reasonable time to furnish additional information. In a reply letter respondent disputed one characterization of his medical condition and indicated that the agency had enough evidence to establish his disability. The agency then made its final determination reaffirming its tentative decision. This determination was accepted by the SSA, which notified respondent in July that his benefits would end after that month and that he had a right to state agency reconsideration within six months. Instead of requesting such reconsideration respondent brought this action challenging the constitutionality of the procedures for terminating disability benefits and seeking reinstatement of benefits pending a hearing. The District Court, relying in part on Goldberg v. Kelly, 397 U.S. 254, held that the termination procedures violated procedural due process and concluded that prior to termination of benefits respondent was entitled to an evidentiary hearing of the type provided welfare beneficiaries under Title IV of the Act. The Court of Appeals affirmed. Petitioner contends, inter alia, that the District Court is barred from considering respondents action by Weinberger v. Salfi, 422 U.S. 749, which held that district courts are precluded from exercising jurisdiction over an action seeking a review of a decision of the Secretary of Health, Education, and Welfare regardi
