delivered the opinion of the Court:

This case involves the validity of the Government’s revocation of security clearance granted to petitioner, an aeronautical engineer employed by a private manufacturer which, produced goods for the armed services. Petitioner was discharged from his employment solely as a consequence of the revocation because his access to classified information was required by the nature of his job. After his discharge, petitioner was unable to secure *476employment as an aeronautical engineer and for all practical. purposes that field of endeavor is now closed to him.

Petitioner was vice president and general manager of Engineering and Research Corporation (ERCO), a business devoted primarily to developing and manufacturing various mechanical and electronic products. He began this employment in 1937 soon after his graduation from the Guggenheim School of Aeronautics and, except for a brief leave of absence, he stayed with the firm until his discharge in 1953. He was first employed as a junior engineer and draftsman. Because of the excellence of his work he eventually became a chief executive officer of the firm. During his career with ERCO, he was credited with the expedited development of a complicated electronic flight simulator and with the design of a rocket launcher, both of which were produced by ERCO and long used- by the Navy.

During the post-World War II period, petitioner was given security clearances on three occasions.1 These were required by the nature of the projects undertaken by ERCO for the various armed services.2 On November 21, *4771951, however, the Army-Navy-Air Force Personnel Security Board (PSB) advised ERCO that the company’s clearances fpr access to classified information were in jeopardy because of a tentative decision to deny petitioner access to classified Department of Defense information and to revoke his clearance for security reasons.3 ERCO was invited to respond to this notification. The corporation, through its president, informed PSB that petitioner had taken an extended furlough due to the Board’s action. The ERCO executive also stated that in his opinion petitioner was a loyal and discreet United States citizen and that his absence denied to the firm the- services of an outstanding engineer and administrative executive. On December 11, 1951, petitioner was informed by the Board that it had “decided that , access by you to contract work and information [at ERCO] ... would be inimical to *478the best interests of the United States.” Accordingly, the PSB revoked ■ petitioner’s clearances. He was informed that he could seek a héaring before the Industrial Employment Review Board (IERB), and he took this course.4 Prior to the hearing, petitioner received a letter informing him that the PSB action was based on information indicating that between 1943 and 1947 he had associated with Communists, visited officials of the Russian Embassy, and attended a dinner given by an allegedly Communist Front organization.5

On January 23,1952, petitioner, with counsel, appeared before the IERB. He was questioned in detail concerning his background and the information disclosed in the IERB letter. In response to numerous, and searching questions he explained in substance that specific “suspect” persons with whom he was said to have associated were actually friends of his ex-wife. He explained in some detail that during his first marriage, which lasted from *4791942 through 1947, his then wife held views with which he did not concur and was friendly with associates and other persons with whom he had little in common. He stated that these basic disagreements were the prime reasons that the marriage ended in failure; He attributed to his then wife his attendance at the dinner, his membership in a bookshop association which purportedly was a “front” organization, and the presence in his home of “Communist” publications. He denied categorically that he had ever been a “Communist” and he spoke at length about his dislike for “a theory of Government which has for its object the common ownership of property.” Lastly, petitioner explained that his visits to persons in various foreign embassies (including the Russian Embassy) were made in connection with his attempts to sell ERCO’s products to their Governments. Petitioner’s witnesses, who included top-level- executives of ERCO and a number of military officers who had worked with petitioner in the past, corroborated many of petitioner’s statements and testified in substance that he was a loyal and discreet citizen. These top-level executives of ERCO, whose right to clearance was never challenged, corroborated petitioner’s testimony concerning his reasons for visiting the Russian Embassy.

The Government presented no witnesses. It was obvious, however, from the questions posed to petitioner and to his witnesses, that the Board relied on confidential reports which were never made available to petitioner. These reports apparently were compilations of statements taken from various persons contacted by an investigatory agency. Petitioner had no opportunity to confront and question persons whose statements reflected adversely on him or to confront the government investigators who took their statements. Moreover, it seemed- evident that the Board itself had never questioned the investigators and *480had never seen those persons whose statements were the subject of their reports.

On January 29, 1952, the IERB, on the basis of the testimony given at the hearing and the confidential reports, reversed the action of the PSB' and informed petitioner and ERGO that petitioner was authorized to work on Secret contract work.

On March 27, 1953, the Sécretary of Defense abolished the PSB and IERB and directed the Secretaries of the three armed services to establish regional Industrial Personnel Security Boards to coordinate the industrial security program.6 The Secretaries were also instructed to establish uniform standards, criteria, and procedures.7 *481Cases pending before the PSB and IERB were referred to these new Boards.8 During the interim period between the abolishment of the old program and the implementation of the new one, the Secretaries considered themselves charged with administering clearance activities under previously stated criteria.9

On April 17, 1953, respondent Anderson, the Secretary of the Navy, wrote ERCO that he had reviewed petitioner’s case and had concluded that petitioner’s “continued access to Navy classified security information [was] inconsistent with the best interests of National Security.” No hearing preceded this notification. He requested ERCO to exclude petitioner “from any part of your plants, factories or sites at which classified Navy projects are being carried out and to bar him access to all Navy classified information.” He also advised the corporation that petitioner’s case was being referred to the Secretary of Defense with the'recommendation that the IERB’s decision of January 29, 1952, be overruled. ERCO had no choice but to comply with the request.10 *482This led to petitioner’s discharge.11 . ERCO informed the. Navy of what had occurred and requested an opportunity to discuss the matter in view of pétitioner’s importance to the firm.12 The Navy replied that “ [a] s far as the Navy, *483Department is concerned, any further discussion on this problem at this time will serve no useful purpose.”

Petitioner asked for reconsideration of the decision. On October 13, 1953, the Navy wrote to him stating that it had requested the Eastern Industrial Personnel Security Board (EIPSB) to accept jurisdiction and to arrive at a final determination concerning petitioner’s status.13 Var*484ious letters were subsequently exchanged between petitioner’s counsel and the EIPSB. These resulted finally in generalized charges, quoted in the margin, incorporating the information previously discussed with petitioner at his 1952 hearing before the IERB.14

*485On April 28, 1954, more than one year after the Secretary took action, and for the two days thereafter, petitioner presented his case to the EIPSB and was cross-examined in detail. The hearing began with a *486statement by the Chairman, which included the following passage:

“The transcript to be made of this hearing will not include all material in the file of the case, in that, it will not include reports of investigation conducted by the Federal Bureau of Investigation or other investigative agencies which ¿re confidential. Neither will it contain information concerning the identity of confidential informants or information which will reveal the source of confidential evidence. The transcript will contain only the Statement of Reasons, your answer thereto and the testimony actually taken at this hearing.”

Petitioner was again advised that the revocation of his security clearance was based on incidents occurring between 1942 and 1947, including his associations with alleged Communists, his visits with officials of the Russian Embassy, and the presence in his house of Communist literature.

Petitioner, in response to a question, stated at the outset of the hearing that he was then employed at a salary of $4,700 per year as an architectural draftsman and that he h¿d' been receiving $18,000 per year as Vice President and General Manager of ERCO. He later explained that *487after his discharge from ERCO he had unsuccessfully tried to' obtain employment in the aeronautics field but had been barricaded from it because of lack of clearance.15

Petitioner was subjected to an intense examination sim- ' ilar to that which he experienced before the IERB in 1952. .During the course of the examination, the Board injected new subjects of inquiry and made it evident that it was relying on various investigatory reports and statements of confidential informants which were not made available to petitioner.16 Petitioner reiterated in great detail the *488explanations' previously given before the IERB. He was subjected to intense cross-examination, however, concerning reports that he had agreed with the views held by his ex-wife.

*489Petitioner again presented a number of witnesses who testified that he was loyal, that he had spoken approvingly of the United States and its economic system, that he was a valuable engineer, and that he had made valuable and significant contributions to this country’s war efforts during World War II and the Korean War.

Soon'after the conclusion of the hearing, the-EIPSB notified petitioner that it had affirmed the Secretary’s action and that it had decided that the granting of clearance to petitioner for access to classified information was “not clearly consistent with the interests of national security.” Petitioner requested that he be furnished with a detailed statement of findings supporting the Board’s decision. He was informed, however, that s'ecurity con*490siderations prohibited such disclosure.17- On September 16, 1955, petitioner requested review by the Industrial Personnel Security Review Board.18 On March 12, 1956, almost three years after the Secretary’s action and nearly one year after the second hearing, he received a letter from the Director of the Office of Industrial Personnel Security Review informing him that the EIPSB had found that from 1942-1947 petitioner associated closely with his then wife and her friends, knowing that they were active in behalf of and sympathized with the Communist Party, that during part of this period petitioner maintained a sympathetic association with a number of officials of the Russian Embassy, that during this period petitioner’s political views were similar to those of his then wife, that petitioner had been a member of a suspect bookshop association, had invested money in a suspect radio station, had attended a suspect dinner, and had, on occasion,,. Communist publications in his home, and that petitioner’s credibility as a witness in the proceedings was doubtful. The letter also stated that the doubts concerning petitioner’s credibility affected the Board’s evaluation of his trustworthiness and that only trustworthy persons could be afforded access to classified information.19 The EIPSB determination was affirmed..

After the EIPSB decision in 1954, petitioner filed a complaint in the United States District Court for the Dis*491trict of Columbia asking for a declaration that the revocation was unlawful and void and for an order restraining respondents from acting' pursuant to it.20 He also asked for an order requiring respondents to advise ERCO that the clearance revocation was void. Following the affirmance of the EIPSB order by the Industrial Personnel Review Board, petitioner moved for summary judgment in the District Court. The Government cross-filed for dismissal of the complaint or summary judgment. The District Court granted the Government’s motion for summary judgment, 150 F. Supp. 958, and the' Court of Appeals affirmed that disposition, 103 U. S. App. D. C. 87, 254 F. 2d 944.

The Court of Appeals recognized that petitioner had suffered substantial harm from the clearance revocation.21 But in that court’s view, petitioner’s suit presented no “justiciable controversy” — no controversy which the courts could finally and effectively decide. This conclusion followed from the Court of Appeals’ reasoning that the Executive Department alone is competent to evaluate the competing considerations which exist in determining the persons who are to be afforded security clearances. *492The court also rejected petitioner’s claim that he was deprived of his livelihood without the traditional- safeguards required by “due process of law” such as-confrontation of his accusers and access to confidential reports used to determine his fitness. Central to this determination was the. court’s unwillingness to order the Government to choose between disclosing the identities of informants or giving petitioner clearance.

Petitioner contends that the action of the Department of Defense in barring him from access to classified information on the' basis óf statements of confidential informants made to investigators was not authorized by either Congress or the President and has' denied him “liberty” and “property” without “due process of Ism” in contravention of the Fifth Amendment. The alleged property is petitioner’s employment; the alleged liberty is petitioner’s freedom to practice his chosen profession. Respondents admit,-as they must, that the revocation of security clearance caused petitioner to lose his .job with ERCO and has seriously affected, if not destroyed, his ability to obtain employment' in the aeronautics field. Although the right to hold specific private employment and to follow a chosen profession free from unreasonable governmental interference comes within the “liberty” and “property” concepts of the Fifth Amendment, Dent v. West Virginia, 129 U. S. 114; Schware v. Board of Bar Examiners, 353 U. S. 232; Peters v. Hobby, 349 U. S. 331, 352 (concurring opinion); cf. Slochower v. Board of Education, 350 U. S. 551; Truax v. Raich, 239 U. S. 33, 41; Allgeyer v. Louisiana, 165 U. S. 578, 589-590; Powell v. Pennsylvania, 127 U. S. 678, 684, respondents contend that the admitted interferences which have occurred are indirect by-products of necessary governmental action to protect the integrity of secret information and hence are not unreasonable and do not constitute deprivations within the meaning, of the Amendment. *493Alternatively, respondents urge that even if petitioner has been restrained in the enjoyment of constitutionally protected rights, he was accorded due process of law in that he was permitted to utilize those procedural safeguards consonant with an effective clearance program, in the administration of which the identity of informants and their statements are kept secret to insure an unimpaired flow to the Government of information concerning subversive conduct. But in view of our conclusion that this case should be decided on the narrower ground of “authorization,” we find that we need not determine the answers to these questions.22

The issue, as we see it, is whether the Department of Defense has been authorized to create an industrial security clearance program under which affected persons may lose their jobs and may be restrained in following their chosen professions on the basis of fact determinations concerning their fitness for clearance made in proceedings in which they are denied the traditional procedural safeguards of confrontation and cross-examination.

Prior to World War II, only sporadic efforts were made to control the clearance of persons who worked in private . establishments which manufactured materials for national defense. Report .of the Commission on Government Security, 1957, S. Doc. No. 64, 85th Cong., 1st Sess. 236. During World War II the War Department instituted a *494formalized program to obtain the discharge from war plants of persons engaged in sabotage, espionage, and willful activity designed to disrupt the national defense program. Id., at 237. In 1946, the War Department began to require contractors, before being given access to classified information, to sign secrecy agreements which required consent before their employees were permitted access to Top Secret or Secret information. Id., at 238. At the outset, each armed service administered its own industrial clearance program. Id., at 239. Later, the PSB and IERB were established by the' Department of Defense and the Secretaries of the armed services to administer a more centralized program. Ibid. Confusion existed concerning the criteria and procedures to be employed by these boards. Ibid. Eventually, generalized procedures were established with the approval of the Secretaries which provided in part that before the IERB “[t]he hearing will be conducted in such manner as to protect from disclosure information affecting the national security or tending to' compromise investigative sources or methods . . . .” See “Procedures, Governing Appeals to the Industrial Employment Review Board, dated 7 November 1949,” note 4, supra, §4(c). After abolition of these boards in 1953, and the establishment of the IPSB, various new sets of procedures were promulgated which likewise provided for the non-disclosure of information “tending to compromise investigative sources or methods or the indentity of confidential informants.” 23

*495All of these programs and procedures were established .by directives issued by the Secretary of Defense or the Secretaries of the Army, Navy, and Air Force'. None was the creature of statute or of an' Executive Order issued by the President.24

Respondents maintain that congressional authorization to the President to fashion a program which denies security clearance to persons on the basis of confidential information which the individuals have no opportunity to confront and test is unnecessary because the President has inherent authority to maintain military secrets inviolate. And respondents argue that if a statutory grant of power is necessary, such a grant can readily be inferred “as a necessarily implicit authority from the generalized provisions” of legislation dealing with the armed services. *496But the question which must be decided in this case is not whether the. President has inherent power to act or whether Congress has granted him such a power; rather, it is whether either the President or Congress exercised such a power and delegated to the Department of Defense the authority to fashion such a program.

Certain principles have remained relatively immutable in our jurisprudence. One of these is that where governmental action seriously injures an individual, and the reasonableness of the action depends on fact findings, the evidence used to prove the Government’s case must be disclosed to the individual so that he has an opportunity to show that it is untrue. While this is important in the case of documentary evidence, it is even more important, where the evidence consists of the testimony of individuals whose memory might be faulty of who, in fact, might be perjurers or persons motivated by malice, vindictiveness, intolerance, prejudice, or jealousy. We have formalized these protections in the requirements of confrontation and cross-examinátion. They have ancient roots.25 They find expression in the Sixth Amendment which provides that in all criminal cases the accused shall enjoy the right “to be confronted with *497the witnesses against him.” This Court has been zealous to protect these rights from erosion. It has spoken out not only in criminal cases, e. g., Mattox v. United States, 156 U. S. 237, 242-244; Kirby v. United States, 174 U. S. 47; Motes v. United States, 178 U. S. 458, 474; In re Oliver, 333 U. S. 257, 273, but also in all types of cases where administrative and regulatory actions were under scrutiny. E. g., Southern R. Co. v. Virginia, 290 U. S. 190; Ohio Bell Telephone Co. v. Public Utilities Commission, 301 U. S. 292; Morgan v. United States, 304 U. S. 1, 19; Carter v. Kubler, 320 U. S. 243; Reilly v. Pinkus, 338 U. S. 269. Nor, as it has been pointed out; has Congress ignored these fundamental requirements in enacting regulatory legislation. Joint Anti-Fascist Committee v. McGrath, 341 U. S. 168-169 (concurring opinion).'

Professor Wigmore, commenting on the importance of cross-examination, states in his treatise, 5 Wigmore on Evidence (3d ed. 1940) § 1367:

“For two centuries past, the policy of the Anglo-American system of Evidence has been to regard the necessity of testing by cross-examination as a vital feature of the law. The belief that no safeguard for testing the value of human statements is comparable to that furnished by cross-examination, and the conviction that no statement (unless by special exception) should be used as testimony until it has been probed and sublimated by that test, has found increasing strength in lengthening experience.”

Little need be added to this incisive summary statement except to point out that under the present clearance procedures not only is the testimony of absent witnesses allowed to stand without the probing questions of the person under attack which often uncover inconsistencies, *498lapses of recollection,- and bias,26 but, in addition, even the members of the clearance boards do not see the informants. or know their identities, but normally rely on an investigator’s summary report of what the. in*499formant said without even examining the investigator personally.27

We must determine against this background, whether the President or Congress has delegated to the Depart*500ment of Defense the authority to by-pass these traditional and well-recognized safeguards in an industrial security cleárance program which can operate to injure individuals substantially by denying to them the opportunity to follow chosen private professions. Respondents cite two Executive Orders which they believe show presidential delegation. The first, Exec. Order No. 10290, 16 Fed. Reg. 9795, was entitled “Prescribing Regulations Establishing Minimum Standards For' The Classification, Transmission, And Handling, By Departments And *501Agencies of the Executive Branch, Of Official Information Which Requires Safeguarding In The Interest Of The Security Of The United States.” It provided, in relevant part:

“Part V — Dissemination of Classified Security Information

“29. General, a. No person shall be entitled to knowledge or possession of, or access to, classified security information solely by virtue of his office or position.

“b. Classified security information shall not be discussed with or in the presence of unauthorized persons, and the latter shall not be permitted to inspect or have access to such information.

“c. The head of each agency shall establish a system for controlling the dissemination of classified security information adequate to the needs of his agency.

“30. Limitations on dissemination — a. Within the Executive Branch. The dissemination of classified' security information shall be limited to persons whose official duties require knowledge of such information. Special measures shall be. employed to limit the dissemination of ‘Top Secret’ security information to the absolute minimum. Only that portion of ‘Top Secret’ security information necessary to the proper planning and appropriate action of any organizational unit or individual shall be released to such unit or individual.

“b. Outside ■ the Executive Branch. Classified security information shall not be disseminated outside the Executive Branch by any person or agency having access thereto or knowledge thereof except under conditions and through channels authorized by *502the head of the disseminating agency, even though such person or agency may have been solely or partly responsible for its production.”

The second, Exec. Order No. 10501, 18 Fed. Reg. 7049, which revoked Exec. Order No. 10290, is entitled “Safeguarding Official Information In The Interests Of The Defense Of The United States” and provides in relevant part:

“Sec. 7. Accountability and Dissemination.

“ (b) Dissemination Outside the Executive Branch. Classified defense information shall not be disseminated outside the executive branch except under conditions and through channels authorized by the head of the disseminating department or agency, even though the person or agency to which dissemination of such information is proposéd to be made may have been solely or partly responsible for its production.”

Clearly, neither of these orders empowers any executive agency to fashion security programs whereby persons are deprived of their present civilian employment and of the opportunity of continued activity in their chosen professions without being accorded the chance to challenge effectively the evidence and testimony upon which an adverse security determination might rest.28

Turning to the legislative enactments which might be deemed as delegating authority to the Department of Defense to fashion programs under which persons may be *503seriously restrained in their employment opportunities through a denial of clearance without the safeguards of cross-examination and confrontation, we note the Government’s own assertion, made in its brief, that “[w]ith petitioner’s contention that the Industrial Security Program is not explicitly authorized by statute we may readily agree . . .

The first proffered statute is the National Security Act of 1947, as amended, 5 U. S. C. § 171 et seq. That Act created the Department of Defense and gave to the Secretary of Defense and the Secretaries of the armed services the authority to administer their departments. Nowhere in the Act, or its amendments, is there found specific authority to create a clearance program similar to the one now in effect.

Another Act cited by respondents is the Armed Service Procurement Act of 1947, as amended. It provides in 10 U. S. C. § 2304 that:

“(a) Purchases of and contracts, for property or services covered by this chapter shall be made, by formal advertising. However, the head of an agency may negotiate such a purchase or contract, if—

“(12) the purchase or contract is for property or services whose procurement he determines should not be publicly disclosed because of their character, ingredients, or components.”

It further provides in 10 U. S. C. § 2306:

“(a) The cost-plus-a-percentage-of-cost system of contracting may not be used. Subject to this limitation and subject to subsections (b)-(e), the head of an agency may, in negotiating contracts under section 2304 of this title, make any kind of contract that he considers will promote the best interests of the United States.”

*504Respondents argue that these statutes, together with 18 U. S. C. § 798, which makes it a crime willfully and knowingly to communicate to unauthorized persons information concerning cryptographic or intelligence activities, and 50 U. S. C. § 783 (b), which makes it a crime for an officer or employee of the United States to communicate classified information to agents of foreign governments or officers and members of “Communist organizations,” reflect a recognition by Congress of .the existence of military secrets and the necessity of keeping those secrets inviolate.

Although these statutes make it apparent that Congress recognizes the existence of military secrets, they hardly constitute an authorization to create an elaborate clearance program which embodies procedures traditionally believed to be inadequate to protect affected persons.29

Lastly, the Government urges that if we refuse to adopt its “inferred” authorization reasoning, nevertheless, congressional ratification is apparent by the continued appropriation of funds to finance aspects of the program fashioned by the Department of Defense. Respondents refer us to Hearings before the House Committee on Appropriations on Department of Defense Appropriations for 1956, 84th Cong., 1st Sess. 774-781. At those hearings, the Committee was asked to approve the appropriation of funds to finance a program under which reimbursement for lost wages would be made to employees of government contractors who were temporarily denied, but later granted, security clearance. Apparently, such reim*505bursements had been made prior to that time out of general appropriations. Although a specific appropriation was eventually made for this purpose, it could not conceivably constitute a ratification of the hearing procedures, for the procedures were in no way involved in the special reimbursement program.30

*506Respondents’ argument on delegation resolves itself into the following: The President, in general terms, has authorized the Department of Defense to create procedures to restrict the dissemination of classified information and has apparently acquiesced in the elaborate program established by the Secretary of Defense even where application of the program results in restraints on traditional freedoms without the use of long-required procedural protections. Similarly, Congress, although it has not enacted specific legislation relating to clearance procedures to be utilized for industrial workers, has acquiesced in the existing Department of Defense program and has ratified it by specifically appropriating funds to finance one aspect of it.

If acquiescence or implied ratification were enough to show delegation of authority to take actions within the area of questionable constitutionality, we might agree with respondents that delegation has been shown here. In many circumstances, where the Government’s freedom to act is clear, and the Congress or the President has provided general standards of action and has acquiesced in administrative interpretation, delegation may be inferred. Thus, even in the absence of specific delegation, •we have no difficulty in finding, as we do, that the Department of Defense has been authorized to fashion and apply an industrial clearance program which affords affected persons the safeguards of confrontation and cross-examination. But this case does not present that situation. We deal here with substantial restraints on employment opportunities of numerous persons imposed in a manner which is in conflict with our long-accepted *507notions of fair procedures.31 Before we are asked to judge whether, in the context of security clearance cases, a person may be deprived of the right to follow his chosen profession without full hearings where accusers may be confronted, it must be made clear that the President or Congress, within their respective constitutional powers, specifically has decided that the imposed procedures are necessary and warranted and has authorized their use. Cf. Watkins v. United States, 354 U. S. 178; Scull v. Virginia, 359 U. S. 344. Such decisions cannot be assumed by acquiescence or non-action. Kent v. Dulles, 357 U. S. 116; Peters v. Hobby, 349 U. S. 331; Ex parte Endo, 323 U. S. 283, 301-302. They must be made explicitly.not only to assure that individuals are not deprived of cherished rights under procedures not actually authorized, see Peters v. Hobby, supra, but also because explicit action, especially in areas of doubtful constitutionality, requires careful and purposeful consideration by those responsible for enacting and implementing our laws. Without explicit action by lawmakers, decisions of great constitutional import and effect would be relegated by default to administrators who, under our system of government, are not endowed with authority to decide them.

Where administrative action has raised serious constitutional problems, the Court has assumed that Congress or the President intended to afford those affected by the action the traditional safeguards of due process. See, e. g., The Japanese Immigrant Case, 189 U. S. 86, 101; Dismuke v. United States, 297 U. S. 167, 172; Ex parte Endo, 323 U. S. 283, 299-300; American Power Co. v. Securities and Exchange Comm’n, 329 U. S. 90, 107-*508108; Hannegan v. Esquire, 327 U. S. 146, 156; Wong Yang Sung v. McGrath, 339 U. S. 33, 49. Cf. Anniston Mfg. Co. v. Davis, 301 U. S. 337; United States v. Rumely, 345 U. S. 41. These cases reflect the Court’s concern that traditional forms of fair procedure not be restricted by implication or without the most explicit action by the Nation’s lawmakers, even in areas where it is possible that the Constitution presents no inhibition.

In the instant case, petitioner’s work opportunities have been severely limited on the basis of a fact determination rendered after a hearing which failed to comport with our traditional ideas of fair procedure. The type of hearing was the product of administrative decision not explicitly , authorized by either Congress or the President. Whether those procedures under the circumstances comport with the Constitution we do not decide. Nor do we decide whether the President has inherent authority to create such a program, whether congressional action is necessary, or what the limits on executive or legislative authority may be. We decide only that in the absence of explicit authorization from either the President or Congress the respondents were not empowered to deprive petitioner of his job in a proceeding in which he was not afforded the safeguards of confrontation and cross-examination.

Accordingly, the judgment is reversed and the case is remanded to the District Court for proceedings not inconsistent herewith.

It is so ordered.

concurring specially.

What has been written on both sides of this case makes appropriate a further word from one who concurs in the judgment of the Court; but cannot join its opinion.

Unlike my brother Clark who finds this case “both clear and simple,” I consider the constitutional issue ■•’it presents most difficult and far-reaching. In my view the Court quite properly declines to decide it in the present posture of the case. My unwillingness to subscribe to the ..Court’s opinion is due to the fact that it unnecessarily deals with the very issue it disclaims deciding. For present purposes no more need be said than that we should not be drawn into deciding the .. constitutionality of the' security-clearance revocation procedures employed in' this case until the use' of such procedures in matters of this kind has been deliberately considered and expressly authorized by the Congress or the President who alone are in a position to evaluate' in the first instance the totality of factors bearing upon the necessity for their use. That much the courts are entitled to before they are asked to express a constitutional judgment upon an issue fraught with such important • consequences both to the Government and the citizen.

" Ample justification for abstaining from a constitutional decision at this stage of the case is afforded by the Court’s traditional and wise rule of not reaching constitutional issues unnecessarily or prematurely. That rule indeed has been consistently followed by this Court when faced with “confrontation” issues in .other security or loyalty cases. See Peters v. Hobby, 349 U. S. 331; Vitarelli v. Seaton, 359 U. S. 535; cf. Service v. Dulles, 354 U. S. 363; Kent v. Dulles, 357 U. S. 116. Adherence to that rule is, , as I understand it, the underlying basis of today’s decision, and it is on that basis that I join the judgment of the Court.

*510It is regrettable that my brother Clark should have so far yielded to the temptations of colorful characterization as to depict the issue in this case as being whether a citizen has “a constitutional right to have access to the Government’s military secrets,” and to suggest that the Court’s action today requires “the President’s Cabinet members to revoke their refusal to give” the petitioner “access to military , secrets,” despite any views they may have as to his reliability. Of course this decision involves no such issue or consequences. The basic constitutional issue is not whether petitioner is entitled to access to classified material, but rather whether, the particular procedures here employed to deny clearance on security grounds were constitutionally permissible; With good reason we do not reach that issue as matters now stand. And certainly there is nothing in the Court’s opinion which suggests that petitioner must be given access to classified material.

dissenting.

To me this case is both clear and simple. The respondents, all members of the President’s Cabinet, have, after a series of hearings, refused to give Greene further access to certain government military information which has been classified “secret.” The pertinent Executive Order defines “secret” information as

“defense information or material the unauthorized disclosure of which could result in serious damage to the Nation, such as by jeopardizing the international relations of the United States, endangering the effectiveness of a program or policy of vital importance to the national defense, or compromising important military or defense plans, scientific or technological developments important to national defense, or information revealing important intelli*511gence operations.” Exec. Order No. 10501, Nov. 5, 1953, 18 Fed. Reg. 7049, 3 CFR (1949-1953 Comp.), p. 979, § 1 (b).

Surely one does not have a constitutional right, to have access to the Government’s military secrets.1 But the Court says that because of the refusal to grant Greene further access, he has lost his position as vice president and general manager, a chief executive officer, of ERCO, whose business was devoted wholly to defense contracts with the United States,2 and that his training in aeronautical engineering, together with the facts that ERCO engages solely in government work and that the Government is the country’s largest airplane customer, has in some unaccountable fashion parlayed his employment with ERCO into “a constitutional right.” What for anyone else would be considered a privilege at best has for Greene been enshrouded in constitutional protection. This sleight of hand is too much for me.

But this is not all. After holding that Greene has constitutional protection for his private job, the Court has ordered the President’s Cabinet members to revoke their refusal to give Greene access to military secrets.3 It *512strikes down the present regulations as being insufficiently authorized by either the President or the Congress because the procedures fail' to provide for confrontation or cross-examination at Board hearings.. Let us first consider that problem:

I. The Constitutional Issue.

After full consideration the Court concludes “that in the absence of explicit authorization 'from either the President or Congress the respondents were not empowered to deprive petitioner of his job in a proceeding in which he was not afforded the safeguards of confrontation and cross-examination.” In so doing, as I shall point out, it holds for naught the Executive Orders of both President Roosevelt and President Truman andv the directives pursuant thereto of every Cabinet officer connected with our defense since 1942 plus the explicit order of General Dwight D. Eisenhower as Chief of Staff in 1946. In addition, contrary to the Court’s conclusion, the Congress was not only fully informed but had itself published the very procedures used in Greene’s case. '

I believe that the Court is in error in holding, as it must, in order to .reach this “authorization” issue, that Greene’s “right to hold specific private employment and to follow a chosen profession free from unreasonable governmental interference” is protected by the Fifth Amendment. It cites four cases in support -of this proposition and says compare four others. As I-read those cases-not *513one is in point.4 In fact, I cannot find a single case' in support of the Court’s position. Even a suit for damages on the ground of interference with private contracts does not lie against the Government. The Congress specifically exempted such suits from the Tort Claims Act. 28 U. S. C. § 2680 (h). But the action today may-have the effect of by-passing that exemption since Greene will now claim, as has Vitarelli, see Vitarelli v. Seaton, 359 U. S. 535 (1959), reimbursement for bis loss of wages. See Taylor v. McElroy, post, p. 709. This will date back to 1953. His salary at that time was $18,000 a year.

In holding that the Fifth Amendment protects Greene the Court ignores the basic consideration in the case, namely, that no person, save the President, has a constitutional right to access to governmental secrets. Even though such access is necessary for one to keep a job *514in private industry, he is still not entitled to the secrets. It matters not if as a consequence he is unable to secure a specific job or loses one he presently enjoys. The simple reason for this conclusion is that he has no constitutional right to the secrets. If access to its secrets is granted by the Government it is entirely permissive and may be revoked at any time. That is all that the Cabinet officers did here. It is done every day in governmental operation. The Court seems to hold that the access granted Greene was for his benefit: It was not. Access was granted to secure for the Government the supplies or services it needed. The contract with ERCO specifically provided for the action taken by the Cabinet officers. Greene as General Manager of ERCO knew of its provisions. If every person working on government contracts has the rights Greene is given here the Government is indeed in a box. But as was said in Perkins v. Lukens Steel Co., 310 U. S. 113, 127-128 (1940):

“Like private individuals and businesses, the Government enjoys the unrestricted power to produce its own supplies, to determine those with whom it will deal, and to fix the terms and conditions upon which it will make needed purchases. . . . Judicial restraint of those who administer the Government’s purchasing would constitute a break with settled judicial practice and a departure into fields hitherto wisely and happily apportioned by the genius, of our polity to the administration of another branch of Government.”

The Court refuses to pass on the constitutionality of the procedures used in the hearings. It does say that the hearings provided for in the program permit the restraint of “employment opportunities through a denial of clearance without the safeguards of confrontation and cross-examination.” I think the Court confuses admin*515istrative action with judicial trials. This Court has long ago and repeatedly approved administrative action where the rights of cross-examination and confrontation were not permitted. Chicago & Southern Air Lines v. Waterman Corp., 333 U. S. 103 (1948); Carlson v. Landon, 342 U. S. 524 (1952); United States v. Nugent, 346 U. S. 1 (1953); United States v. Reynolds, 345 U. S. 1 (1953); Knauff v. Shaughnessy, 338 U. S. 537 (1950); Shaughnessy v. Mezei, 345 U. S. 206 (1953); and Jay v. Boyd, 351 U. S. 345 (1956).

At no time since the programs now in vogue were established in 1942 have the rights of cross-examination and confrontation of witnesses been required. In fact the present regulations were patterned after the Employee Loyalty Program, first inaugurated upon the passage of the Hatch Act in 1939, in which the rights of confrontation and cross-examination have never been recognized. Every Attorney General since that time has approved these procedures, as has every President. And it should be noted, though several cases here have attacked the regulations on this ground, this Court has yet to strike them down.5

■ I shall not labor the point further than to say that in my opinion the procedures here do comport with that fairness required of administrative action in the security field. A score of our cases, as I have cited, support me in this position. Not one is to the contrary. And the action of the Court in striking down the program for lack of specific authorization is indeed strange, and hard for me to understand at this critical time of national emergency. The' defense establishment should know — and now— whether its program is constitutional and, if not, wherein *516it is deficient. I am sure that it will remember that in other times of emergency — no more grave than the present — it was permitted, without any hearing whatsoever— much less with confrontation and cross-examination — to remove American citizens from their homes on the West Coast and place them in concentration camps. See Hirabayashi v. United States, 320 U. S. 81 (1943); Korematsu v. United States, 323 U. S. 214 (1944). My examination of the Japanese exclusion orders indicates clearly that the Executive Order was a general authorization just as the two here. Congress at the time only created criminal offenses for violation of exclusion or curfew orders of the military commander. Likewise we have criminal statutes here. And while the Japanese orders were in time of war, those involved here had their inception in war and have been continued during the national emergency declared by the President. No one informed in present world affairs would say that our safety is less in jeopardy today. In fact we are now spending nearly as much money to protect it as during the war period. In this light it is inescapable that the existing authorizations áre entirely sufficient. Let us examine-them.

II. The President and the Congress Have Granted Sufficient Authority' to the -Cabinet Officers.

Since 1941 the industrial security program has been in operation under express directives from the President. Within a week after the attack on Pearl Harbor, President Roosevelt issued Exec. Order No. 8972, 6 Fed. Reg. 6420, Dec. 12, 1941, which authorized both the Secretary of War. arid the Secretary of the Navy “to establish and maintain military guards and patrols, and to take other appropriate measures, to protect from injury and destruction national-defense material, national-defense premises, and national-defense utilities, . . ” (Einphasis added.) *517In 1942, under the authority of that Executive Order, the Secretary of War undertook the formulation and execution of a program of industrial security.6 The procedures in. operation from 1942 and 1943 are outlined in a 1946 :. publication of the. Department of War entitled “Suspension of Subversives from Privately Operated Facilities of .Importance to the Security of the Nation’s Army and Navy Programs.”7 Interestingly enough, the instructions were issued in time of peace, did not give the suspect a hearing, and were signed by the then Chief of Staff— now President — Dwight D. Eisenhower.

In 1947, the National Security Act, 61 Stat. 495, effected a reorganization of the military departments and placed the Secretary of Defense at the head of the National Military Establishment. Section 305 (a) of the Act transferred to the new organization “[a] 11 laws, orders, regulations, and other actions applicable with respect to any function . . . transferred under this Act . . . .” Section 213 created a Munitions Board *518within the military establishment and under the supervision of the Secretary of Defense. Among its functions were

“(1) to coordinate the appropriate activities within the National Military Establishment with regard to industrial matters, including procurement . . . plans’. . . ; (2) to plan for the military aspects of industrial mobilization; . . . and (10) to perform such other duties as the Secretary of Defense may direct.” 8

In his first report to the President in 1948, Secretary of Defense Forrestal reported that:

“. . . the Munitions Board is responsible for necessary action to coordinate internal security within the National Military Establishment with regard to industrial matters. This work is being'planned and in some phases carried forward by the following programs:

“c. Development of plans and directives to protect classified armed forces information in the hands of industry from potential enemies;

“d. Establishment of uniform methods of handling of personnel clearances and secrecy agreements ....” First Report of the Secretary of Defense (1948) 102-103.

The forerunner of the exact program now in effect was put in operation in 1948 under the supervision of that Board. And, in the Annual'Report to the President, in 1949, the Secretary, then Louis Johnson, reported that

“Industrial Security. — A program to coordinate and develop uniform practices to ■ protect classified mili*519tary information placed in the hands of industry under procurement and research contracts was continued by the Munitions Board. Criteria were developed for the granting or denial of personnel and facility clearances in the performance of classified contracts. Work was started to establish a central security clearance register to centralize clearance data for ready reference by all departments and to prevent duplication in making clearance investigations. A joint Personnel Security Board administers this program, and the Industrial Employment Review Board hears appeals from security clearance denials.” Second Report of the Secretary of Defense, for the Fiscal Year 1949 (1950), 85.

Transmitted with that report to the President was the Annual Report of the Secretary of the Army, where the number-of security cases processed by the Army-Navy-Air Force Personnel Boards and the number of appeals handled by the Industrial Employment Review Board were detailed.9

Again in 1950 the Secretary of Defense informed the President, in a report required by law, of the statüs of the industrial security program.

“In the past 6 months, the Munitions Board activated the Industrial Employment Review Board, established ^procedures under which the latter will operate, and developed a set of uniform criteria stipulating the circumstances under which security clearances will be denied. The Munitions Board also established a Central Index Security Clearance File to serve as a clearing house for all individual and facility clearances and denials, [and] developed a standard security requirements check list . . . . *520Uniform standards for security investigations of facility and contractors’ personnel are being developed .... A standard military security agreement is being coordinated to bind potential suppliers to security regulations before a classified contract is awarded, and a manual to give security guidance to industry is being prepared.” Semiannual Report of the Secretary of Defense, July 1 to Dec. 31, 1949 (1950), 97.

The President, in 1953, in Reorganization Plan No. 6, 67 Stat. 638, transferred all of the “functions of the Munitions Board” to the Secretary of Defense and dissolved that Board. Since then the program has been in operation under the authority of the Secretary. Also in 1953, the President issued Exec. Order No. 10450, Apr. 27, 1953, 18 Fed. Reg. 2489, 3 CFR (1949-1953 Comp.), p. 936. That order dealt with the criteria and procedures to be used in the Federal Loyalty Security Program, which had been instituted under Exec. Order No. 9835, 12 Fed. Reg. 1935, 3 CFR (1943-1948 Comp.), p. 630, Mar. 21, 1947. The latter order made clear that federal employees suspected of disloyalty had no right of confrontation.10 And the regulations promulgated under the order provided no such right. See 13 Fed. Reg. 9365, 5 CFR (1949), § 210, Dec. 31, 1948. These procedures were revised under Exec. Order No. 10450, supra, although again, confrontation and cross-examination were not provided. See *52119 Fed. Reg. 1503, 32 CFR, p. 288, Mar. 19, 1954. Thus, it was clear that the President had not contemplated that there would be a right of confrontation in the Federal Loyalty Security Program. And the report' of the Secretary of the Army — transmitted to the President by the Secretary of Defense — made clear that the criteria of Exec. Order No. 1Ó450 were being utilized not only where the loyalty of a government employee was in doubt, but also in carrying out the industrial security program. Semiannual Report of the Secretary of the Army, Jan. 1, 1954, to June 30, 1954, 135-136.

Thus we see that the program has for 18 years been carried on under the express authority of the President, and has been regularly reported to him by his highest Cabinet officers. How the Court can say, despite these facts, that the President has not sufficiently authorized the program is beyond me, unless the Court means that it is necessary for the President to write out the Industrial Security Manual in his own hand.

Furthermore, I think Congress has sufficiently authorized the program, as it has been kept fully aware of its development and has appropriated money to support it. During the formative period of the program, 1949-1951, the Congress, through appropriation hearings, was kept fully informed as to the activity. In 1949 D. F. Carpenter, Chairman of the Munitions Board, appeared before a Subcommittee of the House Committee on Appropriations to testify concerning the requested appropriation for the Board. While the report indicates much of the testimony was “off the record,” it does contain specific references to the program here under attack.11 Significantly the appropriation bill for 1950 included an item *522of $11,300,000 for' the maintenance, inter alia, of the Board.

Again, in 1950 General Timber lake, a member of the Board, testified:

“Then we are going to intensify the industrial mobilization planning within the Department of Defense, with particular emphasis on industrial security . . : House of Representatives, Hearings before a Subcommittee of the Committee on Appropriations. on the Supplemental Appropriation for 1951, 81st Cong., 2d Sess. 264.

While, again, some of the testimony was “off the record” it was sufficiently urgent and detailed for the Congress to appropriate additional funds for the Board for 1951.12

By the 1953 Reorganization Plan, the functions of the Munitions Board were transferred to varioús Assistant Secretaries of Defense. The industrial security program was put under the Assistant Secretary of Defense for Manpower, Personnel, and Reserve Forces. Of course, this office received an appropriation each year. These hearings, to cite but two, certainly indicate an awareness *523on the part of Congress of the existence of the industrial security program, and the continued appropriations hardly bespeak an unwillingness on the part of Congress that it be carried on. In 1955, the Eighty-fourth Congress, on the motion of Senator Wiley for unanimous consent, caused to be printed the so-called Internal Security Manual^ S. Doc. No. 40, 84th Cong., 1st Sess. It is a compilation of all laws, regulations, and congressional committees relating to the national security. Contained in the volume is the “Industrial Personnel Security Review Regulation,” i. e., a verbatim copy of the regulations set up by the Secretary of Defense on February 2, 1955. This Manual outlined in detail the hearing procedures which are here condemned by the Court. And it is important to note that the final denial of Greene’s clearance was by a Board acting under these very regulations. Still not one voice was raised either within or without the Halls of Congress that the Defense Department had exceeded its authority or that contractor employees were being denied their constitutional rights. In other cases we have held that the inaction of the Congress, in circumstances much less specific than here, was a clear ratification of a program as it was then being carried out by the Executive. Why, I ask, do we not do that here where it is so vital? We should not be “that blind Court . . . that does not see what '[a] 11 others can see and understand ....’” United States v. Rumely, 345 U. S. 41, 44 (1953).

While it cértainly is not clear to me, I suppose that the present fastidiousness of the Court can be satisfied by the President’s incorporating the present industrial security program into a specific Executive Order or the Congress’ placing it on the statute books. To me this seems entirely superfluous in light of the clear authorization presently existing in the Cabinet officers. It also subjects the Government to multitudinous actions — and perhaps large *524damages — by reason of discharges' made pursuant to the present procedures.

And I might add a nota bene. Even if the Cabinet officers are given this specific direction, the opinion today, by dealing so copiously with the constitutional issues, puts a cloud over' both the Employee Loyalty Program and the one here under attack. Neither requires that hearings afford confrontation or cross-examination. While the Court disclaims deciding this constitutional question, no one reading the opinion will doubt that the explicit laniguage of its broad sweep speaks in prophecy. Let us hope that the winds may change. If they do not the present temporary debacle will turn into a rout of our internal security.
