delivered the opinion of the Court.
This is a suit for reclassification of federal civil service positions and for backpay. It presents a substantial issue concerning the jurisdiction of the Court of Claims and the relief available in that tribunal.
I
The plaintiff-respondents, Herman R. Testan and Francis L. Zarrilli, are trial attorneys employed in the Office of Counsel, Defense Personnel Support Center, Defense Supply Agency, in Philadelphia. They represent the Government in certain matters that come before the Armed Services Board of Contract Appeals of the Department of Defense. Their positions are subject to the Classification Act, 5 U. S. C. § 5101 et seq., and they are presently classified at civil service grade GS-13.
In December 1969 respondents, through their Chief Attorney, requested their employing agency to reclassify their positions to grade GS-14. The asserted ground was that their duties and responsibilities met the requirements for the higher grade under standards promulgated *394 by the Civil Service Commission in General Attorney Series GS-905-0. In addition, they contended that their duties were identical to those of other trial attorneys in positions classified as GS-14 in the Contract Appeals Division, Office of the Staff Judge Advocate, Headquarters, Air Force Logistics Command, Wright-Patterson Air Force Base, Dayton, Ohio, and that under the principle of “equal pay for substantially equal work,” prescribed in § 5101 (1)(A), 1 they were entitled to the higher classification.
The agency, after an audit by a position classification specialist, concluded that the respondents’ assigned duties were properly classified at the GS-13 level under the Commission’s classification standards. On appeal, the Commission reached the same conclusion and denied reclassification. The Commission also ruled that comparison of the positions held by the respondents with those of attorneys employed by the referenced Logistics Command was not a proper method of classification.
The two respondents then instituted this suit in the Court of Claims. 2 Each sought an order directing reclassification of his position as of the date (May 8, 1970) of the first administrative denial of his request, and back-pay, computed at the difference between his salary and grade GS-14 (and the claimed appropriate within-grade step), from that date. The trial judge, in a long opinion, App. 43-117, concluded that the respondents were not *395 entitled to backpay due to their allegedly wrongful'classi-fieation. Id., at 57. But he also concluded that the Commission’s refusal to reclassify respondents to GS-14 was arbitrary, discriminatory, and not supported by substantial evidence, ibid., and that as a matter of law the respondents were entitled to an order remanding the case to the Commission with directions so to. reclassify the respondents. Id., at 58, 117.
The Court of Claims considered the case en banc and divided 4-3. The majority disapproved the trial judge’s recommendation that the court was empowered to direct the reclassification of respondents to GS-14, for the Court of .Claims is not authorized to create an entitlement to a governmental position. “If entitlement depends on the exercise of discretion by someone else we cannot substitute our own discretion.”
The majority agreed with the trial judge that the Commission’s failure to compare respondents’ positions with those of the Logistics Command attorneys was arbitrary and capricious.
Id.,
at 331,
The dissent argued that the jurisdiction of the Court of Claims is limited to money judgments and, since none had been or could be ordered in this case, the court was without jurisdiction even to remand the case to the Civil Service Commission. In addition, the respondents had not stated a claim upon which relief could be granted, for they were asking for positions, and pay, to which they had never been appointed. The dissent further argued that there is no constitutional right to a governmental position to which one has not been appointed; that the salary of a Government job is payable only to the person appointed to that position; and that the court has no authority to take over the appointing power that the Constitution, Art. II, § 2, has placed in the Executive Department. It asserted that the decision of the majority was but a declaratory judgment, a legal function not within the court’s jurisdiction. Finally, the dissent argued that the classification decision of the Commission was neither arbitrary nor capricious and was supported by substantial evidence.
*397
We granted certiorari because of the importance of the issue in the measure of the Court of Claims' statutory jurisdiction, and because of the significance of the court's decision upon the Commission's administration of the civil service classification system.
II
We turn to the respective statutes that are advanced as support for the action taken by the Court of Claims.
A. The Tucker Act. The central provision establishing the jurisdiction of the court is that part of the Tucker Act now codified as 28 U. S. C. § 1491:
"The Court of Claims shall have jurisdiction to render judgment upon any claim against the United States founded either upon the Constitution, or any Act of Congress, or any regulation of an executive department, or upon any express or implied contract with the United States, or for liquidated or un-liquidated damages in cases not soui~ding in tort." 4
This Court recently had occasion to examine the jurisdiction of the Court of Claims under this statutory formulation. In United States v. King,
The Tucker Act, of course, is itself only a jurisdictional statute; it does not create any substantive right enforceable against the United States for money damages. The Court of Claims has recognized that the Act merely confers jurisdiction upon it whenever the substantive right exists.

United States,
B. The Classification Act. Inasmuch as the trial judge
*399
proposed, App. 57, that the respondents were not entitled to backpay under the Back Pay Act, 5 U. S. C. § 5596, and the Court of Claims held that there was no need for it to reach and construe that Act,
It long has been established, of course, that the United States, as sovereign, “is immune from suit save as it consents to be sued . . . and the terms of its consent to be sued in any court define that court’s jurisdiction to entertain the suit.”
United States
v.
Sherwood,
We find no provision in the Classification Act that expressly makes the United States liable for pay lost through allegedly improper classifications. To be sure, in the “purpose” section of the Act, 5 U. S. C. § 5101 (1)(A), Congress stated that it was “to provide a plan for classification of positions whereby . . . the principle of equal pay for substantially equal work will be followed.” And in subsequent sections, there are set forth substantive standards for grading particular positions, and provisions for procedures to ensure that those standards are met. But none of these several sections contains an express *400 provision for an award of backpay to a person who has been erroneously classified.
In answer to this fact, the respondents and the amid make two observations. They first argue that the Tucker Act fundamentally waives sovereign immunity with respect to any claim invoking a constitutional provision or a federal statute or regulation, and makes available any and all generally accepted and important forms of redress, including money damages. It is said that the Government has confused two very different issues, namely, whether there has been a waiver of sovereignty, and whether a substantive right has been created, and it is claimed that where there has been a violation of a substantive right, the Tucker Act waives sovereign immunity as to all measures necessary to redress that violation.
The argument does not persuade us. As stated above, the Tucker Act is merely jurisdictional, and grant of a right of action must be made with specificity. The respondents do not rest their claims upon a contract; neither do they seek the return of money paid by them to the Government. It follows' that the asserted entitlement to money damages depends upon whether any federal statute “can fairly be interpreted as mandating compensation by the Federal Government for the damage sustained.”
Eastport S. S. Corp.
v.
United States,
We perceive nothing in the
Regional Rail Reorganization Act Cases,
The respondents and the amici next argue that the violation of any statute or regulation relating to federal employment automatically creates a cause of action against the United States for money damages because, if this were not so, the employee would then have a right without a remedy, inasmuch as he is denied access to the one forum where he may seek redress. 5
Here again we are not persuaded. Where the United States is the defendant and the plaintiff is not suing for money improperly exacted or retained, the basis of the federal claim — whether it be the Constitution, a statute,
*402
or a regulation — does not create a cause of action for money damages unless, as the Court of Claims has stated, that basis “in itself... can fairly be interpreted as mandating compensation by the Federal Government for the damage sustained.”
Eastport S. S. Corp.
v.
United States,
The present action, of course, is not one concerning a wrongful discharge or a wrongful suspension. In that situation, at least since the Civil Service Act of 1883, the employee is entitled to the emoluments of his position until he has been legally disqualified.
United States
v.
Wickersham,
The case of
Selman
v.
United States,
The situation, as we see it, is not that Congress has left the respondents remediless, as they assert, for their allegedly wrongful civil service classification, but that Congress has not made available to a party wrongfully classified the remedy of money damages through retroactive classification. There is a difference between prospective reclassification, on the one hand, and retroactive reclassification resulting in money damages, on the. other. See
Edelman
v.
Jordan,
The respondents, thus, are not entirely without remedy. They are without the remedies in the Court of Claims *404 of retroactive classification and money damages to which they assert they are entitled. Additional remedies of this kind are for the Congress to provide and not for the courts to construct.
Finally, we note that if the respondents were correct in their claims to retroactive classification and money damages, many of the federal statutes — such as the Back Pay Act — that expressly provide money damages as a remedy against the United States in carefully limited circumstances would be rendered superfluous.
The Court of Claims, in the present case, sought to avoid all this by its remand to the Civil Service Commission for further proceedings. If, then, the Commission were to find that the respondents were entitled to a higher grade, the Court of Claims announced that it would be prepared on appropriate motion to enter ah award of money damages for the respondents for whatever backpay they lost during the period of their wrongful classifications.

v.
United States,
C. The Back Pay Act. This statute, which the Court of Claims found unnecessary to evaluate in arriving at its decision, does not apply, in our view, to wrongful-classification claims. The Act does authorize retroactive recovery of wages whenever a federal employee has “undergone an unjustified or unwarranted personnel action that has resulted in the withdrawal or reduction of all or a part of” the compensation to which the employee is otherwise entitled. 5 U. S. C. § 5596 (b). The statute’s language was intended to provide a monetary remedy for wrongful reductions in grade, removals, suspensions, and “other unwarranted or unjustified actions affecting pay or allowances [that] could occur in the course of reassignments and change from full-time to part-time work.” S. Rep. No. 1062, 89th Cong., 2d
*406
Sess., 3 (1966). The Commission consistently has so construed the Back Pay Act. See 5 CFR § 550.803 (e) (1975). So has the Court of Claims. See
Desmond
v.
United States,
For many years federal personnel actions were viewed as entirely discretionary and therefore not subject to any judicial review, and in the absence of a statute eliminating that discretion, courts refused to intervene where an employee claimed that he had been wrongfully discharged. Compare
Keim
v.
United States,
Congress, of course, now has provided specifically in the Lloyd-LaFollette Act, 5 U. S. C. § 7501, for administrative review of a claim of wrongful adverse action, and in the Back Pay Act for the award of money damages for a wrongful deprivation of pay. But federal agencies continue to have discretion in determining most matters relating to the terms and conditions of federal employment. One continuing aspect of this is the rule, mentioned above, that the federal employee is entitled to receive only the salary of the position to which he was appointed, even though he may have performed the duties of another position or claims that he should have been placed in a higher grade. Congress did not override this rule, or depart from it, with its enactment of the Back Pay Act. It could easily have so provided had that been its intention. 8
*407
In support of their contention that the Back Pay Act authorizes a claim in the situation here presented, respondents and
amici
cite only two cases other than the Court of Claims cases whose reasoning is directly in question here. Neither case supports the proposition.
Walker
v.
Kleindienst,
Neither of these cases provides a reason for doubting that the Back Pay Act, as its words so clearly indicate, was intended to grant a monetary cause of action only to those who were subjected to a reduction in their duly appointed emoluments or position.
III
We therefore conclude that neither the Classification Act nor the Back Pay Act creates a substantive right in the respondents to backpay for the period of their claimed wrongful classifications. This makes it unnecessary for us to consider the additional argument advanced by the United States that the Classification Act does not require that positions held by employees of one agency be compared with those of employees in another agency.
The Court of Claims was in error when it remanded the case to the Civil Service Commission for further proceedings. That court’s judgment is therefore reversed, *408 and the case is remanded with directions to dismiss the respondents’ suit.
It is so ordered.

There is no suggestion that the plaintiff-respondents have not properly pursued and exhausted their administrative remedies.
The decision of the Court of Claims in this case is not inconsistent, as to these issues, with other recent cases resolved by divided votes in that court. See

Title 28 U. S. C. § 1494 also grants the Court of Claims jurisdiction to determine the amount due from the United States "by reason of any unsettled account of any officer . of . the United State."
The amici acknowledge that it is conceivable that the respondents will be able to obtain reclassification for the future through the mandamus action they instituted in 1971. See Testan v. Hampton, Civ. No. 71-2250 (ED Pa.). That suit apparently lies dormant subject to reactivation. The Government states that if respondents proceed with the action, the United States “will not contest the district court’s jurisdiction to entertain respondents’ claim for prospective equitable relief.” Reply Brief for United States 17 n. 7.

The committee reports relating to Pub. L. 92-415 expressly confirm the understanding that the remand statute “does not extend the class of cases over which the Court of Claims has jurisdiction.” S. Rep. No. 92-1066, p. 1 (1972); H. R. Rep. No. 92-1023, p. 3 (1972).
