Opinion for the Court filed by Circuit Judge WILLIAMS.
This case requires us to answer two important questions in the area of federal employment. First, we must decide the scope of Congress’s preclusion of judicial review of decisions of the Federal Labor Relations Authority (“FLRA” or “Authority”). Second, because we conclude that Congress did not intend to cut off review of constitutional claims, we must decide whether federal civil service employees have a “property” interest, of the sort protected by the Due Process clause of the Fifth Amendment, in annual within-grade pay increases. We find that they do not.
I. Background
In June 1982 the Internal Revenue Service denied a within-grade pay increase to one of its employees, Jacqueline Tommas Griffith, on the grounds that she was not performing at “an acceptable level of competence.” See 5 U.S.C. § 5335(a)(3)(B) (1982) (establishing that standard for such increases). Pursuant to 5 C.F.R. § 531.410 (1982), Griffith asked the agency to reconsider its decision. In preparing for this process, Griffith asked that her supervisor allow her to review documents relating to the denial. The supervisor refused to supply them, stating that they were either reports Griffith had prepared or reviews that she had previously received. The arbitrator later held, and the FLRA appeared to concede, that this withholding violated applicable regulations. See 5 C.F.R. § 531.410(a)(2); Joint Appendix (“J.A.”) at 9; NTEU v. IRS, 17 FLRA 1058, 1059 (May 13, 1985). On reconsideration, the IRS again denied the increase. In so doing, it relied on several documents not provided to Griffith, again in violation of 5 C.F.R. § 531.410(a)(2).
Griffith next turned to arbitration under the grievance procedure established by the collective bargaining agreement between the National Treasury Employees Union and the IRS. Before the arbitrator, the union argued that the IRS had violated relevant procedural regulations in its reconsideration of the denial of Griffith’s pay increase, and that these violations entitled her to a retroactive pay increase with back pay under the Back Pay Act, 5 U.S.C. § 5596 (1982). The arbitrator largely agreed and awarded Griffith the retroactive pay hike.
The IRS filed exceptions with the FLRA pursuant to 5 U.S.C. § 7122 (1982), and prevailed there. The FLRA held that the Back Pay Act authorized retroactive awards of within-grade increases only where there is a finding that “but for” the procedural violation the agency would have viewed the employee’s performance as meeting the statutory standard. The Authority held the arbitrator’s award to be contrary to the Back Pay Act because he had not made such a finding. Additionally, the Authority held that the “harmful error” standard of 5 U.S.C. § 7701(c) applied only to the appellate procedures of the Merit Systems Protection Board, and not to decisions by arbitrators.
The FLRA responded to these flaws in the arbitrator’s decision not by remanding to him but by striking the retroactive within-grade increase. The union then moved for reconsideration of the decision on several grounds, specifically requesting remand to the arbitrator. The Authority denied the motion, asserting that the arguments presented by the union “constitute nothing more than disagreement with the merits of the Authority’s decision.” J.A. at 32.
Having exhausted her administrative remedies, the plaintiff turned to the district court. In June 1986 she brought a suit for declaratory and injunctive relief against the Authority, alleging that the FLRA had erred as a matter of law in its construction *490 of the Back Pay Act and, in the alternative, that the refusal of the Authority to remand her case to an arbitrator denied her due process. The district court granted the Authority’s motion for summary judgment, holding that 5 U.S.C. § 7123(a) (1982) barred judicial review of non-constitutional claims, and that Griffith could not make out a colorable due process claim because she had no legitimate claim of entitlement to a within-grade pay increase. This appeal followed.
We first address the availability of judicial review for nonconstitutional claims. We find unusually clear congressional intent generally to foreclose review. Although we find that the statute leaves the door ajar for review of clear violations of statutory authority under
Leedom v. Kyne,
Turning to constitutional challenges, we find that under this court’s decision in
Ralpho v. Bell,
II. Reviewability of Non-Constitutional Claims
A. General preclusion of review
The controlling statute is a provision of the Civil Service Reform Act of 1978 (“CSRA”), 1 5 U.S.C. § 7123(a) (1982), which provides so far as is relevant:
Any person aggrieved by any final order of the Authority other than an order under—
(1) section 7122 of this title (involving an award by an arbitrator), unless the order involves an unfair labor practice under section 7118 of this title ...,
may ... institute an action for judicial review of the Authority's order in the United States court of appeals in the circuit in which the person resides or transacts business or in the United States Court of Appeals for the District of Columbia.
5 U.S.C. § 7123(a) (1982) (emphasis added).
Our construction of this language is informed by the general presumption favoring judicial review in the absence of “clear and convincing evidence of a contrary legislative intent,”
Abbott Laboratories v. Gardner,
We are convinced that as a general matter Congress intended to preclude judicial review in the district courts of FLRA decisions concerning arbitral awards. § 7123 provides for circuit court review of FLRA final orders, but then explicitly excludes orders under § 7122 relating to FLRA decisions on arbitral awards. 2 From that exclusion Congress makes a discrete exception for orders involving unfair labor *491 practices. No one suggests that the exception is applicable here. Therefore, contrary to the appellant’s contention, we need not resort to “negative inference” to find a preclusion of review in § 7123; although the statute authorizes certain types of review and fails to mention others, it specifically excludes review of the type of Authority decisions here at issue.
Thus it is hardly surprising that all circuit courts addressing the matter have concluded that § 7123 bars
circuit
court review of arbitral decisions not involving unfair labor practices.
Overseas Education Ass’n v. FLRA,
To be sure, Congress did not explicitly deny to
district
courts the power to review FLRA decisions. Nevertheless, where Congress has set out a complex scheme authorizing certain types of review but not others, the express preclusion of review of FLRA orders under § 7122 in the one mention of the subject powerfully suggests an intent to preclude review in every court.
See United States v. Fausto,
— U.S. —,
Further, Congress specified that the FLRA was to review arbitrators’ decisions on grounds “similar to those applied by Federal courts in private sector labor-management relations.” 5 U.S.C. § 7122(a). Congress thus appears to have intended that in the area of arbitral awards the Authority would play in federal labor relations the role assigned to district courts in private sector labor law. The conference report on the Civil Service Reform Act confirms this view, stating that, “The Authority will only be authorized to review the award of the arbitrator on very narrow grounds similar to the scope of judicial review of an arbitrator’s award in the public sector.” H.R.Rep. No. 1717, 95th Cong., 2d Sess. 153 (1978), U.S.Code Cong. & Admin.News 1978, pp. 2723, 2887. To give district courts review of FLRA decisions would tend to redundancy and would imperil the features of the arbitral process that we believe Congress had in mind when it set up the scheme: finality, speed and economy.
The legislative history of the CSRA further supports our conclusion. The House version of the bill provided for review in federal courts of appeal of virtually all FLRA decisions, including those FLRA orders concerning arbitral awards. H.R. 11,-280, 95th Cong., 2d Sess. § 701 (1978) (House version of § 7123 authorizing review at behest of “[a]ny person aggrieved by any final order of the Authority ... under section 7122 of this article (involving an award by an arbitrator)”). The Senate bill limited judicial review of the FLRA to unfair labor practice decisions, decisions involving constitutional issues, and decisions on exceptions to arbitrators’ awards based on unfair labor practice complaints. S. 2640, 95th Cong., 2d Sess. § 701 (1978) (Senate’s proposed § 7204(1) making all decisions of the Authority “final and conclusive” and stripping courts of jurisdiction to review, but allowing for review of “questions arising under the Constitution”). In conference, the House conferees acceded to the Senate view that FLRA decisions concerning arbitrator’s awards would be reviewable only in cases involving unfair labor practices. The conference report made this intention crystal clear:
The Senate Bill made reviewable in court decisions of the Authority concerning unfair labor practices, including awards of arbitrators relating to unfair labor practices. Otherwise, the Senate provides that all decisions of the Authority are final and conclusive, and not subject to further judicial review except for questions arising under the Constitution.
*492 In the House bill, unfair labor practice decisions are appealable as in the Senate. In addition, all other final decisions of the Authority involving an award by an arbitrator, and the appropriateness of the unit an organization seeks to represent are also appealable to the courts ...
[:T]here will be no judicial review of the Authority’s action on those arbitrators’ awards in grievance cases which are appealable to the Authority. The Authority will only be authorized to review the award of the arbitrator on very narrow grounds similar to the scope of judicial review of an arbitrator’s award in the private sector. In light of the limited nature of the Authority’s review, the conferees determined it would be inappropriate for there to be subsequent review by the court of appeals in such matters.
H.R.Rep. No. 1717, 95th Cong., 2d Sess. 153 (1978), U.S.Code Cong. & Admin.News 1978, p. 2887. (emphasis added). Thus, the conferees were faced with two very different schemes of judicial review of FLRA decisions, but consciously and explicitly chose the one cutting off review of decisions of the sort at issue in the instant case.
Our reading of the Act comports also with what we believe to have been a major object of the legislation: extending the benefits of arbitration in labor relations from the private to the public sector. In
The Steelworkers Trilogy,
the Supreme Court exalted the role of the arbitrator in labor-management disputes and set out a general policy of judicial deference to the decisions of arbitrators.
United Steelworkers v. American Manufacturing,
In sum, the specific language of § 7123, the structure of the CSRA arbitration and review provisions, and the relevant legislative history all provide clear and convincing evidence that Congress intended to cut off judicial review of FLRA decisions regarding arbitral awards of the sort involved in this case. Congress could hardly have made its view on the matter clearer.
B. The Leedom v. Kyne Exception.
Even where Congress is understood generally to have precluded review, the Supreme Court has found an implicit but narrow exception, closely paralleling the historic origins of judicial review for agency actions in excess of jurisdiction.
See generally
L. Jaffe,
Judicial Control of Administrative Action
327-36 (1965). The leading case is
Leedom v. Kyne,
*493
The
Leedom v. Kyne
exception is intended to be of extremely limited scope.
See Boire v. Greyhound Corp.,
In
Kyne
itself the Court stressed that the Board had acted “contrary to a specific prohibition in the Act” that was “clear and mandatory.”
The error asserted by Griffith — if error it be — is plainly not judicially correctable under Leedom v. Kyne. At stake in the FLRA proceeding was the proper test to be applied where review uncovers a procedural error in the personnel decision under review. The statute in question, the Back Pay Act, 5 U.S.C. § 5596(b)(1), does not address the matter expressly. It merely provides, in relevant part, that
An employee who ... is found by appropriate authority under applicable law, rule, regulation, or collective bargaining agreement, to have been affected by an unjustified or unwarranted personnel action which has resulted in the withdrawal or reduction of all or part of the pay, allowances, or differentials of the employee—
(a) is entitled ... to receive ...
(i) an amount equal to ... the pay ... which the employee normally would have earned or received during the period if the personnel action had not occurred....
5 U.S.C. § 5596(b)(1) (emphasis added).
The FLRA applied a so-called “but for” test, to wit, that the complaining employee *494 can secure back pay under the Act only if she can show that “but for the unwarranted violation [the procedural error], [she] would have received the within-grade increase.” NTEU v. IRS, 17 FLRA at 1059. Griffith claims that this construction is “clearly wrong and ... egregiously out of step with settled law under the Back Pay Act.” Appellant's Brief at 20.
It is readily apparent that the alleged error in the Authority’s “but for” test differs both in kind and in severity from the essentially jurisdictional error asserted in
Kyne.
Though not the only possible construction of the statutory language, it is surely a colorable one. Indeed, in
Professional Airways Systems v. FLRA,
Griffith also suggests that because 5 U.S.C. § 7122 provides that the Authority may only act in a manner “consistent with applicable laws,” the FLRA’s allegedly erroneous construction of the Back Pay Act placed it beyond the pale of its statutory authority. This, of course, seeks effectively to incorporate the Back Pay Act into the FLRA’s organic statute. Whatever support this might have in some circumstances, it has none where the legal error, if any, is at most one of failing to capture some marginal nuance of the Back Pay Act. Accepting such a claim would turn every error of law into a basis for review, effectively repealing hundreds of finality provisions. We do not believe that Congress desired such a result. Accordingly, the district court correctly concluded that it was without jurisdiction to review the appellant’s non-constitutional claims.
III. Constitutional Claims
A. Reviewability
Griffith asserts that the Authority’s disposition of her claim, particularly its failure to remand to the arbitrator, deprived her of “property,” namely her interest in an annual within-grade pay increase, without due process, in violation of the Fifth Amendment. Under circuit law, neither Congress’s language nor the legislative history of the CSRA is sufficient to preclude review of this claim.
The maxim that congressional preclusion of judicial review must be “clear and convincing” applies “in a particularly rigorous fashion,” we have said, when constitutional claims are at stake.
Bartlett v. Bowen,
Even though constitutional attacks on a
statute
carry much less risk of trammell-ing the administrative system than do claims that a particular act of an agency was unconstitutional, we have extended this “particularly rigorous” style of interpretation into the latter, more treacherous area. In
Ralpho v. Bell,
One might attempt to distinguish Ralpho and Ungar on the ground that both involve *495 allegations that the agency’s conduct had the effect of “taking” classical property rights. But nothing in the opinions’ language suggests an intent to limit their strong version of the “clear and convincing” test to such rights. Accordingly, we think it would be disingenuous to suggest that our “particularly rigorous” application of the “clear and convincing” standard is subject to such a limitation.
Here of course the statute itself does not specifically preclude review of constitutional claims. The only reference in the legislative history is a provision in the original Senate bill, explicitly providing for review of FLRA decisions involving questions arising under the Constitution. S. 2640, 95th Cong., 2d Sess. § 701 (1978) (Senate bill’s § 7204(1) making decisions of the Authority “final and conclusive” with exception for “questions arising under the Constitution”). The conference committee dropped the provision without explanation, in the course of generally moving to the Senate’s far more restrictive approach to judicial review.
See
H.R.Rep. 1717, 95th Cong., 2d Sess 153 (1978). This silent deletion is not enough, under our cases, to support an inference of intent to preclude constitutional claims.
See Ungar,
We therefore turn to the merits of plaintiff’s constitutional claim.
B. Merits: The Procedural Due Process Claim
In establishing a violation of her rights under the Due Process clause of the Fifth Amendment, plaintiff's initial hurdle is to establish that her interest in a within-grade pay increase was one protected by that clause. There being no suggestion that life or a liberty interest is involved, plaintiff can prevail only if that interest qualifies as “property.” There being no property interest in the historical sense of the term, she must show that the substantive provisions governing the grant of such increases give her a “legitimate claim of entitlement.”
Board of Regents of State Colleges v. Roth,
At the outset we reject plaintiff’s suggestion that the congressional and agency provision of grievance and arbitration
procedures
afford her a constitutional right, as she puts it, to use “established adjudicatory procedures to redress violations of law.” She rests the suggestion on a reference in
Logan v. Zimmerman Brush Co.,
Accordingly, we turn to the substantive standards of the statute and regulations, to see whether they afford the necessary “particularized standards or criteria [to] guide the ... decisionmakers.”
See Olim v. Wakinekona,
The controlling statutory language derives from the Federal Salary Reform Act of 1962, Pub.L. No. 87-793, 76 Stat. 832 (codified as amended in scattered sections of 5 U.S.C.) (1962). It replaces a system under which within-grade pay increases were tied to performance ratings of “satisfactory” or better, and provides that federal employees are advanced to the next highest rate of pay within a particular grade only if “the work of the employee ... is of an acceptable level of competence as determined by the head of the agency." 5 U.S.C. § 5335(a)(3)(B) (emphasis added).
The language conjures up a broad grant of discretion to the employee’s superiors. 4 The generality and subjectivity of the term “acceptable” indicates that Congress favored flexibility and discretion over rigid standards; its explicit vesting of the decision in the agency head further suggests that the measure of “acceptable” competence need not be an objective one.
The courts most expert in this field, examining the statute for purposes of ascertaining the scope of judicial review, have found it to grant the agencies relatively free rein. In
Creamer v. United States,
We start ... with the premise that the employing agency had considerable leeway in deciding whether an employee had reached and maintained “an acceptable level of competence.” This is indicated, first of all, by the words Congress used — “acceptable” necessarily implies discretion and choice; a judgment of “competence” plainly invokes evaluation, appraisal, and assessment; “as determined by the head of the [agency]” shows that no mechanical or automatic standard was being imposed by this statute, as had been the case under the prior law when a performance rating of “Satisfactory” was all-sufficient.
Id. at 416.
The court in Creamer went on to review the legislative history of the 1962 Act, finding most relevant an observation that Congress’s purpose throughout was to construct a pay system providing for “executive discretion to meet individual and special needs, to use pay for motivating employees, and to initiate general adjustments as required.” Id. (quoting Committee on Post Office and Civil Service, House of Representatives, Statement of Purpose and Justification and Section-by-Section Analysis of the Legislation Requested by the President of the United States to Reform the Major Federal Statutory Salary Systems 1 (Committee Print 1962)).
Other parts of the legislative history also support Creamer’s view. The Senate Report noted that “rigid statutory rules of pay administration [had] deprive[d] the [statutory pay] systems of the adaptability so essential in a period of rapidly changing conditions,” S.Rep. 2120, 87th Cong., 2d Sess. 4 (1962), and emphasized the need for “executive discretion to meet individual and special needs [and] to use pay for motivating employees ...,” id. at 3.
*497
Finding “a large grant of discretion” to the agency head,
The Court of Appeals for the Federal Circuit, the successor to the Court of Claims, S.Rep. 275, 97th Cong., 2d Sess. 3 (1982), U.S.Code Cong. & Admin.News 1982, p. 11, followed
Creamer
in analyzing the relation between agency discretion and the scope of judicial review of decisions under § 5335. In
Carroll v. Department of Health and Human Services,
The Senate Report also supported the proposed amendments with the argument that “the salary system must provide equity among Federal employees and between Federal employees and those in private employment.” S.Rep. 2120, 87th Cong., 2d Sess. 3 (1962). We do not take the reference to “equity” to undercut the stress on flexibility or in any way to endorse automatic, or semi-automatic, lockstep advances. Quite the opposite: the accompanying comparisons to private employment suggest that equity is to be secured by a broad discretion rather than by bureaucratic rigidity.
Civil service or IRS regulations might generate an entitlement where the statute had not,
Kizas v. Webster,
We must now decide whether such a standard — or lack of one — generates a property interest or entitlement. The cases do not delineate a line of crystalline purity, but we find several elements militating against a finding of a property interest: (1) the vagueness of the controlling term (“acceptable”), (2) Congress’s specific *498 vesting of the decisionmaking authority in the agency head, (3) the decision’s similarity to a promotion, and (4) Congress’s manifest interest in flexibility.
Vagueness of standard.
Obviously the term “acceptable,” standing alone, hardly amounts to “particularized standards or criteria.” In the context of
dismissal
of non-probationary employees, however, we have found some rather vague standards to be consistent with an entitlement. For instance, in
Johnson v. United States,
We note, however, that even in the context of
dismissal
for non-probationary employees, standards as vague as the present one are sometimes deemed to preclude the finding of an entitlement to continued employment. In
Drake v. Scott,
The vagueness of the criteria clearly militate against the finding of an entitlement; procedural safeguards are most valuable where an outcome may turn on the resolution of specific factual issues.
See, e.g., Mathews v. Eldridge,
Vesting decision and valuation in a specific party.
Such a vesting is often seen as compelling the conclusion that no property interest can be found. This has been true even in the context of dismissal itself, and even as to jobs not readily classifiable as “probationary.” In
Edwards v. Brown,
A number of other cases also stress the vesting of decisionmaking authority in a particular officer or office, but we put less weight on them because the character of the interest at stake bespeaks such a strong government interest in discretion. In this category are several cases involving employees with probationary status,
Dorr v. County of Butte,
Pay increase as promotion. A pay increase is of course a variety of promotion. As Congress recognized in the Federal Salary Reform Act of 1962, the superior’s flexibility in awarding such advancement is a useful tool in eliciting high-quality performance. See supra at 18-19. A within-grade pay increase under § 5335(a)(3)(B) is not aimed at protection of federal employees against inflation; that is covered by the pay comparability provisions of 5 U.S.C. § 5305 (1982), which were added in the Federal Pay Comparability Act of 1970, Pub.L. No. 91-656, 84 Stat. 1946 (codified in scattered sections of 5 U.S.C.) (1971). Nor is it an automatic seniority-based yearly pay hike; Congress’s express intent in the 1962 Federal Salary Reform Act was to replace just such a lockstep system with one based on a superior’s subjective evaluation of employee performance. See supra at 17. Rather, within-grade increases are the only method by which superiors can grant raises for good work or withhold raises for unacceptable performance to employees in certain grades; in those grades it is to perform the function that “merit pay” increases serve in the grades to which they are applicable.
In providing for merit pay in 1978 in the CSRA, 5 U.S.C. § 5401 et seq. (1982), 7 Congress gave off some conflicting signals as to the status of within-grade pay increases, but it changed neither the language nor, we think, the basic goal of flexibility. Congress provided that a “merit pay system” should apply to federal employees in higher grades, unless the employing agency secured a presidential exclusion from the system. 5 U.S.C. § 5401 (1982). But no employee can be covered by both: within-grade pay increases are not available for an employee covered by merit pay. 5 U.S. C. § 5335(e); S.Rep. No. 969, 95th Cong., 2d Sess. 91-92 (1978); H.R.Rep. No. 1403, *500 95th Cong., 2d Sess. 11 (1978), U.S.Code Cong. & Admin.News 1978, pp. 2723, 2813, 2814. Congress did not merely add the merit pay system on top of the existing within-grade increase scheme; that might have implied a congressional determination that the latter should operate primarily or entirely without regard to employee performance. Instead it made the two systems mutually exclusive, providing in each grade a single means for superiors to advance diligent employees.
To be sure, a portion of the legislative history of the CSRA in 1978 expressed discouragement as to fulfillment of the goals pursued by the 1962 act. The Senate Report on the CSRA decried the difficulty of “rewarding excellence and discouraging lackluster performance” under the then-current system, S.Rep. No. 969, 95th Cong., 2d Sess. 11 (1978), U.S.Code Cong. & Admin.News 1978, p. 2733, and noted that “[p]ay increases are awarded almost automatically,” id. Even assuming post-enactment legislative history could ever alter a provision’s original meaning, 8 we think these phrases cannot do so in the present context, where Congress’s acts manifested a steadfast attachment to the old purposes and simply installed a different mechanism for certain grades. We would hardly further Congress's intent if we used its discouragement about within-grade pay increases as a justification for further rigid-ifying the system.
Thus we find several elements supporting the classification of within-grade pay increases as promotions: Congress’s 1962 intent to give agencies a great deal of flexibility to reward superior performance; its 1978 decision to leave within-grade pay increases in place as the only method of granting performance-based pay raises to lower-grade federal employees; and the existence of a completely different system for inflation adjustment.
Courts have hardly ever found an entitlement to a promotion. Most relevantly, the Ninth Circuit has found no entitlement to merit pay increases — which, as we have seen, parallel within-grade increases.
Veit v. Heckler,
The one case finding an entitlement in the advancement context is
Needleman v. Bohlen,
The agreement in Needleman employed the same term as Congress supplanted in its adoption of the 1962 Act (or, strictly speaking, its inverse, “un satisfactory”). We do not claim any extraordinary or self-evident divide between “satisfactory” and “acceptable,” but Congress’s choice of the latter term, when it strove to confer greater flexibility on agency heads, may derive from a sense that “acceptability” tends inherently to conjure up the discretion of the person “accepting” the employee’s quality of performance. In any event, the Needle-man courts’ sketchy treatment of the subject disinclines us to accord their conclusion great weight. 9
Congressional concern for flexibility. This concern is manifest throughout. As noted, the vague language and the specific vesting of the discretion in employees’ superior officials point in that direction. So does the context — a variety of promotion. Congress’s references to the private sector carry the same connotation. It was concerned to attract and hold in the civil service the sort of people who respond to incentives, who are not drawn to a rigid system indifferent to talent or effort, who are ready to take chances. This intent seems to us to militate powerfully — perhaps conclusively — against classifying within-grade pay increases as entitlements. Cf. Note, Developments in the Law— Public Employment, 97 Harv.L.Rev. 1611, 1795-1800 (1984) (emphasizing need for flexibility in public employment decisions); Frug, Does the Constitution Prevent the Discharge of Civil Service Employees?, 124 U.Pa.L.Rev. 942, 989-996 (1976) (same).
IV. Conclusion
Congress in 5 U.S.C. § 7123 precluded review of appellant’s non-constitutional claims regarding the Authority’s decision. Although that language was not sufficiently precise under circuit law to cut off review of her constitutional claim, that claim fails because the congressional concern for flexibility in the awarding of within-grade pay increases is not consistent with finding a property interest in such mini-advancements. Accordingly, the district court’s order granting summary judgment is affirmed.
Notes
. Title VII of the CSRA is often referred to as the Federal Service Labor-Management Relations Statute ("FSLMRS”). To avoid the confusion that has permeated countless opinions and briefs, we will use the more general moniker "CSRA" throughout this opinion.
. Section 7122 authorizes FLRA review of exceptions to arbitral awards. It reads, in pertinent part:
(a) Either party to arbitration under this chapter may file with the Authority an exception to any arbitrator's award pursuant to the arbitration.... If upon review the Authority finds that the award is deficient—
(1) because it is contrary to any law, rule, or regulation; or
(2) on other grounds similar to those applied by federal courts in private sector labor-management relations;
the Authority may take such action and make such recommendations concerning the award as it considers necessary, consistent with applicable laws, rules, or regulations.

. Plaintiff makes no claim that agency conduct has, independently of the statute and regulations, created "mutually explicit understandings” that would form an entitlement,

. The discretion is not, however, so broad as to preclude judicial review of the merits of the IRS’s decision, which would have been available to Griffith if the arrangements between her union and the IRS had not supplanted her right of appeal to the Merit Systems Protection Board and thence to the Court of Appeals for the Federal Circuit.
See Espenshied v. Merits Systems Protection Board,
. The instant case concerns only those regulations. The current ones, which went into effect in March 1986, tie the determination of acceptable performance for within-grade increases into the existing agency performance appraisal systems, and thus may place somewhat greater constraints on the agency head’s discretion. 5 C.F.R. §§ 531.401-531.413 (1987).

In the text we merely considered (and rejected) a possible argument that the 1978 CSRA modified the correct interpretation of the 1962 act. A fortiori we would reject any suggestion that the CSRA so altered the "legal landscape” as to justify judicial revision of the 1962 act. See G. Calabresi, A Common Law for the Age of Statutes (1982) (proposing judicial revision of obsolete statutes); but see R. Posner, The Federal Courts: Crisis and Reform 290-92 (1985) (critical of the Calabresi proposal’s expansion of judicial power, its optimism about judicial capacity for assessing changes in legal context, and its disregard of interest-group character of some legislation); Weisberg, The Calabresian Judicial Artist: Statutes and the New Legal Process, 35 Stan.L.Rev. 213, 247, 256-57 (1983).
