Newport News Shipbuilding and Dry Dock Company (NNS) appeals from the March 4, 1991 decision of the Armed Services Board of Contract Appeals (the Board or ASBCA), ASBCA No. 33244, 91-2 BCA ¶ 23,865, 1991 WL 41865, reconsideration denied, 91-3 BCA V 24,132, 1991 WL 133263 (June 26, 1991), granting the government’s motion to dismiss NNS’ appeal for lack of subject matter jurisdiction. The ASBCA determined that NNS did not properly certify its claim to the contracting officer pursuant to Contract Disputes Act (CDA) section 6(c)(1), 41 U.S.C. § 605(c)(1) (1988), and its implementing regulation, Federal Acquisition Regulation (FAR) 33.207(e)(2), 48 C.F.R. § 33.207(c)(2) (1991). Because under the FAR, the NNS official who signed the certification was unqualified to do so, we affirm.
BACKGROUND
On January 21, 1986, NNS submitted a claim to the Navy’s contracting officer for “$8,414,054, which represents properly allowable and allocable contract costs arising out of the acquisition of NNS by Tenneco.... [And NNS claims] any and all unpaid monies that will accrue from the date of our calculation of the claim until this matter is resolved.” NNS’ Controller, Mr. John B. Bur-ling, Jr., certified the claim. . Upon the contracting officer’s inquiry info whether Mr. Burling was a proper certifier under the CDA, NNS’ Vice President of Finance, Mr. H.J. Lanese, replied that Mr. Burling “is authorized under the [CDA] to sign and certify any claims against the Government we may have. Mr. Burling is an elected officer of [NNS] having overall responsibility for the conduct of its affairs.” Subsequently, the contracting officer issued a final decision denying the claim. At the time Mr. Burling certified the claim, he reported to NNS’ Director of Finance who, in turn, reported to NNS’ Vice President of Finance. In particular, Mr. Burling testified:
[A]s controller, I had oversight over a wide spectrum of various accounting activities, virtually all of the accounting activities, for the company. I was 'responsible for the general accounting department, which maintained the official books and records of the company and recorded .all business transactions of the company.
I had responsibility for the financial reporting department which put together the company’s monthly and annual financial reports, its annual business plan, its five year business plan, reviewed and approved all capital[] expenditure requests, all major investments that the company would make.
At times, I had responsibility for the company’s internal budgeting and cost reporting, responsibilities of the accounts payable, the payroll department, the vendor analysis program, whereby we’d review sole source procurement from our suppliers.
... [A]ny branch of the government that would come in and review the companies’ [sic] accounting records, I was the primary focus for relationships with government .business personnel, government auditors.
I was responsible for negotiating any overhead settlements with the contracting officer, responding to all DCAA [Defense Contract Audit Agency] audit reports, reaching agreements with the contracting officer on accounting issues, preparing and working with the Tenneco people on putting together the home office overhead submittal, and responding to any audit reports that were issued by the Houston office! ] of the DCAA.
(Emphasis added.) Referring to the instant claim, Mr. Burling also testified that he “worked in the development of the claim and directed the people who worked for [him], in preparing the claim.”
An NNS letter to the Navy dated March 5, 1986 indicated that Mr. Burling had authority “to sign invoices pertaining to contracts with the Government.” However, neither the letter and an attached list nor an internal memorandum dated October 22, 1985 listed Mr. Burling among the numerous persons authorized to sign contractual documents on behalf of NNS.
*1550NSS subsequently appealed the contracting officer’s final decision to the Board which dismissed for lack of jurisdiction, ruling that under the FAR, Mr. Burling was not qualified to certify the claim. The only issues appealed to us are whether the FAR is lawful, whether court constructions of the FAR apply retroactively, and whether Mr. Burling met its requirements.
DISCUSSION
I.
Section 609(b) of title 41 defines our standard of review for decisions of agency boards of contract appeals as:
[T]he decision of the agency board on any question of law shall not be final or conclusive, but the decision on any question of fact shall be final and conclusive and shall not be set aside unless the decision is fraudulent, or arbitrary, or capricious, or so grossly erroneous as to necessarily imply bad faith, or if such decision is not supported by substantial evidence.
41 U.S.C. § 609(b) (1988). While we cannot disturb fact'findings supported by substantial evidence, Fruin-Colnon Corp. v. United States, 912 F.2d 1426, 1428 (Fed.Cir.1990), we review de novo the board’s conclusions of law, United States v. DeKonty Corp., 922 F.2d 826, 827 (Fed.Cir.1991). Whether or not the lower tribunal had jurisdiction is a question of law. Transamerica Ins. Corp. v. United States, 973 F.2d 1572, 1576 (Fed.Cir.1992). As discussed below, proper certification is a jurisdictional prerequisite and, therefore, who can qualify under the FAR to certify a claim is also a question of law. United States v. Grumman Aerospace Corp., 927 F.2d 575 (Fed.Cir.), cert. denied, — U.S. -, 112 S.Ct. 330, 116 L.Ed.2d 270 (Fed.Cir.1991). See also United States v. Boeing Co., 802 F.2d 1390, 1393 (Fed.Cir.1986) (“The interpretation of regulations which are incorporated into government contracts is a question of law which this court is free to resolve.”).
II.
In its briefs to this court and at oral argument, NNS urges the court to reverse or modify Grumman to the extent that it controls the disposition of this appeal. In effect, NSS, like the dissent, asks us to seek in banc treatment of this appeal. See Fed.Cir.R. 35(a).1 However, especially in light of the court’s formal refusal to rehear Grumman in banc, 927 F.2d at 581, and the long line of binding precedent Grumman followed, we determine that the instant appeal does not “require answer to a precedent-setting question of exceptional importance.” Fed.Cir.R. 35(a). Nor is there a conflict requiring in banc resolution. All of our ease law on the FAR is consistent with Grumman. Nor is there any Supreme Court decision in conflict with Grumman. Failing to find either threshold standard for hearing in banc, our panel is legally obligated to decide this appeal, applying the holding of Grumman as binding precedent. Newell Cos., Inc. v. Kenney Mfg. Co., 864 F.2d 757, 765 (Fed.Cir.1988) (“This court has adopted the rule that prior decisions of a panel of the court are binding precedent on subsequent panels unless and until overturned in banc.’’), cert. denied, 493 U.S. 814, 110 S.Ct. 62, 107 L.Ed.2d 30 (1989).
III.
Turning to the substance of the present appeal, NNS emphasizes that the CDA established a statutory basis for the subject matter jurisdiction of the ASBCA. Since in *1551NNS’ view, it satisfied the statutory requirements for ASBCA jurisdiction, the ASBCA cannot dismiss its appeal for lack of jurisdiction. To the extent that FAR 33.207(c)(2) imposes requirements not specified in the CDA, NNS reasons, the regulation improperly circumscribes the ASBCA’s statutory jurisdiction.
By assuming it met the statutory requirements for an appeal, NNS assumes the very issue we must decide. Moreover, NNS misstates the relationship between the CDA and FAR 33.207(c)(2). As we explained in Grumman, “[t]he statute, being silent on the question of the individual who may certify a claim for a non-individual contractor, leaves a gap.” 927 F.2d at 578. FAR 33.207(c)(2) “is entirely consistent with” CDA section 6(c)(1) and “merely serv[es] to fill the gap implicitly left by Congress respecting who may certify pursuant to that section.” Id. (emphasis in original). The regulation therefore does not im-permissibly limit statutorily defined Board jurisdiction. Rather, it is a part of that definition and implements the statute. See Ball, Ball & Brosamer, Inc. v. United States, 878 F.2d 1426, 1429 (Fed.Cir.1989) (“The [CDA] merely provides that ‘the contractor shall certify.’ The regulation constitutes a reasonable explication of how the ‘contractor’ shall certify, i.e., it identifies the individuals within the contractor’s organization who properly may act for the contractor in certifying.”). Even if NNS otherwise satisfied the statutory requirements for ASBCA jurisdiction then, NNS must still fulfill FAR 33,-207(c)(2) in order for the ASBCA to have jurisdiction under the CDA.
Nevertheless, NNS contends that Congress, in enacting the CDA, intended to eliminate agency power to “manipulate” ASBCA jurisdiction, and that FAR 33.207(c)(2) is antithetical to that objective. Applying the certification regulation, according to NSS, an agency “on the basis of its own interpretation of its own regulation, can challenge the subject matter jurisdiction of the forum that is adjudicating a contractor’s, claim against it.” Brief for Appellant at 17. Contrary to the overall legislative objective of the CDA, NNS asserts, consistent, prompt, and efficient resolution of contractor claims will thereby be jeopardized. NNS overstates its case. The certification regulation is not peculiar to claims arising under Naval contracts. Rather, it is a government-wide regulation. Contrary to NSS’ assertion then, the Navy is not interpreting “its own regulation.”
FAR 33.207(c)(2) is prescribed as part of a comprehensive federal procurement system. See 41 U.S.C. §§ 405 & 405a (1988) (directing the Office of Federal Procurement Policy (OFPP) to promote uniform procurement practice for executive agencies). See also 48 C.F.R. § 1.102(b) (1991) (“The FAR is prepared, issued, and maintained, and the FAR System is prescribed, jointly by the Secretary of Defense, the Administrator of General Services, and the Administrator, National Aeronautics and Space Administration-”).
NNS fails to point to, nor are we aware of, any Naval acquisition regulation implementing or supplementing FAR 33.207(c)(2) that conflicts with that FAR’s provisions. Therefore, the Navy plays no part in the jurisdictional definition. It is controlled solely by the FAR and the FAR is not malleable and hence subject to the alleged manipulation. Indeed, “[t]he regulation is unambiguous” and, therefore, must be applied “as written.” Ball, Ball & Brosamer, 878 F.2d at 1429. Moreover, NNS exaggerates the impact that a literal reading of the certification regulation may have in enabling manipulation of ASBCA jurisdiction. Indeed, a literal reading, because it is clear and hence the outcome is predictable, actually prevents manipulation by obligating the contracting officer and the contract board or Claims Court2 to accept all properly certified claims. Contractors, too, will .know whether their certifications are valid.
By requiring the certification of a high level or directly involved official, FAR 33.-207(c)(2) both protects the corporate contractor from potential liability for any fraudulent or inflated claims of less involved or lower level employees and deters submissions of *1552such claims. (“The certification requirement furthers an important objective of Congress by ‘trigger[ing] a contractor’s potential liability for a fraudulent claim under section 604 of [title 41],’ ... and thus ‘discouraging] the submission of unwarranted contractor claims.’ ”). Grumman, 927 F.2d at 579. As we indicated in Grumman, the certification requirement of the FAR strikes a reasonable balance among sometimes incongruent policy interests, and nothing in the CDA or the legislative history has been cited to us that directly or indirectly forbids it. 927 F.2d at 579. “In sum, the regulation being reasonable, this court may not substitute its own construction of the statutory provision on which it rests. Nor is the writing or amendment of regulations our proper role.... We are not privy to all of the agency’s reasons for its regulation and lack the expertise developed . over the years by the agency in dealing with all aspects of certification.” Id.
IV.
According to NNS, Congress did not authorize the government to promulgate binding regulations that could affect ASBCA subject matter jurisdiction.3 As a result, NNS argues, FAR 33.207(c)(2) is no more than an interpretative regulation, which does not bind courts. NNS further contends that the Navy’s contracting officer could and did waive the claim certification requirement by issuing a final decision in this case. NNS also asserts that the ASBCA effectively allowed the government to obtain recision of that final decision by securing dismissal of its appeal. Again, Grumman forecloses NNS’ arguments.
Despite NNS’ arguments to the contrary, the OFPP had statutory power to issue FAR 33.207(c)(2). Section 607(h) of title 41 generally authorizes and directs the OFPP, “as may be necessary or desirable to carry out the provisions of [the CDA], to issue guidelines with respect to criteria for the establishment, functions, and procedures of the agency boards....” 41 U.S.C. § 607(h) (1988). See 41 U.S.C. §§ 405 & 405a. On its face, FAR 33.207(c)(2), which fills the gap Congress implicitly left regarding who may certify under section 6(c)(1) of the CDA, “is clearly within the congressionally delegated authority of the” OFPP. Grumman, 927 F.2d at 578.4 Therefore, we must accord “considerable weight” to the agency’s interpretation of a statute it is responsible to implement. Chevron U.S.A. Inc. v. Natural Resources Defense Council, Inc., 467 U.S. 837, 844, 104 S.Ct. 2778, 2782, 81 L.Ed.2d 694 (1984).
NNS’ characterization of the regulation as merely interpretative is without merit. The contracting officer consequently could not waive the binding requirements of the regulation. Cf. Paul E. Lehman, Inc. v. United States, 673 F.2d 352, 356, 230 Ct.Cl. 11 (1982) (“The contracting officer ... had no’ authority to waive a requirement that Congress imposed.”). In addition, the contracting officer’s powers are specified by the CDA, and are limited. Waiving jurisdictional prerequisites is not among them.
In pressing its waiver argument, NNS also fails to come to grips with the extensive precedent holding that proper certification is a “jurisdictional prerequisite”.5 *1553See, e.g., United States v. Newport News Shipbuilding & Dry Dock Co., 933 F.2d 996, 998 (Fed.Cir.1991) (NNS I) (“Failure to comply with section 605(e)(1) ... and its implementing regulations deprives the Board of jurisdiction to hear the claim.”); Grumman, 927 F.2d at 579 (“It is well settled that the certification requirement is a jurisdictional prerequisite that must be satisfied by the contractor before it may appeal the contracting officer’s claim denial.”); Ball, Ball & Brosamer, 878 F.2d at 1428 (“Unless the contractor has submitted a properly certified claim to the contracting officer, there is no valid claim, the denial of which is an appeal-able decision of the contracting officer.”); Thoen v. United States, 765 F.2d 1110, 1116 (Fed.Cir.1985) (“Congress has determined that submission of a certified claim to. the contracting officer in the first instance is a jurisdictional prerequisite to filing a suit....”); Lehman, 673 F.2d at 355 (“Unless [the certification] requirement is met,' there is simply no claim that this court may review under the Act.”). Moreover, a party may challenge the subject matter jurisdiction of a federal tribunal at any time. See Bender v. Williamsport Area Sch. Dist., 475 U.S. 534, 541, 106 S.Ct. 1326, 1331, 89 L.Ed.2d 501 (1986) (restating that federal courts have limited jurisdiction); Phillips v. General Servs. Admin., 924 F.2d 1577, 1579 (Fed.Cir.1991) (“A jurisdictional matter can be raised at any stage of a judicial proceeding by any party or by the court on its own motion.”). Accordingly, the contracting officer could not waive the certification requirement by issuing a purportedly final decision and thereby create ASBCA jurisdiction despite the contractor’s noncompliance with section 6(e)(1) of the CDA and FAR 33.207(c)(2). In this regard, we agree with NNS that neither a contracting officer nor any other agency official can alter a board’s prescribed jurisdiction.
By assuming that the contracting officer has issued an appealable decision under the CDA, NNS ignores the premise for the conclusion that certification is a jurisdictional requirement. That is, although section 8(d) of the CDA directs a board “to decide any appeal from a decision of a contracting officer,” for claims more than $50,000, 41 U.S.C. § 607(d) (1988), a contracting officer may issue a decision only after “receipt of a submitted certified claim.” 41 U.S.C. § 605(c)(2) (1988). Absent appropriate certification, the contracting officer has no CDA claim on which to issue any decision. Ball, Ball & Brosamer, 878 F.2d at 1428 (“Unless the contractor has submitted a properly certified claim to the contracting officer, there is no valid claim, the denial of which is an appealable decision of the contracting officer.”); Lehman, 673 F.2d at 355 (“[U]nless a claim has been properly certified, it cannot be considered under the [CDA].”).6 There fore, the Navy contracting officer never rendered a decision appealable to the ASBCA because NNS had failed to properly certify its claim. There is therefore no valid contracting officer decision for the government to “rescind” or on which NNS could base its waiver argument.
To bolster the waiver argument, NNS points out that the contracting officer issued the purported final decision after requesting and receiving documentation from NNS concerning Mr. Burling’s qualifications to certify the claim. But whatever the contracting officer did or did not do, those actions cannot change Mr. Burling’s factual status within NNS, or its legal consequences under the FAR and the CDA. Moreover, the fact that NNS represented to the contracting officer that Mr. Burling was a proper official to certify under the CDA actually undercuts NNS’ waiver argument. In the words of *1554NNS’ Vice President of Finance, “Mr. J.B. Burling, Jr. is authorized under the [CDA] to sign and certify any claims against the Government we may have ... [and has] overall responsibility for the conduct of [NNS’] affairs.” Yet, it is undisputed he could only sign invoices, not contract documents. . Ironically, NNS now attempts to impute its own unfounded legal conclusions to the government when facts within its knowledge actual-. ly undercut those conclusions. NNS knew that Mr. Burling was not authorized to sign contract documents or even related documents, except for invoices. We cannot accept NNS’ waiver argument.
V.
NNS next challenges the ASBCA’s application of Grumman as an impermissible retroactive application of a new construction of FAR 33.207(c)(2). NNS reasons “that a 1991 interpretation of the regulation should have no bearing on the propriety of a 1986 certification.” Brief for Appellant at 30. Not only does NNS see Grumman as establishing a new interpretation of the FAR, but NNS also argues that retroactively applying Grumman would conflict with the purpose of the Grumman holding and produce gross inequities.
However, under the rule adopted by the Supreme Court in James B. Beam Distilling Co. v. Georgia, — U.S. -, 111 S.Ct. 2439, 115 L.Ed.2d 481 (1991), which defines the contours of Chevron Oil Co. v. Huson, 404 U.S. 97, 92 S.Ct. 349, 30 L.Ed.2d 296 (1971), NNS’ legal authority for its non-retroactivity argument, actually precludes NNS’ argument. NNS’ failure to discuss Beam in its opening brief is unfortunate. Its failure to cite Beam in its reply brief is inexplicable, since the government relies heavily on that case in its response brief. Even assuming, arguendo, that Chevron v. Huson permitted ad hoc court adjustments of ASBCA jurisdiction and that Grumman diverged from existing law, the Grumman court indisputably applied its construction of the terms of the FAR to the contractor before it. 927 F.2d at 580-81. This fact alone brings our inquiry to an end and defeats the retroactivity argument. Beam, — U.S. at -, 111 S.Ct. at 2446 (“[T]he question is whether it is error to refuse to apply a rule of federal law retroactively after the case announcing the rule has already done so. We hold that it is, principles of equality and stare decisis here prevailing over any claim based on a Chevron Oil analysis.”). Both the ASBCA and this court must apply the Grumman standards because those standards were applied to Grumman itself. Considerations of the purpose of the Grumman holding and equities are immaterial. Id. — U.S. at —, 111 S.Ct. at 2448 (“[W]hen the Court has applied a rule of law to the litigants in one case it must do so with respect to all others not barred by procedural requirements or res judicata.”). In any event, Grumman was hardly new; it merely followed Ball, Ball & Brosamer on the legality of the FAR requirement to apply it literally, and its jurisdictional effect.
VI.
Finally, NNS argues that Mr. Bur-ling actually met the requirements of FAR 33.207(c)(2) as interpreted in Grumman. Our precedent provides a clear guide in analogous facts to evaluate NNS’ compliance argument. In Ball, Ball & Brosamer, we determined that the contractor’s Chief Cost Engineer, whose authority and responsibilities were limited to the cost and claim aspects of contracts, did not meet either FAR standard because he was neither in charge of contract performance nor vested with overall responsibility for the: contractor’s affairs. 878 F.2d. at 1427. Similarly, Grumman’s Senior Vice President and Treasurer who “decid[ed] and reported] on whether particular dividend-like costs were employee compensation chargeable to a series of government contracts” was held not to be a proper certifying official under either prong of the FAR. Grumman, 927 F.2d at 580. Relying on Ball, Ball & Brosamer, we explained that an individual with overall responsibility just for a company’s financial affairs does not satisfy FAR 33.207(c)(2)(ii), which requires overall responsibility for the contractor’s af fairs generally. Grumman, 927 F.2d at 580. By contrast, however, we determined in NNS I that NNS’ sole Executive Vice Presi*1555dent, “directly under the Chairman and President and above other corporate ófficers and officials,” presumptively possessed such “overall responsibility.” 933 F.2d at 998 n. 2.
Insofar as NNS asserts Mr. Burling fits within the description of FAR 33.207(e)(2)(i), we are not persuaded because we cannot distinguish Mr. Burling from the officials in Ball, Ball & Brosamer and Grumman. Under the first prong of the regulation, a proper certifier would be “[a], senior company official in charge at the contractor’s plant or location involved.” 48 C.F.R. § 33.-207(c)(2)(i). This “description demands that the certifying senior company official have both primary responsibility for the execution of the contract and a physical presence at the location of the primary contract activity.” Grumman, 927 F.2d at 580 (emphasis in original).
The record7 contains absolutely no evidence that Mr. Burling had “primary responsibility” for contract performance. In fact, Mr. Burling as company controller only “had oversight over a wide spectrum of various accounting activities.”' That an affidavit asserted he was “vested with unrestricted authority to certify and submit [NNS’] 'claim to the Contracting Officer” is insufficient to establish primary responsibility for contract performance. See Ball, Ball & Brosamer, 878 F.2d at 1428 (finding authorization to sign and certify claims, by itself, inadequate). Moreover, the record does not indicate that Mr. Burling had any physical presence at the primary location for contract performance as specifically required by Grumman. 927 F.2d at 580. In this regard, Mr. Burling is identical to the Grumman official. See 927 F.2d at 580. NNS’ evidence which shows that Mr. Burling was in charge of and located at the accounting department at NNS headquarters, but does not also show that the accounting department was the primary location of contract activity, is inadequate. Obviously, Mr. Burling was not present at the shipbuilding slip. Notwithstanding that the claim may involve accounting issues, those issues are incidental to an underlying contract with the government. Given that the purpose of FAR 33.207(c)(2) is' to assure that only knowledgeable, accountable and responsible corporate officials submit claims, the regulation reasonably identifies the relevant situs as the place where the contract is primarily executed. Substantial evidence supports the ASBCA’s determination that Mr. Burling did not satisfy FAR 33.207(c)(2)(i), and the determination is neither arbitrary nor capricious nor. tainted with fraud or bad faith. To the extent it is derivative of factual findings, all of them are supported by substantial evidence. As a legal conclusion, it is not erroneous.
Alternatively, “[a]n officer or general partner of the contractor having overall responsibility for the conduct of the contractor’s affairs” would also be a proper certifier for a CDA claim. 48 C.F.R. § 33.207(c)(2)(ii). By the plain language of the regulation, the person must have responsibility of general scope. Grumman, 927 F.2d at 580. We find the ASBCA’s determination that Mr. Burling did not have such “overall” authority within NNS is legally correct and rests on substantial evidence. Much like the facts of Ball, Ball & Brosamer and Grumman, Mr. Burling’s own testimony details responsibility limited solely to various accounting and financial matters. In contrast to the NNS I Executive Vice President, Mr. Burling, the company controller, had no apparent overall authority or responsibility. Indeed, NNS’ March 5, 1986 letter to the Navy and attached list and the NNS internal memorandum of October 22, 1985 indicate Mr. Burling may not even sign contracts or contract-related documents on behalf of NNS, but may only “sign invoices pertaining to contracts.” Invoices do not involve disputed monies; claims do. Therefore, Mr. Burling’s specified actual authority was limited both in breadth and height — surely inconsistent with overall responsibility.
In the face of this substantial evidence, NNS merely stresses ’that Mr. Bur-*1556ling was an elected corporate official, yet fails to discuss the record detailing what Mr. Bur-ling could do and not do and how the ASBCA reversibly erred in view of all the evidence. An elected corporate officer does not automatically qualify as a proper certifying official under FAR 33.207(e)(2)(ii). All corporate officers do not necessarily have “overall” authority for the corporation’s affairs. The regulation requires us to look beyond official titles and to the breadth of the certifier’s responsibilities. Similarly, we must look behind conclusory and self-serving post-certification assertions made by-the contractor only when challenged, as here, that the individual has “overall responsibility for the conduct of the contractor’s affairs.” As in Ball, Ball & Brosamer and Grumman, the duties of the certifying official here plainly were limited, not general. Mr. Burling was responsible only for financial and accounting matters, and even then was three levels down from the top financial official.8 Those limited duties belie the naked assertion of overall responsibility. In light of the evidence, we cannot say the ASBCA’s determination that Mr. Burling did not satisfy FAR 33.-207(e)(2)(ii) is arbitrary or capricious, shows fraud or bad faith, or is unsupported by substantial evidence.9 Nor, in light of the holding of Grumman, can we say that in discerning or applying the FAR standards, the Board committed legal error.
THE DISSENT
I. Rule 35 Standards for In Banc Review
The dissent asserts that this case should be taken in banc to reevaluate Grumman because “circumstances have changed dramatically [since the court’s refusal in 1991 to rehear Grumman in banc ] as a result of Grumman’s many adverse effects on government contracting practice.” Dissent, at 1565. In support of its position, the dissenting opinion repeats at great length many “reactions by the bench, the bar and the administrative community in opposition to Grumman and the efforts to vitiate its stultifying effects on Federal Government procurement.” Id. at 1565. The dissent concludes that Grumman “should be revisited in light of the growing amount of criticism leveled at it and the successful legislative and pending regulatory efforts to circumvent it.” Id. at 1565.
Conspicuously missing from the lengthy dissenting opinion, however, is any independent legal analysis of why, in light of regulatory and statutory language and legislative history, Grumman was wrongly decided or how its rationale that the FAR is a reasonable (“permissible”) interpretation of the CDA deserving deference under Chevron is fatally flawed. While .such a showing, even assuming it could be made, might justify revisiting Grumman in banc, the alleged “many adverse effects on government contracting practice,” id., do not. Nor do “the growing amount of criticism” or legislative and regulatory revision efforts. Revisiting Grumman on the basis of the public criticism repeated uncritically by the dissent would substantially deviate from the only two bases allowed by Fed.Cir.R. 35 and would establish a new standard for, in banc review, ie., if *1557enough industry, bar or academic commentators complain vociferously enough about a panel decision, on that basis alone we will rehear the issue in banc.
The dissent implies that this case requires an answer to a question of exceptional importance, citing Fed.Cir.R. 35. Id. at 1573. First, the dissent omits half the explicit requirement of Fed.Cir.R. 35. In addition to being of exceptional importance, the question must be “precedent-setting.” But here the precedent had already been set in Ball, Ball & Brosamer, two years earlier, and in even earlier cases of both the Federal Circuit and one of its predecessor courts, the Court of Claims.10 Nor is there a conflict, the only other authorized basis for in banc rehearing, between Grumman and other panel decisions of our circuit or the Supreme Court. On the contrary, every other Federal Circuit panel that either before or after Grumman has reviewed the FAR has, like the Grumman panel: (1) upheld it as lawful, (2) found it jurisdictional,11 and (3) applied it literally. See, e.g., Kiewit/Tulsa-Houston v. United States, 981 F.2d 531 (Fed.Cir.1992); NNS I, 933 F.2d 996; Universal Canvas, Inc. v. Stone, 975 F.2d 847 (Fed.Cir.1992); Ball, Ball & Brosamer, 878 F.2d 1426. That is all we do today. Nor has the Supreme Court ever treated the Grumman issue. In fact, the closest it ever came was in denying certiorari in Grumman itself.
No precedent-setting question is answered herein. Nor does our decision conflict with any binding precedent. Thus, in banc review would violate our rule. Therefore, as a panel we have no basis to request it.
Moreover, the court’s decision in Grumman in 1991 did not create the effects decried by the dissent, as it implies. Rather the FAR itself created" the problems when in 1980 it was written more narrowly than necessary or perhaps wise. See 32 C.F.R. § 1.314 (1981) (referencing promulgation date of Aug. 24, 1980) (redesignated at 50 Fed.Reg. 2270 (Jan, 15, 1985) as 48 C.F.R. § 33.207). That the regulation could have been drafted differently (and more wisely) does not make it invalid under a Chevron analysis as unreasonable or impermissible in light of the statute it implements and the legislative history. Only conflict with the statute it implements or clearly expressed legislative intent could make the FAR unreasonable under Chevron.
Grumman, like Ball, Ball & Brosamer, merely applied the plain meaning of the FAR after upholding it as a reasonable interpretaion of the CDA. The regulation “merely ... flll[s] the gap implicitly left by Congress respecting who may certify pursuant to [the, CDA].” Grumman, 927 F.2d at 578. In such a case, i.e., where “the legislative delegation to an agency on a particular question is implicit rather than explicit[,] ... a court may not substitute its own construction of a statutory provision for a reasonable interpretation made by the administrator of an agency.” Chevron, 467 U.S. at 844, 104 S.Ct. at 2782 (emphasis added). The. regulation must be deémed a “permissible construction of the statute,” id. at 843, 104 S.Ct. at 2782, and reasonable if it is not “contrary to clear congressional intent.” Id. at 843 n. 9, 104 *1558S.Ct. at 2781 n. 9. See Pauley v. Bethenergy Mines, Inc., — U.S. -, -, 111 S.Ct. 2524, 2536, 115 L.Ed.2d 604 (1991) (determining reasonableness of agency’s interpretation of its own regulation by considering congressional intent). Thus, as our court itself has recognized, the regulator’s implementation of the statute must be upheld unless it “ ‘contravenes clearly discernible legislative intent’ or is otherwise unreasonable.” True v. Office of Personnel Management, 926 F.2d 1151, 1155 (Fed.Cir.1991) (quoting Beneficial Corp. v. United States, 814 F.2d 1570, 1574 (Fed.Cir.1987) (quoting American Lamb Co. v. United States, 785 F.2d 994, 1001 (Fed.Cir.1986))).
Thus, the Grumman court had, and we have, no authority to second guess the drafters of the FAR so long as the FAR is deemed reasonable. As explained below, the FAR is not inconsistent with expressed congressional intent, but instead properly implements congressional intent by specifying who may certify a claim, and does so in a way that promotes primary statutory goals: liability for civil fraud and deterrence of filing of inflated claims. As stated in Grumman, “the regulation is not unreasonable, and ... it is in furtherance of congressional objectives....” 927 F.2d at 579. As such, the FAR and the statute are what need to be revisited, not Ball, Ball & Brosamer or Grumman or the earlier precedent of this court or the Court of Claims.12 Fortunately, the FAR and the statute have now been amended, as the law requires, by their makers, not this court. This court is empowered to rewrite neither statutes nor regulations, however un-wise, nor does it have the information base nor expertise to do so effectively-
II. Deficiencies in Criticisms Cited by the Dissent
We are reluctant to repeat all the heated criticisms by others which are quoted so extensively and repetitively in the dissent, lest the reader assume thereby that we agree they have arguable legal or interpretive, as opposed to political or policy, merit, or are at all relevant to whether the holding of Ball, Ball & Brosamer and Grumman and their many predecessors may and should now be overruled in banc. However, we cannot fail to point out that many of the criticisms of Grumman are entirely unsupported and unsupportable.
A. Litigation statistics. The dissent recites ASBCA statistics for 1991 as evidence of a sudden and dramatic post-Grumman increase in litigation over who may certify claims on behalf of corporate contractors. But no comparable figures are given for pre-Grumman years. Therefore, the inference of a sharp increase caused by Grumman is hardly established. Nor is it clear whether any increase was caused by Grumman in 1991 as compared to Ball, Ball & Brosamer in 1989.
Besides, the volume of cases which discuss certification is probative only of the number of times the government has moved to dismiss appeals on that basis. That the plain language of the 1980 FAR raises a serious issue in so many cases certainly cannot establish that Ball, Ball & Brosamer and Grumman were wrong or that the FAR is unreasonable. It may prove only how often contractors ignored the plain and specific terms of the FAR, although it was promulgated in 1980 and not changed for 13 years. Indeed, how a 1980 FAR can be said in 1991 to have created “a trap for the unwary,” as asserted in the dissent, is difficult to follow. In any event, even assuming a sharp rise in cases raising the certifier issue, that fact could not establish that the Ball, Ball & Brosamer-Grwmman constructions of the FAR themselves conflict with the CDA.
*1559B. Purposes of the CDA and the certification requirement. The dissent argues nonetheless that, per the critics, litigation over this issue “accomplishes nothing but delaying the fair consideration of the contractors’ claims, a result contrary to the fundamental purpose of the CDA which is to provide fair and expeditious resolution of Government disputes.” Dissent, at 1567 (emphasis added). This statement may be somewhat unclear or misleading in two respects. ■ First, as to what litigation “accomplishes,” the answer is compliance with the command of Congress, i.e., enforcement of the statute, as written, as explained below. Second, although litigation over the certification requirement may in some cases push back the date from which various contractors are entitled to interest on their recertified claims if they prevail, contrary to the dissent, it does not necessarily or routinely prevent and need not substantially delay consideration of the merits of the claims themselves.13 Finally, there is no necessary connection between “fair” resolution of the claim and the existence or non-existence of an issue concerning jurisdiction and certification. In any event, if the contractor had followed the plain and specific if narrow terms of the 1980 FAR, no delay at all could have followed. No one should have needed Ball, Ball & Brosamer in 1989 or Grumman in 1991 to know so.
Moreover, while the expeditious resolution of contract disputes is indeed one of the purposes of the CDA, it is plainly not the ohly purpose. The CDA, and in particular the certification requirement of section 605, serves other preeminent purposes as well. Congress expressly indicated that certification would serve to bind the contractor under civil fraud statutes as well as under contract law. S.Rep. No. 1118, 95th Cong.2d Sess. 7-8 (1978), reprinted in 1978 U.S.C.C.A.N. 5235, 5241-42 (hereinafter “Senate Report”). As we observed before, the “regulation properly implements this objective by specifying the persons in the contractor’s organization who may certify a claim.” Grumman, 927 F.2d at 579 (quoting Ball, Ball & Brosamer, 878 F.2d at 1429) (emphasis omitted). Thus, the certification requirement of the FAR furthers other important goals of the CDA and particularly of section 605 itself. As the specific substantive section in issue here, its purposes, clearly illuminated by legislative history, surely trump other general goals of the overall statute to the extent they are arguably inconsistent, particularly where the general goals are stated only in general, introductory and hortatory language, as they are here.
Congress was very clear about the purpose of certification. In a section of its report entitled, “Discouraging the unwarranted submission of contractor claims,” the Senate Committee said that, according to Navy witnesses, a “substantial number of these outstanding claims were greatly inflated.” Senate Report at 8, reprinted in 1978 U.S.C.C.A.N. at 5242. The Committee then noted: “In fact, some have been turned over to the Justice Department for investigation of fraud.” Id. (emphasis added). It then said: “Section 4(b) of the act is designed to specifically address the inflated claim problem by assigning stiff penalties to contractors who engage in such practice.” Id. (emphasis added). The “penalties” referred to are for civil fraud, including under the False Claims Act, 31 U.S.C. § 231 et seq., which is specifically mentioned in the Committee Report. Id. at 20, reprinted in 1978 U.S.C.C.A.N. at 5254. In addition, section 4(b) itself authorizes the government to- sue contractors for fraud, creating a cause of action in addition to those created by, for example, the False Claims Act. Hence, it is beyond serious argument that Congress intended the CDA to deter and redress fraud. Indeed, this court recently restated our precedent that the certification requirement as implemented by the FAR fosters that intent:’ “The requirement goes to the very ‘integrity of the federal procurement system and the public fisc,’ Universal Canvas, Inc. v. Stone, 975 F.2d 847, 850 (Fed.Cir.1992), by ‘triggering a contractor’s potential liability for a fraudulent claim under section 604 of the Act and thus discouraging the submission of un*1560warranted contractor claims, Ball, Ball & Brosamer, 878 F.2d at 1429 (quotations, alterations, and citations omitted).” Kiewit, 981 F.2d at 533.
The Committee Report also references Admiral Hyman Rickover’s testimony before two Senate subcommittees. Before the subcommittees Admiral Rickover stated that the CDA should require “the contractor [to] submit to the Government a certificate signed by a senior responsible contractor official, which states that the claim and its supporting data are current, complete and accurate.” Contract Disputes Act of 1978: Joint Hearings on S. 2292, S. 2787, and S. 3178, Before the Subcomm. on Federal Spending Practices and' Open Government of the Senate Comm, on Governmental Affairs and the Subcomm. on Citizens and Shareholders Rights and Remedies of the Senate Comm, on the Judiciary, 95th Cong., 2d Sess. 21 (1978) (hereinafter “Joint Hearings ”) (emphasis added).
Lower-level officials, although often able to bind their corporation in contract, could not bind it in fraud in the context, for example, of large shipbuilding or other defense firms. Yet firms with these very contracts were the ones concerning which Congress expressly wanted to deter inflated or fraudulent claims. By appointing a lower-level official to certify claims, a contractor could seek to escape liability for fraud. The congressionally desired deterrence would then fail. Clearly, deterrence can only work if the certifier is senior enough or, if less senior, is directly involved enough in contract performance to make the corporation itself liable for any fraud.
Congress intended not only deterrence but also liability. Hence, the Senate Report includes a discussion of “stiff penalties” and the Committee’s assertion that under section 4(b) a fraudulent contractor “shall be liable to the Government.” Senate Report at 19, reprinted in 1978 U.S.C.C.A.N. at 5253. Indeed, our precedent has long recognized that Congress saw both deference and liability as important. See Skelly & Loy v. United States, 685 F.2d 414, 418 n. 11, 231 Ct.Cl. 370 (Ct.Cl.1982) (stating that the certification requirement “triggers a contractor’s potential liability for a fraudulent claim under section 604 of the Act”); Folk Constr. Co. v. United States, Ct.Cl. No. 99-80C, 1981 WL 21438 (order entered Jan. 16, 1981) (stating that “[t]he purposes of the certification requirement are to discourage the submission of unwarranted contractor claims and to encourage settlement”). Again, neither deterrence nor liability can work very well if a contractor is permitted to have lower-level or less directly involved officials certify claims. That is precisely what the FAR precluded. That it may have gone further than necessary does not destroy its efficacy to accomplish these congressional purposes.
Moreover, the Admiral’s emphasis on “a senior responsible contractor official” implies far more than simply that the certifier have personal knowledge of all the details, which the dissent implies was Admiral Rickover’s sole concern. Indeed, most of the Admiral’s testimony concerned contractor fraud against the government. He analogized contractor certification to taxpayer certification. In both cases, a senior official must sign if the corporation is to be held accountable and subject to “stiff’ civil penalties. No • one would reasonably argue that any mid-level official who can execute a small contract for routine supplies for a big defense contractor can also sign its corporate federal tax returns and thereby expose it to civil liability for tax fraud. Yet the dissent cites the Admiral’s analogy to signing tax returns as if it supported the dissent’s assertion. It does not. On the contrary, it supports the FAR requirements of higher level or more involved officials.
After testifying at length about the fraud problem, “Admiral Rickover ... submitted written suggestions for amending the Act, which were reprinted.in the report of the hearings in the middle of his testimony and which were substantially similar to the actual language of sections 6(c)(1) and (2).” Lehman, 673 F.2d at 355. One of the Admiral’s written suggestions was that the bill be amended, as it was, to provide that:
For claims of more than $50,000, the contractor shall certify that the claim and supporting data are current, complete and accurate when the claim is submitted, and *1561also certify that the conclusion in the claim accurately reflects the contract adjustment for which the contractor believes the Government is liable.
Joint Hearings at 13. We have previously construed his intent:
Admiral Rickover wanted to deter contractors from filing inflated claims which cost the government substantial amounts to defeat. He sought to do so by subjecting contractors to financial- risk if their claims were unreasonable.... Admiral Rickover viewed the certification requirement as a necessary prerequisite to the consideration of any claim. The provisions Congress adopted to include the certification requirement were based upon Admiral Riekover’s written suggestions and fairly must be deemed to have incorporated his view concerning the effect of the certification requirement.
Lehman, 678 F.2d at 355 (emphasis added).
As discussed above and as prior decisions such as Lehman and Ball, Ball & Brosamer have noted, the legislative history conclusively establishes that fraudulent claims were at the core of Rickover’s and Congress’ concerns. As we noted, requiring a high-level official to sign the certification would deter fraud because by his signature such officer would expose the corporation to potential liability under civil fraud statutes. Rickover’s concerns were the paramount motivation for the addition to the CDA of the certification requirement by amendment on the Senate floor on the day of its passage. See 124 Cong.Rec. 36,267 (1978) (Senator Byrd, sponsor of the amendment, stated that section 5(c) of the Act, which includes the certification requirement, “has been amended due to the concerns expressed by ... Admiral Rickover.... ”). His concern is plainly well met by the FAR which requires certification for corporations by higher-level or more directly involved officials rather than merely any employee with authority to bind the corporation in contract. The FAR does no more than demand Admiral Rickover’s “senior responsible contractor official.” Implementing the statute, it does no more than make proper certification, in Admiral 'Rickover’s words, a “necessary prerequisite to the consideration of any claim.” Lehman, 673 F.2d at 355. It is therefore entirely consistent with the legislative history that illuminates congressional intent in adding the certification requirement. As such, the FAR is a reasonable construction of section 605 within the meaning of Chevron. Therefore, we are required to accept it without regard to the possibility it could have been written to include more officials while still achieving the congressional purposes.
III. Certification as a Jurisdictional Prerequisite
A. Long-established and uniform precedent. The focus of the dissent’s challenge to the rationale of the 10-year line of eases it lumps with Grumman is its assertion that the certification requirement should never have been deemed a jurisdictional prerequisite. If Grumman’s restatement of established and binding precedent that the certification requirement is jurisdictional were to be altered, however, much more than just Grumman would have to be overruled. Grumman merely followed the unbroken line of our precedent going back 10 years that so held; at considerable cost to stare decisis, all of these eases would have to be overruled too. In recent times, the cases include Kiew-it, Universal Canvas, and Ball, Ball & Bro-samer. The earlier cases were listed in Grumman:
Thoen v. United States, 765 F.2d 1110, 1116 (Fed.Cir.1985) (“Congress has determined that submission of a certified claim to the contracting officer in the first instance is a jurisdictional prerequisite....”); W.M. Schlosser Co. [v. United States], 705 F.2d [1336] at 1338 [ (Fed.Cir.1983)] (“Unless the claim was certified when it was submitted to the contracting officer, the Board should have neither heard nor ruled on the appeal.”); Milmark Servs., Inc. v. United States, 231 Ct.Cl. 954, 956 (1982) (“It is well established that without such a formal claim and final decision by the contracting officer, there can be no appeal to this court under the CDA. It is a jurisdictional requirement. ”); W.H. Moseley Co. v. United States, 677 F.2d 850, 852, 230 Ct.Cl. 405 (“Since plain*1562tiff failed to certify its claim as required by section 6(e)(1) of the Contract Disputes Act of 1978, we are without jurisdiction to consider its direct appeal to this court.”), cert. denied, 459 U.S. 836, 103 S.Ct. 81, 74 L.Ed.2d 77 (1982); Paul E. Lehman, Inc. v. United States, 673 F.2d 352, 355, 230 Ct.Cl. 11 (1982) (“Unless [the certification] requirement is met, there is simply no claim that this court may review under the Act.”).
Grumman, 927 F.2d at 579 (emphasis added).
Rather than argue the merits of why, under particular language of the statute or legislative history, the certification requirement should not be deemed a jurisdictional prerequisite, the dissent merely challenges the lack of analysis in some of the later cases. Echoing industry critics, the dissent states: “[T]he cases that have considered the issue simply cite to earlier decisions with little or no analysis of their own.” Dissent, at 1568. Only one example, Lehman, however, is given by the dissent. But Lehman, decided in 1982, is not one of the later cases citing to earlier decisions, but one of the earliest decisions. Id. Second, relying on a brief of the National Security Industrial Association (NSIA), the dissent states that “Lehman never discusses the issue of jurisdiction.” Id. While it is true that Lehman never uses the word “jurisdiction” in connection with the certification requirement, it is not accurate to say that Lehman never treats jurisdiction. After a page and a half discussion of the statutory language and the legislative history of the certification requirement, Lehman concludes:
The import of the language of the Act and its legislative history is that unless a claim has been properly certified, it cannot be considered under the statute. As we said in Folk, “The statute thus requires that to be valid a claim must be properly certified.” Unless that requirement is met, there is simply no claim that this court may review under the Act.
673 F.2d at 355 (emphasis added). Not only does this statement plainly concern jurisdiction, but the page and a half discussion leading to this conclusion certainly qualifies as a discussion and analysis of the jurisdictional issue. In any event, while the lack of a complete analysis in some of the later cases may be frustrating and may require the reader to refer to the earlier cases, it hardly renders the court’s continuing conclusion in all of these cases erroneous. Indeed, the implication of stare decisis is that settled issues need not be reanalyzed in every successive case.
B. Legislative history. The dissent quotes attorney argument that the jurisdictional nature of the certification requirement “runs directly afoul of the express intent of Congress to divest the agencies of their previous power to define the jurisdiction of the boards through disputes clause requirements and regulations.” Dissent, at 1568 (emphasis added). First, the FAR is not promulgated by the “agency,” here the Navy, but by a government-wide procurement authority, OFPP, specially mandated by Congress itself to implement the CDA. Second, the dissent cites no supporting statutory language or legislative history.
Simply put, there is nothing in the legislative history indicating error in the Federal Circuit and Court of Claims’ continuing conclusion for more than 10 years that the certification requirement is jurisdictional. In fact, the dissent quotes a portion of the legislative history that suggests quite the contrary. As the dissent noted, Admiral Rickover testified that the Act should require “as a matter of law that prior to evaluation of any claim, the contractor must submit to the Government a certificate signed by a senior responsible contractor official.” Id. at 1565 - 66 (emphasis altered). Certainly, that portion of the legislative history supports the conclusion that the certification requirement was intended to be jurisdictional, not the dissent’s express view that Admiral Rickover did not view certification as jurisdictional.
C. The statute. Indeed, the statutory language of the CDA itself strongly suggests the same conclusion. As analyzed in Lehman, 673 F.2d at 354, the contracting officer’s statutory authority (and obligation) to issue a decision arises only after the officer has received a “certified claim,” 41 U.S.C. § 605(e)(2). And the right to appeal to an agency board of contract appeals, or to file *1563suit in the Claims Court is, in turn, expressly conditioned by the Act itself upon the “receipt of a contracting officer’s decision under section 605, ” 41 U.S.C. § 606 (emphasis added). Thus, taken together these two provisions of the statute practically compel the conclusion that the certification requirement was indeed meant to be jurisdictional. This conclusion is all the clearer when one considers that unlike courts which have inherent judicial power under article III of the Constitution, contract boards have only the limited authority expressly granted by statute. Lehman ’s conclusion, quoted above, is therefore not only legally sound but also logically required. See also Skelly & Loy, 686 F.2d at 418 (stating that “[sjinee the Act specifies that certification is to take place in the first instance — on submission of a claim to the contracting officer — a contractor who did not so certify would not only be barred from the direct access route [of judicial review], but from the board route as well” (emphasis added)). Obviously, the bar arises from the fact that certification is, per section 606, jurisdictional.
D. Effect of jurisdictional nature of certification requirement. The dissent concludes by suggesting that the Grumman panel overstepped proper bounds in deciding the jurisdictional issue in that case because the case could and should have been dismissed merely for failure to state a claim upon which relief could be granted. That suggestion represents a fundamental misstatement of the rules of precedence governing issues of jurisdiction. Before a court may determine whether a claimant has stated a claim upon which relief can be granted, it must first determine whether it has jurisdiction to make any determination over the particular dispute. If not, it is without authority to determine whether the claimant has adequately stated its claim, or to make any other determination. Thus, the dissent’s characterization of Grumman’s discussion of jurisdiction as mere “dicta” is unfounded. Dissent, at 1573. Moreover, the authorities that require deciding jurisdiction before the sufficiency of the complaint are so long, and well and clearly established as to require no citation.
The dissent also repeats concerns expressed by the Shipbuilders Council over the possibility of last-minute government manipulation: “[F]irst, the agency through its contracting officer, permits the appeal to be filed by issuing a final decision, but then later, through its litigation counsel, contests the validity of the certification by a post hoc reapplication of the regulation and demands dismissal.” Dissent, at 1568 (emphasis added). The dissent asserts that “this is the exact circumstance that occurred with Newport.” Id. , The issue raised by the Council’s concerns, however, cannot be dispositive, for any implication of bad faith is unjustified on the undisputed facts. Of course, the contracting officer is not a lawyer. Moreover, both agency counsel and Justice Department attorneys have an affirmative duty to raise jurisdictional issues. As this court recently said in yet another application of Grumman and Ball, Ball & Brosamer, “All participants have a duty to assure there are no jurisdictional impediments at the earliest possible stage.” Universal Canvas, 975 F.2d at 850. Justice Department and agency counsel, of course, do not enter the case until after the complaint is filed in the Claims Court. Similarly, until an appeal is filed before a contract board, litigation counsel from the agency are not involved. Thus, they have no earlier opportunity than the appeal to a contract board or the filing of a Claims Court suit to litigate this issue. Therefore, the dissent’s reference to “the agency” and “its counsel” is inaccurate.
IV. The FAR Reasonably Interprets Sections 605-06 of the CD A and the Meaning of the FAR Is Plain
Furthermore, as we observed in Grumman, our court is not the regulator. In interpreting a regulation, the court must look to the language of the regulation and the language and legislative history of the statute which the regulation implements. That is explicitly what was done in Ball, Ball & Brosamer and in Grumman. As long as the regulation is a reasonable one, not necessarily the only or the most reasonable one, it warrants Chevron deference. Controlled by earlier decisions, the Grumman court again *1564held it was reasonable. And, if the new regulation discussed in detail in the dissent is wiser and more practical than what it replaces, that does not establish that its predecessor was unreasonable.
Finally, in arguing that the FAR is unreasonable, the dissent quotes the July 22, 1991 issue of the Federal Contracts Report as stating that the FAR “effectively precluded] all but those 'at the CEO level” from certifying claims. Dissent, at 1571. This statement entirely ignores the first prong of the FAR, which allows “[a] senior company official in charge at the contractor’s plant or location involved” to certify claims. In Grumman, this court expressly considered whether the FAR is a “CEO Only” rule and concluded that it is not. “[C]ertification by a CEO is not required by the regulation or by anything said in either of this court’s opinions in this case. Indeed, any such requirement would read the first [prong] completely out of the regulation.” 927 F.2d at 581. Moreover, our subsequent case law also shows that the FAR is not a “CEO Only” or CEO and equivalent rule. See, e.g., Ingalls Shipbuilding, Inc. v. O’Keefe, 986 F.2d 486 (Fed.Cir.1993) (allowing certification by Ingalls’ Vice President of Administration).
At this point, Congress has amended the law so that the certification requirement can be met after filing in the board or Claims Court, but proper certification is still required before the claim may be adjudicated. Court of Federal Claims Technical and Procedural Improvements Act of 1992, Pub.L. No. 102-572, § 907, 106 Stat. 4516, 4518-19. The dissent simply presumes that by amending the statute Congress simply made express what it had always intended and thereby “corrected” an error by this court. Such presumptions, however, are not warranted. Rather, the congressional action simply shows that the elements of the bar and industry were successful in lobbying Congress to change a law which they found inconvenient. Moreover, that the 1992 amendments are expressly made prospective only hardly supports the contention that in 1978 Congress had not intended the CDA certification requirement to be jurisdictional. Finally,' that Congress did not change the operative language, but simply mandated in 1992 that henceforth the certification requirement of the 1978 CDA shall no longer be considered jurisdictional as of the date of filing does not establish that the original language was not intended by the enacting Congress to be jurisdictional as of that date, as our precedent holds.
Additionally, the amended FAR has, or will soon become effective. Thus, the regulator has acted by broadening those who may certify to include any official designated in writing by the Board of Directors. This amendment preserves the exposure of the corporation to civil fraud penalties while increasing flexibility of companies to choose who' will certify. It therefore appears to be a significant improvement over the original. Certainly, it represents much study and consultation with contradicting agencies by OFPP. That is exactly as it should be, for the task of improving regulations is committed in our legal system not to courts but to the regulators.
Congress too has now acted, fulfilling its own proper role; it has changed the law. Thus, the “certification problem” that so concerned the dissent has been resolved. And therefore any call to take this case in banc to revisit the Grumman issue, even if permissible under Fed.Cir.R. 35, seems all the less persuasive. In any event, as explained earlier, the requirements of Rule 35 plainly are not met. Finally, while its effect has been ameliorated by Congress, Grumman has not been shown erroneous by the dissent. Neither has the decision in this appeal.
CONCLUSION
For the reasons stated above, the decision of the ASBCA in No. 33244, 91-2 BCA ¶ 23,-865, reconsideration denied, 91-3 BCA ¶ 24,-132 (1991), is
AFFIRMED.
. Federal Circuit Rule 35(a) provides:
In banc consideration, whether upon initial hearing or rehearing, is an extraordinary procedure. Upon initial hearing, the case must require answer to a precedent-setting question of exceptional importance. On rehearing, the case must require either answer to a precedent-setting question of exceptional importance or resolution of a conflict between the panel opinion and precedent of the Supreme Court of the United States or of this circuit.
Although only the court in banc may overrule a binding precedent, a party desiring to argue for overruling need not make a suggestion for hearing in banc but may so argue in its principal brief and at oral argument, relegating to the panel any request to be made of the active judges to decide the case in banc.
(Emphasis added.)
. As of October 29, 1992, the United States Claims Court became the “United States Court of Federal Claims,” pursuant to Title IX of the Federal Courts Administration Act of 1992, Pub.L. No. 102-572, 106 Stat. 4506.
. Additionally, NNS asserts that the certification regulation does not have the force and effect of law because the OFPP did not provide an opportunity for notice and comment before promulgating the regulation. Brief for Appellant at 23. In fact, however, the OFPP gave notice of the availability of draft FAR part 33 and requested comment in the Federal Register. 46 Fed.Reg. 9669-70 (Jan. 29, 1981) (comments due on or before Mar. 31, 1981). On September 19, 1983, FAR 33.207(c)(2) appeared as FAR 33.007(c)(2) in the Federal Register in final form. 48 Fed.Reg. 42349, 42350 (effective Apr. 1, 1984).
. In its opinion on NNS’ motion for reconsideration, the ASBCA erroneously implies that Grumman did not decide whether FAR 33.207(c)(2) is substantive or interpretative. Reconsideration op. at 3. If not explicit, then at least a necessary implication of Grumman is that the regulation was issued under congressional authority. However, the ASBCA's unduly narrow view of Grumman did not affect NNS' rights and therefore cannot constitute reversible error.
.Instead, NNS tries to draw an analogy to various boards of contract appeals' denials of government motions to dismiss for lack of jurisdiction because of the failure of contracting officers' final decisions to inform the contractors of their rights to appeal, which 41 U.S.C. § 605(a) (1988) requires. But board decisions do not bind us. *1553And the factual and procedural context of section 605(a) cases is distinguishable. Any harm is to the contractor, so the government may lack standing to file such motions. In any event, this failure of notice has no logical connection to whether a board has jurisdiction. Thus, it is not clear how the requirements of section 605(a) can be considered jurisdictional. Certainly, there is no decision of our court so holding.
. NNS seems to contend that Lehman erred in holding the CDA certification provision to be jurisdictional. Brief for Appellant at 11 n. 7. Presumably, the unbroken line of cases based on Lehman, including Grumman and Ball, Ball & Brosamer, per NNS is similarly wrong. We disagree. In addition, we have no basis to upset this well reasoned and binding precedent, and-NNS has presented neither persuasive arguments nor authority for us to do so.
. Although the ASBCA questioned the propriety of NNS’ submission of Mr. Edward J. Campbell’s affidavit with its motion for reconsideration, the ASBCA apparently considered that evidence in rendering its decision and did not otherwise exclude this evidence or strike it from the record. Reconsideration op. at 2-3. Mr. Campbell’s affidavit is thus both part of the record before us and the ground of the Board decision we review.
. NNS contends that Grumman held that the certifying official’s position in the chain of command is pertinent only to FAR 33.207(c)(2)(i). Since the ASBCA relied on the chain of command evidence in the FAR 33.207(c)(2)(ii) inquiry, NNS argues that it committed reversible error. NNS misconstrues Grumman. Grumman did not reject the relevance of the certifier's position in the chain of command to FAR 33.-207(c)(2)(B). In fact, the Grumman court did consider but hot rely on chain of command evidence to decide the "overall responsibility” question, finding the certifier unqualified primarily because he only had financial duties. Nevertheless, a certifying official's position in the chain of command may clearly be material to whether the person has overall responsibility. Moreover, given Mr. Burling's own testimony concerning how limited his duties were, any ASBCA error did not harm or prejudice NNS.
. NNS faults the ASBCA, when analyzing the requirements of FAR 33.207(c)(2)(B), for considering the number of people to whom Mr. Burling was subordinate. NNS again contends such fact is only relevant with respect to the "in charge” inquiry of the first prong, i.e., FAR 33.-207(c)(2)(i). As noted supra, this fact is actually relevant to both parts of the FAR, although no cases specifically so hold. In any event, because Mr. Burling did not otherwise satisfy FAR 33.-207(c)(2)(h), the ASBCA at most committed harmless error. :
. The dissenting judge himself joined in the unanimous panel opinion in Ball, Ball & Bro-samer, the 1989 Federal Circuit decision heavily relied on and frequently cited as controlling in Grumman. While Grumman applied the FAR to another type of official, Ball, Ball & Brosamer had once again previously (1) upheld the FAR as permissible under the CDA; (2) once again found compliance with it a jurisdictional prerequisite; and (3) applied it literally to a Chief Cost Engineer. Therefore, it was Ball, Ball & Brosamer, which our brother then joined, not Grumman about which he now complains, that created the requirement of literal compliance with the FAR in our precedent. Ball, Ball & Brosamer also continued the rule established over 10 years ago by the Court of Claims that proper certification is jurisdictional. Of course, Court of Claims decisions are binding precedent on us as they were on the Ball, Ball & Brosamer -and Grumman panels. Needless to say, our panel is also bound by Ball, Ball & Brosamer itself.
. The dissent argues that the certification requirement should not be deemed jurisdictional in light of the language of the statute. As we explain infra in Section III, however, the dissent's argument is not correct for the literal language of the two applicable sections, taken together, actually requires proper certification of large claims in order for the contracting officer to have jurisdiction to render a valid final decision, an express statutory prerequisite to an appeal to a contract board or a suit in the Claims Court.
. A majority of the court has already expressly declined in banc review of Grumman, 927 F.2d at 581 n. 1. Only four of 10 active judges voted to take Grumman in banc. Moreover, like the Ball, Ball & Brosamer panel, the Grumman panel was unanimous. Nor are the three members of the Grumman panel the only judges of our court to have ruled consistently with Grumman. Three other judges unanimously joined a similar interpretation in Ball, Ball & Brosamer. Two more judges did so in Universal Canvas, 975 F.2d at 847, and one more did so in Kiewit, 981 F.2d at 531. They in turn follow numerous other judges who similarly ruled in cases going back 10 years. Therefore, the rule must be considered well-settled and considerations of stare decisis strongly impede revisiting and revising it.
. The exception may be in ship-building contracts where the special and short statute of limitations of 18 months would often bar consideration of a recertified and resubmitted claim.
