(concurring).
I am in full accord with the opinion of the majority holding that the scope of review standard articulated by the district court is too narrow and that the appeal must, therefore, be remanded for further proceedings. I also agree that our prior decision in Cohen v. Ryder, 373 F.2d 530 (1967), did not deal fully with the issue of scope of review in cases of this kind and is thus not inconsistent with what we decide here. However, I cannot go all the way with the position adopted by the majority that in cases involving discharge of government employees the substantial evidence test is one of the standards of review to be followed in addition to whether the agency action (1) has met all procedural requirements, and (2) was arbitrary, capricious or an abuse of discretion — but more on that score later.
At the outset it should be noted that there may be a serious jurisdictional question posed here as well. The instant action seeking reinstatement and *396back pay because of an allegedly improper dismissal from government service was brought “under the provisions of the Administrative Procedure Act, 5 U.S.C. 1001, et seq. [now 5 U.S.C. § 701 et seq.] * * * ” Appellant’s Appendix la. There continues to be a dispute in the courts and in academic circles as to whether the Administrative Procedure Act is jurisdictional, i. e., whether the Act itself is an affirmative grant of jurisdiction to the district courts to review agency action according to its terms absent any other basis for federal jurisdiction. See, e. g., Toilet Goods Ass’n., Inc. v. Gardner, 360 F.2d 677, 679 n. 1 (2d Cir. 1966), aff’d, 387 U.S. 158, 87 S.Ct. 1520, 18 L.Ed.2d 697 (1967); Cappadora v. Celebrezze, 356 F.2d 1 (2d Cir. 1966); Ove Gustavsson Contracting Co. v. Floete, 278 F.2d 912 (2d Cir.), cert. denied, 364 U.S. 894, 81 S.Ct. 225, 5 L.Ed.2d 188 (1960); Powelton Civic Home Owners Ass’n. v. HUD, 284 F.Supp. 809, 819-820 (E.D.Pa.1968). See also Jaffe and Nathanson, Administrative Law—Cases and Materials 288 (3d ed. 1968); Jaffe, Judicial Control of Administrative Action 528 (1965); 3 Davis, Administrative Law Treatise 291 (1958); Byse and Fiocca, Section 1361 of the Mandamus and Venue Act of 1962 and “Nonstatutpry” Judicial Review of Federal Administrative Action, 81 Harv.L.Rev. 308, 326-331 (1967).
In Local 542, International Union of Operating Engineers v. N.L.R.B., 328 F.2d 850 (3d Cir.), cert. denied, 379 U.S. 826, 85 S.Ct. 52, 13 L.Ed.2d 35 (1964), this court characterized the Administrative Procedure Act as being “clearly remedial and not jurisdictional” and stated that there “is nothing in Section 10 or any other clause of the Act which extends the jurisdiction of either the district courts or the appellate courts to cases not otherwise within their competence.” Id. at-854.
Although the Supreme Court has not expressly decided the issue, decisions of the Court, both prior and subsequent to our Local 5k2 ease, offer support to the position that one “suffering legal wrong because of agency action, or adversely affected or aggrieved by agency action within the meaning of a relevant statute, * * * ” 5 U.S.C. § 702, may seek review of such action under the Administrative Procedure Act. See, e. g., Abbott Laboratories v. Gardner, 387 U.S. 136, 140-141, 87 S.Ct. 1507, 18 L.Ed.2d 681 (1967); Rusk v. Cort, 369 U.S. 367, 371-372, 82 S.Ct. 787, 7 L.Ed.2d 809 (1962).
In any event, the power of the courts to review claims by government employees alleging improper dismissal is too well established to be rejected here. Although the basis for such review has not always been clearly spelled out, the following cases are illustrative of the different ways in which agency action has been brought up for review: Meehan v. Macy, 392 F.2d 822 (D.C.Cir. 1968) (complaint sought a declaratory judgment and a mandatory injunction to remedy an allegedly illegal discharge); Taylor v. United States Civil Service Commission, 374 F.2d 466 (9th Cir. 1967) (suit in nature of mandamus seeking reinstatement and damages for wrongful dismissal); McTiernan v. Gronouski, 337 F.2d 31 (2d Cir. 1964) (mandamus action pursuant to 28 U.S.C. § 1361 seeking reinstatement); Pelicone v. Hodges, 320 F.2d 754 (D.C.Cir.1963) (characterized, as are many District of Columbia cases, as a “government employee discharge case”); Mendez v. Macy, 292 F.Supp. 802 (S.D.N.Y.1968) (action brought pursuant to Administrative Procedure Act and Declaratory Judgment Act). See Byse and Fiocca, supra at 342 (1967). Suits are also brought before the United States Court of Claims seeking back pay or damages for wrongful dismissal. See, e. g., Armstrong v. United States, 405 F.2d 1275, cert. denied, 395 U.S. 934, 89 S.Ct. 1997, 23 L.Ed.2d 449 (1969); Heffron v. United States, 405 F.2d 1307 (1969).
Assuming that an action of this type may properly be brought under the Administrative Procedure Act, or that in a reinstatement case reference to the Administrative Procedure Act for the *397standards governing review of agency-action is permissible, a further question arises. The Administrative Procedure Act excepts from its coverage agency action “committed to agency discretion by law.” 5 U.S.C. § 701(a) (2). The dismissal of government employees has usually been held to involve matters of discretion,1 and the question thus presented is whether any of the standards of review now contained in the Administrative Procedure Act, 5 U.S.C. § 706, may be applied in this kind of case. Stated another way, does the § 701 exception for cases involving agency discretion exempt from review dismissals which may constitute an abuse of discretion or arbitrary and capricious action or otherwise violate the Act? To say that the controversy on this question Has-been heated' is perhaps an understatement.2 I am inclined to the view that agency action resulting in the discharge of an employee, though obviously involving discretion, is subject to review when it is asserted that the discretion has been abused or has been exercised in an arbitrary manner. Cf. Cappadora v. Celebrezze, 356 F.2d 1, 5-6 (2d Cir. 1966).
Assuming that this case is properly brought under the Administrative Procedure Act, or that the Administrative Procedure Act provides the applicable standards for the district court to apply in employee discharge cases, I do not believe that the full sweep of the standards of review adopted by the majority opinion is clearly supported by the Administrative Procedure Act itself or by the case law.
The scope of review section of the Administrative Procedure Act, 5 U.S.C. § 706, provides af follows:
To the extent necessary to decision and when presented, the reviewing court shall decide all relevant questions of law, interpret constitutional and statutory provisions, and determine the meaning or applicability of the terms of an agency action. The reviewing court shall—
(1) compel agency action unlawfully withheld or unreasonably delayed; and
(2) hold unlawful and set aside agency action, findings, and conclusions found to be—
(A) arbitrary, capricious, an abuse of discretion, or otherwise not in accordance with law;
(B) contrary to constitutional right, power, privilege, or immunity;
(C) in excess of statutory jurisdiction, authority, or limitations, or short of statutory right;
(D) without observance of procedure required by law;
(E) unsupported by substantial evidence in a case subject to sections 556 and 557 of this title or other*398wise reviewed on the record of an agency hearing provided by statute; or
(F) unwarranted by the facts to the extent that the facts are subject to trial de novo by the reviewing court.
In making the foregoing determinations, the court shall review the whole record or those parts of it cited by a party, and due account shall be taken of the rule of prejudicial error. (Emphasis added.)
Thus there appear to be three principal standards of review in government employee dismissal cases suggested by the Administrative Procedure Act quoted above or by case law generally:
(1) whether there has been procedural regularity, i.e., compliance with statutory and other requirements for the giving of notice, conduct of hearings, allowance of appeals and the like;
(2) whether the agency action is arbitrary, capricious or an abuse of discretion (5 U.S.C. § 706(2) (A) ); or
(3) whether the agency action is supported by “substantial evidence.” (5 U.S.C. § 706(2) (E).)
The second and third tests I do not consider to be the same. While agency action which is arbitrary and capricious,3 or which constitutes an abuse of discretion,4 would no doubt be action which is “unsupported by substantial evidence,” the reverse is not true. In other words, even where the agency action is not arbitrary and capricious or an abuse of discretion, there may still not be “substantial evidence” in the accepted use of that test to justify the agency action. The very listing of the substantial evidence test as a separate and alternative ground for reviewing agency action indicates a legislative intent that it be a different standard from that permitting the setting aside of the findings or conclusions of an agency as arbitrary, capricious or an abuse of discretion.5
While admittedly some courts have articulated the substantial evidence test in government employee cases, usually without reference to the Administrative Procedure Act, I have been unable to find a clear explanation of the basis for the use of such test. And in some of the instances in which this test was mentioned, the court was able to find that the agency action was or was not arbitrary and capricious and did or did not lack substantial evidence to support it, without having to pin down the precise test which must be followed.6 In remanding this appeal to the district court, where we find that the procedural *399regularity standard applied by the trial judge is too narrow,7 I think we have an obligation to formulate as clearly as possible the proper tests to be followed.
Looking to the precise language of the “substantial evidence” rule of the Administrative Procedure Act, 5 U.S.C. § 706(2) (E), we find that it applies only in a case
(1) which is subject to §§ 556 and 557 of Title’ 5; or
(2) which is “otherwise reviewed on the record of an agency hearing provided by statute.” (Emphasis added.)
Sections 556 and 557 deal with the procedure to be followed when an agency is required to hold a hearing, and these sections seem to apply only to those hearings provided by 5 U.S.C. §§ 553 and 554. The former, § 553, relates to rule-making and is inapplicable here. Section 554, which deals with adjudications, is limited in its application to adjudications “required by statute to be determined on the record after opportunity for an agency hearing * * *.” 5 U.S.C. § 554(a). And even then there is an exception, § 554 not being applicable if the adjudication involves the selection or the tenure of an employee. 5 U.S.C. § 554(a) (2). Thus, even if by statute government employees were entitled to a hearing in dismissal cases, 5 U.S.C. § 554(a) (2) seems to preclude the courts from applying the substantial evidence test when review of adverse agency action involving an employee’s tenure is sougnt.
The alternative ground for applicability of the substantial evidence rule, i.e., where the agency action is “reviewed on- the record of an agency hearing provided by statute,” is also inapplicable because the statutes dealing with the removal or suspension of individuals in the competitive service, including those who have veterans preference, do not expressly create the right to a hearing, although a hearing is permitted. See 5 U.S.C. §§ 7501, 7512. While federal employees have now been afforded a right to an administrative hearing by virtue of Executive Order No. 10987, January 17, 1962, 5 U.S.C.A. § 7501, and the implementing civil service regulations, 5 C.F.R. §§ 771.213, 772.305, it would, in my opinion, be stretching the language of the Administrative Procedure Act to hold that such hearings are provided by statute.
Furthermore, I do not read the cases relied upon by the majority as clearly and definitively supporting the proposition for which they were advanced. Though the words “substantial evidence,” or their equivalent, appear in the cited cases, when the opinions are read in their entirety and fully analyzed it is less than clear that the substantial evidence test is being directly applied or followed.8
*400In my view the proper scope of review in cases of this type is limited to ascertaining whether applicable procedural requirements have been met and whether the agency action was arbitrary, capricious or an abuse of discretion.9 Beyond this, I would not go. Certainly the agency record should be carefully examined, for agency action totally devoid of factual support would warrant, if not compel, a determination that the action was arbitrary or capricious. But where under the governing statute removal may only be “for such cause as will promote the efficiency of the service,” I believe it is neither advisable nor permissible for the courts to exercise the broad degree of scrutiny adopted by the majority.
In concluding, I would observe that we are here dealing with a problem that merits statutory clarification both as to the jurisdictional basis for review and the scope of review so afforded. If the cases make anything clear, it is the desirability of Congressional action in this murky and troublesome area.10
. A government employee in the competitive service may be removed “only for such cause as will promote the efficiency of the service.” 5 U.S.C. § 7501. By its very nature, the issue of “efficiency” is “a matter peculiarly discretionary.” Jaffe, Judicial Control of Administrative Action 372 (1965). The great majority of the employee discharge cases appear to recognize that the taking of disciplinary action against government employees is a matter of executive discretion. Courts should be alert to protect procedural rights and to guard against arbitrary action, but to engage in wholesale review-on the merits would, under the present state of the law, be an unwarranted intrusion into the affairs of another branch of the Government.
. See Berger, Administrative Arbitrariness and Judicial Review, 65 Col.L.Rev. 55 (1965); 4 Davis, Administrative Law Treatise § 28.16 (Supp.1965). Then see the replies and counter-replies of those authors at 114 U.Pa.L.Rev. 783, 814, 823 (1966) . See also Jaffe and Nathanson, Administrative Law-Cases and Materials 247 (3d ed. 1968); Jaffe, Judicial Control of Administrative Action 374 (1965); Saferstein, Nonreviewability: a Functional Analysis of “Committed to Agency Discretion,” 82 Harv.L.Rev. 367 (1968); Murphy, Judicial Review of the Removal of Federal Employees: A Reexamination, 22 Fed.B.J. 25, 27 (1962).
. I would construe arbitrary and capricious action as a dismissal of a government employee which is due to bias or prejudice, or which constitutes excessive punishment under the circumstances, or which has little or no evidence to support it.
. “Broadly stated an abuse of discretion is an exercise of discretion in which a relevant consideration has been given an exaggerated, an ‘unreasonable’ weight at the expense of others. The ‘letter’ has been observed; the ‘spirit’ has been violated. Discretion implies a ‘balancing’; where the result is eccentric, either there has not been a balancing, or a hidden and mayhap improper motive has been at work.” Jaffe, Judicial Control of Administrative Action 586 (1965).
. Cf. Lewis v. American Federation of State, County and Municipal Employees, AFL-CIO, 407 F.2d 1185 (3d Cir. 1969), in which we held that the requirements of the Labor-Management Reporting and Disclosure Act (LMRDA) of 1959 that no union member may be disciplined unless he was “afforded a full and fair hearing” fixes a standard which is something less than the substantial evidence rule but something more than the mere requirement of procedural regularity.
Davis has stated, it is interesting to note, that: So strong is the judicial tendency toward the substantial evidence rule that the rule is often followed even where the statute prescribes a narrower or a broader scope of review. 4 Davis, Administrative Law Treatise 115 (1958).
Professor Davis generally believes that attempts to narrow or change the substantial evidence rule have proved unfruitful. Id. at 126, 149.
. See, e. g., Meehan v. Macy, 392 F.2d 822, 830, 837 (D.C. Cir. 1968); Taylor v. United States Civil Service Commission, 374 F.2d 466, 470 (9th Cir. 1967).
. As indicated in the majority opinion in note 6 and the accompanying text, there is case support for the application of this narrow rule, but I agree the standard is too limited. I part with the majority, however, in the very broad tests which the court would permit the district court to apply, as I believe that, in addition to procedural regularity, the only other proper ground for review is whether the action was arbitrary, capricious or an abuse of discretion.
. Professor Davis concludes that there has developed a “common law” of review of administrative action in employee discharge cases under the “substantial evidence” standard: 4 Davis, Administrative Law Treatise § 28.05, p. 18 n. 5 (1958). See also the references to the Davis Treatise in note 5, supra.
The Meehan Halsey and Dabney cases cited by the majority do seem to apply the substantial evidence rule, the Meehan ease, involving a vital free speech issue, perhaps justifying the more liberal scope of review. A recent district court decision flatly follows the substantial evidence test of the APA. Mendez v. Macy, 292 F.Supp. 802, 804 (S.D.N.Y.1968).
It is less clear that the Pelicone and Taylor cases directly apply the substantial evidence test. Pelicone relied on the “arbitrary and capricious” standard as well as the fact that there was “no evidence” to support the charges against the employee. In Taylor, after determining that the employee’s dismissal was not in violation of procedural requirements and was not arbitrary or capricious, the court concluded also that the *400action of the Civil Service Commission was supported by substantial evidence. 374 F.2d at 469, 470. (This is similar to Lewis v. American Federation of State, County and Municipal Employees, AFL-CIO, supra note 5, where, after deciding that the substantial evidence rule did not apply in a LMRDA case, we nevertheless found it appropriate to say that on the particular record in that case, even if the rule were applicable, there was “substantial evidence” to support the expulsion from union membership there challenged. 407 F.2d at 1198.)
Meehan, Dabney and Pelicone were District of Columbia Circuit Court appeals. Earlier District of Columbia cases, Hofflund v. Seaton, 105 U.S.App.D.C. 171, 265 F.2d 363, cert. denied, 361 U.S. 837, 80 S.Ct. 55, 4 L.Ed.2d 77 (1959), and Hargett v. Sommerfield, 100 U.S.App.D.C. 85, 243 F.2d 29 (1957), followed the narrowest of the possible tests, the procedural regularity rule.
The Court of Claims which, like the District of Columbia Circuit, has had occasion to decide many government employee dimsissal cases, has followed different standards at different times, as evidenced recently by two cases decided the same day. In Armstrong v. United States, 405 F.2d 1275, 1277 (1969), cert. denied, 395 U.S. 934, 89 S.Ct. 1997, 23 L.Ed.2d 449 (1969), the court said that absent any showing that the Civil Service Commission finding in the case “was arbitrary and capricious, it must stand.” In Heffron v. United States, 405 F.2d 1307, 1310 (1969), the court said that it “ * * * will accord finality to an administrative decision to remove unless' it is shown that it is arbitrary or not supported by substantial evidence.”
I have adverted to these cases, and there are many others that could be cited, not to quibble with language but to show the distressing absence of uniformity in the scope of judicial review in employee discharge appeals. Some district courts have recognized the uncertainty in this field as, e. g., Veatch v. Resor, 266 F.Supp. 893, 896 (D.Col. 1967), where the court said:
* * * Some courts have limited the review to an inquiry: 1) whether the removal violated some statutory provision; and 2) whether the procedures established were followed. Other courts have inquired as to whether the administrative decision was supported by substantial evidence or was arbitrary and capricious. These standards are included within the Administrative Procedure Act. Whether this act applies to a review such as the present one is questionable and unnecessary to a determination of the case at bar since judged by any of the mentioned standards the plaintiff’s discharge must be upheld. * * * (Footnotes omitted.)
. Jaffe, Judicial Control of Administrative Action 371 (1965).
. In Connelly v. Nitze, 401 F.2d 416, 417 n. 1 (D.C. Cir. 1968), Judge McGowan stated:
We have pointed out before that these employee discharge eases, although in form original actions in the District Court, are in reality agency review proceedings and are normally treated as such by all parties. Dabney v. Freeman, 112 U.S.App.D.C. 166, 358 F.2d 533 (1965). This creates difficulties, as here, in our ability to give, effectively and expeditiously, the most appropriate kind of relief- It also raises questions as to why Congress should not provide for statutory direct review of Civil Service Commission determinations in employee cases, comparable to that now employed in respect of other major federal administrative agencies.
