These consolidated appeals1 *are from orders of the District Court denying intervention in a suit to review and set aside certain determinations by the Secretary of Labor under the Walsh-Healey Act.2 The determinations fixed “the prevailing minimum wages” at a national level for the woolen and worsted industry in manufacturing goods under contracts with the Government. They raised previously determined mínimums which had been fixed on a regional level.
Our appellees are employers in the industry, operating in regions where the prevailing wages are lower than the national level. They opposed these changes in the administrative proceeding and brought the suit for review in the District Court as “persons adversely affected or aggrieved” under the Fulbright Amendment to the Walsh-Healey Act.3
The following is a brief description of the appellants and their respective interests in the determinations which they instigated before the Secretary and now seek to defend by intervention in the review proceeding. Appellant in No. 12331 is a union of employees which will enjoy increased wages under the determination. Appellant in No. 12374 is an employer competing with the appellee companies in bidding for Government contracts and operating in a region where the prevailing rates are even higher than those fixed by the Secretary; hence its ability to compete with the appellees for Government business will be effectively destroyed if appellees succeed in their attack upon these determinations.
Appellees point to the Supreme Court’s holding in Perkins v. Lukens Steel Co. that Walsh-Healey determinar *767tions are not judicially reviewable.4 From this they argue that the absence of any reference to intervention in the subsequently enacted Fulbright Amendment, granting aggrieved persons judicial review to attack the determinations, must be construed to preclude intervention in such review by persons who would be commensurately aggrieved if the determinations were set aside.5 We think this argument untenable. The Fulbright Amendment creates the right of action which brings the case into court. Once there, the case is governed by the principles which control the course of all litigation in the District Court.
Nor do we agree with appellees’ contention that these principles, reflected in Rule 24 of the Federal Rules of Civil Procedure, 28 U.S.C.A., bar the interventions sought here.
Rule 24 provides:
“(a) Intervention of Right. Upon timely application anyone shall be permitted to intervene in an action: * * * (2) when the representation of the applicant’s interest by existing parties is or may be inadequate and the applicant is or may be bound by a judgment in the action * *
“(b) Permissive Intervention. Upon timely application anyone may be permitted to intervene in an action: * * * (2) when an applicant’s claim or defense and the main action have a question of law or fact in common. * * * In exercising its discretion the court shall consider whether the intervention will unduly delay or prejudice the adjudication of the rights of the original parties.” 6
Obviously tailored to fit ordinary civil litigation, these provisions require other than literal application in atypical cases. Administrative cases, as the present one demonstrates, often vary from the norm.
In conventional litigation, one is bound by a judgment in the action, within the meaning of Rule 24(a), when* the judgment is res judicata as to him.7 Appellants in this case were not parties in a technical sense to the administrative proceeding; nevertheless they are “bound” by the determinations therein in a very practical sense. Authoritative rulings made in this proceeding fixed a wage at a national level. These rulings are under attack in the suit for review below. It is true that, if the attack succeeds, the final judgment would preclude neither the appellants nor the appellees from later pressing their interests at the administrative level. But ultimate victory at that point cannot overcome the “practical disadvantage” to which appellants may be subjected as a result of the prior judicial action.8 For example, if the deter*768minations are upset, the membership of the appellant union will be deprived of economic benefits. That the union may subsequently receive other benefits from new determinations which it may procure cannot compensate for the losses suffered in the interim. Nor does the fact that the union may bargain for a wage higher than the minimum convince us that it and its members are not bound, in a practical sense, by minimum wage determinations. Similarly,- if the appellant-employer is forced out of business by an injunction restraining the effectuation of the wage determinations, he can take little solace from a subsequent moral victory. Hence we think that the strict test of res judicata is inappropriate in applying Rule 24(a) to the present case.
The right of the appellants to intervene is not affected by the fact that the general position they assert is already represented in the action by the Secretary of Labor. The Secretary’s response to the motions to intervene declares that neither the appellants nor the appellees can show themselves to be directly affected by the determinations. This is hardly an assurance, of adequate representation for the appellants.9 Even if the Secretary espoused the appellants’ interests with greater heart, it would not necessarily preclude their appearance to plead for themselves.10
Generally “a claim of an absolute right to intervene must be based upon the language of Rule 24(a).”11 But this rule is not “a comprehensive inventory of the allowable instances for intervention” as of right. Missouri-Kansas Pipe Line Co. v. United States, 1941, 312 U.S. 502, 505, 61 S.Ct. 666, 85 L.Ed. 975. In that case, in reversing an order denying intervention, the Supreme Court was not concerned with the distinctions between 24(a) and (b). In fact, the Court spoke in terms of permissive intervention :
“We are not here dealing with a conventional form of intervention, whereby an appeal is made to the court’s good sense to allow persons having a common interest with the formal parties to enforce the common interest with their individual emphasis. Plainly enough, the circumstances under which interested outsiders should be allowed to become participants in a litigation is, barring very special circumstances, a matter for the nisi prius court. But where the enforcement of a public law also demands distinct safeguarding of private interests by giving them a formal status in the decree, the power to enforce rights thus sanctioned is not left to the public authorities nor put in the keeping of the district court’s discretion.” 12
In that case, a consent decree specifically provided for such intervention. But the teaching of the case is not so narrowly limited. It expresses generally the proposition that failure to come within the precise bounds of Rule 24’s provisions does not necessarily bar intervention if there is a sound reason to allow it.13
*769Even if 24(a) were inapplicable here, we are convinced that appellants would be entitled to intervene under the terms of 24(b). Appellees concede that appellants may have a “general interest” in the subject of the suit, but they assert that this interest does not constitute a “claim or defense” as required by the rule. Principal reliance is placed on Jewel Ridge Coal Corp. v. Local 6167.14 But, as Professor Moore points out, in commenting upon the Jewel Ridge ease and others of similar purport, intervention has been allowed in situations where “the existence of any nominate ‘claim’ or ‘defense’ is difficult to find.” 15 And establishing a “claim or defense” for purposes of permissive intervention is, of course, not dependent upon a showing of “direct pecuniary interest” in the litigation.16
In any event, appellants have much more than a “general interest” to protect. They have a real economic stake in the outcome of this litigation. It is similar to the interest which prompted this court to approve the trial court’s grant of intervention in Champ v. Atkins,17 the principal example cited by Professor Moore in his comment on the Jewel Ridge case. There members of a taxicab association sought a judgment declaring that their driving permits should not be suspended for nonpayment of a judgment. The judgment creditor, who was permitted to appear, obviously could present no “claim or defense” in the technical sense. But we recognized that the creditor’s “economic interest” in inducing payment of the debt, which was likely to occur with suspension of the taxi drivers’ licenses, was sufficient to justify intervention under Rule 24.18
It is clear, too, that there is a common question of “law or fact” at issue. Ap-pellees have an economic interest in invalidating the wage determinations. The appellants’ interests lie in supporting them. Multiplicity of suits can be avoided by settling such related controversies in a single action. Upon this ground, intervention was allowed in Brotherhood of Locomotive Engineers v. Chicago, M. St. P. & P. R. R.19 There a firemen’s union was allowed to become a party to a suit by an engineers’ union to construe an agreement with the railroad dealing with work for its members. The firemen’s union contended that any additional work days won by the engineers would be at the expense of the firemen. The court recognized that excluding the firemen from the engineers’ action might necessitate a separate suit to construe the firemen’s contract. Here, too, if appellants are excluded from this action, and a judgment is entered invalidating the wage determinations, appellants will eventually bring the controversy back to court to assert the position they ask to present now. The same issues, both of law and fact, would be involved.
In exercising its discretion under Rule 24(b), the court must be governed in no small part by the likelihood of undue delay resulting from intervention. Here appellants’ interests demand the speediest possible conclusion of the controversy because the wage determinations they have been striving for are stayed pend*770ing the outcome of this suit. Clearly, the only interest that might be served by delay would be that of the appellees.
Under the circumstances of this case, then, we think the denial of appellants’ petitions to intervene exceeded the limits of discretion. As we said in Wolpe v. Poretsky, appellants “have such a vital interest in the result of [the] suit that they should be granted permission to intervene as a matter of course unless compelling reasons against such intervention are shown.”20 No such “compelling reasons” appear here.21
The interventions sought here would serve the ends of justice. They would also promote judicial and administrative convenience by avoiding a multiplicity of proceedings and by bringing to the aid of the tribunal the parties who “may know the most facts and can best explain their implications.” 22 Reversed and remanded.
WASHINGTON, Circuit Judge, took no part in the rehearing and decision of the above entitled cases.
BASTIAN, Circuit Judge, with whom WILBUR K. MILLER, Circuit Judge, concurs (dissenting).
I am unable to agree with the decision of the majority. In each of these consolidated cases the District Court denied the right of the appellant to intervene as a party defendant on the side of the Secretary of Labor in a case pending in the District Court entitled Allendale Co., et al. v. Mitchell, Secretary of Labor, Civil Action No. 1630-54.
Under Section 1 of the Walsh-Healey Act,1 it is provided that there shall be included certain representations and stipulations in every government contract for the manufacture or furnishing of materials, supplies, articles and equipment in any amount exceeding $10,000.00. One of these representations and stipulations is that all persons employed by the contractor shall be paid “not less than the minimum wages as determined by the Secretary of Labor to be the prevailing minimum wages for persons employed on similar work or in the particular or similar industries or groups of industries currently operating in the locality in which the materials, supplies, articles, or equipment are to be manufactured or furnished under said contract.”
Pursuant to the said act, the then Secretary of Labor issued a prevailing minimum wage determination for the Woolen and Worsted Industry; and, on April 1, 1954, the Secretary promulgated an amendment providing that the prevailing minimum wage for the Broad-Woven *771Goods, Yam and Thread Branch of the Woolen and Worsted Industry and for Pressed Felt thenceforth would be $1.20 an hour, and that the prevailing sub-minimum rate for learners and beginners contracts would be $1.05 an hour.
Thereafter, the suit in which appellants seek to intervene (i. e., Civil Action No. 1630-54) was filed, the plaintiffs in that suit alleging that they were prospective bidders on future government contracts operating in regions where the prevailing wages are lower than the national level. Those plaintiffs seek to permanently enjoin the Secretary of Labor from putting into effect the April 1, 1954 amendment, and ask that the amendment be declared invalid. The complaint also alleged, among other things, that the wage determinations were nationwide in their application, whereas the Walsh-Healey Act provides that the determination shall be at prevailing minimum wages in the locality in which the materials, supplies, articles or equipment are to be manufactured or furnished. The District Court granted an application for a stay and preliminary injunction.
On April 29, 1954, appellant Textile Workers Union of America, CIO, sought to intervene in Civil Action No. 1630-54 as party defendant on the side of the Secretary of Labor; and on May 18, 1954, appellant Hayward-Schuster Woolen Mills, Inc. sought to intervene in the same civil action as party defendant on the side of the Secretary of Labor. Both applications were denied by the District Court. These appeals followed.
The Textile Workers Union of America, CIO, represents as bargaining agent six of the named plaintiffs in the civil action referred to, and also represents employees of other mills in the industry that have not joined as plaintiffs. It is claimed by the Union that its intervention will insure that a decision vitally and directly affecting wage contracts of the Woolen and Worsted Industry will not be made without affording the employees in that industry an opportunity to be heard.
It is claimed on behalf of Hayward-Schuster Woolen Mills, Inc. that it operates as an employer bidding for government contracts in a region where the prevailing rates are even higher than those fixed by the Secretary, and that, therefore, the construction of the Walsh-Healey Act as urged by the plaintiffs would result unfavorably to this appellant.
First, appellants claim that intervention is permitted by Section 10 of the Walsh-Healey Act, known as the Fulbright Amendment. This amendment is quoted in the margin.2 3
A reading of Section 10(b) of the Fulbright Amendment shows by its terms that review of the wage determination can be granted only to a person “adversely affected or aggrieved thereby” (underscoring supplied) and, certainly, neither appellant is so affected or aggrieved, as they both support the position of the *772Secretary of Labor. The obvious purpose of Section 10(b) is to give a person “adversely affected or aggrieved” the opportunity to contest the action of the Secretary, which was not possible under the holding in Perkins v. Lukens Steel Co., 310 U.S. 113, 60 S.Ct. 869, 84 L.Ed. 1108. It gives no right to intervene in support of the administrative action.
Section 10(c) of the Fulbright Amendment has no application to the present situation because it is clear, both from the reading of this section and from its legislative history, that the term “interested person” does not cover either the union or Hayward-Schuster. It simply permits any government contractor, whose contract contains stipulations required by the Walsh-Healey Act, to obtain a judicial determination of any legal question in any appropriate proceeding, to the same extent that such question could be raised if the stipulations were not contained in the contract.
It is also claimed that appellants are entitled to intervene under Rule 24, F.R. Civ.P., quoted in the margin.3 It is obvious that conditions (1) and (3) of Rule 24(a) have no application to appellants’ right to intervene; and, under condition (2) of that rule, intervention as of right can be granted only “when the representation of the applicant’s interest by existing parties is or may be inadequate and the applicant is or may be bound by a judgment in the action.” (Italics supplied.)
Conceding, arguendo, under Rule 24 (a) (2), that appellants are or may be bound by a judgment in the civil action, certainly there is no basis for assuming that the representation of the appellants’ interests by the Secretary of Labor “is or may be inadequate.” The Secretary is defending his own action and there is no basis for holding that the Secretary is not going to defend his own judgment adequately. Certainly, nothing has been shown on the record to indicate this.
The majority, in their opinion, refer to the Secretary’s response in the District Court to the motions to intervene wherein (so the majority states) the Secretary declares “that neither the appellants nor the appellees can show themselves to be directly affected by the determinations.” 4 The majority say that this is “hardly an assurance of adequate *773representation for the appellants” and argue from this that, even if the Secretary espoused the appellants’ interests with greater heart, it would not necessarily preclude their appearance to plead for themselves. To say that the Secretary’s statement in response to the motion has anything to do with adequate representation on the main point at issue is, to say the least, a non sequitur, and is unfair to the Secretary of Labor. Certainly, this was not the meaning of his statement. Not one thing appears in the record to indicate that the Secretary will not adequately support his own findings. The decision of the majority, holding in effect that his representation “may be inadequate”, is based purely on speculation, without the slightest basis or foundation. Further, if the holding as to the meaning of the phrase, “may be inadequate”, correctly construes condition (2) of Rule 24(a), then “anyone” (with reference to Rule 24(a) (2)) is permitted to intervene without being obliged to indicate how or in what way his interests will not be adequately represented. This is not, in my opinion, the purpose of the rule.
So far as Rule 24(b) is concerned, I believe that this court in these eases has unjustly interfered with the discretion of the trial court. If the decision of the majority is correct, Rule 24(b) has been changed to read: “Upon timely application anyone shall be permitted to intervene.” There is nothing in the record to show abuse of discretion by the trial judge. He undoubtedly felt that appellants supported the action of the Secretary, as shown by their applications to intervene on his side, and that there was no reason to clutter up the case with further parties, as the Secretary would carry through with fairness; and I think the District Judge was right.
It is my opinion, therefore, that the orders appealed from should be affirmed.
. After these appeals had been argued separately before panels of this court, we ordered their consolidation and reargument before the court in banc.

. Whether Congress may constitutionally re-define as a case or controversy under Article III a dispute which the Supreme Court has held not to be such a case or controversy is a question which is likely to be determined in the appellees’ review suit. But the trial court’s conclusion, in its interlocutory order granting the preliminary injunction herein, is not yet reviewable. Nor are we hero deciding that the union would have standing to litigate the validity of a wage determination which it should deem unsatisfactory. Our only concern here is whether, unless and until the trial court decides that this litigation is beyond the judicial power, both appellants should be permitted to intervene.

The court said:
“In this case, the foundation of Reed’s right to intervene is the consent decree and injunction protecting the members of his class from discrimination and enjoining the violation of their seniority rights. It was not a conventional form of intervention; Reed, as a member of the class represented, had a right to intervene to secure the benefits of such decree.”

. Appellants are members of the class for whose benefit the wage determinations here under attack were issued and would be materially affected by an adverse decision. They should therefore be heard in defense of their interests if no prejudice would result therefrom to other parties. Wolpe v.

“Although the Act is silent on the subject of' intervention when an order of the commission comes before a court for review, it would seem that the company must have a right to intervene in such a case as this. It was the petitioner in the proceeding concluded by the order appealed from; it has an interest in the event, which the petitioners ought not be allowed to deprive it of unheard. * * ” Morris v.

“(b) All wage determinations under section 1(b) of this Act shall be made on the record after opportunity for a hearing. Review of any such wage determination, or of the applicability of any such wage determination, may be had within ninety days after such determination is made in the manner provided in section 10 of the Administrative Procedure Act by any person adversely affected or aggrieved thereby, who shall be deemed to include any manufacturer of, or regular dealer in, materials, supplies, articles or equipment purchased or to be purchased by the Government from any source, who is in any industry to which such wage determination is applicable.
“(c) Notwithstanding the inclusion of any stipulations required by any provision of this Act in any contract subject to this Act, any interested person shall have the right of judicial review of any legal question which might otherwise be raised, including, but not limited to, wage determinations and the interpretation of the terms ‘locality’, ‘regular dealer’, ‘manufacturer’, and ‘open market’.”

“(b) Permissive Intervention. Upon timely application anyone may be permitted tb intervene in an action: (1) when a statute of the United.States confers a conditional right to intervene; or (2) when an applicant’s claim or defense and the main action have a question of law or fact in common. "When a party to an action relies for ground of claim or defense upon any statute or executive order administered by a federal or state governmental officer or agency or upon any regulation, order, requirement or agreement issued or made pursuant to the statute or executive order, the officer or agency upon timely application may be permitted to intervene in the action. In exercising its discretion the court shall consider whether the intervention will unduly delay or prejudice the adjudication of the rights of the original parties.”
. As a matter of fact, the response of the Secretary to each appellant’s petition to intervene was as follows: “Without waiver of the objections previously taken by defendant in this action, defendant interposes no other objection to applicant’s Motion to Intervene.” The objections previously taken by the Secretary were to the application of Section 10(b) of the Walsh-Healey Act, as amended, to those plaintiffs who could not show they were “adversely affected or aggrieved” by the Secretary’s determination of the prevailing minimum wages, and that this provision required a showing of direct damage or injury. He could not, in my opinion, be more right as to the meaning of Section 10(b); but this does not mean he would not protect his own decision.
