This litigation, under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), 42 U.S.C. §§ 9601-9675, raises a narrow but significant procedural question of first impression in this circuit: whether non-settling potentially responsible parties (PRPs) under section 107 of CERCLA should be allowed to intervene in order to oppose a consent decree that the United States government has reached with settling PRPs. This is a consolidated suit brought by the United States (EPA) and the State of Missouri pursuant to 42 U.S.C. § 9607, to secure clean-up of hazardous substances at the site of an electrical equipment repair and salvage company and to recover the government’s response costs. Appellants, non-settling PRPs, are appealing an order of the United States District Court for the Eastern District of Missouri denying appellants’ motion to intervene pursuant to § 113® of CERCLA, 42 U.S.C. § 9613®, and Fed.R.Civ.P. 24(a) and (b), and further denying appellants’ motion to deny entry of a Consent Decree.
The parties on appeal are the plaintiff-appellees the United States (EPA) and the State of Missouri, which has deferred to the EPA in all respects on appeal; 179 defendants-appellees, known as the “settling PRPs,” who were PRPs sued in the district court and who had agreed to entry of the Consent Decree; and intervenors-appellants, a group of twelve “non-settling PRPs,” all service shop owners, and their trade association, the Electrical Apparatus Service Association (intervenors-appellants are referred to herein as “the non-settling PRPs”). We reverse and remand.
I.
A. Factual Background
The subject of this lawsuit is the clean-up of the Missouri Electric Works Site (MEW
Site) in Cape Girardeau, Missouri. An electrical equipment sale and repair shop once occupied the MEW Site, and, over a period of nearly forty years, engaged in the business of salvaging, selling, and repairing electrical equipment, including transformers. Beginning in the 1950s, transformers frequently used coolant oil containing polychlorinated biphenyls (PCBs), which, although useful in reducing the risk of transformer fires and explosions, posed a significant threat to the environment owing to their toxicity and persistence. Regulation of PCBs began in the late 1970s, but before that time, for many years, leakages and spills of PCB-laced coolant oils had been common at the MEW Site during the routine business of MEW.
The EPA discovered PCB contamination at the MEW Site in the early 1980s. Pursuant to CERCLA, the EPA identified as PRPs approximately 735 companies that had sold used transformers to MEW, junked transformers with MEW, or sent transformers to MEW for repair. The non-settling PRPs are service shop owners who either sold electrical transformers directly to MEW for resale, sold transformers to third parties who resold them to MEW, or sent transformers owned by others to MEW for repair. However, the non-settling PRPs did not not send any transformers to MEW to be scrapped or otherwise disposed of. Many of the PRPs identified by the EPA joined a “PRP Group,” which, for approximately two years, actively negotiated with the EPA concerning allocation of clean-up costs. The non-settling PRPs assert that the allocation formula arrived at in these negotiations “grossly overstated” their potential liability, because it did not allocate response costs in a way that reflected the comparative responsibilities of the various PRPs and did not correlate costs of remedial action with contaminants contributed by the parties.
In September of 1991, the EPA distributed a proposed Consent Decree to all known PRPs requiring a response within sixty days if a PRP wished to be included in the settlement. On June 29, 1992, the EPA filed suit
On November 5, 1992, the non-settling PRPs moved to intervene in this litigation. The non-settling PRPs claimed a legally pro-tectable interest in the preservation of possible contribution claims against settling defendants and an interest in not being unfairly apportioned liability for the MEW clean-up. They also asserted a legal right to intervene under Fed.R.Civ.P. 24(a) and § 113(i) of CERCLA, 42 U.S.C. § 9613(i). On March 9, 1993, the district court denied the motion to intervene.
B. The Decision Below
The opinion below appears as United States v. Union Electric Co.,
Having denied the non-settling PRPs’ motion to intervene, the court also denied the non-settling PRPs’ motion to deny entry of the Consent Decree as moot. Id. at 1008. The court then granted the EPA’s motion to enter the Consent Decree. Id.
C. The Appeal
This appeal presents an issue of first impression in this circuit. That issue is whether the district court correctly held that non-settling PRPs did not have a legally protecta-ble interest in rights to contribution stated in CERCLA § 113(f)(1) sufficient to warrant intervention pursuant to Fed.R.Civ.P. 24 or CERCLA § 113(i), 42 U.S.C. § 9613G), in a suit by the EPA against PRPs who had agreed to settle when settling PRPs would thereby obtain protection from contribution claims of non-settling PRPs pursuant to CERCLA § 113(f)(2).
The non-settling PRPs assert that “the only issue presented by the district court’s order is whether or not the Intervenor-Ap-pellants claimed an interest related to the subject of the action.” Brief of Intervenors-Appellants, at 11. The non-settling PRPs argue that they had a legally protectable interest related to the subject of the action, because their interest in contribution claims was created by the CERCLA statute itself. The EPA and the settling PRPs counter that any interest the non-settling PRPs had was too contingent or speculative to be a protect-able legal interest related to the subject of this action, and therefore the non-settling PRPs were properly denied leave to intervene. The EPA and the settling PRPs argue
II.
The non-settling PRPs assert that they should have been allowed to intervene either pursuant to Fed.R.Civ.P. 24, which governs both intervention as of right and permissive intervention, or pursuant to CERCLA § 113(i), which establishes standards for intervention in CERCLA actions comparable to those found in Fed.R.Civ.P. 24(a)(2). Fed. R.Civ.P. 24(a) provides for intervention as of right as follows:
Upon timely application anyone shall be permitted to intervene in an action: (1) when a statute of the United States confers an unconditional right to intervene; or (2) when the applicant claims an interest relating to the property or transaction which is the subject of the action and the applicant is so situated that the disposition of the action may as a practical matter impair or impede the applicant’s ability to protect that interest, unless the applicant’s interest is adequately represented by existing parties.
CERCLA provides for intervention in terms nearly identical to those of Fed.R.Civ.P. 24(a)(2):
In any action commenced under this chapter or under the Solid Waste Disposal Act [42 U.S.C. § 6901 et seq. ] in a court of the United States, any person may intervene as a matter of right when such person claims an interest relating to the subject of the action and is so situated that the disposition of the action may, as a practical matter, impair or impede the person’s ability to protect that interest, unless the President or the State shows that the person’s interest is adequately represented by existing parties.
CERCLA § 113(i), 42 U.S.C. § 9613®. The statute places the burden on the President or the State to show that the potential interve-nor’s interest is adequately represented by existing parties, 42 U.S.C. § 9613(i), while the intervenor bears the burden of showing inadequate representation by existing parties under Rule 24(a)(2). Kansas Pub. Employees Retirement Sys. v. Reimer & Roger Assocs., Inc.,
A. Intervention As Of Right
We note that the district court acknowledged some of the applicable standards for intervention pursuant to FedR.Civ.P. 24, but then failed to apply those standards, focusing instead on what it perceived to be a conflict between allowing intervention and CERC-LA’s policy of fostering prompt settlement of suits to recover clean-up costs. We find that supplanting the standards applicable to intervention as of right under Rule 24(a) with policy considerations led to the erroneous denial of intervention in this case.
This court’s standard of review for the grant or denial of leave to intervene was stated in Mille Lacs Band of Chippewa Indians v. Minnesota,
As a general proposition, whether or not a person is entitled to intervention as a matter of right is a question of law that we review de novo. United States v. Metropolitan St. Louis Sewer Dist. (MSD),883 F.2d 64 , 55 (8th Cir.1989). We review the trial court’s ruling on the timeliness of a motion to intervene, however, only for abuse of discretion. Jenkins by Agyei v. Missouri,855 F.2d 1295 , 1316 (8th Cir.1988), cert. [granted],490 U.S. 1034 ,109 S.Ct. 1931 ,104 L.Ed.2d 403 (1989), and aff'd in part on other grounds, rev’d in part on other grounds,495 U.S. 33 ,110 S.Ct. 1651 ,109 L.Ed.2d 31 (1990).
Mille Lacs,
1. Timeliness
Rule 24(a) expressly requires that a motion to intervene be “timely.”
In the present litigation, the motion to intervene was filed slightly more than four months after the suit itself was filed. The non-settling PRPs argue that their motion to intervene was timely, because no substantive activity in the case had occurred between filing of the case and filing of the motion to intervene. They point out that their motion to intervene was filed some three months prior to the EPA’s March 9, 1993, motion for entry of the Consent Decree. The EPA and settling PRPs do not specifically contest the fact that the non-settling PRPs’ motion to intervene was timely filed, but they have suggested that allowing intervention would delay the entry of the Consent Decree.
The question for determining the timeliness of the motion to intervene is whether existing parties may be prejudiced by the delay in moving to intervene, not whether the intervention itself will cause the nature, duration, or disposition of the lawsuit to change. Mille Lacs,
[prejudice that results from the mere fact that a proposed intervenor opposes one’s position and may be unwilling to settle always exists when a party with an adverse interest seeks intervention. Any prejudice to the [existing parties’] ability to settle results not from the fact of the [applicant’s] delay in seeking intervention, but rather from the [applicant’s] presence in the suit. Rule 24(a) protects precisely this ability to intervene in litigation to protect one’s interests.
Id. at 999. Thus, the court will not consider any delay in entry of the Consent Decree because the intervenors oppose its entry as presenting any bar to intervention. Furthermore, in the present case, the delay between filing of the motion to intervene and the district court’s consideration of it was almost as long as the delay between the filing of the lawsuit and the filing of the motion to intervene. The litigation had progressed little between the time it was filed and the time the non-settling PRPs moved to intervene, and it was not until three months later that the EPA moved the court for entry of the Consent Decree. Id. (proceedings were still at preliminary stage and little progress had occurred at time of motion to intervene). The motion to intervene was therefore timely, and this court will pass on to other factors in the Rule 24 intervention analysis.
2. Intervention Pursuant To Statutory Right
Fed.R.Civ.P. 24(a) provides for intervention as of right, in the first instance, “when a statute of the United States confers an unconditional right to intervene.” Although the non-settling PRPs assert that they had a statutory right to intervene pursuant to CERCLA § 113(i), the court does not under
3. Intervention Pursuant To Fed. R.Civ.P. 24(a)(2)
This court has, upon more than one occasion, stated that, besides timely application, the applicant for intervention must satisfy a tripartite test in order to intervene pursuant to Fed.R.Civ.P. 24(a)(2):
1) the party must have a recognized interest in the subject matter of the litigation; 2) that interest must be one that might be impaired by the disposition of the litigation; and 3) the interest must not be adequately protected by the existing parties.
Mille Lacs,
a. Interest And Impairment Of Interest
“Recognized interest.” Although in Mille Lacs and Planned Parenthood, this court defined an interest sufficient to support intervention as “a recognized interest in the subject matter of the litigation,” the courts of appeals of other circuits have stated that intervention requires that the intervenor have an interest in the proceedings that is “direct, substantial, and legally protectable.” Alameda Water & Sanitation Dist. v. Browner,
In Mille Lacs, this court found a “recognized interest in the subject matter of the litigation” on the part of the applicants for intervention, because the litigation involved the rights of a band of Indians to use property owned by the applicants, and the applicants had an interest in protecting then-property values. Mille Lacs,
Impairment of the interest. The second factor of the Mille Lacs analysis is whether the interest of the applicant for intervention is one that might be impaired by the disposition of the litigation. Mille Lacs,
In Mille Lacs, the court found that a settlement favorable to the Indian Band might have impaired the recognized interests of the applicants for intervention, because it might have permitted Band members to exercise treaty rights upon the proposed intervenors’ land, thereby affecting property values. Mille Lacs,
“Contingent” interests. Questions of the adequacy of an interest and its potential for impairment may overlap in cases in which the interest is in some way “contingent.” Although the intervenor cannot rely on an interest that is wholly remote and speculative, the intervention may be based on an interest that is contingent upon the outcome of the litigation. Jenkins by Agyei v. Missouri,
[t]he rule does not require, after all, that appellants demonstrate to a certainty that their interests will be impaired in the ongoing action. It requires only that they show that the disposition of the action ‘may as a practical matter’ impair their interests.
Little Rock Sch. Dist.,
Other circuit courts of appeals have similar standards concerning purportedly “speculative” claims. For example, in Sierra Club v. Espy,
The “contingency” of contribution claims under CERCLA Whether an interest in contribution claims is sufficiently pro-tectable, rather than excessively “speculative” or “contingent,” to support intervention in an action under CERCLA has concerned a remarkably small number of courts in view of the statutory authority to intervene in CERCLA actions. Nonetheless, the small group of resulting decisions has produced a split on the issue. In United States v. Alcan
When a PRP settles with the government it accepts a specific liability. Unlike the interest of an applicant who has not yet settled, which is contingent in the sense that it may never ripen, the interest of an applicant who has already settled is contingent only in the sense that it cannot be valued. However, the fact that the interest cannot be valued does not mean it does not exist. The act of settling transforms a PRP’s contribution right from a contingency to a mature, legally protectable interest.
Id. Although it had earlier rejected reliance on legislative history, id. at 1181, the court then considered legislative intent as supporting this conclusion, finding that Congress intended non-settling PRPs to be “expos[ed] ... to liability for the rest of the cleanup cost even if that exposure exceeds the amount the non-settlor’s actions added to the overall cost of the cleanup.” Id. at 1184 (citing United States v. Cannons Eng’g Corp.,
Earlier decisions of district courts, however, in which non-settlors sought intervention, foEowed much the same reasoning as was stated by the Third Circuit Court of Appeals in Alcan, looking to legislative history and policy, to conclude that non-settling PRPs did not have a legally protectable interest in contribution claims to intervene in litigation between the government and settling PRPs to enforce a consent decree. See United States v. ABC Indus.,
Against the clamor of this authority is heard a lone voice declaring that a different result is proper. In United States v. Acton Corp.,
[T]he Court need not consider the legislative history of the CERCLA provisions, as the statute’s terms are unambiguous. See United States v. Ron Pair Enterprises, Inc.,489 U.S. 235 , 240,109 S.Ct. 1026 , 1030,103 L.Ed.2d 290 (1989); Malloy v. Eichler,860 F.2d 1179 , 1183 (3d Cir.1988). Section 113(i) gives the intervention rights to “any person” who satisfies the section’s requirements. Accordingly, the Government’s argument [that legislative intent indicated dissatisfied non-settlors should not be allowed to intervene in order to challenge entry of a CERCLA consent decree] will be disregarded.
Id. The court then applied the four requirements for intervention as of right — timeliness, existence of a protected interest, impairment of that interest, and lack of representation by an existing party — found in both Rule 24(a)(2) and CERCLA § 113(i). Id. The court found the central issue in its inquiry, as in ours, to be whether the applicants had a protectable interest in either contribution or the fairness of the proposed consent decree. Id.
As to the protectability of the interest, the Acton court first concluded that the interest of the intervenors in contribution claims was neither merely economic nor so contingent as to be unprotectable. Id. The court found that the interest was statutory and would be extinguished if the consent decree was entered, and therefore was legally protectable. Id. The court then rejected the argument that the interest was contingent. Id. at 434. The court concluded that none of the identified contingencies go to the existence of the right itself. Id. The court also found that the government’s position would vitiate the right to contribution in § 113(f)(1), because, under the government’s conception, non-settling PRPs could not seek contribution against PRPs who had signed an unapproved consent decree, because the interest was only contingent, but the right would be cut off as soon as the consent decree was approved. Id. Finally, the court rejected the notion that participation in negotiations or notice and comment proceedings before the drafting of the settlement agreement substituted for adequate representation in the litigation by an existing party. Id. at 436. The court found that whatever the non-settlors’ representation in those prior proceedings had been, there was no existing party representing those parties in the current litigation. Id.
b. Sufficiency of the interest here
In this case, we feel compelled to follow the more cogent reasoning of the minority position. We hold that the prospective inter-venors here had both a recognized interest in
Policy and legislative history. We noted above our disapproval of the district court’s reliance primarily on policy arguments instead of on the factors that should be considered in determining whether intervention should be allowed under Fed.R.Civ.P. 24(a)(2) and § 113(i). Accord In re Sierra Club,
When the language of the statute is plain, the inquiry also ends with the language of the statute, for in such instances “the sole function of the courts is to enforce [the statute] according to its terms.” Ron Pair,
Here, CERCLA’s intervention provisions unambiguously provide for intervention by “any person” when such person meets the requirements of the statute. CERCLA § 113(i), 42 U.S.C. § 9613(i); Acton,
Our rejection of legislative intent and policy as the primary considerations in the analysis of whether or not to permit intervention under § 113(i), of course, puts us at odds with the majority of courts to decide the issue. Nonetheless, we find reliance for a determination of intervention solely on the basis of the factors identified in § 113(i) to be the appropriate course, because we are to apply the factors identified by Congress. Germain,
Recognized interest. Turning therefore to consideration of the factors identified in both § 113(i) and Rule 24(a)(2), we consider first whether the applicants here have “an interest relating to the subject of the action.” CERCLA § 113(i), 42 U.S.C. § 9613(i); FedR.Civ.P. 24(a)(2). The non-settling PRPs’ interest was created by provisions of the precise statute under which the litigation was brought. CERCLA § 113(f)(1), 42 U.S.C. § 9613(f)(1), provides for the right of contribution as follows:
(f) Contribution
(1) Contribution
Any person may seek contribution from any other person who is liable or potentially liable under section 9607(a) of this title, during or following any civil action under section 9606 of this title or under section 9607(a) of this title. Such claims shall be brought in accordance with this section and the Federal Rules of Civil Procedure, and shall be governed by Federal law. In resolving contribution claims, the court may allocate response costs among liable parties using such equitable factors as the court determines are appropriate. Nothing in this subsection shall diminish the right of any person to bring an action for contribution in the absence of a civil action under section 9606 or section 9607 of this title.
CERCLA § 113(f)(1), 42 U.S.C. § 9613(f)(1). This litigation has been brought pursuant to 42 U.S.C. §§ 9606 and 9607, and the settling PRPs and the non-settling PRPs seeking to intervene are all persons who are or are potentially liable in this action. The contribution interest created by § 113(f)(1) is directly related to the subject matter of the litigation, because it may be asserted “during or following” that litigation, and arises from the liability or potential liability of persons as the result of that litigation. CERCLA § 113(f)(1), 42 U.S.C. § 9613(f)(1); Mille Lacs,
Contrary to the arguments of the EPA and settling PRPs here, it is precisely because § 113(f)(2) would cut off the interest estab
We find the conclusion that the contribution interest is “speculative” or “too contingent” to support intervention to be wrong in law. The interest does not arise only after the daisy-chain of events identified here by the EPA and settling PRPs and in other decisions by other courts as including litigation against the prospective intervenors, a finding of liability against them, and assessment of excessive liability. Rather, under the terms of § 113(f)(1) itself, the interest arises at any time during or following litigation pursuant to § 106 or § 107 between persons who are or are 'potentially hable. CERCLA § 113(f)(1), 42 U.S.C. § 9613(f)(1). Thus, no finding of liability is required, nor assessment of excessive liability, before the contribution interest arises. Only the recovery on a contribution claim must await the outcome of this or further litigation, not the right to bring such a claim. Even were it true that the contribution interest is somehow contingent upon further litigation, either to determine its monetary value or whether it indeed vests or the actual extent of any impairment, that “contingency” alone would not bar intervention. Jenkins by Agyei
Impairment. Certainly, the contribution interest of the prospective intervenors may as a practical matter be impaired by the present litigation. Fed.R.Civ.P. 24(a)(2); Kansas Pub. Employees Retirement Sys.,
(2) Settlement
A person who has resolved its liability to the United States or a State in an administrative or judicially approved settlement shall not be hable for claims for contribution regarding matters addressed in the settlement. Such settlement does not discharge any of the other potentially Hable persons unless its terms so provide, but it reduces the potential liability of the others by the amount of the settlement.
CERCLA § 1113(f)(2), 42 U.S.C. § 9613(f)(2). Thus, disposition of the present litigation could bar or reduce the monetary value of the contribution claims of the prospective intervenors against the settling PRPs. See Mille Lacs,
c. Inadequate Representation By Existing Party
The third requirement for intervention is that the interest must not be adequately protected by the existing parties. Mille Lacs,
Although the burden to show inadequate representation is generally “minimal,” this court has recognized that the applicant for intervention bears a heavier burden on this factor when a party already in the suit has an obligation to represent the interests of the party seeking to intervene. Mille Lacs,
Even where such a presumption of adequate representation arises on this basis, however, it may be rebutted by a showing that the applicant’s interest cannot be subsumed within the shared interest of the citizens of the state. Id. at 1000-1001 (citing Dimond v. District of Columbia,
on the other hand, [was] seeking to protect a more narrow and “parochial” financial interest not shared by the citizens of the District of Columbia. The District would be shirking its duty were it to advance this narrower interest at the expense of its representation of the general public interest. Since [the insurance company’s] interest cannot be subsumed within the shared interest of the citizens of the District of Columbia, no presumption exists that the District will adequately represent its interests.
Id. (citations omitted). This court found that the presumption did not apply in Mille Lacs, because the applicants to intervene, certain counties, owned some property outright from which they derived specific benefits, and that these interests were narrower than and not subsumed by the general interest of the State of Minnesota in protecting fish and game. Mille Lacs,
The EPA and the settling PRPs appear to argue that the non-settling PRPs’ interests have been adequately protected in the present litigation, because of the extensive negotiations and public comment procedures that preceded the drafting of the Consent Decree the EPA seeks to impose in this litigation. The suggestion that the interve-nors had the opportunity to protect their interests in the comment procedures prior to filing of the proposed Consent Decree simply misses the point. The question is not whether the intervenors had any other way of protecting their interests, but whether those interests are protected in this litigation. Fed.R.Civ.P. 24(a)(2); Mille Lacs,
The court must compare the interests of proposed intervenors with the interests of current parties. Kansas Pub. Employees Retirement Sys.,
Nor can it be argued here that the EPA, either through its comment procedures or by its participation in this litigation, is a representative of the sovereign who will adequately represent the interests of the non-settling PRPs as citizens. Here, the interests of the prospective intervenors cannot be subsumed within the shared interest of the citizens of the United States. Mills Lacs,
The non-settling PRPs therefore meet the requirements for intervention as of right articulated in both Rule 24(a)(2) and CERCLA § 113(i). We hold that the district court erred in denying the non-settling PRPs’ motion to intervene.
B. Permissive Intervention
The non-settling PRPs also sought, and the district court denied, permissive intervention pursuant to FedR.Civ.P. 24(b).
CONCLUSION
There being no adequate representatives of the prospective intervenors’ legally pro-tectable interests among the existing parties to this litigation, we hold that the prospective intervenors were entitled to intervene as of right pursuant to FedR.Civ.P. 24(a)(2). The district court erred when it denied interven
We reverse and remand for withdrawal of approval of the Consent Decree and for grant of the non-settling PRPs’ motion for leave to intervene.
Notes
. In In re Sierra Club,
The district court, however, incorrectly bolstered its denial of intervention of right by referring to concerns of judicial economy and need for guidance. Although those issues have a place in motions for permissive intervention, Rule 24(a) affords them no weight.
In re Sierra Club,
. This is the one element of the district court's determination of a motion for intervention that is reviewed for abuse of discretion. Kansas Pub. Employees Retirement Sys.,
. Nor does § 113(i) establish the sort of “unqualified” right to intervene held to be ''unconditional” under Fed.R.Civ.P. 24(a)(1). See, e.g., Phar-Mor, Inc. v. Coopers & Lybrand,
. The Alcan court found the decision in Browning-Ferris unsound, because § 113(f)(3)(C) does not affect contribution rights. Alcan,
. The Fifth Circuit Court of Appeals defines a "direct, substantial, legally protectable interest in the action” required by Rule 24(a) as an interest that "the substantive law recognizes as belonging to or being owned by the applicant." Cajun Elec. Power Co-op. v. Gulf States Utils.,
. The Fourth Circuit Court of Appeals remarked that “[w]hether an interest contingent upon the outcome of other pending litigation constitutes a ‘significantly protectable interest' has been the source of much disagreement." Teague v. Bakker,
[s]ome courts have concluded that an interve-nor must demonstrate more than "a mere provable claim” in order to be entitled to intervention of right, see Independent Petrochemical
Id. (emphasis added). In the present case, we find that the prospective intervenors also stand to gain or lose by the direct legal operation of the consent decree, which would subject their contribution claims to the bar found in § 113(f)(2), 42 U.S.C. § 9613(f)(2).
. The district court below did not consider whether the interests of the prospective interve-nors were adequately protected in the present litigation, because that court found the prospective intervenors had no interest to protect. However, because we conclude that the prospective intervenors have protectable interests, we must consider the question of whether the identified interests are adequately protected by an existing party. Furthermore, § 113(i) places upon the EPA the burden of showing that the interests of the intervenors were already protected by existing parties. As is discussed below, the EPA cannot carry this burden.
. The presumption of adequate representation by an existing parly may arise in situations not involving an existing governmental party. The relationship between the existing party and the party seeking to intervene may involve duties each owes the other that are similar to the duties of a governmental entity to protect the interests of its citizens. For example, this court has held that an insured may adequately represent the subrogation interests of its insurer even where the insurer might have additional claims that it would want to pursue in separate litigation if the insured were successful on the initial claim. St. Paul Fire & Marine Ins. v. Helena Marine Serv.,
. Fed.R.Civ.P. 24(b) states, in pertinent part, that permissive intervention may be allowed
(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.
The grant or denial of permissive intervention is in the discretion of the trial court. Siena Club v. Robertson,
