After the Illinois Environmental Protection Agency issued a permit authorizing Indeck-Elwood LLC to construct a 660-megawatt coal-fired power plant in Elwood, Illinois, the Sierra Club filed a petition for review naming the United States Environmental Protection Agency as the sole respondent—even though it has taken no action in response to the state’s decision. Cf.
Alaska Department of Environmental Conservation v. EPA,
— U.S. -,
Rule 15(d) does not provide standards for intervention, so appellate courts
*518
have turned to the rules governing intervention in the district courts under Fed. R.Civ.P. 24. See
Automobile Workers v. Scofield,
The Chamber, by contrast, lacks any direct interest in the outcome. Rule 24(a)(2) provides that, unless a statute governs (and none does so here), intervention is proper “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.” The Chamber does not have “an interest relating to the property or transaction which is the subject of the' action”; its concern is not a
legal
“interest” (the permit at stake affects only one power plant) but a political or programmatic one: the Chamber favors more business and less environmental regulation. That does not justify intervention. Indeed, it does not necessarily justify even a filing as
amicus curiae.
Courts value submissions not to see how the interest groups line up, but to learn about facts and legal perspectives that the litigants have not adequately developed. See
National Organization for Women, Inc. v. Scheidler,
Even if the Chamber had a legal interest to protect, it could not intervene as long as that interest is “adequately represented by existing parties.” Indeck-ElWood will defend the state agency’s decision, and the federal EPA is likely to do so. The Chamber says that it fears that the parties will settle the proceeding, but this is a reason to deny rather than allow intervention. Why should the Chamber receive an entitlement to nix a settlement (if one can be reached) that the Sierra Club, Indeck-Elwood, and the EPA all favor? Officious intermeddlers ought not be allowed to hijack litigation that the real parties in interest can resolve to mutual benefit.
According to the Chamber, two courts of appeals — this circuit plus the D.C. Circuit — have permitted it to intervene in litigation against the EPA. None of these decisions provides an explanation, and none is published, so they have no prece-dential force. For all we can tell, in those cases the Chamber represented a member that would have been allowed to intervene on its own behalf. Moreover, associations that could have filed their own petitions for *519 review of regulations that affect their members may be able to intervene if someone else beats them to the punch. It is unnecessary for us to speculate about why intervention was allowed on those other occasions. Neither the Chamber nor any of its members would have been entitled to file a petition to review either the Illinois agency’s decision to grant a permit or the inter-agency correspondence in question. When the time comes, the Chamber may seek leave to participate as amicus curiae; it is not entitled to participate as a party and its motion to intervene is denied.
