See FED. R. APP. P. 43(c)(2). 2 No. 20-3325 Before SYKES, Chief Judge, and FLAUM and ROVNER, Circuit Judges. SYKES, Chief Judge. This appeal is another chapter in con- current federal and state litigation challenging the construc- tion of a $500 million, 100-mile power line in southwestern Wisconsin. In September 2019 the Public Service Commis- sion of Wisconsin issued a permit authorizing two transmis- sion companies and an electricity cooperative to build and operate the line. A few months later, two environmental groups filed lawsuits in both federal and state court seeking to invalidate the permit. As relevant here, the parallel suits allege that two of the three commissioners had disqualifying conflicts of interest and should have recused themselves. Both suits raise federal due-process claims; the state litiga- tion also invokes state recusal law and contests the permit on other state-law grounds. The case was last here at an early stage of the proceed- ings when the district judge rejected the permit holders’ motion to intervene. We reversed that decision and remand- ed with instructions to grant the intervention motion. Driftless Area Land Conservancy v. Huebsch (“Driftless I”), 969 F.3d 742 (7th Cir. 2020). Rulings on dismissal motions followed, and the judge significantly narrowed the scope of the case. But he denied the commissioners’ motion to dismiss based on sovereign immunity. The case returns to us on that issue. The commissioners have been sued in their official capac- ities, so sovereign immunity blocks this suit in its entirety unless it falls within the Ex parte Young exception, which authorizes a federal suit against state officials for the pur- pose of obtaining prospective relief against an ongoing No. 20-3325 3 violation of federal law. The environmental groups seek an order vacating the permit or enjoining its enforcement; the latter is prospective relief. The harder question is whether the suit challenges an ongoing violation of federal law. The alleged due-process violation occurred (if at all) in Septem- ber 2019 when the commissioners approved the permit. The environmental groups contend that the violation is ongoing as long as the permit remains in force and effect and the commissioners have the power to enforce, modify, or rescind it. Though there is little precedent precisely on point for a claim like this one, we hold that Ex parte Young applies and therefore agree with the judge’s ruling on sovereign immuni- ty. The commissioners also moved for abstention under Colorado River Water Conservation District v. United States, 424 U.S. 800, 818 (1976), which authorizes a federal court to abstain from exercising jurisdiction and stay a case to await the outcome of parallel state litigation when there is a sub- stantial likelihood that the state case will resolve the federal claim. The judge denied the request, reasoning that the federal and state suits are not parallel because the state case doesn’t raise a federal due-process claim. That was an error; as we’ve noted, both cases raise federal due-process claims. Although the abstention ruling is not before us, we may raise abstention sua sponte and do so here. The state and federal suits are clearly parallel for purpos- es of Colorado River. The environmental groups have raised materially identical due-process recusal claims in both state and federal court. Given the context—this case implicates serious state interests regarding the operation of Wisconsin administrative law and judicial review of state-agency 4 No. 20-3325 proceedings—it’s appropriate to abstain from exercising federal jurisdiction to give the state courts an opportunity to decide the recusal issue. Litigating the same conflict-of- interest questions in both court systems is duplicative and wasteful; comity and the sound administration of judicial resources warrant abstention under Colorado River. We remand with instructions to stay the case pending resolution of the state proceedings. I. Background The underlying administrative proceedings are complex, but the details are largely unimportant here. What’s needed is a basic understanding of the state regulatory framework and the background of the federal and state litigation. We assume familiarity with Driftless I and will be as brief as possible, but some length cannot be avoided. The plaintiffs are two Wisconsin environmental groups, Driftless Area Land Conservancy and the Wisconsin Wildlife Federation. They sued the Public Service Commission of Wisconsin and its three commissioners—Rebecca Valcq, Michael Huebsch, and Ellen Nowak. The intervenors are the utility companies that hold the permit and will own and operate the power line: American Transmission Company LLC, ITC Midwest LLC, and Dairyland Power Cooperative (we refer to them collectively as “the transmission compa- nies”). To place the sovereign-immunity and abstention issues in context, some background about the regulatory scheme is necessary. The Commission “has jurisdiction to supervise and regulate every public utility” in Wisconsin. WIS. STAT. § 196.02(1). Its three commissioners are appointed by the No. 20-3325 5 governor and confirmed by the state senate. One of the Commission’s many duties is to regulate the construction of high-voltage electricity transmission lines. Id. § 196.491(1)(e), (3). With one irrelevant exception, transmission lines may be constructed only if the Commission grants a permit known as a “certificate of public convenience and necessity.” Id. § 196.491(3)(a)1. Although a permit is a prerequisite for projects that require the use of eminent domain, the Commission itself does not condemn the land needed for construction. Rather, state law transfers the state’s eminent- domain power to the utility once the permit has been ap- proved. Id. § 32.02. That is, a utility company holding an approved permit may use the condemnation power to acquire the land needed to complete an approved project. The permitting process is complex. The Commission may grant a permit only if the transmission line is “in the public interest.” Id. § 196.491(3)(d)3. An application commences a highly technical inquiry. The Commission must consider a multitude of factors such as the reliability of the power supply, alternative sources of supply, economic factors, engineering obstacles, safety, and environmental impact. Id. The Commission’s role continues after it issues a permit. The enabling statute is expansive and gives the Commission sweeping jurisdiction to “supervise and regulate every public utility in this state and to do all things necessary and convenient to its jurisdiction.” Id. § 196.02(1). This includes the power to file lawsuits, id. § 196.02(12), and to “rescind, alter[,] or amend” a permit at any time, id. § 196.39(1). The Commission also coordinates with the Midcontinent Independent System Operator (“MISO”), a regional trans- mission organization that operates interstate electricity grids 6 No. 20-3325 on behalf of its constituent utility companies. 1 MISO must involve the Commission in all grid-expansion activities. See 18 C.F.R. § 35.34(k)(7). In order to coordinate with MISO, the Commission delegates to one commissioner the authority to represent it before MISO’s Advisory Committee and the Board of the Organization of MISO States, a group that represents the interests of state regulators. Commissioner Huebsch was the Commission’s designated MISO repre- sentative during the relevant period, and he also served as secretary of the Organization of MISO States. The events giving rise to the parallel state and federal lit- igation began in April 2018 when the transmission compa- nies applied for a permit to construct a 100-mile, high- voltage power line stretching from Dane County in south- central Wisconsin to Dubuque County in eastern Iowa. At a projected cost of about $500 million, the power line would serve the electricity needs of consumers in the southwestern quadrant of the state. The application required the Commis- sion to convene a class 1 “contested case” proceeding under state administrative law. WIS. STAT. § 227.01(3)(a). More than 50 parties intervened, including Driftless and the Wildlife Federation. On behalf of themselves and their members, they opposed the project based on environmental and land-use impacts. After extensive proceedings and submissions, on August 20, 2019, the Commission held an open meeting and 1 A regional transmission organization is a voluntary association of utility companies that operates electrical grids on behalf of the utilities. See Ill. Com. Comm’n v. Fed. Energy Regul. Comm’n, 721 F.3d 764, 769 (7th Cir. 2013). No. 20-3325 7 unanimously voted to conditionally grant the permit. A month later the two environmental groups moved to dis- qualify Commissioners Valcq and Huebsch based on alleged conflicts of interest. On September 26, 2019, the Commission issued a 112-page order finalizing and approving the permit. The order addressed and rejected the recusal motion as untimely, procedurally improper, and lacking a “factual basis to support recusal.” On December 11 Driftless and the Wildlife Federation sued the Commission and the commissioners in federal court in the Western District of Wisconsin seeking to invali- date the permit. Two days later they filed two suits in state court seeking the same relief under Chapter 227 of the Wisconsin Statutes, which authorizes judicial review of state administrative proceedings. See id. § 227.53. Within days they intervened in a third judicial-review lawsuit filed by another party. (From now on we refer to the two environ- mental groups collectively as “Driftless.”) The federal suit raises due-process and takings claims under 42 U.S.C. § 1983. The first two counts center on allega- tions that Commissioners Valcq and Huebsch had disquali- fying conflicts of interest that required them to recuse themselves from the permit proceeding. Count One alleges a violation of due process. Count Two, styled as a violation of “Due Process and Eminent Domain,” simply repackages the due-process claim as an unconstitutional taking of private property. This count adds nothing of legal significance; allegations of adjudicator bias implicate the Due Process Clause, not the Takings Clause, so Count Two can be ig- nored. Count Three, a true Takings Clause claim, alleges that 8 No. 20-3325 the permit authorizes an unconstitutional taking of private property for private use. The conflict-of-interest allegations against Commissioner Valcq stem from her career in the private sector. Prior to her service on the Commission, Valcq was employed as in-house and outside counsel for We Energies Corp. The parent company of We Energies owns a 60% interest in American Transmission Company, one of the permit applicants. The conflict-of-interest allegations against Huebsch center on his representation of the Commission on MISO, which inter- vened in the permit proceedings in support of the project. The complaint also accuses him of engaging in ex parte communications with MISO representatives and other interested parties. The state lawsuits—including a fourth judicial-review action—were consolidated in Dane County Circuit Court, and the combined litigation raises a federal due-process claim based on the same conflict-of-interest allegations involving Commissioners Valcq and Huebsch. The state litigation also invokes the right to an impartial adjudicator under state law and raises unrelated violations of state administrative and environmental law. The opening act in the federal suit involved a disagree- ment over the transmission companies’ right to intervene. Our August 2020 decision in Driftless I authorized their intervention, and on remand the case proceeded to decision on a bevy of dismissal arguments. As relevant here, the Commission, the commissioners, and the transmission companies moved to dismiss the complaint based on sover- eign immunity and the failure to state any cognizable consti- tutional claim. Alternatively, they urged the judge to abstain No. 20-3325 9 from exercising jurisdiction and stay the case based on the ongoing state litigation, citing both Younger v. Harris, 401 U.S. 37 (1971), and Colorado River. In November 2020 the judge issued a lengthy decision dismissing the case in part and substantially trimming its scope. First, he dismissed the case against the Commission itself, explaining that state agencies, as arms of the state, enjoy sovereign immunity from suit in federal court under the Eleventh Amendment. Indeed, Driftless conceded its mistake in suing the Commission and agreed that it must be dismissed from the suit. The commissioners’ immunity claim, however, was another matter; it was hotly contested. State officials may be sued in federal court in their official capacities notwithstanding the state’s sovereign immunity if the Ex parte Young exception applies. Under that doctrine a plaintiff may proceed in federal court against a state official for the limited purpose of obtaining prospective relief against an ongoing violation of federal law. The judge concluded that Ex parte Young applies and declined to dis- miss the suit against the commissioners on immunity grounds. The judge also denied the abstention request, ruling that Younger abstention is inapplicable because the state case doesn’t fit within the limited categories of cases covered by the doctrine. He also ruled out Colorado River abstention. He reasoned that the federal and state cases are not parallel in the sense meant by Colorado River because the state litigation does not raise a federal constitutional claim (or so he thought, mistakenly). 10 No. 20-3325 Moving on to the arguments on the merits, the judge dismissed Count Three—the takings claim—for failure to state a claim. Under the broad contours of the Supreme Court’s Takings Clause cases, see, e.g., Kelo v. City of New London, 545 U.S. 469, 478–82 (2005), that claim is not remote- ly plausible. As the judge explained, construction of a power line is universally recognized as a constitutionally permissi- ble public purpose for using eminent domain. That left only the due-process claim based on the conflict- of-interest allegations involving Commissioners Valcq and Huebsch. The judge concluded that the conflict allegations against them cleared the plausibility bar under the due- process standard announced in Caperton v. A.T. Massey Coal Co., 556 U.S. 868 (2009). But nothing in the complaint sug- gests that Commissioner Nowak had a conflict of interest, so the judge dismissed the case against her. The judge’s sovereign-immunity ruling precipitated this appeal. An order denying a claim of sovereign immunity is immediately appealable, Richman v. Sheahan, 270 F.3d 430, 434 (7th Cir. 2001), so Valcq and Huebsch—the remaining defendants—appealed the denial of their motion to dismiss on immunity grounds. A stay is customary in this situation, Allman v. Smith, 764 F.3d 682, 684 (7th Cir. 2014), so we stayed the proceedings in the district court while the im- munity appeal is pending. On August 26, 2021, Driftless moved to partially lift the stay. We address that motion below. II. Discussion We begin with an oddity in the case that complicates the analysis of sovereign immunity and the Ex parte Young No. 20-3325 11 exception. Huebsch resigned from the Commission in February 2020, shortly after the suit was filed and long before the judge ruled on the motion to dismiss. Inexplica- bly, he remains a defendant in this official-capacity suit even though he is out of office and no relief can be ordered against him. Under Rule 25(d) of the Federal Rules of Civil Procedure, when a public officer is sued in his official capac- ity and resigns from office while the suit is pending, his successor is automatically substituted. Tyler Huebner suc- ceeded Heubsch in March 2020, but the substitution did not occur. As the case comes to us, then, Valcq is the only defendant against whom an injunction could possibly issue. And that raises an anomaly in the district court’s Ex parte Young analysis. An injunction against Valcq—one member of a three-member commission—would be pointless. We can fix the problem by applying Rule 43(c)(2) of the Federal Rules of Appellate Procedure, which like Rule 25(d) requires the substitution of the current officeholder. We therefore substi- tute Commissioner Huebner for Huebsch. But that’s not the only complication. There are notable gaps in the information we’ve received from the parties about the status of the concurrent state proceedings. While this appeal has been pending, significant developments have occurred in the state litigation. The parties alerted us to this information only very recently in their briefs supporting and opposing the August 26 motion to partially lift the stay. Even then, however, they omitted some important details. Here’s what we’ve pieced together from the public record and the parties’ filings on the motion to lift the stay. On January 21, 2021—a month before this appeal was argued— 12 No. 20-3325 the judge presiding in the consolidated judicial-review proceedings in Dane County held a lengthy hearing and ruled that Commissioner Valcq’s prior representation of We Energies was not a disqualifying conflict of interest and did not trigger a due-process duty to recuse. The judge accord- ingly rejected Driftless’s request for discovery on those allegations and said he was “throwing out any challenge to Commissioner Valcq.” Hearing Transcript (Jan. 21, 2021), Affidavit of Brian H. Potts in Response to Motion to Lift Stay, Ex. 2 at 77, No. 20-3325, ECF No. 64-2. The judge reached the opposite conclusion regarding Huebsch, ruling that the conflict-of-interest allegations against him were enough to state a prima facie case of an appearance of improper bias. Id. at 77–79. The judge therefore authorized discovery on the recusal question involving Huebsch and directed the parties to propose a discovery plan. They did so. On May 25 the judge issued a written order memorializing his oral rulings and setting a discovery schedule. County of Dane v. Pub. Serv. Comm’n of Wis., No. 2019CV003418 (Wis. Cir. Ct. Dane Cnty. May 25, 2021) (decision and order). Some procedural skirmishes ensued, and by July the liti- gation over Huebsch’s alleged conflict of interest had moved to the court of appeals. More procedural maneuvering followed, and by the end of the summer, the case landed at the Wisconsin Supreme Court’s doorstep. On September 21 the state high court granted Huebsch’s petition for expedited review and set a briefing schedule. County of Dane v. Pub. Serv. Comm’n of Wis., No. 2021AP1321-LV (Wis. Sept. 21, 2021) (order granting expedited review). The petition raises threshold procedural questions and several substantive questions about the legal standards for evaluating recusal issues under Caperton and state law and the proper applica- No. 20-3325 13 tion of those standards to the allegations involving Huebsch. The Dane County proceedings are stayed while the case is pending before the state supreme court. 2 There is more. On June 28 the transmission companies returned to the Commission and asked it to reopen the permit proceedings on its own motion to rescind and recon- sider the permit based on the conflict-of-interest allegations regarding Heubsch. On July 1 the Commission issued a notice of intent to rescind the permit and invited comments by July 19. Notice of Intent and Request for Comments, Cardinal-Hickory Creek Project, Pub. Serv. Comm’n of Wis., No. 5-CE-146, Ref# 415003 (July 1, 2021), https://apps.psc. wi.gov/ERF/ERFview/viewdoc.aspx?docid=415003. A hear- ing was held on July 29; the minutes reflect that the Com- mission discussed the matter but took no action. Id., Minutes and Informal Instructions of the Open Meeting of Thursday, July 29, 2021, Ref# 418174 (Aug. 5, 2021), https://apps.psc.wi. gov/ERF/ERFview/viewdoc.aspx?docid=418174. As best we can tell, that’s where things stand in the state courts and before the Commission. These important devel- opments inform the abstention inquiry, to which we’ll turn in a moment. But sovereign immunity is our first issue. It is a 2 Yesterday Driftless notified us of additional events in the state case. On October 8 Driftless filed an emergency motion for injunctive relief blocking construction activity—the same relief it wanted to pursue in the district court if its motion to lift the stay in this case were successful. On October 12 the Dane County judge stayed the proceedings pending a decision by the Wisconsin Supreme Court, but on October 18 he nonethe- less held a telephonic hearing on the emergency motion and orally granted it. The docket reflects that he is currently considering a motion to stay his order pending appeal. 14 No. 20-3325 jurisdictional defense. See, e.g., Gorka v. Sullivan, 82 F.3d 772, 774 (7th Cir. 1996) (describing sovereign immunity as a “jurisdictional bar”); Crosetto v. State Bar of Wis., 12 F.3d 1396, 1400 (7th Cir. 1993) (labeling “state sovereign immunity” as “one of the Constitution[’s] unavoidable jurisdictional hurdles”). A. Sovereign Immunity “Sovereign immunity is the privilege of the sovereign not to be sued without its consent” and is secured to the states by the Eleventh Amendment. Va. Off. for Prot. & Advoc. v. Stewart, 563 U.S. 247, 253 (2011). As the Supreme Court has explained, the Eleventh Amendment “confirm[s] the struc- tural understanding that States entered the Union with their sovereign immunity intact, unlimited by Article III’s juris- dictional grant.” Id. The text of the Amendment provides: “The Judicial pow- er of the United States shall not be construed to extend to any suit in law or equity, commenced or prosecuted against one of the United States by Citizens of another State.” U.S. CONST. amend. XI. Although this language does not “by its terms … bar suits against a State by its own citizens,” the Supreme Court “has consistently held that an unconsenting State is immune from suits brought in federal courts by her own citizens as well as by citizens of another State.” Edelman v. Jordan, 415 U.S. 651, 662–63 (1974). “[I]f properly raised, the [A]mendment bars actions in federal court against a state, state agencies, or state officials acting in their official capacities.” Council 31 Am. Fed’n of State, Cnty. & Mun. Emps. v. Quinn, 680 F.3d 875, 881 (7th Cir. 2012) (quotation marks omitted). No. 20-3325 15 But “sovereign immunity is not absolute immunity.” Id. at 882. The doctrine of Ex parte Young, 209 U.S. 123 (1908), creates an exception to state sovereign immunity “by assert- ing that a suit challenging the constitutionality of a state official’s action in enforcing state law is not one against the State.” Green v. Mansour, 474 U.S. 64, 68 (1985). The doctrine is “accepted as necessary to permit the federal courts to vindicate federal rights.” Stewart, 563 U.S. at 254–55 (quota- tion marks omitted). “It rests on the premise—less delicately called a ‘fiction’—that when a federal court commands a state official to do nothing more than refrain from violating federal law, he is not the State for sovereign-immunity purposes.” Id. at 255 (cleaned up). But Ex parte Young is “limited to that precise situation.” Id. It applies only when a plaintiff seeks prospective relief against an ongoing violation of federal law. Idaho v. Coeur d’Alene Tribe of Idaho, 521 U.S. 261, 281 (1997). Accordingly, our task is to “conduct a straightforward inquiry into whether [the plaintiffs’] complaint alleges an ongoing viola- tion of federal law and seeks relief properly characterized as prospective.” Verizon Md., Inc. v. Pub. Serv. Comm’n of Md., 535 U.S. 635, 645 (2002) (quotation marks omitted). 1. Prospective Relief Analyzing the form of relief is the simpler part of the in- quiry. Injunctive relief is prospective relief. See Coeur d’Alene, 521 U.S. at 277 (“[W]e have consistently allowed suits seek- ing prospective injunctive relief based on federal violations to proceed.”); Hutto v. Finney, 437 U.S. 678, 690 (1978) (“[S]tate officers are not immune from prospective injunctive relief.”); Edelman, 415 U.S. at 664 (“[T]he relief awarded in Ex parte Young was prospective only; the Attorney General of 16 No. 20-3325 Minnesota was enjoined to conform his future conduct of that office to the requirement of the Fourteenth Amend- ment.”). It’s usually easy to separate suits for prospective relief from those that seek retroactive remedies; the latter primarily take the form of monetary damages to remedy past harms. See McDonough Assocs. v. Grunloh, 722 F.3d 1043, 1050–51 (7th Cir. 2013) (explaining that courts cannot “direct a state to make payments … to remedy a past injury to a private party”); MSA Realty Corp. v. Illinois, 990 F.2d 288, 291 (7th Cir. 1993) (“The [E]leventh [A]mendment bar extends to suits for money damages against state officials sued in their official capacities … .”). Here, Driftless seeks (1) a declaration that Valcq and Huebsch had a due-process duty to recuse themselves from the permit proceeding; (2) a declaration that the permit is void as a matter of law; (3) an order vacating the permit; and (4) an injunction barring the enforcement of the permit. Declaratory and injunctive relief are paradigmatic examples of prospective relief. See Alden v. Maine, 527 U.S. 706, 747 (1999) (recognizing that Ex parte Young allows “certain suits for declaratory or injunctive relief against state officers” to proceed in federal court). But vacatur of the permit is retro- spective. Although an injunction and vacatur have similar real-world effects in that each will prevent construction of the power line, the two forms of relief have different legal consequences. A federal injunction does not erase an unconstitutional state law from existence; federal courts cannot repeal state laws. See Borden v. United States, 141 S. Ct. 1817, 1835 (2021) (Thomas, J., concurring) (“Courts have no authority to ‘strike down’ statutory text.” (cleaned up)); Skilling v. United States, No. 20-3325 17 561 U.S. 358, 424 (2010) (Scalia, J., concurring in part) (“I continue to doubt whether ‘striking down’ a statute is ever an appropriate exercise of our Article III power.”). Rather, a federal injunction prevents state officials from enforcing the challenged statute, regulation, or agency action in the future based on its incompatibility with federal law. An injunction operates on the enjoined officials; the law, regulation, or agency action remains on the books, and if the injunction is lifted by the issuing court, overturned by a higher court, or superseded by federal law, it resumes effect. See generally Jonathan F. Mitchell, The Writ-of-Erasure Fallacy, 104 VA. L. REV. 933 (2018). Vacatur, in contrast, retroactively undoes or expunges a past state action. Vacatur is “[t]he act of annulling or setting aside.” BLACK’S LAW DICTIONARY (11th ed. 2019). Unlike an injunction, which merely blocks enforcement, vacatur un- winds the challenged agency action. Ex parte Young does not encompass retroactive remedies like vacatur—and for good reason: the federal judiciary is not an oversight board over state agencies and has no power to vacate the actions of state agencies. That power belongs to the state courts, WIS. STAT. § 227.57(5), or the agency itself. Still, the complaint’s request for injunctive relief brings this case within Ex parte Young—provided, however, that Driftless has plausibly alleged an ongoing violation of federal law. 2. Ongoing Violation The more challenging aspect of Ex parte Young analysis is the proviso that the suit must seek relief against an “ongo- ing” violation of federal law. An ongoing violation of federal 18 No. 20-3325 law is one that is “continuing.” Green, 474 U.S. at 68. Because Ex parte Young is limited to federal-court orders “granting prospective injunctive relief to prevent a continuing viola- tion of federal law,” the doctrine does not apply when “federal law has been violated [only] at one time or over a period of time in the past.” Papasan v. Allain, 478 U.S. 265, 277–78 (1986). This part of the inquiry may seem simple at first, but “the difference between the type of relief barred by the Eleventh Amendment and that permitted under Ex parte Young will not in many instances be that between day and night.” Edelman, 415 U.S. at 667. This case lies in that twilight zone. It presents a difficult question of first impression: Is there an ongoing violation of federal law when the alleged violation is a procedural error committed by a state actor at a discrete point in time? The commissioners argue that the due-process violation (if there was one) was complete when the permit was approved and thus cannot be considered “ongoing” for purposes of Ex parte Young. Driftless insists that the violation is ongoing so long as the permit remains in force and effect and the Commission continues to exercise jurisdiction over the transmission companies in the present by virtue of its power to enforce, amend, or rescind the permit. Three cases are instructive here, although none is precise- ly on point. The first is Verizon v. Public Service Commission of Maryland. There, the telecommunications carrier Verizon negotiated an interconnection agreement with its competitor WorldCom as required by federal law. The state agency with jurisdiction over the matter approved the agreement, but a few months later, WorldCom filed a complaint with the agency accusing Verizon of violating the agreement. The No. 20-3325 19 agency ruled in favor of WorldCom on grounds pertaining to state contract law. Verizon then filed a federal lawsuit against the agency’s commissioners in their official capaci- ties alleging that the agency’s order was preempted by the Telecommunications Act of 1996 and a recent FCC ruling. Verizon, 535 U.S. at 639–40. The Supreme Court held that the Eleventh Amendment did not bar Verizon’s suit. Id. at 635. Verizon’s prayer for injunctive relief asked the federal court to enjoin the state officials “from enforcing the order in contravention of controlling federal law.” Id. at 645. That was sufficient to bring the case within Ex parte Young. Id. The second relevant precedent is MCI Telecommunications Corp. v. Illinois Bell Telephone Co., 222 F.3d 323 (7th Cir. 2000), another telecommunications case, though one from this court. There, the Illinois and Wisconsin utility commissions arbitrated several interconnection agreements between telecommunications companies. One of them sued the commissioners in their official capacities claiming that the approved agreements violated the Telecommunications Act. The commissioners raised sovereign immunity, arguing that “if any violations occurred, they occurred in the past,” so Ex parte Young did not apply. Id. at 345. We disagreed, observ- ing that the “challenged determinations are still in place, and the [plaintiffs] seek to have the commissioners conform their future actions, including their continuing enforcement of the challenged determinations, with federal law.” Id. The final case is Town of Barnstable v. O’Connor, 786 F.3d 130 (1st Cir. 2015), which involved a challenge to a state agency’s energy policy. A Massachusetts utility commission approved a merger between two electricity companies. The Town of Barnstable, joined by an environmental group and 20 No. 20-3325 several other plaintiffs, filed a federal suit alleging that the merger was incompatible with the Federal Power Act and also violated the dormant Commerce Clause. Citing Verizon, the First Circuit rejected the commissioners’ claim of sover- eign immunity. The court held in relevant part that “the continued enforceability of the [merger agreement] repre- sents an ongoing violation of federal law because [it] binds the parties to abide by the [agreement’s] allegedly unconsti- tutional terms.” Id. at 139. At first glance these cases seem closely analogous to this one. But there is a distinction. Each of these cases raised a substantive violation of federal law: the challenged state- agency determinations authorized the regulated parties to conduct their ongoing activities in violation of an FCC order, the Telecommunication Act, and the Federal Power Act and Commerce Clause, respectively. In contrast, this case raises a discrete procedural violation: the alleged due-process error occurred when commissioners with disqualifying conflicts of interest approved the power-line permit. In other words, Driftless does not assert that the permit substantively violates federal law (at least not in this suit); it challenges only the process by which the permit was issued. In the end, we’re not convinced that the difference be- tween substance and procedure is decisive. As the First Circuit observed in Town of Barnstable, the “continued en- forceability” of an unlawful state-agency decision can amount to an ongoing violation of federal law. Nothing in Ex parte Young or its successors suggests that the distinction between substantive and procedural violations makes a difference, so we hesitate to draw that line here. The relevant inquiry is whether the suit seeks prospective relief against an No. 20-3325 21 ongoing violation of federal law. A permit issued in viola- tion of due process remains unlawful as long as it is in force and effect. The commissioners point to Sonnleitner v. York, 304 F.3d 704 (7th Cir. 2002), which has surface similarity to this case— it too involved a due-process claim—but on close review is distinguishable. Sonnleitner involved a suit by a state em- ployee who was demoted without a predisciplinary hearing. He later prevailed at a postdeprivation hearing but was not reinstated, in part due to his own procedural missteps. He then sued his supervisors in federal court seeking an injunc- tion reinstating him to his position. He alleged that the denial of a predisciplinary hearing violated his right to due process. We held that the claim was barred by sovereign immunity. Id. at 718. Because the plaintiff was “eventually given an opportunity to tell his side of the story” at the postdeprivation hearing, we concluded that his due-process claim concerned “at most, a past rather than an ongoing violation of federal law.” Id. Our holding in Sonnleitner turned on the fact that the plaintiff had received a postdeprivation hearing that com- plied with due-process requirements. After the postdepriva- tion hearing, the alleged error in the predeprivation process could not be characterized as “ongoing.” The due-process violation at issue here is different. Driftless contends that the Commission’s approval of the permit was tainted by adjudi- cator bias in violation of the Due Process Clause. Finally, the commissioners argue that if this case is al- lowed to proceed under Ex parte Young, then all manner of final state-agency rulings will suddenly become reviewable in federal court based on allegations of adjudicator bias. This 22 No. 20-3325 would complicate state judicial review of agency rulings and erode state sovereign immunity. It could also open the floodgates to federal suits by parties complaining about biased state administrative adjudicators. We are sensitive to these concerns. Federal courts are not oversight boards designed to police the final actions of state agencies. Cf. River Park, Inc. v. City of Highland Park, 23 F.3d 164, 165 (7th Cir. 1994) (“Federal courts are not boards of zoning appeals.”). Challenges to state administrative actions usually belong in state courts, which are interested in and fully capable of ensuring that state agencies comply with federal due-process requirements. See Coeur d’Alene, 521 U.S. at 276 (“Where, as here, the parties invoke federal principles to challenge state administrative action, the courts of the State have a strong interest in integrating those sources of law within their own system for the proper judicial control of state officials.”). At bottom, these concerns rest on federalism principles. State sovereign immunity is, of course, rooted in the anchor- ing structure of our system of federalism. So too, however, is abstention doctrine. The commissioners’ arguments about federalism and comity are valid, but we think they are better addressed by abstention doctrine. For the foregoing reasons, we conclude that the due-process claim against them satis- fies the requirements of Ex parte Young and now move to the abstention question. B. Abstention The commissioners also asked the district judge to ab- stain and stay this case to await the outcome of the state litigation, citing both Younger and Colorado River abstention. No. 20-3325 23 The judge denied the request. We see no flaw in the judge’s analysis of Younger, but his Colorado River ruling rests on a misunderstanding of the claims in the state litigation, which in turn led him to mistakenly conclude that the federal and state cases are not parallel within the meaning of the doc- trine. 1. Raising Abstention Sua Sponte The abstention issue is not formally before us, but the Supreme Court has held that a reviewing court may raise abstention sua sponte in an appropriate case. See Bellotti v. Baird, 428 U.S. 132, 143 n.10 (1976) (“[T]he fact that the full arguments in favor of abstention may not have been asserted in the District Court does not bar this Court’s consideration of the issue.”). We have done so at least twice before, though the cases are a bit dated. We raised abstention sua sponte in Waldron v. McAtee, 723 F.2d 1348 (7th Cir. 1983), citing Bellotti and noting that a reviewing court has “the power and in an appropriate case the duty to order abstention, if necessary for the first time at the appellate level, even though no party is asking for it.” Id. at 1351. We explained that abstention doctrines do not exist “to protect the rights of one of the parties” but instead to “promote a harmonious federal system.” Id. We later charac- terized Waldron as recognizing a clear rule that “appellate courts are free to raise and resolve the abstention issue sua sponte.” Gen. Ry. Signal Co. v. Corcoran, 921 F.2d 700, 708 (7th Cir. 1991) (citing Waldron, 723 F.2d at 1351). We also raised abstention sua sponte in In re Complaint of McCarthy Brothers Co., 83 F.3d 821 (7th Cir. 1996), a compli- cated admiralty action involving an ironworker who was 24 No. 20-3325 injured while working on a barge on the Mississippi River. Admiralty law has its own arcane abstention doctrine known as Langnes abstention, which advises federal courts to “permit[] proceedings in state court to go forward on the question of liability and retain[] jurisdiction over any ques- tion that might arise as to the shipowner’s right to limit his liability.” Id. at 828 (describing Langnes v. Green, 282 U.S. 531 (1931)). Though no one argued the point, we decided “to raise the issue of abstention sua sponte,” explaining that reversal for application of Langnes abstention was necessary to correct the district court’s error and facilitate the “opera- tion of the complicated admiralty jurisdictional rules.” Id. at 826. This too is an appropriate case in which to raise absten- tion sua sponte. The error in the judge’s Colorado River ruling is plain, and our concerns about federal interference in ongoing state litigation justify taking this step. In so doing we follow the lead of our colleagues in the First Circuit. See Jiménez v. Rodríguez-Pagán, 597 F.3d 18, 27 n.4 (1st Cir. 2010) (“As with other forms of abstention, our decision to decline jurisdiction under Colorado River may be sua sponte.”). 2. Colorado River Abstention We begin with first principles. Although abstention “is the exception, not the rule,” Colorado River, 424 U.S. at 813, “a federal court may, and often must, decline to exercise its jurisdiction where doing so would intrude upon the inde- pendence of the state courts and their ability to resolve the cases before them,” SKS & Assocs., Inc. v. Dart, 619 F.3d 674, 677 (7th Cir. 2010). The main categories of abstention are known by the names of the Supreme Court cases that creat- No. 20-3325 25 ed them: Pullman, Burford, Younger, and Colorado River. 3 These categories are not rigid, however. The animating force of the Court’s abstention cases is that “they all implicate (in one way or another and to different degrees) underlying principles of equity, comity, and federalism foundational to our federal constitutional structure.” J.B. v. Woodard, 997 F.3d 714, 722 (7th Cir. 2021). Under the doctrine announced in Colorado River, a federal court may abstain and stay or dismiss a suit in deference to parallel state proceedings in exceptional circumstances where abstention would promote “wise judicial administra- tion.” 424 U.S. at 818. Several prudential principles are embedded in this highly generalized statement of the doc- trine. Among them are the interest in conserving judicial resources, the desirability of avoiding duplicative litigation and the risk of conflicting rulings, and the benefits of pro- moting a comprehensive disposition of the parties’ dispute in a single judicial forum. Id. We have found it useful to approach Colorado River ab- stention in two steps. DePuy Synthes Sales, Inc. v. OrthoLA, Inc., 953 F.3d 469, 477 (7th Cir. 2020). “The first question is whether the concurrent state and federal actions are actually parallel. If so, the second question is whether the necessary exceptional circumstances exist to support” abstention. Id. (cleaned up). “Two suits are considered parallel when substantially the same parties are contemporaneously litigating substantially 3R.R. Comm’n of Tex. v. Pullman Co., 312 U.S. 496 (1941); Burford v. Sun Oil Co., 319 U.S. 315 (1943); Younger v. Harris, 401 U.S. 37 (1971); Colo. River Water Conservation Dist. v. United States, 424 U.S. 800 (1976). 26 No. 20-3325 the same issues in another forum. Formal symmetry is unnecessary, as long as there is a substantial likelihood that the state litigation will dispose of all claims presented in the federal case.” Id. at 477–78 (cleaned up). On this understand- ing, there is no doubt that the state and federal suits here are parallel. True, the suits are not completely identical: the state litiga- tion raises state-law issues in addition to the duplicative due-process claim. But perfect symmetry isn’t necessary. The cases are parallel in all the ways that matter under Colorado River. The due-process recusal claims “involve the same parties, the same facts, and the same issues.” Id. at 478. Indeed, the claims are materially identical: they will “be resolved by examining largely the same evidence,” Huon v. Johnson & Bell, Ltd., 657 F.3d 641, 647 (7th Cir. 2011), and are governed by the legal standard announced in Caperton. So it’s not just “substantially likely” that the state litigation will dispose of the federal case—it is nearly certain that it will do so. The second step in the framework is to determine wheth- er exceptional circumstances justify abstention. A plethora of nonexclusive, unweighted factors can inform this question, including: 1. Whether the case concerns rights in prop- erty, and if so, whether the state has as- sumed jurisdiction over that property; 2. The inconvenience of the federal forum; 3. The desirability of consolidating litigation in one place (put otherwise, the value in avoiding “piecemeal” or broken-up pro- ceedings); No. 20-3325 27 4. The order in which jurisdiction was ob- tained in the concurrent fora; 5. The source of governing law—federal or state; 6. The adequacy of the state-court action to protect the federal plaintiff’s rights; 7. The relative progress of the state and fed- eral proceedings; 8. The presence or absence of concurrent ju- risdiction; 9. The availability of removal; and 10. Whether the federal action is vexatious or contrived. DePuy, 953 F.3d at 477. We have cautioned that this overa- bundant list of factors “is designed to be helpful, not a straitjacket. Different considerations may be more pertinent to some cases, and one or more of these factors will be irrelevant in other cases.” Loughran v. Wells Fargo Bank, N.A., 2 F.4th 640, 647 (7th Cir. 2021). Nor does the list “preclude the district court from taking into account a special charac- teristic of the case before it.” DePuy, 953 F.3d at 477. More generally, the decision to abstain “does not rest on a mechanical checklist, but on a careful balancing of the important factors.” Moses H. Cone Mem’l Hosp. v. Mercury Constr. Corp., 460 U.S. 1, 16 (1983). In short, abstention law doesn’t demand an exact fit with the precise parameters of a doctrinal category. J.B., 997 F.3d at 723–24. Instead, the abstention inquiry is flexible and requires a practical judg- ment informed by principles of comity, federalism, and sound judicial administration. 28 No. 20-3325 With these principles in mind, we find it neither neces- sary nor helpful to march through our 10-factor “test” and decide which factors support abstention and which do not. DePuy, 953 F.3d at 479 (explaining that the factors in a multi- factor, unweighted test often point in different directions); see also United States v. Mayfield, 771 F.3d 417, 435 (7th Cir. 2014) (en banc) (“Multifactor tests are common in our law but they can be cryptic when unattached to a substantive legal standard, as this one is. Knowing what factors to look at is useless unless one knows what to look for.”). Several compelling considerations justify abstention in this case, and all can be loosely keyed to the factors on the list. The first is the desirability of avoiding piecemeal litiga- tion over the legality of the power-line permit. Multi- jurisdictional legal challenges involving the same subject matter are costly, disruptive, and run the risk of a collision of conflicting rulings. A related consideration is the wholly duplicative nature of this suit. The takings claim was doomed from the start and can fairly be characterized as contrived, and there is no good reason to litigate identical due-process recusal claims in state and federal court. See Interstate Material Corp. v. City of Chicago, 847 F.2d 1285, 1289 (7th Cir. 1988) (holding that a federal lawsuit “could be considered” contrived when the plaintiff files parallel suits “seeking substantially the same relief from substantially the same parties”). Needless to say, the state courts routinely apply federal constitutional standards, as they must under the Supremacy Clause. More to the point here, Wisconsin courts are fully capable of applying Caperton and have begun to do so. See In re Paternity of B.J.M., 944 N.W.2d 542, 549 (Wis. 2020). And No. 20-3325 29 they have long applied federal due-process standards to recusal questions involving administrative adjudicators. See Guthrie v. Wis. Emp. Rels. Comm’n, 331 N.W.2d 331, 336 (Wis. 1983). So there is nothing about this particular legal context that cautions against abstention. To the contrary, it appears that Driftless simply wants two bites at the apple. And that weighs heavily in favor of abstention. What’s more, the state case has advanced toward a reso- lution of the due-process claim. As we’ve explained, the Dane County judge already ruled against Driftless on its allegations against Valcq. The allegations involving Huebsch remain, but the case is now before the Wisconsin Supreme Court on that issue. The petition for review raises substan- tive questions about the application of Caperton—both in general and in light of the specific allegations involving Huebsch. Under these circumstances, the use of federal judicial resources to decide the same questions cannot be justified. “The principal purpose of a stay under Colorado River is judicial economy … .” Schneider Nat’l Carriers, Inc. v. Carr, 903 F.2d 1154, 1157 (7th Cir. 1990). There is “no reason for identical suits to be proceeding in different courts.” U.S.O. Corp. v. Mizuho Holding Co., 547 F.3d 749, 750 (7th Cir. 2008). Judicial economy strongly favors abstention. That brings us to a final consideration, and it is far from the least important one. Although Colorado River abstention is primarily concerned with judicial economy, it also imple- ments the fundamental federalism principles that animate all abstention categories. See, e.g., Adkins v. VIM Recycling, Inc., 644 F.3d 483, 486 (7th Cir. 2011) (describing Colorado River as a “federalism doctrine”); Black Sea Inv., Ltd. v. United Heritage Corp., 204 F.3d 647, 650 (5th Cir. 2000) (“The Colorado River 30 No. 20-3325 abstention doctrine is based on principles of federalism, comity, and conservation of judicial resources.”). Federalism concerns loom large here. This case impli- cates Wisconsin’s sovereign interest in the proper function- ing of its administrative law and procedure and the role of the state courts in reviewing the decisions of administrative agencies. Wisconsin has created an elaborate permitting regime for important public-utility projects like this one, and aggrieved persons are entitled to judicial review in the state courts. See generally WIS. STAT. § 227.53. Only the state courts can review the agency’s work for compliance with the procedural and substantive requirements of state law. And the state courts alone have the authority to vacate the permit and order the Commission to conduct a new hearing— whether as a remedy for a violation of state law or as a remedy for a violation of the federal constitutional guarantee of due process. Conversely, there is no significant federal interest at stake here that necessitates or even encourages federal-court review of the procedural regularity of the permit proceeding before the agency. A foundational premise of our federalism is “the assumption that state courts are co-equal to the federal courts and are fully capable of respecting and pro- tecting” federal constitutional rights. Courthouse News Serv. v. Brown, 908 F.3d 1063, 1074 (7th Cir. 2018). “Principles of comity entitle the states to make their own decisions, on federal issues as well as state issues, unless there is some urgent need for federal intervention.” Nicole K. ex rel. Linda R. v. Stigdon, 990 F.3d 534, 537–38 (7th Cir. 2021). The federal courts have no institutional superiority in ruling on Caperton No. 20-3325 31 claims. 4 Accordingly, “[e]xercising federal jurisdiction over [this] claim[] would reflect a lack of respect for the state’s ability to resolve the[] issues properly before its courts.” J.B., 997 F.3d at 722 (quotation marks omitted). Finally, the recent developments before the agency are worth mentioning. As we’ve noted, the Commission recently reopened its proceedings to determine whether to rescind and reconsider the permit based on the conflict-of-interest allegations involving Huebsch. Of course, we cannot predict what it will do. But if the Wisconsin Supreme Court rules in favor of Driftless and allows the due-process claim to move forward in Dane County Circuit Court, remedial steps by the Commission would not be surprising. In short, abstention under Colorado River is amply justi- fied. The judge was wrong to conclude otherwise. III. Conclusion For the foregoing reasons, the judge correctly denied the commissioners’ motion to dismiss based on sovereign immunity. But he incorrectly denied the motion for Colorado 4 By our count, we have addressed Caperton claims in just five reported cases: Gacho v. Wills, 986 F.3d 1067, 1071–76 (7th Cir. 2021); United States v. Williams, 949 F.3d 1056, 1061–63 (7th Cir. 2020); Wozniak v. Adesida, 932 F.3d 1008, 1011 (7th Cir. 2019); Alston v. Smith, 840 F.3d 363, 368–69 (7th Cir. 2016); and Suh v. Pierce, 630 F.3d 685, 691–92 (7th Cir. 2011). Another four make passing reference to Caperton: Trustmark Ins. Co. v. John Hancock Life Ins. Co., 631 F.3d 869, 872 (7th Cir. 2011); Bauer v. Shepard, 620 F.3d 704, 712 (7th Cir. 2010); Siefert v. Alexander, 608 F.3d 974, 980 (7th Cir. 2010); and Chen v. Holder, 607 F.3d 511, 513 (7th Cir. 2010). Not that case counts matter. The Wisconsin Supreme Court is equally capable of applying Caperton, even if it has done so less frequently than this court. 32 No. 20-3325 River abstention. We therefore REVERSE and REMAND with instructions to stay this case pending dispositive develop- ments in the state litigation. The motion to partially lift the stay pending appeal is denied as moot.
