This appeal involves the efforts of two natural gas pipelines, in the face of burgeoning economic competition in the deregulated energy industry, to deal with what they regard as the unequal property tax system in Kansas vis:a-vis the pipelines’ traditional competitors, railroad companies, as well as the pipelines’ claims of unfair judicial process in the state courts of Kansas. We must dismiss this appeal, vacate the district court’s judgment, and direct the district court to dismiss all claims in this case against both the state agency defendants and the state official defendants. The Eleventh Amendment stands as a bar to federal jurisdiction over all of these claims, and the plaintiffs’ suit is not saved by the Ex parte Young doctrine.
Background
These two appeals arise out of a single district court order denying a motion to dismiss under Fed.R.Civ.P. 12(b)(1) for lack of subject-matter jurisdiction, filed by the state agency defendants and the state official defendants (collectively referred to as “state defendants”) two weeks after the plaintiffs filed this suit. 1 The state defendants filed one appeal, No. 96-3250, as an “appeal by right” based on the district court’s denial of the state defendants’ claim of sovereign immunity under the Eleventh Amendment. Subsequently, the state defendants also filed a separate motion seeking permission to file a second interlocutory appeal challenging that portion of the court’s decision involving the Tax Injunction Act and the Rooker /Feldman doctrine. The motion was granted, and this second appeal was denominated No. 96-3345. Despite this procedural división of the issues between the two separate appeals, we believe the interests of justice would be best *1183 served by consolidating both appeals and disposing of this case in a single opinion. 2
1. The Jp-R Act.
The seeds of this property tax dispute were planted in the Railroad Revitalization and Regulatory Reform Act of 1976 (“4-R Act”), Pub.L. 94-210, 90 Stat. 81 (codified as amended at 49 U.S.C. § 11501 (1994)). Under this legislation, Congress prohibited state and local taxing agencies from imposing discriminatory taxes on railroads.
See
49 U.S.C. § 11501(b). The legislation generated vast amounts of litigation in which railroads alleged that various taxing schemes by states and local governments violated the 4-R Act.
See, e.g., Burlington N. R.R. Co. v. Huddleston,
Seeing this dramatic tax break for their competitors, several natural gas pipeline companies requested similar treatment from the Kansas Division of Property Valuation, but the state refused. The pipeline companies then went to court. From the outset of the litigation underlying these appeals, the pipeline companies have argued that they are similarly situated vis-a-vis the railroad companies, i.e., that both are public utilities under Kansas law. See Kan. Stat. Ann. §§ 79-5a01(a)(1) & (a)(4) (1989). The pipelines argue that they have an equal protection right to the same tax breaks provided to the railroads. See U.S. Const., XIV amend., § 1.
Key to the pipelines’ equal protection claim is their concomitant allegation that they were denied procedural due process by the tax appeal proceedings in Kansas at both the administrative and judicial level. For this reason, the sequence of events, in the underlying litigation is important.
2. The pipelines’ state-court litigation.
After the August 11, 1989, consent decree exempting much of the railroads’ Kansas personal property from taxation, the pipelines filed suit in Shawnee County District Court claiming their 1989 tax assessment by the Kansas Division of Property Valuation violated state and federal guarantees of equal protection. In an unreported decision, the state district court dismissed the suit for lack of subject-matter jurisdiction because the pipelines had failed to file an appeal of the assessment before the Kansas Board of Tax Appeals (“BOTA”). In 1993, the Kansas Court of Appeals reversed the district court’s decision and remanded the case for consideration of the pipelines’ equal protection arguments.
See Colorado Interstate Gas Co. v. Beshears,
During the pendency of this first ease, the pipelines filed appeals of their 1990 and 1991 tax assessments with BOTA, again claiming that the lack of favorable exemptions for themselves, vis-a-vis the railroads, violated the pipelines’ rights to equal protection. The 1990 and 1991 appeals were submitted to BOTA on a stipulated record, and the Board rejected the challenges. The pipelines appealed that decision to the Kansas Supreme Court, which affirmed the BOTA decision.
See In re Appeal of ANR Pipeline Co.,
*1184
Just three days after the Kansas Supreme Court filed its decision in
CIG II (ANR Pipeline),
the Supreme Court of the United States filed a decision in an unrelated case dealing with a similar issue of state property tax exemptions for railroads under the 4-R Act.
See Department of Revenue v. ACF Indus., Inc.,
In Kansas, the pipelines interpreted the Supreme Court’s decision in
ACF Industries
as a frontal assault on the rationale of the earlier Kansas Supreme Court decision in
CIG II (ANR Pipeline).
Consequently, the pipelines filed a motion for rehearing in
CIG II (ANR Pipeline),
arguing that the Supreme Court’s decision in
ACF Industries
seriously undermined the Kansas court’s justification under the 4-R Act. The Kansas Supreme Court summarily denied the petition for rehearing without comment. The pipelines then filed a petition for a writ of certiorari, arguing in part that the Kansas decision in
CIG II (ANR Pipeline)
was inconsistent with the Supreme Court’s decision in
ACF Industries.
The Supreme Court denied the certiorari petition without comment.
See ANR Pipeline Co. v. Director of Property Valuation,
During the pendency of this CIG II (ANR Pipeline) litigation, the pipelines filed new appeals of their 1992 and 1993 tax assessments with BOTA. This time, in addition to their equal protection claims, the pipelines argued that the Kansas Supreme Court’s decision in CIG II (ANR Pipeline) had been effectively overruled by the U.S. Supreme Court’s decision in ACF Industries. The 1992 appeal was submitted on the basis of stipulated facts, but there was no stipulation with respect to the 1993 appeal. BOTA dismissed both appeals without taking any evidence on the question of the disparate treatment between the railroads and the pipelines. BOTA ruled that its decision must be controlled by the Kansas Supreme Court’s ruling in CIG II (ANR Pipeline). 3
The pipelines appealed again to the Kansas Supreme Court, this time on the basis of their 1992 and 1993 tax appeals, asking the court to instruct BOTA that
CIG II (ANR Pipeline)
was no longer controlling law. Instead, the Kansas Supreme Court ruled on the pipelines’ constitutional claims.
See In re Appeals of Colorado Interstate Gas Co.,
While the granting of the 80% personal property tax exemption may have been based upon the belief that the 4-R Act required it, a belief that may be false in light of the United States Supreme Court’s decision in ACF Industries, the settlement represents a. cost-benefit analysis of continued litigation....
We are not prepared to state that the granting of the 80% personal property tax exemption to the named railroads in protracted federal litigation, as part of a nego *1185 tiated settlement discriminated against CIG and ANR.
Id.
3. The pipelines’federal court litigation.
Rather than file a petition for a writ of certiorari on this latest Kansas Supreme Court decision, the pipelines filed the instant action in federal district eourt. The complaint asserted federal eourt jurisdiction under 28 U.S.C. § 1331 (federal-question jurisdiction) and 28 U.S.C. § 1343 (civil-rights jurisdiction) and alleged that the Tax Injunction Act, 28 U.S.C. § 1341, was no bar to the federal court’s jurisdiction. 4 The pipelines’ complaint involved the state’s property tax valuations of their personal property from 1990 to 1993, alleging that those valuations violated the pipelines’ federal equal protection and due process rights under the Fourteenth Amendment. 5 The pipelines’ complaint requested money damages against the county defendants and declaratory and equitable relief against the state defendants. The declaratory relief sought was a declaration that “Defendants have and continue to wrongfully value, assess, tax, and retain excessive taxes paid by [the pipelines] that are substantially different from those valued, assessed, taxed, collected and retained from similarly situated taxpayers, without a rationally based legitimate state interest, in violation of the Equal Protection Clause of the United States.” This declaratory judgment request also asked the district eourt to take the -following action: “to declare that [the Division of Property Valuation] should recertify to Counties for subject and future tax years lawful values which comply with state and federal constitutions.” 6
In response to this complaint, the county defendants filed cross-claim complaints against the state defendants, which the state defendants answered, and all the defendants filed various motions under Fed.R.Civ.P. 12(b)(1) asking the district court to dismiss the plaintiffs suit. The district court dismissed the county defendants’ motions to dismiss in the same order on appeal here, but because the county defendants are not parties to this appeal, we decline to consider the district court’s decision on those motions.
Finally, as the defendants’ motions were pending in federal district court, the last installment of the Kansas state-court proceedings went forward in the Shawnee County District Court, where the state eourt took up the remand it had received with respect to the 1989 tax assessment in
CIG I.
The state filed a motion for summary judgment, arguing that the constitutional claims raised by the pipelines had been decided by the Kansas Supreme Court in
CIG III.
The pipelines, on the other hand, filed a motion for a stay pending the outcome in federal district court on their federal-court claims, including their claim that the Kansas courts had failed to provide due process on the pipelines’ equal protection claims. Without conducting a hearing' on either motion, the state district court apparently issued an order dismissing
*1186
the motion for a stay and granting summary judgment to the state on the basis of the Kansas Supreme Court decision in
CIG III.
In a second appeal to the Kansas Court of Appeals, the appellate court again reversed the district court, although we have no indication in the record before us of the basis of that unpublished decision or its instructions to the lower court.
See Colorado Interstate Gas Co. v. Beshears,
k. The federal district court’s ruling.
In the face of this complex procedural history, the federal district court below issued the Memorandum and Order that is on appeal here:
ANR Pipeline Co. v. Lafaver,
No. 96-1089-JTM,
The district court also ruled that the pipelines’ claims in this case did not violate the
Rooker /Feldman
doctrine barring lower federal court review of state court decisions because the pipelines had narrowly focused their suit away from any federal court review of the Kansas Supreme Court’s decisions in
CIG II (ANR Pipeline)
and
CIG III. See CIG IV,
Finally, on the state defendants’ claim of Eleventh Amendment immunity, the- district court ruled that to the extent the pipelines sought money damages, their suit was actually against the county defendants, which are not arms of the state, and thus was not blocked by the Eleventh Amendment. See id. at *3. The district court held that the remaining claims against the state defendants came within the Ex parte Young rule under the Eleventh Amendment because these claims sought only prospective relief for a violation of “the constitutional guarantees of Kansas and the United States.” Id. at *2.
Following the denial of their motion for reconsideration, the state defendants took the instant appeals. Despite the interlocutory nature of this case, we have appellate jurisdiction over the district court’s ruling on the Eleventh Amendment issue under the collateral order doctrine of
Puerto Rico Aqueduct & Sewer, Auth. v. Metcalf & Eddy, Inc.,
I. State sovereign immunity. 8
Two landmark Supreme Court cases on the scope of a state’s sovereign
*1187
immunity under the Eleventh Amendment ultimately control the outcome of this case.
See Idaho v. Coeur d’Alene Tribe,
A. The Eleventh Amendment.
The text of the Eleventh Amendment was proposed and quickly adopted by the states soon after the Supreme Court handed down its decision in
Chisholm v. Georgia,
The Judicial power 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, or by Citizens or Subjects of any Foreign State.
U.S. Const., XI amend. Although the language of the text does not require it, the Supreme Court consistently has interpreted the Eleventh Amendment as barring not only suits against a state by citizens of another state, but also suits against a state by that state’s own citizens.
See Hans v. Louisiana,
Applying this notion of sovereign immunity, the .Court has held that a citizen’s suit against a state agency is barred by the Eleventh Amendment just as surely as if the suit had named the state itself.
See Pennhurst State Sch. & Hosp. v. Halderman,
There are two narrow exceptions to the doctrine of sovereign immunity as it is
*1188
enshrined in the Eleventh Amendment: 1) A state may waive its Eleventh Amendment immunity by consenting to be sued, but only in the clearest and most unmistakable terms, and 2) Congress may abrogate the states’ Eleventh Amendment immunity, but again, only by using the clearest and most unmistakable terms, and only when Congress is exercising a power granted to it by a constitutional amendment post-dating the . Eleventh Amendment, i.e., principally section 5 of the Fourteenth Amendment.
See Aaron v. Kansas,
B. The Ex parte Young “exception.”
1. The traditional view.
A third route for a party to obtain relief against a state agency in federal court is the so-called
Ex parte Young
“exception” to the Eleventh Amendment, although in nominal form the rule is not an “exception” because the citizen’s suit is not against the state, but rather it is a suit against a state official. In such a suit, when a party seeks only prospective equitable relief — as opposed to any form of money damages or other legal relief — then the Eleventh Amendment generally does not stand as a bar to the exercise of the judicial power of the United States.
See Ex parte Young,
Under the
Ex parte Young
legal fiction, when an official of a state agency is sued in his official capacity for prospective equitable relief, he is generally not regarded as “the state” for purposes of the Eleventh Amendment and the case may proceed in federal court.
10
See Green v. Mansour,
[W]hen a suit names a state official as the defendant, the Eleventh Amendment still bars the action if “the state is the real, substantial party in interest.” Whether the state is the real party in interest turns on the relief sought by the plaintiffs. Suits that seek prospective relief are deemed to be suits against the official, while suits that seek retroactive relief are deemed to be suits against the state.
Powder River Basin,
Of course, because of the important interests of federalism and state sovereignty implicated by the
Ex parte Young
doctrine, the rule has its limits. First, federal courts havq no jurisdiction to entertain a suit that seeks to require the state official to comply with state law — only allegations of violations of federal law are sufficient to come within the
Ex parte Young
rule.
See Pennhurst,
These limitations on the
Ex parte Young
doctrine are well-settled, and they informed the Supreme Court’s recent pronouncement that “We do not, then, question the continuing validity of the
Ex parte Young
doctrine.”
See Coeur d’Alene Tribe,
2. New case law.
The first shift arose in
Seminole Tribe,
a case that involved a federal suit by an Indian tribe seeking' to force the state of Florida to comply with provisions of the Indian Gaming Regulatory Act (“IGRA”).
Seminole Tribe,
We read in Seminole Tribe an obligation for the federal courts to examine Congress’ stated intent with respect to the scope of statutory remedies that may be available in any case where an Ex parte Young issue is raised. The crucial inquiry is whether Congress has expressed an intent, through some kind of statutory scheme, to limit or prevent potential remedies in a private cause of action even though broader remedies might otherwise be available against the state through the Ex parte Young rule. If so, then under Seminole Tribe, the federal courts are not ordinarily free to go beyond that congressional intent.
The second narrowing of the
Ex parte Young
doctrine arose in.
Coeur d’Alene Tribe,
a case involving a federal suit by an Indian tribe seeking a declaratory judgment establishing its right to quiet enjoyment over the
*1190
submerged lands of Lake Coeur d’Alene, in addition to seeking prospective injunctive relief against numerous Idaho state officials to prevent them from exercising the state’s asserted regulatory jurisdiction over those submerged lands.
Coeur d’Alene Tribe,
It is apparent, then, that if the Tribe were to prevail, Idaho’s sovereign interest in its lands and waters would be affected in a degree fully as intrusive as almost any conceivable retroactive levy upon funds in its Treasury.... The dignity and status of its statehood allows Idaho to rely on its Eleventh Amendment immunity and to insist upon responding to these claims in its own courts, which are open to hear and determine the case.
Id. at 2042 (Kennedy, J., majority opinion).
We read Coeur d’Alene Tribe as imposing an important new requirement on federal courts as part of the Ex parte Young analysis. In light of Coeur d’Alene Tribe, federal courts must examine whether the relief being sought against a state, official “implicates special sovereignty interests.” If so, we must then determine whether that requested relief is the “functional equivalent” to a form of legal relief against the state that would otherwise be barred by the Eleventh Amendment. In the end, wé must not extend the Ex parte Young doctrine to allow a suit for prospective equitable relief when that relief would be just as intrusive, if not more so, into core aspects of a state’s sovereignty.
C. Kansas’ state sovereignty over taxation issues.
With this understanding of the doctrine of sovereign immunity under the Eleventh Amendment, we now turn to the effect of that doctrine on the suit by the natural gas pipelines against the Kansas officials in charge of property tax valuations for the state of Kansas. In their suit, the pipelines have asked the court to declare that these state defendants “have and continue to wrongfully value, assess and retain excessive taxes” against the pipelines. They also have asked the court to declare that the director .of the Division of Property Valuation “should recertify to Counties for subject and future tax years lawful values which comply with state and federal constitutions.”
It is evident merely from reading the text of these requests for declaratory relief that at least a portion of the requested relief runs afoul of some of the long-accepted principles of the
Ex parte Young
doctrine.
*1191
As discussed above, federal courts may not invoke
Ex parte Young
in order to consider claims for retrospective relief or claims that seek an adjudication of the legality of past state conduct.
See Papasan,
On the basis of these two principles, we conclude that Ex parte Young cannot be invoked to preserve fedéral jurisdiction- for that portion of the pipelines’ equitable claims that seek retrospective relief. Thus, there is no federal jurisdiction to declare that the state defendants have wrongfully valued the pipelines’ property in the past. And, there is no federal jurisdiction to declare that the state defendants should recertify past tax year assessments. Both of those requests fall outside the scope of the Ex parte Young doctrine, and as a result, they fall squarely within the Eleventh Amendment’s bar of sovereign immunity.
The only remaining claims that might lie within the Ex parte Young doctrine are the pipelines’ requests for declarations as to 'the state defendants’ ongoing practices and the property valuations for future years. However, these claims run afoul of the doctrinal requirements of Seminole Tribe and Coeur d’Alene Tribe, and as a result, we conclude that these equitable claims also are barred by the Eleventh Amendment.
1. Prospective relief under Seminole Tribe.
According to Seminole Tribe, we must evaluate whether the equitable relief being sought through the Ex parte Young mechanism is broader than the relief Congress has otherwise circumscribed in relevant statutes. If so, the Ex parte Young mechanism for avoiding the Eleventh Amendment is not available.
Under the analysis required by Seminole Tribe, we find that the Tax Injunction Act, 28 U.S.C. § 1341 ’(1994),. is the appropriate statute on which to base a comparison between the judge-made Ex parte Young doctrine and Congress’ statutory scheme. 13 In the Tax Injunction Act Congress expressly limited the power of federal courts to issue certain types of remedies pertaining to the assessment, levy or collection of state taxes. Furthermore, we find that the criteria for relief under the Tax Injunction Act are significantly narrower than the criteria under Ex parte Young. As a result, we conclude that the Ex parte Young doctrine may not be invoked for the pipelines’ prospective claims that seek relief that is precluded by the Tax Injunction Act. .
The Tax Injunction Act. provides that federal courts “shall not enjoin, suspend or restrain the assessment, levy or collection of any tax under State law where a plain, speedy' and efficient remedy may bé had in the courts of such State.” 28 U.S.C. § 1341. Thus, the Act clearly functions as a limitation on the equitable remedies a federal court may provide in a property tax dispute that otherwise has appropriate federal court subject-matter jurisdiction, i.e., federal question jurisdiction or diversity jurisdiction. Under the Tax Injunction Act, the only avenue by which a claim for injunctive relief against state or local taxes may be brought to federal court is where the state has failed to provide a “plain, speedy and efficient remedy.”
See id.
The Act means that a state must provide a forum, according to the Supreme Court, that allows an “opportunity to raise constitutional objections” to the contested tax.
See California v. Grace Brethren Church,
457
*1192
U.S. 393, 412 & n. 26,
There is no such similar limit on the scope of the
Ex parte Young
doctrine. Indeed, it appears to be clear from the concurring and dissenting opinions in
Coeur d’Alene Tribe
that an
Ex parte Young
injunction still may issue even when the state courts would provide an adequate forum for the plaintiffs constitutional claims.
See Coeur d’Alene Tribe,
As a result, we cannot avoid the conclusion that when a state provides an adequate forum for a plaintiffs federal claims, the criteria for a remedy under
Ex parte Young
are broader than the criteria under the Tax Injunction Act.
14
On the basis of that conclusion, the rule in
Seminole
Tribe—that federal . courts may not imply the judge-made remedy of
Ex parte Young
when Congress has provided a more narrowly circumscribed remedy—controls this case.
15
See Seminole Tribe,
Seeking an escape from this doctrinal logic, the pipelines allege that the
Ex parte Young
mechanism is still available for this suit because Kansas consistently has failed to provide an adequate state remedy. The district court agreed with both the conclusion and the premise of this argument.
See CIG IV,
2. Prospective relief under Coeur d’Alene Tribe,
In
Coeur d’Alene Tribe,
a majority of the justices clearly held that the
Ex parte Young
mechanism for federal-court injunctive relief is not available when the relief “implicates special sovereignty interests.”
Coeur d’Alene Tribe,
521 U.S. at-,
In Coeur d’Alene Tribe, the Court sought to answér the question of whether state ownership and regulation of submerged lands within its borders “implicates special sovereignty interests” by reviewing the doctrines of sovereignty going as far back as Justinian’s Institutes. The Court catalogued the unique position of state sovereignty over navigable waters that then existed in the English common law and later was imported into the American legal system.
For our own purposes, we need not go so far as an inquiry into Roman law
16
because Congress has done our work for us. Congress has made it clear in no uncertain terms that a state has a special and fundamental interest in its tax collection system.
See
Act of Aug. 21, 1937 (Tax Injunction Act), Pub.L. No. 332, 50 Stat. 738, ch. 726, § 1, (1937) (codified at 28 U.S.C. § 1341);
see also
S. Rep. 1035, 75th Cong., at 2 (1937) (noting that the Tax Injunction Act was intended to protect states from well-financed litigants who' could “seriously disrupt State and county finances” by withholding tax payments during the course of federal-court litigation). As the Supreme Court explained in
Rosewell,
the Tax Injunction Act “was first and foremost a vehicle to limit drastically federal district court jurisdiction to interfere with so important a local concern as the collection of taxes.”
Rosewell,
*1194 Furthermore, we have no hesitation in concluding that the declaratory relief requested by the pipelines&emdash;i.e., that the state of Kansas should “recertify” its tax assessment of the pipelines’ personal property in Kansas&emdash;is “fully as intrusive” into the state’s sovereignty as would be a retroactive money judgment against excessive property taxes. 17 See id. at 2043. The pipelines’ request to rewrite Kansas’ property tax code with respect to its application against the personal property of natural gas pipelines is certainly a major intrusion into Kansas’ special sovereignty interests. The Eleventh Amendment stands as a barrier to such a request. The Eleventh Amendment requires that the pipelines’ claims against the state of Kansas must be brought in state court.
The pipelines argue that it would be the height of injustice to require them to bring their federal constitutional claims in the state courts of Kansas when, one of their claims is that Kansas has failed to provide the pipelines with minimal guarantees of procedural due process. Although we recognize the predicament the pipelines face,' we are constrained by the Eleventh Amendment and the special sovereignty interest a state has in the control of its property tax system. The Supreme Court has held that in cases implicating the core powers óf a state qua state, the Eleventh Amendment directs a litigant to the state’s courts. Of course, a litigant always may seek review of the state court decisions by the U.S. Supreme Court through a petition for certiorari. See 28 U.S.C. § 1257. As lower federal courts, however, this court and the federal district court in Kansas may not entertain the pipeline’s suit ultimately seeking federal declaratory relief against the tax policy of the state of Kansas. The relief sought by the pipelines impermissibly intrudes upon Kansas’ “dignity and status” as a sovereign government.
II. The state defendants’ additional claims.
In addition to its holding under the
Ex parte Young
doctrine, the district court rejected the state defendants’ other arguments against federal jurisdiction. The court held that the pipelines’ suit was not barred by either the Tax Injunction Act or the
Rooker /Feldman
doctrine.
See CIG IV,
Conclusion
In the interests of judicial economy, we hereby CONSOLIDATE these two appeals, and we GRANT the appellees’ motion to dismiss the named Kansas state agencies as defendants and to dismiss their state-law claims based on the Kansas Constitution and Kansas common law.
Furthermore, relying on the jurisdictional bar imposed by the Eleventh Amendment, *1195 we conclude that these appeals must be DISMISSED, the judgment of the district court VACATED, and the case REMANDED to the district court with instructions to dismiss all claims against the remaining state defendants in this ease.
Notes
. A second group of defendants, involving most of Kansas’ county commissioners and county treasurers [hereinafter the "county defendants”], were parties below but they have not filed their own interlocutory appeal in this case. As a result, this opinion is limited solely to the question of jurisdiction over the state defendants.
Following oral argument, the plaintiffs-appel-lees filed an uncontested motion with this court to dismiss the state agency defendants from this case. In light of our resolution of this appeal, it is apparent that the plaintiffs-appellees cannot maintain this federal action against the state agency defendants. Accordingly, we grant the plaintiffs-appellees' motion to dismiss the Kansas Department of Revenue and the Kansas Division of Property Valuation as defendants.
Based on this ruling, then, the only defendants still germane to this appeal are the two state official defendants: the secretary of the Department of Revenue and the director of the Division of Property Valuation.
. As a result, we direct the Clerk to consolidate these two appeals.
. From the text of the BOTA ruling, it appears that the Board did not address the constitutional claims raised by the pipelines. The Board said that in CIG II (ANR Pipeline), "[t]he Kansas Supreme Court ruled that the 4-R Act only applies to railroads.... The taxpayer is not a railroad and thus, is not entitled to the similar tax treatment provided by the 4-R Act." The Board apparently did not address the pipelines’ claim that whether or not the pipelines met the definition of a railroad, they were similarly situated with the railroads as public utilities, and as a consequence, they were entitled to equal treatment.
. The pipelines sought and received permission to amend their original complaint, but the additional claims in the amended complaint were not before the district court when it considered the state defendants’ motion to dismiss-, and as a consequence, those claims are not before us in this appeal.
. The pipelines also asserted state-law claims for violations of the Kansas Constitution’s equal protection and uniform taxation clauses, as well as a claim under Kansas common law for unjust enrichment. However, following oral arguments, the pipelines submitted a motion in this court to dismiss these state-law claims against the state defendants, which we grant.
. The pipelines’ request for a “declaration” that the state "should recertify” the pipelines’ tax assessment might be more accurately characterized as a request for an "injunction.” However, the pipelines adamantly insist that they have not asked for injunctive relief; they insist that their complaint against the state defendants seeks only declaratory, relief. (See Appellees Letter of Mar. 24, 1997 to Tenth Circuit Court of Appeals (responding to the appellant’s submission of supplemental authority).) Nevertheless, the characterization of this form of relief as "declaratory” or "injunctive” is not dispositive to our resolution ' here, and thus, we need not wade into that muddy water.
. In its Memorandum Order denying the motion for reconsideration, the district court granted the state defendants’ separate request for interlocutory certification of the appeal in No. 96-3345 under 28 U.S.C. § 1292(b).
. We note that federal courts should avoid reaching the merits of a constitutional issue when the *1187 case may be decided on statutory grounds. However, in this case, we turn first to the constitutional issue of state sovereign immunity because it presents a controlling jurisdictional question that is antecedent to the other two issues raised on appeal, i.e., the Tax Injunction Act and the Rooker /Feldman doctrine.
First, the statutory limitations of the Tax Injunction Act are not jurisdictional; rather, they define the scope of remedies a federal court may grant in a suit challenging taxes levied under state law.
See
28 U.S.C. § 1341. Second, although the
Rooker /Feldman
doctrine does indeed involve a jurisdictional issue;
see Facio v. Jones,
. It is on the basis of this holding in Cory that we grant the plaintiffs’ motion to dismiss the claims against the state agencies.
. This interpretation of the
Ex parte Young
doctrine sheds light on why an official-capacity suit against a state official is not always blocked by the Eleventh Amendment.
See Kentucky v. Graham,
. On the basis of Pennhurst, we grant the plaintiffs’ to dismiss their state law claims.
. Justice Kennedy wrote the principal opinion for the Court, but key provisions of his opinion garnered only one other vote.
See Coeur d’Alene Tribe,
. We note that the 4-R Act is not the appropriate statute on which to make a comparison between the remedy available under Ex parte Young and the statutory remedies that Congress otherwise has circumscribed. In this case, the natural gas pipelines do not come within the scope of the 4-R Act because they do not possess the "rail transportation property” that is the subject of the 4-R Act. See 49 U.S.C. § 11501(a)(3). Hence, relief is not being sought under the 4-R Act nor does that act purport to limit the natural gas pipelines' claims asserted here under the United States Constitution.
. Our conclusion on this question should not be interpreted as suggesting anything about the nature of the criteria for prospective injunctive relief in the opposite context when the state has failed to provide a plain, speedy, and efficient remedy. In that situation, which we do not face here, it may well be that the criteria for a remedy under Ex parte Young and the Tax Injunction Act are coextensive.
. It is worth pointing out that Congress enacted the Tax Injunction Act in part as a response to the Court’s fashioning of the
Ex parte Young
remedy that allowed injunctive suits against state officials.
See Rosewell,
. We do note, however, that a state’s sovereign power to tax its citizens has been a hallmark of the western legal tradition. This historical fact was clearly in the mind of the Framers when they considered the intertwining doctrines of sovereign immunity and a state's power to tax its citizens. As Alexander Hamilton explained in The Federalist,
I am willing here to allow, in its full extent, the justness of the reasoning which requires that the individual States should possess an independent and uncontrollable authority to raise their own revenues for the supply of their own wants. And making this concession, I affirm that (with the sole exception of duties on imports and exports) they would, under the plan of the convention, retain that authority in the most absolute and unqualified sense; and that an attempt on the part of the national government to abridge them in the exercise of it would be a violent assumption of power, unwarranted by any article or clause of its Constitution.
The Federalist,
No. 32 (A.Hamilton). This view of the singular importance of tax administration for the states recently was reiterated by the Court: "We have long recognized that principles of federalism and comity generally counsel that courts should adopt a hands-off approach with respect to state tax administration.”
National Private Truck Council, Inc. v. Oklahoma Tax Comm'n,
. The pipelines vehenjently argue that their requested relief will not impose a drain on the treasury of the state of Kansas because the property taxes actually are collected and retained by the local counties. They further affirmatively waive any claim in their suit that might be interpreted as a request for money damages against the state. It appears, however, that a portion of the property taxes collected by the counties are passed along to the state to fund some state education programs, and the state defendants contend that this fact means the pipelines are requesting a money judgment against the state. Despite the vigor of the parties’ argument on this issue, we need not determine the particular downstream location of the disputed property tax revenues. The question under
