This appeal questions the district court’s dismissal of plaintiffs’ constitutional attack on a municipality’s taking of their property by eminent domain because condemnation proceedings were pending in state court.
I.
Plaintiffs are property owners in the Village of Rosemont, Illinois, a suburb of Chicago, Illinois. Defendants are the Village of Rosemont and the individual members of its board of trustees. The Village is a unit of local government possessing home rule powers under the constitution and laws of the State of Illinois.
On October 30, 1973, the Village, through its board of trustees and pursuant to article VII of the Illinois Constitution of 1970, adopted Ordinance No. 73-10-30 granting itself eminent domain power as a home rule unit. On that same day, the Village adopted Resolution No. 73-10-30A authorizing it to acquire property by eminent domain for the construction of an athletic and convocation center. The resolution authorized the Village to file condemnation actions in state court to acquire the desired land.
Pursuant to this resolution, the Village instituted condemnation proceedings in state court against various property owners in the Village, including the plaintiffs. While these proceedings were pending, plaintiffs brought this action in federal district court seeking to stop the taking of their property. Plaintiffs brought this action under 42 U.S.C. § 1983 and invoked jurisdiction under 28 U.S.C. §§ 1331 and 1343 requesting injunctive, declaratory and monetary relief. Plaintiffs claim that the Village resolution authorizing the condemnation of their homes violates the fifth and fourteenth amendments of the Constitution in that it permits a taking for a private and not a public purpose. 1 Plaintiffs also maintain that section 9.7 of the Illinois Eminent Domain Act, Ill.Rev. Stat., ch. 47, § 9.7 (1975), 2 is unconstitutional because it prohibits the consideration of the proposed commercial use of the acquired property in computing “just” compensation. Plaintiffs seek to have the resolution and section 9.7 declared unconstitutional and the Village enjoined from continuing the state court condemnation proceedings under the authority of the resolution. 3
*196 Upon motion of the defendants, the .district court dismissed the action against the Village on grounds that a municipality is not a “person” under 42 U.S.C. § 1983 4 and against the trustees for reasons of comity. The district court opined that “[a] civil rights action . is not appropriate . . . in an eminent domain controversy when there is ongoing litigation in State Court where the Plaintiffs’ constitutional claims can be fully and fairly heard.” District Court’s Memorandum Decision and Order at 2. From this order of dismissal, plaintiffs appeal. We affirm.
II.
Ordinarily, when a litigant properly invokes one of the statutory grants of federal jurisdiction, a federal district court must assume and exercise jurisdiction over the litigant’s claims.
FSLIC v. Krueger,
The Supreme Court in
Mitchum v. Foster,
“we do not question or qualify in any way the principles of equity, comity, and federalism that must restrain a federal court when asked to enjoin a state proceeding.” [407 U.S. at 243 ,92 S.Ct. at 2162 .]
A year earlier, the Court described these “principles of equity, comity and federalism” in
Younger v. Harris,
“a proper respect for state functions, a recognition of the fact that the entire country is made up of a Union of separate state governments, and a continuance of the belief that the National Government will fare best if the States and their institutions are left free to perform their separate functions in separate ways.” [Id. at 44,91 S.Ct. at 750 .]
Federalism, the Court noted, represents:
“a system in which there is sensitivity to the legitimate interests of both State and National Governments, and in which the National Government, anxious though it may be to vindicate and protect federal rights and federal interests, always endeavors to do so in ways that will not unduly interfere with the legitimate activities of the States.” [Id.]
These principles of equity, comity, and federalism lie at the heart of the judge-made doctrine of abstention first
*197
fashioned in
Railroad Commission v. Pullman Company,
A.
Central to the concerns prevalent in the principles of equity, comity, and federalism is the strong desire to avoid unnecessary interference and conflict with the sovereignty of the states.
5
A logical corollary of this is that a federal court should refrain from interfering in ongoing state proceedings.
6
See Glen Oaks Utilities, Inc. v. City of Houston,
*198
The discretion possessed by the district courts to interfere with state court proceedings “should be exercised in the light of the historical reluctance of federal courts to interfere with state judicial proceedings.”
Southern California Petroleum Corp. v. Harper;
This respect and concern arises clearly in relation to a state’s eminent domain system. In
Louisiana Power & Light Company
v.
City of Thibodaux,
“[T]he principal and essential issue is one properly for determination by the state courts. Not only is municipal eminent domain ordinarily a local matter, but it is difficult to imagine a situation where more confusion would arise than would be the case if the parties here were allowed to simultaneously pursue both this action and the state condemnation proceeding. [Id. at 779.]
Accord,
Georgia v. City of Chattanooga,
The fact that plaintiffs here raise federal constitutional claims against the Illinois eminent domain system does not preclude abstention. The Supreme Court in
Mitchum v. Foster, supra,
noted that section 1983, while an exception to the ban of section 2283, did not necessarily mandate the exercise of federal jurisdiction where the principles of equity, comity and federalism dictated otherwise. And the Court has approved abstention in other cases where federal constitutional claims were before a federal court.
See, e. g., Harrison v. NAACP, supra; Askew v. Hargrave,
The presence of a federal constitutional claim in the federal court action does not preclude that court’s staying its hand because, as this court and others have repeatedly stated in the past, “we must assume that an Illinois court would properly determine the merits of any federal issue properly presented to it.”
Cousins v. Wigoda,
*199
Illinois eminent domain procedure allows condemnees to question the public nature of the taking and to raise other defenses in the form of a “traverse” or motion to dismiss the condemn- or’s petition. Ill.Rev.Stat., ch. 47, § 10;
Board of Education v. City of Chicago,
Furthermore, we believe that the mere existence of a federal constitutional attack on an eminent domain proceeding of the state should not be grounds for a district court’s decision not to abstain. Since there is a “possibility of a federal question in every taking by eminent domain under state authority,” Nichols, Law of Eminent Domain, § 413(2) (1973), such a factor would nearly always preclude abstention in this type of case. 9
Plaintiffs have the state courts of Illinois with its appellate system at their disposal for the adjudication of their federal constitutional claims.
See
Ill.Rev. Stat., ch. 47, § 12. If the Illinois Supreme Court should deny them “any rights secured to [them] by the Constitution and laws of the United States,” the case may be brought to the Supreme Court of the United States for reexamination and review.
Georgia v. City of Chattanooga, supra,
B.
Other circumstances are present which dictate that the district court abstain from deciding the constitutional claims before it. The doctrine of abstention emanating from the Supreme Court’s decision in
Railroad Commission v. Pullman Company,
“Regard for the interest and sovereignty of the state and the reluctance needlessly to adjudicate constitutional issues may require a federal District Court to abstain from adjudication if the parties may avail themselves of an appropriate procedure to obtain state interpretation of state laws requiring construction.”
Zwickler v. Koota,
Plaintiffs argue that section 9.7 of the Illinois Eminent Domain Act does not permit the consideration of the proposed “commercial” use for the condemned property in computing the amount of compensation, and therefore violates the due process clause’s requirement of “just compensation.” Assuming, arguendo, that due process requires the consideration of the condemned property’s proposed “commercial” use, we believe section 9.7 is clearly susceptible to such an interpretation by the Illinois courts. The question has not been reached by the Illinois Supreme Court. The state court in the condemnation proceedings may well interpret section 9.7 to allow the consideration of the Village’s proposed “commercial” use of the condemned property in determining the amount of compensation. 11
Since “the state court’s interpretation of the [statute] may obviate any need to consider [its] validity under the Federal Constitution, the federal court should hold its hand, lest it render a constitutional decision unnecessarily.”
City of Meridian
v.
Southern Bell Tel. & Tel. Co.,
III.
It is clear from all of this that the district court properly stayed its hand and refrained from interfering with the eminent domain proceedings pending in the Illinois courts. Where a district court abstains in deference to pending state proceedings so as not to interfere with state sovereignty, the proper disposition of the matter is dismissal.
Crawford v. Courtney,
Affirmed.
Notes
. In their federal complaint, plaintiffs also attack the resolution as violative of the fifth and fourteenth amendments because it permits the taking of residentially-zoned property for a commercial use. The ordinance was also attacked for lacking “sufficiently definite standards by which the proposed commercial uses are to be operated and managed in the public interest.” See note 7 infra.
. That section reads:
Except as to property designated as possessing a special use, the fair cash market value of property in a proceeding in eminent domain shall be the amount of money which a purchaser, willing but not obligated to buy the property, would pay to an owner willing but not obligated to sell in a voluntary sale, which such amount of money shall be determined and ascertained as of the date of filing the petition to condemn. Provided, that in the condemnation of property for a public improvement there shall be excluded from such amount of money any appreciation in value proximately caused by such improvement, and any depreciation in value proximately, caused by such improvement. Provided further, that such appreciation or depreciation shall not be excluded where property is condemned for a separate project conceived independently of and subsequent to the original project.
Ill.Rev.Stat., ch. 47, § 9.7.
. Plaintiffs’ federal complaint asked the district court to, inter alia:
Issue a permanent and final injunction restraining the Defendants, and each of them, and their officers, agents, servants and representatives from enforcing or attempting to enforce the ordinance or ordinances authorizing the condemnation of Plaintiffs’ real property.
Since all the parties to the federal action were at that time parties to the pending state court condemnation proceedings, plaintiffs were in effect seeking to enjoin the state proceedings by the relief sought in federal court. Our decision, however, is not premised on the seeking of injunctive relief; the seeking of declaratory *196 relief is sufficient interference with the state court proceedings to warrant the district court’s staying its hand. See note 6 infra.
Since plaintiffs sought only a declaratory judgment concerning section 9.7 of the Illinois Eminent Domain Act and not an injunction^ the convening of a three-judge court under 28 U.S.C. § 2281 was not required. See
Steffel v. Thompson,
. The district court further found that plaintiffs had failed to allege the requisite $10,-000.00 in controversy in order to invoke the court’s jurisdiction over the Village under 28 U.S.C. § 1331. The court denied the plaintiffs’ request for leave to amend their complaint to allege the requisite amount in controversy.
. This concern toward avoiding interference with another sovereign cuts both ways. The Supreme Court has held that state courts may not interfere with the sovereignty of the federal government in various contexts. See Redish & Woods, Congressional Power to Control the Jurisdiction of Lower Federal Courts: A Critical Review and a New Synthesis, 124 U.Pa.L.Rev. 45, 81-93 (1975).
. “Interference” encompasses more than one court’s enjoining the proceedings of another court. Nearly all of the cases in this area involve declaratory as well as injunctive relief. Declaratory relief has been generally regarded as to be as objectionable in this context as injunctive relief. See 1A Moore’s Federal Practice, jl 0.220, at 2603:
“In the exercise of discretion a federal court should normally deny a declaratory judgment where the issues raised may be fully adjudicated in a suit pending in a state court at the time the federal declaratory judgment action is instituted.”
See also Jones v. Steiner,
. Federal courts have also noted that the application of zoning ordinances and regulations is “distinctly a feature of local government” which is “outside the general supervisory power of federal courts.”
Hill v. City of El Paso,
. We note also that the Illinois Constitution of 1970 protects these plaintiffs. Article I, section 15 requires all takings by eminent domain to be for a public purpose and guarantees all condemnees “just” compensation. The Illinois Eminent Domain Act provides the same. 111. Rev.Stat., ch. 47, § 1.
. Plaintiffs’ readings and reliance on our decisions in
Progress Development Corp. v. Mitchell,
.
See also Huffman v. Pursue, Ltd.,
“[Wjhere a final decision of a state court has sustained the validity of a state statute challenged on federal constitutional grounds, an appeal to this court lies as a matter of right. 28 U.S.C. § 1257(1).”
. Plaintiffs maintain that section 9.7 is clear and unambiguous and susceptible to but one interpretation: the one they proffer. We disagree. It is true that the mere absence of a state court decision interpreting a state statute does not alone require abstention. But where the statute, as here, has not been construed and is susceptible to at least two interpretations, the absence of a state court decision interpreting it must be accorded great weight in deciding whether to abstain. P. Bator, D. Mishkin, D. Shapiro, & H. Wechsler, Hart and Wechsler’s The Federal Courts and the Federal System 991 (2d ed. 1973).
This case therefore is different from the decision in
Joiner v. City of Dallas,
. Because we find that the district court properly stayed its hand, we need not address plaintiffs’ argument that they should have been granted leave to amend their complaint to allege the requisite $10,000.00 in controversy. See note 4 supra.
