PUBLIC SERVICE COMPANY OF NORTHERN ILLINOIS
v.
CORBOY, DRAINAGE COMMISSIONER OF THE CALUMET DITCH.
No. 258.
Supreme Court of United States.
Argued March 20, 1919.
Decided June 2, 1919.
APPEAL FROM THE DISTRICT COURT OF THE UNITED STATES FOR THE DISTRICT OF INDIANA.
Mr. Buell McKeever, with whom Mr. Charles W. Smith, Mr. Gilbert E. Porter and Mr. William G. Beale were on the briefs, for appellant.
Mr. John H. Gillett and Mr. Frank B. Pattee, with whom Mr. Randall W. Burns was on the brief, for appellee.
*157 MR. CHIEF JUSTICE WHITE delivered the opinion of the court.
An "Act concerning drainage," passed in Indiana in 1907, briefly outlined is as follows: (1) It authorized the appointment by the county commissioners of each county of an officer called a drainage commissioner and made the county surveyor also ex officio such an officer. (2) It empowered a defined circuit court, on the petition of private land owners or of municipal or other public bodies representing public ownership, to establish a drainage district and to authorize the carrying out in such district of the work petitioned for, and gave the court authority to appoint an additional drainage commissioner, the three being directed to aid the court to the extent by it desired in securing data concerning the questions required to be passed upon in disposing of the petition. (3) To accomplish the purposes of the statute, personal notice to known property holders and notice by publication to those unknown was exacted, and the court was empowered to reject the whole suggested scheme or to authorize such part *158 of it as might be deemed best, or to devise and sanction a new plan. (4) As to any plan which it authorized, the court was empowered to provide for the cost of the work by distributing the amount upon the basis of the benefits to be received and the burdens to result to each land owner. (5) It authorized the designation by the court of one of the drainage commissioners, or if it deemed best, of any other resident of the district, to carry into execution under the general supervision of the court any work authorized, with power to contract and subject to accountability to the court as the work progressed and at its conclusion.
The Little Calumet River, rising in the State of Indiana, flows in a westerly direction across Porter and Lake Counties in that State into Cook County, Illinois, within whose boundaries it commingles with the Grand Calumet which empties into Lake Michigan.
After proceedings under the statute, the circuit court of Porter County, in May, 1911, established a drainage district in Porter and Lake Counties and authorized the construction of a ditch to proceed from the Little Calumet River in a northerly direction to Lake Michigan. This action of the court was taken to the Supreme Court of Indiana and there affirmed (182 Indiana, 178), and on error from this court was also affirmed (242 U.S. 375).
Before work on the ditch was commenced, however, the appellant, an Illinois corporation which was not a party to the proceedings to establish the district, brought this suit against Corboy, the drainage commissioner appointed by the court to do the work, to enjoin the execution of the same. The relief prayed was based on the ground that the effect of the ditch would be to draw off from the Little Calumet River, an interstate stream, such a quantity of water as to seriously diminish the flow in that river and thereby practically cripple, if not destroy, *159 the capacity of petitioner to continue to operate a plant for the production of electrical energy established and owned by it on the banks of the Little Calumet in Cook County, Illinois. It was alleged that the right to have the river flow in its normal volume was a property right enjoyed by petitioner under the law of Illinois, protected by the constitutions both of the State and of the United States, and which therefore could not be impaired or taken away without depriving the petitioner of property in violation of due process of law as afforded by both constitutions. The court, being of opinion that the relief prayed was prohibited by § 265 of the Judicial Code, dismissed the bill for want of jurisdiction. The case is here by direct appeal on that question alone.
Although a State may not be sued without its consent, nevertheless a state officer acting under color of his official authority may be enjoined from carrying into effect a state law asserted to be repugnant to the Constitution of the United States even though such injunction may cause the state law to remain inoperative until the constitutional question is judicially determined. The doctrine is elementary, but we refer to a few of the leading cases by which it is sustained: Pennoyer v. McConnaughy, 140 U.S. 1, 9; Reagan v. Farmers' Loan & Trust Co., 154 U.S. 362, 392; Ex parte Young, 209 U.S. 123, 152; Prentis v. Atlantic Coast Line Co., 211 U.S. 210, 230; Home Telephone & Telegraph Co. v. Los Angeles, 227 U.S. 278; Greene v. Louisville & Interurban R.R. Co., 244 U.S. 499, 506.
There was jurisdiction therefore in the court below as a federal court to afford appropriate relief unless the want of power resulted from the prohibition of § 265 of the Judicial Code, which is as follows:
"The writ of injunction shall not be granted by any court of the United States to stay proceedings in any court of a State except in cases where such injunction *160 may be authorized by any law relating to proceedings in bankruptcy."
In Prentis v. Atlantic Coast Line Co., 211 U.S. 210, the facts, briefly stated, were these: By the constitution and laws of Virginia the Corporation Commission of that State was constituted a court and was authorized in that capacity to establish railroad rates and to enforce them. The authority thus conferred was exerted and the jurisdiction of a court of the United States was invoked to enjoin the Commission from enforcing the rates so fixed on the ground that to put them in operation would amount to a confiscation of the property of the railroad and hence would be repugnant to the Constitution of the United States. The power to afford relief was challenged on the ground that as the Corporation Commission was a court under the constitution and law of the State, its proceedings could not be stayed by a court of the United States because of the prohibition of § 265 of the Judicial Code. It was held, however, that as the power to fix rates was legislative and not judicial, the prohibition had no application and the injunction prayed was granted.
In Simon v. Southern Ry. Co., 236 U.S. 115, suit was brought in a court of the United States by the Railway Company against Simon to enjoin the enforcement of a judgment which had been rendered in a state court in favor of Simon and against the Railway Company on the ground of want of notice and fraud. Asserting that to grant the relief would be to stay proceedings in the state court, the jurisdiction was disputed, based upon the prohibition of the section previously quoted. The jurisdiction was upheld and it was decided that although the prohibition might have prevented the granting of an injunction staying proceedings before the judgment was rendered, it did not so operate after the entry of the final judgment because "when the litigation has ended and a final judgment has been obtained  and when the plaintiff endeavors *161 to use such judgment  a new state of facts, not within the language of the statute may arise." The execution of the judgment was therefore enjoined.
This conclusion was sustained by the text as elucidated by the purely remedial purposes intended to be accomplished by its enactment. The court thus stated the origin of the statute as illustrative of its remedial scope (pp. 123-4):
"In 1793, when that statute was adopted (1 Stat. 334), courts of equity had a well-recognized power to issue writs of injunction to stay proceedings pending in court,  in order to avoid a multiplicity of suits, to enable the defendant to avail himself of equitable defenses and the like. It was also true that the courts of equity of one State or country could enjoin its own citizens from prosecuting suits in another State or country. Cole v. Cunningham, 133 U.S. 107. This, of course, often gave rise to irritating controversies between the courts themselves which could, and sometimes did, issue contradictory injunctions.
"On principles of comity and to avoid such inevitable conflicts the act of 1793 was passed."
Be this as it may, it is certain that the prohibitions which the statute imposes secure only the right of state courts to exert their judicial power; that is, a power called into play alone between parties to a controversy, and the operation of which power when exerted was, from the very fact that it was judicial, confined to the parties, their duties, interests and property, in other words, to a power falling within the general limitation of things judicial as demarked by the great distinction between legislative, executive and judicial power upon which the Constitution was framed. This is the necessary result of the ruling in the Prentis Case, by which it is made certain that although a State may have power to confer upon its courts such authority as may be deemed appropriate, it cannot by *162 the exertion of such right draw into the judicial sphere powers which are intrinsically legislative and executive or both, and thus bring the exercise of such powers within the scope of the prohibition of the statute, with the result of depriving the courts of the United States to that extent of their omnipresent authority to enforce the Constitution.
It follows necessarily, therefore, that although the Constitution did not limit the power of the States to create courts and to confer upon them such authority as might be deemed best for state purposes, that right could not, by its exertion, restrain or limit the power of the courts of the United States by bringing within the state judicial authority subjects which in their constitutional sense were non-judicial in character and therefore not within the implied or express limitation by which courts of the United States were restrained from staying judicial proceedings in state courts. To hold to the contrary would be in large measure to recognize that the exertion of the authority of the courts of the United States was dependent, not upon the nature and character of the subject-matter with which they are called upon to deal, but merely upon a state classification.
This conclusion renders it unnecessary to consider whether the construction of the ditch under the authority of the state statute, isolatedly considered, could be regarded as a judicial proceeding within the meaning of the statute, or whether, putting that view aside under the assumption that the proceedings were judicial, the order for construction could be treated as final and for that reason alone capable of being stayed, within the ruling of Simon v. Southern Ry. Co.
The arguments at bar pressed upon our attention considerations based upon the assumed application of general principles of comity, but as on this direct appeal we have power alone to consider questions of the jurisdiction of the court below as a federal court, they are not open to our *163 consideration. Louisville Trust Co. v. Knott, 191 U.S. 225. This moreover puts out of view the argument advanced concerning the adequacy of the averments of the bill to justify relief, since that subject necessarily, for the reasons stated, must be left to the consideration of the court below when it exercises jurisdiction of the cause.
Our order, therefore, is that the decree be reversed and the case be remanded for further proceedings in conformity with this opinion.
Reversed.
