delivered the opinion of the court.
This is a direct appeal to this court, under the act of March 3, 1891, c. 517, § 5, from a decree of the Circuit Court of the United States for the District of West Virginia, dismissing for want of jurisdiction a bill in equity filed by Collis P. Huntington, a citizen of New York, as special receiver of the Central Land Company of West Virginia, a corporation of West Virginia, against John B. Laidley, a citizen of West Virginia, and against citizens' of other States, to charge a tract of 240 acres of land in that State with a trust.
The question of jurisdiction, and the aspect in which it was presented to the court below, will be best understood by first giving an outline of the undisputed facts, and of the proceedings in this case, as gathered from the voluminous record transmitted to this court.
On February 25, 1870, Sarah H. G. Pennybacker, a married woman, owning a tract of land of 240 acres in West Virginia, executed with her husband a deed thereof, with a separate acknowledgment by each, to Huntington, who on October 16, 1871, conveyed, his title therein to the Central Land Company; and that company afterwards, and before April, 1882, sold parts of the tract to one Remley and to other persons. The sufficiency of Mrs. Pennybacker’s acknowledgment was doubted;.and on January 26, 1882, she, having become a widow, executed and acknowledged, in due form of law, a deed of the tract to Laidley. All those deeds were duly recorded.
In April, 1882, Laidley brought, in the circuit court of Cabell county in the State of West Virginia, an action of ejectment against the Central Land Company to recover the tract of land; and a verdict and judgment obtained by the Central Land Company in that action were in November, 1887, set aside and reversed by • the Supreme Court of Appeals of West Virginia, and a new trial ordered, upon the ground that Mrs. Pennybacker’s acknowledgment to her first deed was defective. 30 West Virginia, 505.
*670The Central Land Companj7 filed in the county court in June, 1887, a bill in equity, and in March, 1888, an amended bill, against Laidley, Huntington, Mrs. Penny backer and the several grantees of the Central Land Company, alleging that Laidley obtained his deed from Mrs. Pennybacker by fraud, and held the land in trust for the Central Land Company, and should be restrained from proceeding with the action at law. The county court dismissed that bill, and its decree was affirmed in February, 1889, by the Supreme Court of Appeals. 32 West Yirginia, 134.
In September, 1890, the action of ejectment of Laidley against the Central Land Company (proceedings in which had been stayed to await the decision in the equity suit) was tried again in the county court, and a verdict and judgment returned for Laidley. A petition for a writ of error to review that judgment was afterwards denied by the Supreme Court of Appeals; and on March 26, 1891, the county court issued a writ of possession in favor of Laidley. A writ of error from this court to the Supreme Court of Appeals was sued out by the Central Land Company on July 7, 1891, and was dismissed by this court for want of jurisdiction on June 3, 1895. 159 U. S. 103.
In November, 1883, Laidley brought, in the county court separate actions of ejectment against Remley and the other persons who had taken deeds from the Central Land Company of parts of the tract of 240 acres. In each of those actions, the defendant filed a claim for improvements, and Laidley (pursuant to the provisions of the Code of West Yirginia of' 1891, c. 91, §§ 10-13) elected to allow the improvements, and on September 10, 1890, took judgment for the value of the lot recovered, with an order for its sale, instead of a judgment for the possession of the land, and for the transfer of the title. On December 15, 1890, the court appointed speciál commissioners to make the sales. On October 21, 1897, the court substituted, instead of those commissioners, William R. Thompson, and he advertised the lots for sale.
Meanwhile, on November 11, 1890, Huntington and others, *671stockholders in the Central Land Company, had filedr in the Circuit Court of the United States a bill in equity against the company to wind up its affairs, because its charter was-about to expire; and on the same day the court appointed Frank B. Enslow temporary receiver to take possession of all its property. On December 16, 1890, Enslow reported to the court that he had taken possession of all the property of the company, including the tract of 240 acres; and the court appointed Huntington special receiver, and directed Enslow to turn over all its property to him, which was accordingly done.
On February 28,1891, Huntington, as such special receiver, filed in the Circuit Court of the United States against Laidley, and against sundry persons claiming under grants from him, the bill in the present case, which set forth the convoyances from Mrs. Pennybacker to Huntington, from him to the Central Land Company, from that company to Rem ley and others,- from Mrs. Pennybacker to Laidley, and from him to the other defendants, and the appointment of. Huntington as receiver; alleged that the deed from Mrs. Pennybacker to Huntington was duly acknowledged by her, and was valid; and that Laidley’s acts, in obtaining the later deed from her to himself, and in conveying parts of the land to other persons, were .in fraud of the rights of the Central Land Company, and created a cloud upon the title of that company and of those claiming under it; and prayed for an injunction against the defendants from interfering with the plaintiff’s possession of the tract of 240 acres, and from doing any act tending to affect his title, or to cast a cloud upon it, and from proceeding to enforce any claim to, or taking possession of, or making any sales of, any of the lots sold by the Central Land Company; and further prayed that.the deed from Mrs. Pennybacker to Laidley, and his deeds to the other defendants, be declared void. On the filing of the bill, a temporary injunction was issued as prayed for.
On January 12,1892, a demurrer by Laidley to this bill, and a motion by him to dissolve the injunction, were both overruled. .
*672On January 26, 1894, the plaintiff filed an amended bill in this cause, repeating the allegations and prayers of the original bill; and further alleging-that, by reason of certain facts fully and specifically set forth, and alleged to have been discovered by the plaintiff since he filed the original bill, the acts of Laidley in procuring the deed to himself from Mrs. Pennybacker were done while he stood in a confidential relation to Huntington, and were fraudulentas against Huntington and the Central Land Company ; and also alleging that, if the legal title passed to Laidley by his deed from Mrs! Pennybacker, he and his grantees held the legal title in trust for the plaintiff and the grantees of the Central Land Company; and therefore praying that the defendants might be decreed to convey the lands, so held by them respectively, to Huntington as receiver of the Central Land Company, and to the grantees of that company.
On February 26, 1896, Laidley and the other defendants filed a plea and answer, in which they denied the allegations of the bill; set up by way of estoppel the judgments in the state courts in favor of Laidley and against the Central Land Company, in the action of ejectment, and in the suit in equity, between them; and claimed to. be allowed the amounts awarded to Laidley in his actions of ejectment against Eemley and others.
On December 26, 1896, the plaintiff was allowed to further amend his bill in particulars which need not be stated; and the defendants filed the same plea and answer to the bill as so amended.
On July 12, 1897, the court, upon a hearing of the parties, adjudged that “ said plea of res adjudicata ” be overruled ; and gave the defendants leave to answer the bill; and denied motions of the defendants to dissolve the injunction, and to remove Huntington from the office of receiver.
On July 13, 1897, Laidley filed another plea and answer, setting up, in different form, substantially the same defences as in the former plea and answer. On September 4, 1897, the 'other defendants filed an answer to that bill; and the plaintiff obtained an order on Laidley, returnable January 10, 1898, to show cause why his new plea and answer should not be stricken *673from the files as irregular. On October 4, 1897, the plaintiff filed a general replication to the answer of the other defendants.
On December 17, 1897, Huntington, as plaintiff in the case at bar, filed a petition in the Circuit Court of the United States for a rule against Laidley and against his attorneys, Z. T. Yinson and William R. Thompson, to show cause why they should not be fined and attached for contempt in violating the injunction granted by that court in February, 1891, by undertaking to sell the lots described in Laidley’s actions of ejectment against Remley and others. On December 20, 1897, Laidley and Thompson filed answers to this rule, and annexed thereto as exhibits copies of the proceedings in those actions Of ejectment.
On December 20, 1897, on motion of the plaintiff, the court extended the time for taking the testimony in the cause until ninety days after the hearing on the motion to strike out Laidley’s plea and answer.
On March 3, 1898, the rule for an attachment for contempt was argued. On June 25, 1898, the court entered an order discharging that rule, because, as the order stated, the court found that the circuit court of Cabell county, West Yirginia, had taken jurisdiction of the parties and the subject-matter, prior to the institution of this suit, and the cause was still pending in that court, and therefore the Circuit Court of the United States had no jurisdiction to grant the injunction restraining the sale of the property under decrees of the state court.
On the same day, and without any further hearing in the cause, the court, of its own motion, entered a final decree, as follows: “ This cause having come on this 25th day of June, 1898, to be considered by this court upon a petition filed by the complainant herein on the 17th day of December, 1897, praying that a rule be issued requiring that John B. Laidley, one of the defendants herein, and his attorneys, Z. T. Yinson and W. R. Thompson, should appear and show cause why they should not be fined and attached for contempt for violating the injunction order heretofore entered in the above entitled cause, and upon the answer and exhibits attached thereto of the said *674defendant, John B. Laidley, to said petition, and upon the answers and exhibits attached thereto of his attorneys, Z. T. Yinson and W. R. Thompson, thereto, and upon the bill and-the answers to said bill; and the court having considered the matter, and having duly examined the bill and- amended bills herein, and the answers of the defendant and the exhibits-attached thereto, and .the records in the ejectment suits in the circuit court-of Cabell county, in which John B. Laidley was plaintiff and the Central Land Company of West Yirginia and others were defendants, and the record in the chancery cause in the circuit court of Cabell county, in which the Central Land Company of West Yirginia was plaintiff and John B. Laidley and others were defendants, which said records in said state court actions were not disputed or denied by the complainant ; and it appearing from such examination to the satis-^ faction of this court, upon consideration thereof, that this suit doe$ not really and substantially involve a dispute or controversy properly within the jurisdiction of this court, because of the pendency in the state court, prior to the commencement of this suit, of the action of ejectment in which John B. Laidley was plaintiff and the Central Land Company of West Yirginia was defendant, which was begun in the circuit court of Cabell county, West Yirginia, on the first Monday of April, 1882, and of the other actions in ejectment brought in said state court by the said John B. Laidley as plaintiff in relation to the property in question in this suit, prior to the commencement of this cause, and of the chancery cause in said state court in which the Central Land Company of West Yirginia was plaintiff and John.B. Laidley and others were defendants, which was brought in said state court prior to the commencement of this cause; and this court being therefore, for the aforesaid reason, of the opinion that it is required to dismiss this suit by the fifth section of the act of Congress, approved. March 3, 1875, and entitled ‘An act to determine the jurisdiction of Circuit Courts of the United States, and to regulate the removal of causes from state courts, and for other purposes,’ it is now therefore, on this court’s own motion;adjudged and decreed that this suit and the bill and amended bills therein be,- and *675they hereby are, dismissed and stricken from the docket of this court, without costs.”
On the same day, the following proceedings took place, and were filed in the Circuit Court of the United States, namely: The plaintiff presented a petition for an appeal from that decree to this court, under the act of March 3, 1891, c. 517, § 5, alleging that he was aggrieved by the final decree by which the Circuit Court of the United States, notwithstanding that it had the first actual physical possession of the land involved in this cause, dismissed the suit on the ground that it had no jurisdiction thereof, because of the pendency of the suits in the state court, begun prior to' the commencement of this cause. And the District Judge signed an order “that the appeal be allowed- as prayed for; ” approved an appeal bond; and signed a citation to the appellees, as well as a certificate in these terms: “ A final decree having been entered herein on the 25th day of June,i1898, dismissing this suit and the bill and amended, bills therein: Now therefore this court, in pursuance of the second paragraph of the fifth section of the act of Congress, approved March 3, 1891, and entitled ‘ An act to establish Circuit Courts of Appeals, and to define and regulate in certain cases the jurisdiction .of the courts of the United. States, and for other purposes,’ hereby certifies to the Supreme Court of the United States for decision the question of the jurisdiction alone of this court over this cause, as follows: Is this court without jurisdiction of this cause, because of the pendency -in the state court, prior to the commencement of this suit, of the action of ejectment in which John B. Laidley was plaintiff and the Central Land Company of West Yirginia was defendant, which was begun in the circuit court of Cabell county, West Yirginia, on the first Monday in. April, 1882, and of the other actions in ejectment brought prior to this cause in said state court by the said John B. Laidley as plaintiff, in relation to the property in question in this suit, and of the chancery cause.in which the Central Land Company of West Yirginia was complainant and John B. Laidley and others were defendants, which was brought in said state court prior to the commencement of this cause ? ”
*676The appeal in this case is taken under that clause of the act of March 3, 1891, c. 517, § 5, which provides that appeals or writs of error may be taken from the Circuit Court of the United States directly to this court “in any case in which the jurisdiction of the court is in issue; in such cases the question of jurisdiction alone shall be certified to the Supreme Court from the court below for decision.” 26 Stat. 827.
The appellees have moved to dismiss the- appeal, upon the ground that the decree of dismissal involved the consideration and determination of the legal effect and conclusiveness of the several judgments and decrees of the state courts, and therefore the appeal should have been to the Circuit Court of Appeals, and not to this court; and upon the further ground that the District Judge could not certify a question decided by the Circuit Judge, or allow an appeal from his decree.
In order to maintain the appellate jurisdiction of this court under this clause, the record must distinctly and unequivocally show that the court below sends up for consideration a single and definite question of jurisdiction. This may appear in either of two ways; by the terms of the decree appealed from and of the order allowing the appeal; or by a separate certificate of the court below. Maynard v. Hecht, 151 U. S. 324; In re Lehigh Co., 156 U. S. 322; Shields v. Coleman, 157 U. S. 168; Interior Construction Co. v. Gibney, 160 U. S. 217; Van Wagenen v. Sewall, 160 U. S. 369; Chappell v. United States, 160 U. S. 499; Davis v. Geissler, 162 U. S. 290. In the case at the bar it appears in both ways.
The final decree of the Circuit Court of the United States recited that, at the hearing upon the petition for a rule for an attachment for contempt, the court examined the bill and amended bills and the answers thereto, and the undisputed records of the suits in the state court; and that from such examination it appeared to the satisfaction of the court that this suit did not really and substantially involve a dispute or controversy properly- within its jurisdiction, because of the pendency of those suits in the state court, and for that reason the court was of opinion that it. was required by section 5 of the act of March 3, 1875, c. 137, to dismiss the suit; *677and it was therefore, upon the court’s own motion, adjudged and decreed that the suit be dismissed. The act of March 3, 1875, c. 137, § 5, referred to in that decree, provides that if in any suit commenced in a Circuit Court of the United States, it appear to the satisfaction of that court, at anytime after-the suit is brought, “ that such suit does not really and substantially involve a dispute or controversy properly within the jurisdiction of said Circuit Court,” that court shall dismiss the suit. 18 Stat. 472. And such dismissal for want of jurisdiction is reviewable by this court under.the act of March 3, 1891, c. 517, § 5. Wetmore v. Rymer, 169 U. S. 115. The,final decree, therefore,'clearly shows that the question-decided below was a specific question of jurisdiction only. This dismissal of the suit for want of jurisdiction was the only' ground assigned for the appeal; and the appeal was allowed “as prayed for.”
The same question is also distinctly stated in the certificate made and filed by the District Judge on the same day on which the final decree was entered, and on which he allowed thje appeal and signed the citation. It does not appear from the record, and is immaterial, whether the final decree was rendered by the Circuit Judge or by the District Judge. The District Judge was a judge of the Circuit Court of the United States, and as such had a&thority to allow the appeal and to sign the citation, even if the decree was rendered by the Circuit Judge. Rev. Stat. §§ 999,1012; Rodd v.Heartt, 17 Wall. 354. We can have no doubt that the District Judge, who as a judge of the Circuit Court lawfully allowed the appeal and signed the citation, was authorized also to certify to this court the question of jurisdiction determined by that decree.
The question of jurisdiction- then, appearing by the decree itself and by the order allowing the. appeal therefrom, as well as by the distinct and contemporaneous certificate, to have been the only question on which the decree below was based, is rightly before this court for determination.
The condition of the cause, at the time when the Circuit Court of the United States entered a final decree dismissing it for want of jurisdiction, was as follows: An injunction *678had been granted upon the filing of the bill. The court had overruled a demurrer to the bill, as well as a plea of all the defendants setting up the judgments in the state courts as res ádjudieata; and had given leave to the defendants to answer the bill. Thereupon the deféndant Laidley filed a plea and answer setting up substantially the same defences as before; and the plaintiff obtained an order to show cause why this plea and answer should not be stricken out as irregular. The other defendants answered.the bill, and the plaintiff filed a general replication to their answer. The court extended the time for taking testimony in the cause until ninety days after hearing the motion to strike out Laidley’s plea and answer. That motion was never heard; the time allowed for taking testimony had not expired; and the cause was not heard, or ready to be heard, as between the plaintiff and any of the defendants, except upon a rule (which had been obtained by the plaintiff and argued by both parties) for an attachment against Laidley and his attorneys for contempt in violating the injunction previously granted. Yet the court not only discharged the rule for an attachment for contempt, but at the same time, of its own motion, and without any further hearing of the cause, or of any matter therein, entered the final decree dismissing the suit for want of jurisdiction. This action of the court was irregular. The defendant, as the case stood, was not entitled to present any objection to the jurisdiction of the court over the principal cause; and the plaintiff was entitled to be heard upon any such objection taken by the court of its own motion. Hartog v. Memory, 116 U. S. 588; Morris v. Gilmer, 129 U. S. 315, 327; Wetmore v. Rymer, 169 U. S. 115, 122, 123.
Independently of that consideration, the decree dismissing this suit for want of jurisdiction was erroneous. It may be that the order discharging the rule for an attachment for a contempt in violating the injunction by proceedings under orders of the state court was correct. Rev. Stat. § 720; Diggs v. Wolcott, 4 Cranch, 179; Riggs v. Johnson County, 6 Wall. 166, 195; Central Bank v. Stevens, 169 U. S. 432, 460. But it by no means follows that the.Circuit Court of the United *679States had no jurisdiction to entertain this suit for any purpose.
Before the commencement of the present suit, all'the proceedings between Laidley and the Central Land Company in the state court, which affected the whole tract of 240 acres, had been brought to an end — Laidley’s action of ejectment against the Central Land Company, by a judgment and a writ of possession in Laidley’s favor; and the Central Land Company’s bill to restrain Laidley from proceeding with that action, by a decree dismissing the bill.- And Laidley’s proceedings in ejectment in the state court against Remley and others concerned only the legal title in parts of the tract of 240 acres.
The present suit seeks to charge the whole tract with a trust in favor of the plaintiff as receiver of the Central Land Company. Under the circumstances of this case, the qúestion whether the proceedings in any or all of the suits, at law or in equity, in the state court, afforded a defence — either by way of res adjudicate or because of any control acquired by the state court over the subject-matter' — to this bill in the Circuit Court of the United States, was not a question affecting the jurisdiction of that court, but was a question affecting the merits of the cause, and as such to be tried and determined by that court in the exercise of its jurisdiction. The Circuit Court of the United States cannot, by treating a question of merits as a question of jurisdiction, enable this court, upon a direct appeal on the question of jurisdiction only, to decide the question of merits, except in so far as it bears upon the .question whether the court below had or had not jurisdiction of the case.
In any aspect of the case, the decree of the Circuit Court of the United States, dismissing'the suit for want of jurisdiction, must be reversed, and the cause remanded to that court for further proceedings therein.
The case of Blythe v. Hinckley, 173 U. S. 501, cited by the appellees, has no tendency to support .the opposite conclusion. In that case, this court dismissed the appeal, because the decree below was not founded solely upon a want of jurisdiction in .the Circuit Court of the United States, but also Upon the *680grounds that the plaintiff’s remedy was at law and not in equity, and that certain judgments of the state courts could not be reviewed on the reasons put forward. And of the last ground this court, speaking by the Chief J"ustice, said that it “ was not in itself a decision of want of jurisdiction because the Circuit Court was a Federal court, but a decision that the Circuit Court was unable to grant relief because of the judgments rendered by those other courts.’ 173 U. S. 507.
Decree reversed, and cause remanded for fu/rther proceedings.
