delivered the opinion of the court.

' In 1870 certain suits were pending in the Circuit Court of the’ county of Elizabeth, City, Virginia, brought by judgment creditors of one Parker West to subject his lands to the satisfaction of their judgments, under the provisions of c. 182 of the code of 1873, authorizing a sale of the judgment debtor’s lands when it appeared that the .rents and profits for five years would be insufficient to discharge the liens against them. These causes were consolidated, and proceeded to decrée in September, '1870, for an account of all the real" estate -of said West, its annual value, and the liens thereon, under which a report was made by a commissioner showing the judgments against West and the lands belonging to him and their annual and fee-simple *179 value, ancl that the rents and profits-would not satisfy the liens in five years, which report was confirmed by decree entered May 4, 1871, which also appointed special commissioners to sell said lands, including “ all the interest of Parker West in that certain tract of land known as ‘ Newport Newrs,’ contain-' ing 300 acres,” etc. This land had been sold June 30, 1864, upon proceedings against West under the confiscation act of July 17, 1862, and a deed had been executed and delivered to the purchasers February 15, 1865. . No such proceedings had taken place in reference to other lands of West involved in the litigation, and one of the judgments counted on had been recovered as early as 186Í/ West died in December, 1871, and on the-4th of May, 1872, the following decree was entered in said consolidated cause:

“The death.of Parker West being suggested, on the motion of William P. Marrow and Mary E. his wife, Elizabeth It. West, George B. West, and M. Smith and Missouri, his wife, the said Mary E. Marrow, Elizabeth B. West, G. B. West and Missouri Smith being the heirs at law of the said Parker West, to be made parties defendant to these causes, the- said William P. Marrow and M. E. his wife, E. B-. West, G. B. West, and M. Smith and Missouri, his wife, are hereby made parties defendant to these causes, with leave to file their' answers. This’ cause then, this day, again came on to be heard oh the papers formerly read and on th° report of Special Commissioners C. It. Mallory, Thomas Tább and G. M Peek-of the sales made by them under a. former decree in these causes, to which report no exceptions'have been filed, and was argued by counsel. On consideration whereof the court doth adjudge, order and decree that the said report and the sales reported therein be, and the same are hereby,, confirmed.”

The sale of a portion of the Newport. News land'in controversy here was confirmed bv that decree, and thé sale of the remainder was made thereafter, and reported to the court, ahd the sale confirmed in October,' 1872.

In January, 1886, W.- P. 'M-arrOw ana- Mary E. his wife George B. Wesst, and Missouri "Smith-filed -their bill’ óf complaint in the state Circuit- Ca'urt, séeking to set -aside- the *180 decrees of May 4, 1871, and May 4, 1872, and the deeds which had been made to purchasers of lands thereunder; insisting that West’s title had been divested by the confiscation proceedings, and alleging that they never appeared in said consolidated causes in person, or employed any attorney at law to represent them, and that no process was ever served upon them, and charging fraud in the entry of their appearance. •

Upon the final hearing their bill was dismissed, and they prosecuted, an appeal to the Supreme Court of Appeals of Virginia, which court affirmed the decree of the court below, holding that, as between the heirs and the purchasers, the former were bound by the. recitals of the decree of May 4, 1872'; and that upon the evidence aliunde the record, the heirs wére estopped by laches and by conduct, to claim title as against the purchasers who were such in good faith for value and without notice. The complainants filed a petition for rehearing in the Court of Appeals, in which they staceu “ that on. the 17th day of May, 1888, in the aboye-entitled cause a decree was entered simply -affirming tlie decree of the lower court entered on the 26th day of October, 1886, dismissing the bill of the plaintiffs below for reasons stated in the opinion of the court. The reasons stated are based upon the equitable doctrine of estoppel in pais and innocent- purchaser for value, without notice, the language of the opinion upon these points-being as follows: (a) ‘ Having kept a sinister silence. when they should have spoken with candor and courage, equity now closes her door and leaves them to ohtaiq. from a court of law what they can.’ (b) cThat as against an innocent purchaser for value, without notice, a court of equity is without jurisdiction, and will refuse to give any assistance whatever, leaving the party to enforce his technical rights at- law.’ ” The rehearing was denied, and the writ of error sued out of this court, a motion to dismiss which is now before us. In the petition for the allowance of this writ it is said that the final judgment of the Court of Appeals against plaintiffs in error was rendered in a suit “wherein was drawn in question a right, title, privilege and immunity to real estate arising upon the construction of the act of Congress of the United States approved July 17, *181 1862, entitled ‘An act to suppress insurrection, to punish treason and rebellion, to seize and confiscate’ the property -of rebels, and for other purposes,’ and the joint resolution passed concurrently therewith, and the decision is against the right, title, privilege and immunity claimed under the said statute.”

"We do not so understand this record. Conceding that West’s title to the particular lands had been divested by the sale under the confiscation proceedings, and that the interest of the heirs remained unaffected -thereby, yet, if they were concluded under the circumstances by the decree of May, 1872, or upon the principles of estoppel and laches, that disposed of their case adversely to them; and it was upon these grounds that the Virginia courts proceeded, and not upon any decision against a right, title, privilege and immunity claimed under the Constitution or any statute of, or authority exercised under, the United States. It was only if the decision had been otherwise upon these points that any question could have arisen as to the validity of the confiscation act' and resolution and the-proceedings thereunder.

Unless it appears affirmatively that' the decision of a Federal question was-necessary to the determination of the cause, and that it was actually decided, or that the judgment as rendered could not have been given without deciding it, this court has no jurisdiction of a writ of error to a state court. In this case the judgment as rendered involved the decision of no such question, and none such was actually decided.

Nor can jurisdiction be retained upon 'the suggestion, made for the first time in this court, that if the Court of Appeals, proceeding upon the principles of - general law only, were found to have erred in the rendition of its decree, the State of Virginia had thereby depriyed the plaintiffs in error of their - property without due process.

The writ of e"~'or is dismissed.
