delivered the opinion of the Court.’
The appellant, by a bill filed in the District Court for Eastern Pennsylvania, sought to, enjoin the appellees, who are officials of the Commonwealth of Pennsylvania, from attempting to impose and collect an inheritance tax. Diversity of citizenship and an amount in controversy exceeding, exclusive of interest, $3,000, were averred. The bill sets forth that Thomas B. Clarke, a citizen and resident of the state of New York, died there in 1931 leaving a will under which appellant qualified as executor; that at and before the time of Clarke’s death there was on exhibition in Pennsylvania a collection of paintings owned by him, of the estimated market value at the date of his death of $714,750; that these paintings had been loaned *26 to the Pennsylvania Museum and School of Industrial Art, a non-profit corporation, so that they might be exhibited in the museum of that institution;' that the loan was negotiated orally and was for an indeterminate period, but the pictures were to be returned to Clarke at any time upon.his request. The bill then quotes the Act of Assembly of Pennsylvania 1 whereby a transfer inheritance tax of a specified percentage of value is laid upon transfers, by will or the intestate laws, of property located within the Commonwealth, from, a decedent not a resident of the Commonwealth at the time of his death; describes the procedure for the collection of the tax, namely, that the Department of Revenue, whenever occasion may require, shall appoint an appraiser to appraise the value of the property, if subject to tax; appraisement shall be made after notice to the interested parties; the appraiser shall report his valuation in writing to the Department of Revenue; whereupon that Department is required to give notice to all interested parties, and any person not satisfied with the appraisement may appeal to the Court of Common Pleas of Dauphin County, which may determine all questions of valuation and the liability of the appraised estate for the tax. The bill recites the appointment of an appraiser, who duly notified the appellant of the proposed date of his appraisement; the making .of a return, under protest, pursuant to instructions of the appellee Schnader, enumerating as property within the Commonwealth at the decedent’s death the seventy-nine portraits in question, and denying taxable situs or taxability, of the property in Pennsylvania; a hearing by the appraiser, who referred the question of taxability to the Department of Justice, of which the appellee Schnader is the head, and pending a decision by him postponed the appraisement indefinitely; and re *27 peated requests for an immediate determination of tax liability, in response to which the appellee Schnader orally advised the appellant its claim of nontaxability in Pennsylvania would be denied. The bill charges that if the statute be construed to impose an inheritance tax upon the paintings merely because they were temporarily within the Commonwealth at the time of the decedent’s death, it is unconstitutional- as depriving the appellant of property without due process and denying equal' protection of the laws, in contravention of the Fourteenth Amendment; and if the statute be construed as not applying to the property, the threatened appraisal, assessment and collection by the defendants will unconstitutionally deprive the appellant of property without due process and deny it equal protection. It further charges that the threat of appraisement, assessment and collection, and the unlawful failure and refusal of the appellee Metzger to issue a waiver of taxes on behalf of the Commonwealth, have caused and are causing irreparable injury by interfering with the administration of the estate in the. Surrogate’s Court of New York, preventing distribution, compelling the executor to maintain large cash reserves at a low rate of interest to cover a possible Pennsylvania tax and costs of litigation; and also that the threatened tax constitutes a possible lien and a cloud upon the title of the plaintiff, interfering with the sale of the paintings as directed by the will. The bill avers the absence of any adequate remedy at law.
A temporary injunction was issued, an answer was filed admitting the facts stated, and a statutory court of three judges was convened and heard the case on the pleadings and an agreed statement which is immaterial to the questions presented.
The answer asserted, and the court found, that the appellant had an adequate remedy at law, as it could appeal from the appraisement, when made, to the Dauphin *28 County court, which has jurisdiction to pass on both the amount of the tax and the legality of its imposition. The bill was therefore dismissed for want of equity.
1. It is conceded that neither the statutes of Pennsylvania nor the decisions of its courts permit an action at law for the recovery of a tax paid under protest. ■ If that procedure were permissible in the state courts, the appellant could pursue the same remedy in a federal court, ther.e being the requisite diversity of citizenship and amount in controversy.
Matthews
v.
Rodgers,
*29
The appeal must be entered in a state court specifically-designated by the statute, and is thus not an ordinary action at law, but a statutory proceeding. The Commonwealth has conditioned the right to implead it, upon resort'to a forum of its choice. The taxpayer cannot, therefore, though a non-resident, appeal from the appraisement to a federal court. Moreover, in such cases, upon the perfecting of an appeal, the Commonwealth becomes the adverse party to the litigation in the common pleas court

Taylor,

v.

v.
South Carolina,
2. Since the Dauphin County court is. empowered, upon appeal from the action of the appraiser, to determine all questions, including both valuation and liability for the tax, the contention is made that its function is at
*30
least in part administrative, and a suit for injunction may not be entertained by a federal court prior to the decision of the state court.

v.
Patterson,
“ The proceeding in the present case before the commissioners appointed to appraise the land was in the nature of an inquest to ascertain its value,' and not a suit at law in the ordinary sense of those terms. But when it was transferred to the District Court by appeal from the award of the commissioners, it took, under the statute of the State, the form of a suit at law, and was thenceforth subject to its ordinary rules and incidents. The point in issue was the compensation to be made to the owner of the land; in other words, the value of the property taken. No other question was open to contestation in the District Court.”

“ If, however, the presentation of a demand against the county, duly verified, according to law, to the county court thereof, ‘ for allowance or rejection ’ is not the beginning of ,a suit or does not involve a trial inter partes, it is then only a preliminary proceeding' to a suit or controversy which, by the appeal of either side, is or may be carried to an appellate court, before which there is an actual trial between the parties interested. The right to maintain this revisory trial in the state court . . . will be sufficient to maintain a like suit by original process in a federal court where the requisite divérse citizenship exists.”

Smith
v.
Douglas County,
If the Dauphin County court were by the act of Assembly granted only the right to revise the valuation of the appraiser, and precluded from considering any other question, its proceedings would be purely administrative, and the contention that the appellant had failed to pursue to the end its administrative remedy would be sound
(Upshur County
v.
Rich,
The court below relied upon
Keokuk & Hamilton Bridge Co.
v.
Salm,
The Acts of Assembly of Pennsylvania direct the Department of Revenue to collect, and the Attorney General to bring suit for, the amount of the tax, if it is not paid within one year of assessment. If, therefore, the appel *34 lant should omit to take an appeal to the Dauphin County common pleas court, the assessment would become final and the appellant liable to suit for the amount of the tax. 4 As the Commonwealth is the plaintiff in the action, the cause could not be removed, for reasons already stated.
We are of opinion that upon the making of the appraisement the administrative procedure is at an end, and the appellant can thereafter resort to a federal court of equity to restrain further action by the state officers if in violation of constitutional rights.
3. The question, then, is whether the bill was prematurely filed. In view of what has been said, the appellant’s cause of action in equity will not, strictly speaking, arise until an appraisement is made and certified to the Department of Revenue and notice of the fact is given appellant. Ho'wever, in view of the allegations of the bill, we are not inclined to hold the suit premature. The bill charges that the Secretary of Revenue has refused to issue a waiver of tax, and that the Attorney General has notified the appellant and the State’s appraiser the property is subject to the tax, and the appellant’s claim for exemption will be denied. The Commonwealth’s law officers plainly intend to perform what they consider their duty, and will, unless restrained, cause the assessment and imposition of the tax. The action the legality of which is challenged thus appears sufficiently imminent and certain to justify the intervention of a court of equity. Compare
