¶1delivered the opinion of the Court:
¶21. The question of the jurisdiction of a court of equity to entertain jurisdiction of a suit of this kind, in view of the provisions of section 3224 of the Revised Statutes of the United States, lies at the threshold of this case, and cannot be ignored. It has not, in fact, been ignored in argument by counsel on either side, although both sides fully concur in the desire that the jurisdiction should be sustained. The appellees, having appealed to the jurisdiction as complainants, very naturally are willing to abide by it; and the appellants, who have desired to be guided by the advice of the court in the premises, and who might possibly, in view of their peculiar functions, be entitled to apply to a court of equity for guidance in the performance of their rather difficult duty, are equally solicitous for some authoritative exposition of the doubtful provisions of the law with regard to that duty. But this concurrence of desire cannot give jurisdiction to the court of equity, unless it can be shown otherwise to exist. We think, however, that this is a case proper for the. cognizance of a court of ecpiity.
¶3Section 3224 of the Revised Statutes provides that “ no suit for the purpose of restraining the assessment or collection of any tax shall be maintained in any court.” This section was taken from the tenth section of the act of Congress of March 2, 1867 (14 Stat. 475), which was an amendment of the internal revenue act of July 13, 1866 (14 Stat. 98), itself an amendment of the acts of June 30, 1864 (15 Stat. 223), and March 3, 1865 (13 Stat. 4Ó9); and it is found in the revision among the provisions for the collection of the internal revenue of the United States, where special *207provision is made for the recovery of. taxes wrongfully levied. This would seem to indicate that it was not intended to apply to cases of special assessment, like that now before us, where it is not a question of the revenues of the United States, but to the matter of the ordinary taxes raised and intended for the support of the Government. A special assessment, it is true, is a tax, in the general sense of the term; but it is not such a tax as was contemplated by the statute that has been cited.
¶4The statute seems to be no more than what was already the doctrine of equity, ever since the decision in the case of Mooers v. Smedley, 6 Johns. Ch. 28, by Chancellor Kent. A court of equity will not interfere with the collection of taxes simply on the ground that the taxes are illegal. To warrant' the intervention of equity, as was said by the Supreme Court of the United States, in the case of Dows v. Chicago, 11 Wall. 109, by Mr. Justice Field, “there must exist in addition special circumstances bringing the case under some recognized head of equity jurisdiction, such as that the enforcement of the tax would lead to a multiplicity of suits, or produce irreparable injury, or, where the property is real estate, throw a cloud upon the title of the complainant.” But it is well settled that, where there are such special circumstances, equity will intervene, and the statute cited is no bar to the intervention.
¶5In the case of the Union Pacific Railway Company v. Cheyenne, 113 U. S. 516, 525, the Supreme Court of the United States, by Mr. Justice Bradley, said:
“It. cannot be denied that bills in equity to restrain the collection of taxes illegally imposed have frequently been sustained. But it is well settled that there ought to be some equitable ground for relief besides the mere illegality of the tax; for it must be presumed that the law furnishes a remedy for illegal taxation. It often happens, however, that the case is such that the person illegally taxed would suffer irremediable damage, or be subject to vexatious litigation, if he were compelled to resort to his legal remedy *208alone. For example, if the legal remedy consisted only of an action to recover back the money after it had been collected by distress and sale of the taxpayer’s lands, the loss of his freehold by means of a tax sale would be a mischief hard to be remedied. Even the cloud cast upon his title by a tax under which a sale could be made would be a grievance which would entitle him to go into a court of equity for relief.”
¶6In the case of Lyon v. Alley, 130 U. S. 177, 187, which went up from this District, the same high tribunal, speaking by Mr. Justice Lamar, said:
“ It is a well settled doctrine of this court that equity will not interpose to arrest the proceedings for the collection of a tax upon the sole ground of its illegality. It is equally well settled by the decisions of this court and the State. courts that, after the land has been sold and a conveyance of some sort made to the purchaser, courts of equity have inherent jurisdiction to give relief to the owner against vexatious litigation and threatened injury to the market value of the land, by removing the cloud which such illegal sale, and the illegal claim arising from it, may cast upon the title, and in such case of damage, either existing or apprehended, equity will interpose for relief, even during the progress of the proceedings before the sale.”
¶7To the same effect are the more recent cases of Gage v. Kaufman, 133 U. S. 471, and Rich v. Braxton, 158 U. S. 375, 405.
¶8The removal of a cloud from the title to land is, therefore, a well recognized ground of equity jurisdiction, when such cloud is the result of illegal taxation. The prevention of such a cloud is equally recognized. Prevention and removal are equally within the domain of the remedial processes of equity.
¶9Very applicable to the present, as well as to another aspect of the question, is what the Supreme Court of the United States, by Mr. Justice Harlan, said in the case of Rich v. Braxton, supra:
*209“ It must be remembered that ‘ it is not enough that there is a remedy at law; it must be plain and adequate, or, in other words, as practical and efficient to the ends of justice and its prompt administration as the remedy in equity.’ Boyce v. Grundy, 3 Pet. 210, 215; Drexel v. Berney, 122 U. S. 241; Allen v. Hanks, 136 U. S. 300, 311. And the applicability of the rule depends upon the circumstances of each case. Watson v. Sutherland, 5 Wall. 74, 79. In the case now before us it cannot be said that the invalidity of the deeds which the plaintiffs seek to have can-celled appears on their face. It is not clear that their invalidity can be placed beyond question or doubt without evidence dehors those deeds.
“ Besides, by the laws of West Virginia, the tax deeds under which the defendants claim ar& prima facie evidence against the owner or owners, legal or equitable, of the real estate at the time it was sold, his or their heirs or assigns, and all other persons who might have redeemed the same within .the time prescribed by law, and conclusive evidence against all other persons that the material facts recited in them are true. Code of W. Va. 1868, ch. 31, sec. 29, &c., Mr. Pomeroy, in his Treatise on Equity Jurisprudence, while recognizing it to be the general rule, established by the weight of authority, that equity will not interfere to remove a cloud from title, where the instrument or proceeding constituting the alleged cloud is absolutely void on its face, so that no intrinsic evidence is necessary to show its invalidity,’ or ‘ where the instrument or proceeding is not thus void on its face, but the party claiming, in order to enforce it, must necessarily offer evidence which will inevitably show its invalidity and destroy its efficacy’ — which doctrine, he says often operates to produce a denial of justice — correctly says, that equity will interfere, where deeds, certificates, and other instruments given on sales for taxes are máde by statute prima fade evidence of the' regularity of proceedings connected with the assessments and.sales. 3 Pomeroy’s Eq. Jur., sec. *2101399, and note 1, p. 437, and authorities there cited. And this view is sustained by numerous authorities. Huntington v. Central Pacific Railroad, 2 Sawyer, 503, 514; Allen v. City of Buffalo, 39 N. Y. 386, 390; Palmer v. Rich, 12 Mich. 414, 419; Marquette, H & O. Railroad Co. v. Marquette, 35 Mich. 504; Milwaukee Iron Co. v. Town of Hubbard, 29 Wis. 51, 58; Weller v. St. Paul, 5 Minn. 95; Pixley v. Huggins, 15 Cal. 127; Tilton v. O. C. M. Railroad Co., 3 Sawyer, 22. See also 2 Blackwell on Tax Titles, sec. 1066, and authorities cited. In the present case there are no defects of a controlling character that distinctly appear on the face of the tax deeds under which the defendants claim title. And as those deeds are made by a statute prima facie evidence of title in the grantees named in them, and as, therefore, the plaintiffs, if sued in ejectment by the defendants, would be compelled, in order to defeat a recovery against them, to resort to extrinsic evidence in support of their title, the deeds in question constitute a cloud upon that title, to remove which the plaintiffs may rightfully invoke the aid of a court of equity.”
¶10In the case now before us, the statute, under which the Park commissioners are acting, expressly makes their assessment a lien upon the land assessed, and precludes inquiry into the regularity or validity of the antecedent proceedings, precisely as in the case of Rich v. Braxton, and their action, therefore, necessarily operates to cast a cloud upon the property of the complainants, in respect of which they can have adequate relief only in equity. It is upon the ground that, by the assessment made and threatened to be enforced by the commissioners, a cloud would be cast upon their title to their real estate, and they would be subjected to vexatious litigation and irreparable injury, they expressly seek in their amended and supplemental bill the interposition of a court of equity to relieve them from what is alleged to be the imposition of illegal taxation. And we think, upon the authorities cited, and upon the general principles of equity, that they are entitled to it.
¶11*211It may be that they should have waited until the commissioners had definitely fixed the amount of the assessment upon their property, and had thereby completed the assessment. But this probably is a matter which the commissioners could have waived, as -they have actually waived it in their brief and in open court; and it is not apparent, under the peculiar circumstances of this case, that any good purpose would have been subserved by further delay. The commissioners had definitely announced their determination to assess the property in question ; in order to fix . the amount of the assessment, they required testimony to be taken, which might have involved much delay and expense ; and the testimony, when taken, would not have enlightened in any manner the question now at issue, which merely concerns the validity of the statute under which they are proceeding. The determination of the specific amount of the assessment would not have altered the record, or changed in any manner the rights of parties, so far as they are to be determined by this suit. The question now before us is not the amount of the assessment, but the right of the commissioners to make any assessment.
¶12It may be that this question of jurisdiction should be considered in another aspect also. The power conferred by the statute upon the Supreme Court of the District of Columbia “to hear and determine all matters connected with said assessment,” might perhaps be regarded as a special jurisdiction to be exercised only under the conditions and in the mode prescribed by the statute, and without appeal to this court, since no appeal is expressly provided by the statute itself. But courts of general jurisdiction, and especially courts of equity, are not ousted of their jurisdiction, or of any part of it, except by positive legislation absolutely inconsistent with its continued exercise. Sedgwick on Statutory and Constitutional Law, ch. 4 and 8, and cases cited; Rhode Island v. Massachusetts, 12 Pet. 657. The prevention and removal of clouds upon title are sub*212jects of the' general equity jurisdiction ; and the statute establishing the Rock Creek Park does not purport in the remotest degree to interfere with that or any other branch of equity. When the Supreme Court of the District of Columbia, whether as a court or as an appellate board of assessment, was given the authority referred to here “to hear and determine all matters connected with said assessment,” it certainly was not contemplated that one of those matters would be the power of Congress to pass that act itself. And while a court of limited jurisdiction, a board of commissioners, an executive officer, or a" private citizen, might decline to exercise powers conferred by a statute which is believed to be void, and would necessarily haye to pass upon the question of the validity of the authority sought tobe conferred in order to reáchthe conclusion, yet undoubtedly the attempt to confer such authority cannot in general deprive the courts of general jurisdiction of their right in cases within their cognizance to inquire into the validity of the attempt. The right of the citizens to have recourse to the courts of this country ought not to be construed to be taken away by indirection, where the protection of those courts is the most needed.
¶13We have virtually so held in the cases of the District of Columbia v. Prospect Hill Cemetery and others (5 App. D. C. 497), where one of the consolidated suits was a bill in equity to restrain the enforcement of an unconstitutional or invalid statute, and where we affirmed the decision of the court below awarding an injunction in the case. In the same case, we sustained without question the appellate jurisdiction of this court, which would have been ousted as well'as the jurisdiction of equity, if the Special jurisdiction there conferred on the Supreme Court .of the District of Columbia were of the character to exclude the exercise of the general jurisdiction ; for that also, like the present, was a case of special statutory authority. The case of Shoemaker v. United States, 147 U. S. 282, necessarily affirms the same doctrine for that was a case growing out of this *213very same statute; and the Supreme Court of the United States there exercised without question the right of appeal from a judgment of the Supreme Court of the District of Columbia rendered in proceedings instituted under the same special jurisdiction. We do not mean to hold that a special jurisdiction is not to be exercised specially in accordance with the statute; but that the special jurisdiction here conferred on the Supreme Court of the District of Columbia does not preclude recourse to equity in proper cases of equity cognizance and does not take away the appellate jurisdiction of this court. Ex parte Zellner, 9 Wall. 244.
¶14If we had any doubt about the jurisdiction of equity in this case, with the consequent right of appeal to this court, we would, be disposed to resolve the doubt in favor of the jurisdiction, in view of the fact that, under the decisions in the cases of Shoemaker v. United States and the District of Columbia v. Prospect Hill Cemetery, the same precise question that is now raised could be raised by almost identical pleadings under an application of the Park commissioners for a confirmation of their assessment. And we think that it is of no great consequence in which' way the question is presented, and that the case is one in which we should look rather to the substance than the form.
¶15We are of opinion that this case is one proper, for the cognizance of a court of equity.
¶162.. With reference to the merits of the case, counsel for the appellants. in their brief raise two questions, broad enough in their scope, and of very great importance: X, Whether Congress has power to impose taxes upon land in • the District of Columbia by way of assessment for special benefits accruing to such land by reason of the expenditure of public funds for works of public utility ; and, 2. Whether, if such power exists, the act of September 27, 1S90, providing for the acquisition of land for the Rock Creek Park and the levy of assessments upon other lands, specially benefited -by its establishment, is a valid exercise of the power. And the argument on behalf of the appellants is directed to *214show that both questions should be answered in the affirmative.
¶17The extent of the jurisdiction of the Congress of the United States over the District of Columbia must be regarded as quite well settled. The District of Columbia was established for the purposes of the Federal Union, and not for any purposes of its own; and Congress acts therein as the legislature of the Union, but with exclusive jurisdiction extending to all legitimate subjects of legislation. Cohens v. Virginia, 6 Wheat. 264; Loughborough v. Blake, 5 Wheat. 317; Willard v. Presbury, 14 Wall. 676; Mattingly v. District of Columbia, 97 U. S. 690. But that this exclusive jurisdiction is limited and restricted by the Federal Constitution and the amendments thereof, and by the fundamental principles of right and justice recognized by that Constitution, is equally beyond question. Story on the Constitution, sec. 1234; Callan v. Wilson, 127 U. S. 640. There is no place anywhere in our system of government, State or Federal, for the theory of legislative omnipotence’ claimed to appertain to the English Parliament, But except in so far as it is thus restricted by the fundamental law, the legislative authority of .Congress over the District of Columbia is supreme and unlimited.
¶18Among the ordinary and essential attributes of sovereignty and. subjects of legislation is the power of taxation, which, as Mr. Cooley says in his Treatise on Constitutional Law, ch. 4, pi 55, is “ unlimited in its range as to the kind of taxes that shall be laid, or the subjects upon which it shall be imposed.” And yet this great and vast power of taxation is rigidly limited in the one respect that it must be uniform and equal in its operation, must be levied for public not for private purposes, and must be laid according to-some definite and positive rule of apportionment. Taxes may be laid upon lands, upon personal property, upon occupations, upon special classes of property, or upon special occupations, or upon persons ; but within the scope of the selection the tax must be uniform. One man cannot be *215taxed more in proportion than another. These are well established principles of the law of taxation that require no citation of authorities to support them.
¶19It may be that this principle of uniformity is not secured for the District of Columbia, with regard to the power of exclusive legislation over it that is vested in Congress by the requirement of the Eighth Section of the First Article of the Constitution, that “ all duties, imposts, and excises shall be uniform throughout the United States for that may well be construed to refer to taxes levied by Congress over the whole territory of the Union. But it is abundantly secured by the provision in the Fifth Amendment to the Constitution that “no person shall be deprived of life, liberty or property without due process of law: nor shall private property be taken for public use without just compensation.” For private property would be taken for public use without any compensation, and due process of law would absolutely be wanting in any system of taxation that was not uniform in its operations — not necessarily uniform in its results or operating to do exact justice, but free from undue discrimination as to persons.
¶20Whether taxation by way of special assessment is free from the objection of want of uniformity is open to grave doubt. The practice of levying special assessments seems to be now very generally established throughout our country by legislative and municipal action, and to have received the sanction of courts and of text-writers, yet evidently not without some misgivings as to the correctness in principle of the theoiy upon which the practice is based. See Cooley on Taxation, pp. 416, 417. With all due respect to the public sentiment in favor of the theory of special assessments and to the great preponderance of judicial decision by which it has been sustained, we are disposed to think that a system, to which a large part of the municipal corruption that exists in our country can be traced, and which leads to a result so absurd as that evidenced in the act of Congress now under consideration, must be radically *216vicious and unjust. We think that it is vicious, because it is arbitrary; all things arbitrary in the administration of government are vicious. We think that it is unjust, because it compels the individual citizen in many cases, probably in most cases, to pay more than his just share of. the common burden for the public good.
¶21Special assessments are levied arbitrarily and without any rule having a fixed foundation in justice. They are usually authorized in connection with some unusual scheme of public improvement like this Rock Creek Park enterprise in the present instance. Generally they do not form part of any permanent or well-established scheme of taxation; and they vary in their scope and terms with every varying enterprise to the aid of which they are applied. Sometimes one-fourth, sometimes one-third, sometimes one-half, and sometimes even two-thirds or three-fourths of the cost of a public improvement is levied under the theory of special assessment upon adjoining owners supposed to be benefited specially by such public improvement. And if any part of the cost may so be assessed, the whole may be. Indeed, in the very case before us, it is sought to cast the whole and entire cost of the enterprise upon the adjoining owners; and the theory-is carried to its extreme extent, a conclusion that would make it ludicrous if it were not so grossly oppressive.
¶22But if these works, for which special assessments are sought to be levied, are public works, the public alone should pay for them. If they are not public works, the public authorities have no right to undertake them. We believe that there is no middle ground, of partnership in such work between the public and the individual citizen; and that compulsory payment therefor by the individual citizen is unjust, when perhaps he has not requested the improvement and may even have antagonized it. The system grew out of early legislation, m which, when the opening of streets or other public enterprises was somewhat in advance of the requirements or of the resources of a municipality or community, and private individuals, specially inter*217ested, and to whom the enterprise would be an immediate benefit, requested the work, compliance with their request was authorized upon their assumption of a share of the expense. But in those cases the special assessment was the result of a contract, and w'a's therefore never compulsory.
¶23We are aware that there is very great plausibility in the theory of special assessment. At first sight it seems to be exceedingly just and equitable that one whose property has* been enhanced in value by. its proximity to a public im-.' provement, should- contribute to the cost of that improvement in proportion to the amount of benefit received by his property. But the proposition is more plausible than sound. Apart from the incongruity of benefiting one without his consent and possibly against his will and then levying a contribution upon him for that in which he has had no voice, and assuming that the so-called benefits are not illusory and intangible, the fair and just contribution of the citizen is secured without arbitrary exaction by the increased assessment of his property for general taxation and the increased returns therefrom to the general fund. Moreover, it is not quite apparent, upon general principles of. justice, why, when a public improvement is located in a certain neighborhood, without inducement by adjoining owners for its location there, peremptory demand should then be made upon those owners to hand over to the public a sum of money equivalent to the supposed enhancement of their property in value by reason of tire location of the public improvement. A private individual, who improves a neighborhood by building therein,- could not with much grace support a demand upon his neighbors for contribution to the cost of his building, on the ground that their property has been enhanced in value by his action; and there does not seem to be any better reason for -the public to do so. Nor, when contrary conditions arise, is there any rule of law or equity that requires the public to compensate an adjoining owner, ■when his property has been depreciated in value by the location in his neighborhood of a jail, or a pest-house, or any *218other similar undesirable structure. The sovereign, or a municipality as the representative of the sovereign, should not shield itself in the one case behind the theory that the State can do no wrong, and yet claim in the other case that there is natural equity in its favor.
¶24But while we have deemed it not improper thus strongly to express our views upon the substantial merits of the theory of special assessment, it must be admitted, as. we have already stated, that the great preponderance of judicial authority is in favor of sustaining the validity of legislative action which imposes such assessments. In our own jurisdiction the Supreme Court of the United States, in the case of Mattingly v. District of Columbia, 97 U. S. 687, has sustained the .theory, upon the ground merely of the great current of judicial decision to that effect; and to that authority, of course, we must bow. It is not necessary for us in the present case to base our decision upon the hardship of special assessments, or upon the supposed unsoundness of the theory upon which they are sustained. The theory has its limitations and restrictions, as has the power of general taxation; and we think that it will be found, upon a closer analysis of the authorities, at all events of the best authorities upon the subject, that the theory has been applied only when some easement or appurtenance has been added to the lands of the person assessed, or when some advantage has been given to him which he did not possess before, such generally as the improvement of a street for access to his property, or the construction of a sewer for the drainage of his land, or some similar work which he could and should have done for himself, if it were not- that such work by a private individual for obvious reasons would be impracticable.
¶25The Rock Creek Park, authorized by the statute now before us, is nothing of that kind. It is something, as expressly declared in the act, “ perpetually dedicated and set apart as a public park or pleasure ground for the benefit and enjoyment of the people of the United States.” It is a public enterprise, therefore, for a purely public purpose, and *219for the general benefit of all the people of the Union; and assuming that, inasmuch as it is located in the District of Columbia, and is of special benefit to the District of Columbia, Congress can properly impose a special assessment on the District of Columbia to defray a part of its expense, it does not' follow that it can go farther and impose the whole cost or any part of it upon any individual or number of individuals in the neighborhood whom it pleases to select for the purpose of assessment Recognized territorial subdivisions, such as counties, townships, municipalities, may undoubtedly be specially assessed under the authority of the State for a share of the cost of works of public improvement located within their borders ; for the reason that such territorial organizations are only creatures of the State for governmental purposes and are wholly within the control of the State; and what we have heretofore said in reference to special assessments in general has no application to them. This much we understand to have been decided in the case of Mobile v. Kimball, 102 U. S. 691; and this also is the extent to which we understand the intimation to go of the Supreme Court of the United States in the case already cited of Shoemaker v. United States, 147 U. S. 282. Nor do we understand that any different principle is laid down by any of the decisions cited in the latter case. But individual citizens cannot thus be selected for assessment, nor can their property be constituted a special taxing district for the occasion.. Mr. Justice Cox, in his excellent opinion in this case, well said:
When it comes to assessing individuals for public im> provements, the question seems to be different. Suppose, for example, a court-house or a public monument or post-office should be erected in a town and the private property of individuals adjacent to it should be specially taxed for the supposed greater convenience which they enjoy of access to the court-house or postoffice, or the privilege of gazing upon the-public monument, it would at once be seen that great. injustice had been done. It does seem to me *220that this would be a system of taxation which would not conform to the spirit of our Constitution. It might as well have been held proper to assess the buildings opposite this court-house for the pleasure of gazing upon the Lincoln monument, if that monument had been erected by public authority.”
¶26In this we fully concur. We think that it fairly and justly expresses the law on the subject. The sixth section of the act of Congress of February 27, 1890, establishing the Rock Creek Park, so far as it can possibly be construed to have a meaning,- has for its sole object and purpose the imposition of a special assessment on the lands adjoining the park for the purpose of paying the cost and expense of the park. In fact, it seems to have been .contemplated that such special assessment might pay the whole cost and expense of the park, including even the compensation payable to the commissioners, and leave a surplus' to be. expended in the improvement of the grounds. More than that — the section- is capable of a construction that would make the enterprise a speculation of most extraordinary and remarkable profit to the United States ; for besides the fact that under it an assessment would be possible that would secure sufficient money to replace in the Treasury of the United States the whole amount of $1,200,000 that was expended in the acquisition of the land for the park, there is the provision that the District of Columbia as a municipality must in any event refund one-half the amount, or $600,000, to the Treasury. So that it would be quite feasible under the act for the United States to receive $1,800,000 by a levy ot forced contribution to reimburse them for their expenditure of $1,200,000. Such a result would be shocking to our sense of natural justice, to all our ideas of constitutional guaranty, and to our whole theory of governmental propriety. An enactment that necessarily leads to this conclusion we are compelled to regard as a violation of-the Constitution of the United States.
¶273. But proceeding one step farther, we find that not only *221is this section violative of the fundamental law of the land, but it is likewise so hopelessly inconsistent and meaningless that it is impossible to determine its sense with any certainty ; and consequently impossible to execute it with any propriety, even if it were not affected with the fatal taint of unconstitutionality. It is very evident that this section was passed without much, if any, consideration by Congress. It does not reflect the legislative mind or express the legislative intention, and it is-so hopelessly involved in palpable inconsistency and a maze of meaningless verbiage that it is impossible to apply to it any of the canons of construction that a court is authorized to apply in such cases. Counsel for the appellants virtually ask us so to reconstruct the phraseology of the enactment as to give it sense and meaning. Courts have gone very far, where the legislative intention is clear, to disregard words and terms that were evidently not contemplated to be in the statute, in some cases even converting negative phrases into positive phrases, and the reverse (Chapman v. State, 16 Tex. App, 78); but in all such cases the meaning intended by the legislature must be clear from the context. Not only is the meaning in the present case not clear: it is difficult, if not impossible to deduce any meaning from the language employed. We can add nothing to the excellent analysis of the section made by Mr. Justice Cox, in his opinion; which appears in the record in the case; and we can do no better than concur in that opinion and embody it in our own.
¶28One feature of that opinion we may emphasize. One clause of section 6 seems to authorize assessment by the commissioners for benefits accruing from the location and improvement of the park; another clause for benefits accruing from the location alone. It is conceded' that there has been absolutely no improvement whatever of the park thus far, and that the only change is in the transfer of title to the United'States. The only power to assess'is, therefore, in the clause which authorizes assessment for location, if it *222does, in fact, so authorize; and here again it is conceded that there has been no change whatever from previous conditions. Adjacent owners, then, are to be assessed .because the United States have taken title to a tract of land adjoining them, in order to lessen the burden of expense to the United States. To state the proposition is to demonstrate its gross absurdity.
¶29We think that the decree of the Supreme Court of the District of Columbia in the premises was right; and that decree must be affirmed with costs.
¶30For opinion of Mr. Justice Cox, see page 194- — Reporter.
¶31dissenting:
¶32I regret very much that there should be any dissent from the opinion of the majority of the court in this case. But I feel compelled to dissent from the opinion and conclusion of my brothers in respect to the two main propositions maintained by them in their opinion. . First, that there is jurisdiction in a court of equity to grant the relief prayed for in the original and supplemental bill, upon wdiich the decree below was founded ; and, second, that the express power given by the sixth section of the act of Congress of September 27, 1890, authorizing the assessment of real estate for special benefits accruing thereto, by reason of the establishment of a public park in the District of Columbia, is in violation of the Constitution of the United States, and therefore utterly void.
¶33I shall state the reasons of my dissent on these two propositions briefly, and shall, therefore, not attempt to recite the allegations of the bill. Suffice it to say, that the application for and the granting of the injunction were both before any assessment had been actually made upon the property of the complainants; and that, while there are many grounds alleged in the bill for the injunction, the principal ground for the relief prayed is, that of the supposed unconstitutionality of the sixth section of the act of Congress authorizing the establishment of the park.
¶34*223The defendants, United States officers and agents, constituted by the act a commission to lay off and acquire the land for the park, either by purchase or condemnation, with authority to make the special assessments upon the lands specially benefited by the improvement, answered certain parts of the original and supplemental bill of the complainants, and demurred to certain other parts; and for cause of demurrer, alleged that.the complainants have not in and by their original and supplemental bill, made or stated such a case as entitles them to any relief in a court of equity.
¶35On this state of the record the majority of this court hold, as I understand the opinion, affirming the decree of the court below, that a court of equity has jurisdiction to take cognizance of the case, and that the sixth section of the act of Congress involved is entirely unconstitutional and therefore void, and that, consequently, the complainants are entitled to a perpetual injunction against the exercise of any of the powers thereby attempted to be conferred by Congress.
¶36i. With respect to the first question presented, that of the jurisdiction of a court of equity to take cognizance of the case, I entirely dissent from the opinion of the majority of the court. Congress having by the act in question provided the mode of procedure, and conferred, by express terms, jurisdiction upon the Supreme Court of the District, “ to hear and determine all matters connected with said assessment ; and to revise, correct, amend, and confirm said assessment, in whole or in part, or order a new assessment in whole or in part, with or without further notice, or on such notice as it shall prescribeand declared that “ the orders of the court shall be conclusive evidence of the regularity of all previous proceedings necessary to the validity thereof, and of all matters recited in said orders,” in my opinion, a court of equity has no power to review and control the action of the Supreme Court of the District, in the exercise of its powers and jurisdiction under the statute. That jurisdiction is exclusive, subject only to the right of appeal to an appellate jurisdiction upon questions of con*224stitutional rights actually involved in the proceeding. To give to a court of equity jurisdiction, in the absence of express statute, there must be presented a case where the principles of law, by which the ordinary courts are guided, give right, but the powers of those courts aré not sufficient to afford a complete remedy, or their modes of proceeding are inadequate to attain full and complete justice; or where the courts of ordinary jurisdiction are made instruments of injustice; .or where the principles of law by which the ordinary courts are governed give no rights, but • upon the principles of universal justice, the interference of a court of equity is necessary to prevent a wrong, the positive law being silent. In neither of these categories is the present case embraced. There is ample remedy provided by the statute; and where the legislature has given jurisdiction by statute to a designated court, for taking and conducting proceedings under the statute, and- especially where it has made the decision of that court final, no equity can be founded on the allegation that such court is not properly competent to decide questions that may arise within its jurisdiction. In such case, a court of equity does not become a court of review, nor can it be made subsidiary to the tribunal created or clothed with power by the legislature for settling the rights of parties, upon the mere ground that that tribunal has miscarried, or .may miscarry, in the settlement of those rights. Canal Co. v. Tribell, 7 Beav. 19, 28; Bateman v. Boynton, L. R. 1 Ch. App. 360, 368. The Supreme Court of the District was given power and jurisdiction, by the .terms of the statute, after due notice given, "to hear and determine all matters connected with said assessment and the mode of proceeding prescribed by the statute, is due process of law. The Supreme Court of the District was and is competent to decide every question connected with the assessment, that could arise or be presented in the course of the proceeding, including the question of the constitutionality of the act itself. In the event'of holding the act, or any’ part of it, unconstitutional, or the re*225fusal so to hold it, upon presentation of such question to the court by exception to the report of the commis.sioners, an appeal would lie to this court, as a writ of error did lie to the Supreme Court of the United States before this court was established. Shoemaker v. United States, 147 U. S. 282. And even an appellate court, much less a court of equity on a collateral application, will not interfere with the report of commissioners, to correct errors of procedure, or errors' of judgment in arriving at the amount of assessment. Mills on Eminent Domain, 246; Shoemaker v. United States, supra. This is well illustrated by the much cited case of Mooers v. Smedley, 6 John. Ch. 28. In that case the supervisors of a town, under an act of the legislature, and pursuant to the vote of the town, allowed bounties for the destruction of wolves, the amount of which was inserted in the annual tax list, to be levied and collected of the owners of land. On an application for an injunction, to restrain the collection of the sums so allowed for bounties, the injunction was denied. And in denying the injunction, Chancellor Kent remarked: " I cannot find, by any statute, or precedent, or practice, that it belongs to the jurisdiction of chancery, as a court of equity, to review or control the determination of the supervisors, in their examination and allowance of accounts as chargeable against their county, or any of it? towns, and in causing the money so allowed to be raised and levied. There was no allegation of fraud or corruption in the case. The most that could be said, was, that they made an erroneous determination.” That case has been cited and approved by the Supreme Court of the United States in the case of Hannewinkle v. Georgetown, 15 Wall. 547. In the present case, as irt the case of Mooers v. Smedley, there is no allegation or pretence that there is any fraud or corruption in the case. Here, there was a competent court provided to direct and supervise the.proceedings of the commissioners.
¶37The effort to introduce an element that would give jurisdiction to the court, by alleging that the threat of assess*226ment for special benefits would produce a cloud upon the title of the property of the ■ complainants, because, if consummated, such assessment would create a lien upoh the property, will not justify a court of equity in interposing, and thereby become a court of review upon the proceedings authorized by the statute. Such allegation is easily made, and it could as well be made in every case of proceeding at law, where the judgment would create a lien upon the property of the debtor, as in the present case. There must be something more than the mere fact that the property may be subject to a lien, as the finál result of the pending proceeding, in order to confer jurisdiction upon a court of equity to arrest such proceeding by injunction. 'In this case, according to the theory and assumption of the bill, the attempted assessment for special benefits is unconstitutional and void, because the act of Congress was passed without constitutional warrant, and is therefore void upon its face. If this be true, according to well-established principle, there is no such cloud upon the title as will justify the interference of a court of equity; the statute showing upon its face that it is without force or authority to charge the estate. Dows v. The City of Chicago, 11 Wall. 109; Hannewinkle v. Georgetown, 15 Wall. 547.
¶38Courts of equity are not constituted for the purpose of arresting proceedings, and assuming to themselves the right of disposing of cases, that are properly depending in the ordinary courts of law. It is only upon special and particular circumstances, appealing to the conscience of the chancellor, that a court of equity is justified in interposing for the relief of the party complaining. A .court of equity is not constituted a court of review on constitutional questions that may be decided by tribunals inferior to the Supreme Court of the United States ; nor is such court possessed of exclusive, nor even of concurrent, jurisdiction in respect to such questions ; and hence there is no authority or reasonable ground for coming to a court of equity in a-case like the present. In every case, circumstances should be stated *227that show that in the particular case there is an equity that cannot be availed of by the party complaining, in the proceedings sought to be restrained. There can be no reason or propriety in appealing to a court of equity to restrain proceedings that are being regularly conducted in other courts, competent to construe the statutes under which they act, and to decide every question that may arise in the course of the proceeding. To allow litigations to be thus diverted, tends to the multiplication of litigation, and the production of unnecessary delay and expense, to say nothing of the unnecessary vexation to parties. I am of opinion, therefore, that there is no jurisdiction in equity to maintain the. bill in -this case.
¶392. But, assuming the existence of jurisdiction, and that the question was properly before this court for decision, in such case, I should have no difficulty whatever in holding that the sixth section of the act of Congress of September 27, 1890, 26 Stat. 492, ch. 1007, is constitutional and valid. Looking to the large and unrestricted legislative power of Congress over this District, under the Constitution, if the power to authorize assessments for special benefits, by reason of improvements, exists anywhere, it would seem certainly to exist here. The sixth section, declared unconstitutional by the opinion of the majority of the court, forms a vital part of the act, and in fact constitutes the basis of the plan and scheme of the park. Without the provi sion contained in the sixth section of the act, to supply the means of indemnity and reimbursement, it can hardly be supposed that Congress would have passed the act, and charged the entire cost and expense of the improvement to the Treasury of the United States, and to the District of Columbia. It was in view of what was deemed, a well-settled principle, that of legislative power to authorize assessments for special benefits, that Congress provided by the sixth section of the act, that the commissioners should assess, by way of indemnity and reimbursement, “such proportion of the cost and expenses upon the lands in the *228District of Columbia specially benefited by reason of the location and improvement of said park, as nearly as may be, in proportion to the benefits resulting to such real estate.” The constitutional power to impose such assessments for special benefits, was supposed to be too well established to •be made a matter of serious question. It'had.been so expressly decided by the Supreme Court of the United States, in cases arising in this District. Hannewinkle v. Georgetown, 15 Wall. 547; Mattingly v. District of Columbia, 97 U. S. 687. A.nd in a case arising under the very statute now under consideration, the question of the constitutionality of the sixth section of the act was pointedly made and expressly decided in affirmance of the validity of the section, and of the entire act. Indeed, to strike from the statute the sixth section, as being unconstitutional or otherwise void, is simply to disembowel the act, and destroy the means designed for the ultimate payment of the cost and expenses of the improvement, and impose the whole bur-then upon the United States Treasuiy and the District of Columbia. This is a very grave consequence of declaring the sixth section of the act unconstitutional, or otherwise inoperative, and it should only be so declared upon the plainest and most unmistakable ground. In my judgment, with all due deference to the opinion of my brothers, the sixth section of'the act is not only constitutional upon general'prindpl'es of legislative power, but it has been so expressly declared by the Supreme Court of the United States, in the case just referred to, of Shoemaker v. United States, 147 U. S. 302.
¶40In that case, the court, in- considering the. several questions that involved the constitutionality of the entire act, said: “A further objection is made to the validity of the act, by reason of the sixth section, which provides for the assessment of benefits resulting from ‘the location and improvement of said park,’ upon lands so especially benefited.
¶41“ The cases heretofore cited to show that the erection of parks in cities is a public use, in a constitutional sense, *229were, most of them, cases in which it was likewise held that it is competent for the legislature, in providing for the cost of such parks, to assess a proportionate part of the cost upon property specially benefited ; and we need not repeat the citations.
¶42“ No special request, on the subject of the legal- effect of the provision in respect to special benefits, seems to have been made to the court below, and there is no specific assignment of error as to it. Nor does it appear that any person having property actually assessed for special benefits is a- party as plaintiff in error. We are therefore relieved from any extended consideration of this feature of the act.”
¶43And, in .the conclusion of the opinion, the court say, “ Our conclusion is that we find, in the legislation creating the park and in the proceedings under it, no infringment of the Constitution or of the legal rights of the plaintiffs in error, and the judgment of the court below is accordingly affirmed.”
¶44This broad declaration as to the validity of the act would hardly have been made by the court, if one of the principal parts of the statute, and which had been urged as being unconstitutional, and therefore affecting the validity of the entire act, had appeared to the court as being subject to the objection taken to it. I see nothing in the sixth section of the act which requires from the court the declaration that the section is unconstitutional, or otherwise void, or. inoperative, either in whole or in part. And being of this opinion, I must dissent from the opinion of the majority of the court; and, according to my opinion, the bill filed in this case should have been dismissed.
