delivered the opinion of the Court.
The State of Florida seeks leave to file a bill of complaint against the defendants, citizens of other states, to enjoin thеm from attempting to collect in Florida inheritance taxes imposed by § 301 of the Revenue Act of 1926, c. 27, 44 Stat. 9, 69-70.. A rule upon the defеndants to show cause why such leave should not be granted was issued and answered.
The complaint alleges that under the constitution of Florida no tax on inheritances can be levied by the state or under its authority; that by § 301 of the act referred to certain grаduated taxes are imposed on the estates of decedents subject to the following provision:
“ The tax imposed by thisi seсtion shall be credited with the amount of any estate, inheritance, legacy, or succession taxes actually paid to any State or Territory or the District of Columbia, in respect of any property included in the gross estate. The credit allowed by this subdivisiоn shall not exceed 80 per centum of the tax imposed by this section, and shall include only such taxes as were actually paid and credit therefor claimed within three years after the filing of the return required by section 304.”
It is further alleged that the defendants arе. officers of the United States and are seeking to enforce the provisions óf § 301; that citizens of Florida have died since the act was passed, leaving estates' subject to taxation under the terms of that section; that defendants have required and are requiring the legal representatives of such decedents to make returns under that section, and unless such action is restrained, it will rеsult in the withdrawal from Florida of several million dollars per annum and thus diminish the revenues of the state derived *16 largely from taxation of рroperty therein; that the state is directly interested in the matter because it raises by taxation a sufficient amount of revenuе to pay the expenses of the state government otherwise than by imposing inheritance taxes or taxes on incomes; and that the provisions of the said section, constitute an invasion of the sovereign rights of the state and a direct effort on the part of Congress to coerce the state into imposing an inheritance tax and to penalize it and its property and сitizens for the failure to do so. It is further alleged that the state is directly interested in preventing the unlawful discrimination against its citizens which is effected by § 301 and in protecting them against the risk of prosecution for failure to comply with the enforcement provisions оf the act; that the several states, except Florida, Alabama, and Nevada, levy inheritance taxes, but by reason of thе provisions of its constitution Florida cannot place. its citizens on an equality with those of the other states in respect of the fax in question, and [therefore] the tax N not uniform throughout the United States as required by § 8 of Article I of the federal Constitution.
The allegations of the bill suggest two possible grounds upon which the asserted right of complainant to invoke the jurisdiction of this court may be suрported: (a) that the state is directly injured because the imposition of the federal tax, in'the absence of a state, tаx which may be credited, will cause the withdrawal of property from the state with the consequent loss to the state of subjects оf taxation; and (b) that the citizens of the state are injured in such a way that the state may sue in their behalf as parens patriae. ■ Neither ground is tenable.
While judicial relief sometimes may be granted to a gwasi-sovereign .state under circumstances which . wTouid not justify relief if the suit were between private parties,

v.
Tennessee Copper Co.,
The act assailed was passed by Congress in pursuance of its power to lay and collect taxes, and, following the decision of this court in respect of the precеding act of-1916,
New York Trust Co.
v.
Eisner,
The contention that the federal tax is not uniform becаuse other states impose inheritance taxes while Florida does not, is without merit. Congress cannot accommodate its legislation to .the conflicting or dissimilar laws of the several states nor control the diverse conditions to be found in the various states which necessarily work unlike results from the enforcement of the same tax. All that the Constitution (Art. I, § 8, cl. 1) requires is that the law shall be uniform, in the sense that by its provisions the rule of liability shall be the same in all parts of the United States.
The claim of immediate injury to the state rests uрon the .allegation that the act will have the “result of inducing potential tax-payers to withdraw property from the state,
*18
thereby diminishing the subjects upon which the state power of taxation may operate. The averment to that effect, howevеr, affords no- basis for relief, because, not only is the state’s right of taxation subordinate to that of the general government, b.ut the аnticipated result is purely speculative, and, at most, only remote and indirect;
Minnesota
v.
Northern Securities Co.,
Nor can the suit! be maintained by the state because of any injury to its citizens. They are also citizens- of the United States and subject to its laws. In respect of their relations with the federal government “ it is the United .Stаtes, and not the State, which represents them as parens patriae, when such representation becomes appropriate; and to the former, and not to the latter, they must look for such protective measures as flow from that status.” Massachusetts v. Mellon, supra, pp. 485-486.
It follows that leave to file the bill of complaint must' be denied.
'Rule discharged and leave denied.
