after stating the case, delivered the opinion of the court.
It is familiar law that a State has no power to tax the property of the United States within its limits. This exemption of the.ir property from state taxation — and by state taxation we mean any taxation by authority of the State, whether it be strictly for state purposes or for mere local and special objects — is founded upon that principle which inheres in every independent government, that it must be free from any such interference of another government as may tend to destroy its powers or impair their efficiency. If the property of the United States could be subjected to taxation by the State, the object and extent of the taxation would be subject to the State’s discretion. It might extend to buildings and other property essential to the discharge of the ordinary business of the national government, and in the enforcement of the tax those buildings might.be táken from the possession and use of the United States. The Constitution vests-■ in Congress the power to
“
dispose of and make all needful rules and regulations- respecting the territory'or other property belonging, to the United States.” And this implies an exclusion of all .other authority over the property which could interfere with this right or obstruct its exercise.
Van Brocklin
v.
State of Tennessee,
This doctrine of exemption from taxation of the property of the United States, so far as lands are concerned, is in express *505 terms, affirmed in the constitution of Wisconsin, which ordains that the State “ shall never interfere with the primary disposition of the soil within the same by the United States, nor with any regulations Congress may find necessary.for securing the title in such soil to bona fide purchasers thereof; and no tax shall be imposed on land the property of the United States.” Constitution of 1848, Art. II, sec. 2.
It follows that all the public domain of the United States within 'the State of Wisconsin was in 1883 exempt from state taxation. Usually the possession of the legal title by the government determines both the fact and the right of ownership. There is, however, an exception to this doctrine with respect to the public domain, which is as well settled as the doctrine itself, and that is, that where Congress has prescribed the conditions upon which portions of that domain may be alienated, and provided that .upon the performance of the conditions a patent of the United States shall issue to- the donee or purchaser, and all such conditions are complied with, the land' alienated being distinctly defined, it only remaining for the government to issue its patent, and until such issue holding the legal title in trust for him, who in the meantime is not excluded from the use of the property — in other words, when the government has ceased to hold any such right or interest in the property as to justify it in withholding a patent from the donee or purchaser, and it does not exclude him from the use of the property — then the donee or purchaser will be treated as the beneficial owner of the land, and the same be held subject to taxation as his property. This exception to the general doctrine is founded upon the principle that he who has the right to property, and is not excluded from its enjoyment, shall not be permitted to use the legal title of the government to avoid his just share of state taxation.

In the light of these decisions, it will b¿ necessary, in’order to determine the liability of the property held by the plaintiff to taxation in 1883, to consider the nature and extent of its interest in the property at that time acquired under the grant of Congress of May, 1864, and by its subsequent construction of the road.
Numerous grants of land were made by Congress between 1860 and 1880 to aid in the construction of railroads; some directly to incorporated companies, others to different States, the lands to be by them transferred to companies by whom the construction of the roads might be undertaken. The different acts making these grants were similar in their general provisions, and so many of them .have been, at different times, before this court for consideration that little can be said of their purport and meaning, the title they transfer, and the conditions upon which the lands could be used and disposed of, which has not already and repeatedly been said in its decisions. Each grant gave a specified quantity of lands, designated by sections along the route of the proposed road, with the exception of such as might, when the line of the road should be definitely fixed,’ have been disposed- of or reserved by the government, or to which a preemption or homestead right might then have attached. .• Eor these ■ ex- ■ cepted sections, which otherwise would have been taken from those designated along the line of the road, other lands beyond those sections within a specified distance were allowed to. be selected. The title conferred was a present one, so as to insure the donation .for the construction of the road proposed against any revocation by Congress, except for non-performance of the work within the period designated, accompanied, however, with such restrictions upon the use and disposal of the lands aiy to prevent their diversion from the purposes of the grant. It was the practice’of the Land Department, as shown by the evidence in this record, up to the decision of
Leavenworth, Lawrence & Galveston Railroad Co.
v.
United States,
in April, 1876, 92 U. S.
*508
733, to allow deficiencies in the quantity of land intended to be granted, arising from sales or other disposition made before the daté of the grant, as well as those made subsequently, and those arising from the attachment of preemption or homestead rights, to be supplied from lands lying beyond the 'original sections, within what were termed the indemnity limits. This practice was held in
Winona
&
St. Peter Railroad Co.
v.
Barney
to have been correct.
After the decision of the court in the Leavenworth case the Land-Department changed its practice and refused to allow the deficiencies, arising from sales or other disposition made, or from the attachment of preemption or homestead rights before the date of the act, to be made up from selections within the indemnity limits. But that decision did not warrant the change.' The question in that casq was not, for what deficien *509 cies indemnity could be had, but what lands could be taken for deficiencies which existed. If what was then said indicated that deficiencies which could be supplied were limited to such as might arise after the passage of the act, it was a mere dictum not essential to the decision, and therefore not authoritative and binding. The refusal of the Land Department, therefore, to allow the. deficiencies arising in the sections within the place limits in this case to be supplied by selections from the indemnity lands, and to issue patents of the United States for them, was erroneous.
The question now arises as to how far this refusal affected the legal or equitable title of the company to the lands taxed in 1883, for which it only obtained a patent in 1881. The lands' taxed amounted to eleven parcels of forty acres each lying within the original sections named in the grant, that is, within the ten miles limit from the line of the road, and the remainder were. within the indemnity limits. Neither were allowed, because, by excluding the deficiencies arising before the date of the grant from • indemnity, the whole amount of the lands granted had already been- patented. So far as the eleven parcels of forty acres each are concerned, the right of the plaintiff to them and. to a patent for them had as early as 1877 become complete under the terms of the granting act. The line of the railroad had been definitely fixed on the 7th of October, 1869 ; and the three twenty-mile sections, -numbers five, six, and seven, were all completed in June, 1877, and supplied with tlje buildings and appurtenances specified in the' act to entitle the company to patents for them from the United States. The title conferred by the grant was necessarily an imperfect one, because, until the lands were identified by the definite location of the road, it could not be known what specific lands would be embraced fn the sections named; The grant was, therefore, until such location, a float. But when the route of the road was definitely fixed, the sections granted became susceptible of identification; and the title attached to them and took effect as of the date of the grant, so as to cut off all intervening claims.

■ There are many instances in the reports where such effect as is here stated has been given to patents authorized or directed tó -be issued to parties, notwithstanding they had previously received a legislative grant of the premises, or their title had been already confirmed. In
Langdeau
v.
Hanes,
But as to the remainder, of the lands taxed, which fell within the indemnity limits, the case is different. For such lands no title could pass to the company not. only until the selections were made by the agents of the State appointed by the governor, but' until such selections were approved by the Secretary-of the Interior. The agent of the State made the selections, and they had been properly authenticated- and forwarded to the Secretary of the Interior. But that officer never approved of them. Nor can such approval be inferred from his not formally rejecting them. He refused, as already stated, to issue to the company any patents for any more lands, insisting that it had already received over 10,000 acres too much, and he directed the Commissioner of the, General Land Office to require the company to restore this excess to the government. The approval of the Secretary was essential to the efficacy of the selections, and to give to the company any title to the lands selected. His action in that matter was not ministerial but judicial.- He was required to determine, in the first place, whether there were any deficiencies in the land granted to the company which were to be supplied from indemnity lands\; and, in the second place, whether the particular indemnity lands selected could be properly taken for those deficiencies.' In order to reach a proper conclusion on these two questions he had also to inquire and determine whether any lands in the place limits had been previqusly disposed of by the government, or whether any preemption or homestead rights had attached before the line- of the road was definitely fixed. There could be no indemnity unless a loss was established. And in determining whether a. particular selection could be
*512
taken as indemnity for the losses sustained, he was obliged to inquire into the condition of those indemnity lands, and determine whether or not any portion of them had been appropriated for any other purpose, and if so, what portion had been thus appropriated, and what portion still remained. This action of the Secretary was required, not merely as- supervisory of the action of the agent of the State, but for the protection of the United States against an improper appropriation •of their lands. Until the selections were approved there were no selections in fact, only preliminary proceedings taken for that purpose ; and the indemnity lands remained unaffected in their title. Until then, the lands which might be taken as indemnity were incapable of identification; the proposed selections remained the property of the United States. The government was, indeed, under a promise to give the company indemnity lands in lieu of what might be lost by the causes mentioned. But such promise passed no title, and, until it -was executed, created no legal interest which could be enforced in the courts. The doctrine, that until selection made no title vests in any indemnity lands, has been recognized in several decisions of this court. Thus in

The same view has been held by different Attorneys General of the United States, in their official communications to heads of the departments, where selections of the public lands have been granted, subject to the approval of the Secretary of the Interior, Cape Mendocino Lighthouse Site, 14 Opinions Attys. Gen. 50, Portage Land Grant, Ib. 645, and such has been the consistent practise óf the Land Department. The uniform language is, that no title to indemnity lands becomes vested in any company or in the State until the selections are made: *514 and they are not considered as made until they have been approved, as'provided by statute, by the Secretary of the Interior.
It follows from these views that the indemnity lands described in the complaint were not subject to taxation as the property of the railroad company in 1883. The judgment of the Supreme Court of Wisconsin must, therefore, be
Reversed, and the cause remanded with directions to enter a decree perpetually enjoining the collection of the taxes , levied in the year 1883 upon the indemnity lands, and dismissing the complaint as to the eleven parcels of forty acres each j a/nd it is so ordered.
