OPINION

CLAY, Circuit Judge.

Defendants Naftaly, et al., appeal the June 1, 2005 order of the United States District Court for the Western District of Michigan granting Plaintiff Keweenaw Bay Indian Community's motion for summary judgment, entering the declaratory judgment that the Michigan General Property Tax Act ("Act"), Mich. Comp. Laws § 211.1 et seq., was not valid as applied to real property held in fee simple by Plaintiff or its members within the exterior boundaries of the L'Anse Indian Reservation, and enjoining Defendants from enforcing the Act against said real property. For the following reasons, we AFFIRM the order of the district court.

I. BACKGROUND

A. PROCEDURAL HISTORY

On August 13, 2003, Plaintiff filed a complaint in the United States District Court for the Western District of Michigan seeking declaratory and injunctive relief against Defendants. The suit was in response to Defendants' attempts to assess, collect, and enforce ad valorem taxes under the Act against real property within the L'Anse reservation held by Plaintiff or its members in fee simple.

On December 12, 2003, Defendants filed a motion to dismiss under Federal Rules of Procedure 12(b)(1) and 12(b)(6). On September 27, 2004, the district court denied the motion.

On October 26, 2004, Defendants filed a motion to dismiss under Rule 12(b)(6) and a motion for summary judgment under Rule 56. On December 17, 2004, Plaintiff filed a motion for summary judgment under Rule 56 on Counts I and II of its complaint. Count I alleged that Plaintiff was entitled to declaratory and injunctive relief because Congress had not clearly authorized state taxation of the real property at issue. Count II alleged that Plaintiff was entitled to declaratory and injunctive relief because application of the Act would violate the terms of the 1854 Treaty. On June 1, 2005, the district court denied Defendants' motion for summary judgment, granted Plaintiff's motion for summary judgment, entered a declaratory judgment that the Act was not valid as applied to the real property at issue, and enjoined Defendants from enforcing the Act against said real property. On June 28, 2005, Defendants timely filed a notice of appeal.

2. The History Preceding the 1854 Treaty

The following historical account was found by a district court in a case unrelated to the case before this Court, Keweenaw Bay Indian Community v. State of Michigan, 784 F.Supp. 418 (W.D.Mich. 1991):

The Keweenaw Bay is located on the southern shore of Lake Superior in Michigan's Upper Peninsula. From the earliest records there existed a band of Lake Superior Chippewa Indians near the mouth of the Bay, on an east-west transportation corridor used by the Indians and later by fur traders. The Indians subsisted before the coming of European society, consistent with their traditional lifestyle, which included annual rounds of hunting and trapping in the Winter and fishing in the Spring, Summer and Fall. The Lake Superior Chippewas' lifestyle was first impacted by contact with the French, followed by the English and finally by the Americans. Euro-American contacts exposed the Chippewa, inter alia, to Christianity, a new kind of market economy, greed and avarice for their lands, intoxicants, disease, and a new style of dress and abode. These contacts, of course, did not supplant their culture.

. . . .

The 1832 expedition of Henry Schoolcraft, followed by Douglas Houghton's famous exploration of the western Upper Peninsula, outlined the immense mineral reserves of the Western Range and the Keweenaw Peninsula, which were all held at that time by the Indians, pursuant to their unextinguished aboriginal title. Not surprisingly, these rich mineral deposits evoked considerable interest from land speculators, miners, and the federal government.

The United States Congress appropriated money on March 3, 1841, to defray expenses of entering into a treaty with the Chippewa for the extinguishment of their title within the State of Michigan where the mineral deposits were found. The Treaty with the Chippewa, 7 Stat. 591, was subsequently negotiated on October 4, 1842, under which the Indians conveyed to the United States their aboriginal title to the entire western half of Michigan's Upper Peninsula, including the Keweenaw Bay area, and to all of northern Wisconsin. Although Article III of the treaty provided for the eventual removal of the Indians to an area to the west occupied by the Mississippi Chippewa, it was thought that such removal would not take place for a considerable time in the future. Ex. P-7. In Article II, the Indians stipulated for the right to hunt in the ceded territory, together "with the other usual privileges of occupancy, until required to remove by the President of the United States. . . ." Article VI provided that the Indians would be subject to removal from the mineral district at the pleasure of the President. It was contemplated that this limited removal from the mineral areas, if it occurred, would not move the Indians out of the remainder of their cession area. Article IV provided for the payment of annuities and the furnishing of goods and services to the Indians, including blacksmiths and carpenter shops, and schools. Notwithstanding the cession of title, the United States' laws with respect to trade and intercourse with non-Indians were to remain in effect in the ceded territory.

The events at Keweenaw Bay following the signing of the 1842 Treaty were significant. In accord with the treaty, farmers and blacksmiths were provided to the L'Anse band, along with funding to the mission boards in order to provide schools for the Indians. Although the treaty did not provide for land reservations, by all accounts the Indians were advised, and they so understood, that their lifestyle would be essentially unchanged after the treaty because the government only sought their minerals. Notwithstanding these assurances, the Indians, who did not want to remove, were very apprehensive about that potential. Of course, the threat of removal at that time seemed remote because the Indians were not living within the two important mineral districts in the area. The Indians' comfort was short-lived, however, due to the commencement of land surveying in 1845, which meant that legal descriptions could be made and land could be sold. To the Indians, land sales meant that their removal was likely and imminent.

On February 6, 1850, the President issued a removal order, pursuant to the 1842 Treaty. I Tr. 159. However, that order was subsequently withdrawn in August, 1851, and the Indians were never actually required to remove. II Tr. 164. Nevertheless, according to Henry C. Gilbert, the Michigan Indian agent who negotiated the subsequent 1854 treaty, removal was "the great terror of their [the Indians'] lives and I hazard nothing in saying they will sooner submit to extermination than comply with it." Ex. P-25; II Tr. 166.

The survey of the Upper Peninsula area around Keweenaw Bay was completed in 1848. Some land purchases began to occur on both sides of the Bay at about that time. Numerous urgent letters and petitions from Indians and their representatives to Indian agents and the President evidenced concern about removal and revealed a desire to purchase land around the Bay by and for the benefit of the Indians. . . . Many Indians in the Keweenaw Bay area adopted American-style (or non-Indian) names, clothing, houses, and other customs. Some swore allegiance to the United States before a magistrate. These accommodations to American culture were often intended to demonstrate the Indians' advanced degree of "civilization". It was hoped by some that such accommodations would convince the government to grant them citizenship and permit them to remain in their homes rather than force them to remove to the west. Ex. D-71; VI Tr. 792; VII Tr. 906-907. A consistent Indian theme throughout the period of removal and prior to the 1854 Treaty was an ardent desire for permanent homes for the Indians in their present locations.

. . . .

The evidence indicates that in the 1840's, the federal government's policy towards Indians, known as "removal," was being abandoned. Removal was characterized by the movement of tribes from the eastern portion of the United States to lands to the west, out of the path of western settlement by non-Indians. The removal policy became antiquated as the settlement patterns of non-Indians moved inexorably westward. It became clear in the 1840's that there was rapidly becoming no place to move the Indians. II Tr. 184-5. The benevolent rationale for the removal was to isolate the Indians from the adverse impacts resulting from their contacts with non-Indian society. Of course, the primary motivation was to free Indian lands from their claims to them so the lands could be settled by non-Indians.

This same rationale underlay the creation of the reservation system, which replaced the removal policy. II Tr. 186. The separatism that was hoped for could no longer be achieved through removal. However, Commissioner George W. Manypenny believed that the civilization policy could be achieved through the reservation system. Thus, he believed that if the Indians were temporarily isolated on discrete parcels, away from the deleterious influence of non-Indians, they could gradually become assimilated or "civilized" and eventually could be incorporated completely into non-Indian society. VII Tr. 1022. The reservation concept as a "way-station" was a necessary step, then, in the civilization process. VII Tr. 967.

. . . The new policy of the government was to provide "permanent homes" on the reservations that were set aside for the Indians and upon which trespass by non-Indians would not be tolerated. Additionally, there were three evils attendant to the government's policy in the past, which Manypenny sought to avoid in the future: first, the payment to the Indians of excessive annuities, which promoted profligacy and the consumption of intoxicants; second, excessive quantities of land held in common; and third, continued changes in location in advance of the western movement of settlers. The 1854 Treaty, as well as others negotiated during this period, were intended to address these articulated evils.

Correspondence from Commissioner Manypenny to the Indian agents about to undertake treaty negotiations with the Lake Superior Chippewa in the early 1850's is critical to an understanding of the government's intentions. One of the four letters of instruction from Commissioner Manypenny to Henry C. Gilbert provides:

I send herewith a copy of the instructions of the Secretary of War of the date of 4th June of 1847 when a former commissioner attempted to treat with these indians but failed. According to the estimates of this office, the Chippewa own about 10,743,000 acres of land, the greater part of which is of no value to them, and never will be. Some portions of it will be valueless to the white population.

Nevertheless, the condition of affairs with the Chippewas is such that it is the duty of the Government to offer them an opportunity to dispose of their tenure to their Country, and in lieu thereof, to give them a small tract as a permanent home, with such means of support mental moral improvement as may be of great advantage to them.

Id. at 420-23.

3. The 1854 Treaty

On September 30, 1854, the President of the United States and the Chippewa Indians of Lake Superior and Mississippi entered into a treaty ("1854 Treaty"). Treaty with the Chippewa, September 30, 1854, 10 Stat. 1109. Under the 1854 Treaty, the Chippewa Indians ceded to the United States a substantial amount of land in eastern Minnesota. In exchange, the United States set aside permanent reservations for the various bands of Lake Superior and Mississippi Chippewa. The United States also provided annuities, goods, and services in consideration of the cessation.

Article 3 of the 1854 Treaty outlined certain powers the President maintained with respect to the reservation lands:

The United States will define the boundaries of the reserved tracts, whenever it may be necessary, by actual survey, and the President may, from time to time, at his discretion, cause the whole to be surveyed, and may assign to each head of a family or single person over twenty-one years of age, eighty acres of land for his or their separate use; and he may, at his discretion, as fast as the occupants become capable of transacting their own affairs, issue patents therefor to such occupants, with such restrictions of the power of alienation as he may see fit to impose. And he may also, at his discretion, make rules and regulations, respecting the disposition of the lands in case of the death of the head of a family, or single person occupying the same, or in case of its abandonment by them. And he may also assign other lands in exchange for mineral lands, if any such are found in the tracts herein set apart. And he may also make such changes in the boundaries of such reserved tracts or otherwise, as shall be necessary to prevent interference with any vested rights. All necessary roads, highways, and railroads, the lines of which may run through any of the reserved tracts, shall have the right of way through the same, compensation being made therefor as in other cases.

Importantly for the instant case, the President had the power to assign land to individual Chippewa Indians, and he also had the power to place restrictions on these allotments, as well as the power to remove such restrictions. One such restriction would be a restriction on alienation.

Article 10 allowed missionaries, teachers, and other non-Chippewa Indians who resided in the ceded territory or the reservations to remain on their occupied land at a minimum price.

Article 11 listed certain restrictions placed upon the United States:

All annuity payments to the Chippewas of Lake Superior, shall hereafter be made at L'Anse, La Pointe, Grand Portage, and on the St. Louis River; and the Indians shall not be required to remove from the homes hereby set apart for them. And such of them as reside in the territory hereby ceded, shall have the right to hunt and fish therein, until otherwise ordered by the President.

The 1854 Treaty was ratified on January 10, 1855. Subsequently, the President periodically assigned parcels of the reservation to individual Chippewa Indians pursuant to his power under Article 3 of the treaty. The real property in dispute in the instant case are those parcels allocated under Article 3 and those parcels allocated under Article 10 that are now in the possession of Plaintiff or its members.

4. Tax Treatment of Real Property Within the Reservation

After the 1854 Treaty, none of the lands within the reservation held by Plaintiff's predecessor tribes or its members in fee was subject to the Act and its ad valorem real property tax. In 1982, the Michigan Tax Tribunal explicitly held that lands held by Plaintiff and its members were not subject to the Act; however, the tribunal held that lands within the boundaries as described by Article 2 of the 1854 Treaty that were sold by the United States prior to the ratification of the treaty were not part of the reservation and were subject to taxation. Baraga County Equalization Dep't v. Darcy, MTT Docket No. 29713 (Feb. 23, 1982).

In 1991, a district court held that lands sold by the United States prior to the ratification of the 1854 Treaty were a part of the reservation. Keweenaw Indian Bay Cmty., 784 F.Supp. at 424-25. See also note 1, supra. After this ruling, Plaintiff filed a motion in district court to hold the state of Michigan in contempt for failing to prevent Baraga Township and Baraga County from seeking taxes on those lands sold prior to the 1854 Treaty. The district court held that the imposition of such taxes was improper in light of the previous ruling that those lands were part of the reservation, but it did not hold the state in contempt, as the state had not been allowed to correct the actions of the town and the county. Keweenaw Bay Indian Cmty. v. State of Michigan, No. 2:87-CV-00278-RHB (W.D.Mich. Nov. 19, 1991).

In 1992, the Michigan state treasurer filed a petition in state court seeking the sale of certain real property held by Plaintiff or its members due to tax delinquencies. Plaintiff and its members objected to the sale of the lands. The state court dismissed the objections of Plaintiff and its members on the ground that the Michigan Tax Tribunal had exclusive jurisdiction over the case, but the court stayed the sale. In March 1993, Plaintiff and its members filed their objections to the sale of the lands with the Michigan Tax Tribunal. In March 1994, the Michigan Tax Tribunal entered a consent judgment with respect to Plaintiff and its members, L'Anse Township, Baraga Township, and Baraga County. The consent judgment found that real property held by Plaintiff or its members that was within the exterior boundaries of the reservation was exempt from ad valorem taxes under the Act. As a result, such property was to be taken off of the assessment rolls and listed as exempt. These exempt properties, however, were placed on a special "tribal assessment roll," and Plaintiff and its members would pay exactly the amount of taxes that would have been due had the properties been kept on the ordinary assessment roll.

From May 1994 to February 1999, the parties followed the dictates of the consent judgment. In February 1999, the Commission sent a bulletin to assessors and equalization directors instructing them to place all real property owned by American Indian communities and their members on the assessment rolls. This decision was based on the Commission's reading of Cass County v. Leech Lake Band of Chippewa Indians, 524 U.S. 103, 118 S.Ct. 1904, 141 L.Ed.2d 90 (1998).

In February 1999, L'Anse Township, Baraga Township, Baraga County, and two of Plaintiff's members filed a writ of mandamus in state court to prevent the Commission from interfering with the consent judgment. The state trial court issued the writ of mandamus. The state court of appeals affirmed, holding that the Commission was barred by principles of res judicata from interfering with the consent judgment. The state supreme court reversed and found that the Commission was not bound by the consent judgment, although the court did not address the validity of ad valorem taxes on real property held by Plaintiff or its members.

In February 2003, the Commission ordered Defendant Arko to place real property held by Plaintiff or its members on the 2003 assessment rolls. Defendant Arko did so and mailed assessment notices to Plaintiff and its members. The Commission also ordered Defendant Arko to place such property on the 1999, 2000, 2001, and 2002 assessment rolls for L'Anse Township and the 2000, 2001, and 2002 assessment rolls for Baraga Township. Defendants L'Anse Township and Baraga Township issued ad valorem tax bills for real property held by Plaintiff or its members that was located within the exterior boundaries of the reservation. Throughout the dispute, Plaintiff and its members continued to abide by the consent judgment and paid the equivalent of the taxes that would have been owed on their holdings of real property if such property were on the ordinary assessment rolls.

II. DISCUSSION

A. THE PROPER INTERPRETATION OF THE 1854 TREATY 1. Standard of Review

This Court reviews the district court's decision on a motion for summary judgment de novo. Turner v. City of Taylor, 412 F.3d 629, 637 (6th Cir. 2005) (citation omitted). The moving party is entitled to summary judgment "if the pleadings, depositions, answers to interrogatories, and admissions on file, together with the affidavits, if any, show that there is no genuine issue as to any material fact and that the moving party is entitled to a judgment as a matter of law." Fed.R.Civ.P. 56(c). The Court must view the facts and all of the inferences drawn therefrom in the light most favorable to the nonmoving party. Matsushita Elec. Indus. Co. v. Zenith Radio Corp., 475 U.S. 574, 587, 106 S.Ct. 1348, 89 L.Ed.2d 538 (1986) (citation omitted).

2. Analysis

The district court did not err in granting summary judgment in favor of Plaintiff on the ground that the 1854 Treaty disallows involuntary alienation of real property held by Plaintiff or its members. While Defendants offered an alternative interpretation of the 1854 Treaty, principles of American Indian treaty construction support the district court's decision.

a. Legal Framework

The Supreme Court's modern jurisprudence with respect to the interaction of state tax laws and treaties with American Indians is based in McClanahan v. State Tax Commission of Arizona, 411 U.S. 164, 93 S.Ct. 1257, 36 L.Ed.2d 129 (1973). In that case, the plaintiff, a Navajo Indian, challenged the state taxation of her income, which was derived solely from activity within the Navajo reservation. Id. at 165-66, 93 S.Ct. 1257. Before addressing the merits of the plaintiff's claim, the Supreme Court emphasized that there was a "deeply rooted" policy of preventing a state from asserting jurisdiction or otherwise interfering with American Indians. Id. at 168, 93 S.Ct. 1257 (citation omitted). Indeed, in Worcester v. Georgia, "Chief Justice Marshall held that Indian nations were `distinct political communities, having territorial boundaries, within which their authority is exclusive, and having a right to all the lands within those boundaries, which is not only acknowledged, but guarantied by the United States.'" Id. (quoting Worcester v. Georgia, 31 U.S. (6 Pet.) 515, 557, 8 L.Ed. 483 (1832)). The notion that American Indians constituted a separate entity not subject to the laws of the state was known as the Indian sovereignty doctrine. The Court noted that under that doctrine, the Court had rejected a state's attempt to tax the lands within an American Indian reservation. Id. at 169, 93 S.Ct. 1257 (citing The New York Indians, 72 U.S. (5 Wall.) 761, 18 L.Ed. 708 (1867); The Kansas Indians, 72 U.S. (5 Wall.) 737, 18 L.Ed. 667 (1867)).

The Court recognized that the Indian sovereignty doctrine had evolved and that there were certain instances where a state could impose its laws on American Indians and on actions that occurred on reservation lands. Id. at 171-72, 93 S.Ct. 1257. The Court explained:

The Indian sovereignty doctrine is relevant, then, not because it provides a definitive resolution of the issues in this suit, but because it provides a backdrop against which the applicable treaties and federal statutes must be read. It must always be remembered that the various Indian tribes were once independent and sovereign nations, and that their claim to sovereignty long predates that of our own Government. Indians today are American citizens. . . . But it is nonetheless still true . . . that "(t)he relation of the Indian tribes living within the borders of the United States . . . (is) an anomalous one and of a complex character. They were, and always have been, regarded as having a semi-independent position when they preserved their tribal relations; not as States, not as nations, not as possessed of the full attributes of sovereignty, but as a separate people, with the power of regulating their internal and social relations, and thus far not brought under the laws of the Union or of the State within whose limits they resided."

Id. at 172-73, 93 S.Ct. 1257 (alterations in the original) (quoting United States v. Kagama, 118 U.S. 375, 381-82, 6 S.Ct. 1109, 30 L.Ed. 228 (1886)) (emphasis supplied).

Turning to the facts in the case, the Supreme Court held that the treaty with the Navajo Indians precluded the state from extending state tax law to Navajo Indians on the reservation. Id. at 174-75, 93 S.Ct. 1257. Although the treaty did not contain an express provision that disallowed state taxation of the Navajo Indians, the Court recognized that the treaty was "not to be read as an ordinary contract agreed upon by parties dealing at arm's length with equal bargaining positions." Id. at 174, 93 S.Ct. 1257. The Court recognized that American Indians, such as the Navajo, signed treaties under duress and in hopes of creating a permanent home for themselves. Id. "It is circumstances such as these which have led this Court in interpreting Indian treaties, to adopt the general rule that `(d)oubtful expressions are to be resolved in favor of the weak and defenseless people who are the wards of the nation, dependent upon its protection and good faith.'" Id. (alteration in the original) (quoting Carpenter v. Shaw, 280 U.S. 363, 367, 50 S.Ct. 121, 74 L.Ed. 478 (1930)). Relying on "this canon of construction" in conjunction with the backdrop of Indian sovereignty, the Court concluded that the treaty established a reservation where the Navajo Indians had exclusive sovereignty under general federal supervision, such that the state could not tax activities on the reservation. Id. at 174-75, 93 S.Ct. 1257.

Treaty construction in favor of American Indians has a well-established pedigree. In The Kansas Indians, the Supreme Court noted:

[E]nlarged rules of construction are adopted in reference to Indian treaties. In speaking of these rules, Chief Justice Marshall says: "The language used in treaties with the Indians shall never be construed to their prejudice, if words be made use of which are susceptible of a more extended meaning than their plain import as connected with the tenor of their treaty."

72 U.S. (5 Wall.) at 760, 18 L.Ed. 667 (quoting Worcester, 31 U.S. (6 Pet.) at 582, 8 L.Ed. 483) (emphasis supplied). Under this principle, the Supreme Court interpreted a treaty with the Miami Indians, which stated that reservation lands were exempt from "levy, sale, execution, and forfeiture," as preventing state taxation of those lands. The Court reasoned:

Applying this principle [of treaty construction] to the case in hand, is it not evident that the words "levy, sale, and forfeiture" are susceptible of meaning, which would extend them to the ordinary proceedings for the collection of taxes? Taxes must be first levied, and they cannot be realized without the power of sale and forfeiture, in case of non-payment. The position, it seems to us, is too plain for argument. The object of the treaty was to hedge the lands around with guards and restrictions, so as to preserve them for the permanent homes of the Indians. In order to accomplish this object, they must be relieved from every species of levy, sale, and forfeiture-from a levy and sale for taxes, as well as the ordinary judicial levy and sale.

Id. at 760-61, 18 L.Ed. 667.

The Supreme Court recently reaffirmed the principle of treaty construction in favor of American Indians in Minnesota v. Mille Lacs Band of Chippewa Indians, 526 U.S. 172, 119 S.Ct. 1187, 143 L.Ed.2d 270 (1999). There, the Court stated: "[W]e interpret Indian treaties to give effect to the terms as the Indians themselves would have understood them." Id. at 196, 119 S.Ct. 1187 (citations omitted). The Court continued: "We have held that Indian treaties are to be interpreted liberally in favor of the Indians, . . . and that any ambiguities are to be resolved in their favor. . . ." Id. at 200, 119 S.Ct. 1187 (citations omitted). See also Winters v. United States, 207 U.S. 564, 576-77, 28 S.Ct. 207, 52 L.Ed. 340 (1908) ("By a rule of interpretation of agreements and treaties with the Indians, ambiguities occurring will be resolved from the standpoint of the Indians. And the rule should certainly be applied to determine between two inferences, one of which would support the purpose of the agreement and the other impair or defeat it.").

b. Application to This Case

The district court did not err in granting summary judgment in favor of Plaintiff. The district court's interpretation of the 1854 Treaty, finding that the treaty prevented involuntary state alienation and therefore state taxation of real property, comports with the backdrop of American Indian sovereignty and principles of treaty construction in favor of American Indians.

The focus of the analysis is Article 11 of the 1854 Treaty, which states, in relevant part, "[T]he Indians shall not be required to remove from the homes hereby set apart for them." Plaintiff asserts that the provision disallows any form of involuntary alienation, including the sale of real property in fulfillment of a tax judgment. In support, Plaintiff offered the expert opinion and report of Dr. Charles E. Cleland ("Cleland"), Distinguished Professor Emeritus of anthropology and ethnohistory at Michigan State University. Cleland observed that, at the time of the 1854 Treaty, the Lake Superior Chippewa were very concerned with the prospect of removal from their homelands, and they were "particularly anxious" to broker an agreement to create permanent reservations for themselves. That agreement, the 1854 Treaty, contained Article 11, which Cleland gave the following interpretation: "Article 11 solemnly guarantees that the signatory band would never be required involuntarily to leave or give up their reservations created by the treaty for any reason." (J.A. at 254.) Cleland opined that imposition of state tax liability on real property, and the concomitant power to place tax liens on real property, "would be fundamentally contrary to the purpose of the treaty, that is, to provide secure and permanent homes for the [Chippewa Indians]." (J.A. at 255.) Cleland came to the ultimate conclusion:

Certainly [the Chippewa Indians] did not understand the idea of taxation as a condition of holding their permanent reservation. If, in 1854 [federal agent] Gilbert had told the [Chippewa Indians] that they had to pay money each year to hold their land, the [Chippewa Indians], who had very limited access to hard currency, would have most certainly objected. In fact, they would not have signed the treaty. Gilbert made this point with Commissioner Manypenny when he reported on the draft treaty. "We found that the points most strenuously insisted upon by them were first the privilege of remaining in the country where they reside and next the appropriation of land for their future homes. Without yielding these points, it was idle for us to talk about a treaty. We therefore agreed to the selection of lands for them in the territory heretofore ceded." (emphasis in the original)

(J.A. at 79) (footnote omitted).

In response, Defendants assert that the Chippewa Indians intended to subject themselves to state taxes under the 1854 Treaty, as they were eager to participate as citizens of the United States and the states where they resided. In support, Defendants offered the expert opinion and report of Dr. Anthony G. Gulig ("Gulig"), an assistant professor at University of Wisconsin-Whitewater. Gulig found that, in the time preceding the 1854 Treaty, "the Lake Superior Chippewas . . . were not merely opposed to removal, but many had taken up land, were well versed in modern agriculture, and took seriously the business of voting and otherwise interacting with the newcomer society around them." (J.A. at 525.) Gulig found that it was the notion of general removal that the Chippewa Indians feared, and, to combat this fear, they sought not merely reservations, but individual property ownership. The Chippewa Indians, in Gulig's opinion, were eager to take on individual allotments pursuant to the 1854 Treaty; indeed, the "most significant challenge to the administration of the allotment provision of the 1854 Treaty, as it turned out, was that the land was not surveyed and allotted to them quickly enough." (J.A. at 553-54.) From the findings that the Chippewa Indians sought individual allotments, Gulig concluded, "[I]t is clear that the Chippewas of Lake Superior . . . knew the economic value and liability of the land they sought to acquire both as reservations and as individual allotments." (J.A. at 555.) Defendants also presented the expert opinion and report of Dr. Emily Greenwald ("Greenwald"), who opined that, at the very latest, the Chippewa Indians knew in 1919 that the land they held individually could be taxed. Greenwald, however, admitted that "[i]t is not clear whether [the Chippewa Indians] knew that their lands became taxable when title was conveyed" when they signed the 1854 Treaty. (J.A. at 607.)

In our view, the language of Article 11 of the 1854 Treaty is ambiguous. It is unclear whether the provision precluded all forms of involuntary alienation, including the sale of lands in satisfaction of tax liabilities, or only the general removal of the Chippewa Indians from the reservation area. As made amply clear by Supreme Court precedent, this Court must read this ambiguity in favor of Plaintiff and its members, and against the backdrop of the Indian sovereignty doctrine and the notion that American Indian tribes enjoy quasi-sovereignty. This backdrop reinforces Plaintiff's interpretation that the treaty disallowed involuntary state tax sales, and thus state taxation, of real property held by Plaintiff or its members. Moreover, this Court must read the 1854 Treaty in favor of one inference if such inference supports the purpose of the treaty and the opposing inference subverts such purpose. Winters, 207 U.S. at 576-77, 28 S.Ct. 207. In this case, the purpose of the 1854 Treaty was to provide a permanent home for the Chippewa Indians, a purpose that would be weakened by the interpretation of Defendants through the sanctioning of involuntary alienation of land held by Plaintiff or its members through tax sales. Even setting aside these canons of treaty construction, which are a matter of law and thus support the district court's grant of summary judgment, Plaintiff's interpretation is much more persuasive. As the district court stated: "It defies logic to believe that the Indians would have signed a treaty ceding over seven million acres to the United States, knowing that they could lose the land they kept as a reservation the following year, due to non-payment of taxes." (J.A. at 637.) We agree with Cleland that the Chippewa Indians did not know nor did they have reason to know that, in setting aside a permanent reservation for them, the 1854 Treaty also required the Chippewa Indians to pay taxes each year on allotted land, with the potential of losing those allotted lands.

Defendants' experts provide opinions that we do not find persuasive in the present context. Gulig's report focuses primarily on the desire of Chippewa Indians to own land individually to prevent removal and to join the larger societies of the state and the United States. Assuming this view to be accurate, Gulig's report says little as to whether Chippewa Indians understood that, under the 1854 Treaty, individual allotment and ownership came with the price tag of state taxation. Gulig's report makes clear that the Chippewa Indians sought individual allotments for the benefits such allotments provided, but it does not contain a single piece of evidence that demonstrates that the Chippewa Indians knew that lands allotted under the 1854 Treaty would be subject to taxation and the attendant possibility of involuntary alienation. Gulig relies heavily on the fact that Michigan allowed those American Indians whom the state considered "civilized" to vote in state elections, and the fact that "Indians wanted to participate as citizens of the state, and taxation was an important part of that citizen participation." (J.A. at 531-32.) Besides this unsupported conclusory assertion, Gulig hardly even mentions taxation. Greenwald readily admitted in her report that it was "unclear" whether the Chippewa Indians knew of the tax liabilities of land ownership; she only concluded that by 1919, the Chippewa Indians knew that individually held property was subject to taxation. As noted by the district court, "this conclusion does not enlighten the Court as to what the Indians may have believed at the time the Treaty was signed" and is therefore of little use in interpreting the 1854 Treaty. (J.A. at 634-35 n. 4.)

In their brief to this Court, Defendants make two arguments. First, Defendants argue that Plaintiff's interpretation of the 1854 Treaty cannot stand, as it would create a system of "perpetual tutelage" and would be contrary to a purpose of the 1854 Treaty to "civilize" the Chippewa Indians. (Defs.Br.39.) We disagree. Plaintiff's interpretation merely disallows involuntary alienation; any voluntary form of alienation, assuming the President has allowed such alienation under Article 3 of the treaty, would be permissible. Moreover, as Defendants readily admit, the point of restrictions on alienation of the land was to encourage the "civilizing" of the Chippewa Indians, as there was a "concern that the Native Americans would lose control of the land and thereby end the `civilization' process." (Defs. Br. 39 n. 88.) Thus, Plaintiff's interpretation is more in line with the purpose of "civilizing" the Chippewa Indians by ensuring that they would maintain control of the land by shielding that land from involuntary alienation such as a tax sale.

Second, Defendants argue that, before a tax sale of allotted land could take place, an allotment in fee simple would have to be made, and such allotment was subject to a series of procedures and safeguards, such as ensuring that the allottee was competent to manage the land. This argument is irrelevant. Whether there was procedure in place to ensure an allottee was responsible before an unrestricted allotment took place simply has no bearing as to whether the Chippewa Indians understood that an allotment was coupled with taxation.

The point is that while Plaintiff's and Defendant's interpretations represent competing inferences from ambiguous language in Article 11 of the 1854 Treaty, Plaintiff's interpretation is far more compelling. The Chippewa Indians envisioned land set aside for them permanently; it simply does not make sense that the Chippewa Indians would disapprove of the mass removal of their society but would sanction a gradual removal of individuals through involuntary alienation. As Cleland notes, this is especially true considering that the Chippewa Indians did not have much hard currency to pay annual property taxes. Like the treaty at issue in The Kansas Indians, "The object of the treaty was to hedge the lands around with guards and restrictions, so as to preserve them for the permanent homes of the Indians. In order to accomplish this object, they must be relieved from every species of levy, sale, and forfeiture-from a levy and sale for taxes, as well as the ordinary judicial levy and sale." 72 U.S. (5 Wall.) at 760-61, 18 L.Ed. 667. Likewise, in order to accomplish the object of the 1854 Treaty, the preservation of a permanent home for the Chippewa Indians, Plaintiff and its members must be relieved of every species of involuntary removal, including a levy and sale for taxes. As a matter of law, the district court was required to read the ambiguous language of the 1854 Treaty in favor of Plaintiff, a decision that was also practically sound.

B. ABSENCE OF CLEAR CONGRESSIONAL INTENT TO ALLOW TAXATION 1. Standard of Review

This Court reviews the district court's decision on a motion for summary judgment de novo. Turner, 412 F.3d at 637 (citation omitted). The moving party is entitled to summary judgment "if the pleadings, depositions, answers to interrogatories, and admissions on file, together with the affidavits, if any, show that there is no genuine issue as to any material fact and that the moving party is entitled to a judgment as a matter of law." Fed.R.Civ.P. 56(c). The Court must view the facts and all of the inferences drawn therefrom in the light most favorable to the nonmoving party. Matsushita Elec. Indus. Co., 475 U.S. at 587, 106 S.Ct. 1348 (citation omitted).

2. Analysis

The district court did not err in granting summary judgment in favor of Plaintiff on the ground that Congress has not expressed a clear intent to make alienable the property held in fee simple by Plaintiff or its members within the reservation.

a. Legal Framework

While the 1854 Treaty is properly interpreted as preventing the involuntary alienation of, and thus the taxation of, reservation lands held in fee simple by Plaintiff or its members, Congress may abrogate treaty rights; Congress must, however, clearly express its intent to do so. Mille Lacs Band of Chippewa Indians, 526 U.S. at 202, 119 S.Ct. 1187 (citing United States v. Dion, 476 U.S. 734, 738-40, 106 S.Ct. 2216, 90 L.Ed.2d 767 (1986)). "There must be `clear evidence that Congress actually considered the conflict between its intended action on the one hand and Indian treaty rights on the other, and chose to resolve that conflict by abrogating the treaty.'" Id. at 202-03, 119 S.Ct. 1187 (quoting Dion, 476 U.S. at 740, 106 S.Ct. 2216).

Independent of Congress' power to abrogate American Indian treaty rights, Congress may allow state taxation of American Indian reservation lands, but only if it expresses its clear intention to do so. The seminal case of permitted state taxation of American Indian reservation lands is Goudy v. Meath, 203 U.S. 146, 27 S.Ct. 48, 51 L.Ed. 130 (1906). The plaintiff, a Puyallup Indian, claimed that certain property allotted to him under treaty was exempt from state taxation. Id. at 146, 27 S.Ct. 48. The treaty stated that any land allotted under the treaty was exempt from levy, sale, or forfeiture until the formation of a state constitution and the removal of the land restrictions by the state legislature. Id. at 147, 27 S.Ct. 48. The treaty went on to say that a state legislature could not remove the land restrictions without the consent of Congress. Id. Under the treaty, the plaintiff was allotted certain property in 1886. In 1887, Congress enacted the Indian General Allotment Act, also known as the Dawes Act, 24 Stat. 388. The Dawes Act was legislation that allowed the President to allot reservation lands to individual American Indians. Section 5 of the Dawes Act stated that land allotted to American Indians was freely alienable, after the United States held such allotted land in trust for the allottees for twenty-five years. In 1889, the state of Washington joined the United States, and that same year the state legislature passed a law that lifted the land restrictions in the treaty. Id. In 1893, Congress passed legislation, 27 Stat. 612, that allowed the alienability of land allotted to Puyallup Indians ten years after the passage of that legislation. Id. The plaintiff recognized that Congress had made his allotment freely alienable; however, he argued that Congress had also not expressly repealed the provision in the treaty that protected his allotment from levy, sale, or forfeiture, so that his allotment was not taxable. Id. at 148-49, 27 S.Ct. 48.

The Supreme Court held that the plaintiff's allotment was subject to state taxation. The Court found that while Congress could provide that real property was subject to voluntary alienation but immune from involuntary alienation, Congress' "intent to do so should be clearly manifested." Id. at 149. The Court reasoned that from a general perspective, "it would seem strange to withdraw this protection [against voluntary alienation] and permit the Indian to dispose of his lands as he pleases, while at the same time releasing it from taxation." Id.

In McClanahan, discussed above, the Court, in addition to discussing treaty construction, also addressed congressional approval of state taxation of American Indians and their property on a reservation:

State laws generally are not applicable to tribal Indians on an Indian reservation except where Congress has expressly provided that State laws shall apply. It follows that Indians and Indian property on an Indian reservation are not subject to state taxation except by virtue of express authority conferred upon the State by act of Congress.

411 U.S. at 170-71, 93 S.Ct. 1257 (internal quotation marks and citation omitted) (emphasis supplied).

In Yakima, the Supreme Court addressed congressional approval of state taxation of reservation land held by American Indians under the Dawes Act and the Burke Act of 1906, 34 Stat. 182. The Dawes Act, passed in 1887, "empowered the President to allot most tribal lands nationwide without the consent of the Indian nations involved." 502 U.S. at 254, 112 S.Ct. 683. As explained, supra, Section 5 of the Dawes Act required that each allotted parcel be held in trust by the United States for twenty-five years, after which the parcel would be free from restrictions on alienation. Id. Section 6 of the Dawes Act stated that each individual who was the recipient of an allotment had the benefit of and was subject to the laws of state in which he resided. Id.

In 1905, in the case of In re Heff, 197 U.S. 488, 25 S.Ct. 506, 49 L.Ed. 848 (1905), the Supreme Court held that Section 6 of the Dawes Act created plenary state jurisdiction immediately upon the issuance of the allotment, as opposed to the expiration of the twenty-five year trust period. Id. at 255, 112 S.Ct. 683. In response, Congress enacted the Burke Act, which stated that state jurisdiction would lie after the expiration of the twenty-five year trust period. Id. The Burke Act also contained a proviso that allowed the President to issue a patent in fee simple prior to the expiration of the trust period if the President found the allottee to be competent and able to manage her own affairs. Id. "Upon such a premature patenting," the Burke Act stated that "all restrictions as to sale, incumbrance, or taxation of said land" were to be removed. Id. (quoting 34 Stat. 183) (internal quotation marks omitted).

The Yakima plaintiff was an American Indian tribe, who, along with its members, held in fee simple lands that were allotted under the Dawes Act and the Burke Act. Id. at 256, 112 S.Ct. 683. The plaintiff filed an action in district court seeking a declaratory judgment that such lands were exempt from state ad valorem taxation. The Supreme Court disagreed and found that the lands were subject to the state real property tax. The Court first noted that "the power to tax involves the power to destroy," as observed by Chief Justice Marshall in McCulloch v. Maryland, 17 U.S. (4 Wheat.) 316, 431, 4 L.Ed. 579 (1819). Id. at 258, 112 S.Ct. 683. As such,

[a]bsent cession of jurisdiction, or other federal statutes permitting it, we have held, a State is without power to tax reservation lands and reservation Indians. . . . And our cases reveal a consistent practice of declining to find that Congress has authorized state taxation unless it has made its intention to do so unmistakably clear.

Id. (internal quotation marks and citations omitted). The Court found such clear congressional intent in Section 5 of the Dawes Act, where Congress allowed lands allotted under the Dawes Act to be free of restrictions on alienation after the elapse of the trust period. Id. at 263, 112 S.Ct. 683. "[W]hen § 5 rendered the allotted lands alienable and encumberable, it also rendered them subject to assessment and forced sale for taxes." Id. at 263-64, 112 S.Ct. 683. The Court also found that the Burke Act represented a clear intention by Congress that the allotted land be subject to taxation after the trust period, as that was made explicit in the proviso allowing the President to remove restrictions prior to the lapse of twenty-five years. Id. at 264, 112 S.Ct. 683.

In Cass County v. Leech Lake Band of Chippewa Indians, 524 U.S. 103, 118 S.Ct. 1904, 141 L.Ed.2d 90 (1998), the Supreme Court examined the allotment of land under the Nelson Act of 1889. The Nelson Act distributed reservation land in three different ways. Id. at 108, 118 S.Ct. 1904. Under Section 3, the United States allotted parcels to individual tribe members as provided for under the Dawes Act. Id. Under Sections 4 and 5, the United States sold "pine lands" to the highest bidder. Id. Under Section 6, the United States sold the remainder of the reservation land to non-Indian settlers. Id. The plaintiff American Indian band had purchased lands distributed under Sections 4, 5, and 6 to reestablish its land base. Id. The state taxation of these lands was before the Supreme Court. Id. at 110, 118 S.Ct. 1904.

The Court found that the lands were subject to state taxation. Echoing its analysis in Yakima, the Court stated that "when Congress makes reservation lands freely alienable, it is `unmistakably clear' that Congress intends that land to be taxable by state and local governments, unless a contrary intent is `clearly manifested.'" Id. at 113, 118 S.Ct. 1904 (quoting Yakima, 502 U.S. at 263, 112 S.Ct. 683). The Court held that the Nelson Act provided for the public sale of the lands in question, so Congress made those lands freely alienable; as a result, those lands were also subject to taxation. Id. The Court rejected the plaintiff's argument that when the plaintiff reacquired the lands, the lands became nontaxable. Id. at 114, 118 S.Ct. 1904. The Court found that once Congress expressed a clear intent to make the land taxable, Congress must then express a clear intent to make the land nontaxable. Id. Moreover, the Court found that the plaintiff's position would render superfluous a federal statute that allowed the federal government to hold reservation lands in trust so that such land would be nontaxable; Congress had already provided an explicit route for the plaintiff to seek shelter from state taxation. Id.

b. Application to This Case i. The 1854 Treaty

The Indian sovereignty doctrine serves as a backdrop not only for treaty interpretation but also statutory interpretation as well:

The Indian sovereignty doctrine is relevant, then, not because it provides a definitive resolution of the issues in this suit, but because it provides a backdrop against which the applicable treaties and federal statutes must be read. It must always be remembered that the various Indian tribes were once independent and sovereign nations, and that their claim to sovereignty long predates that of our own Government.

McClanahan, 411 U.S. at 172, 93 S.Ct. 1257 (emphasis supplied). This backdrop reinforces the requirement that Congress must make its intent to allow state taxation of reservation lands "unmistakably clear." Yakima, 502 U.S. at 258, 112 S.Ct. 683 (internal quotation marks and citation omitted). Specifically, "[a]bsent cession of jurisdiction, or other federal statutes permitting it, we have held, a State is without power to tax reservation lands and reservation Indians." Id. (internal quotation marks and citation omitted) (emphasis supplied). In McClanahan, the Court stated: "Indians and Indian property on an Indian reservation are not subject to state taxation except by virtue of express authority conferred upon the State by act of Congress." 411 U.S. at 171, 93 S.Ct. 1257 (internal quotation marks and citation omitted) (emphasis supplied).

Defendants argue that the 1854 Treaty is sufficient to demonstrate the clear congressional intent necessary to allow state taxation of reservation lands. We disagree. A treaty is not a federal statute or an act of Congress. In our view, Congress makes its intent to allow state taxation of reservation lands unmistakably clear when it passes a statute to that effect. It is no coincidence that the Supreme Court used phrases such as "federal statutes" and "act of Congress" in describing what would be necessary for the Court to deem state taxation of reservation lands permissible. A treaty simply does not embody this clear congressional intent, as a treaty's ratification only involves the Senate, and thus does not have the same bicameral hurdles of an act of Congress. Defendants argue that because a treaty, under United States law, is self-executing and is the law of the land, it is the equivalent of an act of the legislature. We agree that the effect of a treaty has legal import, as does the effect of an act of legislation; however, the mere fact that a treaty has legal force does not mean it is an act of Congress. All of the cases to which Defendants cite stand only for the proposition that, under United States law, a treaty is self-executing and does not require additional legislation to take effect. See, e.g., Foster v. Neilson, 27 U.S. 253, 314, 2 Pet. 253, 7 L.Ed. 415 (1829), overruled on other grounds by United States v. Percheman, 32 U.S. 51, 7 Pet. 51, 8 L.Ed. 604 (1833). While this is true, this does not mean a treaty is in fact an act of Congress representing that body's will. Concededly, legal authority may be derived from sources other than Congress, but the fact that a treaty has certain legal import is insufficient to establish that a treaty is an act of Congress that represents its will.

Defendants cite two cases of sister circuits where those courts found certain allotted lands, made alienable through treaty, to be taxable by the state. Neither of those cases, however, stand for the proposition that a treaty represents the clear intent of Congress. In Lummi Indian Tribe v. Whatcom County, 5 F.3d 1355 (9th Cir. 1993), the Ninth Circuit relied solely on the alienable character of the allotted land to find that such land was taxable. Indeed, the Ninth Circuit recognized that a treaty did not represent clear congressional intent:

The logic propounded by the Goudy Court and approved by Yakima Nation requires an Indian, even though he receives his property by treaty, to accept the burdens as well as the benefits of land ownership. This proposition may be hard to square with the requirement, recently approved by the Yakima Nation Court, that Congress' intent to authorize state taxation of Indians must be unmistakably clear. The strength of the language in Yakima Nation, however, makes virtually inescapable the conclusion that the Lummi land is taxable if it is alienable.

Id. at 1358 (emphasis supplied). Thus, the Ninth Circuit rested its analysis on the notion that alienability equals taxability, regardless of the source of that alienability; it explicitly found that a treaty was not an expression of clear congressional intent.

Likewise, Thompson v. County of Franklin, 314 F.3d 79 (2d Cir. 2002), does not stand for the proposition that a treaty represents clear congressional intent. In that case, the lead opinion (there was no majority opinion) found that the land in question was freely alienable, although it did not explain from where this alienability derived. The lead opinion then found clear congressional intent to make the land alienable under the Indian Nonintercourse Act of 1790, ("INA"), 25 U.S.C. § 177. Id. at 82. The INA states: "No purchase, grant, lease, or other conveyance of lands, or of any title or claim thereto, from any Indian nation or tribe of Indians, shall be of any validity in law or equity, unless the same be made by treaty or convention entered into pursuant to the Constitution." The lead opinion found that the INA also stood for the fact that a conveyance made by treaty was valid, such that any property properly conveyed would also be subject to taxation. Id. at 82-83. Nowhere in the lead opinion, or any of the opinions, for that matter, did the court assert that a treaty is an expression of clear congressional intent.

The 1854 Treaty is not sufficient to demonstrate a clear congressional intent that the lands at issue in this case be alienable and thus taxable.

ii. The Statutes

Defendants argue that certain statutes demonstrate a clear congressional intent that the lands at issue in this case be alienable. We categorically disagree. Defendants first assert that the 1854 Act, 10 Stat. 598, evidences such clear congressional intent. The 1854 Act authorized the President to negotiate with the Chippewa Indians with respect to certain lands in Minnesota and Wisconsin. Defendants did not raise this argument before the district court, so they may not raise this argument before this Court. Preferred RX, Inc. v. American Prescription Plan, Inc., 46 F.3d 535, 549 (6th Cir. 1995) ("[T]his court will not consider issues not presented to the district court but raised for the first time on appeal."). In fact, Defendants argued in district court that the 1854 Act was inapplicable to the case at hand. Defendants cannot now reverse course and assert the 1854 Act is applicable to this case.

Defendants next rely on the Dawes Act to show a clear congressional intent that the lands at issue be alienable. The record, however, contains absolutely no evidence that L'Anse reservation land was ever allotted under the Dawes Act. Indeed, although all three experts, Cleland, Gulig, and Greenwald, agreed that reservation land was allotted pursuant to the 1854 Treaty, none of the experts claimed that reservation land was allotted pursuant to any other law. Greenwald opined that the Office of Indian Affairs allotted land under the 1854 Treaty utilizing the same procedures as the Dawes Act, but Greenwald never claimed that the Dawes Act ever supplanted the 1854 Treaty as the source of power from which the allotments derived. Likewise, Defendants' reliance on certain acts passed in 1910 and 1913 is misplaced. Those acts, 36 Stat. 855 and 37 Stat. 678, provided that if an allottee died before the trust period expired, the Secretary of the Interior could issue the land in fee simple to the heirs if he found the heirs to be competent. We agree that lands so issued would be taxable, as Congress clearly expressed its intent that such lands were to be held in fee simple and thus would be alienable. The problem, however, is that Defendants muster not even a scintilla of evidence demonstrating that any of the land at issue was indeed issued under either of the acts. In fact, it was impossible for any of the land at issue to have been issued under the 1913 Act, at the least, because Defendant's own expert found that all of the land on the L'Anse reservation had been allotted by 1912.

Defendant's reliance on an act passed in 1922, 42 Stat. 994, is similarly flawed. That act provided that the Secretary of the Interior could allot reservation lands under treaties where the President had such power. In other words, the act made clear that the Secretary of the Interior could exercise presidential power with respect to allotments under treaties. We first note that land within the L'Anse reservation could not have been allotted under the 1922 Act, as all of the land within the reservation had already been allotted by 1912. This fact is dispositive of this argument. Furthermore, we agree with the district court that the 1922 Act was not so much congressional approval of alienability of lands allotted by the Secretary of Interior so much as it was a clarification as to the delegation of the President's power: "[T]he statute appears to be more of an `administrative housekeeping measure,' than an act that was intended to abrogate or change the rights under the 1854 Treaty or address the alienability of such land." (J.A. at 639.)

The record demonstrates that the lands within the L'Anse reservation were allotted pursuant to the 1854 Treaty and not the Dawes Act, the 1854 Act, the 1910 Act, the 1913 Act, nor the 1922 Act. Defendants failed to demonstrate a clear congressional intent that the lands allotted on the L'Anse reservation be alienable and thus taxable.

We realize that the case turns on the formality of whether land was allotted and made alienable through an act of Congress or through some other source, such as the President. Supreme Court jurisprudence makes clear, however, that only Congress has the power to authorize state taxation of American Indian reservation land. If land becomes alienable through the clear intent of Congress, as manifested by statute, such land is also taxable. If land becomes alienable through another source, Congress simply has not spoken as to whether that land should be taxable.

III. CONCLUSION

For the foregoing reasons, we AFFIRM the order of the district court.
