BYBEE, Circuit Judge.
The question presented in this case is whether a non-Indian plaintiff consents to the civil jurisdiction of a tribal court by filing claims against an Indian defendant arising out of activities within the reservation where the defendant is located. Appellant James Smith, who is not a member of the Confederated Salish and Kootenai Tribes (“the Tribes”) of the Flathead Reservation, filed a claim in tribal court against Salish and Kootenai College (“SKC”) arising out of an automobile accident. After a jury returned a verdict in [1129]*1129favor of SKC, Smith sought, an injunction in federal court, alleging that the tribal court lacked subject matter jurisdiction. The tribal courts had previously held that they had jurisdiction to adjudicate the case, and the district court agreed and denied the injunction. Concluding that Smith’s suit is within the first exception of Montana v. United States, 450 U.S. 544, 101 S.Ct. 1245, 67 L.Ed.2d 498 (1981), and the rule in Williams v. Lee, 358 U.S. 217, 79 S.Ct. 269, 3 L.Ed.2d 251 (1959), we affirm.
I. FACTS AND PROCEDURAL HISTORY
Salish and Kootenai College was established by the Confederated Salish and Kootenai Tribes of the Flathead Reservation in Montana. Its mission is “to provide quality postsecondary educational opportunities for Native Americans” and “to promote and help maintain the cultures of the Confederated Tribes of the Flathead Indian Nation.” Mission Statement, http:// www.skc.edu/ (last visited Oct. 17, 2005). SKC is located on tribal land in Pablo, Montana, where it reports 56 full-time instructors, 28 part-time instructors, and more than 1100 students. More than three-quarters of SKC’s students are affiliated with an Indian tribe; more than one-third of these are affiliated with the Confederated Salish and Kootenai. The Tribes incorporated SKC under tribal law in 1977, and a year later SKC was incorporated under state law. Under its articles of incorporation, SKC may sue and be sued in its corporate name in the tribal courts. Its bylaws stipulate that each of the seven members of the Board of Directors must be an enrolled member of the Confederated Salish and Kootenai Tribes. The Tribal Council appoints the members of the Board and may remove them. SKC admits nonmembers of the Tribes.
Smith was enrolled as a student at SKC, although he is a member of the Umatilla Tribe and not of the Confederated Salish and Kootenai Tribes. As part of a course in which he was enrolled, Smith was driving a dump truck, owned by SKC, on U.S. Highway 93 within the Flathead Reservation. Two fellow students were passengers in the truck. Allegedly, the right rear main leaf spring broke, causing the truck to veer sharply and roll over. One passenger, Shad Eugene Burland, was killed, and Smith and a second passenger, James Finley, were seriously injured. Both Burland and Finley were enrolled members of the Confederated Salish and Kootenai Tribes.
The procedural history that culminates in this appeal is complex. Burland’s estate filed a wrongful death action in tribal court against SKC and Smith. SKC filed a cross-claim against Smith. Finley then filed suit against SKC and Smith, and Smith filed his own cross-claim against SKC. The tribal court consolidated the cases, and all claims were settled except Smith’s cross-claim against SKC. Rather than withdrawing his cross-claim and filing in another court, Smith elected to litigate the claim fully in tribal court. The tribal court realigned the parties, naming Smith as the plaintiff and SKC as the defendant. The claims went to a jury, which returned a verdict in favor of SKC.
Following the unfavorable verdict, Smith argued for the first time that the tribal court did not have subject matter jurisdiction. He first sought post-judgment relief in tribal court. At the same time, he filed an appeal of the judgment with the tribal appeals court, which remanded to the tribal trial court to determine jurisdiction. The tribal court determined that it had jurisdiction, and Smith again tiled an appeal with the tribal appeals court. While his second tribal-court appeal was pending, Smith filed a motion for an injunction in federal district court on the ground of lack of jurisdiction, and sought to file his cross-[1130]*1130claim as an original complaint in that court.
Before the federal district court ruled on the injunction, the tribal appellate court issued an opinion affirming the tribal court’s jurisdictional ruling. The federal district court then issued its order finding that the tribal court had jurisdiction and denying the injunction. Smith appealed the judgment of the district court. A panel of our court reversed on the ground that the tribal court lacked jurisdiction over Smith’s claims. Smith v. Salish Kootenai Coll, 378 F.3d 1048 (9th Cir.2004). We vacated that opinion and granted en banc review. 407 F.3d 1267 (9th Cir.2005).
IT. STANDARD OF REVIEW
The question of tribal court jurisdiction is a federal question of law, which we review de novo. Nat’l Farmers Union Ins. Cos. v. Crow Tribe of Indians, 471 U.S. 845, 852-53, 105 S.Ct. 2447, 85 L.Ed.2d 818 (1985); FMC v. Shoshone-Bannock Tribes, 905 F.2d 1311, 1314 (9th Cir.1990). We review findings of fact for clear error. Id. at 1313.
III. ANALYSIS
A
Sixteen years ago, we observed that “[t]here is no simple test for determining whether tribal court jurisdiction exists.” Stock W., Inc. v. Confederated Tribes of the Colville Reservation, 873 F.2d 1221, 1228 (9th Cir.1989). The statement is no less true today. We recently noted that questions of jurisdiction over Indians and Indian country remain a “ ‘complex patchwork of federal, state, and tribal law,’ which is better explained by history than by logic.” United States v. Bruce, 394 F.3d 1215, 1218 (9th Cir.2005) (quoting Duro v. Reina, 495 U.S. 676, 680 n. 1, 110 S.Ct. 2053, 109 L.Ed.2d 693 (1990)).
Our analysis of the tribal court’s jurisdiction starts with the Supreme Court’s decision in Montana, a “pathmarking case concerning tribal civil authority over nonmembers.” Strate v. A-1 Contractors, 520 U.S. 438, 445, 117 S.Ct. 1404, 137 L.Ed.2d 661 (1997); see County of Lewis v. Allen, 163 F.3d 509, 513 (9th Cir.1998) (en banc). In Montana, the Court found that tribal courts have two bases for their authority. First, tribes possess inherent power “necessary to protect tribal self-government [and] to control internal relations.” Montana, 450 U.S. at 564, 101 S.Ct. 1245. This includes the inherent power “to determine tribal membership, to regulate domestic relations among members, and to prescribe rules of inheritance for members.” Id. Second, tribes possess such additional authority as Congress may expressly delegate. Strate, 520 U.S. at 445, 117 S.Ct. 1404; Montana, 450 U.S. at 564, 101 S.Ct. 1245. As no party contends that Congress has expressly granted the Confederated Salish and Kootenai Tribes the authority to hear this suit, we will consider only whether the Tribes have such inherent authority. See United States v. Lara,, 541 U.S. 193, 210, 124 S.Ct. 1628, 158 L.Ed.2d 420 (2004).
“Indian tribes have long been recognized as sovereign entities, ‘possessing attributes of sovereignty over both their members and their territory.’ ” Babbitt Ford, Inc. v. Navajo Indian Tribe, 710 F.2d 587, 591 (9th Cir.1983) (quoting United States v. Wheeler, 435 U.S. 313, 323, 98 S.Ct. 1079, 55 L.Ed.2d 303 (1978) (quoting United States v. Mazurie, 419 U.S. 544, 557, 95 S.Ct. 710, 42 L.Ed.2d 706 (1975))). The basis for tribal jurisdiction is the tribes’ inherent need to define the terms for enrollment, to determine the continuing status of their members, and to regulate relations among their members. Strate, 520 U.S. at 459, 117 S.Ct. 1404; Montana,, 450 U.S. at 563-64, 101 S.Ct. 1245, Owing to their historical status as “dependent sovereign[s]” within the United States, the [1131]*1131tribes hold territory reserved by the United States for the tribes as their principal physical asset. Lara, 541 U.S. at 229, 124 S.Ct. 1628 (Souter, J., dissenting). The tribes retain legislative and adjudicative jurisdiction to provide for disposition of reserved lands and to regulate activities on those lands.
In general, “the inherent sovereign powers of an Indian tribe do not extend to the activities of nonmembers of the tribe.” Montana, 450 U.S. at 565, 101 S.Ct. 1245. This principle is “subject to two exceptions: The first exception relates to nonmembers who enter consensual relationships with the tribe or its members; the second concerns activity that directly affects the tribe’s political integrity, economic security, health, or welfare.” Strate, 520 U.S. at 446, 117 S.Ct. 1404. The Court first identified these two exceptions in Montana. There, it explained that
Indian tribes retain inherent sovereign power to exercise some forms of civil jurisdiction over non-Indians on their reservations, even on non-Indian fee lands. [1] A tribe may regulate, through taxation, licensing, or other means, the activities of nonmembers who enter consensual relationships with the tribe or its members, through commercial dealing, contracts, leases, or other arrangements.[2] A tribe may also retain inherent power to exercise civil authority over the conduct of non-Indians on fee lands within its reservation when that conduct threatens. or has some direct effect on the political integrity, the economic security, or the health or welfare of the tribe.
Montana, 450 U.S. at 565-66, 101 S.Ct. 1245 (citations omitted).1
The Court’s recent cases, and our own experience with the Montana exceptions, demonstrate that there: are two facts courts look to when considering a tribal court’s civil jurisdiction over a case in which a nonmember is a party. First, and most important, is the party status of the nonmember; that is, whether the nonmember party is a plaintiff or a defendant. As Justice Souter observed in Nevada v. Hicks, “ti]t is the membership status of the unconsenting party, not the status of real property, that counts as the primary jurisdictional fact.” 533 U.S. 353, 382, 121 S.Ct. 2304, 150 L.Ed.2d 398 (2001) (Souter, J., concurring). The Court has repeatedly demonstrated its concern that tribal courts not require “defendants who are not tribal members” to “defend [themselves against ordinary claims] in an unfamiliar court.” Strate, 520 U.S. at 442, 459, 117 S.Ct. 1404. Second, the Court has placed some store in whether or not the events giving rise to the cause of action occurred within the reservation. See Hicks, 533 U.S. at 360, 121 S.Ct. 2304 (“The ownership status of land ... is only one factor to consider... .”). Within the reservation, “[t]o be sure, Indian tribes retain inherent sovereign power to exercise some forms of civil jurisdiction over non-Indians ... even on [1132]*1132non-Indian fee lands,” Montana, 450 U.S. at 565, 101 S.Ct. 1245, but subject to an exception not relevant here, “there can be no assertion of civil authority beyond tribal lands.” Atkinson Trading Co. v. Shirley, 532 U.S. 645, 658 n. 12, 121 S.Ct. 1825, 149 L.Ed.2d 889 (2001).
The interaction of these factors—the status of the parties and the connection between the cause of action and Indian lands—is complex. Nevertheless, the cases proride some guidance for our discussion, and we can summarize them as follows. First, where the nonmembers are the plaintiffs, and the claims arise out of commercial activities within the reservation, the tribal courts may exercise civil jurisdiction. See Williams v. Lee, 358 U.S. 217, 79 S.Ct. 269, 3 L.Ed.2d 251 (1959). Second, where the nonmembers are defendants, the Court has thus far held that the tribes lack jurisdiction, irrespective of whether the claims arose on Indian lands. Sec Hicks, 533 U.S. at 356, 121 S.Ct. 2304 (claims arose on Indian fee lands); Montana, 450 U.S. at 547, 101 S.Ct. 1245 (claims arose on non-Indian lands within the reservation). Our own cases, however, suggest that whether tribal courts may exercise jurisdiction over a nonmember defendant may turn on how the claims are related to tribal lands.2 Finally, where neither party is a tribal member the tribe lacks jurisdiction to adjudicate claims arising from an accident on a public highway within the reservation. Strate, 520 U.S. at 456-59, 117 S.Ct. 1404.
The Court has drawn an important observation from this history. It has “never held that a tribal court had jurisdiction over a nonmember defendant.” Hicks, 533 U.S. at 358 n. 2, 121 S.Ct. 2304. Nevertheless, it has “le[ft] open the question of tribal-court jurisdiction over nonmember defendants in general.” Id.3
We next consider the status of the parties to this litigation and whether the claims are related to tribal lands.
B
Smith’s status as a nonmember is clear. James Smith is a not a member of [1133]*1133the Confederated Salish and Kootenai Tribes. He is a member of the Umatilla Tribe, but for purposes of determining the tribal civil jurisdiction of the Salish and Kootenai Tribal Courts, he is a nonmember. See Hicks, 533 U.S. at 377, 121 S.Ct. 2304; see also Duro v. Reina, 495 U.S. 676, 695-96, 110 S.Ct. 2058, 109 L.Ed.2d 693 (1990).
What is less clear is whether Smith is a plaintiff or a defendant. The original suits were filed against Smith and SKC by Burland’s estate and Finley; in that action, Smith was named as a defendant. Smith did not challenge the tribe’s jurisdiction; instead, he filed a cross-claim against SKC, which had filed its own cross-claim against Smith. Prior to trial, the parties resolved all the claims except for Smith’s cross-claim against SKC. The tribal court realigned the parties, and Smith became the plaintiff.
In the posture in which this case came to us, Smith is the plaintiff. It is irrelevant for our purposes that Smith was originally named as a defendant. Courts may realign parties, according to their ultimate interests, whether the realignment has the effect of conferring or denying subject matter jurisdiction on the court. See Standard Oil Co. of Cal. v. Perkins, 347 F.2d 379, 382 (9th Cir.1965); see also F ED. R. CIV. P. 19(a) (“If the person should join as a plaintiff but refuses to do so, the person may be made a defendant, or, in a proper case, an involuntary plaintiff.”); 1A Charles Alan Weight & Mary Kane Kane, Law Of Federal Courts 177-78 (6th ed.2002),
We next turn to the status of the defendant, SKC. SKC is neither a Tribe nor a member of the Tribes. Although in the original suit, the Confederated Salish and Kootenai Tribes were sued as a defendant along with Smith and SKC, the Tribes were dismissed on the ground that they had not waived their immunity in tribal court. SKC did not contend then and does not contend here that it shares the Tribes’ immunity. Nor does SKC contend that it is eligible for tribal membership, which under the Tribes’ constitution is limited to natural persons.
Civil tribal jurisdiction is not limited to matters affecting the tribe qua tribe or- its members qua members. “[T]ribal sell-government” is at the heart of tribal jurisdiction. Montana, 450 U.S. at 564, 101 S.Ct. 1245. Tribes may govern themselves through entities other than formal tribal leadership. Of course, not every enterprise that is owned or staffed by members of a tribe may be considered a tribal entity for purposes of tribal jurisdiction, see Atkinson Trading, 532 U.S. at 657, 121 S.Ct. 1825, but we have previously recognized that there are entities that are sufficiently identified with the tribe that they may be considered to be “tribal.”
Whether an entity is a tribal entity depends on the context in which the question is addressed. See Dille v. Council of Energy Res. Tribes, 801 F.2d 373, 376 (10th Cir.1986) (stating that “the definition of an Indian tribe changes depending upon the purpose of the regulation or statutory provision under consideration”). It is nevertheless useful to look at analogous cases, outside the area of tribal civil jurisdiction, where courts have been called upon to identify tribal entities. In Pink v. Modoc Indian Health Project, Inc., 157 F.3d 1185 (9th Cir.1998), we considered whether the Modoc Indian Health Project was a “tribe” and therefore exempt from the definition of a covered “employer” in Title Y!i. See 42 U.S.C. § 2000e(b) (2003). We found that Modoc was a “nonprofit corporation created and controlled by the Alturas and Cedarville Rancherías, both federally recognized tribes.” Pink, 157 F.3d at 1187. [1134]*1134Modoc’s board of directors were appointed by federally recognized tribes and “served as an arm of the sovereign tribes, acting as more than a mere business.” Id. at 1188. We concluded that Modoc was exempt. Our holding is consistent with decisions in other circuits. See, e.g., Hagen v. Sisseton-Wahpeton Cmty. Coll., 205 F.3d 1040, 1043 (8th Cir.2000) (community college chartered, funded, and controlled by Tribe is a tribal agency entitled to sovereign immunity); Duke v. Absentee Shawnee Tribe of Okla. Hous. Auth., 199 F.3d 1123, 1125, 1126 (10th Cir.1999) (housing authority was “an enterprise designed to further the economic interests of the Absentee Shawnee tribe, and the tribe has exclusive control over the appointment and removal of its decisionmakers”; holding that the housing authority was exempt under Title VII); Dillon v. Yankton Sioux Tribe Hous. Auth., 144 F.3d 581, 583 (8th Cir. 1998) (for Title VII purposes, “ ‘a housing authority, established by a tribal council pursuant to its powers of self-government, is a tribal agencyt,]’ .... rather than a separate corporate entity created by the tribe” (quoting Weeks Constr., Inc. v. Oglala Sioux Hous. Auth., 797 F.2d 668, 670 (8th Cir.1986))); Dille, 801 F.2d at 373 (holding that a council composed of tribes to manage their energy resources was a tribe for Title VII purposes).
By contrast, in NLRB v. Chapa De Indian Health Program, Inc., 316 F.3d 995 (9th Cir.2003), we considered whether the Chapa-De Indian Health Program was subject to subpoena by the National Labor Relations Board. Chapa-De had been authorized by the Rumsey Indian Ranchería, a federally recognized tribe, and was a “tribal organization” for purposes of the Indian Self Determination Act, 25 U.S.C. § 450b(l). None of its board of directors was a member of the Rumsey Tribe, although there were tribal members on the advisory board. Almost half of Chapa-De’s patients and its employees were not Native Americans, and it operated facilities on non-Indian land. We concluded that, although Chapa-De served the health needs of the tribe, its labor relations were not “an intramural activity related to self-governance.” Chapa De, 316 F.3d at 1000. Where the standard was “whether the NLRB ‘plainly lack[ed]’ jurisdiction,” we concluded that “jurisdiction [was] not plainly lacking.” Id. at 997, 1001 (quoting EEOC v. Karuk Tribe Hous. Auth., 260 F.3d 1071, 1077 (9th Cir.2001)).
SKC is located on tribal lands on the Flathead Reservation, is incorporated under tribal and state law, and is described in its articles of incorporation as “[a] tribal corporation.” SKC may sue and be sued in its corporate name in tribal court. Under SKC’s bylaws, the Tribal Council appoints the board of directors, who must be members of the Tribes, and may remove members of the board. Although SKC does not claim that it is immune from suit in tribal courts, the Tribes created it and continue to exercise some control over the institution. Most students receiving degrees are Native Americans, and thirty-four percent of students are from the Confederated Salish and Kootenai Tribes. The college favors Native Americans in hiring, and about forty percent of faculty members are Indians. Even though the Tribes do not fund the college, SKC has been identified as a “tribal governmental agency.” See Bartell v. Am. Home Assurance Co., 310 Mont. 276, 49 P.3d 623, 624 (2002) (referring to finding in federal district court). On the basis of this record, the Tribal Court of Appeals concluded that “SKC is a tribal entity closely associated with and controlled. by the Tribes. For purposes of determining jurisdiction, it must be treated as a tribal entity.” Similarly, the district court found that “SKC is a tribal entity or an arm of the tribe for purposes of federal Indian law regarding tribal court jurisdiction.”
[1135]*1135We do not disagree with these assessments. This ease is much closer to Modoc and the Eighth Circuit’s decision in Hagen than it is to Cha,pa De. Like the Modoc Indian Health Project, SKC is a nonprofit corporation created as a “tribal corporation.” See Pink, 157 F.3d at 1188. As in Hagen, and unlike Chapa De, SKC’s directors are members of the Tribes, selected and subject to removal by the Tribal Council. Chapa De, 316 F.3d at 1000; Hagen, 205 F.3d at 1042. The college, though open to nonmembers such as Smith, is located on tribal lands within the reservation and serves the Confederated Salish and Kootenai Tribes, unlike the Chapa De health program, which served tribal members and nonmembers in four facilities, none of which was on the reservation. Chapa De, 316 F.3d at 997, 1000. We conclude that SKC is a tribal entity and, for purposes of civil tribal court jurisdiction, may be treated as though it were a tribal “member.”
We next turn to whether the claims bear some connection to Indian lands. This fact is significant, though not dispositive. In Hicks, the Court emphasized that “Montana, applies to both Indian and non-Indian land. The ownership status of the land, in other words, is only one factor to consider.” Hicks, 533 U.S. at 360, 121 S.Ct. 2304; see also id. at 381, 121 S.Ct. 2304 (Souter, J., concurring) (stating that “a tribe’s remaining inherent civil jurisdiction to adjudicate civil claims arising out of acts committed on a reservation depends in the first instance on the character of the individual over whom jurisdiction is claimed, not on the title to the soil on which he acted”). Our inquiry is not limited to deciding precisely when and where the claim arose, a concept more appropriate to determining when the statute of limitations runs or to choice-of-law analysis. Rather, our inquiry is whether the cause of action brought by these parties bears some direct connection to tribal lands. See Allstate Indent. Co. v. Stump, 191 F.3d 1071, 1073-74 (9th Cir.1999); Stock W. Corp. v. Taylor, 964 F.2d 912, 919-20 (9th Cir.1992) (en banc).
Smith brought two claims against SKC. First, he alleged that SKC was both negligent and strictly liable for its failure to maintain the track and its leaf spring. Second, he alleged spoliation of evidence. Smith suffered his injuries on U.S. Highway 93, which, as a federal highway within the reservation, is neither tribal land nor controlled by members of the Tribes. See Strate, 520 U.S. at 454-55, 117 S.Ct. 1404. Both of Smith’s claims, however, implicated SKC’s actions on the college campus, not on the highway. Unlike the, accident in Strate, where the plaintiff alleged that the defendants’ negligence on public roads caused her injuries, Smith alleged negligence occurring on the reservation, on lands and in the shop controlled by a tribal entity, SKC.
His spoliation claim similarly implicated SKC’s actions at the college. Smith alleged that SKC destroyed notes from the post-accident investigation and that this destruction interfered with his ability to pursue his claims. SKC admitted that at least one of its employees took notes of interviews with students concerning the accident and the notes were “no longer available.” The record is not clear where the notes were created or destroyed, though the district court assumed the destruction occurred at SKC. Whether or not the notes were in fact lost or destroyed on tribal lands, SKC had control over the notes. For our purposes, Smith’s claim arose out of activities conducted or controlled by a tribal entity on tribal lands.
C
We finally consider whether the tribal courts had sufficient interest to justify the [1136]*1136exercise of subject matter jurisdiction in this case. We recognize that Smith’s suit does not fit obviously within the two exceptions set out in Montana. Smith is not engaged in any of the illustrative “consensual relationships” described in Montana: “commercial dealing, contracts, leases, or other arrangements.” 450 U.S. at 565, 101 S.Ct. 1245. Any contractual relationship Smith had with SKC as a result of his student status is too remote from his cause of action to serve as the basis for the Tribes’ civil jurisdiction. See Atkinson Trading, 532 U.S. at 656, 121 S.Ct. 1825; Strate, 520 U.S. at 457, 117 S.Ct. 1404. Smith might fit within the second Montana exception, which allows for tribal jurisdiction where the conduct of a non-member “threatens or has some direct effect on the ... economic security, or the health or welfare of the tribe.” Montana, 450 U.S. at 566, 101 S.Ct. 1245. The Court in Montana cited Williams, the case most closely analogous to Smith’s, as an example of both the first and second exceptions. Id. at 565-66, 101 S.Ct. 1245. Denying jurisdiction to the tribal court would have a direct effect on the welfare and economic security of the tribe insofar as it would seriously limit the tribe’s ability to regulate the conduct of its own members through tort law. See infra pp. 125-27. But, because we conclude that Smith’s agreement to invoke the jurisdiction of the tribal court fits more comfortably within the first exception, we need not decide whether the second also applies.
Although vce find that Smith’s claims do not fit easily with the literal examples cited in the first Montana exception, we nevertheless believe that the Tribes’ exercise of civil jurisdiction is consistent with the principles set forth in Montana and succeeding cases. This case, unlike the Court’s decisions in Hicks, Strate, and Montana,, involves a nonmember plaintiff. In this regard Smith is similarly situated to the principal case cited as an example of the Montana exceptions: Williams ». Lee. This is important, because as a plaintiff Smith chose to appear in tribal court. We are of the opinion that, even though Ms claims did not arise from contracts or leases with the Tribes, Smith could and did consent to the civil jurisdiction of the Tribes’ courts. And in this case, the exercise of tribal jurisdiction is consistent with the limited sovereignty of the Tribes.
In Williams, Hugh Lee, a non-Indian, brought suit in Arizona state court against Paul Williams, who was a Navajo Indian. Williams purchased goods at Lee’s store on the reservation and failed to pay for them. Williams argued that exclusive jurisdiction lay in the tribal courts because Arizona had not accepted concurrent jurisdiction under a congressional act. The Supreme Court agreed. Noting that the Navajo courts “exercise broad criminal and civil jurisdiction which covers suits by outsiders against Indian defendants,” the Court found that it was “immaterial that respondent is not an Indian. He was on the Reservation and the transaction with an Indian took place there.” 358 U.S. at 222, 223, 79 S.Ct. 269.
The Court’s recent decisions in Hicks and Strate reaffirm the validity of Williams. Most recently, in Hicks, the Court cited Williams as an example of “private individuals who voluntarily submitted themselves to tribal regulatory jurisdiction by the arrangements that they ... entered into.” 533 U.S. at 372, 121 S.Ct. 2304. Elsewhere the Court made dear that Williams was a case involving “claims brought against tribal defendants.” Id., at 358 n. 2, 121 S.Ct. 2304; see also Strate, 520 U.S. at 457, 117 S.Ct. 1404; Three Affiliated Tribes v. Wold Eng’g, 467 U.S. 138, 148, 104 S.Ct. 2267, 81 L.Ed.2d 113 (1984). Similarly, in Strate, the Court [1137]*1137was careful to frame the issue as concerning “the adjudicatory authority of tribal courts over personal injury actions against defendants who are not tribal members.” 520 U.S. at 442, 117 S.Ct. 1404 (emphasis added); see also id, (holding that “tribal courts may not entertain claims against non members arising out of accidents on state highways” (emphasis added)).
Smith is within the Williams rule. Smith comes to this proceeding as the plaintiff, in full control of the forum in which he prosecutes his claims against SKC. Although he did not have a prior contractual relationship with a tribal member, he brought suit against SKC, a tribal entity, for its allegedly tortious acts committed on tribal lands. We do not think that civil tribal jurisdiction can turn on finely-wrought distinctions between contract and tort. See W. Page Keeton, et al., Prosser And Keeton On Torts 4-5 (5th ed.1984).4 As in Williams, we think it was “immaterial that [Smith] is not [a member]” once he chose to bring his action in tribal court. Williams, 358 U.S. at 223, 79 S.Ct. 269.
The Supreme Court has referred to Montana’s principles as “pertaining] to subject-matter, rather than merely personal, jurisdiction.” Hicks, 533 U.S. at 367 n. 8, 121 S.Ct. 2304; see also Wilson v. Marchington, 127 F.3d 805, 813 (9th Cir. 1997). The Court, however, has never defined Indian tribal “subject matter jurisdiction” with the same precision as we use that term when speaking of the subject matter jurisdiction vested and circumscribed by Article III. In the federal courts, “[s]ubject-matter jurisdiction ... functions as a restriction on federal power, and contributes to the characterization of the federal sovereign.” Ins. Corp. of Ire. Ltd. v. Compagnie des Bauxites de Guinee, 456 U.S. 694, 702, 102 S.Ct. 2099, 72 L.Ed.2d 492 (1982). As a consequence, parties to a suit in federal court “may not confer jurisdiction ... by stipulation,” California v. LaRue, 409 U.S. 109, 113 n. 3, 93 S.Ct. 390, 34 L.Ed.2d 342 (1972), abrogated on other grounds by 44 Liquormart, Inc. v. Rhode Island, 517 U.S. 484, 515, 116 S.Ct. 1495, 134 L.Ed.2d 711 (1996), or other “ ‘prior action or consent of the parties,’ ” Owen Equip. & Erection Co. v. Kroger, 437 U.S. 365, 377 n. 21, 98 S.Ct. 2396, 57 L.Ed.2d 274 (1978) (quoting Am. Fire & Cas. Co. v. Finn, 341 U.S. 6, 17, 71 S.Ct. 534, 95 L.Ed. 702 (1951)). Indeed, even though Smith invoked the jurisdiction of the tribal courts, he may still challenge the court’s subject matter jurisdiction on appeal. See Am. Fire & Cas., 341 U.S. at 17-18, 71 S.Ct. 534; Capron v. Van Noorden, 6 U.S. (2 Cranch) 126, 2 L.Ed. 229 (1804).
In contrast to the strictures of federal court jurisdiction, “tribal adjudicatory jurisdiction over non-members is ... ill-defined.” Hicks, 533 U.S. at 376, 121 S.Ct. 2304 (Souter, J., concurring) (internal quotation marks omitted; alteration in original). In Strate, the Court observed that “in civil matters ‘the existence and extent of a tribal court’s jurisdiction will require a careful examination of tribal sovereignty, the extent to which that sovereignty has been altered, divested, or diminished, as well as a detailed study of relevant statutes, Executive Branch policy as embodied [1138]*1138in treaties and elsewhere, and administrative or judicial decisions.’ ” 520 U.S. at 449, 117 S.Ct. 1404 (quoting Nat'l Farmers Union Ins. Cos. v. Crow Tribe of Indians, 471 U.S. at 855-56). More recently, in Hicks, the Court identified this “careful examination” Hicks, 533 U.S. at 399, 121 S.Ct. 2304 (O’Connor, J., concurring), as “a proper balancing of state and tribal interests.” Id. at 374, 121 S.Ct. 2304.
The first Montana exception recognizes that tribes may exercise jurisdiction over nonmembers of the tribe who enter into “consensual relationships” with the tribe or its members. 450 U.S. at 565, 101 S.Ct. 1245. Nonmembers of a tribe who choose to affiliate with the Indians or their tribes in this way may anticipate tribal jurisdiction when their contracts affect the tribe or its members. The principle comes with its own limitation: “A nonmember’s consensual relationship in one area ... does not trigger tribal civil authority in another.... ” Atkinson Trading, 532 U.S. at 656, 121 S.Ct. 1825. Thus, for example, by their mere presence within a reservation and their “actual or potential receipt of tribal police, fire, and medical services,” nonmembers “ha[ve] not consented to the Tribes’ adjudicatory authority.” Id. at 655, .121 S.Ct. 1825. Simply entering into some kind of relationship with the tribes or their members does not give the tribal courts general license to adjudicate claims involving a nonmember. See Boxx v. Long Warrior, 265 F.3d 771, 776 (9th Cir.2001) (a non-Indian’s “socially consensual” relationship with an Indian cannot serve as the basis for tribal civil jurisdiction).
The Court’s “consensual relationship” analysis under Montana resembles the Court’s Due Process Clause analysis for purposes of personal jurisdiction. “The Due Process Clause protects an individual’s liberty interest in not being subject to the binding judgments of a forum with which he has established no meaningful ‘contacts, ties, or relations,’ ” the “constitutional touchstone” being “whether the defendant purposefully established ‘minimum contacts’ in the forum State.” Burger King Corp. v. Rudzewicz, 471 U.S. 462, 471-72, 474, 105 S.Ct. 2174, 85 L.Ed.2d 528 (1985) (quoting Int’l Shoe Co. v. Washington, 326 U.S. 310, 316, 319, 66 S.Ct. 154, 90 L.Ed. 95 (1945)). Thus, the “ ‘unilateral activity of those who claim some relationship with a nonresident defendant cannot satisfy the requirement of contact with the forum State;’ ” rather it must be “actions by the defendant himself that create a ‘substantial connection.’ ” Id. at 474, 105 S.Ct. 2174 (quoting Hanson v. Denckla, 357 U.S. 235, 253, 78 S.Ct. 1228, 2 L.Ed.2d 1283 (1958), and McGee v. Int’l Life Ins. Co., 355 U.S. 220, 223, 78 S.Ct. 199, 2 L.Ed.2d 223 (1957)). In its due process analysis, the Court has emphasized the need for “predictability to the legal system” so that the defendant can “reasonably anticipate being haled into court.” World-Wide Volkswagen Corp. v. Woodson, 444 U.S. 286, 297, 100 S.Ct. 559, 62 L.Ed.2d 490 (1980).
We refer to the due process cases not to question whether the exercise of tribal civil jurisdiction is in fact subject matter juris-, diction, but to reinforce our observation that a jurisdictional analysis that includes a “proper balancing” of state and tribal interests employs a test more flexible than those defining the strict notions of subject matter jurisdiction under Article III. This is evident in the fact that the Court has held that “consensual relationships” may create jurisdiction, a holding inconsistent with federal subject matter jurisdiction, though perfectly consistent with principles of personal jurisdiction. See Stock W., Inc. v. Confederated Tribes of the Colville Reservation, 873 F.2d 1221, 1228-29 (9th Cir.1989) (stating that “even if the consent of Stock West was adequate to confer personal jurisdiction onto the tribal court, the [1139]*1139question of whether the tribal court has subject matter jurisdiction over the case would still not be resolved”; affirming dismissal of federal suit on grounds of comity). We know of no correlative doctrine or practice in the federal system that would allow a party who would not otherwise be subject to a federal court’s subject matter jurisdiction to enter into a consensual relationship—for example, through contract or stipulation—that would confer subject matter jurisdiction on a federal court.
The play in the margins of tribal civil jurisdiction is further evident in the Court’s decisions in Iowa Mutual Insurance Co. v. LaPlante, 480 U.S. 9, 107 S.Ct. 971, 94 L.Ed.2d 10 (1987), and National Farmers Union Insurance Cos. v. Crow Tribe of Indians, 471 U.S. 845, 105 S.Ct. 2447, 85 L.Ed.2d 818 (1985). In both of those cases, a member of the tribe sued a nonmember in tribal court. Although the Court has since observed that it has “never held that a tribal court had jurisdiction over a nonmember defendant,” Hicks, 533 U.S. at 358 n. 2, 121 S.Ct. 2304, in both cases the Court declined to hold that the tribal courts lacked jurisdiction over nonmember defendants. Instead the Court— for reasons of “prudential” exhaustion-remanded the cases to determine whether “the federal action should be stayed pending further Tribal Court proceedings or dismissed.” Iowa Mut, 480 U.S. at 20 n. 14, 107 S.Ct. 971. In those cases, “[r]e-spect for tribal self-government made it appropriate ‘to give the tribal court a “full opportunity to determine its own jurisdiction.” ’ ” Strate, 520 U.S. at 451, 117 S.Ct. 1404 (quoting Iowa Mut., 480 U.S. at 16, 107 S.Ct. 971 (quoting Nat’l Farmers, 471 U.S. at 857, 105 S.Ct. 2447)). Moreover, in those cases the Court expressly declined to extend the rule of Oliphant v. Suquamish Indian Tribe, 435 U.S. 191, 98 S.Ct. 1011, 55 L.Ed.2d 209 (1978)—that tribal courts do not have criminal jurisdiction to punish non-Indians for offenses committed on the reservation—to tribal courts’ civil jurisdiction. The Court explained that, “[i]f we were to apply the Oliphant rule here, it is plain that any exhaustion requirement would be completely foreclosed because federal courts would always be the only forums for civil actions against non-Indians.” Nat’l Farmers, 471 U.S. at 854, 105 S.Ct. 2447. That the Court declined to adopt the Oliphant rule and instead required exhaustion of jurisdiction challenges in the tribal courts necessarily implies that tribal courts retain some civil jurisdiction to decide cases involving nonmembers—'“that the answer to the question whether a tribal court has the power to exercise civil subject-matter jurisdiction over non-Indians .... is not automatically foreclosed.” Id. at 855, 105 S.Ct. 2447; see also Strate, 520 U.S. at 449, 117 S.Ct. 1404 (stating that “tribal courts have more extensive jurisdiction in civil cases than in criminal proceedings”).
“The power to exercise tribal civil authority over non-Indians derives not only from the tribe’s inherent powers necessary to self-government and territorial management, but also from the power to exclude nonmembers from tribal land.” Babbitt Ford, Inc. v. Navajo Indian Tribe, 710 F.2d 587, 592 (9th Cir.1983) (citing Merrion v. Jicarilla Apache Tribe, 455 U.S. 130, 141-44, 102 S.Ct. 894, 71 L.Ed.2d 21 (1982)). If the power to exclude implies the power to regulate those who enter tribal lands, the jurisdiction that results is a consequence of the deliberate actions of those who would enter tribal lands to engage in commerce with the Indians. It is true that “a tribe has no authority over a nonmember until the nonmember enters tribal lands or conducts business with the tribe,” Merrion, 455 U.S. at 142, 102 S.Ct. 894, but we think that no lesser principle should govern those who voluntarily enter a tribal courtroom seeking compensation [1140]*1140from tribal members.5 Indeed, there may be circumstances in which a nonmember plaintiff may have no forum other than the tribal courts in which to bring his claims.6 We hold that a nonmember who knowingly enters tribal courts for the purpose of filing suit against a tribal member has, by the act of filing his claims, entered into a “consensual relationship” with the tribe within the meaning of Montana.7
So long as the Indians “remain a ‘separate people, with the power of regulating their internal and social relations,’.... [making] their own substantive law in internal matters, and ... enforcing] that law in their own forums,” tribal courts will be critical to Indian self-governance. San-for Clara Pueblo v. Martinez, 436 U.S. 49, 55-56, 98 S.Ct. 1670, 56 L.Ed.2d 106 (1978) (citations omitted) (quoting United States v. Kagama, 118 U.S. 375, 381-82, 6 S.Ct. 1109, 30 L.Ed. 228 (1886)); see Iowa Mut., 480 U.S. at 14, 107 S.Ct. 971, The Tribes’ system of tort is an important means by which the Tribes regulate the domestic and commercial relations of its members. Tort liability has historically been a means for compensating injured parties and punishing guilty parties for their willful or negligent acts.
Through his suit, Smith asked the Confederated Salish and Kootenai tribal court to discipline one of their own and order a tribal entity, SKC, to compensate him for the damages he suffered allegedly at its hands. The Tribes have a strong interest [1141]*1141in regulating the conduct of their members; it is part of what it means to be a tribal member. The Tribes plainly have an interest in compensating persons injured by their own; indeed, in this case, there were two members of the Confederated Salish and Kootenai tribes who also suffered allegedly because of SKC’s negligent actions.
If Smith has confidence in the tribal courts, we see no reason to forbid him from seeking compensation through the Tribes’ judicial system. Had the jury awarded compensation to Smith, we have little doubt that we would not have entertained a claim by SKC that the tribal courts lacked jurisdiction to enter judgment against it and in favor of a tribal nonmember. Having made that choice, Smith cannot be heard to complain that the judgment was not in his favor.
IV. CONCLUSION
For the forgoing reasons, the judgment of the district court is
AFFIRMED.
