This case requires us to revisit and further define the allocation of sovereign powers between the Penobscot Nation (the Nation) and the State of Maine. The question before us is whether the decision of the Penobscot Nation Tribal Council to terminate the employment of a community health nurse constitutes an “internal tribal matter” within the meaning of the Maine Indian Claims Settlement Act of 1980, 25 U.S.C. §§ 1721 -1735. The district court held that it does not. We disagree. That employment termination decision is an “internal tribal matter” and, as such, cannot be challenged in the courts of Maine pursuant to the Maine Human Rights Act (MHRA), Me.Rev.Stat. Ann. tit. 5, § 4551 et seq.
I.
The undisputed material facts are recounted thoroughly in the district court’s opinion.
See Penobscot Nation v. Fellencer,
Fellencer subsequently filed suit in the Maine Superior Court against the Penobscot Nation, claiming that the Nation had terminated her1 employment (1) without due process and (2) “due to her- race and/or' national origin in violation of the Maine Human Rights Act.” She claims that subsequent to her' termination the community nurse position was posted with an express preference for Indian applicants. The Nation filed a motion to dismiss, which was denied.
On October 20, 1997, the Nation filed the instant action in the federal district court seeking a preliminary injunction to stay the state court proceeding. Cross motions for summary judgment were filed. On March 13, 1998, the distract court denied the Nation’s request for a preliminary injunction and entered judgment in favor of Fellencer, thereby permitting the state court case to proceed. The district court’s denial of the preliminary injunction can be reversed where there has been a “misapplication of the law to particular facts” or an “application of the wrong legal standard.”
See Planned Parenthood League of Mass. v. Bellotti,
II.
The backdrop to the state and federal court proceedings is some familiar history. In the early 1970s, the Nation (in concert with the Passamaquoddy Tribe and others) filed suit claiming nearly two-thirds of Maine’s land mass as their ancestral homelands.
See Passamaquoddy Tribe v. Maine,
As a result of the settlement, the relationship between the Penobscot Nation and Maine is governed primarily by the Implementing Act (state) and the Settlement Act (federal). The Implementing Act provides as follows:
[T]he Passamaquoddy Tribe and the Pe-nobscot Nation, within their respective In-dian territories, shall have, exercise and enjoy all the rights, privileges, powers and immunities, including, but without limitation, the power to enact ordinances and collect taxes, and shall be subject to all the duties, obligations, liabilities and limitations of a municipality of and subject to the laws of the State, provided, however, that internal tribal matters, including membership in the respective tribe or nation, the right to reside within the respective Indian territories, tribal organization, tribal government, tribal elections and the use or disposition of settlement fund income shall not be subject to regulation by the State.
Me.Rev.Stat. Ann. tit. 30, § 6206(1) (emphasis added). We have previously recognized that “[a]s to state law, the Penobscot Nation and Maine expressly agreed that, with very limited exceptions, the Nation is subject to the laws of Maine.”
Akins,
The Implementing Act was
incorporated
by reference into the Settlement Act, 25 Ú.S.C. §§ 1721-1735.
See
25 U.S.C. § 1721(b)(3). In ratifying the Implementing Act, Congress sought to balance Maine’s interest in continuing to exercise jurisdiction over the Nation’s land and members (which it had done without interference for' almost two centuries),
see Bottomly v. Passamaquoddy Tribe,
While the settlement represents a compromise in which state authority is extended over Indian territory to the extent provided in the Maine Implementing Act, ... the settlement provides that henceforth the tribes will be free from state interference in the exercise of their internal affairs. Thus, rather than destroying the sovereignty of the tribes, by recognizing their power to control their- internal affairs ... the settlement strengthens the sovereignty of the Maine Tribes.
S. Rep. No. 96-957, at 14; H.R.Rep. No. 96-1353, at 14-15, reprinted in 1980 U.S.C.C.A.N. at 3790.
III.
As the language of the Implementing Act and the federal legislative history make clear, the critical phrase to analyze in determining the scope of tribal sovereignty is “internal tribal matter's.” When the Nation acts on “internal tribal matters,” its actions are not subject to regulation by the state. Me.Rev.Stat. Ann. tit. 30, § 6206(1). Because the phrase “internal tribal matters” was adopted by the federal Settlement Act, the meaning of that phrase raises a question of federal law.
See Akins,
*709
Before we examine the language of the Implementing Act, we must acknowledge some general principles that inform our analysis of the statutory language. First, Congress’ authority to legislate over Indian affairs is plenary and only Congress can abrogate or limit an Indian tribe’s sovereignty. See U.S. CONST., art. I, § 8, cl. 3;
Motion v. Mancari,
A. The La nguage of the Statute
The Implementing Act preserves the Nation’s sovereignty with respect to
internal tribal matters, including membership in the respective tribe or nation, the right to reside within the respective Indian territories, tribal organization, tribal government, tribal elections and the use or disposition of settlement fund income....
Me.Rev.Stat. Ann. tit. 30, § 6206(1). While the list of exemplars following “internal tribal matters” informs the meaning of that term, the list is not exclusive or exhaustive. In fact, we declared in
Akins
that the exemplars “provide limited guidance.”
Akins,
B. The Akins Precedent
Akins
was our first occasion for addressing the allocation of sovereign powers between the Nation and the State of Maine pursuant to the Implementing Act and the Settlement Act. The Nation had adopted a policy allowing only enrolled members of the tribe who lived on the reservation to be eligible for timber permits to harvest timber on tribal lands.
See Akins,
We identified five considerations in
Akins
that were persuasive in characterizing the grant of timber rights as an “internal tribal matter.” These considerations were: (1) the disputed policy regulated only tribal members; (2) the policy related to lands acquired by the Nation with federal funds received for that purpose, and the lands were considered “Penobscot Indian Territory”; (3) the policy affected the Nation’s ability to regulate its natural resources; (4) at least on its face, the policy did not implicate or' impair' the interest of the State of Maine; and (5) the recognition that the timber harvesting policy involved an “internal tribal matter” was consistent with prior legal understandings.
Akins,
Evaluating all of these considerations, with particular emphasis on the interest of the State of Maine, prior legal understandings, and the nature of Fellencer’s position, we conclude that the decision of the Nation to terminate Fellencer’s employment was an “internal tribal matter.”
C. The Akins Considerations
1. Within the Tribe
Although Fellencer, unlike Akins, is not a member of the Nation, and hence the effect of the decision at issue is not limited to tribal members, the decision to terminate Fellencer as the community health nurse affects many tribal members but only one non-tribal member (Fellencer). This limited impact beyond the Nation distinguishes this case from
Penobscot Nation v. Stilphen,
2 & 3. Land and, Natural Resources
The second and third considerations in
Akins
related to the commercial use of tribal lands (“the very land that defines the territory of the Nation,”
Akins,
J. Interest of Maine
As a generality, Maine has a strong interest in protecting all employees against discrimination through its Human Rights Act.
See
Me.Rev.Stat. Ann. tit. 5, § 4552;
see also Maine Human Rights Comm’n v. Local 1361, United Paperworkers Int'l
Union,
5. Prior Legal Understandings
Prior legal understandings strongly support the Nation’s claim of exemption from challenge in state court to its employment termination decision. In the employment discrimination context, Congress exempted Indian tribes from Title VII’s definition of “employer” in the original passage of the Civil Rights Act of Ih64. 42 U.S.C. § 2000e(b) (“[T]he term ‘employer’ means a person engaged in an industry affecting commerce .... Such term does not include ... an Indian tribe”).
3
The Supreme Court has characterized this exemption as “Congress’ recognition of the longstanding federal policy of providing a unique legal status to the Indians in matters of tribal employment,” and it characterized Congressional intent as a
“policy of furthering Indian self-government.” Morton v. Mancari,
General federal Indian civil rights law, outside the employment discrimination context, further bolsters the conclusion that Fellencer’s claim involves an “internal tribal matter.” Even though Indian tribes were exempted from Title VII coverage, Congress subsequently enacted the Indian Civil Rights Act of 1968 (ICRA), 25 U.S.C. §§ 1301-41, made applicable to the Penobscot Nation through the Settlement Act, 25 U.S.C. § 1725(h).
See Akins,
As fundamental as federal court jurisdiction has been to the protection of the civil lights enumerated in section 1302(8), the Supreme Court held in
Santa Clara Pueblo v. Martinez,
These prior legal understandings (both the Title VII exemption and the ICRA’s grant of exclusive jurisdiction to tribal courts) are particularly important because they inform the intent of Congress in the adoption of the Settlement Act. We “have long presumed that Congress acts against the background of prior law.”
Akins,
Indeed, the Senate Report on the Settlement Act explicitly cited with approval to
Santa Clara Pueblo v. Martinez,
The Senate Report on the Settlement Act also noted that the Act strengthened the Nation’s sovereignty “by recognizing [the Pe-nobscot’s] power to control their internal affairs and by withdrawing the power which Maine previously claimed to interfere in such matters!.]” S. Rep. 96-957, at 14. The Report predicates the Nation’s right to be free from state interference on the Nation’s “inherent sovereignty” as recognized in
Bottomly,
In summary, these prior legal understandings provide strong support for classifying a claim of national origin discrimination based on the termination of Fellencer’s employment as an “internal tribal matter.”
D. The Nature of the Posit ion at. Issue
Apart from the statutory language, judicial precedent, legislative history and federal In-dian common law, the Nation’s employment of a community health nurse has particular “internal tribal matter” implications because *713 of the statutory origins of the position. The community nurse position from which Fel-lencer was dismissed is funded by the Indian Self-Determination and Education Assistance Act of 1975 (ISDA), 25 U.S.C. § 450 et seq. Congress therein declared its policy to “respond to the strong expression of the Indian people for self-determination by assuring maximum Indian participation in the direction of ... Federal services to Indian communities.” 25 U.S.C. § 450a(a); see also S.Rep. No. 102-392, at 7 (1992), reprinted in 1992 U.S.C.C.A.N. at 3949 (1992 amendments to Indian Health Care Improvement Act)(“health care provided by people of one’s own culture is the most appropriate, and results in better utilization of health care services”). Believing that the administration of such sei-vices by Indians was “crucial to the realization of self-government,” 25 U.S.C. § 450(a)(1), Congress included an employment preference for Indians in the legislation. 25 U.S.C. § 450e(b) (requiring that “preferences and opportunities for training and employment . .. shall be given to Indians”).
This employment preference for Indians distinguishes the Nation’s community nurse position from any position in a regular municipal government.
Cf.
Implementing Act, Me.Rev.Stat. Ann. tit. 30, § 6204 (subjecting Nation generally to same state jurisdiction as state exercises over municipalities). Clearly, Maine municipalities cannot employ similar preferences. The uniqueness of the federal employment preference counsels against the application of Maine law in this employment discrimination context. In light of the Supreme Court’s description of such preferences in
Morton v. Mancan,
The judgment of the district court is reversed; the case is remanded for the entry of judgment in favor of the Nation and the issuance of an injunction if it is deemed necessaiy.
Notes
. We recognize that a decision exempting the Nation from coverage under the MHRA in this case may potentially affect other non-tribal members; i.e., non-members may be discouraged from applying for employment with the Nation. This broader public impact implicates the Slate of Maine’s responsibility for protecting its citizens from impermissible employment discrimination. We address this issue in our discussion of the interest of the State of Maine.
. This position was initially adopted by the MHRC in November 1982 in Ranco v. The Penobscot Nation (case No. E81-0020), and has been the undisturbed interpretation of the Maine Human Rights Commission since that time.
. The district court incorrectly expanded on the holding in
Houlton Band of Maliseet Indians v. Maine Human Rights Commission,
. Two circuits have extended this exemption to bar claims against Indian tribes based on the Age Discrimination in Employment Act (ADEA), 29 U.S.C. §§ 621-34, even though no similar express exemption is contained in the ADEA. These courts premised the implied exemption from federal court jurisdiction over age-based discrimination claims on the Indian tribes' right to self-government.
See EEOC v. Fond du Lac Heavy Equip. and Const. Co.,
.In
Santa Clara Pueblo
a female member of the tribe brought an action claiming the tribe’s policies violated the ICRA’s equal protection clause, 25 U.S.C. § 1302(8). Specifically, the plaintiff asserted that a tribal ordinance which denied tribal membership to the children of female members who marry outside the tribe but not to the children of similarly situated men impermis-sibly discriminated on the basis of gender.
See Santa Clara Pueblo,
. There is one exception, not applicable in this case: Congress has authorized federal court jurisdiction only to hear habeas corpus petitions.
