OPINION
Appellant Jill Gavie challenges the trial court’s application of sovereign immunity to an Indian tribal business corporation alleged to have engaged in tortious conduct on and off the reservation. We affirm, finding no warrant for this court to refuse to apply sovereign immunity, and finding that the respondent tribal business corporation did not expressly waive its immunity.
FACTS
Appellant alleges sexual harassment, pregnancy and race discrimination, civil rights violations, and various related torts arising from her employment with respondent Little Six, Inc., and the conduct of three Little Six officers. The alleged illegal acts occurred both on the Shakopee Mdewakanton Sioux Community reservation and at Little Six’s corporate headquarters in Shakopee, off the reservation. Appellant is also suing the corporate officers individually, but these claims are not at issue on this appeal.
Appellant obtained employment with respondent Little Six, a business corporation formed by tribal ordinance of the Shakopee Mdewakanton Sioux Community. Little Six is registered as a foreign corporation in Minnesota. The corporation issued one share of stock when it was formed in 1991 and that share is owned by the Shakopee Mdewakanton Sioux Community as a whole. Each voting member of the community is entitled to one vote on corporate matters placed before the community for a vote.
Little Six’s articles of incorporation, developed under authority of the community’s business ordinances, provide that the purpose of the corporation is to “improve the business, financial or general welfare of the Corporation, Members of the Corporation, *282 and the Community.” The articles provide that the corporation has the same sovereign immunity from suit as the community except for claims by the community or members of the corporation against the corporation. But the corporation reserves the “power to sue and * * * to consent to be sued” provided that a “contract or other commercial document * * * [specifies] the terms and conditions of such consent.” And “consent to suit by the Corporation * * * [may not] be deemed a waiver of any of the rights, privileges and immunities of the Community.”
The trial court granted summary judgment for Little Six on grounds that the corporation was immune from suit and, because Little Six had not consented to be sued, the trial court held that it had no subject matter or personal jurisdiction. The trial court held that registering with the secretary of state did not amount to a waiver of sovereign immunity.
ISSUES
1. Does sovereign immunity apply to tribal business corporation activity on and off the reservation?
2. Has Little Six expressly waived its sovereign immunity?
ANALYSIS
The trial court’s summary judgment was granted as a matter of law on undisputed facts and is reviewed without deference to the trial court’s determination.
Hubred v. Control Data Corp.,
1. Sovereign immunity
The trial court had subject matter and personal jurisdiction over Little Six, a tribal business corporation, but sovereign immunity is a separate inquiry.
Duluth Lumber & Plywood Co. v. Delta Dev., Inc.,
Tribal sovereignty has been recognized in the law since 1832.
Worcester v. Georgia,
Tribal sovereignty of the Shakopee Mde-wakanton Sioux Community is further evidenced by its organization under the Indian Reorganization Act of 1934, 25 U.S.C.A § 476 (Supp.1995) (hereinafter Section 16 tribal government corporation). The purpose of the Act is “to rehabilitate the Indian’s economic life and to give [Indians] a chance to develop the initiative destroyed by a century of oppression and paternalism.”
Mes-calero Apache Tribe v. Jones,
2. Application of Sovereign Immunity to Tribal Corporation
Courts have applied sovereign immunity to both tribal governments and their business activities.
Maryland Casualty Co. v. Citizens Nat’l Bank,
Congressional intent to treat some tribal business corporations as entities distinct from the tribe itself is manifested in the Indian Reorganization Act, 25 U.S.C. § 477 (Supp.1990) (hereinafter Section 17 tribal business corporation). Section 17 is the counterpart to Section 16, which governs tribal government corporations.
Parker Drilling Co.,
The model articles of incorporation for Section 17 tribal business corporations contain a “sue and be sued” clause that constitutes a waiver of sovereign immunity and subjects the tribal business corporation, but not the tribe, to suit “consistent with the [Indian Reorganization Act’s] purpose.” Vetter, 36 Ariz.L.Rev. at 175. In this way tribal business corporation property is risked, leaving the tribal property safe from judgments.
Atkinson,
Against this history of the common law and the Indian Reorganization Act, application of sovereign immunity to tribal business corporations has begun to further erode because “tribal activities conducted outside the reservation present different considerations.”
Mescalero Apache Tribe,
In
Mescalero,
dealing with a tribe’s off-reservation ski resort operation, the U.S. Supreme Court refused to apply sovereign immunity when the state asserted its regulatory power to tax the enterprise.

In
Dixon v. Picopa Constr. Co.,
Here, Little Six claims it is an arm of the tribal government, but this claim has no merit. Neither the form nor the substance of the Shakopee Mdewakanton Sioux Community business ordinances or Little Six’s articles of incorporation support this conclusion.
See Mescalero,
Another court has reached a similar conclusion on claims arising from acts that occurred off the reservation but where the alleged cause of action was for breach of contract.
Padilla v. Pueblo of Acoma,
The Ninth Federal Circuit rejected the reasoning of
Padilla,
holding that congressional silence regarding off-reservation commercial activities is “compelling, if not controlling * * * [sjince only Congress can limit the scope of tribal immunity and it has not done so.”
In re Greene, 980
F.2d 590, 594 (9th Cir.1992),
cert denied,
— U.S.-,
The Minnesota Supreme Court has held that an Indian organization incorporated under a tribe’s business ordinances is a separate legal entity that could be sued on a breach of contract claim arising off the reservation.
Duluth Lumber,
Appellant argues that because Minnesota is a “Public Law 280” state, this court has jurisdiction over civil causes of action to which Indians are parties, and “those civil laws of such State * * * that are of general application to private persons or private property shall have the same force and effect within such Indian country as they have else *285 where within the State.” 28 U.S.C. § 1360 (1988).
Congress enacted Public Law 280 out of concern for lawlessness on some reservations, inadequate tribal law enforcement, and the state court’s lack of jurisdiction over Indians.
Bryan v. Itasca County,
Ambiguities must be resolved in favor of the tribe, and the failure of Public Law 280 to address the status of tribal business corporations must be narrowly construed.
Bryan,
In sum, appellant’s contentions on appeal find support only in an Arizona State Court decision, and to a lesser extent in New Mexico. And Congress has left the issue unresolved. The Indian Reorganization Act was intended to provide a waiver of sovereign immunity to tribal business corporations, but only when accomplished by articles of incorporation. And Public Law 280 has unclear ramifications for tribal business corporations. Our declaration that a tribal business eorpo-ration has no sovereign immunity for off-reservation activities is unwarranted in the absence of direction from Congress, the Supreme Court of the United States, or the Minnesota Supreme Court.
Although appellant argues persuasively that a tribal business corporation conducting business off the reservation should be held legally accountable for its actions, because our supreme court has not spoken, and “[b]e-cause of the supremacy of federal law, we are bound to recognize the doctrine of tribal sovereign immunity, even if we were to find valid public policy reasons to hold it inapplicable in this case.”
Atkinson,
3. Sovereign immunity must be expressly waived
Because Little Six is entitled to immunity on the claims stated in this case, we must next determine if Little Six waived that immunity. Tribes, like Congress, may waive sovereign immunity to advance economic interests that may be thwarted if third parties perceive the tribes to be legally unaccountable for their business transactions.
United States v. Oregon,
Minnesota courts find a waiver of immunity for Indian tribal businesses where
*286
there exists express language such as that contained in a “sue and be sued” clause.
Duluth Lumber,
Appellant argues that by registering as a foreign corporation and consenting to service of process, Little Six has waived immunity. But consent to service does not amount to a waiver of sovereign immunity. The Ninth Federal Circuit heard and rejected this argument in
Snow v. Quinault Indian Nation,
4. Equal Protection under the Indian Civil Rights Act
Appellant argues in passing that she is denied equal protection under the Indian Civil Rights Act of 1968, 25 U.S.C. § 1302(8) because Little Six allows suit against it by the tribe and tribal members but not others. “As separate sovereigns preexisting the Constitution, tribes have historically been regarded as unconstrained by those constitutional provisions framed specifically as limitations on federal or state authority.”
Santa Clara Pueblo,
DECISION
The decision of the trial court to grant summary judgment in favor of respondent Little Six, Inc. is compelled under the existing state of the law on sovereign immunity. Little Six has not expressly waived its sovereign immunity.
Affirmed.
Notes
. The trial court had personal jurisdiction over Little Six by virtue of its registration as a foreign corporation in Minnesota and appointment of an agent for service of process. Minn.Stat. § 303.13, subd. 1 (1992);
Rykoff-Sexton, Inc. v. American Appraisal Assoc., Inc.,
. We note that "there is notably absent [from P.L. 280] any conferral of state jurisdiction over the tribes themselves.”
