Opinion for the Court filed by Circuit Judge GRIFFITH.
Since the days of John Marshall, it has been a bedrock principle of federal Indian law that every tribe is “capable of managing its own affairs and governing itself.”
Cherokee Nation v. Georgia,
This case involves an attempt by a small cluster of people within the California Valley Miwok tribe (“CVM”) to organize a tribal government under the Act. CVM’s chairwoman, Silvia Burley, and a group of her supporters adopted a constitution to govern the tribe without so much as consulting its membership. The Secretary declined to approve the constitution because it was not ratified by anything close to a majority of the tribe. Burley and her supporters—in CVM’s name—then sued the United States, claiming that the Secretary’s refusal was unlawful and seeking a declaration that CVM is organized pursuant to 25 U.S.C. § 476. 1 Because we conclude that the Secretary lawfully refused to approve the proposed constitution, we affirm the district court’s dismissal of Bur-ley’s claim. Burley also argues that the district court erred in denying her motions for leave to file supplemental claims for relief. We conclude that any such error was harmless.

Indian tribes are “unique aggregations possessing attributes of sovereignty over both their members and their territory; they are a separate people possessing the power of regulating their internal and social relations.”
United States v. Mazurie,
Once recognized, a tribe may qualify for additional federal benefits by organizing its government under the Act. “[Section 476 of the Act] authorizes any tribe ... to adopt a constitution and bylaws, subject to the approval of the Secretary of the Interi- or.”
Kerr-McGee Corp. v. Navajo Tribe of Indians,
Section 476 of the Act provides two ways a tribe may receive the Secretary’s approval for its constitution. The first is, in effect, a safe harbor. Section 476(a) says:
Any Indian tribe shall have the right to organize for its common welfare, and may adopt an appropriate constitution and bylaws, and any amendments thereto, which shall become effective when—
(1) ratified by a majority vote of the adult members of the tribe or tribes at a special election authorized and called by the Secretary under such rules and regulations as the Secretary may prescribe; and
(2) approved by the Secretary pursuant to subsection (d) of this section.
25 U.S.C. § 476(a). Pursuant to subsection (a)(1), the Secretary has promulgated several rules governing special elections. See generally 25 C.F.R. pt. 81. Compliance with these rules is a prerequisite for the Secretary’s approval of a proposed constitution. Among other things, the rales define voter eligibility, id. § 81.6, create tribal-election boards, id. § 81.8, establish voting districts, id. § 81.9, describe voter-registration procedures, id. § 81.11, stipulate conditions for election notices, id. § 81.14, set poll opening and closing times, id. § 81.15, and describe the criteria for ballots, id. § 81.20. According to subsection (d)(1), once shown that the proposed constitution is the product of the § 476(a) process, the Secretary “shall approve the constitution [ ] within forty-five days after the election unless the Secretary finds that the proposed constitution [is] contrary to applicable laws.” 25 U.S.C. § 476(d)(1).- 4
Notwithstanding any other provision of this Act each Indian tribe shall retain inherent sovereign power to adopt governing documents under procedures other than those specified in this section!.]
25 U.S.C. § 476(h)(1). But this greater flexibility in process comes with a cost. Section 476(h) does not provide a safe harbor. As discussed in detail in Part III, the central issue in this case is the extent of the Secretary’s power to approve a constitution under this section.
II.
CVM is a federally recognized Indian tribe. See Indian Entities Recognized and Eligible to Receive Services from the United States Bureau of Indian Affairs, 70 Fed.Reg. 71,194, 71,194 (Nov. 25, 2005). It has a potential membership of 250, 5 but its current tribal council—led by Burley—was handpicked by only a tiny minority. 6 This case is the latest round of sparring between Burley and the federal government over whether the tribe is organized under the Act. Burley’s efforts to organize the tribe began in 2000 when, pursuing the safe harbor procedure of § 476(a), she and a group of her supporters adopted a constitution and requested the Secretary to call an election for its ratification. Section 476(c) required the Secretary to call an election on the proposed constitution within 180 days. For reasons not apparent from the record, the Secretary never called the election. Rather than press the matter, Burley withdrew her request for a vote on the constitution.
A second effort to organize came in 2001, when Burley’s group adopted a new constitution for the tribe. This time, Bur-ley bypassed the § 476(a) process and instead sent the constitution directly to the Secretary for approval. The Secretary informed her that the constitution was defective and the tribe still unorganized.
Perhaps relying on the old adage, Bur-ley made a third attempt in early 2004. Meanwhile, Congress passed the Native American Technical Corrections Act, which added § 476(h). The Secretary then responded to Burley by rejecting her proposed constitution and explaining that she would need to at least attempt to involve the entire tribe in the organizational process before the Secretary would give approval:
Where a tribe that has not previously organized seeks to do so, [the Secretary] also has a responsibility to determine that the organizational efforts reflect the involvement of the whole tribal community. We have not seen evidence that such general involvement was attempted or has occurred with the purported organization of your tribe.... To our knowledge, the only persons of Indian descent involved in the tribe’s organization efforts, were you and your two daughters.
Letter' from Dale Risling, Sr., Superintendent, United States Department of the Interior, Bureau of Indian Affairs-Cent. Cal. Agency, to Silvia Burley (Mar. 26, 2004).
Burley, in CVM’s name, then sued the United States for its failure to recognize the tribe as organized. She also twice motioned for leave to file supplemental claims for relief. The district court dismissed the original complaint for failure to state a claim and also denied the motions for leave.

de novo. Broudy v. Mather,
III.
The Burley faction has chosen not to repeat its effort to organize under § 476(a). Instead, it has tried to organize under § 476(h). Burley argues that, under § 476(h), the Secretar}' had no choice but to approve the proposed constitution. The Secretary reads § 476(h) to allow her to reject any constitution that does not “reflect the involvement of the whole tribal community.” We consider the question within the framework of
Chevron, U.S.A., Inc. v. Natural Resources Defense Council, Inc.,
The Secretary suggests that her authority under § 476(h) includes the power to reject a proposed constitution that does not enjoy sufficient support from a tribe’s membership. Her suggestion is reasonable, particularly in light of the federal government’s unique trust obligation to Indian tribes.
See Seminole Nation v. United States,
The sensibility of the Secretary’s understanding of § 476(h) is especially apparent in a case like this one. Although CVM, by its own admission, has a potential membership of 250, only Burley and her small group of supporters had a hand in adopting her proposed constitution. This anti-majoritarian gambit deserves no stamp of approval from the Secretary. As Congress has made clear, tribal organization
Burley also argues that the district court abused its discretion by denying her motions for leave to file supplemental claims. See Fed.R.Civ.P. 15(d). Any such error was harmless. See Fed.R.Civ.P. 61. Because there has been no fact development in this case, no harm is done by requiring Burley to file her supplemental claims in a new cause of action. See 6A Charles Alan Wright, Arthur R. Miller and Mary Kay Kane, Federal Practice & Procedure § 1506, at 197 (2d ed.1990) (noting that “when joinder will not promote judicial economy or the speedy disposition of the dispute between the parties, refusal to allow the supplemental pleading is entirely justified”).
For the foregoing reasons, the judgment of the district court is
Affirmed.

. In 1999, the Secretary recognized Burley as CVM’s chairperson. The Secretary also entered into a "self-determination contract” with the tribe under the Indian Self-Determination Act. See 25 U.S.C. § 450f. Pursuant to that contract, the tribe received funds for the development of its government. Subsequently, however, the Secretary modified her stance and recognized CVM's leadership only on an interim basis, pending the tribe's organization effort. Burley does not challenge this change.
