OPINION
WINFREE, Justice.I. INTRODUCTION
Michael McCrary sued Ivanof Bay Village (Ivanof Bay) and its president, Edgar Shan-gin, under two contracts, alleging breaches of the implied covenants of good faith and fair dealing. The superior court dismissed the suit based on sovereign immunity. McCrary appeals the sovereign immunity ruling, arguing that even though the United States Department of Interior lists Ivanof Bay as a federally recognized Indian tribe, Ivanof Bay has not been formally designated as a federally recognized tribe. We have previously concluded Alaska Native tribes recognized by Congress or the Executive Branch are sovereign under federal law, and MeCrary has not demonstrated this conclusion should be overturned. We therefore affirm the superior court's dismissal of MeCrary's suit.
II. FACTS AND PROCEEDINGS
The United States Department of Interior (Department) annually publishes a list of federally recognized Indian tribes.1 Ivanof Bay2 has been a recognized tribe on the Department's list since the Department issued a "preliminary" list of Alaska Native tribes in 1982.3
In September 2005 MeCrary contracted with Ivanof Bay to oversee its land by performing certain duties, such as securing buildings, in exchange for payment of $1,500 monthly.4 In December 2005 MeCrary and Ivanof Bay cancelled that contract, but Iva-nof Bay agreed McCrary could "store his personal belongings in the tribal building."
In June 2006 McCrary and Ivanof Bay formed a new contract for McCrary to "provide sustainable economic development to the Ivanof Bay Village tribal members." Ivanof Bay agreed to pay McCrary a monthly fee for being "the lead agent in the economic development planning, developing, and management effort." McCrary incurred expenses and assumed contractual obligations exceeding $100,000, of which Shangin had personal knowledge. In September 2006 *339Shangin cancelled the June contract on Iva-nof Bay's behalf without reimbursing McCrary's expenses. McCrary attempted to retrieve his personal property from the tribal building, but Ivanof Bay denied him access.
In October 2008 McCrary sued Ivanof Bay and Shangin in state superior court, alleging breaches of the implied covenants of good faith and fair dealing in the 2005 and 2006 contracts.5 In November McCrary dismissed the case without prejudice and filed a new suit against Ivanof Bay (but not Shan-gin) and the Department in federal district court. McCrary later amended his complaint to include as defendants the Acting Assistant Secretary of Interior for Indian Affairs and the Secretary of Interior. McCrary sought "a declaratory judgment that neither Congress nor the Secretary of the Interior nor any other official of [the Department] ... has recognized the members of [Ivanof Bay] to be a 'federally recognized tribe, and, as a consequence, [Ivanof Bay] does not possess sovereign immunity."
In September 2009 the federal district court dismissed McCrary's complaint for lack of subject matter jurisdiction because the complaint did not raise a federal question. The next day McCrary again sued Ivanof Bay and Shangin in superior court, making the same claims as his previous superior court suit.6 In January 2010 Ivanof Bay and Shangin moved to dismiss MeCrary's suit, arguing in part that the superior court lacked subject matter jurisdiction because "Ivanof Bay is a federally recognized [tJribe protected by sovereign immunity." Ivanof Bay and Shangin relied on our conclusion in John v. Baker that Alaska Native tribes on the Department's list of federally recognized tribes are sovereign entities entitled to sovereign immunity.7 McCrary opposed the motion, arguing the list had no effect because Ivanof Bay has not been formally designated as a federally recognized tribe.
In June 2010 the superior court dismissed McCrary's suit for lack of subject matter jurisdiction because Ivanof Bay and Shangin were "protected by sovereign immunity." McCrary appeals.8
III. STANDARD OF REVIEW
"The applicability of sovereign immunity presents a question of law that we review de novo."9 We adopt "the rule that is most persuasive in light of precedent, reason, and policy." 10
IV. DISCUSSION
McCrary contends the superior court's implicit determination that Ivanof Bay is a federally recognized tribe was the basis for its ruling that Ivanof Bay and Shan-gin are immune from suit in state court. McCrary argues the superior court erred by dismissing his complaint because Congress has neither recognized Ivanof Bay as an Indian tribe nor delegated authority to the Department to do so. He concludes that Ivanof Bay and Shangin are not entitled to sovereign immunity because Ivanof Bay is not a validly recognized tribe.
McCrary asks us to overrule our September 1999 John v. Baker decision, which concluded that Alaska Native tribes recognized by Congress or the Executive Branch are sovereign under federal law.11 McCrary asserts that the parties in John v. Baker did not adversarially brief the tribal recognition *340issue and therefore our conclusion amounted to dictum, not a holding entitled to recognition under the doctrine of stare decisis. He alternatively contends our conclusion was "originally erroneous" and that we should overrule this aspect of John v. Baker.
In John v. Baker we recognized inherent tribal jurisdiction outside of Indian country, concurrent with state jurisdiction, to adjudicate certain child custody disputes involving tribal members.12 We examined whether Alaska Native tribes are sovereign under federal law: 13 we observed that the Department issued a list of federally recognized tribes in 1993 including most Alaska Native villages and that the list's preamble expressed the Department's intention to "reaffirm the sovereign status of the recognized tribes." 14 The preamble stated that Alaska "villages and regional tribes listed ... have the same governmental status as other federally acknowledged Indian tribes by virtue of their status as Indian tribes with a government-to-government relationship with the United States."15 We concluded that the Department viewed "recognized Alaska villages as sovereign entities." 16
The Federally Recognized Indian Tribe List Act of 1994 (Tribe List Act) directs the Department to publish annual lists of tribes eligible for special programs and services because of their Indian tribe status.17 We stated in John v. Baker that "for those who may have doubted the power of the [Department] to recognize sovereign political bodies, [the] 1994 act of Congress appears to lay such doubts to rest.18 We concluded that the "text and legislative history of the Tribe List Act demonstrate that Congress also views the recognized tribes as sovereign bodies," 19 and it emphasizes that legislative history referring to the recognized tribes' "sovereignty," "quasi-sovereign status," and "government-to-government relationship [with] the United States ... as ... domestic dependent nation[s]." 20 We also noted that the Department continued publishing lists including Alaska Native villages pursuant to this congressionally delegated authority.21 In deference to congressional and executive recognition that listed Alaska Native tribes are sovereign, we expressly recognized their sovereignty in John v. Baker.22
McCrary argues that John v. Baker should not be considered binding precedent because no party in that appeal argued against recognition of the sovereign status of Alaska Native tribes. He contends this legal issue was not tested by the adversarial process. But our conclusion regarding the Executive Branch's tribal recognition and Congress's approval through the Tribe List Act was carefully considered and adopted by the entire court.23 Our conclusion in John v. Baker was not dictum-it was decisional and an essential foundation of the broader holding that Alaska Native tribes, by virtue of their sovereign powers, have concurrent tribal jurisdiction to adjudicate certain child eustody disputes involving tribal members.24
Our precedent is not lightly set aside. We have repeatedly held "that a par*341ty raising a claim controlled by an existing decision bears a heavy threshold burden of showing compelling reasons for reconsidering the prior ruling."25 "We will overrule a prior decision only when clearly convinced that the rule was originally erroneous or is no longer sound because of changed conditions, and that more good than harm would result from a departure from precedent." 26 McCrary does not argue changed conditions and he has not shown that our previous decision was originally erroneous or that departure from this precedent would result in more good than harm. The U.S. District Court for the District of Alaska has held on multiple occasions that the Department has authority to recognize Alaska Native tribes.27 Federal courts of appeals have made similar statements.28 Commentators also acknowledge the Department's authority to recognize tribes.29
If the Department or the courts have misconstrued congressional intent, Congress has had ample opportunity to clarify the Department's authority: the Department published its "preliminary list" of eligible Alaska Native tribes in 1982,30 recognized Alaska Native tribes explicitly in the 1998 list,31 and included Alaska Native tribes on each subsequent list.32 Congress chose not to override those actions when it enacted the Tribe List Act,33 but conversely overrode the Department's omission of one Alaska Indian tribe from the 1998 list.34
*342We conclude McCrary bas not sustained his heavy burden to demonstrate our precedent in John v. Baker should be overturned. Because Ivanof Bay is a federally recognized tribe, it is entitled to sovereign immunity. Ivanof Bay and Shangin, as its president, are immune from suit in state court.35

We AFFIRM the superior court's dismissal of McCrary's suit based on sovereign immunity.36

. The Department's 1993 list did not include the Central Council of Tlingit and Haida Indian *342Tribes of Alaska. In response, Congress passed the Tlingit and Haida Status Clarification Act, Pub.L. No. 103-454, 108 Stat. 4791 (Nov. 2, 1994) codified at 25 U.S.C. §§ 1212, 1213 (2006). In this Act, Congress expressly recognized the Central Council of Tlingit and Haida Indian Tribes of Alaska. Additionally, Congress noted that "[the Secretary does not have the authority to terminate the federally recognized status of an Indian tribe as determined by Congress...." Section 2, Pub.L. No. 103-454, 108 Stat. 4791 (Nov. 2, 1994). We do not believe Congress would expressly impugn the Secretary's authority to terminate congressionally recognized tribes, but fail to also disaffirm the Secretary's power to recognize tribal status. See also Native Vill. of Venetie I.R.A. Council v. State of Alaska, 1994 WL 730893, "10 (D.Alaska Dec. 23, 1994).
. See, e.g., Runyon, 84 P.3d at 439 ("[TJribes have long been recognized as possessing the common-law immunity from suit traditionally enjoyed by sovereign powers." (quoting Santa Clara Pueblo v. Martinez, 436 U.S. 49, 58, 98 S.Ct. 1670, 56 L.Ed.2d 106 (1978))).
. We note the superior court based its dismissal on lack of subject matter jurisdiction. It is unclear whether a tribe's sovereign immunity is merely an affirmative defense or a bar to jurisdiction. Compare Sea Hawk Seafoods, Inc. v. State, 215 P.3d 333, 339 (Alaska 2009) (holding state sovereign immunity is an affirmative defense "that does not affect a court's subject-matter jurisdiction"), with Kiowa Tribe of Okla. v. Mfg. Techs., Inc., 523 U.S. 751, 755-56, 118 S.Ct. 1700, 140 L.Ed.2d 981 (1998) ("We have often noted ... that the immunity possessed by Indian tribes is not coextensive with that of the States.") and Puyallup Tribe, Inc. v. Dep't of Game of State of Wash., 433 U.S. 165, 172, 97 S.Ct. 2616, 53 L.Ed.2d 667 (1977) ("Absent an effective waiver or consent, it is settled that a state court may not exercise jurisdiction over a recognized Indian tribe."). But because Ivanof Bay properly raised sovereign immunity as a defense and we affirm on that ground, we do not need to decide whether dismissal for lack of subject matter jurisdiction was proper.
