I. INTRODUCTION
Two tribes claim to be a child’s tribe for purposes of the Indian Child
Welfare Act (ICWA). The Native Village of Wales claims that the child is a tribal
member, and the Native Village of Chignik Lagoon claims that the child is “eligible for
tribal membership.” After the superior court terminated the biological parents’ parental
rights, Wales moved to transfer subsequent proceedings, including potential adoption,
to its tribal court. Chignik Lagoon intervened in the child in need of aid (CINA) case,
arguing that the child is not a member of Wales under Wales’s constitution and that
transfer of further proceedings to the Wales tribal court was not authorized under ICWA.
The superior court found that the child is a member of Wales and that
Wales is the child’s tribe for ICWA purposes, and the court therefore granted the transfer
of jurisdiction. Chignik Lagoon appeals. We affirm the superior court’s determination
that the child is a member of Wales and that Wales was appropriately designated as the
child’s tribe for ICWA purposes. We also conclude that, given that ruling, Chignik
Lagoon lacks standing to challenge the transfer of proceedings to the Wales tribal court.
II. FACTS AND PROCEEDINGS
Trent O.1 was born in July 2018. Wales considers Trent’s mother and
maternal grandmother to be tribal members, though neither lives in the village of Wales.
Trent tested positive for opiates at birth. On August 6 the Office of
Children’s Services (OCS) filed a non-emergency petition for adjudication of Trent as
a child in need of aid and for temporary custody. Presuming that Trent was eligible for
Wales tribal membership, the superior court proceeded under ICWA. A Wales tribal
representative attended the continued probable cause hearing three days later, and the
notice of rights required by ICWA was sent to Wales.2

 Trent was released from the hospital’s neonatal treatment unit about a
month after his birth, and OCS placed him in a foster home with David and Darla Dunn,
who had already adopted Trent’s cousin. David’s mother is Alaska Native and a Chignik
Lagoon tribal member, and other extended family of the Dunns live in the village of
Chignik Lagoon. Trent interacted with David’s family regularly. Darla testified that
Wales, on the other hand, “never reached out to [her]” while Trent was living with her
and David.
Wales did, however, continue to participate in the court proceedings,
sending a representative to 13 of the 22 hearings. Following a termination trial in August
and September 2020, the court terminated the parental rights of Trent’s parents; they are
not involved in this appeal.
In December 2020 Wales petitioned to transfer post-termination CINA
proceedings to its tribal court, submitting an acceptance of jurisdiction signed by five
tribal court judges and a tribal representative. The guardian ad litem and OCS opposed
the petition, arguing that ICWA’s jurisdictional transfer provision3 did not require
transfer of post-termination proceedings. It was their position that Trent should remain
with the Dunns, who hoped to adopt him.
The superior court agreed that ICWA’s jurisdictional transfer provision did
not apply to post-termination proceedings, but it determined that it nevertheless had
authority to transfer jurisdiction to the Wales tribal court. The court quoted our opinion

in Starr v. George4: “ICWA applies only to specified child custody proceedings, which
are limited to foster care placement, termination of parental rights, preadoptive
placement, and adoptive placement.”5 The court concluded that under the plain language
of ICWA, when a tribe seeks a transfer of jurisdiction to tribal court, a state court should
grant it absent good cause. The court granted the transfer to the Wales tribal court in late
December 2020.
Before the transfer took effect, David, Trent’s foster father, enrolled as a
member of Chignik Lagoon. In early January 2021 Chignik Lagoon filed a motion to
stay the transfer, a motion to intervene, and a petition to invalidate the transfer order.
Chignik Lagoon argued that granting tribal intervention and transfer to Wales was error
and that Chignik Lagoon, not Wales, was Trent’s tribe for ICWA purposes. The superior
court granted the stay without ruling on the other motions.
Wales enrolled Trent as a member on February 13, and on February 24
Wales, having participated in the proceedings for the past few years, moved to formally
intervene.
On April 12 the superior court held an evidentiary hearing to determine
which tribe was Trent’s tribe under ICWA. The Dunns testified about their relationship
with Trent as foster parents and Trent’s interactions with members of Chignik Lagoon.
The court heard from Chignik Lagoon’s ICWA caseworker, who also served on Chignik
Lagoon’s tribal court. She testified about the requirements for tribal membership under
Chignik Lagoon’s constitution, explaining that although Trent was eligible for
membership from the moment the Dunns “picked him up from the hospital . . . due to
[the Dunns’] familial ties from birth,” he was not yet an enrolled member.

 An OCS caseworker testified about early and unsuccessful attempts to place
Trent with family members. She explained that prior to Wales’s transfer request, OCS’s
permanency plan was for Trent to be adopted by the Dunns, and that until the parents’
rights were terminated Wales had never expressed an interest in removing Trent from the
Dunns’ care. The caseworker confirmed that “the Wales Tribe, all along throughout the
life of, up to and through termination, were accepting of the Dunns’ placement and
permanency goal [of] adoption.”
Wales called Anna Oxereok, the president of the Native Village of Wales,
to testify. Oxereok testified that both Trent and his biological mother are members of
Wales and that Trent “was born Inupiat and . . . Kingikmiut.”6 She testified that in
Wales, “when a child becomes orphaned, they’re given to the next kin, to the brother, the
sister, the aunt, the uncle. And that’s the way of protecting our children, protecting our
way is to make sure we keep the children in . . . our tribe.”
Though Oxereok testified she believed Trent “should go to family first,”
she confirmed that the “tribal court ha[d] yet to make any decisions about placement
because the case had[n’t] transferred yet.” She testified that “if [Wales did] get
jurisdiction, . . . [its tribal council] would have a meeting. . . . They’d look his whole case
over again.” Oxereok also testified about the tribe’s interpretation of its constitutional
provision governing tribal membership.
Following the hearing, the court determined that Wales was Trent’s tribe
and ordered jurisdiction transferred to the Wales tribal court. Applying
25 C.F.R. § 23.109, the court found that Wales had “more significant contacts” with

Trent.7 The court concluded that there was no good cause not to transfer jurisdiction to
Wales, and it therefore vacated the stay and ordered the proceedings transferred. The
court also granted Chignik Lagoon’s motion to intervene, vacated all future hearings, and
denied as moot all other outstanding motions — including Wales’s motion for
intervention and Chignik Lagoon’s petition to invalidate the transfer.
Chignik Lagoon appeals. The superior court stayed the transfer order
pending disposition of the appeal.
III. STANDARD OF REVIEW
“We evaluate de novo the scope of tribal jurisdiction and the meaning of
federal statutes.”8 When interpreting a statute we “apply our independent judgment,
interpreting the statute according to reason, practicality, and common sense, considering
the meaning of the statute’s language, its legislative history, and its purpose.”9 “We may
affirm the superior court on any basis supported by the record, even if that basis was not
considered by the court below or advanced by any party.”10
IV. DISCUSSION
We first address whether the superior court erred in determining that Trent
is a member of Wales. We then address whether the superior court erred in determining

7
If a child meets the definition of “Indian child” through more than one tribe,
and the tribes do not agree which tribe should be designated as the child’s tribe for
ICWA purposes, the court must choose the tribe with the “more significant contacts”
with the child. 25 C.F.R. § 23.109(c) (2016). 25 C.F.R. § 23.109(c)(2) lists factors the
court must consider when determining which tribe has “more significant contacts.”

that Wales is Trent’s tribe for ICWA purposes. Last, we address Chignik Lagoon’s
standing to challenge the transfer of post-termination proceedings to the Wales tribal
court.
A. The Superior Court Did Not Err By Deferring To The Tribes’
Membership And Eligibility Determinations.
A federal regulation, 25 C.F.R. § 23.108, defines who decides tribal
membership under ICWA:
(a) The Indian Tribe of which it is believed the child is a
member (or eligible for membership and of which the
biological parent is a member) determines whether the child
is a member of the Tribe, or whether the child is eligible for
membership in the Tribe and a biological parent of the child
is a member of the Tribe, except as otherwise provided by
Federal or Tribal law.
(b) The determination by a Tribe of whether a child is a
member, whether a child is eligible for membership, or
whether a biological parent is a member, is solely within the
jurisdiction and authority of the Tribe, except as otherwise
provided by Federal or Tribal law. The State court may not
substitute its own determination regarding a child’s
membership in a Tribe, a child’s eligibility for membership
in a Tribe, or a parent’s membership in a Tribe.
The superior court concluded that Trent is both a member of Wales and
eligible for membership in Chignik Lagoon, explaining that “if the Native Village of
Wales finds that, under its laws, [Trent] is eligible for membership, it is not this court’s
place to question that determination.” Likewise, the court explained that it “will not, and
cannot, question” Chignik Lagoon’s determination that Trent is eligible for membership.
Chignik Lagoon argues that the superior court erred in its interpretation of
25 C.F.R. § 23.108; it contends that the regulation requires a state court to invalidate a
tribe’s membership determination if, in the court’s view, that determination is

-7- 7628
inconsistent with tribal or federal law. Chignik Lagoon contends that Trent is not
eligible for membership in Wales under either tribal or federal law, and thus the court
erred in concluding that he is a member of Wales.
Chignik Lagoon’s interpretation is inconsistent with the regulation’s
language and purpose. The regulation provides that “[t]he Indian Tribe . . . determines
whether the child is a member of the Tribe . . . except as otherwise provided by Federal
or Tribal law” and a “State court may not substitute its own determination regarding a
child’s membership in a Tribe.”11 We read these words as having a plain meaning: A
tribe has the last word in determining its tribal membership unless federal or tribal law
provides that another entity — such as the state court or the Bureau of Indian Affairs
(BIA) — should make that determination instead.
This interpretation is supported by the regulation’s focus. Titled “Who
makes the determination as to whether a child is a member, whether a child is eligible for
membership, or whether a biological parent is a member of a Tribe?,”12 the regulation
explains which entity makes the determination, not how the determination is made or
what standards should apply.
The Federal Register offers additional insight. The BIA explains in
comments to its ICWA regulations that “Tribes, as sovereign governments, have the
exclusive authority to determine their political membership and their eligibility
requirements.”13 Therefore, “[a] Tribe is . . . . the authoritative and best source of
information regarding who is a citizen of that Tribe and who is eligible for citizenship

of that Tribe.”14 “Thus, the rule defers to Tribes in making such determinations and
makes clear that a court may not substitute its own determination for that of a Tribe
regarding a child’s citizenship or eligibility for citizenship in a Tribe.”15
Court decisions reflect the same rule of deference to the tribe’s exercise of
control over its own membership. The U.S. Supreme Court has long recognized tribes’
“inherent power to determine tribal membership.”16 In John v. Baker we recognized that
“the Supreme Court has articulated a core set of [tribes’] sovereign powers that remain
intact [unless federal law provides otherwise]; in particular, internal functions involving
tribal membership and domestic affairs lie within a tribe’s retained inherent sovereign
powers.”17 We have also “long recognized that sovereign powers exist unless divested,”
and “ ‘the principle that Indian tribes are sovereign, self-governing entities’ governs ‘all
cases where essential tribal relations or rights of Indians are involved.’ ”18
Chignik Lagoon’s argument would require state courts to independently
interpret tribal constitutions and other sources of law and substitute their own judgment
on questions of tribal membership. This argument is directly contrary to the directive of
25 C.F.R. § 23.108. The superior court did not err in concluding that a tribe’s

membership determinations are final and not reviewable by a state court.19
B. The Superior Court Did Not Err By Concluding That Wales Is Trent’s
Tribe For ICWA Purposes.
ICWA defines “Indian child” as a person under 18 who is unmarried and
(a) a member of an Indian tribe or (b) eligible for membership in an Indian tribe and the
biological child of a member of an Indian tribe.20 A state court may recognize only one
tribe as the Indian child’s tribe for ICWA purposes; there are two complementary rules
the court must use to make this determination. The first is in 25 U.S.C. § 1903(5)21:
“Indian child’s tribe” means (a) the Indian tribe in which an
Indian child is a member or eligible for membership or (b), in
the case of an Indian child who is a member of or eligible for
membership in more than one tribe, the Indian tribe with
which the Indian child has the more significant contacts.
The second rule comes from BIA regulations. Under 25 C.F.R. § 23.109,
the court determines the child’s tribal membership in three steps. First, under subsection

19
Other state courts agree. See People ex rel. K.C. v. K.C., 487 P.3d 263, 270
(Colo. 2021) (“[C]itizenship for purposes of ICWA is left exclusively to the control of
each individual nation.”); In re T.W., No. 122,197, 2020 WL 3885923, at *13 (Kan. App.
Jul. 10, 2020) (“The ultimate determination of whether a child is a member of or eligible
for membership of a recognized tribe is solely determined by tribal or federal law.”); In
re L.D., 414 P.3d 768, 773 (Mont. 2018) (“Except as otherwise limited by federal statute
or treaty, Indian tribes have the sole power to determine their membership and
membership eligibility.”); In re E.J.B., 846 S.E.2d 472, 476 (N.C. 2020)
(“[D]etermination [of tribal membership] is committed to the sole jurisdiction of the tribe
. . . . ”); In re N.C.H., 489 P.3d 139, 141 (Or. App. 2021) (“A tribe’s word on the matter
of membership or eligibility for membership is conclusive on th[at] point.”); In re Z.J.G.,
471 P.3d 853, 866 (Wash. 2020) (“Tribes are in the exclusive position to determine the
membership of their own nations, and ICWA . . . recognize[s] and respect[s] the
sovereign power of tribes to decide this highly internal matter.”).

25 U.S.C. § 1903(4).

-10- 7628
(a), if an Indian child is “a member or eligible for membership in only one Tribe, that
Tribe must be designated as the Indian child’s Tribe.”22 Second, under subsection (b),
if “an Indian child meets the definition of ‘Indian child’ through more than one Tribe,
deference should be given to the Tribe in which the Indian child is already a member,
unless otherwise agreed to by the Tribes.”23 And third, under subsection (c), if an Indian
child is “a member in more than one Tribe or the child is not a member of but is eligible
for membership in more than one Tribe,” the court must provide the tribes an opportunity
to decide which should be designated as the Indian child’s tribe.24 If the tribes do not
agree, the state court then considers relevant factors to determine the Indian child’s tribe
based on which tribe has more significant contacts:
(i) Preference of the parents for membership of the child;
(ii) Length of past domicile or residence on or near the
reservation of each Tribe;
(iii) Tribal membership of the child’s custodial parent or
Indian custodian; . . .
(iv) Interest asserted by each Tribe in the child-custody
proceeding;
(v) Whether there has been a previous adjudication with
respect to the child by a court of one of the Tribes; and
(vi) Self-identification by the child, if the child is of sufficient
age and capacity to meaningfully self-identify.[25]
The superior court in this case first found that section 23.109(a) was not

22

applicable because Trent “is eligible for membership in [Chignik Lagoon] and is a
member of [Wales].” The court next found that section 23.109(b) was also inapplicable,
reasoning that although “the regulations state deference should be given to the Tribe in
which the Indian child is already a member,” “should” is not a mandatory phrase and
thus not determinative. Because the tribes were unable to come to an agreement, the
superior court considered the factors listed above in section 23.109(c)(2) and found that
“the only factor that applies here is the ‘interest asserted by each Tribe in the child-
custody proceeding.’ ”26
The court observed that both Chignik Lagoon and Wales had “testified that
they are concerned for [Trent’s] best interests, and that involvement with tribal activities
is important for both Tribes.” But the court found that Wales had “clearly asserted more
interest in this child-custody proceeding.” The court focused on Wales’s substantial
involvement in the CINA case from the outset, noting that “Wales has been treated as
[Trent’s] Tribe for the majority of these proceedings.” Although Chignik Lagoon moved
to intervene in January 2021, the court explained that Wales “ha[d] been involved in this
case from the beginning,” that is, since August 2018, participating in 13 “of the 22
hearings held over the course of this case.” Ultimately, because “the only applicable
factor weigh[ed] in favor of the Native Village of Wales, and because deference should
be given to the Tribe in which the Indian child is a member,” the court designated Wales
as Trent’s tribe for ICWA purposes.
Wales, OCS, and Chignik Lagoon all disagree with the way the court
determined the child’s tribe. Wales argues that although the superior court properly
decided on Wales, “Wales is the only Tribe for which [Trent] meets the standard for
‘Indian child’ ” and the court therefore should have stopped its analysis at 25 C.F.R.

26
See 25 C.F.R. § 23.109(c)(2)(iv).
-12- 7628
§ 23.109(a). Wales argues that Trent does not meet the definition of Indian child by
virtue of his eligibility for membership in Chignik Lagoon because “to meet [the]
definition of Indian child under ICWA, it is not enough that Trent be eligible [for
membership in a tribe]. He must also have a biological parent who is [a] member of
Chignik Lagoon, which he certainly does not.”
OCS likewise agrees with the designation of Wales as Trent’s tribe, but it
argues that only 25 C.F.R. § 23.109(b) applies. OCS argues, “Because Trent is eligible
for membership in more than one tribe but is only enrolled in one, the court should have
applied subsection (b) and deferred to Wales as Trent’s Tribe.”
Finally, Chignik Lagoon argues that while the court properly proceeded to
subsection (c), it erred in finding that Wales had “more significant contacts” with Trent
than Chignik Lagoon did. Chignik Lagoon argues that in making this determination the
court mistakenly “focused on the interaction between Wales and the court, rather than
the interaction between the child and the Tribe.” Chignik Lagoon argues that “[t]he
record in this case is clear that the child had more significant contacts with Chignik
Lagoon” given that “the child was living in a Chignik Lagoon tribal home”; his foster
father’s “mother . . . is a Chignik Lagoon Tribal member . . . and sees the child
frequently”; his foster father’s cousin is a Chignik Lagoon member and “visits with the
child on a weekly basis”; and “[f]amily members from Chignik Lagoon visit [Trent’s
foster parents] and have contact with the child on a regular basis.” Chignik Lagoon
compares this contact to that of Wales, which it summarizes as follows: “[T]he mother
had one visit with the child in the child’s life,” “[t]he child had no contact with maternal
biological family members with one possible exception on one occasion,” and “Wales
never contacted the foster family.”
We do not reach the question of which tribe has more significant contacts
with Trent because we agree with Wales that it is the only tribe through which Trent

-13- 7628
meets the ICWA definition of “Indian child.” Again, “Indian child” is statutorily defined
as “any unmarried person who is under age eighteen and is either (a) a member of an
Indian tribe or (b) . . . eligible for membership in an Indian tribe and . . . the biological
child of a member of an Indian tribe[.]”27 Trent is a member of Wales and so meets the
definition in (a). As for (b), Trent is eligible for membership in Chignik Lagoon, but he
“is the biological child of a member of” Wales, not Chignik Lagoon. Whether Trent
meets the definition of “Indian child” under (b) therefore depends on whether the statute
requires that the “Indian tribe” in which the child is eligible for membership be the same
as the biological parent’s tribe. In other words, is (b) satisfied if the child is eligible for
membership in one tribe and the biological parent is a member of another?
We conclude that the subsection (b) definition, as reasonably interpreted,
contemplates a single tribe. The BIA regulations aid in interpreting the ICWA statutes,28
and they define “Indian child” similarly: “any unmarried person who is under age 18
and either: (1) [i]s a member or citizen of an Indian Tribe; or (2) [i]s eligible for
membership or citizenship in an Indian Tribe and is the biological child of a
member/citizen of an Indian Tribe.”29 The agency comments to this regulation indicate
both that the regulatory and statutory definitions are meant to be the same and that the
child would have to be eligible for membership in the same tribe as the parent in order
to meet the second “Indian child” definition:

27
25 U.S.C. § 1903(4).
28
See State, Dep’t of Health & Soc. Servs., Off. of Child.’s Servs. v. Cissy A.,
513 P.3d 999, 1009 (Alaska 2022) (considering BIA regulations as “add[ing] specificity
to [ICWA’s] expert witness requirement”).
29
25 C.F.R. § 23.2. The only substantive difference between the statute and
the BIA guideline is the addition of the allowance of citizenship to form the basis for
tribal affiliation.
-14- 7628
 The final rule reflects the statutory definition of “Indian
child,” which is based on the child’s political ties to a
federally recognized Indian Tribe, either by virtue of the
child’s own citizenship in the Tribe, or through a biological
parent’s citizenship and the child’s eligibility for citizenship.
Congress recognized that there may not have been an
opportunity for an infant or minor child to be enrolled in a
Tribe prior to the child-custody proceeding, but nonetheless
found that Congress had the power to act for those children’s
protection given the political tie to the Tribe through parental
citizenship and the child’s own eligibility.[30]
The BIA explained, “This is consistent with other contexts in which the citizenship of
a parent is relevant to the child’s political affiliation to that sovereign.”31
Other BIA comments reinforce this explanation:
Comment: A commenter noted that the regulations
sometimes refer to the Indian child being “a member or
eligible for membership” without specifying that if the child
is not a member, then the child’s parent must be a member
and the child must be eligible for membership.
Response: The statute specifies that if the child is not a
Tribal member, then the child must be a biological child of a
member and be eligible for membership, in order for the child
to be an “Indian child.” 25 U.S.C. 1903(4). The final rule
addresses this oversight by clarifying in each instance that the
biological parent must be a member in addition to the child
being eligible for membership.[32]

-15- 7628
 Case law from across the country, though not addressing this issue directly,
is consistent with an interpretation requiring that the child’s eligibility and the biological
parent’s membership involve the same tribe.33 We conclude that to meet the definition
of “Indian child” under 25 U.S.C.§ 1903(4)(b), the child must be eligible for membership
in the biological parent’s tribe, not a different tribe. Because neither of Trent’s biological
parents is a member of Chignik Lagoon, Trent does not meet the definition of “Indian
child” under subsection (b). His tribe for ICWA purposes is properly determined by his
status as a Wales tribal member.
C. Chignik Lagoon Does Not Have Standing To Challenge The Transfer
Of Post-Termination Proceedings To The Wales Tribal Court.
In addition to challenging the superior court’s ruling on Trent’s tribal
membership, Chignik Lagoon argues that the court erred by allowing Wales to intervene
and by ordering the transfer of jurisdiction to the Wales tribal court. We raised sua
sponte the issue of Chignik Lagoon’s continued standing to pursue these procedural
issues on appeal if we were to affirm the superior court’s finding that Wales, not Chignik
Lagoon, is Trent’s tribe for ICWA purposes. The parties submitted supplemental

briefing on the standing issue.34
“Standing is a ‘rule of judicial self-restraint based on the principle that
courts should not resolve abstract questions or issue advisory opinions.’ ”35 “[A] basic
requirement of standing is adversity of interests.”36 “A party satisfies the adversity
requirement when the party has ‘a “sufficient personal stake” in the outcome of the
controversy and “an interest which is adversely affected by the complained-of
conduct.” ’ ”37 Although in Alaska “standing restrictions are prudential, rather than
constitutionally mandated,”38 appellate courts have an “obligation to be sure that standing
exists and to raise, sua sponte if need be, any deficiency.”39
Chignik Lagoon argues that it has standing to challenge the superior court’s
transfer of post-termination proceedings to the Wales tribal court because Chignik
Lagoon was made a party to the proceedings when it intervened. It argues that even if

34
Chignik Lagoon argues that because the other parties did not appeal the
superior court’s grant of intervenor status, they waived or abandoned any argument that
its intervenor status does not convey standing on appeal. But the absence of objection
does not determine whether we are obliged to consider the arguments of a party that
lacks standing to raise them. See State v. Alaska Civ. Liberties Union, 978 P.2d 597, 614
n.106 (Alaska 1999).

it does not have standing on that basis alone, its interest in keeping Trent with his foster
family independently satisfies the requirements for interest-injury standing, a standing
doctrine which requires a party to have both “ ‘an interest adversely affected’ and ‘a
sufficiently personal stake in the controversy to guarantee adversity.’ ”40 Alternatively,
Chignik Lagoon argues that its attempts to enforce ICWA and the Adoption Assistance
and Child Welfare Act41 implicate parens patriae standing42 and that it has standing
based on the superior court’s alleged violation of its due process rights.43
We are not persuaded. Chignik Lagoon’s status as an intervenor is not
enough to establish standing for the duration of the case regardless of the disposition of

assert parens patriae interests, a tribe “must be able to articulate an injury to the well­
being of the [tribe] as a whole or to a sufficiently large segment of its population, and the
overall injury must be more than the mere sum of its parts.” Id.

Chignik Lagoon argues that the superior court denied it due process by
ordering the proceedings to be transferred to Wales’s tribal court “without any further

the issues in which it claims an interest.44 The superior court decided, and we affirm, that
Chignik Lagoon is not Trent’s tribe for ICWA purposes. The policies underlying ICWA
— “the protection and preservation of Indian tribes and their resources,” including
“Indian children” — apply both to tribes of which a child is a member and those for
which a child can claim eligibility.45 But we do not believe that ICWA’s policies are
intended to protect the interests of a tribe whose relationship to the child depends on
membership eligibility when neither parent is a member of the tribe and the child is a
member of another tribe.
We emphasize that our holding on this question is prudential and limited
to the facts of this case. Trent is a member of Wales and not of Chignik Lagoon; his
biological parents have no connection to Chignik Lagoon; his foster father did not
himself become a member of Chignik Lagoon until after the superior court had granted
the transfer of jurisdiction to the Wales tribal court. It would seem anomalous to us if
ICWA were interpreted as allowing one tribe to interfere in another tribe’s child
protective proceedings involving the second tribe’s own member child. We conclude
that Chignik Lagoon’s interests, whatever they may be, are not sufficient to satisfy the
adversity requirement.46

44
Analogously, we have questioned whether a parent “has standing to appeal
the trial court’s finding regarding placement after termination of [the parent’s] parental
rights.” Shirley M. v. State, Dep’t of Health & Soc. Servs., Off. of Child.’s Servs., 342
P.3d 1233, 1244 (Alaska 2015).
45
25 U.S.C. § 1901 (2)-(3).
46
Chignik Lagoon’s arguments that it has standing based on a parens patriae
interest in enforcing ICWA and the Adoption Assistance and Child Welfare Act and a
violation of its due process rights are likewise unconvincing. Because we do not find
that Chignik Lagoon has suffered an injury, parens patriae standing is inapplicable here.

 Because we conclude that Chignik Lagoon does not have standing to
challenge Wales’s intervention or the transfer of post-termination CINA proceedings to
the Wales tribal court, we do not reach the merits of those challenges.
V. CONCLUSION
We AFFIRM the superior court’s order recognizing Wales as Trent’s tribe
and REMAND to the superior court for further proceedings consistent with this opinion.

(...continued)
See supra note 42. Likewise, Chignik Lagoon did not suffer a violation of its due
process rights; the superior court allowed it to intervene and present evidence and
considered its objections to transfer on the merits.
