    LUCERO, Circuit Judge.
    _________________________________
    We are asked to take a second look at this case to consider the effect of the
    Supreme Court’s intervening opinion in Arizona State Legislature v. Arizona
    Independent Redistricting Commission, 
    135 S. Ct. 2652
    (2015) (hereinafter
    “Arizona”). See Hickenlooper v. Kerr, 
    135 S. Ct. 2927
    (2015). In Arizona, the
    Supreme Court held that the Arizona Legislature as an institution had standing to
    challenge a voter-approved 
    proposition. 135 S. Ct. at 2659
    . For standing purposes,
    the Arizona Court distinguished individual legislators, cf. Raines v. Byrd, 
    521 U.S. 811
    (1997), from a legislature as a whole for claims challenging a legislature’s
    power. We conclude that this rule of law materially alters the jurisprudence on
    legislator standing and compels us to reverse course from our previous opinion in
    Kerr v. Hickenlooper, 
    744 F.3d 1156
    (10th Cir. 2014), vacated sub nom. 
    135 S. Ct. 2927
    (2015), (hereinafter “Kerr I”), in which we affirmed the district court’s ruling
    that individual legislators had standing. We now conclude that these individual
    6
    legislators lack standing because they assert only an institutional injury. We vacate
    the district court’s order and remand for further proceedings.
    I
    Plaintiffs are current and former government officials in Colorado, parents of
    school-aged children, and educators. They filed suit in the district court advancing
    several challenges to Article X, § 20 of the Colorado Constitution, commonly referred to
    as the Taxpayer’s Bill of Rights (“TABOR”). TABOR limits the revenue-raising power
    of state and local governments by requiring “voter approval in advance for . . . any new
    tax, tax rate increase, mill levy above that for the prior year, valuation for assessment
    ratio increase for a property class, or extension of an expiring tax, or a tax policy change
    directly causing a new tax revenue gain.” Colo. Const. art. X, § 20, cl. 4(a). The
    defendant, Governor John Hickenlooper, moved to dismiss the complaint. He argued that
    the plaintiffs lacked standing, that their claims presented nonjusticiable political
    questions, and that they failed to state a claim under the Equal Protection Clause.
    The district court granted in part and denied in part the Governor’s motion to
    dismiss. It dismissed plaintiffs’ equal protection claim, but concluded that certain
    plaintiffs, who were current state legislators (the “legislator-plaintiffs”), had standing and
    that their claims were not barred by the political question doctrine. The court declined to
    consider whether any other plaintiffs possessed standing. Upon motion by Governor
    Hickenlooper, the district court certified its order for interlocutory appeal under 28
    U.S.C. § 1292(b). We accepted jurisdiction and affirmed. Kerr 
    I, 744 F.3d at 1183
    .
    7
    In Kerr I, we wrestled with the two essential Supreme Court cases on legislator
    standing, Coleman v. Miller, 
    307 U.S. 433
    (1939), and Raines. In Coleman, the Court
    considered a challenge to Kansas’ ratification of a proposed constitutional amendment
    after the lieutenant governor cast a tie-breaking vote in the state 
    senate. 307 U.S. at 435
    .
    The Court held that twenty-one state senators, including the twenty who voted against
    ratification, possessed standing to sue because their “votes against ratification have been
    overridden and virtually held for naught although if they are right in their contentions
    their votes would have been sufficient to defeat ratification.” 
    Id. at 438.
    It concluded
    that “these senators have a plain, direct and adequate interest in maintaining the
    effectiveness of their votes.” 
    Id. In Raines,
    the Court considered whether the Line Item Veto Act (“LIVA”) caused
    cognizable injury by granting the President the authority to cancel certain spending and
    tax measures after signing them into 
    law. 521 U.S. at 814
    . The Court held that six
    members of Congress who voted against LIVA lacked standing to challenge the law. 
    Id. at 813-14.
    It distinguished Coleman on the ground that the legislators in that case had
    their votes “completely nullified.” 
    Id. at 823.
    In contrast, the Raines challengers merely
    alleged an “abstract dilution of institutional legislative power.” 
    Id. at 826.
    We acknowledged in Kerr I that neither Raines nor Coleman “maps perfectly onto
    the alleged injury in this case,” but concluded plaintiffs’ “allegations fall closer to the
    theory of vote nullification espoused in Coleman than to the abstract dilution theory
    rejected in Raines.” Kerr 
    I, 744 F.3d at 1165
    . The legislator-plaintiffs allege that
    TABOR deprives them of their ability to perform the “legislative core functions of
    8
    taxation and appropriation” and “remov[es] the taxing power of the General Assembly.”
    We determined that “[u]nder TABOR, a vote for a tax increase is completely ineffective
    because the end result of a successful legislative vote in favor of a tax increase is not a
    change in the law” and thus a legislator’s vote is “advisory from the moment it is cast.”
    
    Id. at 1165,
    1166.
    In making that determination, we considered several factors that distinguished this
    suit from Raines. In particular, we noted that legislator-plaintiffs lack a legislative
    remedy because “TABOR was not passed by, and cannot be repealed by, the Colorado
    General Assembly.” 
    Id. at 1166.
    But see 
    Raines, 521 U.S. at 824
    (noting that Congress
    could repeal LIVA by simple majority vote). Separation of powers concerns are not
    implicated because this case does not challenge an action taken by a coequal branch of
    the federal government. Kerr 
    I, 744 F.3d at 1168
    . But see 
    Raines, 521 U.S. at 819-20
    (“[O]ur standing inquiry has been especially rigorous when reaching the merits of the
    dispute would force us to decide whether an action taken by one of the other two
    branches of the Federal Government was unconstitutional.”). And although the General
    Assembly was not a party, it submitted an amicus brief in support of standing. Kerr 
    I, 744 F.3d at 1168
    . But see 
    Raines, 521 U.S. at 829
    (noting that both houses of Congress
    actively opposed the suit).
    We further noted several features of the alleged injury that counseled against
    standing. As in Raines, the legislator-plaintiffs did not “claim that they were ‘personally
    entitled’ to cast an effective vote on revenue-raising measures in the sense that the
    authority at issue runs . . . with the Member’s seat.” Kerr 
    I, 744 F.3d at 1170
    (quoting
    9
    
    Raines, 521 U.S. at 821
    ). But we determined that “this factor alone cannot be sufficient
    to defeat standing.” 
    Id. We also
    acknowledged but rejected the Governor’s argument
    that legislator-plaintiffs must identify a “specific legislative act,” 
    id. at 1168
    (quotation
    omitted), in order to establish standing because “[o]ur standing jurisprudence does not
    demand that plaintiffs engage in an obviously futile gesture,” 
    id. at 1170.
    And although
    we recognized that some cases have concluded individual legislators lack standing if their
    claimed injury impacted all members of a legislature equally, we noted that those cases
    rested in part on “the availability of internal legislative remedies, or separation-of-powers
    concerns, none of which are present in this case.” 
    Id. at 1171.
    Ultimately, we held that
    “the legislator-plaintiffs have sufficiently alleged an injury to the ‘plain, direct and
    adequate interest in maintaining the effectiveness of their votes.’” 
    Id. at1171 (quoting
    Coleman, 407 U.S. at 438
    ).
    II
    After we decided Kerr I, the Supreme Court handed down Arizona, which
    parallels the present action in many respects. In that suit, the Arizona Legislature
    argued that Proposition 106, which created an independent commission with sole
    authority over redistricting, violated the Elections Clause, U.S. Const. art. 1, § 4, cl.
    1. 
    Arizona, 135 S. Ct. at 2658-59
    . The Court held that the Legislature had standing,
    
    id. at 2665,
    but concluded that the regime did not violate the Elections Clause, 
    id. at 2677.
    The Arizona Court considered many of the same standing issues we confronted
    in Kerr I. It first held that the Legislature did not need to point to a “specific
    10
    legislative act that would have taken effect but for” the challenged constitutional
    provision. 
    Arizona, 135 S. Ct. at 2663
    (quotation omitted). It concluded that the suit
    was not “premature,” nor was the Legislature’s injury hypothetical, because any
    legislative act would “directly and immediately conflict with the regime Arizona’s
    Constitution establishes.” 
    Id. Under the
    Arizona Constitution, the Legislature does
    not have the power “‘to adopt any measure that supersedes [an initiative], in whole or
    in part, . . . unless the superseding measure furthers the purposes’ of the initiative.”
    
    Id. at 2664
    (quoting Ariz. Const. art. IV, pt. 1, § 1(14)). If the Legislature had
    adopted a redistricting plan, it would have violated the Arizona Constitution because
    any such adoption would constitute an attempt to supersede Proposition 106. 
    Id. Further, once
    the independent commission certifies its redistricting plan to the
    Secretary of State, the Arizona Constitution requires the Secretary to implement that
    plan and no other. 
    Id. (citing Ariz.
    Const. art. IV, pt. 2, § 1(17)). The Court held that
    “the Legislature need not violate the Arizona Constitution and show that the
    Secretary of State would similarly disregard the State’s fundamental instrument of
    government” to establish standing. 
    Id. The Court
    then considered Raines and Coleman. It concluded the
    Legislature’s asserted injury was similar to that alleged in Coleman. 
    Id. at 2665.
    As
    in Coleman, the Court reasoned, the Legislature had standing because Proposition
    106, in tandem with the Arizona Constitution’s prohibition on undermining the
    purposes of an initiative, would “‘completely nullif[y]’ any vote by the Legislature,
    11
    now or ‘in the future,’ purporting to adopt a redistricting plan.” 
    Id. (quoting Raines,
    521 U.S. at 823-24).
    In distinguishing Raines, the Court first noted that the case before it did “not
    touch or concern the question whether Congress has standing to bring a suit against
    the President,” which “would raise separation-of-powers concerns” and warrant an
    “‘especially rigorous’” standing inquiry. 
    Id. at 2665
    n.12 (quoting 
    Raines, 521 U.S. at 819
    ). The Court then described that its primary basis for refusing to extend Raines
    was the plaintiffs’ identity. The plaintiffs in Raines, who did not have standing, were
    “six individual Members of Congress” who failed to show an alleged injury that
    “zeroed in on any individual Member.” 
    Id. at 2664
    . Instead, the alleged injury was
    “‘widely dispersed’” and “‘necessarily impacted all Members of Congress and both
    Houses . . . equally.’” Id. (quoting 
    Raines, 521 U.S. at 821
    , 829) (alterations
    omitted). In contrast, the Legislature in Arizona had standing because it was “an
    institutional plaintiff asserting an institutional injury, and it commenced th[e] action
    after authorizing votes in both of its chambers.” 
    Id. Finally, the
    Court noted that
    Raines had “‘attached some importance to the fact that the Raines plaintiffs had not
    been authorized to represent their respective Houses of Congress.’” Id. (quoting
    
    Raines, 521 U.S. at 829
    ) (alterations omitted). In contrast, the Arizona Legislature as
    an institution brought the suit challenging Proposition 106 after “authorizing votes in
    both of its chambers.” 
    Id. III 12
          Adhering to the holding in Arizona, we conclude that a threshold question in
    the legislator standing inquiry is whether the legislator-plaintiffs assert an
    institutional injury. This issue was discussed briefly in Raines. 
    See 521 U.S. at 821
    (describing “the diminution of legislative power” as “a type of institutional injury”).
    But as we noted in Kerr I, both Raines and Coleman were brought by groups of
    individual legislators. See Kerr 
    I, 744 F.3d at 1170
    . Not so in Arizona. There, the
    Court was presented with “an institutional plaintiff asserting an institutional injury.”
    
    Arizona, 135 S. Ct. at 2664
    . Viewing these cases together, individual legislators may
    not support standing by alleging only an institutional injury.
    As defined in Arizona, institutional injuries are those that do not “zero[] in on
    any individual Member.” 
    Id. Instead, an
    institutional injury is “[w]idely dispersed”
    and “necessarily impact[s] all [m]embers of [a legislature] equally.” 
    Id. (quotation and
    alterations omitted). Thus, under Arizona, an institutional injury constitutes
    some injury to the power of the legislature as a whole rather than harm to an
    individual legislator. An individual legislator cannot “tenably claim a personal
    stake” in a suit based on such an institutional injury. 
    Id. (quotation omitted).
    This formulation differs in some respects from that expressed in Raines, which
    is internally inconsistent. The Raines Court described the injury alleged as a “type of
    institutional injury (the diminution of legislative power), which necessarily damages
    all Members of Congress and both Houses of Congress 
    equally.” 521 U.S. at 821
    . It
    also stated—consistent with Arizona—that the plaintiffs had “alleged no injury to
    themselves as individuals” and “the institutional injury they allege is wholly abstract
    13
    and widely 
    dispersed.” 521 U.S. at 829
    . But the Raines Court also stated that
    Coleman was “[t]he one case in which we have upheld standing for legislators . . .
    claiming an institutional injury.” 
    Id. at 821.
    Describing the injury in Coleman as “institutional” is difficult to square with
    the definition of an institutional injury provided in Arizona. As 
    discussed supra
    , the
    Coleman Court held that a group of legislators, whose votes would have been
    sufficient to defeat a proposed amendment if their position were correct, had “a plain,
    direct and adequate interest in maintaining the effectiveness of their 
    votes.” 307 U.S. at 438
    . Such a claim does not rest on an injury that “necessarily impacted all
    [m]embers of [a legislature] equally.” 
    Arizona, 135 S. Ct. at 2664
    (quotation and
    alterations omitted). To the contrary, Coleman considered which bloc of legislators
    had prevailed in a vote. Only the state senators whose votes were allegedly nullified
    suffered an injury; the twenty senators who voted in favor of the amendment at issue
    were not aggrieved at all. Thus, Coleman did not concern injury to the power of the
    legislature as a whole.
    Moreover, prior to characterizing Coleman as involving an institutional injury,
    the Raines Court declared that the plaintiffs’ “claim of standing is based on a loss of
    political power, not loss of any private right” and compared lower court decisions
    reaching different conclusions as to whether individual legislators have standing
    when they “assert injury to their institutional power as 
    legislators.” 521 U.S. at 820
    n.4. The Court also stressed that Powell v. McCormack, 
    395 U.S. 486
    (1969), which
    decided a case brought by an individual legislator who was denied a seat in the House
    14
    of Representatives, was inapposite. 
    Raines, 521 U.S. at 820-21
    . Thus, it may be that
    the Raines Court used the term “institutional” in describing Coleman to distinguish
    injuries that a legislator suffers in an official capacity from those suffered in a
    personal capacity.
    Whatever the meaning of this passage from Raines, however, we determine it
    clear that the Arizona Court used the term “institutional injury” to refer to a harm
    inflicted on a legislature itself, such that it necessarily impacts all members of that
    legislature in equal measure. 
    Arizona, 135 S. Ct. at 2664
    . And although we
    acknowledge that Arizona did not expressly hold that only an institutional plaintiff
    possesses standing to assert an institutional injury, that much is implicit in the
    Court’s opinion.1 If we misrepresent the present state of the pertinent jurisprudence,
    the Court itself can clarify the matter on further review.
    We accordingly consider whether the legislator-plaintiffs have alleged an
    institutional injury. They claim that TABOR deprives them of their ability to
    perform the “legislative core functions of taxation and appropriation.” Kerr 
    I, 744 F.3d at 1163
    . This injury shares several features with the one alleged in Arizona.
    The injury goes “well beyond mere abstract dilution.” Kerr 
    I, 744 F.3d at 1165
    (quotation omitted), cf. 
    Arizona, 135 S. Ct. at 2665
    . Additionally, TABOR, like
    Proposition 106, cannot be repealed “pursuant to the normal legislative process.”
    Kerr 
    I, 744 F.3d at 1166
    (quotation omitted); cf. 
    Arizona, 135 S. Ct. at 2664
    . And
    1
    We do not need to decide in this case whether a group of legislators large
    enough to prevail on a vote, see 
    Coleman, 307 U.S. at 438
    , would possess standing
    based upon an institutional injury.
    15
    neither case presents separation of powers concerns. Kerr 
    I, 744 F.3d at 1168
    ; cf.
    
    Arizona, 135 S. Ct. at 2665
    n.12. And most importantly, as in Arizona, the injury
    alleged by the legislator-plaintiffs is an institutional injury: it is based on the loss of
    legislative power that necessarily impacts all members of the General Assembly
    equally.
    In determining whether a party may rely on an institutional injury to
    demonstrate standing, the Court has considered whether the plaintiffs represent their
    legislative body as an institution. See 
    Arizona, 135 S. Ct. at 2664
    ; 
    Raines, 521 U.S. at 829
    . In Arizona, the Legislature “commenced th[e] action after authorizing votes
    in both of its 
    chambers.” 135 S. Ct. at 2664
    . In contrast, the Raines plaintiffs had
    “not been authorized to represent their respective Houses of 
    Congress.” 521 U.S. at 829
    . Similarly, when this suit was filed, only five of one hundred General Assembly
    members were parties. The Governor states that only three plaintiffs remain current
    members. And the plaintiffs have acknowledged that including their official
    positions in the complaint did not imply authority to represent the General Assembly.
    Thus, the legislator-plaintiffs pursue this action in their individual capacities, rather
    than as representatives for the General Assembly as a whole.
    An amicus brief from the General Assembly in support of legislator standing
    does not alter our analysis. An amicus is not a party. See Coal. of Ariz./N.M. Ctys.
    for Stable Econ. Growth v. Dep’t of Interior, 
    100 F.3d 837
    , 844 (10th Cir. 1996).
    And the amicus brief does not indicate institutional endorsement of the merits of the
    legislator-plaintiffs’ claims. The Senate Resolution approving the filing stated that
    16
    “[t]he involvement of the General Assembly as amicus curiae on the limited issue of
    standing . . . should carry no implication about the views of the General Assembly on
    the merits of such lawsuits.” S. Joint Res. 16, 69th General Assembly, 1st Regular
    Sess., at 2 (Colo. 2013).
    Moreover, the vote authorizing the amicus brief occurred two years after this
    suit was filed, and thus would not demonstrate that the “party invoking federal
    jurisdiction had the requisite stake in the outcome when the suit was filed.” Davis v.
    Fed. Election Comm’n, 
    554 U.S. 724
    , 734 (2008). We further note that 44 current
    General Assembly members, including a majority of the Colorado State Senate, filed
    an amicus brief supporting the Governor after the Supreme Court vacated our prior
    opinion. But we do not need to consider the relative weight of these filings in our
    standing analysis. We observe only that an amicus brief in support of standing does
    not constitute authorization to bring the suit on behalf of the institution. And because
    the legislator-plaintiffs are not authorized to represent the General Assembly or either
    chamber, they do not qualify as institutional plaintiffs.
    The Arizona Legislature was permitted to challenge a state constitutional
    provision stripping that body of certain power because it was “an institutional
    plaintiff.” 
    Arizona, 135 S. Ct. at 2664
    . But the legislator-plaintiffs are a group of
    individual members of the General Assembly with numbers too small to authorize
    this lawsuit or to enact a specific legislative act. The alleged injury “scarcely
    zeroe[s] in on any individual [m]ember.” 
    Id. “None of
    the plaintiffs, therefore, c[an]
    tenably claim a personal stake in the suit.” 
    Id. (quotation omitted).
    17
    In so holding, we do not suggest that an individual legislator can never bring
    suit. An individual legislator certainly retains the ability to bring a suit to redress a
    personal injury, as opposed to an institutional injury. For example, if a particular
    subset of legislators was barred from exercising their right to vote on bills, such an
    injury would likely be sufficient to establish a personal injury. See 
    Raines, 521 U.S. at 824
    n.7 (discussing similar hypotheticals). Under those circumstances, the
    legislator could claim a personal injury that zeroes in on the individual and is thus
    concrete and particularized. See 
    Powell, 395 U.S. at 550
    (action brought by
    individual claiming personal right to seat in the House of Representatives was
    justiciable). But the legislator-plaintiffs allege a different sort of injury altogether.
    They claim that they have been individually disempowered only concomitantly as a
    result of TABOR’s diminution of the General Assembly’s authority as an institution.
    In determining that the legislator-plaintiffs had standing, Kerr I rested on a
    number of factors identified in Coleman and Raines, including the availability of a
    legislative remedy, Kerr 
    I, 744 F.3d at 1166
    ; the existence of separation of powers
    concerns, 
    id. at 1168
    ; and the extent to which TABOR disempowered the legislator-
    plaintiffs, 
    id. at 1165-66.
    But Arizona materially altered the law on legislator
    standing such that the nature of the injury—whether it is personal or institutional—is
    a primary consideration in determining whether individual legislators may bring suit.
    Under Arizona, the legislator-plaintiffs assert only an institutional injury, and thus
    lack standing to bring this action.

    We previously emphasized the limited nature of this interlocutory appeal:
    “The district court determined that the plaintiffs who are current state legislators . . .
    have standing and thus declined to assess the standing of any other named
    plaintiffs . . . . We similarly limit our review to the standing of the legislator-
    plaintiffs.” Kerr 
    I, 744 F.3d at 1163
    . Governor Hickenlooper asks us to extend our
    review to determine whether any non-legislator plaintiffs have standing. We again
    decline to do so.
    The Governor argues that we are obligated to reach all jurisdictional questions
    in this interlocutory appeal. But our court frequently remands jurisdictional issues
    for determination by the district court. See, e.g., Dutcher v. Matheson, 
    733 F.3d 980
    ,
    990 (10th Cir. 2013) (remanding “with instructions for the district court to determine
    whether it has jurisdiction”); Motive Parts Warehouse v. Facet Enters., 
    774 F.2d 380
    ,
    389 (10th Cir. 1985) (“[W]e deem it more appropriate to have the trial court
    specifically address the standing issue on remand.”). Appellate courts have
    “discretion to remand issues, even jurisdictional ones, to the trial court when that
    court has not had the opportunity to consider the issue in the first instance.” Salmon
    Spawning & Recovery All. v. U.S. Customs & Border Prot., 
    550 F.3d 1121
    , 1134
    (Fed. Cir. 2008) (collecting cases).
    Declining to reach the issue of standing as to the remaining plaintiffs is
    particularly appropriate in the context of this interlocutory appeal. Although “[o]ur
    jurisdiction under 28 U.S.C. § 1292(b) is not confined to the question certified for
    appeal,” we “are limited to consideration of the order from which [the] appeal is
    19
    taken.” Jobin v. Boryla (In re M&L Business Mach Co.), 
    75 F.3d 586
    , 589 n.4 (10th
    Cir. 1996). Because the district court did not reach the Governor’s arguments as to
    the non-legislator plaintiffs in its certified order, we lack information about the other
    plaintiffs. We remand for the district court to make the initial determination
    regarding non-legislator plaintiffs’ standing.
    For similar reasons, we decline to address the political question doctrine. See
    Kerr 
    I, 744 F.3d at 1181
    . Because the district court erred in holding the legislator-
    plaintiffs possess standing, we vacate its certified order. On remand, if the district
    court concludes the remaining plaintiffs lack standing, there will be no reason to
    consider the political question doctrine. See Tenet v. Doe, 
    544 U.S. 1
    , 6 n.4 (2005)
    (federal courts possess discretion “to choose among threshold grounds for denying
    audience to a case on the merits” (quotation omitted)). If, however, the district court
    holds that some other plaintiffs possess standing, the district court may then consider
    other justiciability hurdles. In the interest of judicial economy, we conclude that a
    remand for consideration of non-legislator standing is the best course.
    V
    Because the legislator-plaintiffs rely on an institutional injury, we hold that
    they lack standing. We VACATE the district court’s certified order and REMAND
    for a determination of whether the non-legislator plaintiffs possess standing.
