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, — U.S. -,
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
In Kerr I, we wrestled with the two essential Supreme Court cases on legislator standing, Coleman v. Miller,
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.
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,
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,
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

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,
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 legislative act that would have taken effect but for” the challenged constitutional provision. Arizona,
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 nulliffy]’ any vote by the Legislature, now or ‘in the future,’ purporting to adopt a redistricting plan.” Id. (quoting Raines,
In distinguishing Raines, the Court first noted that the case before it did “not touch or concern the question whether Congress
Ill
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
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 [mjembers 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.”
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,
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.”
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,
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,
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,
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,
Moreover, the vote authorizing the ami-cus 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,
The Arizona Legislature was permitted to challenge a state constitutional provision stripping that body of certain power because it was “an institutional plaintiff.” Arizona,
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,
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,

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,
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,
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 taken.” Jobin v. Boryla (In re M & L Business Mach. Co.),
For similar reasons, we decline to address the political question doctrine. See Kerr I,
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.
Notes
. We do not need to decide in this case whether a group of legislators large enough to prevail on a vote, see Coleman,
