LIPEZ, Circuit Judge.
Plaintiff Gregorio Igartúa,. a U.S. citizen-resident of Puerto Rico, returns to this court for the fifth time in search of a legal remedy for his claim that he has a constitutional right to vote in certain federal elections. Here, for the second time, Igar-túa and his fellow plaintiffs specifically challenge the denial of the right of Puerto Rico citizens to vote for representatives to the U.S. House of Representatives and their right to have five Puerto Rico representatives apportioned to that body. Plaintiffs also assert that the district court again erred in refusing to convene a three-judge court to adjudicate their claims.
When Igartúa first raised the issue of congressional representation in 2010, a panel majority disposed of the three-judge-court issue in a footnote. On the merits, it concluded that we were bound by past circuit decisions to find that “the Constitution does not permit granting such a right to the plaintiffs by means other than [151]*151those specified for achieving statehood or by amendment.” Igartúa v. United States (“Igartúa IV”). 626 F.3d 592, 594, 598 n.6 (1st Cir. 2010), en banc review denied, 654 F.3d 99 (1st Cir. 2011), cert. denied, — U.S. -, 132 S.Ct. 2376, 182 L.Ed.2d 1017 (2012). As we explain in Section I below, we again find ourselves bound by circuit precedent, and we thus must affirm the judgment of the district court refusing to convene a three-judge court and dismissing the case on the merits.
In so doing, however, we emphasize that we now doubt the correctness of thé brief, yet controlling, footnote in Igartúa IV rejecting the call for a three-judge court. See 626 F.3d at 598 n.6.1 Moreover, if our court were now to conclude, in an en banc proceeding, that a three-judge panel should have been convened to hear the constitutional claims addressed in Igartúa IV, the merits ruling in Igartúa IV would be void. See infra. Hence, though we as a panel must follow Igartúa IV, the three-judge-court issue is one of substantial importance that should be reconsidered by the full court in an en banc rehearing of this case.
I. The Instant Appeal
In all material respects, this action is a reprise of Igartúa IV. As the district court noted, “Plaintiffs’ arguments in the Complaint at bar are nearly identical to the ones raised in Igartúa IV.” Igartúa v. United States, 86 F.Supp.3d 50, 52 (D.P.R. 2015). In addition, the parties in the two cases largely overlap. Four of the six plaintiffs here were plaintiffs in Igartúa IV. The defendants in Igartúa IV were the President of the United States, the U.S. Secretary of Commerce, and the Clerk of the U.S. House of- Representatives—the same defendants as here.
The legal rulings made in Igartúa IV are thus binding on most of the parties in this action under principles of res judi-cata, see Haag v. United States, 589 F.3d 43, 45 (1st Cir. 2009), and, in any event, the doctrine of stare decisis bars us, as a panel, from reaching a different conclusion on the same questions of law, see United States v. González-Mercado, 402 F.3d 294, 299 (1st Cir. 2005) (“We have heard and rejected this argument before. Under the doctrine of stare decisis, then, the issue is foreclosed.” (citations omitted)); see also United States v. Mouscardy, 722 F.3d 68, 77 (1st Cir. 2013) (noting that an earlier panel decision binds a later panel under “[t]he law of the circuit doctrine”).
Hence, because we are not at.liberty to depart from the dispositive holdings in Igartúa IV, we must affirm the judgment of the district court granting defendants’ motion to dismiss.2 However, having close[152]*152ly examined the pertinent law, we are persuaded that a summary affirmance should not properly, or fairly, be the end of the case.
II, The Three-Judge-Court Requirement
Under 28 U.S.C. § 2284(a), “[a] district court of three judges shall be convened ... when an action is filed challenging the constitutionality of the apportionment of congressional districts.” Accordingly, when the district court judge originally assigned to a case determines that one or more of the plaintiffs claims warrants a three-judge court, the judge must take the steps necessary to convene a three-judge panel. See 28 U.S.C. § 2284(b); see also Shapiro v. McManus, — U.S. -, 136 S.Ct. 450, 454, 193 L.Ed.2d 279 (2015). The three-judge court’s ruling on the merits of such claims is appealable only to the U.S. Supreme Court. See 28 U.S.C. §§ 1253, 1291; Idlewild Bon Voyage Liquor Corp. v. Epstein, 370 U.S. 713, 715-16, 82 S.Ct. 1294, 8 L.Ed.2d 794 (1962). Hence, when a three-judge court is properly convened to hear claims within the scope of § 2284(a), the court of appeals does not play a role in resolving the merits. See Idlewild Bon Voyage Liquor Corp., 370 U.S. at 715-16, 82 S.Ct. 1294 (noting that a court of appeals is “precluded from reviewing on the merits a case which should have originally been determined by a court of three judges”).
If a case is brought improperly to the court of appeals—because the district court erroneously refused to convene a three-judge court—any subsequent merits ruling by the appellate panel is void. See Stratton v. St. Louis Sw. Ry. Co., 282 U.S. 10, 16, 51 S.Ct. 8, 75 L.Ed. 135 (1930) (“Nor does an appeal [on the merits] lie to the Circuit Court of Appeals from an order or decree thus entered by a District Judge without authority, for to sustain a review upon such an appeal would defeat the purpose of the statute by substituting a decree by a single judge and an appeal to the Circuit Court of Appeals for a decree by three judges and a direct appeal to th[e] [Supreme] Court.”).3
Thus, if a three-judge district court should have been convened to address the constitutional claims asserted in Igartúa IV, our rejection of Igartúa’s claims on the merits in that case would have no prece-dential force here. The three-judge-court question in Igartúa IV was therefore of great consequence—affecting our very authority to hear the case.4 Yet, the issue was decided with the following footnote:
[153]*153We also reject the argument made by Igartúa, but not made by the government, that this case must be heard by a three-judge district court under -28 U.S.C. § 2284(a). That statute provides that a “district court of three judges shall be convened when ... an action is filed challenging the constitutionality of the apportionment of congressional districts.” Id. That is not the issue in this case.
Igartúa IV, 626 F.3d at 598 n.6.5
This unelaborated assertion belies the complexity of Igartúa’s contention that he is entitled to have his claims heard by a three-judge district court. Moreover, there is reason to doubt the correctness of the footnote’s rejection of the applicability of § 2284(a). To demonstrate the need to revisit our cursory holding, we review below the issues that determine whether a three-judge court must be convened. We first consider whether § 2284(a) in fact' covers the type of claim raised by Igartúa and then examine the requirement of a “substantial federal question.” See Shapiro, 136 S.Ct. at 455.
A. Scope of the Three-Judge-Court Statute
The three-judge-court statute applies to a claim “challenging the constitutionality of the apportionment of congressional districts.” 28 U.S.C. § 2284(a) (emphasis added). As recounted above, in footnote 6 in Igartúa IV, we stated simply: “That is not the issue in this case.” We understand that cryptic comment to mean that the statute does not cover Igartúa’s claims because Igartúa challenges Congress’s failure to include Puerto Rico within its apportionment of districts instead of attacking a specific apportionment of districts. Supreme Court precedent, however, supports a broader view of the statute.
In 1998, Lois Adams and other residents of the District of Columbia filed a complaint in federal district court alleging that “Congress has unconstitutionally excluded them from apportionment to a congressional district,” in violation of Article IV’s Guarantee Clause6 and the Fourteenth Amendment. Adams v. Clinton, 26 F.Supp.2d 156, 157-58 (D.D.C. 1998). Adams and her co-plaintiffs requested that the case be heard by a three-judge district court under § 2284(a). Id. Over the objections of the defendants—including the President of the United States and officers of the U.S. House of Representatives—the district judge concluded that Adams’ no-napportionment claims were covered by § 2284(a) and asked the chief judge of the district to convene a three-judge district court to hear the case. Id. at 161.
In deciding the case, a majority of the three-judge panel noted that “[t]he parties have not asked us to revisit the original judge’s .determination that this case falls [154]*154within the confines of the three-judge court statute, and we will not do so insofar as the complaints allege the failure to apportion members of the House of Representatives to the District.” Adams v. Clinton, 90 F.Supp.2d 35, 38 (D.D.C. 2000) (three-judge court). The majority concluded that the plaintiffs had standing, bqt then went on to grant the defendants’ motions to dismiss on the merits.7 Id. at 45, 72.
Adams appealed the decision of the three-judge court directly to the Supreme Court, see 28 U.S.C. § 1253, insisting, inter alia, that the case was properly before a three-judge court under § 2284(a). See Jurisdictional Statement at *21-30, Adams v. Clinton, 531 U.S. 941 (2000) (No. 00-97), 2000 WL 33999989. In response, the government filed a “Motion to Dismiss or Affirm.” Motion to Dismiss or Affirm, Adams, 531 U.S. 941 (No. 00-97). In the opening paragraph of the Argument section of its motion, the government asked the Court to dismiss the appeal either because the “three-judge district court lacked jurisdiction over appellants’ claim” or because “appellants lack standing to seek the relief that they have requested from any federal court.” Id. at 9. In- the alternative, the government asked the Court to “affirm the judgment of the three-judge court because appellants’ constitutional claim lacks merit.” Id. (emphasis added).8
The Supreme Court affirmed the judgment of the three-judge district court without explanation. Adams v. Clinton, 531 U.S. 941, 121 S.Ct. 336, 148 L.Ed.2d 270 (2000) (“Judgment affirmed.”). The Court also noted that “Justice STEVENS would dismiss the appeal.” Id. Given the government’s arguments distinguishing between dismissal and affirmance, and Justice Stevens’ position that dismissal—rather than affirmance—was appropriate, the Court’s decision to affirm appears to signify a determination that the three-judge court was properly convened for Adams’ nonappor-tionment claim. Indeed, the Court has previously held that where a “three-judge court was ... improperly convened, ... this Court does not have jurisdiction to entertain a direct appeal from the judgment in such case.” Mobay Chem. Corp. v. [155]*155Costle, 439 U.S. 320, 321, 99 S.Ct. 644, 58 L.Ed.2d 549 (1979) (per curiam) (citation omitted).
Notably, the government itself adopted the view that the Supreme' Court had determined that Adams’ claim was properly brought under § 2284(a). After the 'Supreme Court décision, Adams returned to the three-judge court with a motion filed under Federal Rule of Civil Procedure 60(b) seeking reconsideration of her dismissed claims. The three-judge court denied the motion,9 and Adams appealed that denial to the D.C. Circuit. The D.C. Circuit dismissed the appeal for lack of jurisdiction, stating that the “appeal from the three-judge district court’s denial of relief ... is not properly taken to this court.” Adams v. Bush, No. 00-5239, 2001 WL 1488944, at *1 (D.C. Cir. 2001) (per cu-riam). Adams petitioned for a writ of cer-tiorari. In its brief in opposition, the government wrote:
In its motion to dismiss or affirm petitioners’ prior direct appeal, the-government argued that petitioners’ direct appeal should be dismissed because 28 U.S.C. 2284(a) did not give the district court jurisdiction over petitioners’ equal protection claim. Instead of dismissing , the appeal for lack of jurisdiction, however,. this Court affirmed the judgment of the three-judge court on the merits. That determination by this Court that the three-judge district court was properly convened under Section 2284(a) “settles the issue[ ] for the parties.”
Br. for the President of the United States in Opposition at 6 n.2, Adams v. Bush, 537 U.S. 812 (2002) (No. 01-1519) (alteration in original) (citation omitted) (quoting Mandel v. Bradley, 432 U.S. 173, 176, 97 S.Ct. 2238, 53 L.Ed.2d 199 (1977) (per curiam)).
In other words, the government interpreted the Supreme Court’s affirmance in Adams to mean that the nonapportionment claim was properly before the three-judge court and that the plaintiffs’ appeal of that panel’s decision was properly before the Supreme Court. The proceedings in Adams thus provide strong support for Igartúa’s argument that § 2284(a) covers a challenge to nonapportionment—in addition to claims of improper apportionment.
A ruling by the Supreme Court that Adams’ nonapportionment claim was properly addressed by a three-judge court cannot be disregarded as a nonprecedential “drive-by jurisdictional ruling.” Steel Co. v. Citizens for a Better Env’t, 523 U.S. 83, 91, 118 S.Ct. 1003, 140 L.Ed.2d 210 (1998). Such limited judgments occur when the jurisdictional issue “was neither challenged nor discussed in that case.” Lewis v. Carsey, 518 U.S. 343, 352 n.2, 116 S.Ct. 2174, 135 L,Ed.2d 606 (1996) (cited in Steel Co., 523 U.S. at 91, 118 S.Ct. 1003). As discussed above, the parties’- briefs fully addressed whether Adams’ nonapportionment claim was covered by the three-judge-court statute, and the government explicitly challenged the jurisdiction of the three-judge court and, in turn, that of the Supreme Court to hear the ease. See Motion to Dismiss or Affirm at 9-12, Adams, 531 U.S. 941 (No. 00-97).
Moreover, simply as a matter óf language, we see no reason to treat a claim that challenges the failure to apportion any congressional districts—entirely excluding a group of United States citizens from representation in Congress—differently [156]*156from a claim that challenges the allocation of too few congressional districts. As the single-judge district court in Adams reasoned, a challenge to nonapportionment is simply one type of apportionment challenge. See Adams, 26 F.Supp.2d at 161 (“These plaintiffs ... challenge their existing allocation of zero representatives.” (emphasis omitted)).
An inclusive construction of § 2284(a)’s language is also supported by the singular importance legislators attributed to apportionment claims when the Three-Judge Court Act was amended in 1976. A report by the Senate Judiciary Committee on the proposed amendment listed multiple reasons for eliminating the three-judge-court requirement for various types of claims. S. Rep. No. 94-204, at 3-4.10 Yet despite the goal to limit use of three-judge courts, the Report expressly endorsed retaining the procedure “for cases involving congressional reapportionment or the reapportionment of a statewide legislative body because ... these issues are of such importance that they ought to be heard by a three-judge court.” Id. at 9. A narrow reading of “apportionment” undermines the objective to retain the three-judge court procedure for these “importan[t]” claims.
Nor do we find an impediment to applying the three-judge-court statute to Igar-túa’s claims in the language that requires a challenge to “the constitutionality of the apportionment of congressional districts,” 28 U.S.C. § 2284(a) (emphasis added). Igartúa’s claim involves such a challenge. Members of this court have seen arguable merit, in particular, in Igartúa’s claim that the International Covenant on Civil and Political Rights (“ICCPR”)—which recognizes the right of “[ejvery citizen” to elect representatives—is a self-executing treaty that must be enforced, absent a constitutional prohibition, as “the supreme Law of the Land,” U.S. Const, art. VI, cl. 2. gee Igartúa IV, 626 F.3d at 608-11 (Lipez, J., concurring in the judgment); id. at 620-628 (Torruella, J., concurring in part and dissenting in part); see also Dist. Ct. Op. at 12-13 (advising the First Circuit to “reconsider its decision that Article 26 -of the ICCPR is a non-self-executing provision”). In other words, plaintiffs’ treaty-based claim is a constitutional claim that defendants have violated the Supremacy Clause of the Constitution by failing to comply with the United States’ obligation, under the ICCPR, to apportion congressional districts so as to provide all citizens with representation.
In sum, there is substantial merit in plaintiffs’ assertion that their claim to representation in the House of Representatives is within the scope of § 2284(a).
B. Substantiality
The Supreme Court has observed that, when deciding whether a three-judge court must be convened, “all the district judge must ‘determin[e]’ is whether the ‘request for three judges’ is made in a case covered by § 2284(a)—no more, no less.” Shapiro, 136 S.Ct. at 455 (quoting 28 U.S.C. § 2284(b)(1)) (alteration in original). The Court went on to explain, however, that this simple statement presumes subject-matter jurisdiction: “A three-judge court is not required where the district court itself lacks jurisdiction of the complaint or the complaint is not justiciable in the federal [157]*157courts.” Id. (alteration omitted) (quoting Gonzalez v. Automatic Emps. Credit Union, 419 U.S. 90, 100, 95 S.Ct. 289, 42 L.Ed.2d 249 (1974)).
In other words, ordinary subject matter jurisdiction requirements apply to the request for a three-judge court. An apportionment challenge falling within the terms of § 2284(a) will not require a three-judge court if the claim is “wholly insubstantial and frivolous” such that a federal court would lack subject matter jurisdiction to hear it. Id. (quoting Bell v. Hood, 327 U.S. 678, 682-83, 66 S.Ct. 773, 90 L.Ed. 939 (1946)); see also Vazza v. Campbell, 520 F.2d 848, 849 (1st Cir. 1975) (noting that we could affirm the dismissal of an action by a single-judge district court who had refused to request a three-judge court for a claim otherwise calling for one “only if appellant’s constitutional claims are ‘wholly insubstantial’ ” (quoting Goosby v. Osser, 409 U.S. 512, 512, 93 S.Ct. 854, 35 L.Ed.2d 36 (1973))). Thus, before convening a three-judge court, the district court must conclude that a plaintiffs claim presents “a substantial federal question.” Shapiro, 136 S.Ct. at 455.
The Supreme Court has made clear that this substantiality threshold is not a test of whether the allegations in the complaint state a claim for relief on the merits. Indeed, the Court expressly rejected the notion that, “where the ‘pleadings do not state a claim, then by definition they are insubstantial and so properly are subject to dismissal by the district court without convening a three-judge court.’ ” Shapiro, 136 S.Ct. at 455 (emphasis omitted) (quoting Duckworth v. State Admin. Bd. of Elec. Laws, 332 F.3d 769, 772-73 (4th Cir. 2003)). The Court described the failure-to-state-a-claim standard as “both too demanding and inconsistent with our precedents,” and it reiterated that “ ‘constitutional claims will not lightly be found insubstantial for purposes of the three-judge-court statute.” Id. (quoting Washington v. Confederated Tribes of Colville Reservation, 447 U.S. 134, 147-48, 100 S.Ct. 2069, 65 L.Ed.2d 10 (1980)). Hence, it is not enough for a claim to be without merit; rather, to fall short of the “substantial federal question” threshold, a claim must be “legally speaking non-existent” or “essentially fictitious.” Id. at 455-56 (quoting Bailey v. Patterson, 369 U.S. 31, 33, 82 S.Ct. 549, 7 L.Ed.2d 512 (1962) (per curiam)).
Although we did .not say so expressly, we had to have concluded in Igartúa IV that Igartúa’s claims meet the substantiality requirement for subject matter jurisdiction. There, we decided his claims on the merits, see 626 F.3d at 594-606, a step that we would not, and could not, have taken if those claims did not involve a substantial federal question. See Steel Co. v. Citizens for a Better Env’t, 523 U.S. 83, 94, 118 S.Ct. 1003, 140 L.Ed.2d 210 (1998) (“Without jurisdiction the court cannot proceed at all in any cause.” (quoting Ex parte McCardle, 7 Wall. 506, 514, 19 L.Ed. 264 (1868))).
Nor does our decision in Igartúa IV itself render the claims in this case insubstantial for the purpose of subject-matter jurisdiction. As explained above, if the district court and First Circuit panel were wrong about the applicability of § 2284(a)—and the case should have been heard in the first instance by a three-judge court—the prior panel’s merits decision would not stand and, hence, it could not create binding law.11
[158]*158The exclusion of the courts of appeals from the § 2284(a) scheme also helps to explain why the Supreme Court has indicated that only its own precedent can undermine a claim that otherwise would scale the statute’s subject-matter threshold. In Goosby, the Court held that one of its prior decisions did not render insubstantial an otherwise viable claim brought under the three-judge court statute, and thus a three-judge court was, required. See 409 U.S. at 518, 93 S.Ct. 854. In so finding, the Court stated that such a claim is insubstantial only if “its unsoundness so. clearly results from the previous decisions of this court as to foreclose the subject and leave no room for the inference that the questions sought to be raised can be the subject of controversy.” Id. (quoting Ex parte Poresky, 290 U.S. 30, 32, 54 S.Ct. 3, 78 L.Ed. 152 (1933)) (emphasis added); cf. Shapiro, 136 S.Ct. at 456 (concluding that a claim was substantial even though a plurality of the Court had found it nonjusticiable in a prior case; but a concurring justice supported the plaintiffs’ legal theory (discussing Vieth v. Jubelirer, 541 U.S. 267, 124 S.Ct. 1769, 158 L.Ed.2d 546 (2004))).
Within the context of the three-judge court scheme, the Court’s reference in Goosby to the preclusive effect of its own prior decisions must be understood as a limiting statement on the relevance of court of appeals precedent. In ordinary cases first involving appeals to the intermediate courts of appeals, the Supreme Court has the last word on issues of federal law when it chooses to hear a case. Under the three-judge-eourt framework, the Supreme Court provides the only level of appellate review. A fortiori, Goosby instructs, a claim cannot be rejected for lack of “a substantial federal question” unless “its unsoundness so clearly results from the previous decisions of [the Supreme Court].” Goosby, 409 U.S. at 518, 93 S.Ct. 854.12
Also, the Supreme Court’s summary af-firmance in Adams does not render Igar-túa’s claims insubstantial'. While the challenges in both Adams and here concern the nonapportionment of congressional districts for citizens residing outside the states, the District of Columbia and the Commonwealth of Puerto Rico are meaningfully distinct in both history and character.
Moreover, Adams did not address the implications of the ICCPR or “the view [159]*159that the Constitution does not necessarily forbid extensions of the rights it delineates.” Igartúa IV, 626 F.3d at 608 (Lipez, J., concurring in the judgment). The possibility that the Constitution, does not prohibit equal voting rights for Puerto Rico residents through congressional action was considered by two panel members in Igar-túa IV and has had academic recognition. See Igartúa IV, 626 F.3d at 616 (Torruella, J., concurring in part and dissenting in part) (“[WJhile the text of Section 2, Article I does not grant to citizens of Puerto Rico the right to vote for members of the House of Representatives, neither does it prohibit them that right, nor act as a limitation on the federal government’s authority to extend the franchise to territorial residents under other constitutional powers.”); id. at 608 (Lipez, J., concurring in the judgment) (“If the Constitution does not prohibit extending the right to vote to citizens who' reside outside ‘the several States,’ an enforceable treaty could provide the governing domestic law on that issue.”); José R. Coleman Tió, Six Puerto Rican Congressmen Go to Washington, 116 Yale L.J. 1389, 1394 (2007) (“Absent a clear constitutional intent to deny Congress the power to treat Puerto Rico as a state for purposes of representation in the House, the broad language of the Territorial Clause seems at least to provide a clearer source of power to enfranchise nonstate citizens than does the Seat of Government Clause [for D.C. residents].”). Hence, we think it plain that the Court’s view on the merits of a claim to congressional representation (with voting power) for citizens residing in Washington, D.C. does not dictate the outcome of the claim brought here by'citizens residing in the Commonwealth.
As noted above, the Supreme Court recently reaffirmed that we may not lightly reject constitutional claims brought under § 2284(a) as insubstantial based on a lack of subject-matter jurisdiction. See Shapiro, 136 S.Ct. at 455. Having necessarily concluded in Igartúa IV that at least some of plaintiffs’ claims “clear[ ] Goosby’s low bar” for substantiality, we see no basis for changing course now. Id. at 456. Accordingly, if § 2284(a) governs,, plaintiffs are entitled to a hearing before a three-judge court irrespective of our view as to the merits of those claims. See id. (“Perhaps petitioners will ultimately fail on the merits of their suit, but § 2284 entitles them to make their case before a three-judge district court.”).
III.
Appellant Igartúa has persisted in his pursuit of federal voting rights for the four million Puerto Rico residents who are United States citizens in the face of repeated rejection of his claims by this court. His objective is laudable. As one member of this panel emphasized in Igar-túa IV, “[n]o right is more precious in a free country than that of having a voice in the election of those who make the laws under which, as good citizens, we must live.” 626 F.3d at 638 (Torruella, J., concurring in part and dissenting in part) (quoting Wesberry v. Sanders, 376 U.S. 1, 17, 84 S.Ct. 526, 11 L.Ed.2d 481 (1964)); see also id. at 606 (“The unequal distribution of the fundamental privilege of voting among different categories of citizens is deeply troubling.” (Lipez, J., concurring in the judgment)).
In Igartúa IV, our court failed to appreciate the strength of plaintiffs’ argument that their constitutionally based apportionment claims should be heard by a three-judge court. As the Supreme Court has made clear, the ultimate merit of those claims is not the question. Rather, the need to convene a three-judge court turns on two issues: whether plaintiffs’ claims [160]*160are within the scope of § 2284(a) .and whether they satisfy the minimum requirements of substantiality for subject-matter jurisdiction.
Our analysis above demonstrates that these issues deserve considerably more deliberation than we have previously given them. Thus, with the benefit of hindsight and the Supreme Court’s renewed attention to the three-judge-court framework in Shapiro, we have come to believe that Igartúa’s request for a three-judge court should be addressed by our court en banc, “with the best advocacy available in support of all parties.” Igartúa IV, 626 F.3d at 612 (Lipez, J., concurring in the judgment). This is, inescapably, “a question of exceptional importance,” Fed. R. App. P. 35(a)(2), that “fits squarely within the guidelines for en banc review,” Igartúa IV, 626 F.3d at 612. Any request for such reconsideration should be granted without delay.
As a panel, however, bound by precedent, we must affirm the judgment of the district court.
So ordered.
