ON PETITION FOR REHEARING EN BANC

. Treating the Petition for Rehearing En Banc as a Petition for Panel Rehearing, the Petition for . Panel Rehearing is DENIED. The court having been polled at the request of one of the members of the court and a majority of the judges who are in.regular active service not having voted in favor (Fed. R. App. P. and 5th CiR. R. 35), The Petition for Rehearing En Banc is DENIED.

with whom É. GRADY JOLLY, EDITH H. JONES, RHESA HAWKINS BARKSDALE, EMILIO M. GARZA, EDITH BROWN CLEMENT and PICKERING, Circuit Judges, join, dissenting from the denial of rehearing en banc:

Because the panel majority has given insufficient attention to this court’s duty to enforce the Eleventh Amendment to the United States Constitution, I respectfully dissent. ‘ In the main, my reasons are the same as those that are cogently set forth in Judge Garza’s dissent, 318 F.3d at 417-21, in which he shows that “a challenge to the constitutionality of a statute underlying a [suit under Ex parte Young, 209 U.S. 123, 28 S.Ct. 441, 52 L.Ed. 714(1908),] is a proper subject of an Eleventh Amendment immunity analysis and that consideration *678of such a challenge is within the scope of an interlocutory appeal from the denial of a claim of Eleventh Amendment immunity,” id. at 421.

If a state is sued pursuant to an unconstitutional statute, the Eleventh Amendment grants it immunity from suit, not just immunity from ultimate liability. Logically, the constitutional question must be addressed on interlocutory appeal if that immunity is to be properly recognized.

This is the same methodology the Supreme Court has required in qualified immunity appeals. In Siegert v. Gilley, 500 U.S. 226, 111 S.Ct. 1789, 114 L.Ed.2d 277 (1991), the Court held that the first step in a determination of qualified immunity is whether there was a “violation of any constitutional right at all.” Id. at 233, 111 S.Ct. 1789. The Court emphasized that the immunity at issue was an “immunity from suit rather than a mere defense to liability.” Id. (citation and internal quotation marks omitted).

Immunity from suit applies equally in the Eleventh Amendment context. “One of the purposes of immunity, absolute or qualified, is to spare a defendant not only unwarranted liability, but unwarranted demands customarily imposed upon those defending a long drawn out lawsuit.” Id. The panel majority concluded not only that it is undesirable for a court to review the constitutional issue on interlocutory appeal, but that a court of appeals has no jurisdiction to do so. That decision is extreme and flies in the face of the undeniable logic of Siegeri and its progeny.

The Supreme Court has emphasized, as well, that “Eleventh Amendment immunity represents a real limitation on a federal court’s federal question jurisdiction.” Idaho v. Coeur d’Alene Tribe, 521 U.S. 261, 270, 117 S.Ct. 2028, 138 L.Ed.2d 438 (1997). At least to the extent that the issue is jurisdictional, it should be examined at the first available opportunity. Thus, in the panel majority’s jurisdictional analysis, its thrust should be not on the jurisdiction of a court of appeals to decide the constitutional question, but on whether the jurisdictional characteristics of Eleventh Amendment immunity require us to make the constitutional query on interlocutory appeal in order to give full, intended force to the amendment.

It may be argued, as does the panel majority, that the foregoing analysis is undermined by the language the panel majority relies on from Verizon Md., Inc. v. Pub. Serv. Comm’n, 535 U.S. 635, 122 S.Ct. 1753, 152 L.Ed.2d 871 (2002). Even if Verizon is to be read as the panel majority interprets it, that reading must be reconciled with the overriding concerns underlying our and the Supreme Court’s immunity methodology. Because the panel majority’s approach calls into question this court’s Eleventh Amendment immunity jurisprudence, the issue is enbancwor-thy, and the court’s failure to grant en banc review is error. I therefore respectfully dissent.
