specially concurring:
I concur in the denial of rehearing en banc in this case because any further action by our court, or the district court, would be improper, as I explain below.
An axiom in the study of law is that “hard facts make bad law.” The tragic events that have afflicted Mrs. Schiavo and that have been compounded by the resulting passionate inter-family struggle and media focus certainly qualify as “hard facts.” And, while the members of her family and the members of Congress have acted in a way that is both fervent and sincere, the time has come for dispassionate discharge of duty.
A popular epithet directed by some members of society, including some members of Congress, toward the judiciary involves the denunciation of “activist judges.” Generally, the definition of an “activist judge” is one who decides the outcome of a controversy before him or her according to personal conviction, even one sincerely held, as opposed to the dictates of the law as constrained by legal precedent and, ultimately, our Constitution. In resolving the Schiavo controversy it is my judgment that, despite sincere and altruistic motivation, the legislative and executive branches of our government have acted in a manner demonstrably at odds with our Founding Fathers’ blueprint for the governance of a free people — our Constitution. Since I have sworn, as have they, to uphold and defend that Covenant, I must respectfully concur in the denial of the request for rehearing en banc. I conclude that Pub.L.109-3 (“the Act”) is unconstitutional and, therefore, this court and the district court are without jurisdiction in this case1 under that special Act and should refuse to exercise any jurisdiction that we may otherwise have in this case. Under the first amended complaint in this case (the initial complaint was improperly grounded on habeas corpus) a basis for jurisdiction was Pub.L. 109-3.2 The second amended complaint adopted other, independent grounds for jurisdiction, including the Americans With Disabilities Act (“ADA”), The Civil Rights Act (42 *1272U.S.C. § 1983) and The Rehabilitation Act of 1973. We have held that the Rooker-Feldman3 doctrine is jurisdictional. Clearly, application of that doctrine should have been made in this case, the effect of which would have been to decline to exercise any jurisdiction that we or the district court did have under the ADA, the Civil Rights Act or the Rehabilitation Act of 1973.
Since the passage of Pub.L. 109-3 on the morning of March 21, 2005, its constitutionality has been presumed. See Schiavo ex. rel. Schindler v. Schiavo, 357 F.Supp.2d 1378, 1382, 2005 WL 641710, at *1 (M.D.Fla.2005); Schiavo ex rel. Schindler v. Schiavo, No. 05-11556, 2005 WL 648897, at *1, 403 F.3d 1223, 1225 (11th Cir. March 23, 2005). In the instant appeal, our court and the district court continue to indulge this presumption and decline to address the constitutionality of the law which purports to grant federal jurisdiction. See Schiavo ex. rel. Schindler v. Schiavo, No. 05-11628, 2005 WL 681652, 403 F.3d 1289 (11th Cir. March 25, 2005). Jurisdiction, however, is a prerequisite to the legitimate exercise of judicial power, and therefore we may not hypothetically assume jurisdiction to avoid resolving hard jurisdictional questions. See Steel Co. v. Citizens for a Better Env’t, 523 U.S. 83, 93-94, 118 S.Ct. 1003, 1012, 140 L.Ed.2d 210 (1998); Ex Parte McCardle, 74 U.S. (7 Wall.) 506, 514, 19 L.Ed. 264 (1869) (“Without jurisdiction the court cannot proceed at all in any cause.”). I write separately to explain how various provisions of Pub.L. 109-3 are an unconstitutional infringement on the core principles of separation of powers and how this dynamic nullifies the exercise of federal jurisdiction in this case.
A. Pub.L. 109-3 and the Separation of Powers
It is axiomatic that the Framers established a constitutional design based on the principles of separation of powers. See Marbury v. Madison, 5 U.S. (1 Cranch) 137, 176, 2 L.Ed. 60 (1803) (noting that separation of powers is one of the governmental principles “on which the whole American fabric has been erected”). The Framers established three coequal but separate branches of government, each with the ability to exercise checks and balances on the two others. And to pre*1273serve this dynamic, the “Constitution mandates that ‘each of the three general departments of government [must remain] entirely free from the control or coercive influence, direct or indirect, of either of the others.’ ” Mistretta v. United States, 488 U.S. 361, 380, 109 S.Ct. 647, 659, 102 L.Ed.2d 714 (1989) (quoting Humphrey’s Executor v. United States, 295 U.S. 602, 629, 55 S.Ct. 869, 874, 79 L.Ed. 1611 (1935)). Because of the important constitutional role assigned to the judiciary by the Framers in safeguarding the Constitution and the rights of individuals, see Federalist No. 78 (A. Hamilton), the execution of this constitutional mandate is particularly important when legislative acts encroach upon the independence of the judiciary. See INS v. Chadha, 462 U.S. 919, 961, 103 S.Ct. 2764, 2789, 77 L.Ed.2d 317 (1983) (Powell, J. concurring) (citing Federalist No. 48 for the proposition that the Framers enshrined in the Constitution separation of powers principles because of past legislative interference with the judiciary); Northern Pipeline Co. v. Marathon Pipe Line Co., 458 U.S. 50, 60, 102 S.Ct. 2858, 2866, 73 L.Ed.2d 598 (1982) (“[T]he independence of the judiciary [must] be jealously guarded.”). Accordingly, we risk imperiling our constitutional design if we do not inquire as to whether Pub.L. 109-3 infringes on the independence of the judiciary guaranteed by Article III of the United States Constitution.
Article III provides that the “judicial Power of the United States, shall be vested in one supreme Court, and in such inferior Courts as the Congress may from time to time ordain and establish.” U.S. Const, art. Ill, § 1. In defining the extent of federal judicial power, Article III provides that “judicial Power shall extend to all Cases, in Law and Equity, arising under this Constitution, the Laws of the United States, and Treaties made, or which shall be made, under their Authority” and to certain other enumerated cases and controversies. Id. at § 2. These provisions have led courts to the unremarkable conclusion that “[f]ederal courts are courts of limited jurisdiction” and may only exercise jurisdiction allowed under the Constitution when “authorized by ... statute.” Kokkonen v. Guardian Life Ins. Co. of Am., 511 U.S. 375, 377, 114 S.Ct. 1673, 1675, 128 L.Ed.2d 391 (1994). Consistent with this dynamic outlined by Article III, and pursuant to its Article I powers, see U.S. Const, art. I, § 8, the United States Congress has vested federal courts with original jurisdiction to hear claims “arising under the Constitution, laws, or treaties of the United States,” 28 U.S.C. § 1331, and claims in which certain amount in controversy and diversity of citizenship criteria are met, see 28 U.S.C. § 1332.
Against these most elementary of constitutional principles, Section 1 of Pub.L. 109-3 — which states that the United States District Court for the Middle District of Florida shall have jurisdiction to hear a suit regarding alleged violations of rights held by Mrs. Schiavo “under the Constitution or laws of the United States” — is not facially unconstitutional. If the Act only provided for jurisdiction consistent with Article III and 28 U.S.C. § 1331, the Act would not be in violation of the principles of separation of powers. The Act, however, goes further. Section 2 of the Act provides that the district court: (1) shall engage in “de novo” review of Mrs. Schiavo’s constitutional and federal claims; (2) shall not consider whether these claims were previously “raised, considered, or decided in State court proceedings”; (3) shall not engage in “abstention in favor of State court proceedings”; and (4) shall not decide the case on the basis of “whether remedies available in the State courts have been exhausted.” Pub.L. 109-3, § 2. Because these provisions constitute legislative dictation of how a federal court should exercise its judicial functions *1274(known as a “rule of decision”), the Act invades the province of the judiciary and violates the separation of powers principle.
An act of Congress violates separation of powers if it requires federal courts to exercise their Article III power “in a manner repugnant to the text, structure, and traditions of Article III.” Plaut v. Spendthrift Farm, Inc., 514 U.S. 211, 218, 115 S.Ct. 1447, 1452, 131 L.Ed.2d 328 (1995). By setting a particular standard of review in the district court, Section 2 of the Act purports to direct a federal court in an area traditionally left to the federal court to decide. See Fla. Progress Corp. v. Comm’r, 348 F.3d 954, 959 (11th Cir.2003) (noting that the standard of review is for the court to determine). In fact, the establishment of a standard of review often dictates the rule of decision in a case, which is beyond Congress’s constitutional power. See United States v. Klein, 80 U.S. (13 Wall.) 128, 146, 20 L.Ed. 519 (1871) (noting that Congress may not prescribe a “rule of decision” for a particular case). In addition, “the separation-of-powers doctrine requires that a branch not impair another in the performance of its constitutional duties.” Loving v. United States, 517 U.S. 748, 757, 116 S.Ct. 1737, 1743, 135 L.Ed.2d 36 (1996). By denying federal courts the ability to exercise abstention or inquire as to exhaustion or waiver under State law, the Act robs federal courts of judicial doctrines long-established for the conduct of prudential deci-sionmaking. See Ungaro-Benages v. Dresdner Bank AG, 379 F.3d 1227, 1237 n. 13 (11th Cir.2004) (describing abstention as a “prudential” doctrine); Duncan v. Walker, 533 U.S. 167, 178-79, 121 S.Ct. 2120, 2127-28, 150 L.Ed.2d 251 (2001) (discussing the jurisprudential merits of State remedy exhaustion doctrines); Labat v. Bennett, 365 F.2d 698, 707 (5th Cir.1966) (discussing courts’ use of the doctrine of waiver). In short, certain provisions of Section 2 of the Act attempt to “ ‘direct[ ] what particular steps shall be taken in the progress of a judicial inquiry,’ ” Plaut, 514 U.S. at 225, 115 S.Ct. at 1456 (quoting Thomas Cooley, ConstitutioNal Limitations 94-95). Because this is violative of the fundamental principles of separation of powers enshrined in our Constitution, they are unconstitutional. See Plaut, 514 U.S. at 240, 115 S.Ct. at 1463 (finding unconstitutional a congressional act which impinged on the independence of the judiciary by requiring federal courts to reopen federal judgments); Klein, 80 U.S. at 147 (invalidating legislation because “it passed the limit which separates the legislative from the judicial power” by dictating a rule of decision in a pending case).4 Mani*1275festly, because the Act applies to only this case5 it lacks the generality and pros-pectivity of legislation that comports with the basic tenets of the separation of powers.
In sum, while Congress may grant jurisdiction to a federal court consistent with Article III as it did in Section 1 of the Act,6 it may not “assume[ ] a function that more properly is entrusted to” the judiciary. See INS, 462 U.S. at 963, 103 S.Ct. at 2790 (Powell, J., concurring). By arrogating vital judicial functions to itself in the passage of the provisions of Section 2 of the Act, Congress violated core constitutional separation principles, it prescribed a “rule of decision” and acted unconstitutionally.
B. Pub.L. 109-3 and Severability
Recognizing that the provisions of Section 2 of the Act are unconstitutional, it remains to be determined whether such unconstitutionality renders the entire Act a nullity under the doctrine of nonsevera-bility. “The standard for determining the severability of an unconstitutional provision is well established: Unless it is evident that the Legislature would not have enacted those provisions which are within its power, independently of that which is not, the invalid part may be dropped if what is left is fully operative as a law.” New York v. United States, 505 U.S. 144, 186, 112 S.Ct. 2408, 2434, 120 L.Ed.2d 120 (1992) (internal quotations and citations omitted). In most cases where unconstitutional sections of a statute have been severed the legislation has contained a sever-ability clause. See, e.g., INS, 462 U.S. at 932, 103 S.Ct. at 2774. The absence of a severability provision, however, should not be construed to create a presumption against severability. See New York, 505 U.S. at 186, 112 S.Ct. at 2434.
While the haste in which the Act was passed offered little time for the full development of congressional findings, a comprehensive review of the available legislative history surrounding the passage of the Act reveals that Congress manifestly would not have passed an act which allowed federal courts to give deference to State court findings or exercise its discretion to invoke abstention or exhaustion doctrines. See 151 Cong. Rec. H1731 (daily ed. Mar. 20, 2005) (statements of Speaker Hastert (R-Ill.)) (referencing the availability of de novo review by noting that he supported the Act because it would allow the “case [to be] tried anew where the judge can reevaluate and reassess [Mrs. Schiavo’s] medical condition”); id. (statements of Rep. Stupak (D-Mieh.)) (referencing the availability of the doctrines of State court waiver, abstention, and exhaustion by noting that the Act allows a federal judge to review the case “without being prejudiced by any of the information from the Florida State case”). Had this been their intent, a federal court could have frustrated their purpose to obtain a stay of the State court order. See 151 Cong. Rec. S3100 (daily ed. Mar. 20, 2005) (statements of Majority Leader Frist (R-Tenn.)) (noting that in passing the leg*1276islation he “assume[d] ... the Federal court would grant a stay based on the facts of this case because Mrs. Schiavo would need to be alive in order for the court to make its determination”). The United States Supreme Court has stated that the most “relevant inquiry in evaluating sever-ability is whether the statute will function in a manner consistent with the intent of Congress.” Alaska Airlines, Inc. v. Brock, 480 U.S. 678, 107 S.Ct. 1476, 1480, 94 L.Ed.2d 661 (1987). Here, in the absence of Section 2, a federal court could nullify congressional intent, and therefore the Act is not subject to severability. As such, the constitutional infirmity of Section 2 of the Act renders the entire Act a nullity. Thus, under the Act and the Rooker-Feldman doctrine, the district court lacked a jurisdictional basis to render its decision and we lack jurisdiction on appeal.
C. Conclusion
The separation of powers implicit in our constitutional design was created “to assure, as nearly as possible, that each branch of government would confíne itself to its assigned responsibility.” INS, 462 U.S. at 951, 103 S.Ct. at 2784. But when the fervor of political passions moves the Executive and the Legislative branches to act in ways inimical to basic constitutional principles, it is the duty of the judiciary to intervene. If sacrifices to the independence of the judiciary are permitted today, precedent is established for the constitutional transgressions of tomorrow. See New York, 505 U.S. at 187, 112 S.Ct. at 2434. Accordingly, we must conscientiously guard the independence of our judiciary and safeguard the Constitution, even in the face of the unfathomable human tragedy that has befallen Mrs. Schiavo and her family and the recent events related to her plight which have troubled the consciences of many. Realizing this duty, I conclude that Pub.L. 109-3 is an unconstitutional infringement on core tenets underlying our constitutional system. Had Congress or the Florida legislature, in their legislative capacities, been able to constitutionally amend applicable law, we would have been constrained to apply that law. See Robertson v. Seattle Audubon Soc’y, 503 U.S. 429, 441, 112 S.Ct. 1407, 1414, 118 L.Ed.2d 73 (1992). By opting to pass Pub.L. 109-3 instead, however, Congress chose to overstep constitutional boündaries into the province of the judiciary. Such an Act cannot be countenanced. Moreover, we are bound by the Rooker-Feldman doctrine not to exercise any other jurisdictional bases to override a final state judgment. Should the citizens of Florida determine that its law should be changed, it should be done legislatively. Were the courts to change the law, as the petitioners and Congress invite us to do, an “activist judge” criticism would be valid.
APPENDIX
109th CONGRESS
1st Session
S. 686
For the relief of the parents of Theresa Marie Schiavo.
IN THE SENATE OF THE UNITED STATES
March 20, 2005
Mr. Frist (for himself, Mr. Martinez, and Mr. Santorum) introduced the following bill; which was read twice, considered, read the third time, and passed
AN ACT
For the relief of the parents of Theresa Marie Schiavo.
Be it enacted by the Senate and House of Representatives of the United States of America in Congress assembled,
*1277SECTION 1. RELIEF OF THE PARENTS OF THERESA MARIE SCHIA-VO.
The United States District Court for the Middle District of Florida shall have jurisdiction to hear, determine, and render judgment on a suit or claim by or on behalf of Theresa Marie Schiavo for the alleged violation of any right of Theresa Marie Schiavo under the Constitution or laws of the United States relating to the withholding or withdrawal of food, fluids, or medical treatment necessary to sustain her life.
SEC. 2. PROCEDURE.
Any parent of Theresa Marie Schiavo shall have standing to bring a suit under this Act. The suit may be brought against any other person who was a party to State court proceedings relating to the withholding or withdrawal of food, fluids, or medical treatment necessary to sustain the life of Theresa Marie Schiavo, or who may act pursuant to a State court order authorizing or directing the withholding or withdrawal of food, fluids, or medical treatment necessary to sustain her life. In such a suit, the District Court shall determine de novo any claim of a violation of any right of Theresa Marie Schiavo within the scope of this Act, notwithstanding any prior State court determination and regardless of whether such a claim has previously been raised, considered, or decided in State court proceedings. The District Court shall entertain and determine the suit without any delay or abstention in favor of State court proceedings, and regardless of whether remedies available in the State courts have been exhausted.
SEC. 3. RELIEF.
After a determination of the merits of a suit brought under this Act, the District Court shall issue such declaratory and in-junctive relief as may be necessary to protect the rights of Theresa Marie Schiavo under the Constitution and laws of the United States relating to the withholding or withdrawal of food, fluids, or medical treatment necessary to sustain her life.
SEC. 4. TIME FOR FILING.
Notwithstanding any other time limitation, any suit or claim under this Act shall be timely if filed within 30 days after the date of enactment of this Act.
SEC. 5. NO CHANGE OF SUBSTANTIVE RIGHTS.
Nothing in this Act shall be construed to create substantive rights not otherwise secured by the Constitution and laws of the United States or of the several States.
SEC. 6. NO EFFECT ON ASSISTING SUICIDE.
Nothing in this act shall be construed to confer additional jurisdiction on any court to consider any claim related—
(1) to assisting suicide,
(2) a State law regarding assisting suicide.
SEC. 7. NO PRECEDENT FOR FUTURE LEGISLATION.
Nothing in this Act shall constitute a precedent with respect to future legislation, including the provision of private relief bills.
SEC. 8. NO EFFECT ON THE PATIENT SELF-DETERMINATION ACT OF 1990.
Nothing in this act shall affect the rights of any person under the Patient Self-Determination Act of 1990.
SEC. 9. SENSE OF THE CONGRESS.
It is the Sense of the Congress that the 109th Congress should consider policies regarding the status and legal rights of incapacitated individuals who are incapable of making decisions concerning the provi*1278sion, withholding, or withdrawal of foods, fluid, or medical care.
. The court is duty-bound to question at anytime in a proceeding the bona fides of its jurisdiction. Ortiz v. Fibreboard Corp., 527 U.S. 815, 831, 119 S.Ct. 2295, 2307, 144 L.Ed.2d 715 (1999); National Solid Wastes Mgmt. Ass'n v. Alabama Dep’t of Env’t Mgmt., 924 F.2d 1001, 1002 (11th Cir.1991). Given the rapid developments and sensitivities in this case, the need for deliberative study necessitated the delay in my questioning our jurisdiction.
. The entire text of Pub.L. 109-3 is attached as an appendix to this concurrence.
. See D.C. Court of Appeals v. Feldman, 460 U.S. 462, 476-82, 103 S.Ct. 1303, 1311-15, 75 L.Ed.2d 206 (1983); Rooker v. Fidelity Trust Co., 263 U.S. 413, 415-16, 44 S.Ct. 149, 150, 68 L.Ed. 362 (1923). Under the Rooker-Feldman doctrine, federal district and circuit courts lack jurisdiction to review the final judgments of state courts. See Verizon Md. Inc. v. Pub. Serv. Comm’n of Md., 535 U.S. 635, 644 n. 3, 122 S.Ct. 1753, 1759 n. 3, 152 L.Ed.2d 871 (2002); Narey v. Dean, 32 F.3d 1521, 1524-25 (11th Cir.1994). The doctrine applies where "(1) the party in federal court is the same as the party in state court; (2) the prior state court ruling was a final or conclusive judgment on the merits; (3) the party seeking relief in federal court had a reasonable opportunity to raise its federal claims in the state court proceeding; and (4) the issue before the federal court was either adjudicated by the state court or was inextricably intertwined with the state court’s judgment.” Amos v. Glynn County Bd. of Tax Assessors, 347 F.3d 1249, 1265 n. 11 (11th Cir.2003) (internal citations omitted). We are mindful that there exists an exception to Rooker-Feld-man when a federal statute authorizes federal appellate review of final state court decisions. See Dale v. Moore, 121 F.3d 624, 627 (11th Cir.1997). However, neither the ADA nor the Rehabilitation Act of 1973 provides an independent source of federal jurisdiction so as to fall within this exception. See id. at 628 (concluding that the ADA does not override Rook-ex-Feldman); Hason v. Office of Prof’l Med. Conduct, 314 F.Supp.2d 241, 248 (S.D.N.Y.2004) (applying Rooker-Feldman to bar claims brought under the Rehabilitation Act). Moreover, Pub.L. 109-3 does not fall within this exception because it is unconstitutional under the separation of powers doctrine as explained herein.
. In his dissenting opinion, Judge Tjoflat questions why I have not cited any cases for the proposition that Congress cannot, in a statute, withdraw our ability to use the doctrines of abstention, exhaustion and waiver. As I have explained, the Act is unprecedented in nature, and therefore a lack of controlling case law is unremarkable. Furthermore, my reading of Plaut, 514 U.S. 211, 115 S.Ct. 1447, 131 L.Ed.2d 328 (1995), demonstrates that unprecedented congressional acts can be lacking in constitutional propriety absent pri- or precedent. Moreover, I do not suggest that the provision of a standard of review is in a general sense a "rule of decision." See Nichols v. Hopper, 173 F.3d 820, 823 (11th Cir.1999)(Birch, J.)(stating that Congress may enact "standards,” such as a general standard of review, provided it "has left to the courts the judicial functions of applying those standards” prospectively). Rather, it is the abrogation of such standards in a single case, not in a category of cases like habeas corpus cases, which is improper. See Klein, 80 U.S. at 146 (discussing the impropriety of a legislative act which directs a "rule of decision” in a particular case pending before a court); Benjamin v. Jackson, 124 F.3d 162, 173 (2d Cir.1997)(citing Klein for the proposition that separation of powers is violated when a congressional act does not "permit[] courts to exercise their judicial powers independently” in a given case).
. The Act references the parties by name, designates the forum for the dispute, sets a time limit on decision-making, and suspends previous judgments, all so that the federal judiciary is instructed as to how to conduct this specific case.
. I hasten to note that the provisions in Section 2 of the Act cannot be construed as limitations of the exercise of jurisdiction. Section 1 of the Act grants jurisdiction; Section 2 purports to do more by directing the district court how to execute its judicial function. Accordingly, the provisions of Section 2 cannot be saved by creating the fiction that they are permissible limitations on the exercise of federal jurisdiction under Sheldon v. Sill, 49 U.S. (8 How.) 441, 12 L.Ed. 1147 (1850) and its progeny.
