The question presented is whether the “enrolled bill rule” articulated by the Supreme Court in
Marshall Field & Co. v. Clark,
BACKGROUND
Plaintiff OneSimpleLoan is a company that markets and finances student loans. *199 Plaintiffs Carina D. Ball and Nathan Ba-zyk are individual borrowers who consolidated their student loans under the Federal Family Education Loan (“FFEL”) Program. Plaintiffs allege that they have suffered injury on account of provisions in the DRA that (1) prohibit a method of refinancing FFEL consolidated loans and (2) impose conditions that inhibit companies from providing lower interest rates and better benefits on FFEL consolidated loans. They brought an action against defendants, the United States Secretary of Education and the Secretary’s Regional Representative for Region II (which includes New York), seeking injunctive and declaratory relief. Plaintiffs alleged, inter alia, that the DRA was unconstitutional because the bill passed by the House of Representatives was not identical to the bill passed earlier hy the Senate and presented later to the President. As evidence of this failure to pass identical texts, plaintiffs pointed to a difference between (1) the “engrossed bill” transmitted from the Senate to the House of Representatives after the Senate vote, and (2) the “enrolled bill” presented to the President after having been signed by the Speaker of the House of Representatives and the President Pro Tempore of the Senate.
A. The Bicameralism and Presentment Clause, the Appropriations Clause, Engrossed Bills, and Enrolled Bills
The Bicameralism and Presentment Clause mandates that “[ejvery Bill which shall have passed the House of Representatives and the Senate, shall, before it become a Law, be presented to the' President of the United States.... ” U.S. Const, art. I, § 7, cl. 2. A law has been enacted in conformance with this constitutional mandate only if “(1) a bill containing its exact text was approved by a majority of the Members of the House of Representatives; (2) the Senate approved precisely the same text; and (3) that text was signed into law by the President.”
Clinton v. City of New York,
“Congress has established specific procedures governing passage of a bill.”
Public Citizen,
Every bill ... in each House of Congress shall, when such bill ... passes either House, be printed, and such printed copy shall be called the engrossed bill_Said engrossed bill ... shall be signed by the Clerk of the House or the Secretary of the Senate, and shall be sent to the other House, and in that form shall be dealt with by that House and its officers, and, if passed, returned signed by said Clerk or Secretary. When such bill ... shall have passed both Houses, it shall be printed and shall then be called the enrolled bill, ... and shall be signed by the presiding officers of both Houses and sent to the President of the United States.
1 U.S.C. § 106 (emphasis added).

Charles Tiefer,
Congressional Practice and Procedure
247-50 (1989) (discussing the processes of “engrossment” and “enrollment”). “An ‘engrossed bill’ is thus one that has passed one chamber of Congress, while an ‘enrolled bill’ has passed both the House and the Senate.”
Public Citizen,
B. Enactment of the DRA
The DRA, signed by the President on February 8, 2006, is an omnibus budget act whose broad-ranging provisions affect not just educational lending, but also, inter alia, Medicare and Medicaid laws, Hurricane Katrina relief, the transition to digital television broadcasting, and the filing fees for civil actions in federal district courts. See id.
The following facts regarding the DRA’s enactment are drawn from plaintiffs’ complaint. 1 Most of the facts contained in the complaint are summarized by the District of Columbia Circuit in Public Citizen-. 2
[I]n the Fall of 2005, the House and Senate passed different versions of a budget bill referred to as S.1932. To iron out the differences, the legislation was sent to a conference committee. The committee produced a conference report which failed to pass the Senate. Shortly thereafter the Senate passed an amended version of S.1932 wherein § 5101 specified a 13-month duration of Medicare payments for certain durable medical equipment. 3 However, when the Senate clerk transmitted the engrossed S.1932 to the House, he mistakenly changed § 5101 of the bill to reflect a 36-month duration of payments for durable medical equipment rather than the 13-month duration actually approved by the Senate. The House voted on this engrossed bill, including the erroneous duration figure. 4 Because the legislation originated in the Senate, the House returned it to the Senate for enrollment. The Senate clerk, recognizing the transcription error in the engrossed bill, altered the text of the enrolled bill so that it included a 13-month rather than a 36-month duration. The version of the DRA signed by the presiding officers contains the 13-month figure. Thus, since the 13-month duration term in the enrolled bill passed the Senate but not the House, the President signed legislation that did not actually pass both houses of Congress in precisely the same form.
Id. at 1345. Additionally, plaintiffs in the instant case allege that (1) there existed a “legally improper arrangement among certain representatives of the House, Senate *201 and Executive Branch to have the President sign” legislation that had not been enacted pursuant to the Constitution; (2) the Speaker of the House of Representatives and the President Pro Tempore of the Senate were aware of the discrepancy between the engrossed bill and the enrolled bill when they signed the enrolled bill; and (3) after the President signed the DRA, the Senate passed a concurrent resolution hoping to rectify the constitutional deficiency, but the House of Representatives never passed this resolution.
C. Proceedings in the District Court
Plaintiffs commenced this action in April 2006. In May 2006, they moved for summary judgment and, in the alternative, for a preliminary injunction that would prevent implementation of the allegedly injurious student loan provisions of the DRA. Defendants cross-moved to dismiss the complaint pursuant to Fed.R.Civ.P. 12(b)(1) and Fed.R.Civ.P. 12(b)(6). In a decision and order dated June 9, 2006, the District Court determined that plaintiffs’ constitutional claims were subject to dismissal under the enrolled bill rule announced in
Marshall Field.
The District Court rejected plaintiffs’ arguments that (1) the enrolled bill rule was dicta and (2) in any event, the Supreme Court had overruled the enrolled bill rule in
United States v. Munoz-Flores,
Although certain non-constitutional claims remained pending before the District - Court, plaintiffs filed a -notice of appeal on June 12, 2006. When those non-constitutional claims were mooted by new legislation, plaintiffs filed a second notice of appeal on June 26, 2006, on the theory that the June 9, 2006 decision and order had become final. In an order entered on August 9, 2006, the District Court determined that plaintiffs had never appealed from a final order and that it therefore retained jurisdiction to decide the issue of standing with respect to the constitutional claims. It then concluded that plaintiffs lacked standing, in part because they had not alleged an injury that would likely be redressed by a judgment in their favor.

DISCUSSION
A. Marshall Field
In
Marshall Field,
several importers protesting the assessment of duties under
*202
the Tariff Act of October 1, 1890 claimed that “the act was not a law of the United States.”
The contention of the appellants is that [the] enrolled act, in the custody of the Secretary of State, and appearing, upon its face to have become a law in the mode prescribed by the Constitution, is to be deemed an absolute nullity, in all its parts, because — such is the allegation — it is shown by the Congressional record of proceedings, reports of committees of each house, reports of committees of conference, and other papers printed by authority of Congress, and having reference to [the bill in question], that a section of the bill, as it finally passed, was not in the bill authenticated by the signatures of the presiding officers of the respective houses of Congress, and approved by the President.
Id.
at 668-69,
The Supreme Court rejected this interpretation of the Journal Clause and stated that nothing in the Constitution “prescribe[s] the mode in which the fact of the original passage of a bill by the House of Representatives and the Senate shall be authenticated, or precluded] Congress from adopting any mode to that end which its wisdom suggests.”
Id.
at 671,
The Supreme Court in
Marshall Field
admitted that the rule thereby established would allow the continued enforcement of legislation that had not been enacted in the manner prescribed by the Constitution.
See id.
at 675,
[b]etter, far better, that a provision should occasionally find its way into the statute through mistake, or even fraud, than that every act, state and national, should at any and all times be liable to be put in issue and impeached by the *203 journals, loose papers of the legislature, and parole evidence. Such a state of uncertainty in the statute laws of the land would lead to mischiefs absolutely intolerable.
Id.
(quoting
Sherman v. Story,
In concluding its discussion of Congress’s alleged failure to pass the precise text of the act in question, the Court set forth “a clear rule” requiring the judicial branch to treat an enrolled bill signed by the presiding officers of the House and Senate as conclusive evidence of the text passed by both houses of Congress.
Public Citizen,
The rule articulated by the Supreme Court in
Marshall Field
became known as the “enrolled bill rule” and has been described by our Court as “a longstanding rule, invoked by many courts, including the Supreme Court and our own Court.”
United States v. Pabon-Cruz,
The plain language of Marshall Field appears to foreclose plaintiffs’ constitutional claims in the instant case, which would require our Court to look beyond the authenticated enrolled bill for evidence that the House and Senate did not pass identical texts. Yet plaintiffs present a variety of arguments urging us to decide that Marshall Field does not' mean what it says. They also assert that they have standing under the Constitution to pursue their claims. We conclude that plaintiffs’ arguments regarding the inapplicability of the enrolled bill rule are without merit, and we note that it is for the Supreme Court rather than a court of inferior jurisdiction to determine whether the venerable enrolled bill rule requires revision in light of technological and political developments since Marshall Field was decided in 1892. We also conclude that a court may dismiss claims pursuant to the enrolled bill rule before addressing whether a plaintiff has standing. ■
B. The Enrolled Bill Rule Is a “Nom-Merits Threshold Ground for Dismissal”
We first consider whether it is necessary for a court to determine if a plaintiff satisfies the “irreducible constitutional minimum of standing” before deciding whether the enrolled bill rule applies.
Lujan,
As the District of Columbia Circuit pointed out in
Public Citizen,
because the enrolled bill rule is a “non-merits threshold ground for dismissal,”
Public Citizen,
In the instant case, there is no dispute as to whether the Speaker of the House of Representatives and the President Pro Tempore of the Senate signed the enrolled bill that would subsequently become the DRA. Thus, we need only review the District Court’s legal conclusions regarding application of the enrolled bill rule to the particular claims at issue.
C. The Enrolled Bill Rule Was Not Dicta
Plaintiffs and
amicus
Public Citizen argue that the Supreme Court’s holding in
Marshall Field
extended only to congressional journals and that the prohibition against considering all “other documents printed by authority of Congress,”
Marshall Field,
Plaintiffs also argue that the scope of the holding of
Marshall Field
was cast into doubt by the Supreme Court’s inspection of congressional journals in
United States v. Ballin,
Indeed, the Supreme Court’s analysis in
Ballin
appears to reinforce its reasoning in
Marshall Field.
In
Ballin,
the Court inspected the House’s journal only after “[assuming that by reason of [the Journal Clause] reference may be had to the journal, to see whether the yeas and nays were ordered, and if so, what was the vote disclosed thereby.”
Id.
In contrast, the
Marshall Field
Court made plain that the Constitution grants Congress full discretion in deciding how to authenticate the particular text of a bill passed by both houses.
See Marshall Field,
D. The Enrolled Bill Rule Has Not Been Overruled or Modified by the Supreme Court
Plaintiffs’ principal contention on appeal is that, whatever
Marshall Field
meant in 1892, the Supreme Court has subsequently restricted its application “to cases where a constitutional requirement binding Congress is absent,” Appellants’ Reply Br. 1, or has at least “squarely confine[d]
Field
to a Journal Clause controversy,”
id.
at 3. Plaintiffs’ sole support for this argument is what Judge Edwards of the District of Columbia Circuit styled an “oblique footnote” in
Munoz-Flores. Public Citizen,
In
Munoz-Flores,
a criminal defendant challenged the constitutionality of a provision of the Victims of Crime Act, 18 U.S.C. § 3013. He argued that the provision, “which requires courts to impose a mandatory special assessment on any person convicted of a felony misdemeanor,”
Munoz-Flores,
Justice Scalia, in an opinion concurring in the judgment, stated that
Marshall Field
prohibits judicial inquiry into the origination of a statute where an authenticated enrolled bill contains the designation “H.J. Res.,” an abbreviation for “House Joint Resolution.”
See id.
at 408-10,
[Justice Scalia] contends that Congress’ resolution of the constitutional question in passing the bill bars this Court from independently considering that question. The only case he cites for his argument is Marshall Field & Co. v. Clark. But Field does not support his argument. That case concerned “the nature of the evidence” the Court would consider in determining whether a bill had actually passed Congress. Appellants had argued that the constitutional Clause providing that “[e]ach House shall keep a Journal of its Proceedings” implied that whether a bill had passed must be determined by an examination of the journals. The Court rejected that interpretation of the Journal Clause, holding that the Constitution left it to Congress to determine how a bill is to be authenticated as having passed. In the absence of any *207 constitutional requirement binding Congress, we stated that “[t]he respect due to coequal and independent departments” demands that the courts accept as passed all bills authenticated in the manner provided by Congress. Where, as here, a constitutional provision is implicated, Field does not apply.
Munoz-Flores,
Plaintiffs interpret this footnote as rendering the enrolled bill rule inapplicable to their constitutional claims under the Bicameralism and Presentment Clause and the Appropriations Clause. We disagree. Although “the language of the
Munoz-Flores
footnote is cumbersome, making it difficult to discern precisely what the Court meant to say,”
Public Citizen,
E. We May Not Create Exceptions to the Enrolled Bill Rule Based on Technological and Political Developments Since Marshall Field Was Decided
Plaintiffs and amici offer two additional reasons why the enrolled bill rule should not apply in the instant case: (1) the engrossed bill, whose production is required by statute, is more reliable than the congressional documents presented as evidence of a constitutional violation in Marshall Field; and (2) plaintiffs allege a conspiracy to subvert the Constitution by the presiding officers of Congress, and the President. Neither of these arguments is availing.
First, although technological advances in printing and copying since the late nineteenth century may have removed some of the sources of unreliability in congression
*208
al documents, the facts alleged by plaintiffs in this case reveal that even engrossed bills printed today are subject to error or mishandling. Indeed, such advances may provide new ways to alter a bill’s text during the legislative process. Additionally, while the Supreme Court in
Marshall Field
contemplated that Congress could change its internal bill authentication procedure if it wanted to,
see Marshall Field,
Second, we do not agree with plaintiffs’ argument (supported by several members of the House of Representatives acting as amici) that Marshall Field creates an exception to the enrolled bill rule in certain cases involving allegations that the presiding officers of Congress and the President of the United States conspired to violate the Constitution by enacting legislation that had not passed both the House and Senate. As it happens, the Supreme Court in Marshall Field responded to the contention that under the enrolled bill rule “it becomes possible for the Speaker of the House of Representatives and the President of the Senate to impose upon the people as a law a bill that was never passed by Congress”:
But this possibility is too remote to be seriously considered in the present inquiry. It suggests a deliberate conspiracy to which the presiding officers, the committees on enrolled bills, and the clerks of the two houses must necessarily be parties, all acting with a common purpose to defeat an expression of the popular will in the mode prescribed by the Constitution.
Marshall Field,
In the last analysis, even if plaintiffs’ arguments support the creation of exceptions to the enrolled bill rule in some circumstances (or militate toward abandoning the rule altogether), we are not at liberty to depart from binding Supreme Court precedent “unless and until [the] Court reinterpretes]” that precedent.
Agostini v. Felton,
For the foregoing reasons, the judgment of the District Court is Affirmed.
Notes
. For the moment, we defer discussion of whether it is necessary to accept as true the facts presented in a plaintiff's pleadings when a defendant moves for dismissal on the basis of the enrolled bill rule. See pages 203-04 post (discussing the enrolled bill rule's status as a non-merits threshold ground for dismissal).
. In
Public Citizen,
the District of Columbia Circuit dealt with the same constitutional challenge to the DRA that we do in the instant case.
Public Citizen,
Several district courts in other Circuits have rejected similar constitutional challenges to the DRA.
See Zeigler v. Gonzales,
No. 06-0080-CG-M,
. The Vice President of the United States, as President of the Senate, U.S. Const, art. I, § 3, cl. 4, cast a tie-breaking vote in favor of the bill.
. The bill passed by a vote of 216 to 214.
. Because plaintiffs' multiple notices of appeal ensure timeliness, and because we can nostra sponte address any argument on standing not presented to or decided by the District Court, we need not consider whether it was possible for plaintiffs to appeal at any time before August 9, 2006, or whether the District Court properly concluded that it retained jurisdiction to decide the standing issue.
. The Journal Clause states that "[e]ach House shall keep a Journal of its Proceedings, and from time to time publish the same, excepting such Parts as may in their Judgment require Secrecy; and the Yeas and Nays of the Members of either House on any question shall, at the Desire of one fifth of those Present, be entered on the Journal.” U.S. Const, art. I, § 5, cl. 3.
. In other words, the
Munoz-Flores
footnote refuses to extend, but does not retract, the enrolled bill rule. That said, we do agree with plaintiffs that the Supreme Court has been less than clear in explaining why courts may probe congressional documents when adjudicating some types of constitutional claims but not others. In the context of a claim that seeks to impeach the authenticated text of an enrolled bill, the Court may regard as unique the "usage, the orderly conduct of legislative proceedings, and the rules under which the [houses of Congress] have acted since the organization of the government, requiring] that mode of authentication.”
Marshall Field,
