Our prior opinion in this case,
First Gibraltar Bank, FSB v. Morales,
The issue presented for our determination is whether the Home Owners’ Loan Act, 1 12 U.S.C. §§ 1461-1468c, and Chapter 39 of Title 12 of the United States Code, formerly designated as the Alternative Mortgage Transaction Parity Act of 1982, together with regulations thereunder, have preempted the Texas homestead law to the extent that it prohibits lenders from enforcing liens on home equity created in reverse annuity mortgages or line of credit conversion mortgages. The district court granted summary judgment in favor of the defendants, concluding that the federal statutes and regulations did not preempt Texas homestead law. We affirm the judgment of the district court.
I. FACTUAL AND PROCEDURAL BACKGROUND
This lawsuit began as an action for declaratory and injunctive relief. First Gibraltar sought a judicial declaration that the HOLA and the Parity Act (together with the regulations promulgated thereunder) preempted portions of the Texas homestead law. In additiоn, First Gibraltar sought an injunction to prevent the Texas Attorney General and the Texas Consumer Credit Commissioner from enforcing the allegedly preempted portions of the Texas homestead law. In
First Gibraltar Bank, FSB v. Morales,
Before the issuance of our mandate, however, the Riegle-Neal Interstate Banking and Branching Efficiency Act of 1994 was *897 signed into law on September 29, 1994. 2 See Pub.L. No. 103-328, 108 Stat. 2338 (1994). Section 102(b) of this Act amends section 3 of the HOLA, 12 U.S.C. 1462a, by adding a new subsection (f) (the “Amendment”):
(f) STATE HOMESTEAD PROVISIONS. — No provision of this Act or any other provision of law administered by the Director [of the Office of Thrift Supervision] shall be construed as superseding any homestead provision of any State constitution, including any implementing State statute, in effect on the date of enactment of the Riegle-Neal Interstate Banking and Branching Efficienсy Act of 1994, or any subsequent amendment to such a State constitutional or statutory provision in effect on such date, that exempts the homestead of any person from foreclosure, or forced sale, for the payment of all debts, other than a purchase money obligation relating to the homestead, taxes due on the homestead, or an obligation arising from work and material used in constructing improvements on the homestead.
Pub.L. No. 103-328, § 102(b), 108 Stat. 2338, 2352 (1994). Our mandate has not yet issued in this appeal, and “[t]he normal rule in a civil case is that we judge it in accordance with the law as it exists at the time of our decision.”

III. ANALYSIS AND DISCUSSION
We begin by examining our authority to continue adjudicating this еase, and we then briefly discuss the relationship between the Amendment and our prior analysis.
A. Control Over Our Mandate
“Our control over a judgment of our court continues until our mandate has issued.”
Alphin v. Henson,
First Gibraltar hаs argued that pursuant to Federal Rule of Appellate Procedure 41(b), our mandate should have issued as soon as the Supreme Court denied certiorari. The Supreme Court denied certiorari in this case on October 3, 1994, and its order was received and filed on October 13, 1994. Prior to the denial of certiorari, however, we had stayed the mandate in this ease for two independent reasons; first, to permit an en banc poll (which is now unnecessary), and sеcond, to allow the State to petition for certiorari. The mandate was initially stayed well before the October 13, 1994 receipt of the Supreme Court’s order denying certiora-
*898
ri. Rule 41(b) does state in relevant part that “[t]he court of appeals must issue the mandate immediately when a copy of a Supreme Court order denying the petition for writ of certiorari is filed,” but because our stay was in effect (for a reason independent of the рetition for certiorari) prior to the receipt of the order, we retain discretionary control over our mandate.

Because the mandate is still within our control, we have the power to alter or to modify our judgment.
See Bryant,
B.Mootness
Despite the State’s contention that the Amendment moots this appeal, we find that the mootness framework is inapplicable to the posture of this lawsuit. The Amendment clearly affects the preemption analysis in this case. The Amendment does not, however, eliminate the “actual controversy” between the parties; it informs the decision, but it does not alter the original declaratory posture of the case. In othеr words, the parties still seek the same declaration of their rights, but such a declaration is now affected by the language of the Amendment. An “actual controversy,” capable of being resolved by a declaratory judgment, is still ongoing. See generally 10A Charles Alan Wright &' Arthur R. Miller and Mary Kay Kane, Federal Practice & Procedure § 2751 (1983). Thus, the mootness rubric is inappo-site, and the Munsingwear line of cases — a line that addresses the proper disposition of a lawsuit after a mootness determination — is inapplicable as well. Accordingly, we proceed to resolvе this appeal on the merits.
C.Context of the Amendment
Before we begin to analyze the effects of the Amendment, it is helpful to understand the relationship of the Amendment to our prior analysis. In our previous opinion, we noted that the Supreme Court’s preemption analysis required us to ask two questions: first, did the OTS intend to preempt Texas homestead law; and second, if the OTS did intend to preempt Texas homestead law, was the attempted preemption within the scope of the agency’s delegated authority?
See First Gibraltar Bank,
In this case, the Amendment clearly affects the second prong of the preemption analysis, as the statutory language addresses thе scope of the congressional grant of authority to the OTS. As a consequence, this second prong of the preemption analysis is now the focus of our attention. And, answering it as we do, we need not, and do not, address the first prong of the preemption analysis.
D.Infringement on the Judicial Branch
First Gibraltar initially argued that the HOLA expressed no limits on the
*899
FHLBB/OTS’s authority to regulate the lending practices of federal savings and loans, as the HOLA granted plenary authority to the agency to issue regulations preempting portions of the Texas homestead law. Following enactment of the Amendment, First Gibraltar contends that the language of the Amendment unconstitutionally undermines the power of the judicial branch by mandating a different construction of the HOLA, rather than by changing the underlying law. First Gibraltar relies on the Supreme Court cases of
United States v. Klein,
In analyzing the effect of this language, the Supreme Court’s decision in
Louisiana Pub. Serv. Comm’n
is quite instructive. In that ease, the Supreme Court addressed whether the Communications Act of 1934 granted the Federal Communications Commission (“FCC”) the authority to preempt inconsistent state regulations, specifically those that deviated from the FCC’s depreсiation practices.
See Louisiana Pub. Serv. Comm’n,
Section 152(b) of the Act, however, asserted the following:
[N]othing in this chapter shall be construed to apply or to give thе Commission jurisdiction with respect to (1) charges, classifications, practices, services, facilities, or regulations for or in connection with intrastate communication service_
Louisiana Pub. Serv. Comm’n,
If, as First Gibraltar argued, in enacting the HOLA Congress expressed no limits on the FHLBB/OTS’s authority to regulate the *900 lending practices of federal savings and loans, the law has been changed because the relevant language of the later Amendment provides such a limitation. The Amendment states that “[n]o provision of this Act or any other provision of law administered by the Director [of the Office of Thrift Supervision] shall be construed as superseding any homestead provision of any State constitution.” Just as this language was seen as a congressional denial of power to the FCC in Louisiana Pub. Serv. Comm’n, wе interpret the Amendment’s language as a congressional narrowing of authority to the OTS. Because the “shall be construed” language represents a congressional denial of power where once, arguendo, there were “no limits,” the Amendment represents a change in the underlying law and avoids any of First Gibraltar’s alleged separation of powers problems between the legislature and the judiciary.
Our conclusion is strengthened by the legislative history of the Amendmеnt. The Joint Explanatory Statement of the Committee of Conference accompanying the Amendment explicitly notes that:
[t]his amendment clarifies that neither the Home Owners’ Loan Act nor any other provision of law provides the Director of the Office of Thrift Supervision with the authority, through regulation or otherwise, to preempt Texas law in the area of homestead protection. By extension, housing creditors under the Alternative Mortgage Transaction Parity Act who were impacted by the decision in the First Gibraltar case also continue to be subject to Texas law in the area of homestead protection.
H.R.Conf.Rep. No. 651, 103d Cong., 2d Sess. 57-58 (1994) (emphasis added). Thus, it is clear that the Amendment was designed to restrict the congressional delegation of authority to the OTS with regard tp preemption of state homestead laws. This explicit legislative purpose is consistent with our analysis and with our conclusions about the statutory language itself.
Finally, numerous statutory schemes use the language “shall be construed” to describe thе limitations and boundaries of a congressional delegation of authority. 5 See, e.g., McCarran-Ferguson Insurance Regulation Act, 15 U.S.C. § 1012(b) (“No Act of Congress shall be construed to invalidate, impair, or supersede any law enacted by any State for the purpose of regulating the business of insurance....”); ERISA, 29 U.S.C. § 1144(b)(2)(A) (“Except as provided in sub-paragraph (B), nothing in this subchapter shall be construed to exempt or relieve any person from any law of any State which regulates insurance, banking, or securities.”); Omnibus Budget Reconciliation Act, 42 U.S.C.. § 1395ss(j) (“Nothing in this section shall be construed so as to affect the right of any State to regulate medicare supplemental policies which, under the provisions of this section, are considered to be issued in another State.”). These statutes are not constitutionally infirm because of their use of “shall be construed,” and we see no reason to reach a different result with regard to the Amendment in this case. 6
*901 E. Infringement on the Executive Branch
First Gibraltar also argues that the Amendment infringes on the authority of the executive branch “because it overturns agency action that has developed over at least fifteen years without suggesting that the agency overreached its authority or otherwise acted improperly.” Similar to its infringement on the judiciary argument, First Gibraltar contends that “Congress cannot merely exercise a veto power over a legitimate exercise of executive authоrity without changing the agency’s instructions, and without mandating any change in the agency’s future conduct or regulatory scheme.”
Once again, however, we disagree with First Gibraltar’s characterization, as Congress has narrowed the agency’s authority. As part of its legislative powers, Congress designates the scope of agency authority, and if Congress so chooses, it can subsequently restrict or limit that delegation of power to the agency. The Supreme Court has noted that “Congress ultimately controls administrative agencies in the legislation that creates them,” and more importantly, the Court has observed that “Congress must abide by its delegation of authority
until that delegation is legislatively altered or revoked." See Chadha,
Furthermore, and perhaps most importantly, this circuit has accorded deference to an agency’s determination of its own statutory authority.

See NCNB Tex. Nat’l Bank v. Cowden,
OTS understands the Gonzalez Amendment to preclude the agency, as of the date of enactment of the provision, from construing any provision of law administered by the Director as superseding the homestead provisions of Texas law that are at issue in this case.... OTS reads the amendment to change the applicable law and now to subject federal savings associations and certain other financial services institutions to the conditions of the Texas homestead laws.
According deference to the OTS’s interpretation of its statutory authority, as we must, it is clear that even the agenсy in question construes the Amendment as a limitation on
*902
its authority. Finding no constitutional infirmity to dissuade us from this construction, we disagree with First Gibraltar’s assertions, and we find that the Amendment is constitutionally valid.
Cf. Louisiana Pub. Serv. Comm’n,
F. Effectiveness of the Amendment
First Gibraltar also cоntends that the Amendment is ineffective because the OTS regulations had already preempted the state homestead provisions before the Amendment was passed. Thus, First Gibraltar argues that “the conflicting provisions of the Texas homestead laws were not in effect on the date that Congress enacted the ... Amendment, and the Amendment cannot, and does not attempt to resurrect previously preempted state law.”
Assuming
arguendo
that portions of the Texas homestead law were preempted prior to the enactment of the Amendment, we cannot agree with First Gibraltar’s apparent assumption that once a law is preempted, it forever remains preempted and ineffective. First of all, we note that First Gibraltar fails to cite any authority in support of this proposition. Second, and more importantly, state law can be preempted by federal legislation and by regulations promulgated by federal agencies acting within the scope of their con-gressionally delegated authority.
See Louisiana Pub. Serv. Comm’n,
Similarly, we took great pains to make clear in our earlier decision that this lawsuit deals only with two types of alternative mortgage instruments — the reverse annuity mortgage (“RAM”) and the line of credit conversion mortgage.
See First Gibraltar Bank,
TV. CONCLUSION
For the foregoing reasons, the judgment of the district court is AFFIRMED. The mandate shall issue forthwith.
Notes
. Terms defined in our prior opinion will have the same meaning herein as therein defined.
. At this time, the Statе's petition for certiorari to the Supreme Court was pending.
. To the extent that appellants attach any meaning to the Supreme Court's denial of certiorari, the language of the
Alphin
court is instructive: "The law is clear that the denial of certiorari decides nothing except that the writ will not be granted for reasons which are undisclosed.”
Al-phin,
. It is important to note that we do not comment on whether First Gibraltar's interpretation of
Klein
and
Wheeling Bridge
is accurate. Instead, we merely determine that
as interpreted by First Gibraltar,
these cases do nоt warrant a finding that the Amendment is unconstitutional because the Amendment does change the existing law (as that law is construed by First Gibraltar).
Cf. Robertson v. Seattle Audubon Soc’y,
- U.S. -, -,
. Indeed, the appendix to the State's brief indicates that 2,020 statutory sections of the United States Code contain the language "shall be construed."
. First Gibraltar attempts to distinguish these statutes from the Amendment by noting that "[s]uch provisions ... are not, as in this case, enacted many years after the original legislation with the express purpose of overturning the result of a specific judicial decision.” We conclude, however, that this is not a meaningful distinction. Congress retains the power to narrow the scope of its delegatеd authority at any time.
See INS v. Chadha,
Even though the Amendment's legislative history states that it "overturns an interpretation of [the HOLA] in
First Gibraltar Bank v. Morales,"
such an express purpose is not troublesome because Congress constitutionally restricted the scope of authority delegated to the OTS. Moreover, the simple enactment of legislation to overturn a particular judicial decision is not problematic in itself.
See, e.g., Louisiana Pub. Serv. Comm’n,
. We follow our own case law, recognizing that, at least in one context, there is some debate on this subject.
