Justice Kennedy
delivered the opinion of the Court.
In various Alabama counties voters elect members of county commissions whose principal function is to supervise [494]*494and control the maintenance, repair, and construction of the county roads. See Ala. Code §§11-3-1, 11-3-10 (1975). The consolidated appeals now before us concern certain changes in the decisionmaking authority of the elected members on two different county commissions, and the question to be decided is whether these were changes “with respect to voting” within the meaning of § 5 of the Voting Rights Act of 1965, 79 Stat. 439, as amended, 42 U. S. C. § 1973c. These cases have significance well beyond the two county commissions; for the appellants, and the United States as amicus curiae, ask us to adopt a rule embracing the routine actions of state and local governments at all levels. We must interpret the provisions of § 5, which require a jurisdiction covered by the Act to obtain either judicial or administrative preclearance before enforcing any new “voting qualification or prerequisite to voting, or standard, practice, or procedure with respect to voting.”
[495]*495I
To determine whether there have been changes with respect to voting, we must compare the challenged practices with those in existence before they were adopted. Absent relevant intervening changes, the Act requires us to use practices in existence on November 1, 1964, as our standard of comparison.
A
We consider first the Etowah County Commission. On November 1, 1964, commission members were elected at large under a "residency district" system. The entire electorate of Etowah County voted on candidates for each of the five seats. Four of the seats corresponded to the four [496]*496residency districts of the county. Candidates were required to reside in the appropriate district. The fifth member, the chairman, was not subject to a district residency requirement, though residency in the county itself was a requirement.
Each of the four residency districts functioned as a road district. The commissioner residing in the district exercised control over a road shop, equipment, and road crew for that district. It was the practice of the commission to vote as a collective body on the division of funds among the road districts, but once funds were divided each commissioner exercised individual control over spending priorities within his district. The chairman was responsible for overseeing the solid waste authority, preparing the budget, and managing the courthouse building and grounds.
Under a consent decree issued in 1986, see Dillard v. Crenshaw County, Civ. Action No. 85-T-1332-N (MD Ala., Nov. 12,1986), the commission is being restructured, so that after a transition period there will be a six-member commission, with each of the members elected by the voters of a different district. The changes required by the consent decree were precleared by the Attorney General. For present purposes, it suffices to say that when this litigation began the commission consisted of four holdover members who had been on the commission before the entry of the consent decree and two new members elected from new districts. Commissioner Williams, who is white, was elected from new district 6, and Commissioner Presley, who is black, was elected from new district 5. Presley is the principal appellant in the Etowah County case. His complaint relates not to the elections but to actions taken by the four holdover members when he and Williams first took office.
On August 25, 1987, the commission passed the “Road • Supervision Resolution.” It provided that each holdover commissioner would continue to control the workers and [497]*497operations assigned to his respective road shop, which, it must be remembered, accounted for all the road shops the county had. It also gave the four holdovers joint responsibility for overseeing the repair, maintenance, and improvement of all the roads of Etowah County in order to pick up the roads in the districts where the new commissioners resided. The new commissioners, now foreclosed from exercising any authority over' roads, were given other functions under the resolution. Presley was to oversee maintenance of the county courthouse and Williams the operation of the engineering department. The Road Supervision Resolution was passed by a 4-to-2 margin, with the two new commissioners dissenting.
The same day the Road Supervision Resolution was passed, the commission passed a second, the so-called “Common Fund Resolution.” It provides in part that
“all monies earmarked and budgeted for repair, maintenance and improvement of the streets, roads and public ways of Etowah County [shall] be placed and maintained in common accounts, [shall] not be allocated, budgeted or designated for use in districts, and [shall] be used county-wide in accordance with need, for the repair, maintenance and improvement of all streets, roads and public ways in Etowah County which are under the jurisdiction of the Etowah County Commission.” App. to Juris. Statement in No. 90-711, p. 49a.
This had the effect of altering the prior practice of allowing each commissioner full authority to determine how to spend the funds allocated to his own district. The Etowah County Commission did not seek judicial or administrative preclearance of either the Road Supervision Resolution or the Common Fund Resolution. The District Court held that the Road Supervision Resolution was subject to preclearance but that the Common Fund Resolution was not. No appeal was [498]*498taken from the first ruling, so only the Common Fund Resolution is before us in the Etowah County case.
B
We turn next to the background of the Russell County Commission. On November 1, 1964, it had three commissioners. Like the members of the Etowah County Commission before the consent decree change, Russell County Commissioners were elected at large by the entire electorate, subject to a requirement that a candidate for commissioner reside in the district corresponding to the seat he or she sought. A 1972 federal court order, see Anthony v. Russell County, No. 961-E (MD Ala., Nov. 21, 1972), required that the commission be expanded to include five members. The two new members were both elected at large from one newly created residency district for Phenix City, the largest city in Russell County. Following the implementation of the court order, each of the three rural commissioners had individual authority over his own road shop, road crew, and equipment. The three rural commissioners also had individual authority for road and bridge repair and construction within their separate residency districts. Although funding for new construction and major repair projects was subject to a vote by the entire commission, individual commissioners could authorize expenditures for routine repair and maintenance work as well as routine purchase orders without seeking approval from the entire commission.
Following the indictment of one commissioner on charges of corruption in Russell County road operations, in May 1979 the commission passed a resolution delegating control over road construction, maintenance, personnel, and inventory to the county engineer, an official appointed by the entire commission and responsible to it. The engineer’s previous duties had been limited to engineering and surveying services for the separate road shops and running a small crew devoted to pothole repair. Although the May 1979 resolution [499]*499may have sufficed for the necessary delegation of authority to the county engineer, compare Ala. Code § 23-1-80 (1975) with Ala. Code § 11-6-3 (1975), the commission also requested the state legislature to pass implementing legislation. The Alabama Legislature did so on July 30, 1979, when it enacted Act No. 79-652, 1979 Ala. Acts 1132. It provides in pertinent part:
“Section 1. All functions, duties and responsibilities for the construction, maintenance and repair of public roads, highways, bridges and ferries in Russell County are hereby vested in the county engineer, who shall, insofar as possible, construct and maintain such roads, highways, bridges and ferries on the basis of the county as a whole or as a unit, without regard to district or beat lines.”
The parties refer to abolition of the individual road districts and transfer of responsibility for all road .operations to the county engineer as the adoption of a “Unit System.” Neither the resolution nor the statute which authorized the Unit System was submitted for preclearance under § 5.
Litigation involving the Russell County Commission led to a 1985 consent decree, see Sumbry v. Russell County, No. 84-T-1386-E (MD Ala., Mar. 17,1985), that enlarged the commission to seven members and replaced the at-large election system with elections on a district-by-district basis. Without any mention of the Unit System changes, the consent decree was precleared by the Department of Justice under §5. Following its implementation, appellants Mack and Gosha were elected in 1986. They are Russell County’s first black county commissioners in modern times.
C
In May 1989, appellants in both cases now before us filed a single complaint in the District Court for the Middle District of Alabama, alleging racial discrimination in the [500]*500operation of the Etowah and Russell County Commissions in violation of prior court orders, the Constitution, Title VI of the Civil Rights Act of 1964, 42 U. S. C. § 2000d, and § 2 of the Voting Rights Act, 42 U. S. C. § 1973. In a series of amended complaints, appellants added claims under § 5. The § 5 claims alleged that Etowah County had violated the Act by failing to obtain preclearance of the 1987 Road Supervision and Common Fund Resolutions, and that Russell County had failed to preclear the 1979 change to the Unit System. Pursuant to 28 U. S. C. § 2284, a three-judge District Court was convened to hear appellants' § 5 claims. The other claims still pend in the District Court.
With respect to the issues now before us, a majority of the District Court held that neither the Common Fund Resolution of the Etowah County Commission nor the adoption of the Unit System in Russell County was subject to § 5 pre-clearance. The court held that changes in the responsibilities of elected officials are subject to preclearance when they "effect a significant relative change in the powers exercised by governmental officials elected by, or responsible to, substantially different constituencies of voters." App. to Juris. Statement in No. 90-711, pp. 13a-14a. Applying its test, the court found that the Common Fund Resolution in Etowah County did not effect a significant change and adoption of the Unit System in Russell County did not transfer authority among officials responsible to different constituencies. We noted probable jurisdiction. 500 U. S. 914 (1991). We affirm the District Court but adopt a different interpretation of § 5 as the rationale for our decision.
II
We first considered the Voting Rights Act in South Carolina v. Katzenbach, 383 U. S. 301 (1966). Although we acknowledged that suspension of new voting regulations pending preclearance was an extraordinary departure from the traditional course of relations between the States and the [501]*501Federal Government, id., at 334, we held it constitutional as a permitted congressional response to the unremitting attempts by some state and local officials to frustrate their citizens’ equal enjoyment of the right to vote. See id., at 308-315.
After South Carolina v. Katzenbach upheld the Voting Rights Act against a constitutional challenge, it was not until we heard Allen v. State Bd. of Elections, 393 U. S. 544 (1969), that we were called upon to decide whether particular changes were covered by §5. There'we rejected a narrow construction, one which would have limited § 5 to state rules prescribing who may register to vote. We held that the section applies also to state rules relating to the qualifications of candidates and to state decisions as to which offices shall be elective. Id., at 564-565. We observed that “[t]he Voting Rights Act was aimed at the subtle, as well as the obvious, state regulations which have the effect of denying citizens their right to vote because of their race.” Id., at 565. Our decision, and its rationale, have proved sound, and we adhere to both.
In giving a broad construction to §5 in Allen, we noted that “Congress intended to reach any state enactment which altered the election law of a covered State in even a minor way.” Id., at 566. Relying on this language and its application in later cases, appellants and the United States now argue that because there is no de minimis exception to § 5, the changes at issue here must be subject to preclearance. E. g., Brief for United States as Amicus Curiae 21-22. This argument, however, assumes the answer to the principal question in the case: whether the changes at issue are changes in voting, or as we phrased it in Allen, “election law.”
We agree that all changes in voting must be precleared and with Allen’s, holding that the scope of §5 is expansive within its sphere of operation. That sphere comprehends all changes to rules governing voting, changes effected [502]*502through any of the mechanisms described in the statute. Those mechanisms are any “qualification or prerequisite” or any “standard, practice, or procedure with respect to voting.”
The principle that § 5 covers voting changes over a wide range is well illustrated by the separate cases we considered in the single opinion for the Court in Allen. Allen involved four cases. The eponymous Allen v. State Bd. of Elections concerned a change in the procedures for the casting of write-in ballots. 393 U. S., at 570-571. In Whitley v. Williams, there were changes in the requirements for independent candidates running in general elections. Id., at 551. The challenged procedure in Fairley v. Patterson resulted in a change from single-district voting to at-large voting. Id., at 550. The remaining case, Bunton v. Patterson, involved a statute which provided that officials who in previous years had been elected would be appointed. Id., at 550-551. We held that the changes in each of the four cases were covered by § 5.
Our cases since Allen reveal a consistent requirement that changes subject to §5 pertain only to voting. Without implying that the four typologies exhaust the statute’s coverage, we can say these later cases fall within one of the four factual contexts presented in the Allen cases. First, we have held that § 5 applies to cases like Allen v. State Bd. of Elections itself, in which the changes involved the manner of voting. See Perkins v. Matthews, 400 U. S. 379,387 (1971) (location of polling places). Second, we have held that §5 applies to cases like Whitley v. Williams, which involve candidacy requirements and qualifications. See NAACP v. Hampton County Election Comm’n, 470 U. S. 166 (1985) (change in filing deadline);. Hadnott v. Amos, 394 U. S. 358 (1969) (same); Dougherty County Bd. of Ed. v. White, 439 U. S. 32 (1978) (rule requiring board of education members to take unpaid leave of absence while campaigning for office). Third, we have applied § 5 to cases like Fairley v. Patterson, [503]*503which concerned changes in the composition of the electorate that may vote for candidates for a given office. See Perkins v. Matthews, 400 U. S., at 394 (change from ward to at-large elections); id., at 388 (boundary lines of voting districts); City of Richmond v. United States, 422 U. S. 358 (1975) (same). Fourth, we have made clear that §5 applies to changes, like the one in Bunion v. Patterson, affecting the creation or abolition of an elective office. See McCain v. Lybrand, 465 U. S. 236 (1984) (appointed officials replaced by elected officials); Lockhart v. United States, 460 U. S. 125 (1983) (increase in number of city councilors).
The first three categories involve changes in election procedures, while all the examples within the fourth category might be termed substantive changes as to which offices are elective. But whether the changes are of procedure or substance, each has a direct relation to voting and the election process.
III
A comparison of the changes at issue here with those in our prior decisions demonstrates that the present cases do not involve changes covered by the Act.
The Etowah County Commission’s Common Fund Resolution is not a change within any of the categories recognized in Allen or our later cases. It has no connection to voting procedures: It does not affect the manner of holding elections, it alters or imposes no candidacy qualifications or requirements, and it leaves undisturbed the composition of the electorate. It also has no bearing on the substance of voting power, for it does not increase or diminish the number of officials for whom the electorate may vote. Rather, the Common Fund Resolution concerns the internal operations of an elected body.
Appellants argue that the Common Fund Resolution is a covered change because after its enactment each commis[504]*504sioner has less individual power than before the resolution. A citizen casting a ballot for a commissioner today votes for an individual with less authority than before the resolution, and so, it is said, the value of the vote has been diminished.
Were we to accept appellants’ proffered reading of § 5, we would work an unconstrained expansion of its coverage. Innumerable state and local enactments having nothing to do with voting affect the power of elected officials. When a state or local body adopts a new governmental program or modifies an existing one it will often be the case that it changes the powers of elected officials. So too, when a state or local body alters its internal operating procedures, for example, by modifying its subcommittee assignment system, it “implicate^] an elected official’s decisionmaking authority.” Brief for United States as Amicus Curiae 17-18 (emphasis in original).
Appellants and the United States fail to provide a workable standard for distinguishing between changes in rules governing voting and changes in the routine organization and functioning of government. Some standard is necessary, for in a real sense every decision taken by government implicates voting. This is but the felicitous consequence of democracy, in which power derives from the people. Yet no one would contend that when Congress enacted the Voting Rights Act it meant to subject all or even most decisions of government in covered jurisdictions to federal supervision. Rather, the Act by its terms covers any “voting qualification or prerequisite to voting, or standard, practice, or procedure with respect to voting.” 42 U. S. C. § 1973c. A faithful effort to implement the design of the statute must begin by drawing lines between those governmental decisions that involve voting and those that do not.
A simple example shows the inadequacy of the line proffered by appellants and the United States. Under appellants’ view, every time a covered jurisdiction passed a budget that differed from the previous year’s budget it would be [505]*505required to obtain preclearanee. The amount of funds available to an elected official has a profound effect on the power exercised. A vote for an ill-funded official is less valuable than a vote for a well-funded one.
No doubt in recognition of the unacceptable consequences of their views, appellants take the position that while “some budget changes may affect the right to vote and, under particular circumstances, would be subject to preclearance,” most budget changes would not. Postargument Letter from Counsel for Appellants, Nov. 13, 1991 (available in Clerk of Court’s case file). Under their interpretation of §5, however, appellants fail to give any workable standard to determine when preclearance is required. And were we to acknowledge that a budget adjustment is a voting change in even some instances, the likely consequence is that every budget change would be covered, for it is well settled that every voting change with a “potential for discrimination” must be precleared. Dougherty County Bd. of Ed. v. White, 439 U. S., at 42.
Confronting this difficulty, at oral argument the United States suggested that we draw an arbitrary line distinguishing between budget changes and other changes, Tr. of Oral Arg. 21-23. There is no principled basis for the distinction, and it would be a marked departure from the statutory category of voting. If a diminution or increase in an elected official’s powers is a change with respect to voting, then whether it is accomplished through an enactment or a budget shift should not matter. Even if we were willing to draw an unprincipled line excluding budgetary changes but not other changes in an elected official’s decisionmaking authority, the result would expand the coverage of § 5 well beyond the statutory language and the intention of Congress.
Under the view advanced by appellants and the United States, every time a state legislature acts to diminish or increase the power of local officials, preclearance would be required. Governmental action decreasing the power of local [506]*506officials could carry with it a potential for discrimination against those who represent racial minorities at the local level. At the same time, increasing the power of local officials will entail a relative decrease in the power of state officials, and that too could carry with it a potential for discrimination against state officials who represent racial minorities at the state level. The all but limitless minor changes in the allocation of power among officials and the constant adjustments required for the efficient governance of every covered State illustrate the necessity for us to formulate workable rules to confine the coverage of § 5 to its legitimate sphere: voting.
Changes which affect only the distribution of power among officials are not subject to § 5 because such changes have no direct relation to, or impact on, voting. The Etowah County Commission’s Common Fund Resolution was not subject to the preclearance requirement.
We next consider Russell County’s adoption of the Unit System and its concomitant transfer of operations to the county engineer. Of the four categories of changes in rules governing voting we have recognized to date, there is not even an arguable basis for saying that adoption of the Unit System fits within any of the first three. As to the fourth category, it might be argued that the delegation of authority to an appointed official is similar to the replacement of an elected official with an appointed one, the change we held subject to § 5 in Bunton v. Patterson. This approach, however, would ignore the rationale for our holding: “[Ajfter the change, [the citizen] is prohibited from electing an officer formerly subject to the approval of the voters.” Allen, 393 U. S., at 569-570. In short, the change in Bunton v. Patterson involved a rule governing voting not because it effected a change in the relative authority of various governmental [507]*507officials, but because it changed an elective office to an appointive one.
The change in Russell County does not prohibit voters “from electing an officer formerly subject to the[ir] approval.” Allen, supra, at 570. Both before and after the change the citizens of Russell County were able to vote for the members of the Russell County Commission. To be sure, after the 1979 resolution each commissioner exercised less direct authority over road operations, that authority having been delegated to an official answerable to the commission. But as we concluded with respect to Etowah County, the fact that an enactment alters an elected official’s powers does not in itself render the enactment a rule governing voting.
It is a routine part of governmental administration for appointive positions to be created or eliminated and for their powers to be altered. Each time this occurs the relative balance of authority is altered in some way. The making or unmaking of an appointive post often will result in the erosion or accretion of the powers of some official responsible to the electorate, but it does not follow that those changes are covered by § 5. By requiring preclearance of changes with respect to voting, Congress did not mean to subject such routine matters of governance to federal supervision. Were the rule otherwise, neither state nor local governments could exercise power in a responsible manner within a federal system.
The District Court, wrestling with the problem we now face and recognizing the need to draw principled lines, held that Russell County’s adoption of the Unit System is not a covered change because it did not transfer power among officials answerable to different constituencies. Even upon the assumption (the assumption we reject in this case) that some transfers of power among government officials could be changes with respect to voting as that term is used in the Act, we disagree with the District Court’s test. The ques[508]*508tion whether power is shifted among officials answerable to the same or different constituencies is quite distinct from the question whether the power'voters exercise over elected officials is affected. Intraconstituency changes may have a large indirect effect on the voters while interconstituency changes may have a small indirect effect, but in neither case is the effect a change in voting for purposes of the Act. The test adopted by the District Court does not provide the workable rule we seek. In any event, because it proceeds from the faulty premise that reallocations of authority within government can constitute voting changes, we cannot accept its approach.
We need not consider here whether an otherwise uncovered enactment of a jurisdiction subject to the Voting Rights Act might under some circumstances rise to the level of a de facto replacement of an elective office with an appointive one, within the rule of Bunton v. Patterson. For present purposes it suffices to note that the Russell County Commission retains substantial authority, including the power to appoint the county engineer and to set his or her budget. The change at issue in Russell County is not a covered change.
IV
The United States urges that despite our understanding of the language of § 5, we should defer to its administrative construction of the provision. We have recognized that “the construction placed upon the [Voting Rights] Act by the Attorney General ... is entitled to considerable deference.” NAACP v. Hampton County Election Comm’n, 470 U. S., at 178-179. See also United States v. Sheffield Bd. of Comm’rs, 435 U. S. 110, 131 (1978). But the principle has its limits. Deference does not mean acquiescence. As in other contexts in which we defer to an administrative interpretation of a statute, we do so only if Congress has not expressed its intent with respect to the question, and then only if the administrative interpretation is reasonable. See, e. g., Chevron [509]*509U. S. A. Inc. v. Natural Resources Defense Council, Inc., 467 U. S. 837, 842-844 (1984). Because the first of these conditions is not satisfied in the cases before us we do not defer to the Attorney General’s interpretation of the Act.
We do not believe that in its use of the phrase “voting qualification or prerequisite to voting, or standard, practice, or procedure with respect to voting,” 42 U. S. C. § 1973c, the statute is ambiguous as to the question whether § 5 extends beyond changes in rules governing voting. To be sure, reasonable minds may differ as to whether some particular changes in the law of a covered jurisdiction should be classified as changes in rules governing voting. In that sense § 5 leaves a gap for interpretation to fill. See Chevron, supra, at 843. When the Attorney General makes a reasonable argument that a contested change should be classified as a change in a rule governing voting, we can defer to that judgment. But § 6 is unambiguous with respect to the question whether it covers changes other than changes in rules governing voting: It does not. The administrative position in the present cases is not entitled to deference, for it suggests the contrary. The United States argues that the changes are covered by § 5 because they implicate the decisionmak-ing authority of elected officials, even though they are not changes in rules governing voting. This argument does not meet the express requirement of the statute.
V
Nothing we say implies that the conduct at issue in these cases is not actionable under a different remedial scheme. The Voting Rights Act is not an all-purpose antidiscrimination statute. The fact that the intrusive mechanisms of the Act do not apply to other forms of pernicious discrimination does not undermine its utility in combating the specific evils it was designed to address.
Our prior cases hold, and we reaffirm today, that every change in rules governing voting must be precleared. The [510]*510legislative history we rehearsed in South Carolina v. Katzenbach was cited to demonstrate Congress’ concern for the protection of voting rights. Neither the appellants nor the United States has pointed to anything we said there or in the statutes reenacting the Voting Rights Act to suggest that Congress meant other than what it said when it made §5 applicable to changes “with respect to voting” rather than, say, changes “with respect to governance.”
If federalism is to operate as a practical system of governance and not a mere poetic ideal, the States must be allowed both predictability and efficiency in structuring their governments. Constant minor adjustments in the allocation of power among state and local officials serve this elemental purpose.
Covered changes must bear a direct relation to voting itself. That direct relation is absent in both cases now before us. The changes in Etowah and Russell Counties affected only the allocation of power among governmental officials. They had no impact on the substantive question whether a particular office would be elective or the procedural question how an election would be conducted. Neither change involves a new “voting qualification or prerequisite to voting, or standard, practice, or procedure with respect to voting.” 42 U. S. C. § 1973c.
The judgment of the District Court is affirmed.
It is so ordered.
As set forth in 42 U. S. C. § 1973c, § 5 provides:
“Whenever a State or political subdivision with respect to which the prohibitions set forth in section 1973b(a) of this title based upon determinations made under the first sentence of section 1973b(b) of this title are in effect shall enact or seek to administer any voting qualification or prerequisite to voting, or standard, practice, or procedure with respect to voting different from that in force or effect on November 1,1964, or whenever a State or political subdivision with respect to which the prohibitions set forth in section 1973b(a) of this title based upon determinations made under the second sentence of section 1973b(b) of this title are in effect shall enact or seek to administer any voting qualification or prerequisite to voting, or standard, practice, or procedure with respect to voting different from that in force or effect on November 1,1968, or whenever a State or political subdivision with respect to which the prohibitions set forth in section 1973b(a) of this title based upon determinations made under the third sentence of section 1973b(b) of this title are in effect shall enact or seek to administer any voting qualification or prerequisite to voting, or standard, practice, or procedure with respect to voting different from that in force or effect on November 1, 1972, such State or subdivision may institute an action in the United States District Court for the District of Columbia for a declaratory judgment that such qualification, prerequisite, standard, practice, or procedure does not have the purpose and will not [495]*495have the effect of denying or abridging the right to vote on account of race or color, or in contravention of the guarantees set forth in section 1973b(f)(2) of this title, and unless and until the court enters such judgment no person shall be denied the right to vote for failure to comply with such qualification, prerequisite, standard, practice, or procedure: Provided, That such qualification, prerequisite, standard, practice, or procedure may be enforced without such proceeding if the qualification, prerequisite, standard, practice, or procedure has been submitted by the chief legal officer or other appropriate official of such State or subdivision to the Attorney General and the Attorney General has not interposed an objection within sixty days after such submission, or upon good cause shown, to facilitate an expedited approval within sixty days after such submission, the Attorney General has affirmatively indicated that such objection will not be made. Neither an affirmative indication by the Attorney General that no objection will be made, nor the Attorney General's failure to object, nor a declaratory judgment entered under this section shall bar a subsequent action to enjoin enforcement of such qualification, prerequisite, standard, practice, or procedure. In the event the Attorney General affirmatively indicates that no objection will be made within the sixty-day period following receipt of a submission, the Attorney General may reserve the right to reexamine the submission if additional information comes to his attention during the remainder of the sixty-day period which would otherwise require objection in accordance with this section. Any action under this section shall be heard and determined by a court of three judges in accordance with the provisions of section 2284 of title 28 and any appeal shall lie to the Supreme Court."
