What follows is an opinion from the Supreme Court of the United States. Your task is to determine the bases on which the Supreme Court rested its decision with regard to the legal provision that the Court considered in the case. Consider "judicial review (national level)" if the majority determined the constitutionality of some action taken by some unit or official of the federal government, including an interstate compact. Consider "judicial review (state level)" if the majority determined the constitutionality of some action taken by some unit or official of a state or local government. Consider "statutory construction" for cases where the majority interpret a federal statute, treaty, or court rule; if the Court interprets a federal statute governing the powers or jurisdiction of a federal court; if the Court construes a state law as incompatible with a federal law; or if an administrative official interprets a federal statute. Do not consider "statutory construction" where an administrative agency or official acts "pursuant to" a statute, unless the Court interprets the statute to determine if administrative action is proper. Consider "interpretation of administrative regulation or rule, or executive order" if the majority treats federal administrative action in arriving at its decision.Consider "diversity jurisdiction" if the majority said in approximately so many words that under its diversity jurisdiction it is interpreting state law. Consider "federal common law" if the majority indicate that it used a judge-made "doctrine" or "rule; if the Court without more merely specifies the disposition the Court has made of the case and cites one or more of its own previously decided cases unless the citation is qualified by the word "see."; if the case concerns admiralty or maritime law, or some other aspect of the law of nations other than a treaty; if the case concerns the retroactive application of a constitutional provision or a previous decision of the Court; if the case concerns an exclusionary rule, the harmless error rule (though not the statute), the abstention doctrine, comity, res judicata, or collateral estoppel; or if the case concerns a "rule" or "doctrine" that is not specified as related to or connected with a constitutional or statutory provision. Consider "Supreme Court supervision of lower federal or state courts or original jurisdiction" otherwise (i.e., the residual code); for issues pertaining to non-statutorily based Judicial Power topics; for cases arising under the Court's original jurisdiction; in cases in which the Court denied or dismissed the petition for review or where the decision of a lower court is affirmed by a tie vote; or in workers' compensation litigation involving statutory interpretation and, in addition, a discussion of jury determination and/or the sufficiency of the evidence.

Opinion:
FOREMAN et al. v. DALLAS COUNTY, TEXAS, et al.
No. 96-987.
Decided June 27, 1997
Together with No. 96-1389, Foreman et al. v. Dallas County, Texas, et al., also on appeal from the same court.
Per Curiam.
Texas by statute authorizes counties to appoint election judges, one for each precinct, who supervise voting at the polls on election days. In 1988 and several times thereafter, Dallas County changed its procedures for selecting these officials. Each of the new methods used party-affiliation formulas of one sort or another. After the most recent change in 1996, appellants sued the county and others in the United States District Court, claiming that § 6 of the Voting Rights Act of 1965, 79 Stat. 439, as amended, 42 U. S. C. § 1973c, required that the changes be precleared.
A three-judge court held that preclearance was not required because the county was simply exercising, under the state statute, its “discretion to adjust [the procedure for appointing election judges] according to party power.” App. to Juris. Statement 4a. The court apparently concluded that this “discretionary” use of political power meant that the various methods for selecting election judges were not covered changes under § 5. The court also concluded that the Justice Department’s preclearance of a 1985 submission from the State — the recodification of its entire election code — operated to preclear the county’s use of partisan considerations in selecting election judges. The court denied injunctive relief, and later dismissed appellants’ complaint pursuant to Federal Rule of Civil Procedure 12(b)(6). Appellants have brought both of these rulings here.
We believe that the decision of the District Court is inconsistent with our precedents. First, in NAACP v. Hampton County Election Comm’n, 470 U. S. 166, 178 (1985), we held that even “an administrative effort to comply with a statute that had already received clearance” may require separate preclearance, because § 5 “reaches informal as well as formal changes.” Thus, the fact that the county here was exercising its “discretion” pursuant to a state statute does not shield its actions from § 5. The question is simply whether the county, by its actions, whether taken pursuant to a statute or not, “enact[ed] or [sought] to administer any ... standard, practice, or procedure with respect to voting different from” the one in place on November 1, 1972. § 5. The fact that the county’s new procedures used political party affiliation as the selection criterion does not mean that the methods were exempt from preclearance.
Second, the State’s 1985 submission (the recodification and a 30-page summary of changes to the old law) indicated that the only change being made to the statute concerning election judges was a change to “the beginning date and duration of [their] appointment.” Thus, neither the recodified statute nor the State’s explanations said anything about the use of specific, partisan-affiliation methods for selecting election judges. This submission was clearly insufficient under our precedents to put the Justice Department on notice that the State was seeking preclearance of the use of partisan affiliations in selecting election judges. See, e.g., Young v. Fordice, 520 U. S. 273, 286-287 (1997); Lopez v. Monterey County, 519 U. S. 9, 15 (1996); Clark v. Roemer, 500 U. S. 646, 658-659 (1991).
Because the parties agree that the record is silent as to the procedure used by Dallas County for appointing election judges as of November 1,1972, the date on which Texas became a covered jurisdiction under the Voting Rights Act, we cannot make a final determination here as to whether pre-clearance is in fact required. We therefore vacate the judgment of the District Court in No. 96-1389, dismiss the appeal from the District Court’s interlocutory judgment in No. 96-987, see Shaffer v. Carter, 252 U. S. 37, 44 (1920), and remand the cases for further proceedings.
It is so ordered.
