REESE et al. No. 74—1077. May 19, 1975. PER CURIAM. 1 Appellees are residents of the city of Selma, Ala., who brought this action to challenge the system by which members of the Dallas County, Ala., Commission are elected. The system, which is established by a state statute,1 provides for countywide balloting for each of the four commission members, but requires that a member be elected from each of four residency districts.2 Appellees' sconstitutional claim was premised on the fact that the populations of the four districts vary widely, with the result that only one resident of the city of Selma can be a member of the commission, although the city contains about one-half of the county's population.3 2 After extensive discovery, the United States District Court for the Southern District of Alabama entered summary judgment for appellants, Dallas County and the members of the Dallas County Commission. The court relied heavily on our decision in Dusch v. Davis, 387 U.S. 112, 87 S.Ct. 1554, 18 L.Ed.2d 656 (1967), and concluded: 3 '(T)he fundamental principle of representative government has been fulfilled in that each County Commissioner's tenure depends upon the vote of the qualified voters from the countywide electorate. This fact alone requires each County Commissioner to represent the county and not his own residential area.' Jurisdictional Statement 15—16. 4 The Court of Appeals for the Fifth Circuit considered the case en banc and reversed, 8—6,4 505 F.2d 879 (1974). The majority concluded that the unequal residency districts diluted the votes of city residents, and that the resulting discrimination was invidious. It distinguished Dusch on the basis of the particular facts of that case, which involved seven council membersselected from unequal residency boroughs, and four council members who could live anywhere in the city; according to the Court of Appeals, the effect was to assure that a majority of the 11-man council could not be assembled without the cooperation of either one 'representative' of the heavily populated boroughs or of one member of unrestricted residency. In the present case, on the other hand, the structure of the commission is such that the three commissioners who reside outside of Selma can control the commission, even though they 'represent' only a slight majority of the population.5 The dissenters in the Court of Appeals thought that Dusch controlled. We agree, and reverse the Court of Appeals. 5 Dusch reaffirmed the principle enunciated in Fortson v. Dorsey, 379 U.S. 433, 438, 85 S.Ct. 498, 501, 13 L.Ed.2d 401, 404 (1965), that when an official's 'tenure depends upon the countywide electorate he must be vigilant to serve the interests of all the people in the county, and not merely those of people in his home district.' Because the districts in the present plan are used 'merely as the basis of residence for candidates, not for voting or representation,' ibid.; Dusch v. Davis, supra, 387 U.S., at 115, 87 S.Ct., at 1556, each commissioner represents the citizens of the entire county and not merely those of the district in which he resides. We think that this teaching of Dusch and of Fortson v. Dorsey was all but ignored by the Court of Appeals, which chose instead to focus on a factual element of Dusch which was accorded absolutely no significance in the opinion in that case. Nor do we understand what significance could be attached to the presence of council members subject to no residence requirement, given the basic teaching that elected officials represent all of those who elect them, and not merely those who are their neighbors. 6 The Court of Appeals was, of course, correct in recognizing that Dusch does not entirely insulate a plan such as this from constitutional attack. As that opinion noted: 'If a borough's resident on the council represented in fact only the borough, . . . different conclusions might follow.' 387 U.S., at 116, 87 S.Ct., at 1556. Similarly, in Dusch we approvingly quoted a portion of the District Court's opinion, including the following passage: 7 "As the plan becomes effective, if it then operates to minimize or cancel out the voting strength of racial or political elements of the voting population, it will be time enough to consider whether the system still passes constitutional muster." Id., at 117, 87 S.Ct., at 1556. 8 We think it clear, however, that Dusch contemplated that a successful attack raising such a constitutional question must be based on findings in a particular case that a plan in fact operates impermissibly to dilute the voting strength of an identifiable element of the voting population. Rather than basing its decision on a factual conclusion of this sort, the Court of Appeals relied on a theoretical presumption to reach its determination that residents of Selma were victims of invidious discrimination. That theoretical presumption is that elected officials will represent the districts in which they reside rather than the electorate which chooses them. But that is precisely the proposition rejected in Dusch. 9 For the foregoing reasons, the judgment of the Court of Appeals must be reversed, and the cause is remanded for further proceedings not inconsistent with this opinion. 10 It is so ordered. 11 Reversed and remanded. 12 Mr. Justice DOUGLAS took no part in the consideration or decision of this case. 1 Act No. 328, § 6, Acts of Alabama (Feb. 8, 1901) (as amended). Our appellate jurisdiction is based on 28 U.S.C. § 1254(2). 2 The Judge of Probate of Dallas County is ex officio chairman of the commission, and votes in the case of a tie vote among the commissioners. He is elected by countywide ballot and may reside anywhere within the county. 3 As shown by the 1970 official census, the population of each of the residency districts is as follows: City of Selma....... 27,379 West................. 6,209 South............... 14,203 Fork................. 7,505 4 Judge Bell concurred in part and dissented in part. He would have remanded to the District Court for an evidentiary hearing on the question of invidious discrimination. 5 In fashioning this distinction of Dusch, the Fifth Circuit relied on a prior decision of a panel of that court, Keller v. Gilliam, 454 F.2d 55 (1972). According to the Court of Appeals, and for the reasons stated in the text, '(i)n Keller, as in the present case, preserving majority rule was not possible, and the plan was struck down.' 505 F.2d 879, 885 (1974). Given the populations of the four residence districts, see n. 3, supra, it is difficult to understand how the Fifth Circuit's distinction of Dusch is applicable even to the facts of this case. According to the 1970 census, the city district has a population of 27,379, while the three rural districts have a combined population of 27,917. Thus should the commissioners who reside in the rural districts vote together, their control of the commission does in fact reflect their 'representation' of a majority of the county's population. Nor is it possible in any other fashion to obtain a majority of the commission without the votes of either commissioners 'representing' a majority of the county's population or of the Judge of Probate whose residency is unrestricted. These facts have no bearing on our disposition of this case, but they do seem to be inconsistent with the rationale on which the Court of Appeals based its decision.
