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 сommission members, but requires that a member be elected from each of four residency districts. 2 Ap *478 pellees’ constitutional 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
After extensive discоvery, 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,
,“[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.” Jurisdictionаl Statement 15-16.
The Court of Appeals for the Fifth Circuit considered the case en banc and reversed, 8-6.

Dusch
reaffirmed the principle enunciated in
Fortson
v.
Dorsey,
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 opiniоn noted: “If a borough’s resident on the council represented in fact only the borough, . . . different conclusions might follow.”
“ ‘As the plan becomes effective, if it then opеrates 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.
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 аn identifiable element of the voting population. Rather than basing its decision on a factual con *481 elusion 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 elеctorate which chooses them. But that is precisely the proposition rejected in Dusch.
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.
It is so ordered.
Notes
Act No. 328, § 6, Acts of Alabama (Feb. 8, 1901) (as amended). Our appellate jurisdiction is based on 28 U. S. C. §1254(2).
The Judge of Probate of Dallas County is ex officio chairman of the commission, and votes in the casе of a tie vote among the *478 commissioners. He is elected by countywide ballot and may reside anywhere within the county.
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
Judge Bell concurred in part and dissented in part. Hе would have remanded to the District Court for an evidentiary hearing on the question of invidious discrimination.
In fashioning this distinction of
Dusch,
the Fifth Circuit relied on a prior deсision of a panel of that court,
Keller
v.
Gilliam,
Given the populations of the four residence distriсts, 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, thе 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 majоrity of the county’s population. Nor is it possible in any other fashion to obtain a majority of the commission without the votes of eithеr 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 ease, but they do seem to be inconsistent with the rationale on which the Court of Appeals based its decision.
