Elec. Code, § 14026

As used in this chapter:

(a) “At-large method of election” means any of the following methods of electing members to the governing body of a political subdivision:

(1) One in which the voters of the entire jurisdiction elect the members to the governing body.

(2) One in which the candidates are required to reside within given areas of the jurisdiction and the voters of the entire jurisdiction elect the members to the governing body.

(3) One that combines at-large elections with district-based elections.

(b) “District-based elections” means a method of electing members to the governing body of a political subdivision in which the candidate must reside within an election district that is a divisible part of the political subdivision and is elected only by voters residing within that election district.

(c) “Political subdivision” means a geographic area of representation created for the provision of government services, including, but not limited to, a general law city, general law county, charter city, charter county, charter city and county, school district, community college district, or other district organized pursuant to state law.

(d) “Protected class” means a class of voters who are members of a race, color, or language minority group, as this class is referenced and defined in the federal Voting Rights Act of 1965 (52 U.S.C. Sec. 10301 et seq.).

(e) “Racially polarized voting” means voting in which there is a difference, as defined in case law regarding enforcement of the federal Voting Rights Act of 1965 (52 U.S.C. Sec. 10301 et seq.), in the choice of candidates or other electoral choices that are preferred by voters in a protected class, and in the choice of candidates and electoral choices that are preferred by voters in the rest of the electorate. The methodologies for estimating group voting behavior as approved in applicable federal cases to enforce the federal Voting Rights Act of 1965 (52 U.S.C. Sec. 10301 et seq.) to establish racially polarized voting may be used for purposes of this section to prove that elections are characterized by racially polarized voting.
