Elec. Code, § 14028

(a) A violation of Section 14027 is established if it is shown that racially polarized voting occurs in elections for members of the governing body of the political subdivision or in elections incorporating other electoral choices by the voters of the political subdivision. Elections conducted prior to the filing of an action pursuant to Section 14027 and this section are more probative to establish the existence of racially polarized voting than elections conducted after the filing of the action.

(b) The occurrence of racially polarized voting shall be determined from examining results of elections in which at least one candidate is a member of a protected class or elections involving ballot measures, or other electoral choices that affect the rights and privileges of members of a protected class. One circumstance that may be considered in determining a violation of Section 14027 and this section is the extent to which candidates who are members of a protected class and who are preferred by voters of the protected class, as determined by an analysis of voting behavior, have been elected to the governing body of a political subdivision that is the subject of an action based on Section 14027 and this section. In multiseat at-large election districts, where the number of candidates who are members of a protected class is fewer than the number of seats available, the relative groupwide support received by candidates from members of a protected class shall be the basis for the racial polarization analysis.

(c) The fact that members of a protected class are not geographically compact or concentrated may not preclude a finding of racially polarized voting, or a violation of Section 14027 and this section, but may be a factor in determining an appropriate remedy.

(d) Proof of an intent on the part of the voters or elected officials to discriminate against a protected class is not required.

(e) Other factors such as the history of discrimination, the use of electoral devices or other voting practices or procedures that may enhance the dilutive effects of at-large elections, denial of access to those processes determining which groups of candidates will receive financial or other support in a given election, the extent to which members of a protected class bear the effects of past discrimination in areas such as education, employment, and health, which hinder their ability to participate effectively in the political process, and the use of overt or subtle racial appeals in political campaigns are probative, but not necessary factors to establish a violation of Section 14027 and this section.
