Since passage of the Voting Rights Act of 1965 and lessening of some historic barriers to voter registration and voting, legal challenges have been made based on at-large election schemes at the county or city level, including in school board elections, in numerous jurisdictions where minorities had been effectively excluded from representation on local councils or boards. An example is Charleston County, South Carolina, which was sued in 2001 and reached a settlement in 2004. Its county commission changed to nine members elected from single-member districts; in 2015 they included six white Republicans and three African-American Democrats, where the black minority makes up more than one-third of the population.
