This may get interesting.  Hispanic citizens in filed a lawsuit challenging at-large elections in Compton, California.  Section 2 of the Voting Rights Act is usually used by plaintiffs who are part of a national racial minority against an election law, such as at large elections, which result in an all-white or mostly all white governing body. 

Compton’s plaintiffs are challenging an all black governing body.  The case is being brought under a California version of the Voting Rights Act.
