Melanie Mason for the LAT on a Ted Olson brief:

Three former California governors are wading in to an Arizona elections case before the Supreme Court that could have major implications on how California draws its congressional and legislative districts.

Former Govs. George Deukmejian, Pete Wilson and Arnold Schwarzenegger, along with the California Chamber of Commerce, GOP mega-donor Charles T. Munger Jr. and entrepreneur Bill Mundell, submitted a brief late Friday stating their support for an independent commission that crafts a state’s districts, rather than restricting the task to state legislatures.
