The California State Court of Appeals will hold oral arguments in Field v Bowen in San Francisco on September 12 at 9 a.m. This is one of the two cases that challenges two particular details of the Proposition 14 “top-two” system: (1) that some candidates may show a party label on the ballot and others may not; (2) that write-in space is printed on general election ballots but write-ins for Congress and state office may never be counted.
There is a similar lawsuit, with different plaintiffs, in federal court as well. That case is called Chamness v Bowen. That case has an oral argument on August 22 in Los Angeles.
