Two candidates and two voters from the Green and Libertarian parties are seeking to intervene on the side of the plaintiffs in Chamness v. Bowen, one of three lawsuits pending against California's top two open primary system. In their motion to intervene, filed with the Ninth Circuit Court of Appeals earlier this month, the Greens and Libertarians argue that unless the top two primary system is struck down, they will be deprived of their rights to participate in the June primary election (of their respective parties), as well as the November general election.
