Last year, the Arizona Libertarian and Green Parties filed a federal lawsuit against a new Arizona law that said only the two largest parties should be listed on the voter registration form. Voters who wanted to register into any other party had to write-in the name of the party on a very small blank line.
The case had been slowed by the state’s request for discovery, but the discovery period has now ended. The briefs are due June 11. The case is Arizona Libertarian Party v Bennett, 4:11cv-856.
