The Arizona Libertarian Party has filed this 66-page opening brief in Libertarian Party of Arizona v Reagan, 17-16491. The case concerns the requirements for getting on the primary ballot of a small qualified party. The state sets different rules for parties that have been continuously qualified, versus parties that got on the ballot at either of the last two elections. As a result, the ballot-qualified Libertarian Party, which is subject to the harsh rules, was unable to run any candidates for Congress or state legislature in 2016, whereas the ballot-qualified Green Party, which is subject to extremely easy rules, was able to run such candidates. Yet the Libertarian Party in Arizona is larger than the Green Party in Arizona.
