"On February 25, the Arizona Green Party filed a federal lawsuit against the February 27 petition deadline for newly-qualifying parties. The case is Arizona Green Party v Bennett, 2:14cv-375.
There are no reported precedents that have ever upheld a petition deadline for a newly-qualifying party earlier than April. The Arizona Green Party has been working very hard on its petition to get back on the ballot, but it needs another few weeks to finish. The requirement is 23,041 valid signatures.
