On August 12, the Nevada Secretary of State said that the Green Party petition, which had been handed in on the June 3 deadline, did not have enough valid signatures. Clark County (where most of the signatures had been obtained) had made a similar ruling in late June. It is possible the Green Party will sue to overturn the June 3 petition deadline. The party submitted 1,200 more signatures after that deadline.

In 1992 a U.S. District Court had enjoined the deadline that was in effect back then, which was June 10. The legislature had then moved the deadline from June to July. But years later, the legislature move it to April, and then last year moved it to June.
