On August 16, the Nevada Green Party filed a lawsuit against the June 3 petition deadline for petitions for unqualified parties to submit their signatures. On August 26, U.S. District Court Judge Jennifer Dorsey, an Obama appointee, moved the hearing from August 31 to August 29. That hearing was held. See this newspaper story about the hearing. Three Democratic voters intervened in the case on the side of the state, saying they would be injured if Jill Stein gets on the ballot. The case is Nevada Green Party v Cegavske, 2:16cv-1951. An opinion is expected soon.
The basis for the lawsuit is that in 1992, a U.S. District Court had enjoined the deadline, which was June 10 back then. The legislature had moved the deadline to July the following year. But over the years, the legislature forgot why it had done that, and moved it back to April, and then in 2015 moved it to early June.
