A U.S. District Court will hear arguments in Montana Green Party v Stapleton, 6:18cv-87, on Thursday, December 11, in Great Falls. This is the case that challenges the unequal distribution requirement for the party petition, and also the March petition deadline. The case arose in 2018, when the Green Party had enough valid signatures statewide on its party petition, but in a few districts did not meet the distribution requirement.
The distribution requirement requires a certain number of signatures in each of 34 of the 100 State House districts. But, oddly, in some districts the number of signatures is as low as 55, while in others it is as high as 150. The Green Party argues that the law, by requiring unequal number of signatures in various districts (even though the districts are of approximate equal population), violates one-person, one-vote.
Here is the last brief, filed by the Green Party on October 25. UPDATE: the original post said the hearing would be December 5, but it has been moved to December 11.
