On May 12, the Montana Republican Party voluntarily withdrew part of its lawsuit concerning the Montana open primary. The party had asked the Ninth Circuit to rule that the state cannot force the party to elect local party officers in an open primary. The recent Republican Party notice to the Ninth Circuit says, “On May 5, 2015, Montana Governor Steve Bullock signed into law HB 454, which allows political parties to establish their own rules regarding the selection of their internal leaders. Appellants’ preliminary injunction appeal is therefore moot.”
However, the part of the case over whether the party can be forced to let members of other parties vote in its primaries for public office is still alive in the U.S. District Court.
