On August 14, U.S. District Court Judge Stanley R. Chesler upheld New Jersey’s closed primary system, in Balsam v Guadagno, 14-1388. Here is the twelve-page decision. The decision came down only one day after plaintiffs’ last brief had been filed.
The plaintiffs had not said anything about how independent candidates and the nominees of unqualified parties get on the general election ballot. However, the judge made reference to that subject, and said, accurately, that it is relatively easy (New Jersey only requires 800 signatures for such candidates to get on the ballot for statewide office, and never more than 100 signatures for other office) Thanks to Rick Hasen for the link.
UPDATE: here is an article about the decision by Shawn Griffiths. It says the plaintiffs will appeal to the Third Circuit.
