The 9th circuit is likely to hear Nader v Brewer in October 2007. This is the case over whether Arizona’s early June petition deadline is too early for independent presidential candidates, and whether it is unconstitutional for a state to ban out-of-state petitioners for independent presidential candidates.
Other 2004 Nader ballot access cases that are still pending are in Ohio (over whether the state may require circulators to be registered voters), and in Hawaii (over whether the state’s petition-checking procedures violate due process, and also over whether it is constitutional for a state to require 6 times as many signatures for an independent presidential candidate as for an entire new party).
