On September 29, 2006, Ralph Nader filed a lawsuit against Ohio’s law that requires circulators to be registered voters. The Ohio law on this subject is clearly unconstitutional, because in 1999 the U.S. Supreme Court had ruled that states cannot require initiative circulators to be registered voters. Nader v Blackwell, 2:06cv821. The case is not moot because Nader (who was injured by this law in 2004) is suing for damages (of $1).
An earlier lawsuit filed by Nader supporters in 2004 did not ever get a substantive ruling, because the judge refused to rule, on the grounds that some of Nader’s circulators had been deceptive about their domicile.
