Back on November 27, 2006, a U.S. District Court in Cincinnati struck down an Ohio law that made it illegal for circulators to be paid per signature. That decision is now reported. Citizens for Tax Reform v Deters, 462 F Supp 2d 827 (S.D. Ohio, 2006).
When a decision is reported, it is more influential. This decision is particularly well-reasoned, and it will help, as activists try to stop bills to outlaw paying circulators per signature now pending in the Washington and Montana legislatures.
