On October 18, the South Dakota Constitution Party filed this opening brief in the 8th circuit.  The only issue in the case is the state’s ban on out-of-state circulators.  The case is Constitution Party of South Dakota v Nelson.  The party is not appealing the other part of the case, on the South Dakota law that says members of some ballot-qualified parties must submit 250 signatures of party members in order to be on the party’s primary ballot for statewide office.
