On September 2, a Washington state Superior Court rejected a lawsuit brought to settle the validity of the Referendum-71 petition. The court said such a case can only be filed 5 days after the Secretary of State has certified a petition, and must be filed in Olympia, not Seattle. Here is the 9-page decision. The case will be refiled in Olympia next week.
The issues are whether circulators must sign each petition sheet; and whether voters must be registered at the time they sign the petition or whether they can register later (but before the petitions are checked).
