On January 22, the Democratic and Republican Parties of Washington state each filed amended complaints in the case challenging the constitutionality of the “top-two open primary” that the voters passed in 2004. The case is Washington State Republican Party v State, cv05-927. Here is the Republican Party’s amended complaint. Here is the Democratic Party’s amended complaint. Thanks to Thomas Jones for the latter.
The U.S. Supreme Court ruled in March 2008, in this very same lawsuit, that “top-two” is not unconstitutional on its face, as to the freedom of association argument, but said it might be unconstitutional as applied. Newspapers in California and Washington have failed to communicate this information to their readers. They constantly say that the U.S. Supreme Court upheld the law.
