Unanimous 9-0. Narrow issue.

Here’s how we described the case in a “The Week” entry:

Mar. 16 2006-In yet another in the seemingly ceaseless series of rearguard efforts to compel non-members to pay to support the political activities of unions, the Washington supreme court rules 6-3 that a state statute that requires non-members to “opt in” if they want to pay to support the union’s political activities (rather than to “opt out” if they don’t) somehow violates the union’s First Amendment rights. That ruling is now under review by the U.S. Supreme Court, with a decision due by the end of June 2007.

Looks like the Supreme Court has unanimously rejected another in the seemingly ceaseless series of rearguard efforts to compel non-members to pay to support the political activities of unions.
