(Seattle, WA)  --  A King County Superior Court judge says Initiative 1366 violates the Washington State Constitution.  The initiative gives state lawmakers a choice between changing the constitution to make it harder to raise taxes or cutting the state sales tax.  Judge William Downing describes I-1366 as a thinly-veiled effort to pass an amendment to the state  constitution, which is something the state Supreme Court has said can't be accomplished through an initiative.  The "Spokesman-Review" reports that Tim Eyman, an anti-tax activist who spearheaded the initiative, was testifying before a Senate committee yesterday on a possible constitutional amendment that would comply with I-1366, when Downing's decision was announced.
