Tim Eyman announces lawsuit to let $30 car tab measure take effect

OLYMPIA, Wash. — There's a new legal front in the battle over $30 car tabs.

But will it be successful in time to cut car tab taxes as scheduled Thursday?

Supporters are anxious to get rid of car tab bills that can run into the hundreds of dollars.

Opponents want to preserve the car tab money that goes to roads and transit.

The new legal action was filed in person Tuesday at the state Supreme Court by lawyer Steve Pidgeon.

It asks the high court to take over jurisdiction of the case.

It comes from eastern Washington residents upset that $30 car tabs have been put on hold by a King County judge until it's decided whether I-976 is unconstitutional.

They are "voters who voted in favor of I-976, who quite frankly feel outraged about the idea that King County would bring a lawsuit in King County to be heard by a King County judge who would then rule in favor of King County," Pidgeon told reporters on the steps of the Temple of Justice in Olympia.

Initiative sponsor Tim Eyman is not an official part of this particular legal action, but he supports it. He appeared at the Supreme Court on Tuesday to support this strategy.

State Attorney General Bob Ferguson is suing Eyman for campaign finance fraud.

In a statement, he called Eyman a candidate for governor looking for headlines.

We'll let you know what the Supreme Court decides and whether $30 car tabs will start Thursday as scheduled.
