SEATTLE (AP) — The Washington Supreme Court has upheld vehicle registration tax increases in the Puget Sound area, a decision that preserves billions of dollars in voter-approved money earmarked for light trail and other projects. Seven people filed the lawsuit to overturn a rate increase by Sound Transit. Voters in 2016 approved the rate hike to fund the Sound Transit 3 expansion project. The lawsuit sought a refund of millions of dollars in car registration fees collected through the increase to help pay for the $54 billion expansion. In a 7 to 2 decision Thursday the high court justices found that the motor vehicle excise tax was constitutional.
