TACOMA, Wash. (AP) — The Latest on the car-tab lawsuit in Pierce County court (all times local):

12:20 p.m.

A Pierce County judge has dismissed a lawsuit claiming that Sound Transit was unconstitutionally collecting increased car-tab fees to pay for its mass transit expansion.

In her ruling Friday, Pierce County Judge Kathryn Nelson sided with the regional transit agency and found that the 2015 law that put the Sound Transit 3 transportation package on the ballot was constitutional.

KOMO reports that the judge's ruling means that work on the light rail expansion can continue.

Seven Puget Sound residents had argued in a class-action lawsuit that the 2015 law violated the constitution because it did not include the full text of the statute it was amending.

The plaintiffs wanted Sound Transit to refund $400 million it says was improperly collected from motorists.

A judge in Pierce County is hearing arguments Friday in a lawsuit that alleges Sound Transit is unconstitutionally collecting car-tab fees to pay for mass transit expansion.

Seven Seattle-area residents sued the agency in June, challenging the collection of higher vehicle license fees that voters approved as part of the Sound Transit 3 transportation package in 2016.

The lawsuit argues that the 2015 law that put the Sound Transit 3 transportation package on the ballot is unconstitutional because it amends existing statute without including the full text.

A judge is deciding Friday whether to grant the plaintiffs' motion for summary judgment.

Sound Transit spokesman Geoff Patrick tells KOMO that the agency is confident in the validity of the law.
