OLYMPIA, Wash. (AP) — A Thurston County judge has overturned a Washington state rule that prohibits insurers from using credit scoring to set rates for auto, homeowner and renter insurance. Insurance Commissioner Mike Kreidler adopted the rule in February and immediately drew a legal challenge from insurer groups. The rule, which was set to take effect March 4, was paused while the legal proceedings continued. In her oral ruling invalidating the rule, Thurston County Superior Court Judge Indu Thomas said that Kreidler exceeded his statutory authority. Kreidler spokeswoman Stephanie Marquis said in an email that a written ruling from the court wasn’t expected until next week and that the office was still weighing whether to appeal.
