(1) No suit or proceeding shall be maintained in any court for the recovery of any amount alleged to have been overpaid under RCW 82.38.180 unless a claim for refund or credit has been duly filed pursuant to RCW 82.38.190.

(2) Within ninety days after the mailing of the notice of the department's action upon a claim filed pursuant to RCW 82.38.190, the claimant may bring an action against the department on the grounds set forth in the claim in a court of competent jurisdiction in Thurston county for the recovery of the whole or any part of the amount with respect to which the claim has been disallowed. Failure to bring action within the time specified constitutes a waiver of any demand against the state on account of the alleged overpayments.

(3) If the department fails to mail notice of action on a claim within six months after the claim is filed, the claimant may, prior to the mailing of notice by the department of its intention on the claim, consider the claim disallowed and bring an action against the department, on the grounds set forth in the claim for the recovery of the whole or any part of the amount claimed as an overpayment.
