Wash. Rev. Code § 46.70.190
Any person who is injured in his or her business or property by a violation of this chapter, or any person so injured because he or she refuses to accede to a proposal for an arrangement which, if consummated, would be in violation of this chapter, may bring a civil action in the superior court to enjoin further violations, to recover the actual damages sustained by him or her together with the costs of the suit, including a reasonable attorney's fee.
If a new motor vehicle dealer recovers a judgment or has a claim dismissed with prejudice against a manufacturer under RCW 46.96.040 or 46.96.050(3) or this section, the new motor vehicle dealer is precluded from pursuing that same claim or recovering judgment for that same claim against the same manufacturer under the federal Automobile Dealer Franchise Act, 15 U.S.C. Sections 1221 through 1225, but only to the extent that the damages recovered by or denied to the new motor vehicle dealer are the same as the damages being sought under the federal Automobile Dealer Franchise Act. Likewise, if a new motor vehicle dealer recovers a judgment or has a claim dismissed with prejudice against a manufacturer under the federal Automobile Dealer Franchise Act, the dealer is precluded from pursuing that same claim or recovering judgment for that same claim against the same manufacturer under this chapter, but only to the extent that the damages recovered by or denied to the dealer are the same as the damages being sought under this chapter.
A civil action brought in the superior court pursuant to the provisions of this section must be filed no later than one year following the alleged violation of this chapter.
