Defense or action of usury — Limitations.

No person may plead the defense of usury or maintain any action thereon based upon a transaction heretofore entered into if such transaction:

(1) Constitutes a "consumer lease" as defined in RCW 63.10.020; or

(2) Would constitute such a consumer lease but for the fact that:

(i) The lessee was not a natural person;

(ii) The lease was not primarily for personal, family, or household purposes; or

(iii) The total contractual obligation exceeded twenty-five thousand dollars.
