In Go2Net, Inc. v. Freeyellow.com, Inc., 143 P.3d 590, 593,11 (Wash. 2006) the Washington Supreme Court held that waiver and estoppel were unavailable because the Securities Act of Washington was intended to deter wrongdoing and because the statutes therein specifically set forth some defenses but did not mention estoppel and waiver. The court pointed to statutes providing a reasonable care defense to control-persons of liable entities, imposing a statute of limitations for private civil actions, eliminating liability for defendants who made written rescission offers, providing a good-faith defense, and voiding contract provisions purporting to waive compliance with the Act.
