Short title-Purposes-1983 c 288: "This act may be cited as the antitrust/consumer protection improvements act. Its purposes are to strengthen public and private enforcement of the unfair business practices-consumer protection act, chapter 19.86 RCW, and to repeal the unfair practices act, chapter 19.90 RCW, in order to eliminate a statute which is unnecessary in light of the provisions and remedies of chapter 19.86 RCW. In repealing chapter 19.90 RCW, it is the intent of the legislature that chapter 19.86 RCW should continue to provide appropriate remedies for predatory pricing and other pricing practices which constitute violations of federal antitrust law."
