Costco is opposing a proposal to centralize at least 25 customer lawsuits seeking refunds related to tariffs. The company and other retailers argue that the cases involve materially different pricing decisions and contractual arrangements, including sensitive trade secrets. They contend that separate proceedings are more appropriate because some lawsuits are nearing decisions and centralized multidistrict litigation would not improve efficiency.
