The Short Version
This claim is false. The Supreme Court ruled that IEEPA did not authorize Trump's tariffs, but it did not address refunds at all—it remanded those questions to the Court of International Trade. Any potential refund claims would be filed by importers through customs processes, not paid directly to consumers. There is no legal requirement that consumers receive refunds for higher prices. Some companies like FedEx have voluntarily pledged to pass refunds through, but that is a business decision, not a court mandate.
