In the case of United States v. Guy W. Capps, Inc., 1954, the U.S Supreme Court ruled in favor of the government and held that imported goods could be subject to seizure if they were not properly marked with their country of origin as required by customs law. The defendant, Guy W. Capps Inc., had imported a shipment of Scotch whisky from Canada which was originally produced in Scotland but bottled in Canada without any indication on its labels about its Scottish origin or Canadian bottling process. The court found this to be a violation of Section 304(a) Tariff Act (1930), which requires every article manufactured abroad and brought into America for sale must be marked with English name indicating its country-of-origin so that ultimate purchasers may know where it is made before purchasing it.

In the dissenting opinion for United States v. Guy W. Capps, Inc., it was argued that the majority's decision to allow a private party to challenge an import license issued by the President under Section 402 of the Mutual Security Act of 1954 was incorrect. The dissenters believed this interpretation undermined executive power and discretion in foreign affairs as granted by Congress, which could have significant implications on international relations and trade agreements. They also pointed out that there were no clear guidelines or standards provided in the Act for courts to review such decisions made by the President or his delegates regarding import licenses, suggesting judicial overreach into administrative matters best left with elected officials who are more accountable to public sentiment and national interests than judges.
