Cars in which liquor was imported were seized by the government. The operators were prosecuted for violation of the customs laws, and the government attempted to declare forfeiture of the cars under the customs laws. Lienors whose rights are not recognized under these laws intervened and claimed that forfeiture could be declared only under the National Prohibition Act which saves the rights of lienors. Held, in General Motors Acceptance Corp. v. United States, that forfeiture may be declared either under customs laws or the National Prohibition Act.
