Ronald Sadler, a California resident, owned a helicopter distribution company in West Germany, Delta Avia. This company distributed U.S.-made Hughes civilian helicopters in western Europe. Sadler’s German firm purchased 85 helicopters from Hughes Aircraft Co. After export licenses were obtained in reliance on the purchaser’s written assurance that the goods would not be disposed of contrary to the export license, the helicopters were exported to Germany for resale in western Europe. Thereafter, Delta Avia exported them to North Korea, which was a country subject to a trade embargo by the United States. The helicopters were converted to military use. Sadler was charged with violating the Export Administration Regulations. In Sadler’s defense, it was contended that the U.S. regulations have no effect on what occurs in the resale of civilian helicopters in another sovereign country. Decide.
