After reading attractive brochures advertising a package tour of the Dominican Republic, a U.S. family decided to purchase tickets for the family vacation plan. The tour was a product of four different business entities, two domestic (U.S.) and two foreign. Sheraton Hotels & Inns, World Corporation, was to provide food and lodging; Dominicana Airlines, wholly owned by the government of the Dominican Republic, which routinely flew into Miami International Airport and sold tickets within the United States, was to provide round-trip air transportation and ‘‘tourist cards’’ necessary for entry into the Dominican Republic; and two U.S. firms organized and sold the tour. Problems for the family began when their Dominicana flight landed in the Dominican Republic, and immigration officials denied them entry. Forced to leave, the family was shuttled first to Puerto Rico and then to Haiti, where they had to secure their own passage back to the United States at additional expense. The family brings suit for battery, false imprisonment, breach of warranty, and breach of contract against all four different business entities. The Dominicana Airlines asserts the act of state doctrine as a defense. Explain whether this defense applies in this situation.
