Yazaki Corporation and DENSO Corporation are both Japanese companies that supply electrical components to manufacturers of automobiles. Following an investigation by the U.S. Department of Justice in 2012, the two companies agreed to plead guilty to price fixing and pay a total of \($548\) million in criminal fines. Four executives of the companies, all Japanese nationals, agreed to serve prison sentences ranging from 15 months to two years in U.S. prisons. Has Congress authorized the U.S. Department of Justice to investigate price-fixing violations where neither accused party is a U.S. business? If so, what is the legal standard? Once the companies have paid the \($548\) million in fines and the executives have served their prison terms, does this mean the companies and individuals have no further liability? What other authorities might impose further penalties or prison sentences, if any? What other plaintiffs might bring suit, if any?
