Mr. Ghosn was arrested by an organization called the Special Investigation Department (Tokusoubu). Tokusoubu is hated by politicians and corporate executives to investigate corruption and financial crime. The authorities were always trying to shut down Tokusoubu, and in fact were weakening. It is unlikely that those in power will be able to intervene in the judiciary, but if Mr. Ghosn is acquitted, Tokusoubu is likely to be closed down.
