Division IV is responsible for matters pertaining to asylum.
Like Division V, Division IV handles complaints filed against decisions of the State Secretariat for Migration (SEM) (e.g. decisions to discontinue examination of an asylum application, to reject an asylum application as well as to issue and enforce removal orders). Division IV is also responsible for handling appeals against decisions to revoke temporary admission within the framework of asylum proceedings or against preliminary decisions to deny entry or to require individuals to remain in a designated area within the airport.
Unlike the other three divisions of the FAC, Divisions IV and V rule in the last instance. Their judgments cannot be appealed before the Federal Supreme Court (FSC). A characteristic of the Asylum Act (SR 142.31) is that it authorises substantive judgments to be rendered by a single judge in certain cases.
