AStA is the collegial management body and is authorised by StuPa, the executive body representing the interests of all students. It is elected by StuPa for a term of one year and manages students' affairs as well as representing it externally. It consists of different departments and the management board (e.g. for higher education policy, social affairs, culture or sports).
It is financed by the semester fee which is paid by all students. StuPa determines on how the semester fee is used when it decides on the budget.
