The Institute of Public International Law, Air Law and International Relations is in charge of these fields of law in research and teaching.

As far as teaching is concerned, the Institute is responsible for conducting courses and exams as part of the diploma course of studies (in the basic course as well as in various specialisations) and the doctorate course of studies as well as the supervision of scientific research papers (diploma theses and dissertations). The members of the Institute teach Public International Law and European Law and offer a broad variety of special additional courses, many of them as part of the specialisation "International Law". Additionally, the Institute is deeply involved in the multi-media teaching programme of the Institute for Multimedia Law Studies.

The Institute's research areas cover Public International Law, European Law and Air Law, the latter having found its way into the Institute's official name after having already been a research priority for a long time.
