As an expert in extradition law, Dr. Hagen has extensive experience defending clients threatened by an international extradition request, a European Arrest Warrant, an SIS alert or an Interpol Red Notice.

Extradition proceedings often turn out to be human rights proceedings. In many countries, those affected can neither be guaranteed humane detention conditions nor a fair trial. With his work, Dr Hagen, therefore, makes a significant contribution to the protection of fundamental and human rights guaranteed by the European Convention on Human Rights.

As a valued member of the legal team led by Mr. Aykut Elseven, Dr Hagen has an outstanding track record, which shows him to be a reliable partner for people in a crisis. In addition, Dr Hagen is valued by his foreign colleagues as a valuable external advisor who has a stable network and extensive contacts with the authorities involved.

Dr Hagen’s clients include high-ranking international politicians, businesspeople and well-known personalities. As a committed lawyer, he regularly supports our clients with their economic and tax criminal proceedings. With his expert service, cases usually end with the discontinuation of the proceedings, an acquittal or a mere warning.
