»Non-judicial Remedies in German Administrative, Tax and Social Law«Administrative procedures and administrative process law is characterized by a division into three parts: general administrative, taxation and social law. The issue of standardization is fundamental. The thesis compares the preliminary extrajudicial procedures.
