Beurteilungsspielräume im Europäischen Verwaltungsrecht am Beispiel des Migrations- und Umweltrechts

»The Margin of Appreciation in European Administrative Law based on the Example of Migration and Environmental Law. On Final Decision Powers and Authority in the Multidimensional System of the European Union and their Effects on the Procedural Autonomy of the Member States«: So far, there has been a general understanding that European administrative law is unfamiliar with the fine distinction between the margin of appreciation regarding legal facts and legal implications (so-called administrative final decision powers), which is a central element of German administrative law dogmatics and which has been decisively promoted by the latter. Decisively, this understanding stems from the early economic administrative law of the 1980s, which can hardly cover the scope of today's existing legal frameworks. Against this background, the thesis puts a possible dogmatization of the existing understanding of a standardized administrative final decision power on trial and makes an attempt at a methodical integration in the multidimensional system of European administrative law. The investigation is not carried out from the abstract perspective of the German system (»General Part« and »Special Part«), but rather from the concrete reference areas of the specialized law.
