Horizontal cooperation
in EU law has created ‘transnational administrative acts’, whose legal effects
unfold not only in the issuing Member State, but also in other Member States of
the EU. The European legal system of horizontal cooperation and shared
administration is increasingly dependent on the mutual recognition of foreign
administrative acts. At the same time, however, territorial extension of the
legal effects of these administrative acts limits the legal remedies available
to the parties outside of the issuing state. In Germany, the issue of
transnational administrative action has been studied extensively in legal
science since the early 2000s. On the basis of selected case law from the
reference areas ‘genetically modified organisms’, ‘pharmaceuticals’, ‘asylum,
migration and visa’, ‘European driving licences’ ‘taxes’ and ‘social security’,
the following analysis will present, how German courts treat foreign
administrative acts with transnational effects. The study will be structured in
line with the categorization of transnational administrative acts, which has
emerged in German scholarly literature.
