JAKUB HANDRLICA CYIL 7 ȍ2016Ȏ nature (e.g. delivery of an order expelling a foreigner from the territory), (h) last but not least, Karl Neumeyer mentions 58 examples of transterritorial administrative decision making being based on the customs of international public law (e.g. granting a promotion into the ranks of nobility); however, he admits that these examples were already outdated when he was writing his work (1936). The issues of horizontal transterritorial effect became a later subject of interest of several later authors. In particular, Klaus König, 59 Dave Siegrist 60 and Käte Weiss 61 are to be mentioned at this place. Despite a quite extensive list of scientific literature dealing with this topic, the issue of horizontal transterritorial effects of administrative decisions seems to still represent a rather poorly researched area nowadays. This statement was very recently reaffirmed by the introduction to the monograph on “Recognition of Foreign Administrative Acts” , published in 2016. 62 9. It is a matter of fact that only a few international agreements have provided for horizontal transterritorial effects of administrative acts. The Vienna Convention of Road Traffic of 1968, which provides for transterritorial effects of driving licenses, represents an example of such an agreement. In EU secondary legislation, however, the level of formalisation of these transterritorial administrative acts has become high enough 63 to allow for the identification of decision making paradigms which are characterised by a significant level of coherence. For these reasons, these “transterritorial” administrative decisions are coming under increasing scrutiny in the ( inter alia ) French, 64 Italian, 65 German 66 and Austrian 67 public (administrative) law. The topic is complex, as numerous examples of administrative decision making with transterritorial effects can be found in the valid EU secondary legislation. Worthy of mention here, for example, are authorisations for the sale of mineral waters 58 Neumeyer, K.
