CYIL 7 ȍ2016Ȏ INTERNATIONAL ADMINISTRATIVE LAW AND ADMINISTRATIVE ACTS… as established by Directive 2009/54, 68 the issuing of licences for the provision of air transport services for passengers, post and/or goods pursuant to Regulation (EC) 1008/2008 69 as well as the authorisation for the exercise of credit-provision activities according to Directive 2006/48. 70 As highlighted in particular by several German scholars of administrative law (in particular by Joachim Becker , 71 Volker Nessler 72 and Matthias Ruffert 73 ), the transnationality of an administrative decision can be connected either to the effect itself (when a measure allows the recipient from one particular Member State to exercise an activity also in another Member States), or to the recipient itself (when the competent issuing authority and the recipient of the measure are in two different Member States), or that connected to the issuing authority (when a administrative authority can issue a measure or carry out an administrative activity in the territory of another Member State). However, this listing is hardly to be considered as exhaustive. 10. It is a matter of fact that apart from cases when so provided by a corresponding international agreement or by an act of recognition, 74 other cases of horizontal transterritorial effect have been rather rare. However, the cases of “transterritorial” administrative decisions which are to be found in many provisions of EU law do represent a considerable challenge in this respect. The fact is that, while having transterritorial effects, these acts still remain administrative acts issued and regulated by national administrative law. Consequently, even when having effects also in the territory of another state, it is basically the public order of the “domestic” state which governs them. Consequently, the state is obliged (by directly applicable provision of the EU law) to tolerate effects of foreign administrative decisions on his sovereign territory, without having power to accept such effects by a formal recognition, or by participating at the applicable administrative proceedings. Naturally, this fact opens the doors for discussions on common EU code of administrative proceedings. 75 68 Directive 2009/54/EC of the European Parliament and of the Council of 18 June 2009 on the exploitation and marketing of natural mineral waters. 69 Regulation (EC) No 1008/2008 of the European Parliament and of the Council of 24 September 2008 on common rules for the operation of air services in the Community. 70 Directive 2006/48/EC of the European Parliament and of the Council of 14 June 2006 relating to the taking up and pursuit of the business of credit institutions. 71 BECKER, J.
