Abstract
Many recent publications on lobbying at the European Union level question the position and role of established Eurogroups which represent business interests. The federate Eurogroups in particular draw reservations from various observers. At the same time, the advantages of alternative formulae for collectively defending and promoting business interests at the European Union level have been outlined. One example is the direct membership Euro-association of companies. Another type of collective business lobby at the European Union level that could also be an attractive alternative to relying on Euro-federations is the ad hoc coalition of companies. This article presents an exploratory case study in which the latter is analysed.
