(Telecompaper) The proceedings for the approval of Telefonica Germany's takeover of E-Plus might be reopened as new telecom operator Airdata filed a complaint at the European Court of Justice against what it said were inadequate controls by the European Commission. According to Airdata CEO Christian Irmler, the EC should not have approved of the takeover because the commitments made by Telefonica are not enough to pursue vigorous competition. The administrative court in Cologne will deal with this matter on 10 June in a public hearing.
