Aer Lingus is challenging the Commission’s decision of 11 October 2007 to reject a request to force Ryanair to dispose of its minority shareholding in Aer Lingus. This decision and appeal to the Court of First Instance is based on the Commission’s decision in June 2007 to prohibit Ryanair’s acquisition of Aer Lingus on the basis that it would create or strengthen a dominant market on certain airline routes. An appeal by Ryanair against the Commission decision blocking the merger is already pending. In this latest appeal, Aer Lingus contends that following the failure of the merger the Commission must restore the position prior to the attempted acquisition or put in place interim measures.
