German network operators Deutsche Telekom, Tele Columbus and NetCologne are taking legal action against the European Commission’s decision to approve the controversial takeover of Liberty Global’s German cable company Unitymedia by Vodafone.Three so-called actions for annulment have been filed at the Court of Justice of the European Union against the approval, a court spokesman confirmed to German industry newsletter Medienkorrespondenz.The plaintiffs had previously criticised that the “re-monopolisation of the cable market” would weaken competition.On February 4, 2020, the deadline expired for taking legal action against the European competition authority’s approval of the cable deal at the Court of Justice of the European Union.
